Category Flexo printing part is the core part of the arrangement of printing directly affect the operational performance, print quality, printing speed and printing application. According to the arrangement of the printing part of the flexographic printing presses can be divided into the layering, the satellite type and unit type categories. 1, stacked stacked Flexo Flexo (Figure 2), sometimes referred to as accumulation-type flexographic printing press. Independent printing units cascade up and down, press the main wall panels arranged in one or both ends, or colored printing unit is installed on the rack. Each printing unit installed in the main gears on the wall. Stacked mimeograph can print 1-8 colors, but usually 6 colors. Stacked printing press has 4 advantages: (1) roll of paper path can change, namely the use of walk through the strip guide roller to change routes, to a printing positive and negative sides, while the number of transformation is very easy to print and color. (2) print parts with good accessibility, ease of adjustment, replacement and cleaning. (3) can register 360 degrees. Colored printing units can be engaged and separated so that other printing unit to printing. (4) applies to a wide range, you can print a variety of substrates. The main disadvantage is more than indirect gear, multi-color printing, overlay accuracy is not high, only for general printed matter. 2, flexo printing machine flexo printing machine (Figure 3), sometimes a common impression cylinder-type flexographic printing presses. The printing unit around a common impression cylinder mounted between two wall panels. Printing materials around the share color printing on the impression cylinder. Because gear direct drive, so be it paper or film, even without adding a special control device, you can still overprint very accurate and stable printing process, used to print color products. It has been predicted that the satellite Flexographic Printing Flexography is the new mainstream of the 21st century. Its main disadvantages are: (1) to be expected after a press time, only complete single-sided printing. Although the guide roll can be printed on the other side, but due to the line of the strip is too long, increase the tensile deformation and uneven, to achieve both sides of the printing image is very difficult to register. Therefore, flexo printing machine, a thin-film material, after the printing by the vertical air seal, made by both sides of the bag pattern. (2) the short distance between the printing unit, ink rub dry and susceptible to bad dirty. Developed in recent years, UV and UV / EB flexo post-printing by UV ink or UV / EB light can achieve instant dry, rub dirty basically solved the problem. 3, unit-type flexographic printing press unit-type flexographic printing machine by the way the connection type flexographic printing presses, the level of the 4-8 alignment and independent of each other and share power through a shaft-driven printing units. Unit-type Flexographic Press by each version is only supported on a printing unit, so the unit-type flexographic printing machine can be designed to adapt to different drum. Its main advantages are: (1) Unit installed combination of convenience, finishing easy. (2) suitable for printing short life. (3) through the guide roll to change the operation of the strip line can achieve a double-sided printing. The reason why the development of flexographic printing presses features uniform, in addition to plates, ink technology breakthroughs, with the characteristics of its own important reason is to attract users. 1, the machine is simple, so easy to operate, and easy maintenance. Flexographic printing presses the same function of offset or gravure printing machine cost about 30-50%. 2, causes material adaptability, from 0.22mm to 10mm plastic film after the corrugated board can be satisfied with the print results. 3, the imprint force is small, about 19.6-39.2N / square centimeter, in particular, and corrugated paper a class can not put too much pressure on the printing substrates. 4, the printing costs low, mainly due to cheaper machines, plate making low-cost, low rate of loss of paper during the printing and production costs 30-50% less expensive than gravure. 5, the printing quality. Anilox roller with a short inking Ink system, inking system not only simplifies the structure, but also realize the quantitative control of film thickness. Photopolymer technology performance breakthrough, greatly improving the print version of the resolution and dot reproducibility (up to 1-95%). Flexo can achieve 300 lines to / in the color level draft printing, offset printing and gravure printing results can be compared with the United States. Structure of flexographic printing presses are mainly four components, namely, the paper feed solution components, printing parts, dry parts and rewinding rewinding parts. In the modern flexographic printing presses, usually there is tension control, edge position control, register control, printing and observation monitoring plant and machinery condition monitoring and fault diagnosis system. In addition, to expand the scope of application, in some flexo presses equipped with coating, laminating, hot stamping, slitting, die cutting, drilling, screen printing and gravure printing unit and other devices, a flexo joint production line. (A), solution volume parts feeding flexo printing speed generally reach 150m/min (or higher), in normal operating conditions, in order to reduce the number of times and roll down for paper waste materials must be installed to unwind feeding device, simple structure as shown in Figure 5A. Deconvolution is the role of feed loading volume of printing materials will become the start, continuous, and stable parts of the printing material into print, and printed materials into parts to print before the first, control the speed, tension and lateral position. Deconvolution components have a material feed roll stand and a set of guide roller components, aircraft materials in a printed paper parts of a linear arrangement. Frame material volume control with electric or hydraulic lifting devices, pneumatic locking generally roll axis, roll with the end of the detector. (1) Tension Control System Solutions also has digital volume control to feed parts of the electromagnetic brake tensioning system, roll feed solution components and flexo tension control system structure shown in Figure 6. He can be on different substrates to make the best of the tension control, and dirt from the impact of dust. Which compensation is controlled by tension loop-type self-detection system, when the roll diameter decreases continuously, so that can continuously maintain the paper (or film) tension and stability. (2) The drive roller paper feed solution components also installed drive roller body is shown in Figure 5C. Drive roller is an easy adjustable variable speed feed roller, which controls the entry of a smooth roll speed of the printing unit, and together with the expected volume brake volume generated tension of the solution of the strip in order to adapt to different substrates (card paper, tissue paper, plastic film, etc.) production, while ensuring that the web to maintain the correct vertical position. (3) floating roller component deconvolution floating feed roller machine structure shown in Figure 5D addition, you can unwind tension to reduce volatility, while reducing volume replacement downtime expected to increase the efficient use of flexographic printing presses: Most flexographic printing presses are equipped with a continuous roll changing device, in the case of non-stop to pick good material volume, which is a floating roller is particularly important. (4) high-end side of digital control system flexo deconvolution feeding device also has side-bit control system structure diagram as shown in Figure 5B, a side digital control system installed in front of the printing unit, the other side of digital control system installed in the front cutting units. This design make the material volume in the whole production process is maintained at the correct position. (B), the printing parts printing component is the core of flexographic printing presses, the use of short-Ink inking system. Has two rollers, and even accompanied by a doctor blade ink roller, ink can be achieved only by the ink to the plate surfaces are uniform and quantitative transfer. Currently, a typical flexo printing unit used as shown in diagram 7. In this system, the anilox roller for the ink fountain roller, the role of ink fountain roller to the anilox roller (the roller) transfer enough ink. Scraping roller saury match, so you can adapt to a variety of flexo ink viscosity, the higher factors in better print quality. When the printing speed increases, although the roller surface, the dynamic pressure, but the doctor blade pressure in the roller surface, inking system, therefore the amount of ink and ink input dynamic pressure independent, almost independent of viscosity effects. The ink transfer roller depends on the reservoir ink system (volume anilox ink points), and between the roller and ink plate separation of the surface, but not with the operating speed inking system has nothing to do. This short-Ink inking system can output a variety of speeds to maintain a constant amount of ink, it is competent high-speed flexo printing and high-precision color network printing. (1) flexographic printing presses flexographic printing press anilox roller is the transfer roller. The surface of the ink system, a sunken hole or slot line network for the printing ink transferred control of the amount shown in Figure 8. With anilox inking system not only simplifies the structure, and can control the ink film thickness, to improve printing quality provides an important guarantee. Been hailed as the heart of flexographic printing presses. 1, the type of anilox roller is the early use of mechanical engraving copper rollers, and chrome-plated brass roller, to improve wear resistance, increase the carrying amount of ink. Modern ceramic anilox roll technology with laser engraving. Two ink transfer roller has a good performance, but the ceramic anilox price is high. Cable in the print version of high-precision printing speeds of up to 200m \ min, the ceramic anilox roller to better show its wear, heat advantages, but proved: ceramic ink roller easy to plug the hole, the application must pay attention cleaning and maintenance. Because of the metal roller coating, ink easy to plug hole, but not as good as ceramic roller life. Most users believe that, despite the large initial investment of ceramic rollers, but this roller long life (especially in the use of the input doctor blade ink devices occasions), performance (laser engraving can be more sophisticated cable), Compared with the general roller sufficient to compensate the additional expenditure. 2, decided to transfer the ink roller performance parameters of the transfer ink roller ink roller performance perspective point engraving, ink cavity volume, the ink hole depth, network lines, cleaning conditions and other factors. a, angle of the ink roller surface hole carved by the numerous same size distribution consisting of a small concave hole, known as the Mexican cave, shown in Figure 9. Points as the carrier of the ink ink with ink, and even ink reservoir role in the case of high-speed operation can be effectively overcome the phenomenon of flying ink. Anilox laser engraving the latest developments in technology, the Mexican point of a point are 30 degrees, 45 degrees, 60 degrees and 90 degrees, Mexican cave may be intertwined or arranged in parallel to each other. As a computer-controlled engraving process, so the ink roller and the point can be repeatedly copied. Foreign been suggested points of engraving ink roller angle of 60 degrees. b, Mexico Mexican cave temple carved shapes are generally inclined profile, pyramid-shaped, bevel-shaped and so on. Figure 10. Oblique large amount of gear for the ink roller, generally used for painting. To use more modern laser engraved anilox hexagonal openings. Proved that this hexagonal opening for the ink method can produce to avoid Moiré patterns (improper angle plate screening can produce moire). Note, do not use ink hole symmetric circular opening, as the opening round of the ink ink hole hole wall area between the net increase (on the convex part is called anilox network wall), not only reduces the amount of ink, and the decline in the uniformity of ink transfer. c. Hole depth and width of the ink ink from the ink on the point of transfer to the plate with ink ink in addition to the performance, the printing speed and other factors, but also with the depth and width of the ink hole on the ratio, shown in Figure 11. Obviously, if the opening is narrow and deep layers of ink, then ink the ink on the bottom of the hole can not be transferred, close to reduce the ink to the ink hole transfer rate on the plate, and is not conducive to the cleaning roller, the resulting ink permanent plug hole. Practice has proved that: Mexican cave opening width b and depth h was approximately equal to the ratio of R 0.28, the ink transfer more smoothly. General use of modern laser engraved ceramic anilox roller is made, in general, the higher the cable, the more shallow depth of the ink hole, hole depth and width of the ink measured in microns. d, anilox line screens and screen angle of the transfer ink roller cable generally measured by the number. Network lines is within the scope of each centimeter hole carved the number of ink. Generally speaking, the roller of the ink supply line number with the network increases. Practice has proved that: to get high quality printing, anilox roller screen line number should increase the plate number of the network cable to maintain a certain ratio between the number of network cable roller should generally increase with the plate number of the network cable about 4 times. For field printing, if the number of network cable roller is too low, then the ink is too big, the edge of the plate caused by printing ink plot edge ghosting; if the screen frequency is too high for the lack of ink, the field density not the blur. Practice, must be a reasonable choice for the ink lines. Anilox screen angle is currently no unified regulations, the actual work that the ideal cable to 30 degrees and 60 degrees, but the current application is 45 degrees more to determine the screen angle should be to reduce the moire Striped (moire) as the basic principle. e, bulk ink ink hole hole angle, the net number of lines, shapes and ink ink hole depth and width of the hole determines the size of Mexico point, it is by the sunken anilox ink points to transfer ink. Points are generally used for ink volume of theoretical analysis, practical work is difficult to measure its accuracy. At present, the measurement of the ink hole size is the average number of ink points to that the number of ink points = D × π × L × M × M, where D is roller diameter, L the length of the roller, M is network lines. Cave shape of the different ink, different cable and different screen angle can be combined into different ink roller cavity volume, Table 2 shows the capacity of different network cable and the corresponding roller for printing products. Wear and clogging the roller, the actual amount of ink transfer 70-80% of the theoretical value. 3, the cleaning roller transfer roller rotates, the ink on the plate is actually a variable, subject to many factors. Under normal circumstances, the ink amount of ink filled cavity can be transferred to the printed edition is about 70-80% range. Even if the ink itself, the stability and uniformity of dispersion are in line with quality requirements, and the manufacture of precision is also high roller, but he transferred to the ink on the plate is very limited. When printed, the stability of product quality seriously damaged, its not the ink itself the root cause of performance, nor the precision roller, but because of the roller in the course of its work is to dry the ink hole plugging ink due. Hole at the bottom of the ink dried ink, especially after drying water-based ink dissolves in New Mexico is more difficult, unless the dissolution time is very long. Blocking fault will reduce the effective transfer ink ink hole. The basic reasons for its blocking 3: a, replacement of printed materials, the anilox roller cleaning is not complete; b, downtime, no cleaning roller; c, fast ink drying performance. "We must first of its profits." Therefore, to maintain the exact amount of ink transfer, must be reasonably clean roller. Currently, the cleaning method has the following 5 species: a, the chemical solvent scrubbing method of chemical spray in the roller surface of the solvent, according to selection of materials suitable for the fine roller brush (ceramic anilox roller brush with stainless steel, copper metal roller wire brush), scrub with a brush again. This method is only suitable for coarse cleaning of the anilox roller cable. Advantage of low cost, easy to clean, do not pollute the environment; disadvantage is unable to penetrate into the ink hole scrub, so cleaning is not complete. Difficult to clean the hole at the bottom of the dirt and ink for ink. Therefore, the ink cavity volume can not be recovered. b, chemical solvent soak all or part of the invasion of high-roller PH corrosive cleaning agent tank should allow solvent to soften the dried ink, and finally washed with water and caustic cleaning solution and softened by the full corrosion ink, although this method is more effective, but long-term use, corrosive solvents will penetrate protective layer, corrosion of steel body, is not conducive to environmental protection. c, ultrasonic cleaning method on a roller Baptist chemical cleaning solution, full system, ultrasonic cleaning tank, tank conversion device sends high-frequency sound waves, is the solution of vibration and bubbles, the ink cavity dry ink, resin, painted cloth in the solution surface vibration and bubbles generated by an explosion targeting the joint action within the explosive, from Mexico and points in one go with the cleaning fluid. Cleaning time, depending on the size of the base ink roller block the case may be, it normally takes 0.5-24h. At this time, the long-term in high-frequency ultrasonic vibration roller, will undermine the ceramic layer, the ink roller, ink cavity will cause some damage. In addition, this method covers an area of large, high cost, complex process, although there are certain cleaning effect, but this method is perfect, yet to the actual test. d, low-pressure spray cleaning method using two sodium carbonate, baking soda, as the washing powder, spray at low pressure roller, it can be thoroughly cleaned hole left in the ink dry ink, resin, coated fabrics, etc., but note that jet Pressure should not be too high, or they may be from the roller body of the ceramic layer from the general pressure of not more than 0.1MPa. Due to the sodium carbonate, sodium bicarbonate is a softening of the cleaning medium, soluble, non-toxic and harmless, conform to the current global environmental requirements. Proved: a good cleaning effect this method, you can restore point ink volume, and can be cleaned on-site directly, but also ink fountain, grease, ink and so on. Although this approach was developed in recent years, but a lot of potential, worthy of promotion. e, small plastic beads principles with low-pressure jet cleaning method similar to the spray method, but washing powder is used in small plastic beads. This cleaning method can speed the cleaning roller by 30%, and can improve the quality of printed products can also extend the life of anilox roller. This method is less consumption of plastic small beads, the cleaning process without any discharge of hazardous substances and chemical precipitation, is environmentally friendly, efficient and safe. This point was flexo ink in the ink block headaches, with 10 times or 20 times magnifying glass ink hole can be clearly observed congestion. Printing process from the point of view, the general requirements of flexo ink 1.2 grams per square meter (UV ink is less), if the 60-degree angle of the ink cavity, the number of network cable roller 300 lines / in, the ink cavity volume was 3.5 cubic centimeters per square meter. Using this roller, the ink can transfer the ink points amounted to 40%. Graphic part of the ink plate thickness of about 1.5 microns, which is the lowest rate of network expansion. (2) doctor blade device is the role of doctor blade surface, scrape off the excess from the anilox ink, printing plates to better control the amount of ink transfer roller. Ink curing bad (too fast or too slow), ink chemical composition ratio of properly, uneven ink absorption failure, will affect the scraping effect. Flexo ink particles of organic pigments are generally 2-5 microns in diameter, these small particles usually does not cause wear and tear over the knife. However, the pigment particles in the ink particles in the bond and make it larger, and some pigment particles 10-25 microns in diameter, when the inhomogeneity of pigment dispersion will accelerate the wear of doctor blade, the performance of scraping , so the ink must be fully dispersed prior to use. Saury roller scraping with the use of quantitative amount of ink can lose control. As in previous analysis, it can be to adapt to a variety of flexo flexo ink viscosity, obtained in the high-speed printing of high-quality printed materials. Squeegee ① two types of devices simple doctor blade device, that a doctor blade tangent to the surface of the anilox roller. This simple device has a positive doctor blade type and reverse type two scraping methods, shown in Figure 12. Forward scraper commonly used in tangent with the roller contacts at a 45 degree -70 degree angle scraping. Forward scraper, and ink to flow from the knife, because the hydraulic scraper will float, it is necessary to put pressure on the blade, which netted an increase of wear and tear. As the hydraulic scraper will float, so there may be foreign bodies in the ink, paper, wool and other passed, would scratch layout affecting printing quality. At this time, you need to constantly reciprocating blade horizontal traverse institutions so that the knife unit complex. Reverse scraper commonly used in the contact point with the roller into the obtuse angle of 140-150 degrees scraping. Reverse scraper, residual ink out from the outside, do not put additional pressure not to harm grain roll. ② sealed reverse double blade device. Shown in Figure 13, this device consists of ink chamber (also known as the blade seat), two scraper, two with Mexican-style soft materials wear the side seal plate and anilox ink to form a closed cavity. Ink into the ink chamber from the mouth and out of Mexico ports, pump the ink through into the mouth of the anilox flexo ink jet to the surface and stored in the ink chamber, after inking scrape scraping by, hanging under the ink can continue to recycle. Because closed-end ink, so a good seal, the ink can effectively reduce the leakage of the volatile and odor, great for health and environmental benefits. This closed-end device can also be adjusted by means of heating or cooling the ink viscosity, but can also add cleaning device, convenient to the product of the ink roller ink cavity clean in time to ensure a stable inking performance. Need to add that the role of two different blade, a piece of the reverse type, into a reverse blade, which hung suspended on the extra ink roller effect; another piece of the positive type, a positive sealing blade, from sealing effect. (3) dry part of the flexo printing on the two components (units) to go with a length of between 250-400mm, while the rate of general flexo to 150m/min, which means that the volume of a material point of time only after drying device as a fraction of a second one to a dozen, so dry flexographic printing presses requires good drying efficiency devices. Flexographic printing press dryer is divided into two levels: one is between the color dry, that is until the next printing unit so as to dry completely before the color ink, and the other class is the final drying, the ink in all colors After printing, to completely rule out the ink in the solvent, so as not to rub caused by stack rewinding or dirty fault. ① using water-based or solvent-based flexo ink drying component parts of such drying methods using heat and dry the ink drying, hot air heating element is a tube and infrared LED. After heating and drying, the ink in the solvent can be volatile, but when the ink is heated in the dryer, ink oil compound may also be connected in the adhesive state, you must install the cooling device cooling to avoid the rewinding or follow-up of resin processing and curing flexo printing speed and dry heating temperature is high, you must install the cooling roll or cooling device, thermally efficient, but also to ensure that dry and hot air is not escaping from the wind shield to avoid ink on the plate caused by adverse effects. Installation of heating and drying in two ways: one is installed in the lower part of flexographic printing unit. Structural stability in this way. The machine can reduce the amount of space; the other is mounted on the upper part of flexographic printing unit, apparently the heat generated by heating and drying to the top of the oven, will not have adverse effects on other components, which is now mainstream. Need to add two points here: 1, as flexo printing speed and dry heating temperature is high, you must install the cooling roller or other cooling device to the printing material (material volume) cooling in order to avoid material volume (especially PVC plastic film, tissue, etc.) generated in the process of heating and drying shrinkage, warping, swelling and other undesirable phenomena hot; 2, in order to reduce the solvent-based ink drying in the heat emission of volatile organic compounds in the process (VOCS), should be accompanied by VOCS post-processing equipment. There are two main post-processing methods, catalytic oxidation and cooling recovery method. ② using UV or UV / EB flexo inks flexo printing press flexo drying part of the two new water-based ink has been replaced and solvent-based flexo ink trend. UV or UV / EB flexo inks 100% solid content, these two flexo inks cured by chemical methods, almost no physical evaporation, therefore there is no problem of environmental pollution; and because they have a non-toxic, instant drying, the ink particles fine, high concentration, good stability, has been widely applied in Europe at present. UV or UV / EB flexo inks used, making the fountain and the drying system changes accordingly. Because UV or UV / EB flexo inks do not diluted, it eliminates the need for thermal drying tunnel, oven product volatile organic compounds (VOCS) post-processing equipment. Because heating and drying method is not conducive to drying ink, so the body and electronic components will not be due to the interference of high temperature heating, high temperature will not result in volume contraction of materials caused by thermal expansion or warpage. Therefore, printing the implementation of greatly increased. Some data indicate that, UV or UV / EB flexo inks with high cost performance, the current amount to 10-20% of its growth rate. UV or UV / EB flexo ink drying system of the light source, most of the mainstream medium pressure mercury lamp, the actual use of the process should pay attention to the following five issues: a heated drying system management. Although UV or UV / EB curing flexo ink drying principle is to use UV (ultraviolet) light or EB (electron beam) curing light instant drying ink, but in light of mercury emissions, UV light, the energy share of only 20 %. IR (infrared) light accounts for 60%, 20% visible light. Therefore, we must remove the IR optical energy generated by the light because the mercury can produce 800 degree heat. UV ink photoinitiators and pigments to absorb UV light energy. The results show that: different color ink absorption ability of UV light are also different, milk yellow and magenta pigments absorb a small amount of UV flexo light can be cured, so its drying performance; and blue and black paint have to absorb more Flexo The UV light to dry and cure and save energy. In addition, the use of UV and UV / EB flexo inks avoid excessive illumination. UV flexo ink for UV light, the remaining (not the full response) should continue to respond photoinitiator 6-24 hours after the so-called polymerization. If you start too light, UV ink film will become increasingly hard until the brittle fracture, the quality of printing should also not be able to follow-up processing. b drying system to keep clean. Foreign practice shows that UV flexo process flexo ink demanding work environment. If poor working conditions, particularly the lower working space plot, even the best drying equipment will not be satisfied with the drying effect. c timely replacement of UV lamps. UV lamp life should be provided in accordance with the manufacturer's rated life use. When the rated life of 1000-2000 hours beyond the time, even if the lamp is still light, it should replace the lamp, as UV light emission when the ability of UV light can not meet the requirements. d reflected light device must be kept clean, the highly polished mirror should be to improve the reflectivity. Therefore, maintaining reflectors clean is a prerequisite to ensure that reflection. e use of UV flexo inks, we must pay attention to radiation, UV light radiation on the human body has certain hazards. In fact, UV light energy is relatively small, with a thin layer of lead sheet and other materials to UV or other appropriate cover can be closed. (4) Rewinding rewinding parts of the printing and dried material to be rewinding reel for storage or subsequent processing. In order to ensure the accuracy of the printing register to obtain uniform tightness, end neatly outlines the rules of the printed material aid volume, rewinding parts are equipped with tension adjustment and control devices, as shown in Figure 6, the tension control system for flexographic printing machine diagram. To reduce downtime, and some flexo rewinder with a number of components used for non-stop volume.
