Chuan Ling Machinery Co., Ltd. is a professional manufacturer of all kinds of printing machines and processing equipment. Founder Luo Jinchun entered the machinery industry in the early years. He founded in 1973 in Taoyuan Yangmei, and provides high-quality services with innovation, service and practical spirit. This is handled by the second generation of Mr. Luo Wenfa and still maintains a diligent and pragmatic family style. He is committed to the improvement and innovation of printing machinery, creating a number of patents to make printing more precise and more beautiful. In the printing of letterpress trademarks, there is a core component of the intermittent trademark printing machine. Chuan Ling's built-in CNC driving motor can directly perform digital positioning of paper advancement and abdication, achieving transmission-free and precise advancement and backward paper steps. Into the positioning ability, to achieve more convenient and accurate reciprocating positioning intermittent printing effect. In addition to the intermittent letterpress printing machine, Chuan Ling products also have the development and manufacture of screen printing machines, die-cutting machines, hot stamping machines, inclined-arm type trademark printing machines, slitting machines, etc., and live the world with excellent quality. Major press exhibitions, such as the Label Expo in Belgium, the Guangdong and Shanghai Trademark Exhibitions, have won a market recognition. Customers include the world's advanced countries in Europe, America, Japan and China. There are also trademark users of Chuan Ling in China. From the early oblique arm type trademark machine, screen printing machine to intermittent letterpress trademark machine.
In recent years, the trademark printing machine has developed in three directions, namely the non-ink key type Flexo flexo trademark printing machine. The biggest advantage is that the printing is easy, the quality is stable, the ink color is fixed, and the addition and subtraction of the ink color is replaced by the replacement of the Anilox Roller micro-cavity. In addition to the ink roller, there is almost no way to change the color of the ink. Only in the prepress equipment and the manufacturer with good color management can it be used smoothly. It is difficult for the letterpress printing factory that has been used to adjust the ink supply to change. In addition, there is no version of digital trademark printing and electronic imaging, such as toner Xeikon 6000, 7000 to 8000, paper-to-roll paper feeding, printing, delivery, and HP Indigo WS 4500, WS 6000 are also non-printing For the production method of the roll, the big advantage is that it does not need to bake and cure the toner, so it is not advantageous to deform and warp on the thin paper and film printing, which is advantageous. Recently, a series of inkjet trademark printers, including Epson, Domino, Founder Eagle Jet, Screen, Mimaki, etc., have been launched into the UV inkjet production trademark printers. Digital printing is not a long-term solution for Chuan Ling, so it has been actively engaged in the research and development of trademark lithographic printing presses more than three years ago. It hopes to provide high quality by using lithographic printing, which is both fine and fully digital. A low-cost, fast-process printing plate. In addition, the lithographic UV printing is very mature on the ink and drying equipment, and the lithographic size is also very easy to grasp the advantages, so Chairman Luo is moving towards this ideal. The old founder also relies on printing machinery for many years. Manufacturing experience, providing a lot of constructive advice to develop trademark stamping machines.
Chuan Ling's SPM-450 trademark lithographic printing machine adopts unit type combination and independent numerical control servo motor drive mode. The paper adopts intermittent advancement full circumference combined with backward adjustment amount to adjust the change of printing die length to make the circumference size. Change adjustment. Ink supply is a multi-ink roller arrangement of four ink rollers on the layout. It is equipped with a continuous water supply humidification system and a refrigerated water tank liquid cooling circulation system. The ink color adjustment area is colored with a dense hand rotation type and a touch operation screen. Control press operation on the screen. Luo Dong’s cautious personality is prudent for every manufacturing step. First, I found a professional company in electronics and electrical machinery in Japan. Not only does it provide a lot of program control and matching of trademark printers, but more importantly, Chuan Ling lacks wet systems. Experience has become the biggest challenge of this transformation. Because letterpress printing has no oxidative drying function in the use of UV ink, the viscosity and fluidity of the ink change little. It is not easy to crust like ink using absorption and oxidative drying. The viscosity is large and the fluidity is deteriorated. Therefore, the change of the ink color of the letterpress printing is only determined by the simple dichotomy that the ink color is too thick, the ink supply is too much, or the ink color is too light, and the ink supply is insufficient. However, lithography is not only a change in the supply of ink but also a number of causes of water supply. If the ink color is too light, the ink layer may be too thin, or there may be two possibilities that the emulsification is large and the concentration is lightened. Or the ink is too light, too much water and so on. The ink is too strong to be the single factor to reduce the ink, but after the ink is lightened, it is found that it does not reduce the water, because the water is supplied with the ink, so once the ink is lightened, it is found that the water is Too much, such a linkage-type ink-and-wash balance state is not easy to solve at a time, and must be analyzed by experienced technicians, but experienced masters may not be able to determine the operation with great agility. SPM-450 can print in a width of 460mm and a circumference of up to 400mm, because it is the size of the intermittent adjustable printing circumference, without replacing the tube, rubber ★ diameter, the length of the paper back to the printing week From short to long changes, Chuan Ling has many years of experience in this area, but for thin printed materials with poor stiffness, it is not difficult to pull forward, but vice versa when going back to adjust the size, or Due to the high ductility of the printed materials, it will be inaccurate, not only the set of pairs but also the problem of changing the version.
Chuan Ling is very cautious in the machinery and motor of the printing machine. It has a large, wide machine and advanced double slide rails. It is used for the walking and locking design of each printing unit group, and uses the CNC motor to drive the walking mode to adjust the printing. The front and back overprinting position is much more convenient than the general rotary or sheet-leaf printing machine. Even the knob can be manually adjusted to adjust the front and back of the plate, and the deviation of the printing can be adjusted from the printing unit base and the upper ★ tube printing unit. It is thanks to the independent drive, which makes the operation very convenient and simple, and it is difficult to avoid the gear meshing deviation of the power transmission between the units. Many advanced sheet-leaf printing machines use a "wall panel" structure, and each unit of the Smooth 450 has a reinforced box structure with a thick double-sided wall of 180 mm. The first is to ensure the strength of the printing. More important is to prevent vibration. The second is the high-speed operation of the ★ hollow part of the cylinder and the embossed part, which absorbs the sudden change of pressure and sudden change of vibration, and can work more smoothly. It is believed that in many trademark printing machines, there is no solid structure. Although a bit too solid, it is far better than insufficient. In terms of water roller, there are two main sink rollers and a plate water roller. The sink roller is coated with a ceramic surface and has good hydrophilicity. The water roller and the plate water roller are used on the surface, and the rubber with good hydrophilicity is used. It is manufactured and has a riding roller but is not used in a hybrid manner to emulsify the first surface registration roller. Arranged in the ink supply system, it is completely like the advanced sheet-leaf printing machine structure. Unlike the short ink path and the less ink roller method of the general rotary machine, the amount of ink saved is relatively large, and it is easy to respond to the full version and the ink color. The hard water roller is chrome-plated, the hard ink roller is copper-plated, and it is relatively hydrophilic and lipophilic. The rubber of the ink roller is made of anti-UV ink. The blanket is made of Jinyangshe anti-UV ink cushion blanket, and the UV curing system is the UV lamp of the light source company. The long-time light source cooperates with Chuanling's trademark printing machine, which continues to be used on the trademark rotary printing machine. UV ink curing is relatively simple, only the thickness of the ink layer and the penetration of ink and UV light, but the lithographic printing has more water-emulsified UV ink factors, water emulsification in the UV ink, how much will reduce the drying speed of the UV ink Even if the UV ink is irradiated, there is too much emulsification to affect the penetration of UV light, and the absorption of ultraviolet light by the moisture to convert the heat into evaporation heat, etc., which increases the dry curing and the cause of ink overprinting. There are many new reasons for the design and manufacture of trademark printing presses, the selection of printing materials, and the stability of printing effects. For this reason, Luo Dong has to consider many factors in addition to machinery. s solution.
Chuan Ling has decades of experience in printing press manufacturing, but the problem of ink and wash balance in lithographic printing has never been discussed in depth. Now, once it is changed to a lithographic printing press, it is necessary to familiarize with the key technical problems of lithography. Otherwise, Unable to print qualified products. The first is the adjustable roller design that faces the water roller system to do ink mixing. Finally, the resolution uses a separate water roller system that is easier to control, and uses the most easily hydrophilic ceramic surface to coat the water roller, hoping to reduce alcohol wetting. The percentage of alcohol running in the system, the target is operated with 3 to 5% isopropanol content, but sometimes it can be reproduced by 7 to 8% or even 11% due to printing or environmental changes. It is better, mainly when there is no air conditioning equipment in the factory during the test run. In the morning when the machine is cold and the temperature is low, it seems that everything is going well, but by noon, the machine is running in a higher temperature environment, plus the machine starts to heat up, The large amount of temperature generated by UV light, although the cooling system device still makes the ink soft and sticky, it is also prone to ink emulsification, dirty water supply system, uneven water supply, and increased IPA isopropyl alcohol percentage In order to have a better printing effect. Chuan Ling has produced more than 10 flat printing machines. During the test, there were old customers who came from domestic or far from abroad and even Germany, and changed from the letterpress to the flat-printing trademark machine. Everyone in the Yangmei factory learned from each other, but because the machine was Under the control of temperature and humidity, there are quite a lot of difficulties in printing and a big test. After that, the machine enters the customer's printing factory. In the constant temperature and air conditioning environment, the problem of ink balance and cooling can be solved. Therefore, the author Luo Dong suggested that if it is impossible to do full room air conditioning in a large factory building, it is advisable to install a air conditioner in a dozen or 20 ping large measuring machine, so that the lithographic printing machine can have more stable environmental testing conditions. The temperature of the large water tank during the test is 8~10 °C, but the temperature of the small water tank on the printing unit is below 20 °C, which fully exerts the cooling effect. In fact, it also faces the alternative of less alcohol consumption or alcohol-free. In design, Luo Dong is very particular about the abundant energy equipment. For example, the cooling water tank uses a device that is twice as large as the freezing force. Not only four colors and six colors are available, but the eight-color machine can still be used to cause no shortage. The forward and reverse pressure of the water roller and the ink tank is much more complicated than that of the letterpress machine. When the letterpress printing surface ink roller is not printed, it does not need to be lifted up, off the plate, and rotated to be printed. However, when the lithographic printing is idling, not only the printing ink roller can not rely on the plate, but also the water roller can not rely on the plate feed water. When the pressure printing is to be started again, the water roller must be pressed several times to turn the dried printing plate surface. Wet, otherwise, if the water roller and the ink roller are pressed at the same time, the stained plate and even the entire layout will be black. Therefore, according to the electronic program experience of the Japanese electronic motor supply factory, Chuan Ling has planned in advance, so it is done. It's a lot smoother. In fact, it seems to be simple, and there are very few differences in the appearance of the embossing machine and the flat printing machine. Under the different printing principles, although it brings a lot of convenience, it also has a lot of complexity, and now it has developed towards this road. It’s going to be a success.
The printing machine used CTP printing on the fashion, and used Chuan Ling's Japanese (T brand) UV printing ink to print products that customers felt very good, but soon the UV lamp manufacturer told us that the new machine The customer complained to the light source company that the illuminance of the UV lamp was insufficient, and the surface of the printing ink layer was only dry, and the inside was still soft, and the rubbing was broken and the ink was smeared. Luo Dong felt strange and led the technician and the Japanese flat. UV ink was printed and tested. It was found that the customer used the original letterpress UV ink to find the problem. The problem was not caused by the lack of illumination of the machine and the UV lamp, but the UV ink was not suitable. For the manufacturer of the machine, the essence of doing business is to make a profit. If the cost is too high, the benefits will naturally be compressed. Later, the customer can understand that the printing plate is cheaper, the printing plate is faster, and the printing size is larger. However, under different layouts, there are always some different conditions to be accepted. It is necessary to find the new low-cost materials before the production is completed. Otherwise, it is only cheap to print and not good. use? In the future, whether to strengthen the full-format CCD camera, scan the entire print and color comparison, not just partial quality control. The lithographic printing machine uses the CTP version, so it is unreasonable to control the opening degree of each ink tank key with the screw currently used. It is unreasonable to control the ink opening method. There is no real control over the amount of ink to match the print. It is best to use the digital ink tank key control method, which can be used with CIP 3/4 to accept the information flow of the prepress part, and to make the most accurate opening adjustment of the ink key. Luo Dong also makes the number with the Swiss supplier. The technical cooperation of the ink key, I hope to have the information application adjustment of the CTP plate printing, and become an advanced equipment of choice. There is also a compromise between manual adjustment and digital ink control. Instead of using a non-screw eccentric to open the ink groove of the ink tank, the handle is used to pull the eccentric to control the amount of ink. How many, although the manual adjustment of the ink key, but the eccentric shaft with a long handle to adjust the up and down, you can make a 0~9 dial indication, forming at least 20 steps of reading, not only convenient to zero, Adjustment, can also be used to control the distribution of each ink button on the printing plate printed by CIP 3, to achieve scientific scientific ink control technology with manual regulation and control without information connection. A new type of lithographic printing machine should have more automation and scientific data processing equipment. This is where Chuan Ling Company really wants to work hard. Chuan Ling has also installed a synchronous continuous inkjet printing barcode machine to achieve synchronous digital printing. The variable print effect, all of which is within the scope of Chuan Ling's efforts.
