It is a auxiliary equipment of multi-color printing machine. For glazing, it can increase the brightness of the product and the storage time of the product color. Improve the quality of products. It can also be used for printing monochrome stickers and various supermarket labels.
1. The structure of the machine is simple, so the operation is convenient, and it is easy to repair and maintain. The price of the same function's flexographic printing machine is about the 30-50% of the offset press or the gravure machine.
2. The genetic material is adaptable, and the corrugated board from 0.22 mm to 10 mm can obtain satisfactory printing effect.
3. Small print force, about 19.6-39.2 N/square cm, especially the printing of a type of corrugated paper which can not bear too much pressure.
4. Low printing costs, mainly due to the low cost of the machine, low cost of printing, low loss of paper in the printing process, and the production cost is 30-50% cheaper than the gravure print.
5. Good quality of printing. The anilox roller short inking system of monlchamus Road, not only simplified the structure of inking system, but also can achieve the quantitative control of film thickness. The technical breakthrough of high performance photosensitive resin has greatly improved the resolution of printing plate and the reproducibility of nodes (can reach 1-95%). Flexographic printing can achieve 300 wire/in color level printing, printing effect can be compared with offset printing and gravure.
The printing plate of flexographic printing has been made with a rubber version, and a solid or liquid resin version has been used.
Compared with other printing processes, the feature of the plate is a "soft" word. Flexible plate printing has a strong adaptability, which can not only print thicker corrugated cardboard, but also print thin and soft plastic film. It can print absorbent paper towel, and also can print non-absorbent aluminum foil and other materials. Due to the adoption of liquid ink printing, packing materials and soft and smooth, it can better overcome the material surface rough printing problems, and then get the thick and colorful printing effect of ink layer.
The reel feeding part is also equipped with a digital controlled electromagnetic braking tension system, and the structure of the tension control system for the reel feeding parts and the flexographic machine. It can make the best tension control for different bearings and is not affected by dust and dirt. The tension compensation control adopts loop self detection system. When the diameter of the reel paper is decreasing, it can keep the tension of the paper or film stable.
The reel feeding part is also equipped with a driving roll mechanism. The drive roller is an easily adjustable variable speed feed roller which controls the steady entry speed of the roll paper. It produces the unwinding tension of the material belt together with the material coil brake device, so as to adapt to the production of different substrates, such as cardboard, thin paper, plastic film and so on, and ensure that the web is kept at the right vertical position.
The floating roller structure of the uncoiled feeding parts can reduce the fluctuation of the uncoil tension, and shorten the time of downtime when changing the volume, so as to improve the efficiency of the flexographic printing machine. Most of the flexographic printing machines are equipped with a continuous roll change device. In the case of unstopped, it is very important to roll the material well, which is the floating roller.
The feed device is also equipped with an edge control system, one edge control system is installed in front of the printing unit, and the other side control system is installed in front of the die cutting table. Such a design keeps the material in the correct position throughout the production process.
