As an important printing machine, paper bag printing machine has good application in many industries. What are its structural characteristics?
1. It adopts the structure of sleeve printing plate cylinder and anilox roller, which makes the upper and lower printing plates simple, flexible, convenient for storage, high system precision, and has the function of "quick plate change".
2. The unloading receiving unit adopts the double-arm double-position rotating frame of the separation tower, which has the function of high-speed non-stop roll change.
3. The drying box adopts the direct air inlet type, with small air loss and high efficiency. The oven with new structure can realize the secondary utilization of heat energy and is controlled by an intelligent constant temperature system.
4. The closed double scraper chamber ink feeding system is adopted to reduce environmental pollution, facilitate quick cleaning, and reduce ink change time and downtime. The doctor blade unit is pneumatically pressurized and the ink chamber is closed. Features swivel and quick release for cleaning and changing blades and ink sticks.
5. The wall panel adopts an integral structure, which is not easy to deform.
6. The central embossing cylinder adopts a double-wall structure and a constant temperature water circulation system to keep the temperature of the outer surface of the embossing cylinder constant and prevent the thermal expansion of the embossing cylinder; it adopts a mechanical braking device to ensure reliable operation.
When printing products, what are the factors that affect the effect of the paper bag printing machine?
1. When proofing, of course, it is proofing with a laser typesetting machine, and the single precision is between 0.01-0.1mm. However, some errors can also occur due to the different films used.
2. Due to the problems of papermaking technology, the brightness, thickness and texture of the same paper produced by different paper mills will be different.
3. After the printing is completed, the next step is mainly to cut the printed matter with a paper cutter. When cutting the finished product, due to the error of the tool itself, the error after cutting the finished product also exists objectively.
4. Malfunction. One is overprint accuracy and the other is ink color.
