Description

Technical Field

[0002] A flexographic printing press is a device that uses highly fluid fluid ink for printing. Its main features are simple structure, easy operation, and the printing part is the core of the entire machine.

[0003] During the printing process of a flexographic printing press, the ink is transferred to the image and text part of the printing plate through the ink fountain rubber roller and the anilox transfer roller, and the pressure roller applies printing pressure to transfer the ink on the printing plate to the substrate. Finally, after drying, the printing process is completed. When printing, the flexible printing press uses a feeding mechanism to feed the materials to be printed, such as paper, plastic film, etc., into the printing press for printing. The performance and stability of the feeding mechanism affect the quality and efficiency of printing. In the existing feeding mechanism technology of flexible printing presses, when conveying some materials with relatively smooth surfaces, the material may slip or deviate during conveying, resulting in delays or jams in printing feeding.
