Description

Printing device

Technical Field

The application relates to the field of printing, in particular to a printing device.

Background

Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate.

When a printing machine is used for printing, paper needs to be rolled from a plate roller of the printing machine, and patterns are printed on the surface of the paper along with the rotation of the plate roller. When the paper rolls from the plate roller, the paper cannot be well attached to the surface of the plate roller, so that the printing effect is poor, and the printed pattern is unclear. The existing printing machine drives the press roller to swing up and down through a driving mechanism such as an air cylinder and a motor to press paper on the plate roller, and has the problems of high production cost, complex control and high operation difficulty. Meanwhile, the same printing machine cannot print paper with different thicknesses in a self-adaptive manner, and different printing machines are required to be used for printing paper with different thicknesses, so that the problem of high production cost is also caused.
