Background

A printer is a machine that prints text and images. 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. The invention and the development of the printing machine play an important role in the propagation of human civilization and culture.

In the imprinting process of the printing machine, the clutch mechanism is a very important structure, which directly determines the printing quality, and the chinese patent network publication No. CN109177449A discloses a plate roller clutch-pressing mechanism of a flexographic printing machine, which comprises an imprinting cylinder rotationally fitted on a frame of the flexographic printing machine, an anilox roller rotationally fitted on a printing unit, the printing unit comprises a lifter, shoulder irons which are fixed on two sides of a unit frame of the printing unit in a sliding fit mode and are matched with a driving end of the lifter, and a printing roller which is matched with the shoulder irons in a rotating mode, wherein the printing roller, an imprinting cylinder and an anilox roller are in a pressing or separating state. Although the problem that the combined pressure of the existing printing roller, the imprinting cylinder and the anilox roller is unstable, and the inking and inking uniformity of the printing roller is poor can be solved, the adjustment operation between the printing roller and the imprinting cylinder and between the printing roller and the anilox roller is troublesome, and the maintenance is very difficult when the printing roller is damaged, and meanwhile, the printing ink on the printing roller is difficult to be uniform during printing, and the printing effect is poor.
