Material collecting pressing roller device of printing machine

Abstract

The invention discloses a material collecting pressing roller device of a printing machine. The material collecting pressing roller device comprises a supporting table and a machine body. Supporting plates are fixed to the two ends of the machine body, a first rotary shaft rod is arranged above the machine body, a first belt wheel is fixed to the left end of the first rotary shaft rod, a second rotary shaft rod is fixed to the right end of a second belt wheel, and the right end of the second rotary shaft rod penetrates through the supporting plates. The upper surface of a driving pressing roller makes contact with a driven pressing roller, the two ends of a third rotary shaft rod penetrate through the supporting plates, a buffer spring is arranged between the second rotary shaft rod and the third rotary shaft rod, the edge of a rotary wheel makes contact with the driven pressing roller, positioning holes are formed in the surface of a positioning rod, and a printing box is mounted on the upper surface of a top plate. According to the pressing roller device of the printing machine, the problems that impurities are accumulated on the surface of rubber of the rubber-covered rollers, the microporosity of the surfaces of the rubber-covered rollers is lost, the surfaces of the rubber-covered rollers are glazed, and finally serious harm is caused to printing are solved.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a receiving press roller device of a printing machine. Background technique [0002] Printing is to transfer the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, pressure and other processes to copy the content of the original manuscript in batches. The approved printing plate is transferred to the substrate through the printing roller and special ink. [0003] The surface area of ​​the printing rubber roller is lost due to the deglazing of the printing roller. At the same time, the hardness of the rubber roller becomes larger and the elasticity decreases. Although this phenomenon is inevitable, do not think hastily that the rubber roller has aged and lost its printing function. , Some residual impurities accumulate on the rubber surface of the rubber roller, some of which can be cleaned with water or solv...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a press roller device of a printing machine to solve the problem that impurities accumulated on the rubber surface of the rubber roller mentioned in the above background technology will cause the surface of the rubber roller to lose its microporosity and cause glazing, which will eventually cause serious damage to the printing. big hazard problem
