plate-making machine (ctp) into plate press roller mechanism

Abstract

The invention discloses a plate-feeding press wheel mechanism of a direct plate-making machine (CTP). A rocker arm is also rotated on the support shaft, the first end of the rocker arm is located below the limit block, and the limit block is equipped with an adjusting bolt whose lower end is on the upper surface of the first end of the rocker arm. The two ends are located under the pressure plate, and a compression spring is provided between the pressure plate and the upper surface of the second end of the rocker arm, and a pressure wheel device is installed on the second end of the rocker arm; the lifting of the rocker arm can be adjusted by adjusting the adjusting bolt on the limit block. Up and down, so as to drive the pressure roller installed on the rocker arm to increase or decrease the pressure between it and the plate. Due to the existence of the compression spring between the rocker arm and the platen, there can be an appropriate pre-tightening force between the pressure roller and the plate, so that it is no longer necessary to adjust the pressure of the pressure roller due to changes in the thickness of the plate, making the process Version stability has been improved.

Description

technical field [0001] The invention relates to a plate-feeding pinch wheel mechanism. Background technique [0002] The plate-to-plate machine (CTP) plate-feeding pinch mechanism is a very important mechanism in the technical field of plate-to-plate machines, and it can solve the stability problem of CTP plate-feeding. [0003] In the modern printing industry, in the face of printing requirements in different fields, the size requirements for printing plates are becoming more and more diverse. The thickness of different types of printing plates sometimes varies greatly. Therefore, in the plate making process, the stability of the plate feed has a very important impact on the quality of the direct plate-making machine plate. The consistency of the printing plate produced can reduce unnecessary debugging in the later printing, save printing time and ensure the quality of printed matter. At present, it is very difficult to adjust the pressure wheel mechanism of the tradition...

AI Technical Summary

Problems solved by technology

At present, it is very difficult to adjust the pressure roller mechanism of the traditional direct plate-making machine, and it is difficult to ensure the consistency of the pressure rollers on both sides, which directly affects the efficiency of the plate-making machine and the quality of plate-making

In daily use, due to long-term use, the pressure on both sides of the pressure rollers is inconsistent, and it is very difficult for users to adjust
