An inking roller for a printing machine

Abstract

The invention provides an inking roller for a printing machine. The inking roller comprises an outer roller, an inner extrusion mechanism and an inking mechanism. According to the inking roller, the problems that the amount of ink attached to the ink roller at the tail end is reduced due to the action of multiple ink transferring rollers in an existing inking roller in the moving process, so that the printing and dyeing of a printing and dyeing product by the ink roller is influenced, and the phenomenon that the printing product is dark in the front and light in the back can be easily caused, meanwhile, the ink at an inking port can be easily sprayed and dropped in the uniform inking process of the inking roller, so that the printing and dyeing product is scrapped, and meanwhile, the ink coagulation is prone to occur in the inking process of the existing inking roller, and the uniform flowing of the ink is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of ink printing, in particular to an ink form roller for a printing machine. Background technique [0002] Inking rollers are the rollers in a printing press that apply ink to the printing plate. In actual printing, the ink color of the same printed product often appears dark before and then light. In addition to improper process operation and adjustment, this phenomenon is mainly due to the influence of the structure of the cylinder and the arrangement of the ink rollers. [0003] The existing ink form rollers are affected by multiple ink transfer rollers during the movement process, which reduces the amount of ink attached to the end ink form rollers, which affects the printing and dyeing of printed products by the ink form rollers, and easily causes the printed products to appear dark in the front and light in the back; at the same time In the uniform inking process of the existing inking roller, the ink...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing ink form roller is affected by multiple ink transfer rollers during the movement process so that the amount of ink attached to the end ink form roller is reduced, which affects the printing and dyeing of the ink form roller on the printed matter, and it is easy to make the printed product appear dark at the front and shallow at the end At the same time, the existing inking rollers are prone to ink spraying and dripping at the inking port during the uniform inking process, resulting in the scrapping of printed and dyed products; at the same time, the existing inking rollers are prone to ink condensation during the inking process, which affects the uniform flow of ink, etc. question
