Printer impressing mechanism for rapidly dismounting and replacing press roll

Abstract

The invention discloses a printer impressing mechanism for rapidly dismounting and replacing a press roll. Clamp springs are fixed at the end parts of third rotating shafts, connecting rods penetratethrough the clamp springs, the connecting rods are inserted into connecting holes, the connecting rods and the connecting holes are in interference fit, the fixing is firm, the connecting rods are taken out, a printing press roll body can be replaced quickly, a bolt fastening mode in the prior art is abandoned, and the disassembly and assembly efficiency is improved. An adjusting mechanism is arranged, an air pressure rod drives a limiting rod to rotate by driving an air cylinder, the limiting rod drives a lower pressing rod to move up and down, a traction plate moves up and down, a support plate drives the printing press roll to move up and down, the downward pressing strength between the printing press roll and a packaging film is adjusted, the printing effect is further adjusted, the printing flatness, the printing precision and the quality of printed product patterns are improved, the integrated operation of feeding, printing and receiving is realized, and the production efficiencyis improved.

Description

technical field [0001] The invention relates to the field of printing of packaging films, in particular to an embossing mechanism of a printing machine that can quickly disassemble and replace pressing rollers. Background technique [0002] A machine for printing text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Printing onto paper or other substrate to reproduce the same print as the printing plate. [0003] Most of the printing press rollers in the existing embossing mechanism for packaging film printing are fastened by bolts. When the press roller is damaged or the embossing effect i...

AI Technical Summary

Problems solved by technology

[0003] Most of the printing press rollers in the existing embossing mechanism for packaging film printing are fastened by bolts. When the press roller is damaged or the embossing effect is not good, it needs to be replaced, but it is very difficult to disassemble. Inconvenient, increased work intensity

[0004] At the same time, the distance between the existing printing press roller and the packaging film to be printed is fixed, the pressing force between the printing press roller and the packaging film is fixed, and the distance between the printing press roller and the packaging film cannot be adjusted. Long-term work will affect the printing effect, and the printing flatness, printing accuracy and quality of the printed pattern cannot be guaranteed
