A printing pressure adjustment mechanism for a flexographic printing machine

Abstract

A printing pressure adjustment mechanism for a flexographic printing machine, comprising a plate roller, a first connecting shaft, a fixed plate, an anilox roller and a printing roller; the fixed plate is located at both ends of the plate roller, and the first connecting shaft connects the plate roller and the fixed plate; The fixed plate is pressed on the support base; the sliding piece is arranged on the support base and is slidably connected with the fixed rod; the elastic piece is sleeved on the fixed rod and connected with the sliding piece; the connecting piece is set on the fixed plate and connected with the movable piece; The cover is connected with two fixed plates, the threaded rod is vertically arranged and connected with the fixed cover in rotation, and the threaded rod is threadedly connected with the movable part; the coarse adjustment gear is horizontally arranged on the threaded rod; the first rotating part is connected with the coarse adjustment gear; the fine adjustment gear is arranged horizontally On the second rotating part, it is meshed and connected with the coarse adjustment gear; the anilox roller and the printing roller are located under the plate roller. The invention has simple operation, is convenient to adjust and control the printing pressure of the flexographic printing machine, saves time and labor in the adjustment process, the adjustment process is more stable, and the adjustment of the printing pressure is more accurate.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a printing pressure adjustment mechanism of a flexographic printing machine. Background technique [0002] The flexographic printing machine uses fluid ink with strong fluidity. The ink is transferred to the graphic part of the printing plate by the ink fountain rubber roller and the anilox roller to make it inked, and then the printing pressure is applied by the pressure roller to press the printing plate on the printing plate. The ink is transferred to the substrate, and finally the printing process is completed through the dry surface; the flexographic printing machine has a simple structure, so it is easy to operate, easy to maintain, small imprinting force, low printing cost, and good quality of printed products; flexographic printing machine The printing machine mainly consists of four parts, namely unwinding feeding parts, printing parts, drying parts and rewindi...

AI Technical Summary

Problems solved by technology

[0003] The existing flexographic printing machine is difficult to adjust the printing pressure, and the accuracy of the printing pressure adjustment is low, it is inconvenient to control the adjustment of the printing pressure, the adjustment operation is complicated, and the adjustment process is time-consuming and laborious, which needs to be improved
