Printing pressure adjusting mechanism of flexo printing machine

Abstract

The invention relates to a printing pressure adjusting mechanism of a flexo printing machine. The printing pressure adjusting mechanism comprises a plate roller, a first connecting shaft, fixed discs,an anilox roller and a printing roller, wherein the fixed discs are arranged on two ends of the plate roller; the first connecting shaft is connected with the plate roller and the fixed discs; the fixed discs are pressed on a supporting base; a sliding piece is arranged on the supporting base and is in sliding connection with a fixing rod; an elastic piece sleeves the fixed rod and is connected with the sliding piece; a connecting piece is arranged on each fixed disc and is connected with the movable piece; a fixed cover is connected with two fixed plates; a threaded rod is vertically arranged, rotationally connected with the fixed cover and in threaded connection with the movable piece; a coarse adjustment gear is horizontally arranged on the threaded rod; a first rotating part is connected with the coarse adjustment gear; a fine adjustment gear is horizontally arranged on a second rotating part and is in engaged transmission connection with the coarse adjustment gear; and the aniloxroller and the printing roller are positioned below the plate roller. The printing pressure adjusting mechanism is easy to operate, the printing pressure of the flexo printing machine can be adjustedand controlled conveniently, time and labor are saved in the adjusting process, the adjusting process is more stable, and the printing pressure is adjusted more precisely.

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
