Plate roller engagement and disengagement mechanism of flexo-printing machine

Abstract

The invention discloses a plate roller engagement and disengagement mechanism of a flexo-printing machine, and aims to solve the problems of poor plate roller inking and ink accepting uniformity, poorprinting quality and the like due to unstable engagement pressure of plate rollers, impression cylinders and anilox rollers in the prior art. The mechanism is technically characterized by comprisingan impression cylinder in running fit with a rack of the flexo-printing machine, an anilox roller in running fit with a printing unit, lifting devices fixed to two sides of a unit frame of the printing unit, shoulder iron glidingly matched with the unit frame and matched with the driving ends of the lifting devices as well as a plate roller in running fit with the shoulder iron; the plate roller,the impression cylinder and the anilox roller are in the engagement or disengagement state; the mechanism is characterized in that shoulder iron seats matched with the shoulder iron are arranged on two sides of the unit frame; matched parts of the shoulder iron and the shoulder iron seats are corresponding inclined surfaces; the matched parts of the shoulder iron and the shoulder iron seats make contact with each other and are wedged when the plate roller, the impression cylinder and the anilox roller are in the engagement state; and the matched parts of the shoulder iron and the shoulder ironseats are separated from each other when the plate roller, the impression cylinder and the anilox roller are in the disengagement state.

Description

technical field [0001] The invention relates to a working mechanism of printing equipment, in particular to a version roller clutch pressing mechanism of a flexographic printing machine. It is suitable for flexographic printing machines such as satellite flexographic printing machines, stacked flexographic printing machines and unit flexographic printing machines. Background technique [0002] The clutch pressure of the plate roller of the flexographic printing machine refers to that when the flexographic printing machine is performing normal printing, the plate roll is in a state of joint pressure with the impression cylinder and the anilox roller, or is separated from the impression cylinder and the anilox roller. off-pressure state. The plate roller clutch pressure mechanism is generally composed of an impression cylinder that rotates and fits on the frame of the flexographic printing machine, an anilox roller that rotates and fits on the printing unit, lifters that are ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the unstable joint pressure of the plate roller, the impression cylinder and the anilox roller in the clutch press mechanism of the plate roller of the existing flexographic printing machine using a hydraulic lifter or a pneumatic lifter, resulting in inking and inking of the plate roll The poor uniformity of ink receiving affects the problem of poor printing quality. The purpose of the present invention is to provide an improved plate roller clutch and pressure mechanism of a flexographic printing machine, which can overcome the defects of the prior art
