A Locking and Adjusting Mechanism for Plate Cylinder of Flexo Printing Machine

Abstract

The invention discloses a locking and adjustment mechanism for a plate roller of a flexography printing machine. The mechanism comprises a pair of fixation disks which are disposed on two ends of the plate roller of the flexography printing machine, a horizontal beam, a pair of locking mechanism and a horizontal adjustment mechanism used for left and right adjustment of the plate roller of the flexography printing machine, wherein a clamping hole is formed in the outer side face of each fixation disk; two ends of the horizontal beam can be installed on wall plates located at two ends of an Anilox roller and an impression roller through left-right moving, a placement groove is formed in the upper surface of the horizontal beam, and clamping grooves used to clamp the fixation disks are formed in bosses located at two ends of the installation groove; each locking mechanism is composed of a fixation base which is located on a fixation wall plate, a compression air cylinder which is installed on the fixation base, a hook spindle connected to the compression air cylinder and a locking hook connected to the hook spindle; and the horizontal adjustment mechanism comprises a connection shaft which is connected to the horizontal beam, a horizontal adjustment handle which is disposed on the other end of the connecting shaft as well as a horizontal adjustment base plate which is installed on the wall plate in a vertically sliding manner and located on the left side of the horizontal adjustment handle. The mechanism disclosed by the invention has the advantages that the Anilox roller and the impression roller can be rapidly positioned and locked by the flexography plate roller, and a horizontal (axial-direction) adjustment function of the flexography plate roller can be implemented.

Description

Technical field [0001] The invention relates to a locking and adjusting mechanism, in particular to a locking and adjusting mechanism for a plate roller of a flexographic printing machine. Background technique [0002] See figure 1 with figure 2 As shown, one of the most popular flexographic printing mechanisms at present has a structure that uses a cam to quickly position the flexographic printing plate roller. In this mechanism, left and right fixed plates 20 are designed at both ends of the flexographic plate roller 10. The outer diameter is strictly equal to the outer diameter of the flexographic plate roller; the wall plates 80 at both ends of the anilox roller 60 and the embossing roller 70 are designed with the convex size and the outer diameter of the anilox roller and the embossing roller The left cam 90 and the right cam 100 are exactly the same, so that when the flexographic plate roller is quickly fixed in the "pit" formed by the left and right cams with the fixed di...

AI Technical Summary

Problems solved by technology

[0003] There is no device for locking the anilox roller and the embossing roller in the existing cam quick positioning flexo printing roller, which is easy to produce errors in the production process due to the effect of external force during use; in addition, the flexographic printing machine is Overall adjustment is required for horizontal (axial) adjustment, which has low working efficiency and is inconvenient to use
