AI Technical Summary

Technical Problem

Existing plate printing alignment auxiliary devices are prone to plate displacement when they need to be fixed after positioning, which affects printing quality and efficiency.

Method used

A printing alignment mark identification frame was designed, which adopts four sets of symmetrically arranged inclined slots and slider structures. Combined with a bidirectional hydraulic cylinder to drive the slider movement, the four sets of clamping blocks move synchronously closer or further away. With the help of L-shaped clamping blocks, the plate is clamped from two vertical directions. The movement accuracy and stability are improved by dustproof belts and ceramic coating.

Benefits of technology

It enables rapid and accurate positioning and fixing of the board material, avoids offset after positioning, improves printing alignment accuracy and stability, is suitable for boards of different thicknesses, and enhances printing quality and efficiency.

Abstract

This utility model discloses a printing alignment mark identification frame, belonging to the technical field of printing equipment. It includes a base, with an alignment seat on the top surface of the base. The top surface of the alignment seat has four sets of inclined grooves, symmetrically arranged about the axial and radial axes of the alignment seat. Each inclined groove has a first slider sliding on it. A clamping block, L-shaped with a 90-degree included angle, is mounted on the top surface of each first slider. The alignment seat has an internal cavity, which is connected to the four inclined grooves. A bidirectional hydraulic cylinder with a rod extension is installed within the cavity. A pair of sliding strips slides within the cavity. A fixing block connects the pair of sliding strips to the two telescopic ends of the bidirectional hydraulic cylinder. A transverse groove is formed along the long side of each sliding strip, and a pair of second sliders slides within the transverse groove. The first and second sliders are connected. This technical solution, through the use of four sets of clamping blocks that move synchronously closer or further apart, can fix and position the printing plate to be printed, thereby ensuring the printing quality of the plate.
