Fixing device for screen outer frame

Abstract

The invention discloses a fixing device for a screen outer frame. The fixing device comprises two groups of positioning mechanisms, the positioning mechanisms are oppositely arranged on the two sides of a printing machine, each positioning mechanism comprises a fixing strip, one side of each fixing strip is provided with a fixing assembly, and the fixing assemblies are arranged on the opposite sides of the two groups of positioning mechanisms. Each fixing assembly comprises a clamping groove fixing piece and a sliding rail fixing piece, the clamping groove fixing pieces and the sliding rail fixing pieces are fixed to the two ends of the fixing strips separately, the sliding rail fixing pieces are horizontally arranged in the extending direction of the fixing strips, and the clamping groove fixing pieces are connected with positioning columns of the screen outer frame in a buckled mode. The sliding rail fixing pieces are connected with the positioning columns of the screen outer frame in a sliding mode. According to the fixing device for the screen outer frame, different screens can be fixed in a matched mode, and people can conveniently and better install the screens.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a fixing device for a screen frame. Background technique [0002] Printing refers to the process of dyes or paints forming patterns on fabrics. Printing machines are mechanical equipment used for batch printing. Most of the existing printing processes use printing machines to replace traditional manual reinforcement, which solves the problem of high labor intensity in manual printing. Low efficiency and non-uniform printing, using mechanical equipment for printing reduces labor intensity, increases labor efficiency, makes printing uniform, and improves printing quality. [0003] However, the existing printing machine needs to fix the screen on the printing machine before printing, and then fix the screen. The structure of the existing screen is as follows: figure 1 , there will be positioning columns 2 on the opposite sides of the screen plate 1, and the number of pos...

AI Technical Summary

Problems solved by technology

When there is a deviation, it is easy to cause the positioning pins on the screen to be unable to be accurately aligned with the positioning holes on the fixing device, and when using different screens, there may also be a gap between the two positioning pins on the screen. Differences, resulting in the need to replace or adjust the fixing device on the printing machine, which brings inconvenience to people's installation and use
