Improvement on transmission mechanism of silk printing machine

Abstract

The invention relates to the technical field of silk printing equipment, and in particular relates to an improvement on a transmission mechanism of a silk printing machine. The transmission mechanism comprises a speed reducer, swinging arms, supporting rods, sliding plates and a fixed frame, wherein an output shaft of the speed reducer is provided with the swinging arms which are hinged with the supporting rods; two groups of the swinging arms, the supporting rods and the sliding plates are arranged; the output shaft of the speed reducer is provided with a left output end and a right output end which are respectively provided with the left swinging arm and the right swinging arm; the other ends of the left swinging arm and the right swinging arm are respectively connected with the left supporting rod and the right supporting rod; the other ends of the left supporting rod and the right supporting rod are hinged on the left sliding plate and the right sliding plate; the fixed frame comprises a left frame body and a right frame body; guide rails arranged on the left frame body or the right frame; and the left sliding plate and the right sliding plate are limited to slide on sliding rails. By adoption of the transmission mechanism with double supporting rods, the printing accuracy is high, the printing color difference is less, the printing speed is high, the positioning is accurate, the supporting force is stable, the mechanical operation is more stable, and the service life of the silk printing machine can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of screen printing equipment, in particular to an improvement of a transmission mechanism of a screen printing machine. Background technique [0002] A screen printing machine is a machine for printing text and images. Modern screen printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass, and ceramics to reproduce the same print as the printing plate. [0003] At present, most screen printing machines use a motor to drive the reducer...

AI Technical Summary

Problems solved by technology

Because the reducer is driven by a rocker arm and a support rod, this kind of transmission mechanism is generally set in the middle of the screen printing machine. During the working process of the screen printing machine, a rod is supported, which will easily cause the two sides to be non-parallel and the transmission is not stable enough.

Moreover, in the printing process, the screen printing machine with a single-bar structure has a large printing color difference and the accuracy is not high enough.

In the process of single pole rising, due to insufficient supporting force, the printing speed is slower and the efficiency is lower
