Intermittent silk-screen printing device

Abstract

The invention discloses an intermittent silk-screen printing device which comprises a seat body and a conveying belt. A printing chamber is formed above the seat body, the conveying belt penetrates through the printing chamber, conveying rollers are arranged at two ends of the conveying belt, the conveying belt consists of a climbing section and a descending section, and a supporting roller is arranged at the separated position of the climbing section and the descending section. Symmetrically-arranged fixing seats are installed on the inner wall of the printing chamber and are located above the conveying belt, silk screens are installed in the fixing seats, printing portions are arranged at the center of the silk screens and located above the supporting roller, a guide rail is arranged in the top face of the printing chamber and provided with a scraper device. The conveying belt penetrates through the printing chamber of the device, so that conveying and processing of boards are facilitated, four board fixing devices are arranged in the printing chamber, conveyed boards are positioned and fixed, printing effect is improved, intermittent printing effect is achieved, printing efficiency is improved, and higher benefit is brought to enterprises.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an intermittent screen printing device. Background technique [0002] Screen printing, together with offset printing, embossing, and gravure printing, is called the four major printing methods; screen printing is composed of five major elements, namely, screen printing plate, scraping scraper, ink, printing table and substrate, screen printing The basic principle of printing is: use the basic principle of the screen printing plate for the graphic part of the mesh to penetrate the ink, and the non-graphic part of the mesh to be impermeable to the ink. The ink part on the screen printing plate exerts a certain pressure, and at the same time moves towards the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh of the graphic part to the substrate by the scraper. [0003] In the existing technology, the printing process of the printing machine is rou...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the printing process of the printing machine is roughly as follows: after the paper moves to the bottom of the screen, the scraper lands on the screen on the surface of the paper to be printed, and the scraper starts to squeegee and print. The finished paper leaves the bottom of the screen, and the screen needs reciprocating translational movement during the scraper coating process. During the reciprocating motion of the screen, the printing machine can only perform a single printing on the paper to be printed, resulting in low efficiency and increased labor. question
