Screen printing plate-making system and method for ensuring film-forming properties

Abstract

The invention discloses a silk-screen printing plate-making system and method for ensuring a film-forming property. The system comprises a box. A first drying chamber, a glue application chamber and a second drying chamber are arranged in the box from top to bottom and communicate mutually through a screen plate conveying channel. An opening for communicating with the first drying chamber is formed in the top end of the box. Two glue application mechanisms arranged symmetrical about a silk-screen plate are arranged in the glue application chamber. A screen plate conveying mechanism is further arranged in the box and used for conveying the silk-screen printing plate which is unglued to the second drying chamber through the screen plate conveying channel from the first drying chamber so as to complete gluing of the first time, and conveying the silk-screen printing plate which is glued to the first drying chamber through the screen plate conveying channel from the second drying chamber so as to complete gluing of the second time. According to the system and the method, the two glue application mechanisms are used for carrying out full-automatic gluing on two faces of the silk-screen printing plate, in the gluing process, air in screen eyes of the silk-screen printing plate can be removed fully, and it is ensured that photo-sensitive glue has the excellent film-forming property.

Description

technical field [0001] The invention belongs to the technical field of screen printing plate making, and in particular relates to a screen printing plate making system and method for ensuring film-forming properties. Background technique [0002] Screen printing refers to using a screen as a plate base and making a screen printing plate with graphics through a photosensitive plate-making method. Screen printing consists of five major elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the graphic part of the screen printing plate can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the ...

AI Technical Summary

Problems solved by technology

[0004] The current screen printing plates are all made manually. When the photosensitive glue is applied manually, the other side is often coated after the coating is completed. This method of gluing is difficult to completely eliminate the air bubbles trapped in the mesh of the screen. , resulting in poor film-forming properties of the photosensitive adhesive, which affects the printing quality of the screen printing plate in the later stage
