Description

Technical Field

[0002] With the rapid development of the manufacturing industry, screen printing, as a common printing technology, has also been widely used. Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the image part of the screen printing plate can pass through the ink, while the mesh holes of the non-image part cannot pass through the ink. When printing, pour ink at one end of the screen printing plate, use a scraper to apply pressure to the ink part on the screen printing plate, and move at a constant speed toward the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh holes of the image part to the substrate by the scraper.

[0003] The existing screen printing ink mechanism (for example, the authorization announcement number is: CN 221022850U, and the name is: a screen printing ink control device) stores ink in the first ink barrel, and the ink is transported to the printing plate through the conveying module.
