[0002] 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 the ink, while the mesh holes of the non-image part cannot pass the ink. When printing, pour ink at one end of the screen printing plate, use a scraper to apply a certain 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. At present, the screen printing machine often installs the screen printing plate through bolts, which is inconvenient to disassemble and replace the screen printing plate according to the needs of couplet printing. Therefore, a couplet screen printing machine that is convenient for replacing the screen printing plate is needed.
