Description

Technical Field

[0001] The utility model belongs to the field of printing devices, and in particular relates to a screen printing device for packaging boxes. Background Art

[0002] Screen printing refers to the use of silk screen as a base and the use of photosensitive platemaking methods to make a silk screen plate with images. Silk screen printing consists of five major elements: silk screen plate, scraper, ink, printing table and substrate. Printing is carried out based on the basic principle that the mesh holes of the graphic part of the silk screen plate can pass through the ink, while the mesh holes of the non-graphic part cannot pass through the ink.

[0003] The authorization publication number "CN218054431U" records "a screen printing device, belonging to the printing field, including a workbench, the top of the workbench is connected to two vertical plates, the tops of the two vertical plates are commonly connected to a horizontal plate, a screen plate is arranged between the workbench and the horizontal plate, the screen plate is mounted on a mounting plate, a moving mechanism is arranged on the mounting plate, a scraper is arranged on the moving mechanism, tooth plates are arranged on both sides of the screen plate, the mounting plate is a hollow structure, and the bottom and top of the mounting plate are connected up and down. When installing the screen plate, the screen plate is inserted into the mounting plate. During the movement, the screen plate drives the gears on both sides to rotate through the tooth plates. When the back of the screen plate hits the mounting plate and cannot move, the screen plate is installed. The stability of the gear is increased by the friction assembly. When disassembly is required, the gear is rotated in the opposite direction to move the screen plate out of the mounting plate. This process is simple to operate and convenient for replacing the screen."

[0004] The above patent is simple to operate and convenient for replacing the screen, but it is not easy to disassemble the scraper. After the scraper is used for a long time, a large amount of pigment will adhere to the surface of the scraper, thereby affecting printing. Utility Model Content
