Description

Technical Field

[0001] The utility model relates to printing-related fields, in particular to a printing grid frame. Background Art

[0002] Screen printing refers to the use of a silk screen as a base, and through the photosensitive platemaking method, to make a silk screen printing plate with images and texts. Silk screen printing consists of five major elements: silk screen printing 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 printing plate can pass the ink, while the mesh holes of the non-graphic part cannot pass the ink.

[0003] The Chinese patent with the patent number CN219236480U discloses "A Printing Grid", in which the first nut is installed on the upper side of the circular hole, and the clamping screw is threadedly connected in the first nut to complete the threaded connection between the clamping screw and the frame. There is no need to open a screw hole on the frame to match the clamping screw, which is conducive to reducing the wall thickness of the frame, reducing the production cost of the frame, and achieving the purpose of green printing. One end of the clamping screw is fixed in the outer tube, and then the inner tube sleeved on the clamping screw is inserted in the outer tube. At this time, the outer tube and the inner tube jointly play the role of hiding the clamping screw, preventing ink from randomly adhering to the surface of the clamping screw, and avoiding the situation where the clamping screw is blocked;
