Description

Technical Field

[0001] The present application relates to the technical field of screen printing equipment, and in particular to a 3D cover screen printing screen frame. Background Art

[0002] At present, after the 3D cover plate is processed, it is usually screen-printed. Screen printing (abbreviated as silk screen printing) refers to using a silk screen as a base and making a silk screen plate with images through a photosensitive platemaking method. Silk screen printing consists of five major elements: silk screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the graphic part of the silk screen printing plate can pass through the ink, while the mesh holes of the non-graphic part cannot pass through the ink. When printing, pour ink at one end of the silk screen printing plate, use a scraper to apply a certain pressure to the ink part on the silk screen printing plate, and move at a constant speed toward the other end of the silk screen printing plate. During the movement, the ink is squeezed from the mesh holes of the graphic part to the substrate by the scraper. The silk screen printing plate is usually composed of two parts: a silk screen and a silk screen frame. The silk screen is installed on the bottom surface of the silk screen frame.

[0003] After searching, the patent document with authorization announcement number CN206938157U announced a new type of 3D cover plate silk screen frame, including an inner frame with a silk screen window, a silk screen covering the entire silk screen window fixedly set on the bottom surface of the inner frame, a convex strip protruding from the bottom surface of the inner frame body is set at the bottom of the inner frame, and the side of the convex strip is set as a slope, the height of the slope is greater than or equal to the depth of the concave surface of the substrate and the position corresponds to the edge of the substrate, so that the area of ​​the outer convex mesh surface extending into the concave surface of the substrate corresponding to the side of the convex strip is a gentle slope, the screen frame stretches the silk screen into a slope with the same slope through the slope on the convex strip, and uses the slope of the silk screen to shield the edge of the substrate in a non-planar state, so that the scraper can smoothly transition when moving to the edge of the substrate. It is suitable for printing substrates with arc edges on both sides, and is also suitable for printing substrates with arc edges on four sides. It is flexible, convenient and highly adaptable.

[0004] The above-mentioned related schemes are found to still have at least the following deficiencies in actual use: the specifications and dimensions of the 3D cover screen printing frame are fixed, and only one size of screen can be assembled for screen printing. The specifications and dimensions of the screen printing frame cannot be changed and adjusted to suit a variety of screens of different sizes, and the practical performance is poor.

[0005] Therefore, we propose a 3D cover screen printing frame to solve the above problems. Utility Model Content
