Description

Technical Field

[0001] The present application relates to the field of screen printing technology, and in particular to a steel plate screen. Background Art

[0002] Silk screen printing, also known as screen printing, refers to using a silk screen as a base and making a screen with images through a photosensitive plate-making method. Silk screen printing consists of five major elements: screen, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the image part of the screen can pass the ink, while the mesh holes of the non-image part cannot pass the ink.

[0003] In the related art, the screen includes a screen frame, a polyester mesh, hot melt adhesive and a silk screen. The silk screen is located at the center of the screen frame, the polyester mesh is fixed on the screen frame at the peripheral side of the silk screen, the silk screen and the polyester mesh are fixed by hot melt adhesive, and a plate film for forming a pattern is arranged on the silk screen; when printing, ink slurry is added to the silk screen, and then the silk screen is pressed down by a scraper to make the silk screen stick to the workpiece, and then the ink slurry is scraped along the plane of the silk screen to the other side, so that the ink slurry is printed on the workpiece through the plate to form a pattern.

[0004] It is found in actual use that since the silk screen is a mesh woven from metal wires, during the printing process, the scraper will continuously rub the metal wires in the mesh part of the silk screen, causing the metal wires to wear and break, thus affecting normal printing work. Summary of the invention

[0005] In order to prevent the metal wires of the screen from breaking, the present application provides a steel plate screen, which can effectively increase the service life.

[0006] The steel plate provided in this application adopts the following technical solution:

[0007] A steel plate screen comprises a screen frame, a screen cloth and a screen plate, wherein the screen cloth is fixed on the screen frame, the screen plate is located in the middle of the screen cloth, and a plurality of printing holes for pigments to pass through are provided on the screen plate at positions corresponding to patterns.

[0008] By adopting the above technical solution, the traditional silk screen is changed into a screen plate, and printing holes are opened on the screen plate corresponding to the shape of the pattern to be printed. The printing holes replace the mesh of the silk screen, so as to meet the normal printing needs; during the printing process, the surface of the screen plate is smooth, and the friction and wear between the scraper and the screen plate is small, which can effectively improve the overall service life.

[0009] Optionally, the mesh plate is configured as a tungsten steel plate or a stainless steel plate.

[0010] By adopting the above technical solution, the mesh plate is set to a tungsten steel plate or a stainless steel plate. The tungsten steel plate and the stainless steel plate have high wear resistance and toughness, which meet the requirements for the wire mesh.

[0011] Optionally, the mesh plate and the mesh cloth are connected by hot melt adhesive.

[0012] By adopting the above technical solution, the mesh plate and the mesh cloth are connected by hot melt adhesive. The hot melt adhesive has low cost, high connection reliability, and certain elasticity, which can effectively improve the connection strength between the mesh plate and the mesh cloth.

[0013] Optionally, a plurality of reinforcement holes are opened on the peripheral side of the mesh plate, and the hot melt adhesive is infiltrated into the reinforcement holes.

[0014] By adopting the above technical solution, reinforcement holes are opened on the peripheral side of the mesh plate. When the mesh plate and the mesh cloth are connected, the hot melt adhesive can penetrate into the reinforcement holes, thereby effectively improving the connection strength between the mesh plate and the mesh cloth.

[0015] Optionally, the mesh is configured as a polyester mesh.

[0016] By adopting the above technical solution, the mesh cloth is made of polyester mesh, which has better elasticity.

[0017] Optionally, a reinforcement strip for enhancing the connection strength is pasted at the connection between the mesh cloth and the mesh frame.

[0018] By adopting the above technical solution, a reinforcement strip is pasted at the connection between the mesh cloth and the mesh frame, and the reinforcement strip can improve the connection strength between the mesh cloth and the mesh frame.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. By replacing the traditional silk screen with a stencil, printing holes are opened on the stencil corresponding to the shape of the pattern to be printed, and the mesh of the silk screen is replaced by the printing holes, so as to meet the normal printing needs; during the printing process, the surface of the stencil is flat, and the friction and wear between the scraper and the stencil is small, which can effectively improve the overall service life;

[0021] 2. By opening reinforcement holes on the side of the mesh, hot melt adhesive can penetrate into the reinforcement holes when connecting the mesh and the mesh, thereby effectively improving the connection strength between the mesh and the mesh;

[0022] 3. By pasting a reinforcement strip at the connection between the mesh and the mesh frame, the reinforcement strip can improve the connection strength between the mesh and the mesh frame. BRIEF DESCRIPTION OF THE DRAWINGS
