Description

Technical Field

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

[0002] Screen printing, also known as silk screen printing, refers to using a silk screen as the plate base and making a screen plate with patterns and texts through a photosensitive plate-making method. Screen printing consists of five major elements: a screen plate, a squeegee, ink, a printing table, and a substrate. The printing is carried out based on the basic principle that the ink can pass through the mesh holes in the graphic part of the screen plate, while the ink cannot pass through the mesh holes in the non-graphic part.

[0003] In the related art, the screen plate includes a screen frame, a polyester screen, hot melt adhesive, and a silk screen. The silk screen is located at the center of the screen frame, the polyester screen is fixed on the screen frame on the periphery of the silk screen, and the silk screen and the polyester screen are fixed through hot melt adhesive. A plate film for forming a pattern is provided on the silk screen. During printing, the ink slurry is added to the silk screen, then the silk screen is pressed down by the squeegee to make the silk screen adhere 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 passes through the plate mold and is printed on the workpiece to form a pattern.

[0004] In actual use, it is found that when making the plate mold, it is necessary to apply emulsion or attach a yellow film on the silk screen to block the mesh holes of the silk screen and leave the mesh holes required for printing the pattern; when leaving the mesh holes required for the pattern, sometimes it is necessary to cut and extract the metal wires at the corresponding positions to obtain the desired pattern. After the metal wires are cut and extracted, the overall structural strength of the silk screen will be reduced, resulting in a reduced service life of the silk screen. Summary of the Invention

[0005] In order to reduce the reduction in strength after the silk screen is drawn, the present application provides an electroforming composite screen plate, which can effectively improve the overall service life.

[0006] The electroforming composite screen plate provided by the present application adopts the following technical solutions:

[0007] An electroforming composite screen plate includes a screen frame, a polyester screen, and a silk screen. The polyester screen is fixed on the screen frame, and the silk screen is located in the middle of the polyester screen; printing holes are provided on the silk screen, and a sealing plate layer is electroformed on the part of the silk screen except the printing holes.

[0008] By adopting the above technical solution, the sealing plate layer is attached to the silk screen through an electroforming process. The sealing plate layer can integrate the metal wires on the silk screen, thereby improving the overall structural strength of the silk screen, preventing the silk screen from reducing its structural strength due to wire drawing, and effectively improving the overall service life.

[0009] Optionally, reinforcing ribs are provided at positions on the silk screen corresponding to the printing holes, and the reinforcing ribs connect the silk screen and the sealing plate layer on both sides.

[0012] By adopting the above technical solution, distributing a plurality of reinforcing ribs along the length direction of the printing holes can effectively improve the structural strength of the wire mesh.

[0013] Optionally, the wire mesh is provided as an integral metal mesh cloth.

[0014] By adopting the above technical solution, setting the wire mesh as an integral metal mesh cloth can save the work of wire drawing during the production of the stencil, facilitate processing, and avoid the defects after wire drawing of the wire mesh.

[0015] Optionally, the wire mesh is connected to the polyester mesh through hot melt adhesive.

[0016] By adopting the above technical solution, the hot melt adhesive has a certain elasticity and can deform with the polyester mesh and the wire mesh, which helps to improve the service life of the screen plate.

[0017] Optionally, a reinforcing strip is pasted at the connection between the polyester mesh and the screen frame.

[0018] By adopting the above technical solution, pasting a reinforcing strip at the connection between the polyester mesh and the screen frame can effectively improve the connection strength between the polyester mesh and the screen frame.

[0020] 1. By attaching a sealing plate layer to the wire mesh through electroforming, the sealing plate layer can integrate the metal wires on the wire mesh, thereby improving the overall structural strength of the wire mesh, preventing the structural strength of the wire mesh from being reduced due to wire drawing, and effectively improving the overall service life;

[0027] The following will further elaborate on this application in conjunction with the attached Figures 1-3 drawings.

[0028] An electroforming composite screen plate disclosed in an embodiment of this application, referring to Figure 1 , includes a frame 1, a polyester mesh 2, a hot melt adhesive 3, and a wire mesh 4. The frame 1 is a rectangular frame, and the polyester mesh 2 is tensioned and fixed on the frame 1; the four sides of the wire mesh 4 are fixed in the middle of the polyester mesh 2 through the hot melt adhesive 3.

[0029] Referring to Figure 1 and Figure 2 , printing holes 41 are opened at positions on the wire mesh 4 corresponding to the pattern to be printed, and a sealing plate layer 42 is fixed at positions on the wire mesh 4 where no printing holes 41 are opened. The sealing plate layer 42 is processed on the wire mesh 4 through an electroforming process. The sealing plate layer 42 is integrated with the wire mesh 4, which can effectively improve the structural strength of the wire mesh 4.

[0030] Reinforcing ribs 43 are electroformed at positions on the wire mesh 4 corresponding to the printing holes 41. A plurality of reinforcing ribs 43 are distributed along the length direction of the printing holes 41. The reinforcing ribs 43 connect the wire mesh 4 and the sealing plate layer 42 on both sides of the printing holes 41, which can effectively improve the structural strength of the wire mesh 4 at the printing holes 41.

[0031] A reinforcing strip 5 is adhesively fixed at the connection between the polyester mesh 2 and the frame 1. The reinforcing strip 5 is a rubber strip in any form, which can effectively strengthen the connection strength between the polyester mesh 2 and the frame 1 and prevent detachment during use.

[0032] Referring to Figure 3 , the wire mesh 4 adopts an integral metal mesh cloth. During the processing, the process of drawing out metal wires can be omitted, reducing the processing difficulty; and the integral metal mesh cloth is integrally formed, with high overall consistency and relatively higher structural strength compared to traditional mesh cloth. Combining with the electroformed sealing plate layer 42 can further improve the overall service life.

[0033] The implementation principle of an electroforming composite screen plate disclosed in an embodiment of the present application is as follows: By electroforming a sealing plate layer 42 on a wire mesh 4, the sealing plate layer 42 is used to replace conventional emulsions and yellow films. The sealing plate layer 42 has higher strength and longer service life than emulsions and yellow films. At the same time, the sealing plate layer 42 is integrated with the wire mesh 4, which can effectively improve the overall structural strength and service life.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
