A new composite screen structure

Abstract

This utility model relates to the field of screen printing technology and discloses a novel composite screen printing structure, including an installation frame. A polyester mesh is adhered to the upper end of the installation frame, a composite fabric is adhered to the upper end of the polyester mesh, and a steel wire mesh is adhered to the upper end of the composite fabric. In this utility model, when the composite screen printing structure is used and edge sealing is completed, the snap-fit ​​design of the positioning block and positioning groove ensures precise positioning of the edge sealing frame during installation, allowing the edge sealing frame to accurately align with the corresponding position, thereby ensuring the accuracy and stability of the overall structure. At this time, the limiting block is compressed by the force driving the limiting spring. When the limiting block coincides with the limiting hole, the limiting spring releases its force, causing the limiting block to rebound, thus firmly snapping it into the limiting hole, thereby limiting the edge sealing frame. This ensures that the edge sealing frame maintains a stable position after installation, thereby reducing the stress on the edge sealing material and extending its service life.

Description

Technical Field

[0001] The utility model relates to the technical field of screen printing plates, in particular to a novel composite screen printing plate structure. Background Art

[0002] As we all know, composite screen printing is an advanced screen printing technology that combines the characteristics of multiple screens to improve printing quality and efficiency. This technology is often used for printing tasks that require high precision and complex patterns, such as electronic circuit boards, solar panels, and fine graphics. In composite screen printing, two or more screens are usually superimposed on each other, and each screen is responsible for printing a different color or layer. These screens are precisely aligned with each other through special alignment technology to ensure the accuracy and consistency of the printed pattern. This method of multi-screen superposition allows the printing of multiple colors or layers in one printing stroke, thereby reducing the need for multiple printing processes and improving production efficiency. Composite screen printing can also optimize the transfer of ink and the resolution of the image through different screen materials, making the details of the printed product clearer and the colors richer. In addition, this technology also helps to reduce errors and waste in the printing process and improve the overall production cost-effectiveness.

[0003] However, traditional composite screen structures usually use special edge banding tapes or edge banding strips, which are manually pasted on the edge of the screen to prevent ink leakage. Long-term use and environmental conditions may cause their viscosity to decrease, which may result in the durability of the edge banding tapes or edge banding strips being limited, or even falling off or damaged. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a novel composite screen structure is proposed. When the composite screen structure is used, after the edge sealing is completed, the clamping design of the positioning block and the positioning groove can ensure the precise positioning of the sealing frame during the installation process, so that the sealing frame can be accurately aligned with the corresponding position, thereby ensuring the accuracy and stability of the overall structure. At this time, the limit block is compressed by the limit spring driven by the force. When the limit block coincides with the limit hole, the limit spring releases the force to drive the limit block to rebound, so that it is firmly clamped in the limit hole, thereby limiting the sealing frame, which can ensure that the sealing frame maintains a stable position after installation, thereby reducing the force on the edge sealing material, thereby extending its service life.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel composite screen structure comprises an installation frame, a polyester mesh is adhered to the upper end of the installation frame, a composite cloth is adhered to the upper end of the polyester mesh, a wire mesh is adhered to the upper end of the composite cloth, a sealing frame is arranged at the upper end of the installation frame, a plurality of positioning blocks are fixedly connected to the edge of the lower end of the sealing frame, a plurality of positioning grooves are provided at the edge of the upper surface of the installation frame, a limiting groove is provided on the side of the outer wall of the positioning block away from the center of the installation frame, a limiting spring is fixedly connected to the side adjacent to the limiting groove, and a limiting block is fixedly connected to the side of the limiting spring away from the center of the installation frame.

[0007] Through the above technical scheme, compared with the existing composite screen structure, when the composite screen structure is used, the polyester mesh cloth, composite cloth and steel wire mesh cloth are stacked layer by layer to enhance the overall strength and stability of the screen, so that it can withstand greater printing pressure and longer use. The composite cloth is used as a transition layer between the steel wire mesh cloth and the polyester mesh cloth to balance the characteristics of the two different materials and improve the overall performance and durability of the screen. The composite of steel wire and nylon mesh not only ensures the strength and wear resistance of the mesh, but also improves the permeability of the ink through the softness of the nylon mesh. It is suitable for high-precision printing and has high practical performance.

[0008] Furthermore, the positioning blocks are respectively engaged with the interior of the positioning grooves;

[0009] Through the above technical solution, the positioning blocks are respectively engaged with the inner part of the positioning grooves, so that the sealing frame can be positioned easily.

[0010] Furthermore, the inner wall of the positioning groove on one side away from the center of the installation frame is provided with a limiting hole, and the limiting blocks are respectively engaged with the limiting holes;

[0011] Through the above technical solution, the limiting blocks are respectively engaged with the limiting holes, so as to facilitate the limiting of the sealing frame.

[0012] Further, the composite cloth is a region where the steel wire mesh cloth and the polyester mesh cloth are composited together;

[0013] Through the above technical scheme, the composite cloth is used for the area where the steel wire mesh cloth and the polyester mesh cloth are composited together. The steel wire mesh cloth provides strength and wear resistance, while the polyester mesh cloth provides good flexibility and ease of use. The composite of the two materials can combine their advantages to make the composite cloth more durable and able to withstand long-term use and repeated cleaning.

[0014] Furthermore, the steel wire mesh is made of a composite of steel wire and nylon mesh;

[0015] Through the above technical solution, the steel wire provides higher strength and wear resistance, and can withstand greater printing pressure and repeated use, while the nylon mesh has good flexibility and tensile resistance. The combination of the two makes the steel wire mesh more durable and can extend the service life of the screen.

At this time, the limit block is compressed by the limit spring driven by the force. When the limit block coincides with the limit hole, the limit spring releases the force to drive the limit block to rebound, so that it is firmly clamped into the limit hole, thereby limiting the sealing frame, which can ensure that the sealing frame maintains a stable position after installation, thereby reducing the force on the edge sealing material, thereby extending its service life.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-5 , an embodiment provided by the utility model:

[0028] A novel composite screen structure comprises an installation frame 1, a polyester mesh cloth 2 is adhered to the upper end of the installation frame 1, a composite cloth 3 is adhered to the upper end of the polyester mesh cloth 2, a steel mesh cloth 4 is adhered to the upper end of the composite cloth 3, a sealing frame 7 is arranged at the upper end of the installation frame 1, a plurality of positioning blocks 8 are fixedly connected to the edge of the lower end of the sealing frame 7, a plurality of positioning grooves 5 are provided at the edge of the upper surface of the installation frame 1, a limiting groove 9 is provided on the side of the outer wall of the positioning block 8 away from the center of the installation frame 1, a limiting spring 10 is fixedly connected to the side adjacent to the limiting groove 9, and a limiting block 11 is fixedly connected to the side of the limiting spring 10 away from the center of the installation frame 1.

[0029] Compared with the existing composite screen structure, when the composite screen structure is used, the polyester mesh cloth 2, the composite cloth 3 and the steel wire mesh cloth 4 are stacked layer by layer to enhance the overall strength and stability of the screen, so that it can withstand greater printing pressure and longer use. The composite cloth 3 is used as a transition layer between the steel wire mesh cloth 4 and the polyester mesh cloth 2 to balance the characteristics of the two different materials and improve the overall performance and durability of the screen. The composite of steel wire and nylon mesh not only ensures the strength and wear resistance of the mesh, but also improves the permeability of the ink through the softness of the nylon mesh. It is suitable for high-precision printing and has high practical performance.

[0030] The positioning blocks 8 are respectively engaged with the inner part of the positioning groove 5, and the positioning blocks 8 are respectively engaged with the inner part of the positioning groove 5 to facilitate positioning of the sealing frame 7. The inner wall of the positioning groove 5 away from the center of the installation frame 1 is provided with a limiting hole 6, and the limiting blocks 11 are respectively engaged with the limiting hole 6, and the limiting blocks 11 are respectively engaged with the limiting hole 6 to facilitate positioning of the sealing frame 7. The composite cloth 3 is an area where the steel wire mesh cloth 4 and the polyester mesh cloth 2 are composited together, and the composite cloth 3 is an area where the steel wire mesh cloth 4 and the polyester mesh cloth 2 are composited together. The steel mesh cloth 4 provides strength and wear resistance, while the polyester mesh cloth 2 provides good flexibility and ease of use. The composite of the two materials can combine their advantages to make the composite cloth 3 more durable and able to withstand long-term use and repeated cleaning. The steel mesh cloth 4 is composited with steel wire and nylon mesh. The steel wire provides higher strength and wear resistance, and can withstand greater printing pressure and repeated use. The nylon mesh has good flexibility and tensile resistance. The combination of the two makes the steel mesh cloth 4 more durable and can extend the service life of the screen.

[0031] Working principle: During the printing process, the ink is evenly applied to the substrate through the image area of ​​the screen. Since the steel wire mesh 4 is made of a composite of steel wire and nylon mesh, it can provide good ink permeability and durability, making the printing process smoother and reducing downtime caused by mesh problems. The design of the composite cloth 3 helps to balance the stress between the steel wire mesh 4 and the polyester mesh 2, so that the screen can adapt to different printing needs and environments. When the edge sealing is completed, the snap-fit ​​design of the positioning block 8 and the positioning groove 5 can ensure the precise positioning of the sealing frame 7 during the installation process, so that the sealing frame 7 can be accurately aligned with the corresponding position, thereby ensuring the accuracy and stability of the overall structure. At this time, the limit block 11 is compressed by the force driving the limit spring 10. When the limit block 11 coincides with the limit hole 6, the limit spring 10 releases the force and drives the limit block 11 to rebound, so that it is firmly snapped into the limit hole 6, and then the sealing frame 7 is limited. It can ensure that the sealing frame 7 maintains a stable position after installation, thereby reducing the force on the edge sealing material, thereby extending its service life.
