Description

Technical Field

[0001] This utility model relates to the field of polyester screen printing technology, specifically to a polyester screen printing plate. Background Technology

[0002] A polyester screen printing stencil is a tool commonly used in screen printing. It is made from polyester chemicals through processes such as drawing and spinning, then woven or knitted into a mesh structure. The stencil is then made using a photosensitive material and a photographic plate-making method. It belongs to screen printing and consists of three parts: a frame, a mesh, and a photosensitive emulsion. The frame holds the mesh in place. During use, the polyester screen is placed above and fixed on the printing equipment, and a reciprocating squeegee transfers the pattern from the polyester screen onto the material.

[0003] However, before installing the polyester screen onto the printing equipment, the relative positions of the squeegee, screen, and printing plate must be repeatedly adjusted to ensure that the squeegee can move smoothly back and forth above the screen. Because the width of the screen frame at both ends is fixed and cannot be adjusted according to equipment requirements, the clamps lack flexibility when holding the screen. This structural limitation can easily obstruct the squeegee's movement, affecting the stability and efficiency of the printing process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a polyester screen with adjustable clamping positions at both ends.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polyester screen, comprising a screen frame, a screen connected within the screen frame, and a printing area located within the screen. End plates are slidably connected to the outer sides of both ends of the screen frame. The end plates are L-shaped and threaded with a plurality of first threaded rods at the top of the end plates. One end of each of the first threaded rods passes through the end plate and abuts against the outer wall of the screen frame.

[0006] Furthermore, two symmetrically arranged sliders are fixedly connected to the inner wall of the end plate, and the outer walls at both ends of the mesh frame are provided with sliding grooves, in which the sliders are slidably connected.

[0007] Furthermore, the inner wall of the end plate is fixedly connected to two symmetrically arranged L-shaped rods, which are slidably connected to the mesh frame.

[0008] Furthermore, a support structure is also connected to the back of the mesh frame. The support structure includes two support rods. Two storage slots are provided on the back of the mesh frame. The support rods are hinged to the storage slots. An integral rod is fixedly connected between the two support rods and is embedded in the mesh frame.

[0009] Furthermore, one of the support rods has a second threaded rod threadedly connected to its outer wall, and the second threaded rod passes through the support rod and is threadedly connected to the mesh frame.

[0010] Furthermore, a stop block is fixedly connected to the outer wall of the end of the storage slot away from the integrated rod, and the stop block abuts against the outer wall of the support rod.

[0011] Furthermore, both the outer ends of the first and second threaded rods are connected to anti-slip rotating bosses.

[0012] Furthermore, the side of the screen located in the printing area is also covered with a TPI functional film.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features end plates at both ends of the wire mesh frame, allowing the end plates to slide at the ends of the frame, thus enabling adjustable end distance and improving the flexibility of the frame during clamping. Two support rods and an integrated rod, when unfolded, form a U-shaped structure that supports the wire mesh frame when placed on the ground, facilitating its placement. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4As shown, a polyester screen includes a frame 1, a screen 2 connected within the frame 1, and a printing area 3 located within the screen 2. End plates 4 are slidably connected to the outer sides of both ends of the frame 1. The end plates 4 are L-shaped and have multiple first threaded rods 5 threadedly connected to the top of the end plates 4. One end of each first threaded rod 5 passes through the end plate 4 and abuts against the outer wall of the frame 1.

[0022] like Figures 1 to 4 As shown, when the polyester screen of this utility model is in use, the clamp and the end plate 4 can be clamped together when the screen frame 1 is clamped with the equipment, so that the screen frame 1 is installed. The first threaded rod 5 can be unscrewed so that the bottom surface of the first threaded rod 5 is separated from the top surface of the screen frame 1. At this time, the end plate 4 can be pushed so that it slides on the top surface of the screen frame 1, so that the clamped position of the end of the screen frame 1 can be adjusted backward. That is, the width of the screen frame 1 can be adjusted when it is clamped. This setting can improve the flexibility of the screen frame 1 when clamped.

[0023] By setting end plates 4 at both ends of the wire mesh frame 1, the end plates 4 can slide at the ends of the wire mesh frame 1, thereby making the end distance of the wire mesh frame 1 adjustable and improving the flexibility of the wire mesh frame 1 when clamping.

[0024] like Figure 2 and Figure 3 As shown, two symmetrically arranged sliders 10 are fixedly connected to the inner wall of the end plate 4, and grooves 6 are opened on the outer walls of both ends of the mesh frame 1, with the sliders 10 slidingly connected within the grooves 6.

[0025] Specifically, when the end plate 4 slides, it drives the slider 10 to slide in the groove 6. This setting can make the sliding of the end plate 4 stable.

[0026] like Figure 2 and Figure 3 As shown, the inner wall of the end plate 4 is fixedly connected with two symmetrically arranged L-shaped rods 11, and the L-shaped rods 11 are slidably connected to the mesh frame 1.

[0027] Specifically, when the end plate 4 slides, it drives the two L-shaped rods 11 to move simultaneously. By using the L-shaped rods 11, the end plate 4 can be restricted by the bottom L-shaped rods 11 and can only move laterally for adjustment. This ensures that the end plate 4 will not have displacement problems when it moves laterally for adjustment.

[0028] In addition, the L-shaped rod 11 can also serve as a handle to push the end plate 4, making the movement and adjustment of the end plate 4 easy to operate.

[0029] like Figure 2 and Figure 3As shown, a support structure is also connected to the back of the mesh frame 1. The support structure includes support rods 7, and there are two support rods 7. Two storage slots 12 are opened on the back of the mesh frame 1. The support rods 7 are hinged to the storage slots 12. An integral rod 8 is fixedly connected between the two support rods 7 and is embedded in the mesh frame 1.

[0030] Specifically, when the wire mesh frame 1 is removed and not in use for the time being, the support rod 7 can be rotated to hinge the end of the support rod 7 in the storage groove 12, and at the same time, the integrated rod 8 will rotate out of the wire mesh frame 1. The two support rods 7 and the integrated rod 8 form a U-shaped arrangement, which allows the wire mesh frame 1 to be placed on the ground.

[0031] The two support rods 7 and the integrated rod 8 form a U-shaped structure when unfolded, which supports the mesh frame 1 when it is placed on the ground, thus facilitating the placement of the mesh frame 1.

[0032] like Figure 2 and Figure 3 As shown, a second threaded rod 9 is threadedly connected to the outer wall of one of the support rods 7. The second threaded rod 9 passes through the support rod 7 and is threadedly connected to the mesh frame 1.

[0033] Specifically, when the support rod 7 is stored in the storage slot 12, in order to ensure the normal use of the polyester screen, the second threaded rod 9 can be rotated to connect with the support rod 7 and the screen frame 1. In this way, the second threaded rod 9 is used to lock the support rod 7 to the outer wall of the screen frame 1, ensuring the stability of the support rod 7.

[0034] like Figure 3 and Figure 4 As shown, a stop block 13 is fixedly connected to the outer wall of the end of the storage slot 12 away from the integrated rod 8, and the stop block 13 abuts against the outer wall of the support rod 7. When the support rod 7 rotates to a certain angle, it will be blocked by the stop block 13, so that the support rod 7 will not continue to unfold outward, so that the unfolded support rod 7 and the mesh frame 1 can form a certain unfolding angle, making the support more stable.

[0035] like Figure 2 and Figure 3 As shown, both the outer ends of the first threaded rod 5 and the second threaded rod 9 are connected to anti-slip rotating bosses. These anti-slip rotating bosses facilitate the rotation of the first threaded rod 5 and the second threaded rod 9.

[0036] Furthermore, the side of the screen 2 located in the printing area 3 is also covered with a TPI functional film. When using the polyester screen of this invention, a TPI functional film of appropriate thickness (usually 40%-50% of the thickness of the screen 2) needs to be matched according to the required polyester screen thickness for printing. Then, the TPI functional film is hot-pressed onto the printing surface of the polyester screen (i.e., the side located in the printing area 3) using a dedicated hot-pressing device (pressing temperature 160-200°C, pressure 0.2-0.4MPa, time 10-30 minutes). Next, photosensitive emulsion is applied to the printing surface and ink surface of the TPI functional film, dried, exposed, and developed. Then, PI etching solution is evenly applied from the printing surface to the area to be printed, heated to 85°C for 1-2 minutes, and then the etched TPI functional film is removed from the printing surface using a high-pressure water gun. Finally, the screen is dried and ready for printing. Replacing traditional capillary film with TPI functional film not only ensures printing precision but also leverages the high abrasion resistance and solvent resistance of TPI functional film to significantly increase the number of printing passes, reduce the number of screen changes, and improve printing efficiency.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
