Abstract
Description
Technical Field
[0001] The utility model relates to a printing screen, in particular to a monofilament printing screen comprising a monofilament printing mesh and a monofilament printing composite screen. Background Art
[0002] In existing printing screen technology, the commonly used weaving process involves cross-weaving warp and weft yarns. For example, the warp yarns are first stretched, passed through a reed, and then the weft yarns are woven to form a printing mesh. Finally, the printing mesh is stretched and fixed to a screen frame to form a printing screen. However, when printing on a printing screen made of a cross-woven printing mesh with warp and weft yarns, ink often gets stuck at the intersections of the warp and weft yarns, ultimately reducing the quality of the printed image. Utility Model Content
[0003] [New Issues to be Solved]
[0004] As can be seen from the above-mentioned prior art, printing ink is usually stuck at the intersection of warp and weft yarns. Therefore, how to prevent the generation of intersection of warp and weft yarns in the printing screen has always been a problem that needs to be solved in the printing screen technology.
[0005] [Technical means to solve the problem]
[0006] A monofilament printing screen comprises: a screen frame; a monofilament printing mesh fixed to the screen frame, the monofilament printing mesh comprising a plurality of yarns and a polymer film layer, the yarns being arranged in the polymer film layer and all extending in the same direction and parallel to each other; and at least one opening pattern formed on the monofilament printing screen; wherein the monofilament printing screen comprises a scraper surface and a printing surface.
[0007] Preferably, the yarns are a plurality of warp threads or a plurality of weft threads of the monofilament printing mesh.
[0008] Preferably, the warp threads are metal warp threads, and the weft threads are metal weft threads.
[0009] Preferably, the yarns do not comprise a concave-convex structure.
[0010] Furthermore, the present invention also provides a monofilament printing composite screen, comprising: a screen frame; a first material net fixed on the screen frame; a monofilament printing mesh fixed on the first material net, the monofilament printing mesh comprising a plurality of yarns and a polymer film layer, the yarns being arranged in the polymer film layer, and the yarns all extending in the same direction and parallel to each other; and at least one opening pattern formed on the monofilament printing mesh; wherein the monofilament printing mesh comprises a scraper surface and a printing surface.
[0011] Preferably, the yarns are a plurality of warp threads or a plurality of weft threads of the monofilament printing composite screen.
[0012] Preferably, the warp threads are metal warp threads, and the weft threads are metal weft threads.
[0013] Preferably, the yarns do not comprise a concave-convex structure.
[0014] [New effects]
[0015] The utility model provides a monofilament printing screen and a monofilament printing composite screen. The screen structure comprises a monofilament printing mesh made of a single yarn, and further comprises at least one opening pattern formed in the monofilament printing mesh.

[0031] The following describes the embodiments of the present invention in more detail with reference to the accompanying drawings and element symbols, so that those skilled in the art can implement the invention accordingly after studying the specification.
[0032] Figure 1 FIG. 1 is a schematic diagram illustrating the structure of a monofilament printing screen according to an embodiment of the present invention. Figure 2 A schematic diagram to illustrate Figure 1 Please refer to the AA cross-section structure in Figure 1 and Figure 2 In one embodiment of the present invention, a monofilament printing screen is provided. The monofilament printing screen includes a screen frame 10, a monofilament printing mesh 20, and at least one opening pattern 30. The monofilament printing mesh 20 is fixed to the screen frame 10 and includes a plurality of yarns 201 and a polymer film layer 203. The yarns 201 are disposed in the polymer film layer 203 and all extend in the same direction and are parallel to each other. The monofilament printing mesh 20 includes a scraper surface S10 and a printing surface S20.
[0033] It is worth noting that because the opening pattern 30 is formed on the monofilament printing mesh 20, the opening pattern 30 only includes one type of yarn 201. In the present invention, no additional processes are required to remove the other yarns in the monofilament printing mesh 20. This avoids the problem of uneven rolling marks on one yarn after removing the other yarns, which occurs in the prior art. Furthermore, because the monofilament printing mesh 20 is composed of a single yarn 201, the yarn 201 in the opening pattern 30 is a single, smooth yarn, unlike the wavy pattern formed by the cross-weaving of two yarns in the prior art. That is, the yarn 201 does not include any concave or convex structures, and the smoothness of the yarn 201 prevents ink from being stuck during printing.
[0034] In this way, after the ink falls from the scraper surface S10, it can flow smoothly from the printing surface S20 without any obstruction, thereby printing a more complete and conductive pattern and improving the printing yield. In addition, in one embodiment of the present invention, the yarn 201 can be a non-woven fabric or a commonly used yarn material. In other embodiments of the present invention, in order to improve the durability of the monofilament printing screen, the yarn 201 can be made of metal.
[0035] Figure 3 FIG1 is a schematic diagram illustrating the structure of a monofilament printing screen according to another embodiment of the present invention; Figure 4 A schematic diagram to illustrate Figure 3 Please refer to the A'-A' cross-sectional structure in Figure 3 and Figure 4 In another embodiment of the present invention, another monofilament printing screen is provided, Figure 1 and Figure 2 The structural difference of the monofilament printing screen shown is that the weaving direction of the yarn 201 in the monofilament printing mesh 20 is different. Figure 1 The yarn 201 shown is woven in the weft direction. Figure 3 The yarn 201 shown is warp-woven, and similarly, the warp-woven yarn 201 can also be made of non-woven fabric or commonly used yarn materials. In other embodiments of the present invention, in order to improve the durability of the monofilament printing screen, the warp-woven yarn 201 can be made of metal. It is worth mentioning that in this embodiment, the opening pattern 30 can be arranged between two adjacent yarns 201 to achieve the effect of completely avoiding the yarns 201 in the opening pattern 30. In other embodiments of the present invention, the opening pattern 30 can include the yarn 201 (not shown in the figure). Similarly, because the yarn 201 is a flat yarn without any concave-convex structure, it can also prevent ink from being stuck during printing.
[0036] In other words, the yarns 201 in the monofilament printing mesh 20 of the present invention can be woven in either the weft or warp direction. Regardless of the weft or warp weave, the opening pattern 30 does not contain any intersecting knots of warp and weft yarns, nor does it contain both warp and weft yarns. No additional processing is required to remove other yarns. Consequently, after the ink falls from the squeegee surface S10, it can flow smoothly from the printing surface S20 without any obstruction, resulting in a more complete and conductive pattern and improved printing yield.
[0037] Figure 5 This is a schematic diagram for explaining the structure of a single-filament printing composite screen in another embodiment of the present invention. Figure 5 In another embodiment of the present invention, a composite monofilament printing screen is provided. The composite monofilament printing screen includes a screen frame 10, a first material mesh 40, a monofilament printing mesh 20, and at least one opening pattern 30. The first material mesh 40 is fixed to the screen frame 10 and can be a terylene mesh, a polymer film mesh similar to the monofilament printing mesh 20, a metal mesh, or a composite mesh combining multiple of the above meshes.
[0038] The monofilament printing mesh 20 is fixed on the first material mesh 40. The monofilament printing mesh 20 includes a plurality of yarns 201 and a polymer film layer 203. The yarns 201 are arranged in the polymer film layer 203, and the yarns 201 all extend in the same direction and are parallel to each other. The monofilament printing mesh 20 also includes a scraper surface and a printing surface.
[0039] The opening pattern 30 is also formed on the monofilament printing mesh 20. In this embodiment, the first material mesh 40 is combined with the monofilament printing mesh 20, so the area of the monofilament printing mesh 20 can be reduced, thereby reducing the production cost of the monofilament printing composite screen. Moreover, because the monofilament printing composite screen also uses the monofilament printing mesh 20, it also has the advantages of the monofilament printing mesh of the present invention. It should be understood that although Figure 5 The figure shows the yarn 201 woven in the weft direction, but the yarn 201 can also be woven in the warp direction, and the yarn 201 woven in the weft direction or the warp direction can also be non-woven fabric, commonly used yarn material or metal material.
[0040] Furthermore, in the above-described embodiment of the present invention, the polymer film layer 203 may be made of polytetramethylene terephthalate, PET, PE, PI, PU, PVC, PP, PTFE, PMMA, PS, or other polymer materials. Furthermore, the yarn 201 and the polymer film layer 203 may be fixedly bonded by thermal compression, physical compression using a compression device, or other compression methods.
[0041] As can be seen from the above disclosure of the present invention, the present invention provides a monofilament printing screen and a monofilament printing composite screen. The monofilament printing screen and the monofilament printing composite screen of the present invention have the following functions and advantages: 1. A monofilament printing screen comprising only a single type of yarn is used in the monofilament printing screen and the printing composite screen, and at least one opening pattern is further provided on the monofilament printing screen. In this way, the opening pattern does not include any cross-knots of warp and weft yarns, and no other processes are required to remove other yarns. This allows for more complete and conductive graphics to be printed, and improves printing yield. 2. Because the monofilament printing screen is composed of a single yarn, the yarn in the opening pattern is a smooth yarn, unlike the wavy yarn formed by the cross-weaving of two types of yarn in the prior art. That is, the yarn does not include any concave and convex structures, and the smooth yarn can prevent ink from being stuck during printing.
