Description

Technical Field

[0001] The utility model relates to a structure of a printing mesh cloth, in particular to a structure of a monofilament diaphragm composite mesh cloth which combines a monofilament diaphragm with a mesh cloth made of another material. Background Art

[0002] In existing composite printing screen structures, a smaller mesh of a first material is placed in the middle of a larger mesh of a second material. The two meshes are then joined together using methods such as heat pressing. This technique creates a composite edge where the two meshes overlap. A bonding material is then applied to the composite edge, securing the bonding material and the two meshes together through heat pressing.

[0003] In the above technology, both meshes are made of warp and weft yarns woven crosswise. During the hot pressing process, the bonding material will melt and pass through the cross holes of the warp and weft yarns of the two meshes, and finally fix the two meshes together.

[0004] However, the above technology is only applicable to meshes woven by cross-weaving of warp and weft yarns, because only such mesh structures have holes for the bonding material to pass through and bond. When the mesh does not have cross-weft and warp yarn holes, it is not conducive to making a composite printing mesh. Utility Model Content

[0005] [New Issues to be Solved]

[0006] As can be seen from the above-mentioned prior art, the current composite mesh structure is not suitable for meshes that do not include holes formed by cross-weaving of warp and weft yarns. Therefore, it is necessary to provide a new composite mesh structure that is suitable for meshes that do not include holes formed by cross-weaving of warp and weft yarns.

[0009] Furthermore, the monofilament membrane composite mesh structure of the present invention further includes multiple strengthening membrane layers, which include multiple strengthening holes.

The bonding membrane layers pass through the holes and the strengthening holes and simultaneously fix the strengthening membrane layers together.

[0039] The following is a more detailed description of the embodiments of the present invention with reference to the accompanying drawings and element symbols, so that those skilled in the art can implement the embodiments accordingly after studying this specification.

[0040] Figure 11 is a schematic diagram illustrating a monofilament membrane composite mesh structure according to an embodiment of the present invention; Figure 2 A schematic diagram for explaining the present invention 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 membrane composite mesh structure is provided, comprising: a mesh 10 of a first material, a monofilament membrane 20 of a second material, and a plurality of bonding membrane layers 30. The first material mesh 10 comprises a plurality of warp threads and a plurality of weft threads (not shown in the figures), which are cross-woven with each other. In other words, the first material mesh 10 is a large-area mesh described in the prior art. In one embodiment of the present invention, the plurality of warp threads and the plurality of weft threads comprised by the first material mesh 10 are made of terylene. In other embodiments of the present invention, the plurality of warp threads and the plurality of weft threads may be made of metal.

[0041] The second material monofilament membrane 20 includes a plurality of yarns 201 and a polymer film layer 203. The yarns 201 are disposed in the polymer film layer 203, and the polymer film layer 203 includes a plurality of holes 2011. The holes 2011 are disposed on opposite sides of the polymer film layer 203, such as the left and right sides or the top and bottom sides of the polymer film layer 203. The holes 2011 do not include any yarns 201 or polymer film layer 203. The yarns 201 all extend in the same direction and are parallel to each other. For example, the yarns 201 all extend in the warp direction and are parallel to each other, or the yarns 201 all extend in the weft direction and are parallel to each other. In other words, the second material monofilament membrane 20 is composed of only a single type of yarn 201, and the yarns 201 are fixed by the polymer film layer 203. Therefore, the second material monofilament membrane 20 does not include any holes that intersect the warp and weft yarns, and is not suitable for traditional composite mesh structures. Meanwhile, the second material monofilament membrane 20 is a small-area mesh as described in the prior art. In one embodiment of the present invention, the yarn 201 can be made of metal. Furthermore, the yarn 201 can be bonded and secured to the polymer membrane 203 through physical or thermal compression. Furthermore, the polymer membrane 203 can be made of ET, PI, PU, ​​PVC, PP, PTFE, PMMA, PS, or a synthetic polymer.

[0042] Furthermore, a plurality of bonding membrane layers 30 are disposed on opposite sides of the first material mesh 10 and the second material monofilament membrane 20. In other words, the first material mesh 10 and the second material monofilament membrane 20 are disposed between the bonding membrane layers 30. In addition, in one embodiment of the present invention, the bonding membrane layer 30 can be made of PE or other materials.

[0043] In the present invention, the first material mesh 10 and the second material monofilament diaphragm 20 will partially overlap, and the overlapping part is the composite edge S. The hole 2011 is located on the second material monofilament diaphragm 20 at the overlapping part with the first material mesh 10. The bonding film layer 30 will clamp the overlapping part of the first material mesh 10 and the second material monofilament diaphragm 20, and the bonding film layer 30 will pass through the hole 2011 and fix them together. Therefore, in the present invention, although the second material monofilament membrane 20 does not include any holes where the warp and weft yarns intersect, due to the characteristics of the second material monofilament membrane 20, holes 2011 can be directly formed in the polymer film layer 203 using a laser process. In this way, the bonding membrane layer 30 disposed on opposite sides of the first material mesh 10 and the second material monofilament membrane 20 can pass through the holes 2011 during the heat pressing process, so that the bonding membrane layers 30 on the upper and lower sides are fused and fixed to each other, and finally the first material mesh 10 and the second material monofilament membrane 20 are bonded and fixed to each other. In addition, in one embodiment of the present invention, the shape of the hole 2011 can be square, circular, elliptical, diamond, or other geometric shapes.

[0044] Figure 3 This is a schematic diagram for illustrating the cross-sectional structure of another embodiment of the present invention. Figure 3 In another embodiment of the present invention, the monofilament membrane composite mesh structure further includes multiple reinforcing membrane layers 40, each including multiple reinforcing holes 401. The reinforcing membrane layers 40 are disposed within the holes 2011, and the bonding membrane layer 30 passes through the holes 2011 and the reinforcing holes 401, simultaneously securing the reinforcing membrane layer 40. In this embodiment, when the bonding membrane layer 30 enters the holes 2011, it simultaneously passes through the reinforcing holes 401 and secures the reinforcing membrane layer 40 together. Due to the high hardness of the reinforcing membrane layer 40, the strength of the composite edge S can be further enhanced. The reinforcing membrane layer 40 can be made of, for example, PET, metal, or other high-hardness materials. Furthermore, in this embodiment, the shape of the holes 2011 can be square, circular, elliptical, diamond, or other geometric shapes, and the shape of the reinforcing holes 401 can correspond to the shape of the holes 2011 to achieve optimal bonding strength. In other embodiments, the shape of the holes 2011 can differ from the shape of the reinforcing holes 401.

[0045] Figure 4 This is a schematic diagram for illustrating the cross-sectional structure of another embodiment of the present invention. Figure 4In another embodiment of the present invention, the monofilament membrane composite mesh structure further includes multiple reinforcing membrane layers 40. In this embodiment, the reinforcing membrane layer 40 is a sheet-like embodiment and is disposed between the bonding membrane layer 30 and the holes 2011. The reinforcing membrane layer 40 includes reinforcing holes 401. The bonding membrane layer 30 also passes through the holes 2011 and the reinforcing holes 401, thereby securing the reinforcing membrane layer 40. Similarly, in this embodiment, the sheet-like reinforcing membrane layer 40 is disposed within the composite edge S. The reinforcing membrane layer 40 has a higher hardness, thereby further enhancing the strength of the composite edge S. The reinforcing membrane layer 40 is made of, for example, PET, metal, or other high-hardness materials. Furthermore, in this embodiment, the shape of the holes 2011 can be square, circular, oval, diamond, or other geometric shapes, and the shape of the reinforcing holes 401 can correspond to the shape of the holes 2011 to achieve optimal bonding strength. In other embodiments, the shape of the holes 2011 can differ from the shape of the reinforcing holes 401. Furthermore, in this embodiment, the size of the strengthening hole 401 is consistent with the size of the hole 2011. Figure 4 As shown, in other embodiments, the size of the strengthening hole 401 can be larger or smaller than the size of the hole 2011 according to actual use, and multiple strengthening holes 401 can be set on a strengthening film layer 40, and the size of the strengthening hole 401 can be adjusted according to the number of strengthening holes 401.

[0046] It should be understood that although Figure 4 The middle strengthening film layer 40 is disposed between the top bonding film layer 30 and the hole 2011, but the strengthening film layer 40 can also be adjusted to be disposed between the bottom bonding film layer 30 and the hole 2011, or the strengthening film layer 40 can be disposed between both the top and bottom bonding film layers 30 and the hole 2011 to improve the strength of the composite edge S.

[0047] Figure 5 This is a schematic diagram for illustrating the cross-sectional structure of another embodiment of the present invention. Figure 5 In another embodiment of the present invention, the strengthening film layer 40 is also a sheet-shaped embodiment and is disposed between the bonding film layer 30 and the hole 2011. A portion 403 of the strengthening film layer 40 passes through the hole 2011, and the portion 403 passing through the hole 2011 also includes strengthening holes 401. In this embodiment, a portion 403 of the strengthening film layer 40 passes through the hole 2011 to enhance the bonding strength between the polymer film layer 203, the bonding film layer 30, and the strengthening film layer 40.

[0048] Figure 6 This is a schematic diagram for explaining the structure of a monofilament membrane composite mesh fabric according to another embodiment of the present invention. Figure 6In another embodiment of the present invention, the polymer film layer 203 includes a plurality of holes 2011, and the holes 2011 are arranged around the polymer film layer 203, that is, on the four sides of the polymer film layer 203, so as to further improve the bonding strength between the first material mesh 10 and the second material monofilament membrane 20.

[0049] As can be seen from the above disclosure, the present invention provides a monofilament membrane composite mesh structure. This monofilament membrane composite mesh structure has the following advantages: 1. It can be applied to monofilament membranes that do not include intersecting holes for warp and weft yarns. Holes can be provided in the polymer film layer of the second monofilament membrane material, allowing a bonding film layer to pass through the holes to secure the first mesh material and the second monofilament membrane material together. 2. A reinforcing film layer can be further provided to enhance the strength of the composite edge.
