Description

Technical Field

[0001] This application relates to the field of horticultural pest control technology, and in particular to an insect-proof net. Background Technology

[0002] Insect-proof netting is an essential part of modern agriculture. It can be installed at the doors, windows, and ventilation openings of greenhouse buildings to effectively prevent harmful insects from entering. Currently, existing insect-proof netting is typically woven on a loom, consisting of warp and weft yarns with ventilation holes between them. These holes allow for air exchange between the greenhouse interior and the outside air, ensuring proper air circulation.

[0003] Existing insect nets are manufactured by cutting large pieces into smaller ones. The edges of the cut nets are uneven and prone to burrs, which affects the safety and comfort of operators when installing and using the nets. Utility Model Content

[0004] To address the problem of burrs appearing on the edges of existing insect-proof nets, this application provides an insect-proof net.

[0005] On the one hand, the insect-proof net provided in this application adopts the following technical solution:

[0006] An insect-proof net, comprising:

[0007] Multiple warp yarns and multiple weft yarns, each warp yarn extending along a first direction and each weft yarn extending along a second direction, both warp and weft yarns are monofilament yarns, the warp and weft yarns are interwoven into a mesh, the insect net has a first edge and a second edge extending along the first direction;

[0008] Edge sealing, which covers the end of the weft yarn, includes a first edge sealing and a second edge sealing. The first edge sealing is located at a first edge, and one end of the weft yarn is bonded to the first edge sealing. The second edge sealing is located at a second edge, and the other end of the weft yarn is bonded to the second edge sealing.

[0009] By adopting the above technical solution, the problem of burrs on the edges after traditional cutting is solved by sealing and bonding the weft yarn ends. This makes the edges of the insect net smoother, improving installation safety and user comfort. At the same time, the monofilament weaving structure of the warp and weft yarns maintains air permeability, preventing the deterioration of the greenhouse environment.

[0010] In some implementations, each edge banding is bonded to at least one warp yarn.

[0011] By adopting the above technical solution, the edge banding is bonded to at least one warp yarn, which enhances the bonding strength between the edge banding and the net body, prevents the edge banding from falling off, and improves the durability and overall structural stability of the insect-proof net.

[0012] In some embodiments, the edge sealing includes a first sealing layer, a connecting layer, and a second sealing layer. The first sealing layer is connected to one side of the connecting layer, and the second sealing layer is connected to the other side of the connecting layer. The first sealing layer and the second sealing layer can be folded relative to each other to cover the end of the weft yarn.

[0013] By adopting the above technical solution, the layered folding design of the edge sealing (first sealing layer, connecting layer, and second sealing layer) achieves tight wrapping of the weft yarn ends, adapts to different yarn thicknesses, ensures the sealing and consistency of the edge sealing, and further reduces the risk of burrs.

[0014] In some implementations, the ends of each weft yarn are fused together.

[0015] By adopting the above technical solution, the weft yarn ends are melt-bonded, eliminating the possibility of loose yarn ends, enhancing the connection strength between weft yarns, preventing edge loosening, and extending the service life of the insect-proof net.

[0016] In some embodiments, a vent is formed between the warp and weft yarns, the vent diameter being 0.15–1 mm, and the diameters of the warp and weft yarns being 0.15–0.25 mm.

[0017] By adopting the above technical solution, and by limiting the pore size and yarn diameter, the insect-proof and air-permeable performance is balanced. This effectively blocks the invasion of pests while ensuring air circulation inside and outside the greenhouse, thus avoiding excessive humidity or carbon dioxide accumulation.

[0018] In some implementations, the length of the edge banding in the second direction is W mm, satisfying: 3 < W < 4.

[0019] By adopting the above technical solution and limiting the length of the edge sealing in the second direction, the coverage of the edge sealing is optimized, which not only fully protects the ends of the weft yarn, but also avoids affecting the flexibility and breathability of the insect-proof net due to excessive edge sealing.

[0020] In some embodiments, the ends of each weft yarn are fused together to form a connection area, and the area of ​​the connection area between two adjacent weft yarns accounts for 90% to 100% of the area of ​​the vent hole.

[0021] By adopting the above technical solution, the connecting area accounts for 90% to 100% of the area of ​​the ventilation holes, almost completely sealing the gap at the ends of the weft yarns, preventing the edges from loosening, and at the same time maintaining the firmness of the sealing edge through melt bonding, ensuring the integrity of the edge of the insect-proof net.

[0022] In some embodiments, multiple indentations are provided on the edge banding, with each indentation spaced apart along a first direction.

[0023] By adopting the above technical solutions, the indentation design on the edge sealing makes the pressure distribution more uniform during the rolling process, improving the edge sealing processing accuracy and bonding strength; the indentation may also enhance the tear resistance of the edge sealing and improve the mechanical properties of the insect-proof net edge.

[0024] In some implementations, the spacing between two adjacent indentations is 2 mm.

[0025] By adopting the above technical solution and controlling the spacing of the indentations, the edge sealing can achieve a better bonding effect, thereby minimizing the problem of edge sealing coming undone.

[0026] In some embodiments, the length of the indentation in the second direction is L mm, satisfying: 1 < L < 3.

[0027] By adopting the above technical solution and limiting the length of the indentation, a better edge sealing effect can be achieved, and the connection effect between the edge sealing and the warp and weft yarns can be enhanced.

[0028] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting the edge sealing to cover the weft yarn ends and bonding them for fixation, the problem of burrs on the edges after traditional cutting is solved, making the edges of the insect net smoother, improving installation safety and user comfort;

[0030] 2. The edge banding is bonded to at least one warp yarn, which enhances the bonding strength between the edge banding and the net body, prevents the edge banding from falling off, and improves the durability and overall structural stability of the insect net;

[0031] 3. The layered folding design of the edge sealing achieves tight wrapping of the weft yarn ends, adapts to different yarn thicknesses, ensures the sealing and consistency of the edge sealing, and further reduces the risk of burrs. Attached Figure Description

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0039] To more clearly describe the technical solution, we define as follows: Figure 1 The first direction X, the second direction Z, and the third direction Y shown in the diagram are intersecting. Preferably, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. It can be understood that the first direction X, the second direction Y, and the third direction Z are not absolutely perpendicular to each other, but can be at a certain angle.

[0040] Reference Figure 1 This application provides an insect-proof net, comprising multiple warp yarns 1 extending along a first direction X and multiple weft yarns 2 extending along a second direction Y. The warp yarns 1 and weft yarns 2 are interlaced and bonded to form a mesh structure. The mesh structure has a size of 7-20 cm in the second direction Y. Air vents 4 are formed between the warp yarns 1 and weft yarns 2 to allow air circulation between the inside and outside of the insect-proof net. In this embodiment, both the warp yarns 1 and weft yarns 2 are monofilament yarns, which can achieve good air permeability, thereby minimizing the problems of excessively high temperature and humidity or excessively low carbon dioxide content in the greenhouse. In other embodiments, the warp yarns 1 and weft yarns 2 can be double-filament yarns, which is not limited here.

[0041] Specifically, the insect-proof net also includes an edge seal 3. In some embodiments, the edge seal 3 can be a film or a webbing. In this embodiment, the edge seal 3 includes a first edge seal 31 and a second edge seal 32. The insect-proof net has a first edge and a second edge extending along a first direction X. The first edge seal 31 is disposed on the first edge, and one end of the weft yarn 2 is bonded to the first edge seal 31. The second edge seal 32 is disposed on the second edge, and the other end of the weft yarn 2 is bonded to the second edge seal 32.

[0042] By setting the edge sealing 3, which covers the ends of the weft yarn 2, the problem of burrs on the edge of the insect net after traditional cutting can be solved. The edge sealing 3 can make the edge of the insect net smoother, improving installation safety and user comfort.

[0043] Furthermore, each edge band 3 is bonded to at least one warp yarn 1. By bonding the edge band 3 to at least one warp yarn 1, the bonding strength between the edge band 3 and the warp yarn 1 and weft yarn 2 is enhanced, which helps to prevent the edge band 3 from falling off and improves the durability and overall structural stability of the insect net.

[0044] Reference Figure 2 and Figure 3 In this embodiment, the edge sealing 3 includes an integrally formed first sealing layer 33, a connecting layer 34, and a second sealing layer 35. The first sealing layer 33 is disposed on one side of the connecting layer 34 along a third direction Z, and the second sealing layer 35 is disposed on the other side of the connecting layer 34 along a third direction Z. The first sealing layer 33 and the second sealing layer 35 can be folded relative to each other to cover the end of the weft yarn 2. The layered folding design of the edge sealing 3 achieves tight coverage of the end of the weft yarn 2, adapts to different yarn thicknesses, ensures the sealing and consistency of the edge of the edge sealing 3, and further reduces the risk of burrs.

[0045] In some embodiments, the ends of each weft yarn 2 are fused together. This fusion bonding eliminates the possibility of loose yarn ends, enhances the connection strength between the weft yarns 2, prevents edge loosening, and thus extends the service life of the insect-proof net. The fusion bonding of the ends of each weft yarn 2 forms a connection area 7, which occupies 90% to 100% of the area of ​​the ventilation holes 4 between adjacent weft yarns 2. The connection area 7, occupying 90% to 100% of the ventilation hole area 4, almost completely seals the gap at the ends of the weft yarns 2, preventing edge loosening, while simultaneously maintaining the firmness of the edge seal 3 through fusion bonding, ensuring the integrity of the insect-proof net's edges.

[0046] Furthermore, ventilation holes 4 are formed between the warp yarn 1 and the weft yarn 2. The diameter of the ventilation holes 4 is 0.15–1 mm, and the diameters of the warp yarn 1 and the weft yarn 2 are 0.15–0.25 mm. By limiting the diameter of the ventilation holes 4 and the diameter of the yarns, the insect-proofing and ventilation performance are balanced. This effectively blocks the invasion of pests while ensuring air circulation inside and outside the greenhouse, avoiding excessive humidity or carbon dioxide accumulation. The length of the sealing edge 3 in the second direction Y is W mm, satisfying: 3 < W < 4. By limiting the length of the sealing edge 3 in the second direction Y, the coverage of the sealing edge 3 is optimized, which fully protects the ends of the weft yarn 2 while avoiding the impact of excessive length of the sealing edge 3 on the flexibility and breathability of the insect-proof net.

[0047] In some embodiments, the edge banding 3 is provided with multiple indentations 5, each indentation 5 being spaced apart along the first direction X. The indentations 5 on the edge banding 3 are designed to bond the warp yarns 1 and weft yarns 2 to the edge banding 3 as a single unit, preventing the insect-proof net from fraying, ensuring more uniform pressure distribution during rolling, and improving the processing accuracy and bonding strength of the edge banding 3. The indentations 5 may also enhance the tear resistance of the edge banding 3 and improve the mechanical properties of the insect-proof net's edge. In this embodiment, the distance between two adjacent indentations 5 in the first direction X is 2 mm, and the length of each indentation 5 in the second direction Y is L mm, satisfying: 1 < L < 3, and the length of the indentation 5 in the second direction Y is less than the length of the edge banding 3 in the second direction Y.

[0048] The insect-proof net provided in this application first weaves the warp yarns 1 and weft yarns 2 into a mesh structure. Then, a cutting device cuts the mesh structure, and a folding device folds the edge sealing 3 so that the edge sealing covers the first and second edges of the mesh structure. An ultrasonic welding device welds the edge sealing 3 to the warp yarns 1 and weft yarns 2, and a rolling device rolls the first and second edges. In this embodiment, the cutting device can be a mechanical cutting machine or a laser cutting machine, etc., which is existing technology and is not limited here. The ultrasonic device is specifically an ultrasonic welding machine. The ultrasonic device transmits energy through high-frequency vibration waves, causing the sealing layer, warp yarns 1, and weft yarns 2 to generate heat through friction under pressure, achieving molecular layer fusion. The ultrasonic device is existing technology and will not be described in detail here.

[0049] Specifically, in this embodiment, the roller pressing equipment includes a pressure roller and a drive source, which is connected to the pressure roller via a drive mechanism. The drive source is specifically a drive motor in this embodiment. The surface of the pressure roller is provided with multiple first pressure teeth and multiple second pressure teeth. Both the first and second pressure teeth are arranged circumferentially along the pressure roller and are respectively located at both ends of the roller. The first pressure teeth correspond to the first edge, and the second pressure teeth correspond to the second edge. By setting the first and second pressure teeth, indentations 5 can be formed on the sealing layer after roller pressing, achieving better adhesion strength between the sealing layer and the weft yarn 2, and improving the structural strength of the sealing edge 3.

[0050] The implementation principle of this application embodiment is as follows: First, multiple warp yarns 1 and weft yarns 2 are woven into a mesh structure. Then, the mesh structure is cut to the required size. Then, the first edge sealing 31 is folded along the first edge and wrapped around one end of the weft yarn 2, and the second edge sealing 32 is folded along the second edge and wrapped around the other end of the weft yarn 2. Ultrasonic welding is used to fuse the edge sealing 3 with the mesh structure, eliminating the burrs generated after the mesh structure is cut, thereby ensuring the comfort of the operator when installing and using the insect net.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
