Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, specifically to a climbing net for vine crops. Background Technology

[0002] Vining crops, also known as climbing crops, require trellises and netting during their growth process to support the stems and vines so that they can twine and grow upwards.

[0003] Currently, the cultivation of climbing vines has largely abandoned the traditional method of manually stringing climbing wires, and has instead adopted manifold climbing nets, also known as pull nets, which can be mass-produced and quickly laid out. Examples include various forms of climbing nets disclosed in patent documents such as CN108642682A, CN216786375U, CN 115613189 A, CN307998473S, CN307777342S, CN308222001S, and CN308807024S. These pull nets or climbing nets share a common characteristic: they all contain supporting traction wires distributed on the upper and lower sides, which act as a framework when unfolded; and shaped traction wires evenly distributed at certain intervals, bending inwards from the outside of the horizontal traction wires, ultimately forming a three-sided contact and wrapping of the horizontal traction wires, with the upper and lower contact points staggered to form the net surface.

[0004] In existing technologies, the support traction line and the forming traction line are usually fixed at the junction, and the fixing methods vary. Some methods involve direct winding, relying on the fine fibers on the surface of the traction line to intertwine and achieve fixation. This method has poor bonding strength, and the junction is prone to loosening during use, causing the net to knot and become unusable. Other methods use glue, but in assembly line production, the glue needs to dry quickly, which can easily form hard lumps at the bonding points. After the net is rolled up, the bonded area bulges severely, affecting transportation. Still others use an edge-sealing machine to sew and fix the junction of the warp and weft threads. This method has excellent parameters, but it requires specialized edge-sealing equipment and improvements to the entire production process, resulting in higher costs. In addition, the sewing machine edge-sealing can only fix the longitudinal position of the two joints, not the lateral position. When the forming traction line is subjected to lateral force, it will slide left and right along the support traction line. Some solutions use low-melting-point polyester materials for hot-melt bonding, but this has special requirements for the net material, limiting the diversification of net manufacturing.

[0005] In addition, in the use of existing climbing nets, the support guide lines mainly serve a supporting function and are more exposed to the outside. Under the influence of sunlight and rain, they are more prone to oxidation than the mostly formed guide lines covered by climbing plants, resulting in a shorter service life. Summary of the Invention

[0006] The purpose of this utility model is to provide a special climbing net for vine crops. By adding external auxiliary components, a good positioning and stabilizing effect is formed at the intersection of the warp and weft threads in the climbing net, preventing deformation during use and improving its overall strength. In addition, the auxiliary components can also cover the support traction lines that support the entire climbing net to form a weather-resistant protective layer, preventing oxidation and improving the overall service life of the climbing net. At the same time, this application also provides a production method of the above-mentioned climbing net based on the prior art.

[0007] One of the objectives of this utility model is to provide a climbing net specifically for vine crops, comprising a support traction line bearing tensile force as the warp 1 and a forming traction line for the net surface as the weft 2; the weft 2 contacts the warp 1 at specific intervals and in a specific order to form equidistant intersection points and constitute the net surface, characterized in that a sheet-like wrapping material 3 is provided along the side of the warp 1, the contact surface of the wrapping material 3 with the warp 1 is provided with an adhesive layer, and the adhesive layer is bonded to the side of the warp 1, and bent along the bonding line until they are attached, thus wrapping the warp 1 and the intersection of the warp 1 and the weft 2.

[0008] The wrapping material 3 is a continuous sheet-like shape, with the same length as the warp 1. The width of the wrapping material 3 is sufficient to completely wrap the warp 1 and the junction of the warp 1 and the weft 2, and the overlapping parts can be bonded together.

[0009] The package 3 is a flexible material in a continuous sheet shape.

[0010] The longitudinal centerline of the inner side of the adhesive layer on the package 3 coincides with the highest protrusion on the side of the warp line 1 that is attached to it.

[0011] Preferably, the climbing net includes two warp threads 1 and one weft thread 2. The weft thread 2 intersects with the two warp threads 1 at equal intervals in the order of top, outside, bottom and / or bottom, outside, top, forming the net surface.

[0012] Preferably, the climbing net includes two warp lines 1 and two weft lines 2. The weft lines 2 intersect with the two weft lines 2 at equal intervals in the order of top side, outside side, bottom side and / or bottom side, outside side, top side, forming a net surface. The two weft lines 2 intersect at the middle position.

[0013] Preferably, a third meridian 1 is set at the midpoint between two meridians 1 in the climbing net. This third meridian 1 is parallel to the existing meridians 1 and is located between the two latitude lines 2 at the intersection point. A wrapping material 3 of the same length is set on the front and back of the third meridian 1. After compression, the two wrapping materials 3 are aligned and glued together to wrap the intersection point and the two latitude lines 2 within the width range of the wrapping material 3.

[0014] Preferably, the distance between the two outermost meridians 1 is divided into equal parts, and two or more identical meridians 1 parallel to them are set at the division points, forming an intersection with the latitude line 2; at the same time, a wrapping material 3 of the same length is set on the front and back of the newly added meridian 1, and after squeezing, the two wrapping materials 3 are aligned and glued together, and the portion of the meridian 1 and the latitude line 2 intersecting with it within the width of the wrapping material 3 is wrapped in it.

[0015] The second objective of this utility model is to provide a method for producing a climbing net specifically for vine crops, comprising the following steps:

[0016] ① Referring to the production steps recorded in documents such as CN116809817A and CN108642682A, the weft 2 and the warp 1 are respectively laid out and pulled, and the weft 2 is wound and crossed around the plane formed by the two warp 1 to form a mesh, and then the mesh is wound up;

[0017] ② The mesh formed by warp 1 and weft 2 is connected to the inside of the package 3 after being unwound and guided by a drive and guide mechanism. Then the mesh moves synchronously with the package 3.

[0018] ③ During the overall movement of the net surface, the package 3 that has been glued to both sides of the net surface is shaped by external force, and it is gradually bent inward from the foil form and transformed into a semi-closed structure with the inner center line of the package 3 as the axis of symmetry and the warp 1 as a whole and the intersection of the warp 1 and the weft 2 as the contents.

[0019] ④ After the mesh surface and the wrapping material 3 are bent into a semi-closed structure, the wrapping material 3 distributed on the upper and lower sides of the weft thread 2 of the mesh surface is gradually squeezed and finally bonded together through a step-by-step linear pressing process acting on the front and back of the mesh surface, so as to encapsulate the warp thread 1 as a whole and the junction of the warp thread 1 and the weft thread 2 in the wrapping material 3.

[0020] ⑤ Wrap and roll up the climbing net that has been wrapped and pasted on both sides to form a shape.

[0021] Preferably, before the package 3 completely seals and wraps the warp 1 as a whole and the junction of the warp 1 and the weft 2, negative pressure is applied during the gradual compression of the package 3 to ensure that the package 3 is tightly adhered.

[0022] Preferably, in the production method of the climbing net with a third warp 1, the three warp threads 1 need to be unwound and guided at equal intervals at the beginning stage. Then, the weft threads 2 are wrapped and crossed around the plane formed by the three warp threads 1 to form a net surface, and the net surface is rolled up. Then, during the rolling process, the two sides of the net surface are respectively bonded to the inner side of the wrapping material 3 that has been unwound and guided. At the same time, two wrapping materials 3 with opposite inner sides and parallel to the net surface are set up and bonded to the two sides of the intersection of the third warp thread 1 and the weft thread 2. Then, the entire net surface and all the wrapping materials 3 move synchronously and gradually apply force to the wrapping materials 3 to shape them. Among them, the wrapping materials 3 on both sides of the third warp thread 1 need to be linearly pressed step by step, and the wrapping materials 3 on both sides are gradually squeezed and finally glued together, so that the entire third warp thread 1 and the intersection with the weft thread 2 are completely sealed in the wrapping material 3.

[0023] Preferably, for climbing nets with two or more warp threads 1, during the production process, the corresponding number of warp threads 1 need to be unwound and guided at equal intervals at the beginning stage; after the weft threads 2 intersect to form the net surface, the outermost wrapping material 3 adopts the same method as the climbing net with two or three warp threads 1; when wrapping several warp threads 1 inside the net surface, each warp thread 1 corresponds to two wrapping materials 3 with opposite inner sides and parallel to the net surface, and the wrapping material 3 is gradually subjected to force to shape it, so that it is finally attached together, and the corresponding warp thread 1 as a whole and the intersection with the weft thread 2 are completely sealed in the wrapping material 3. Beneficial effects

[0024] This application provides a climbing net specifically for vine crops, whose beneficial effects are mainly reflected in terms of stability, service life, and production method:

[0025] ① By adding sheet-like wrapping material 3, a good positioning and stabilizing effect is formed at the junction of the warp 1 and weft 2 of the climbing net. The adhesive layer of the wrapping material 3 is bonded to the outer side of the weft 2 and folded to prevent the climbing net from deforming during use, improve the overall strength, and avoid problems such as easy loosening at the junction and knotting of the net, which are common in traditional fixing methods.

[0026] ② The sheet-like wrapping material 3 covers the support traction line that supports the entire climbing net, forming a weather-resistant protective layer. This effectively prevents the support traction line from being oxidized under sunlight and rain. Compared with the existing technology where the support traction line is easily oxidized, resulting in a shortened service life, the overall service life of this climbing net is improved.

[0027] ③ The production method is an improvement on existing technology, with relatively reasonable and easy-to-operate steps. During the packaging process of the package 3, the package 3 is formed by external force and linearly pressed step by step. Negative pressure suction can also be used during the extrusion process to ensure tight adhesion. For climbing nets with a third warp 1 or more, there are also corresponding reasonable production steps, and the overall production method has good feasibility. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0037] like Figure 1 and Figure 6 As shown, this embodiment provides a climbing net specifically for vine crops, comprising two warp threads 1 and one weft thread 2. The tensile support thread serves as the warp thread 1, and the forming support thread that shapes the net surface serves as the weft thread 2. The weft thread 2 intersects the two warp threads 1 at equidistant points, forming the net surface, in the order of top, outside, and bottom. A sheet-like covering 3 is provided along the side of the warp thread 1. This covering 3 is a continuous sheet of flexible material, with the same length as the warp thread 1. The width of the covering 3 is sufficient to completely cover the warp thread 1 and the intersection of the warp thread 1 and the weft thread 2, with overlapping portions able to adhere to each other. An adhesive layer is provided on the inner side of the covering 3, which adheres to the side of the warp thread 1 and is bent along the adhesive line until it is fully bonded, thus covering the warp thread 1 and the intersection of the warp thread 1 and the weft thread 2. The longitudinal centerline on the inner side of the adhesive layer of the package 3 coincides with the highest protrusion on the side of the warp line 1 that is attached to it.

[0038] Its production method is as follows:

[0039] ① By releasing and pulling the latitude line 2 and the longitude line 1 respectively, the latitude line 2 is wound and crossed around the plane formed by the two longitude lines 1 to form a net surface, and then the net surface is rolled up.

[0040] ② The mesh formed by warp 1 and weft 2 is connected to the inner side of the unwound and guided package 3 by a drive and guide mechanism. Then the mesh and the package 3 move synchronously.

[0041] ③ During the overall movement of the net surface, external force is applied to the package 3 that has been adhered to both sides of the net surface to shape it, gradually bending it from a foil shape inward to a semi-closed structure with the inner center line of the package 3 as the axis of symmetry and the warp 1 as a whole and the intersection of the warp 1 and the weft 2 as the contents.

[0042] ④ After the mesh surface and the wrapping material 3 are bent into a semi-closed structure, a step-by-step linear pressing process is applied to both sides of the mesh surface to gradually compress the wrapping material 3 distributed on both sides of the weft yarn 2, ultimately bonding them together and encapsulating the entire warp yarn 1 and the junction of warp yarn 1 and weft yarn 2 within the wrapping material 3. Negative pressure can be applied during the pressing process to ensure the wrapping material 3 is tightly adhered.

[0043] ⑤ Wrap and roll up the climbing net that has been wrapped and pasted on both sides to form a shape. Example 2

[0044] like Figure 2 As shown, this embodiment provides a climbing net specifically for vine crops. The climbing net comprises two warp threads 1 and two weft threads 2. The weft threads 2 intersect the two warp threads 1 at equidistant points in sequence from the top, outside, and bottom, forming the net surface. The two weft threads 2 intersect at the middle position. Sheet-like coverings 3 are provided along the sides of the warp threads 1, and the characteristics of the coverings 3 are the same as in Embodiment 1.

[0045] The production method is similar to that of Example 1, except that the unwinding and guiding operations of two warp threads 1 and two weft threads 2 are carried out simultaneously in the initial stage, and the subsequent processing steps of the package 3 are the same as those in Example 1. Example 3

[0046] like Figure 3 As shown, this embodiment provides a climbing net specifically for vine crops. Based on Embodiment 2, a third warp 1 is installed along the middle position of the two warp threads 1. This third warp 1 is parallel to the existing warp threads 1 and located between the two weft threads 2 at the intersection point. A wrapping material 3 of equal length is installed on both the front and back sides of the third warp 1. After compression, the two wrapping materials 3 are aligned and glued together, enclosing the intersection point and the two weft threads 2 within the width of the wrapping material 3. The wrapping materials 3 installed along the sides of the other two warp threads 1 are the same as in Embodiment 2.

[0047] Its production method is as follows:

[0048] ① At the beginning stage, the three warp threads 1 are simultaneously unwound and guided at equal intervals. Then, the weft threads 2 are wrapped and crossed around the plane formed by the three warp threads 1 to form a net surface, and the net surface is then rolled up.

[0049] ② During the winding process, the two sides of the mesh are respectively bonded to the inner side of the unwound and guided package 3. At the same time, two packages 3 with opposite inner sides and parallel to the mesh are set up and bonded to the two sides of the intersection of the third warp 1 and the warp 1 weft 2 respectively.

[0050] ③ The entire mesh surface moves synchronously with all the wrapped items 3, and gradually applies force to the wrapped items 3 to shape them. Among them, the wrapped items 3 on both sides of the third warp 1 need to be linearly pressed step by step, and the wrapped items 3 on both sides are gradually squeezed and finally attached together, so that the entire third warp 1 and the junction formed with the weft 2 are completely sealed in the wrapped items 3. The wrapped items 3 corresponding to the other two warp 1 are processed in the same way as in Example 2.

[0051] ④ During the packaging process of package 3, negative pressure can be used to ensure tight adhesion, and finally the climbing net is wrapped and rolled up. Example 4

[0052] like Figure 4 As shown, this embodiment provides a climbing net specifically for vine crops. The net divides the distance between the two outermost warp threads 1 into equal parts. At each division point, two identical warp threads 1 parallel to the warp threads are placed, intersecting with the weft threads 2. A wrapping material 3 of equal length is placed on the front and back of the two newly added warp threads 1. After compression, the two wrapping materials 3 are aligned and glued together, enclosing the portion of the warp thread 1 and the intersecting weft thread 2 within the width of the wrapping material 3. The arrangement of the wrapping materials 3 corresponding to the two outermost warp threads 1 is the same as in Embodiment 1 or Embodiment 2.

[0053] Its production method is as follows:

[0054] ① At the beginning stage, the four warp threads 1 are simultaneously unwound and guided at equal intervals.

[0055] ② After the latitude lines 2 intersect to form a net surface, the outermost two sides of the wrapping material 3 are treated in the same way as the two warp lines 1 climbing the net.

[0056] ③ For the two newly added warp threads 1 inside the mesh, each warp thread 1 corresponds to two inner opposite wrapping materials 3 that are parallel to the mesh surface. The wrapping materials 3 are gradually subjected to force to shape them and finally fit together, so that the corresponding warp thread 1 as a whole and the intersection with the weft thread 2 are completely encapsulated in the wrapping material 3.

[0057] ④ During the packaging process of package 3, negative pressure is applied to ensure tight adhesion, and finally the climbing net is wrapped and rolled up. Example 5

[0058] like Figure 5As shown, this embodiment provides a climbing net specifically for vine crops. Based on embodiment 4, the number of parallel warp threads 1 is further increased, for example, by adding three new parallel warp threads 1. The processing method is similar to embodiment 4, that is, each new warp thread 1 corresponds to two inner, opposite, and parallel wrapping materials 3. The wrapping materials 3 are processed accordingly to wrap the warp thread 1 and the junction. The production method is similar to embodiment 4, except that the number of unwinding and guiding warp threads 1 is increased at the beginning stage. The subsequent processing method of the wrapping materials 3 corresponding to different positions of the warp thread 1 remains unchanged. Similarly, negative pressure is applied during the wrapping material 3 sealing process, and finally, the net is wound and rolled into shape.
