Description

Technical Field

[0001] The utility model relates to a connecting structure of an insect-proof net package edge, in particular to an insect-proof net package edge connecting structure and a special pre-forming tool. Background Art

[0002] In agricultural production, the insect-proof net mainly plays the roles of preventing insects, preventing diseases, regulating temperature and shading strong light. Since the width of the insect-proof net is limited, multiple pieces of insect-proof nets need to be connected during use. At the same time, when installing the insect-proof net, it needs to be fixed on the shed frame through buckles. Currently, the common method is to place a metal wire at the edge of one side close to two pieces of insect-proof nets, then fold the edge and sew it through a sewing device and wrap the metal wire inside. During use, it is buckled on the metal wire and the outer folded edge of the metal wire through a buckle, and the folded edge and the metal wire at the connection of the two pieces of insect-proof nets are fixed on the shed frame through the buckle; after the insect-proof net is fixed, the folded edge is affected by the force of the buckle, and the mesh holes at the folded edge become larger after a period of time, thus failing to achieve the insect-proof effect; in addition, the insect-proof net has requirements for the mesh size, and the insect-proof net cannot be woven too densely, otherwise it will affect the air permeability. Therefore, the strength of the insect-proof net is limited, and local damage will also occur at the folded edge under long-term pulling. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an insect-proof net package edge connecting structure, which wraps a layer of package edge on the outer side of the folded edge of two connected pieces of insect-proof nets, and moves the metal wire from the inner side of the folded edge to between the folded edge and the package edge; the package edge adopts a mesh cloth with denser weaving and higher strength. After adopting the above package edge connecting structure, the strength at the connection of the two pieces of insect-proof nets is improved. At the same time, since the package edge is wrapped on the outer layer of the folded edge, even if the mesh holes of the package edge become larger under the action of the buckle, it does not affect the insect-proof effect of the insect-proof net inside the package edge, and at the same time, the strength of the folded edge is enhanced, avoiding the problem of local damage; in order to facilitate the realization of the above package edge connecting structure, the utility model adopts a special pre-forming tool for the folded edge and the package edge to realize the rapid sewing of the package edge connecting structure, with the characteristics of reasonable specific structure, reliable and stable connection, and more convenient sewing operation.

[0004] To achieve the above purpose, the following technical solutions are adopted:

[0005] An insect-proof net package edge connecting structure, comprising two pieces of insect-proof nets, characterized in that: the two pieces of insect-proof nets are aligned and stacked on one side and folded to one side, a layer of package edge is wrapped on the outer side of the folded edge, a metal wire is placed on the outer side of the bending part of the folded edge inside the package edge, the folded edge and the package edge are connected by a sewing method, and the metal wire is wrapped between the folded edge and the package edge.

[0006] A preforming special tool for the edge connection structure of an insect-proof net, characterized in that: the preforming special tool includes a hemming channel, the side of the hemming channel has an opening for the insect-proof net to pass through, a wrapping channel is arranged outside the hemming channel, and the heights of the channels of the hemming channel and the wrapping channel gradually decrease from the entrance to the exit. When reaching the exit, the exit ends of the hemming channel and the wrapping channel are in a flat structure; a wire guide is also arranged at the entrance of the wrapping channel.

[0007] A bottom plate is also arranged at the opening of the hemming channel.

[0008] A fixing plate is arranged outside the wrapping channel.

[0009] The wire guide is in a snake-like structure.

[0010] In the utility model, a layer of wrapping is wrapped outside the hem of one side of two insect-proof nets. The wrapping uses a net cloth with a denser weave and higher strength. The wire is wrapped by the wrapping outside the hem. When the wrapping is subjected to the buckle pulling force, even if the wrapping is damaged, it will not damage the insect-proof net of the wrapping, increasing the connection strength at the joint of the insect-proof net, and at the same time ensuring the long-term insect-proof effect of the insect-proof net; stitching is carried out through the preforming special tool, the stitching operation is more convenient, and the edge connection structure of the insect-proof net has better consistency.

[0019] As shown Figure 2-8 in the figure, an edge - folding connection structure of an insect - proof net includes two insect - proof nets 1. One side of the two insect - proof nets 1 is aligned and stacked, and is folded to form a folded edge 11. A layer of edge - wrapping 2 is wrapped outside the folded edge 11. A metal wire 3 is placed outside the bending part of the folded edge 11 on the inner side of the edge - wrapping 2. The folded edge 11 and the edge - wrapping 2 are connected by sewing, and the metal wire 3 is wrapped between the folded edge 11 and the edge - wrapping 2.

[0020] A special pre - forming tool for the edge - folding connection structure of an insect - proof net. The special pre - forming tool includes a folded - edge channel 5. The side of the folded - edge channel 5 has an opening 51 for the insect - proof net to pass through. A supporting plate 9 is also arranged at the opening of the folded - edge channel 5. An edge - wrapping channel 6 is arranged outside the folded - edge channel 5. The cross - sections of the folded - edge channel 5 and the edge - wrapping channel 6 are in an inverted U - shape. The edge - wrapping channel 6 surrounds the outside of the folded - edge channel 5. A fixing plate 8 is arranged outside the edge - wrapping channel. The heights of the folded - edge channel 6 and the edge - wrapping channel gradually decrease from the entrance to the exit. When reaching the exit, the exit ends of the folded - edge channel and the edge - wrapping channel are in a flat structure. A metal - wire guiding frame 7 is also arranged at the entrance of the edge - wrapping channel. The metal - wire guiding frame 7 is in a snake - like structure.

[0021] In the utility model, a layer of edge - wrapping is wrapped outside the folded edge on one side of the two insect - proof nets. The edge - wrapping uses a mesh cloth with denser weaving and higher strength. The metal wire is wrapped by the edge - wrapping outside the folded edge. When the edge - wrapping is subjected to the pulling force of the buckle, even if the edge - wrapping is damaged, it will not damage the insect - proof net of the edge - wrapping, increasing the connection strength at the joint of the insect - proof net and ensuring the long - term insect - proof effect of the insect - proof net.

[0022] During sewing, the special pre - forming tool is used for sewing. The special pre - forming tool is fixed on the table of the sewing equipment through the fixing plate 8. Then the edge - wrapping enters the edge - wrapping channel from the entrance of the special pre - forming tool and comes out from the exit. The metal wire passes through the snake - like metal - wire guiding frame 7 and the edge - wrapping channel and is wrapped by the edge - wrapping. Then the two insect - proof nets stacked on one side enter from the entrance of the folded - edge channel 5 and come out from the exit. At this time, the folded edges of one side of the two insect - proof nets are completed, and the folded edges are wrapped by the edge - wrapping. The metal wire passes through between the edge - wrapping and the folded edge. The pre - formed edge - folding connection structure enters the sewing equipment for sewing operation.

[0023] In addition, a supporting plate 9 is also arranged at the opening of the folded - edge channel 5 in the utility model. Since the area of the insect - proof net is large, adding the supporting plate 9 to support the part of the insect - proof net that has not entered the folded - edge channel is convenient for sewing operation. The utility model has more convenient sewing operation and makes the consistency of the sewn edge - folding connection structure of the insect - proof net better.
