Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire mesh joint technology, and in particular to a wire mesh joint structure. Background Technology
[0002] In actual production, the two ends of the wire mesh (hereinafter referred to as the first end and the second end of the wire mesh) need to be joined together to form a ring mesh. The existing method of connection is to overlap the first end and the second end of the wire mesh and then sew them together. This overlapping method results in uneven joint flatness due to the rough edges (causing burrs); it is prone to tearing and ripping; and the joint is prone to cracking at the needle holes (caused by the roller reversing direction). Utility Model Content
[0003] The first objective of this utility model is to provide a steel wire mesh joint structure with good flatness and reliable connection at the joint, which solves the problems of poor joint flatness and poor connection strength in the existing single-layer overlapping and sewing connection of steel wire mesh joints.
[0004] The second objective of this invention is to provide a wire mesh joint structure that is less prone to cracking at stress concentration points during bends, thus solving the problem that existing wire mesh joints are prone to cracking at the needle holes when passing through a drive roller.
[0005] The above technical problems are solved by the following technical solution: a wire mesh joint structure, comprising a first end and a second end of the wire mesh, characterized in that the connecting end of the first end of the wire mesh is folded to form a first end thickened portion, and the connecting end of the second end of the wire mesh is folded to form a second end thickened portion. A first end-head pin buckle is attached to the first end thickened portion, and a second end-head pin buckle is attached to the second end thickened portion. The first end-head pin buckle and the second end-head pin buckle are hinged together by a connecting pin to form the wire mesh joint. After folding, it is fixed by the buckles, making it less prone to tearing. The connection is reliable, compact, and convenient.
[0006] Preferably, the connecting end of the first end of the wire mesh is located on the lower surface of the thickened portion of the first end, and the connecting end of the second end of the wire mesh is located on the lower surface of the thickened portion of the second end. This improves the flatness of the upper surface and prevents the joint from warping and damaging the objects conveyed on the wire mesh. The drawback of this solution is that when the wire mesh is connected in a loop and used as a conveyor belt, the joint is prone to breakage when turning at the drive roller.
[0007] Preferably, the upper surface of the wire mesh joint is covered with an upper adhesive layer, and the lower surface is covered with a lower adhesive layer. The upper and lower adhesive layers are bonded together through the mesh openings at the first and second ends of the wire mesh. The edge of the upper adhesive layer at the first end extends beyond the thickened portion of the first end, and the edge at the second end extends beyond the thickened portion of the second end. Similarly, the edge of the lower adhesive layer at the first end extends beyond the thickened portion of the first end, and the edge at the second end extends beyond the thickened portion of the second end. This design prevents breakage at the connection points between the thickened portion and the buckle, as well as at the edges of the folds. These two areas are prone to breakage.
[0008] Preferably, the upper adhesive layer has serrated edges at both the first and second ends of the wire mesh, and the lower adhesive layer has serrated edges at both ends. This prevents stress concentration and cracking at the edges of the adhesive layers during use.
[0009] Preferably, both the upper and lower adhesive layers are made of polytetrafluoroethylene (PTFE). Of course, other PTFE materials can also be used.
[0010] Preferably, both the first and second end pin buckles are made of metal.
[0011] Preferably, both the first and second end pin buckles are made of stainless steel.
[0012] The present invention has the following advantages: it is flat, has a reliable connection, and is not prone to cracking. Attached Figure Description
