Description

Technical Field

[0001] This utility model relates to the field of weaving tools technology, specifically a new type of metal wire heddle for nylon weaving. Background Technology

[0002] Gauze fabric is a traditional Chinese silk fabric, made using a weave technique where warp threads are twisted and weft threads are interlaced to form the yarn holes. It is mainly used for shoe uppers and clothing fabrics. Gauze fabric is generally woven using heddles, as disclosed in patents such as CN111074399A and CN221371421U, which disclose heddles used for weaving gauze fabric and reveal their basic structure and working principle.

[0003] Patent CN221371421U discloses a novel metal wire heddle for leno fabrics, in which a pair of base heddles are fixed with opposing heddle guide plates. The heddle guide plates have corresponding guide grooves for sliding through the left and right supports of the heddle. The heddle guide plates are made of metal and are connected to the base heddles by welding or bonding. Figure 1-2 It can be seen that its heddle guide plate is composed of an upper plate and a lower plate, and a guide groove is formed between the upper and lower plates. When working, the yarn is easily broken by the guide plate. In addition, the base heddle and the heddle guide plate are two separate parts connected by welding or bonding, which makes the structure and processing more complicated and has shortcomings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a new type of metal wire heddle for nylon weaving, which has a simpler structure, is easier to produce, and is less prone to yarn breakage during use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A novel type of metal wire heddle for nylon weaving includes a half heddle and a pair of base heddles. The pair of base heddles are symmetrically arranged on both sides of the half heddle. Each base heddle includes a bent portion in the middle, comprising an inner bend area in the upper half and an outer bend area in the lower half. The corresponding parts of the inner and outer bend areas are provided with transversely penetrating guide grooves, and the transverse bending distance of the inner bend area is greater than that of the outer bend area. The half heddle is movably inserted into the base heddles through the guide grooves from the middle to both sides. The base heddles guide and clamp the half heddle through the inner and outer bend areas on the front and back sides of the guide grooves.

[0007] Preferably, the ensemble further includes an upper ensemble ring at the top and a lower ensemble ring at the bottom.

[0008] Preferably, the base helium, the bent portion, the upper helium ring, and the lower helium ring are integral bent structures of metal monofilaments.

[0009] Preferably, the semi-healer is provided with a heald hole, and the semi-healer is a thin metal sheet structure.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The base heald of this utility model is a one-piece bent structure of metal monofilament. The bent part is first punched to form a guide groove, and then bent to form an inner bending area and an outer bending area. The overall structure is very simple, which facilitates production and processing. The base heald guides and clamps the half heald through the inner bending area and the outer bending area on the front and back of the guide groove. The half heald is inserted and connected through the guide groove. Compared with the upper and lower piece heald guide plates of the prior art, it is not easy to clamp the yarn, so it is less likely to break the yarn, which brings convenience to the efficient production of nylon fabrics.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-2As shown, this utility model provides a technical solution: a new type of metal wire heddle for nylon weaving, comprising a half heddle 2 and a pair of base heddles 1, the pair of base heddles 1 being symmetrically arranged on both sides of the half heddle 2;

[0022] like Figure 1-6 As shown, the base helium 1 includes a bent portion 101 in the middle, and the base helium 1 also includes an upper helium ring 103 at the upper end and a lower helium ring 104 at the lower end. The base helium 1, the bent portion 101, the upper helium ring 103 and the lower helium ring 104 are stainless steel monofilament integral bending structures.

[0023] like Figure 2-4 As shown, the bent portion 101 includes an inner bending area 1011 in the upper part and an outer bending area 1012 in the lower part. The corresponding parts of the inner bending area 1011 and the outer bending area 1012 are provided with transversely penetrating guide grooves 102, and the transverse bending distance of the inner bending area 1011 is greater than the transverse bending distance of the outer bending area 1012.

[0024] like Figure 2 , 7 As shown, the half-heddle 2 is provided with a heddle hole 201. The half-heddle 2 is a thin metal sheet structure. The half-heddle 2 is movably inserted into the base heddle 1 through the guide groove 102 from the middle to both sides. The base heddle 1 uses the inner bending area 1011 and the outer bending area 1012 on the front and back of the guide groove 102 to movably clamp and guide the half-heddle 2.

[0025] After the basic assembly 1 is formed by punching and bending, all parts of the assembly are polished, including but not limited to the two ends of the metal monofilament and the edge of the guide groove 102, to ensure that the overall surface is smooth and burr-free.
