AI Technical Summary
In the prior art, the wire feeding device for the weft wires during metal wire mesh weaving can easily scratch the end of the plastic roller, causing the weft wires to jam and affecting the smoothness of the wire feeding process.
The design incorporates a smooth metal ring, which, combined with a steering wheel and retaining ring, forms an annular groove that fits onto the end of the weft roller. This reduces contact between the weft yarn and the plastic end, prevents scratches by utilizing the smooth surface of the metal ring, and adjusts the weft yarn path via the steering wheel to reduce resistance.
It effectively prevents the weft yarn from getting stuck during the unwinding process, reduces the contact length between the metal ring and the weft yarn, lowers the unwinding resistance, and ensures smooth weft yarn delivery.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal wire mesh weaving technology, and in particular to a device for preventing the weft wires from jamming during release. Background Technology
[0002] Metal wire mesh is woven from metal wire, so the weft wires used to weave the metal wire mesh are also made of metal. However, the rollers that wind the weft wires are mostly made of plastic. If the wire feeding device of CN 213002395 U is used for wire feeding, the outer surface of the roller end is easily scratched and becomes rough when the wire feeding end of the weft wire passes through the blocking wire. This makes it easy for the weft wire to get caught during the wire feeding process, resulting in jamming. Utility Model Content
[0003] This invention proposes a device to prevent weft yarn from jamming during weft yarn release. When the weft yarn is released, it contacts the smooth surface on the outside of the metal ring. This smooth surface is not easily scratched, thus avoiding jamming.
[0004] The technical solution of this utility model is implemented as follows: a device for preventing weft yarn from jamming includes a metal ring, the outer side of which is an arc-shaped smooth surface, and a retaining ring is provided at one end of the inner side of the metal ring. An annular groove is formed between the retaining ring and the metal ring, with the opening end of the annular groove facing the other end of the metal ring. The metal ring is fitted onto the outer side of the end of the weft yarn roller, and the end of the weft yarn roller is engaged in the annular groove.
[0005] Furthermore, it also includes a bracket with a vertical positioning cylinder on it. A steering wheel is inserted into the upper end of the positioning cylinder. The outer side of the steering wheel is an arc-shaped and smooth metal surface. The outer diameter of the steering wheel is larger than the outer diameter of the metal ring. The steering wheel and the metal ring are arranged coaxially.
[0006] Furthermore, the bracket is also equipped with a connecting ring, which is fitted onto the outside of the positioning cylinder. The steering wheel and the connecting ring are arranged coaxially, and the outer diameter of the steering wheel is smaller than the inner diameter of the connecting ring.
[0007] Furthermore, the metal ring and the retaining ring are integrated into one structure.
[0008] Furthermore, the metal ring, retaining ring, and annular groove are arranged coaxially.
[0009] The beneficial effects of this utility model are: This invention uses an annular groove to fit a metal ring onto the outer side of the end of the weft yarn roller. The weft yarn contacts the smooth surface of the outer side of the metal ring, which is not easily scratched, thus avoiding jamming.
[0010] Based on the metal ring, this invention further incorporates a steering disc. By adjusting the weft yarn feeding path through the metal ring and steering disc, the weft yarn is prevented from contacting the plastic end of the roller during unwinding, while also reducing the contact length between the weft yarn and the metal ring, thus reducing unwinding resistance.

[0014] 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.
[0015] Example 1 like Figure 1-3 As shown, the device for preventing the weft yarn from getting stuck includes a metal ring 1. The outer side of the metal ring 1 is a smooth arc-shaped surface 2. A retaining ring 3 is provided at one end of the inner side of the metal ring 1. The inner side of the metal ring 1 and the retaining ring 3 are an integral structure. An annular groove 4 is formed between the retaining ring 3 and the metal ring 1. The metal ring 1, the retaining ring 3 and the annular groove 4 are arranged coaxially. The opening end of the annular groove 4 faces the other end of the metal ring 1.
[0016] The method of using the device is as follows: The end of the roller 5 with the weft yarn 6 wound on it is clamped in the annular groove 4, and the metal ring 1 is fitted on the outside of the end. When the weft yarn 6 is released, it passes through the outside of the metal ring 1. Because the metal ring 1 is made of metal and the outside is a smooth arc-shaped surface 2, it is not easy to be scratched by the weft yarn 6, thereby avoiding jamming.
[0017] Example 2 This embodiment is basically the same as the previous embodiment, except that: Figure 4 As shown, the device for preventing the weft yarn from getting stuck also includes a bracket 7, on which a vertical positioning cylinder 8 is fixed. A steering wheel 9 is inserted into the upper end of the positioning cylinder 8. The outer side of the steering wheel 9 is an arc-shaped and smooth metal surface 10. The outer diameter of the steering wheel 9 is larger than the outer diameter of the metal ring 1. The steering wheel 9 and the metal ring 1 are arranged coaxially.
[0018] A connecting ring 11 is also fixed on the bracket 7. A blocking wire is fixed on the inner side of the connecting ring 11 along the circumferential direction. The connecting ring 11 is fitted onto the outer side of the positioning cylinder 8. The steering wheel 9 and the connecting ring 11 are arranged coaxially. The outer diameter of the steering wheel 9 is smaller than the inner diameter of the connecting ring 11.
[0019] The upper end of the roller 5, which is wound with weft yarn 6, is fitted into the annular groove 4. The metal ring 1 is fitted onto the outer side of the upper end. Then, the roller 5 is fitted vertically onto the positioning cylinder 8. The metal ring 1 is located inside the connecting ring 11. The blocking wire abuts against the outer side of the metal ring 1. Then, the steering disc 9 is inserted into the upper end of the positioning cylinder 8. The feeding end of the weft yarn 6 passes through the outer side of the metal ring 1 and through the blocking wire, and then enters the feeding hole on the bracket 7 through the outer side of the steering disc 9.
[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
