Description

Technical Field

[0001] The utility model relates to the technical field of rapier heads, in particular to a rapier head for a rapier loom. Background Art

[0002] Rapier loom is a kind of mechanical equipment widely used in textile industry. Its main function is to introduce weft yarn into the shed of warp yarn through the movement of rapier head to complete the interweaving of warp and weft yarn. However, there are some problems in the design and use of existing rapier heads, such as complex structure, fast wear, low weft insertion efficiency, etc., which affect the overall performance of rapier loom and the quality of fabric. However, since the rapier head needs to produce friction with warp yarn, guide hook, guide plate and guide rail when advancing and retracting the rapier, it is inevitable to wear after long-term operation. Wear is most likely to occur on the head and two wings of the rapier head. When the two wings of the rapier head are severely worn and form a knife-edge shape, it is easy to cause the warp yarn to break, and even make the rapier head jump out of the shed without the control of the guide hook, resulting in a large number of broken ends. In the use of existing rapier heads, it will be worn in the process of high-speed weft yarn introduction. After wear, the disassembly and replacement of the rapier head is relatively complicated, and the operation is cumbersome, which reduces the working efficiency of the rapier loom. In addition, the size of the rapier head cannot be increased or decreased, which limits the scope of use of the rapier head. Utility Model Content
