Description

Technical Field

[0001] The utility model relates to the technical field of spinning processing, in particular to a thick section yarn defect remover for an air-spinning machine. Background Art

[0002] Yarn defects are major defects on the yarn. They are caused by improper spinning process design, poor equipment condition, and illegal operation of the spinning machine. There are two types: sudden and random. Sudden yarn defects appear in large quantities within a period of time, resulting in a large number of defective products. They are mainly produced in the front process close to the fine yarn. Random yarn defects appear sporadically and can be randomly generated in each process. Cotton, wool, linen, and silk yarn defects have different names due to industry habits, but the content and expression are similar. With the development of modern technology, a yarn defect remover will be installed on the top of the spinning machine to remove thick yarn defects, so as to improve the quality of the spun yarn.

[0003] In view of this, Chinese patent number CN2498170Y proposes a thick section yarn defect remover for air-spinning machines. There is a cutting edge between the two yarn cleaning scrapers, and the gap between the cutting edges is adjusted according to the thickness of the yarn count. The yarn count with large thick section defects will be automatically cut off and re-knotted by the thick section yarn defect remover, without the need for two rewinds, thus ensuring the quality of the yarn output. However, for the remover in the above technical solution, the distance between the scrapers needs to be manually adjusted for yarns of different thicknesses during use, but the manual adjustment of the scraper spacing error is large. If the spacing is too large, the yarn defect treatment will not be thorough. If the spacing is adjusted too small, the yarn is easily cut off, causing the thick section yarn limit separation to be interrupted, requiring a second yarn transfer, which reduces the yarn production efficiency.
