Description

Technical Field

[0001] The utility model relates to the technical field of cotton yarn processing, in particular to a cutting device for cotton yarn processing and production. Background Art

[0002] Cotton yarn is made from cotton fiber through spinning technology. After plying, it is called cotton thread. According to different spinning processes, it can be divided into carded yarn and combed yarn. Carded yarn: yarn spun from cotton fiber through ordinary spinning system, combed yarn: yarn spun from cotton fiber through combed spinning system. Combed yarn is made of high-quality raw materials. The fibers in the yarn are straight and parallel, with few knots, good gloss, uniform yarn and high strength. This kind of cotton yarn is mostly used for weaving high-end fabrics.

[0003] During the cotton yarn processing, if the cotton yarn has been wound around the outside of the winding drum for a sufficient number of times, the cotton yarn needs to be cut in time and continue to be wound around the outside of the next winding drum. However, the existing cutting method is mostly manual cutting with scissors. The cutting process requires workers to stare for a long time to prevent too many winding circles. Staring for a long time will make the eyes dry and unbearable, which is not conducive to the health of the workers. Therefore, a cutting device for cotton yarn processing and production is proposed to solve the above problem. Utility Model Content
