Description

Technical Field

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

[0002] Cotton yarn is the yarn made from cotton fiber through spinning process, and it is called cotton thread after plying. According to different spinning processes, it can be divided into carded yarn and combed yarn. In order to make the fibers in the cotton yarn straight and parallel, reduce hooks, and make the fineness meet the requirements, the cotton yarn needs to be stretched during the production process. In addition, before the cotton yarn is stretched, the broken fibers need to be combed out with a needle comb structure, but the combed fibers will be entangled on the comb needles. Too many fibers entangled on the comb needles will affect its working efficiency;

[0003] After searching, the prior art has an authorization announcement number of: CN214830934U, which discloses a stretching device for cotton yarn production, including a first outer shell, a stretching mechanism, a pressing mechanism, a needle combing mechanism, a cleaning structure and a dust collecting mechanism. The bottom outer wall of the first outer shell is fixedly connected to the second outer shell, and a cleaning structure is arranged in the second outer shell. The front outer wall of the first outer shell is fixedly connected to rotating motor 1, rotating motor 2 and rotating motor 3. The first outer shell is provided with a stretching mechanism, a pressing mechanism and a needle combing mechanism, and the inner wall of the first outer shell is rotatably connected to rotating rod 4. The present application can clamp the cotton yarn by means of a pressing block strip, and rotating motor 3 drives the fixed plate to rotate, and the rubber strip increases the friction between the cotton yarn and the cotton thread, so as to conveniently and effectively stretch the cotton thread. The present application cleans off the fibers wrapped around the combing needles by means of a cleaning hook, so as to avoid too many fibers wrapped around the combing needles affecting the working efficiency of the combing needles.

[0004] The above patent still has some problems when in use. After the cleaning hook cleans off the fibers wrapped around the combing needle, an exhaust fan and a drainage machine are used to suck in the fibers and cotton wool. However, the cleaned fibers may be wrapped around the cleaning hook. Simply using an exhaust fan cannot suck in the fibers wrapped around the surface of the hook. The fibers on the surface of the cleaning hook may gather more and more, making it impossible to continue cleaning the combing needle, and further making it impossible to continue cleaning the broken fibers on the surface of the cotton yarn. Therefore, we need to propose a stretching device for cotton yarn production. Utility Model Content
