Description

Technical Field

[0001] The utility model relates to the technical field of drawing frames, in particular to a cotton spinning drawing frame with a self-cleaning function. Background Art

[0002] The drawing frame is a mechanical equipment in the field of textile science and technology, mainly used in cotton mills. Its function is to improve the internal structure of the sliver, improve the uniformity of the long segments of the sliver, and reduce the weight unevenness. Under the action of the drawing frame, the fibers in the sliver will be straightened and parallel, reduce the hooks, and make the fineness meet the requirements. At the same time, it can also make raw materials of different types or qualities mix evenly to achieve the specified mixing ratio;

The cotton spinning stranding and drawing machine can not only remove static electricity on the cotton strips, but also dry and remove dust from the cotton strips;

[0004] When the above-mentioned prior art is in use, it mainly utilizes a suction fan to absorb the lint on the noodles for cleaning. The method is single and relies on the suction power of the suction fan. When some lint or short fibers are mixed between multiple groups of cotton strips, incomplete adsorption may occur, thereby affecting the cleaning effect. In addition, since the surface of the cotton strips generally contains cotton wax, the cotton wax may stick to the conveying roller during the cotton strip drawing and conveying process. If it is not cleaned in time, a wax layer will be formed on the surface of the conveying roller, which will affect the yarn guiding effect and performance of the conveying roller, thereby affecting the overall drawing efficiency. Therefore, corresponding improvements are needed. Utility Model Content
