Description

Cotton grabbing device for cotton yarn production Technical Field The invention relates to the technical field of cotton yarn production, in particular to a cotton grabbing device for cotton yarn production. Background In the cotton processing industry, a bale plucker is used as core equipment for a scutching process, and the main task of the bale plucker is to evenly grab raw cotton from a cotton bale and convey the raw cotton to a subsequent process for further treatment through air flow. The cotton grabbing efficiency and stability directly influence the productivity and the product quality of the whole production line. With the continuous improvement of the requirements of the textile industry on automatic and continuous production, the working performance and the maintenance convenience of the cotton grabbing equipment are increasingly emphasized. The prior cotton grabbing device has a plurality of technical problems which restrict the production efficiency in the actual operation. Firstly, during cotton conveying, part of fibrous materials are easy to leak and escape from a conveying system due to air flow fluctuation, poor sealing or gaps at the joints of pipelines. This not only results in waste of raw materials and increased production costs, but also the scattered cotton fibers may accumulate around the equipment or in the workshop environment, affecting the sanitation of the working environment, and even having a certain fire hazard. Secondly, the raw cotton contains cotton seed hulls, impurities, short velvet and other substances, and is extremely easy to cause hanging flower and accumulation at a pipeline elbow, a reducing position or the inner wall of a conveying channel in the air flow conveying process, so that blockage is gradually formed. The blockage of cotton outlet pipeline can directly lead to the interruption of grabbing cotton, and manual cleaning is needed to shut down, and traditional cleaning mode often needs to dismantle the pipeline, and complex operation is consuming time, seriously influences the continuity and the stability of production. The cotton grabbing shaft is used as a core execution component of the cotton grabbing assembly, is in direct contact with cotton in the working process and bears a certain mechanical load, is easy to wear or deform after long-term operation, and needs to be replaced periodically.
