Open-end spinning is a novel spinning technology which utilizes air flow to condense, twist and output fibers into yarn in a spinning cup which rotates at a high speed. The device does not need a spindle and mainly depends on a plurality of components such as a carding roller, a spinning cup, a false twisting device and the like. The spinning cup is a small metal cup and is shaped like a hollow thin-wall truncated cone. The maximum inner diameter of the inclined plane in the cup forms a condensation groove. The fibers reaching the inclined surface of the cup wall are arranged in parallel along the inclined surface of the inner wall and slide to the coagulation tank under the action of centrifugal force generated by high surface speed of the cup wall, and are superposed into an annular coagulation strand. The rotor rotates at high speed with the condensed fiber strand and the radial yarn arm connected with the condensed fiber strand, thereby realizing twisting and spinning.
In the spinning cup of the self-exhaust type rotor spinning commonly used in the spinning factory at present, the airflow flows from front to back (from the cup opening to the cup bottom), but because the diameter of the spinning cup cotton condensing groove is larger than the circumferential diameter of the distribution of the exhaust holes, impurities and dust are easy to precipitate and accumulate in the spinning cup cotton condensing groove, and the periodic fluctuation of the yarn evenness level is caused. The yarn broken ends can be caused by dust and impurities accumulated in the spinning cup cotton condensing groove, the yarn quality is influenced, the broken ends of the yarn are increased, and the finished rate of cotton yarns is reduced. Therefore, the cotton condensing groove of the spinning cup needs to be cleaned frequently, but the spinning cup is usually of an integral structure, and the opening at the top is smaller than the diameter of the cotton condensing groove at the bottom, so that accumulated dust needs to be removed during cleaning, and the cleaning is very inconvenient; and the spinning cup is integrally installed on the spinning machine and is usually horizontally placed, the whole spinning cup needs to be completely dismounted for cleaning ash, time is greatly consumed, abrasion can be increased for a long time, and therefore convenience for cleaning ash is urgently needed.
