Abstract (en)
[origin: EP4029978A1] The invention relates to a rotor spinning device self-cleaning structure and a textile machinery as well as to a self-cleaning operation method, wherein the rotor spinning device self-cleaning structure comprises a spinning device that includes a cup insert for conveying cotton fibers, and a rotor. The rotor includes a condensing groove for forming a yarn, and includes a cleaning rod that can extend into and clean the condensing groove of the rotor when the rotor is in an operating state, and a driving device for driving the cleaning rod to operate. In addition, the rotor self-cleaning method comprises a rotor spinning device self-cleaning structure as described above, when the rotor is to be cleaned, the driving device drives the cleaning rod to move from an initial operating position to a cleaning operating position in which the cleaning rod is in contact with the condensing groove of the rotor in the rotating operating state. The invention can realize the cleaning of the rotor without stopping the machine and has a good cleaning effect, and at the same time can ensure the production efficiency of the textile machinery with the self-cleaning structure and improve the production benefit.
