The replacement and loading/unloading of the spinning cup joint is a key step in the maintenance of the rotary spinning machine, which requires strict adherence to operating standards and attention to details such as cleaning, lubrication, and installation. Standardized operation can not only improve equipment operating efficiency, but also reduce production costs. Operators should receive regular training, familiarize themselves with equipment structure and maintenance requirements, and ensure accurate operation at every step.
Regular cleaning
Clean the fiber accumulation on the inner wall of the spinning cup every 800-1000 hours of operation (using a cleaning brush or compressed air) to avoid fiber entanglement and overheating of the bearing.
Lubrication and maintenance
Supplement bearing grease every 2000 hours, with an appropriate amount to cover 1/3 of the bearing balls each time. Excessive amount can cause fiber adsorption.
Life management
The service life of the spinning cup joint is usually 3000-5000 hours, and it should be replaced in a timely manner according to the type of yarn (such as coarse yarn, which wears out faster). If the wear on the inner wall of the spinning cup is found to be greater than 0.1mm, it should be replaced immediately to avoid affecting the quality of the yarn.
