Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a polishing equipment for industrial sewing machine parts which is convenient to replace. Background Art

[0002] Industrial sewing machines are key equipment in the clothing, luggage and other industries, and the quality of their accessories directly affects the performance and service life of the sewing machines. Polishing, as an important process to improve the surface quality of industrial sewing machine accessories, plays a key role in reducing friction, improving wear resistance, and enhancing aesthetics. For example, the bobbin, one of the important accessories of a sewing machine, is mainly used to wind the bottom thread, and cooperates with the bobbin case, needle and other parts to complete the formation of stitches during the sewing process. Polishing can reduce friction, improve stitch quality, extend service life, improve sewing efficiency and prevent winding disorder.

[0003] The polishing wheel replacement process of traditional polishing equipment is relatively cumbersome. When the polishing wheel needs to be replaced according to different polishing processes or due to wear, the operator needs to use special tools and spend a lot of time and energy to remove and install the polishing wheel. This not only reduces production efficiency and increases equipment downtime, but may also cause unstable polishing effects due to inaccurate installation, affecting the quality of accessories.
