Description

Technical Field

[0001] The utility model relates to the technical field of clothing production, in particular to a thread feeding device of a sewing machine used in clothing production. Background Art

[0002] The thread feeding device of a sewing machine is an auxiliary device for a sewing machine, which is mainly used to feed the thread ball into the movement of the sewing machine for sewing. When a sewing machine is required for sewing in the production of clothing, a thread feeding device is required to transport a large amount of sewing thread.

[0003] The existing patent is a Chinese utility model patent for a thread feeding mechanism of a sewing machine for clothing production, with the publication number CN220867691U. By setting up a thread feeding structure, the sewing thread spindle can be restricted between two rotating disks by using an electric push rod, and then the gear motor is used to drive the connecting rod to drive the moving semi-ring to fit the sewing thread spindle through two racks. The sewing thread spindle is fixed during the use of the sewing machine to prevent it from shaking as the sewing thread is drawn during use. After the sewing thread spindle is fixed, the device can rotate it to release the thread, thereby preventing the sewing thread from breaking or tying during the rapid thread drawing process. However, the inventor found that the tension of the sewing thread cannot be adjusted when feeding the thread. Therefore, we propose a thread feeding device for a sewing machine for clothing production. Utility Model Content
