Document Type and Number:
WIPO Patent Application WO/2021/120641
Kind Code:
A1
Abstract:
A sewing-starting and thread-cutting mechanism, comprising a thread-cutting fixed blade (100) that is fixedly provided, the edge (101) of the fixed blade being provided at an end of the thread-cutting fixed blade close to a needle (20) of a sewing machine; a thread-cutting movable blade (200), which is provided below the thread-cutting fixed blade; a thread-hooking groove (210) is provided on the top surface of the thread-cutting movable blade; the edge (201) of the movable blade is provided at an end of the thread-cutting movable blade close to the needle of the sewing machine; a driving part (300), which is connected to the thread-cutting movable blade. The driving part drives the thread-cutting movable blade to move along the length direction of the sewing machine between a thread-cutting position and a thread-hooking position; when the thread-cutting movable blade moves to the thread-cutting position, the edge of the fixed blade contacts the edge of the movable blade; and when the thread-cutting movable blade moves to the thread-hooking position, a thread-hooking hole of the thread-hooking groove moves below the needle of the sewing machine. Further comprised is a sewing-starting and thread-cutting method. The described mechanism can prevent bird nesting when starting sewing, reduce the process of trimming the ends of thread, and effectively reduce the probability of loose thread when starting sewing.
