Title:
CLOTH-PUNCTURING TAKE-UP MODULE FOR SEWING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/206004
Kind Code:
A1
Abstract:
A cloth-puncturing take-up module for a sewing machine comprises a cloth-puncturing take-up shell, the cloth-puncturing take-up shell being provided with a needle and a cloth-puncturing take-up drive source for driving the needle to make a longitudinally reciprocating movement, a take-up lever being arranged in the cloth-puncturing take-up shell, and the cloth-puncturing take-up drive source driving the take-up lever to swing up and down. The present cloth-puncturing take-up module for a sewing machine combines the components for implementing cloth-puncturing and take-up functions to form a modular structure driven by the cloth-puncturing take-up drive source, arranged jointly in the cloth-puncturing take-up shell such that the movement sequence of the cloth-puncturing and take-up function components can be adjusted independently, shortening the entire transmission chain of the sewing machine, increasing the convenience of control and scheduling of the sewing machine, and facilitating maintenance of the sewing machine.
