WIPO Patent Application WO/2022/242094
Kind Code:
A1
Abstract:
A sewing machine, comprising a cloth feeding apparatus (10), a thread cutting apparatus (40) and a presser foot lifting apparatus (30). The cloth feeding apparatus has a cloth feeding driving source (11) and a tooth lifting driving source (12). The thread cutting apparatus and the presser foot lifting apparatus have a rotating driving source (20). The cloth feeding apparatus is further integrated with a multi-purpose adjusting assembly, and the cloth feeding driving source may drive the multi-purpose adjusting assembly to adjust the stitch length before the action of a needle, so as to ensure that the stitch length is adjusted in place before the action of the needle. Once the needle work is complete, the thread cutting apparatus and the presser foot lifting apparatus are driven by the rotating driving source to perform a thread cutting action and a presser foot lifting action in sequence. The sewing machine significantly optimizes the cooperating work capabilities of the apparatuses, and at the same time has the characteristics of a simplified structure and coherent action.
