Document Type and Number:
WIPO Patent Application WO/2022/242096
Kind Code:
A1
Abstract:
A multifunctional linkage-type feeding assembly of a sewing machine. The multifunctional linkage-type feeding assembly comprises a feed dog assembly (1a), a lifting power source (10) and a rotary power source (20), wherein the lifting power source and the rotary power source act on the feed dog assembly to execute a cloth feeding action of a sewing machine, and the rotary power source is provided with a thread trimming mechanism (1b) and a presser foot lifting mechanism (1c); and during a rotation process, the rotary power source can drive the feed dog assembly, the thread trimming mechanism and the presser foot lifting mechanism to be linked and to act sequentially. The multifunctional linkage-type feeding assembly of the sewing machine achieves the simplification of the structure of a driving mechanism and the continuity between processes, thereby significantly optimizing the manufacturing costs and the service life of the sewing machine.
