Abstract

The transmission structure of a sewing machine provided by the present invention includes: a rotary hook mechanism for being installed under the needle plate; the rotary hook mechanism includes a third rotary hook gear, a rotary hook shaft, a gear cover and a rotary hook seat; The hook shaft penetrates into the third rotary hook gear and is fixedly connected with it, and the top of the rotary hook shaft is also driven to connect the rotary hook; the middle part of the gear cover is provided with an installation cavity, and the side wall of the gear cover is provided with an opening; The third rotary hook gear and the rotary hook shaft are installed in the installation cavity; the gear cover has an outer wall that fits with the inner wall of the rotary hook seat. The invention improves the structure of the gear cover, reduces the structure of the gear cover, and further reduces the size of the hook seat; reduces the size of the machine head, which can process specific products with smaller sizes; and does not need to replace the entire machine during maintenance. seat, only need to disassemble the first rotary hook mechanism separately, and its replacement and maintenance are more convenient.

Description

technical field [0001] The invention relates to the field of sewing machine devices, in particular to a sewing machine transmission structure. Background technique [0002] At present, in the transmission structure of the existing sewing machine, various gears mesh with each other for transmission, and the overall structure size is large. [0003] For example, the patent application number CN200720146583.4 discloses "Multi-head Embroidery Sewing Machine". independent motors; a motor common to a plurality of shuttles for driving the shuttles provided under the respective sewing machine heads; and the shuttles transmitting the rotation of the common motor to the respective sewing machine heads the transfer mechanism. The size of the machine head is large, so it is not suitable for the processing of specific products with small size such as children's shoes. SUMMARY OF THE INVENTION [0004] (1) Technical problems to be solved [0005] The purpose of the present invention...
