Problems solved by technology

[0002] At present, the head of the fully automatic sewing machine is an integrated mechanism with the hook part. In order to connect the main shaft of the machine head and the transmission of the hook shaft, the power transmission of the head and the hook part will be avoided, which not only takes up a lot of space, but also has poor flexibility.

Abstract

The invention discloses an independently driven swinging shuttle mechanism, comprising a motor, a rotating shuttle cover, a needle plate, a rotating shuttle shaft, a driven swing gear, a rotating shuttle base, a driving swing gear, a thread trimming cylinder, a coupling, an eccentric wheel connecting rod, an eccentric wheel, a thread shearing shaft clamp block, a thread trimming shaft, a thread hooking position sensing board, parking position sensing board, a thread hook position sensor, and a parking position sensor; the motor is mounted on the rotating shuttle base, and the motor drives, bythe coupling, the eccentric wheel with the eccentric connecting rod to move; the eccentric connecting rod drives the driving swing gear to swing; the driving swing gear drives the driven swing gear with a rotating shuttle shaft to swing, thereby driving the rotary hook to perform a swinging motion. Through the above structural design, automatic thread trimming can be realized, the sewing quality and precision can be improved, independent drive can be achieved, and the application is simpler and faster.

Description

technical field [0001] The invention relates to the technical field of sewing machines, and is especially suitable for an independently driven shuttle mechanism. Background technique [0002] At present, the head of the fully automatic sewing machine is an integrated mechanism with the hook part. In order to connect the main shaft of the machine head and the transmission of the hook shaft, the power transmission of the head and the hook part will be avoided, which not only takes up a lot of space, but also has poor flexibility. . Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an independently driven shuttle mechanism. In order to reduce the size of the machine, improve the flexibility of the machine, and improve the sewing quality, a motor is used to drive the shuttle mechanism independently. Separate the shuttle part. [0004] The purpose of the present invention is ach...
