Abstract

The invention provides a sewing drive structure and a sewing machine provided with same. The sewing drive structure comprises a drive motor, a trimming mechanism, a presser foot lifting mechanism anda thread slacking mechanism, wherein the drive motor is separately connected with the trimming mechanism, the presser foot lifting mechanism and the thread slacking mechanism so as to drive the trimming mechanism, the presser foot lifting mechanism and the thread slacking mechanism to operate separately. Therefore, a movable cutter, a yarn trapper and a presser foot can be driven at the same timeby means of the one motor. The problem that in the prior art, the sewing machine adopts two independent devices to drive the movable cutter, the yarn trapper and the presser foot respectively, so thatthe overall structure of the sewing machine is complicated is solved.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a sewing drive structure and a sewing machine with the same. Background technique [0002] Existing sewing machines need two independent devices to drive the movable knife, thread clamp and presser foot respectively to perform actions such as thread trimming, thread loosening and presser foot lifting after the sewing is finished. [0003] However, the methods of thread trimming, thread loosening and presser foot lifting of the existing sewing machines can lead to complex overall structures, large volumes and unstable operation of the sewing machines. Contents of the invention [0004] The main purpose of the present invention is to provide a sewing drive structure and a sewing machine with it, so as to solve the problem that the sewing machine in the prior art uses two independent devices to drive the movable knife, the thread gripper and the presser foot respectively, which will...
