Embodiment Construction

[0021] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0022] like Figure 1 to Figure 4 As shown, the driving structure in the sewing machine includes an adjustment motor 4, a feed tooth 13, a tangent drive arm 18, and a feed adjustment seat 16. The output shaft of the adjustment motor 4 is connected to the feed adjustment seat 16 and can drive the feed adjustment seat 16 to move. The feeding adjustment seat 16 is connected to the feeding tooth 13 and the thread cutting driving arm 18 respectively, wherein the movement of the regulating seat can be adjusted by adjusting the motor so as to drive the lifting height of the feeding tooth 13 and drive the thread cutting driving arm 18 to perform thread cutting.

[0023] Working principle of the present invention: by adjusting the ...

Abstract

The invention provides a driving structure in a sewing machine, and belongs to the technical field of machinery. The driving structure in the sewing machine comprises an adjusting motor, feeding teeth, a thread cutting driving arm and a feeding adjusting base, wherein an output shaft of the adjusting motor is in transmission connection with the feeding adjusting base and can drive the feeding adjusting base to move; the feeding adjusting base is in transmission connection with the feeding teeth and the thread cutting driving arm; and the adjusting base can be adjusted to move through the adjusting motor, so that the lifting height of the feeding teeth is driven, and the thread cutting driving arm can be driven to cut threads. The driving structure in the sewing machine provided by the invention has the advantages that the motor can control the thread cutting action and adjust the lifting height of the feeding teeth at the same time.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a driving structure in a sewing machine. Background technique [0002] At present, during the use of sewing machines, different types of sewing fabrics are required. These fabrics will have different thicknesses and smoothness. In order to make the fabrics have better smoothness in the sewing process, the existing sewing machine operation In the process, the angle of the tooth-lifting swing arm is often adjusted to control the height of the feeding teeth, thereby improving the smoothness of feeding. However, the adjustment of the swing arm needs to loosen the upper elastic screw, which makes this adjustment method very complicated and difficult to operate. At the same time, it needs to rely on experience to adjust during the adjustment process, which increases the uncertainty of the adjustment. The traditional tangent also realizes the control tangent action through a separate...
