Abstract

The embodiment of the invention discloses a sewing machine. A mechanical structure part comprises a thread leading mechanism, a thread picking mechanism, a thread hooking mechanism and a cloth feeding mechanism. The thread leading mechanism, the thread picking mechanism, the thread hooking mechanism and the cloth feeding mechanism share an upper shaft connected with an upper wheel, and the upper wheel is connected with a motor through a transmission mechanism. An electrical control part comprises a microcontroller, an intelligent power module and a motor, wherein the microcontroller, the intelligent power module and the motor are sequentially connected, the microcontroller is connected with a plurality of sensing / inputting devices to receive corresponding signals / input parameters or commands, and PWM signals are generated and output to be converted to motor driving signals through the intelligent power module, so that the motor is driven. The mechanical structure and the electrical control part are improved, and product performance can be comprehensively improved.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a sewing machine. Background technique [0002] The sewing machine is mainly composed of four major mechanisms such as a lead thread mechanism, a thread take-up mechanism, a thread hook mechanism, and a cloth feeding mechanism, and another independent bobbin winding mechanism. The regular movement of the parts can make the upper thread and the lower thread twist out of the lock ring like twisting a rope, thus forming a double-thread interlocking stitch. Ordinary sewing machines have certain defects. On the one hand, the mechanical structure is relatively complicated and the layout is not compact enough; on the other hand, the control of the motor is not convenient enough, and the dynamic performance is not ideal enough. In view of the shortcomings of existing sewing machines, it is necessary to improve this. Contents of the invention [0003] In view of the defects existing in the prior ar...
