A sewing machine control circuit with electronic mopping function

Abstract

The invention provides a sewing machine control circuit with an electronic cloth dragging function. The sewing machine control circuit with the electronic cloth dragging function mainly solves the technical problems that in the achieving process of an existing independent electronic cloth dragging function, cost is high, synchronization is unsatisfactory, occupied space is large and complete machine configuration is messy. According to the technical scheme, the sewing machine control circuit with the electronic cloth dragging function comprises a power supply, a rectifying and filtering circuit, a single-chip microcomputer U1, a single-chip microcomputer U2, a cloth dragging stepping motor, a handpiece servo motor, a foot switch and an operation panel. The power supply is connected to the rectifying and filtering circuit, the output end of the rectifying and filtering circuit is respectively connected with the single-chip microcomputer U1, the single-chip microcomputer U2, the cloth dragging stepping motor, the handpiece servo motor and the foot switch, the output end of the single-chip microcomputer U2 is connected with the cloth dragging stepping motor, a press-down electromagnet and a solenoid valve through a drive circuit, the output end of the single-chip microcomputer U1 is connected with the handpiece servo motor through a drive circuit, the signals of a coder of the handpiece servo motor are sent into the single-chip microcomputer U1 and the single-chip microcomputer U2 at the same time, the foot switch is respectively connected to the input end of the single-chip microcomputer U1 and the input end of the single-chip microcomputer U2, and the communication port of the single-chip microcomputer U1 and the communication port of the single-chip microcomputer U2 are in butt joint with the communication port of an MCU on the operation panel. The sewing machine control circuit with the electronic cloth dragging function is mainly applied to various computer sewing machine devices.

Description

Technical field [0001] The invention relates to a sewing machine control circuit, in particular to a sewing machine control circuit with electronic mopping function, which is mainly suitable for various industrial sewing machines (including three-automatic and partial automatic computerized lockstitch sewing machines, computerized overlock sewing machines, and computerized interlock sewing machines Wait for the sewing machine) to drag away the accumulated fabric that has been sewn in time to ensure that the sewing stitches are straight and beautiful. Background technique [0002] With the development of society, people’s requirements for the quality of life are getting higher and higher, and the requirements for the processing quality of clothing are also getting higher and higher. Especially for branded clothing, the requirements for sewing stitches are also higher. Due to different fabrics, different The styles and craftsmanship of many sewing machines will have wrinkles, uneve...
