Abstract

The invention provides a thread cutting method and system for an industrial sewing machine. The system comprises a charging-discharging component, a fusing component and a control module. The charging-discharging component is used for storing and discharging electric energy; the fusing component releases electric energy through the charging-discharging component to heat for fusing sewing thread ofthe industrial sewing machine; the control module is used for controlling the fusing component to fuse the sewing thread when the fusing component reaches a preset temperature, the control module comprises a control unit, a temperature detection unit, a driving unit, an electricity quantity detecting unit and a charging unit, and the charging unit acquires residual energy generated in braking ofa motor driver of the sewing machine and charges the charging-discharging component through the residual energy. By thread cutting through fusing, the problem of excessively long thread yarns is avoided, the problem of nests is reduced, and the defect rate in thread cutting is decreased. By making full use of energy generated by a motor of the sewing machine, brake resistor consumption is reduced,factory power consumption is reduced, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to the field of intelligent control of sewing machines, in particular to a thread trimming method and system for industrial sewing machines. [0002] Copyright statement [0003] The disclosure of this patent document contains material that is protected by copyright. This copyright belongs to the copyright owner. The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it exists in the official records and files of the Patent and Trademark Office. Background technique [0004] Industrial sewing machines, including lockstitch, overlock, interlock, and special machines, all need to use the thread trimming function. First: Most of the sewing machine thread trimming systems currently on the market still use solenoid valves or electromagnets to drive mechanical systems for thread trimming. This method of thread cutt...
