Title:
SWITCHING CIRCUIT FOR CONTROLLING CLUTCH AND BRAKE OF LOOM, AND WORKING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/184752
Kind Code:
A1
Abstract:
A switching circuit for controlling a clutch and brake of a loom, and a working method thereof. The switching circuit comprises a power source circuit, a high-voltage control circuit, a brake and clutch control circuit and a single-chip microcomputer, wherein the power source circuit comprises a transformer, a rectifier circuit, a filter circuit and a voltage stabilization circuit; an output end of the single-chip microcomputer outputs KZGY, KZXC, KZZDQ and KZLHQ signals; the high-voltage control circuit provides a 100 V direct-current high voltage for the brake and clutch control circuit; and the brake and clutch control circuit comprises a demagnetization loop, a brake control loop and a clutch control loop. The working method comprises the following steps: a power source circuit working, a high-voltage control circuit working, realizing a demagnetization function, realizing a clutch function, and realizing a brake function. According to the switching circuit and the working method thereof, the effects of a high starting speed and sensitive inching of a loom can be achieved, and the weaving quality and the weaving efficiency can be improved.
