Title:
WEB GUIDING SYSTEM BASED ON DIRECT-CURRENT SERVO DRIVING
Document Type and Number:
WIPO Patent Application WO/2024/040849
Kind Code:
A1
Abstract:
A web guiding system based on direct-current servo driving, comprising a deviation measurement module (1), a servo guiding control system (2) and a guiding execution mechanism (3). The servo guiding control system comprises a guiding control module (21), a servo driving module (22), a direct-current servo motor (23), a rotary encoder (24) and a current measurement circuit (25). The deviation measurement module is used for measuring a position deviation signal of a web on a web output end of a target conveyor roller and sending the position deviation signal to the servo guiding control system. The servo driving module is used for, according to a PWM driving control signal output by the guiding control module, controlling the rotating direction, rotating speed and torque of the direct-current servo motor, so as to drive, by means of the direct-current servo motor, the guiding execution mechanism to carry out guiding control on the web. The present invention ensures that the direct-current servo motor has stabler output torque and does not jitter when running at a low speed and the motor achieves faster response when running at a high speed, and can effectively increase the guiding precision of the system, thereby effectively satisfying the requirement of the guiding use for high precision.
