A testing platform of auto-control and detection for yarn tension
摘要
Abstract
In view of the difficulty and complexity in actual process of yarn tension testing, the composition and movement principle of let-off and take-up mechanism were analyzed, which was based on the origin of yarn tension.With the aid of digital prototype and 3D printing technology, a simplified model of the mechanism composited by let-off, shedding and take-up was designed.A closed-loop feedback control module of yarn tension was designed and developed with pressure sensor, single chip microcomputer and C language programming, and the PWM wave was used to drive and regulate the speed of let-off and take-up motor, to keep the yarn tension dynamically stable within the allowed scope.A testing platform for simulation, detection and control of yarn tension was established, and the feasibility of the transmission mechanism and control system was verified through data acquisition and real-time adjustment of yarn tension.This provides a support for technique improvement and innovation of yarn tension testing.关键词
