AI Technical Summary
During the tension adjustment process of existing fabric rolling machines, the accumulation of foreign objects on the surface of the tension roller leads to deviations in detection accuracy, affecting the uniformity of the fabric and production stability. This can easily result in problems such as slackness or tightness, leading to wrinkles and breakage.
The system employs a scraper and suction tube working together to automatically remove lint and impurities from the surface of the tension roller. Combined with a tension sensor and telescopic cylinder, it forms a closed-loop adjustment system that adjusts the position of the tension roller in real time to maintain constant tension, and is precisely controlled by a PLC system.
It effectively maintains the accuracy of tension detection, improves the uniformity of fabric winding and the continuity of the production process, reduces the occurrence of wrinkles and breaks, and improves the quality of fabric winding and production stability.
