AI Technical Summary
In the existing technology, during the production of polyolefin diaphragms, the inability to promptly report linear speed differences leads to inaccurate roller speed adjustment, affecting conveying stability, causing membrane slippage, deformation, and damage, and reducing product quality.
A device comprising an electric roller, a blade rotary cylinder, an angular displacement sensor, and a conveying limit mechanism was designed. The torque value is set by the blade rotary cylinder, and the rotation speed is adjusted by the feedback from the angular displacement sensor to achieve precise control of the linear speed of the electric roller. The conveying path is adjusted by the limit ring to ensure stable film conveying.
It achieves precise control of membrane tension, ensuring the tension stability of the polyolefin membrane during the conveying process, improving production efficiency and the dynamic adjustment capability of the equipment, avoiding membrane offset and damage, and meeting the requirements of high-precision production.
