AI Technical Summary
Technical Problem
Existing technologies make it difficult to adjust tension during the plastic film winding process, resulting in loose winding and uneven winding speed.
Method used
The system employs a combination of floating and fixed guide rollers, monitors tension changes using a tension sensor, and adjusts the contact between the tension regulating roller and the film by rotating a turntable to achieve slight release or tightening, ensuring stable tension.
Benefits of technology
It achieves stable tension during the plastic film winding process, ensuring tight and uniform winding, and avoiding the need to change the winding speed.

Abstract
The utility model discloses a plastic film winding tension adjusting device which comprises a winding frame, a first guide frame, a second guide frame, a tension sensor, a sensor support, a rotating disc and a controller, a first fixed guide roller and a floating guide roller are arranged on the first guide frame, the tension sensor is arranged on the sensor support, and a second fixed guide roller is arranged on the rotating disc. A transmission roller which extends outwards and is parallel to the first fixed guide roller is concentrically arranged in the tension sensor, a second fixed guide roller parallel to the first fixed guide roller is arranged in the second guide frame, and a first motor is arranged on the front side of the sensor support. The rotating disc is arranged at the output end of the first motor and located on one side of the path of the plastic film, tension adjusting rollers extending to the upper portion and the lower portion of the path of the plastic film are symmetrically arranged on the rotating disc, and when the tension changes slightly, contact between the two tension adjusting rollers and the plastic film is changed through rotation of the rotating disc; and the plastic film is slightly released or tightened to stabilize the tension.
