AI Technical Summary
The existing film winding equipment cannot adjust the tension of the film, resulting in poor winding effect.
An adjustable film winding device is designed, using a support mechanism and a rotating mechanism to cooperate with a pressure sensor to achieve the tensioning adjustment of the film by driving the motor and pulley, ensuring that the film reaches appropriate tension during the winding process.
By detecting the tension of the film and automatically adjusting the tension force, the film rolling effect is significantly improved, making the film rolling more compact and effective.
