The tension fluctuation and packaging quality control of nonwoven winding

In order to improve the package quality of nonwoven and reduce the defects in the nonwoven production process, the tension fluctuation in the winding process is studied. A winding device is built to package nonwoven, and the measured data of tension fluctuation is obtained. The tension fluctuation characteristic of the measured data is analyzed, and different tension fluctuation simulation curves have been set. Under different simulation curves, the corresponding package stress distribution is calculated, and the influence of tension fluctuation on package quality is analyzed. Accordingly, a fuzzy proportional integral differential (PID) control strategy is proposed to optimize the winding device to improve nonwoven product quality. Matlab establishes the PID and fuzzy PID simulation models, proving that fuzzy PID can significantly improve the system control performance.
