Application of air ring of film blowing machine in plastic film blowing machine
1.Constant tension must be maintained throughout the winding process without manual adjustment;
2.The tension should not be too large when the empty coil is pneumatically operated to prevent the film from wrinkling.The tension shoule not be too small when the full coil is running to orevent the film from being too loose;
3.The system responds sensitively,and can quickly adjust according to the changes of the speed and tension of the previous stage during acceleration and deceleration to ensure constant tension;
4.It is required to quality the tension and set the tension according to the process requirements of different film production.
