Main way of tension control
The tension control method is generally divided into two types: open loop control mode and closed loop control mode. The open loop control is to directly drive the winding mechanism with an electric motor having a similar winding characteristic n = kD (n is the rotational speed, k is a constant, and D is the diameter of the winding roller) to obtain an approximate constant tension operation. The open loop control has poor randomness and low control precision. The closed loop tension control has two kinds of direct tension control and indirect tension control. In the actual production process, the volume is adjusted, that is, the tension is fed back, compared with the given tension, and then the difference is applied to the regulator to adjust the controlled object so that the output tension meets the actual demand. It is called direct tension closed-loop control. This method can eliminate the steady-state error without considering various compensations. The indirect tension control uses the motor speed-torque characteristic curve to control the torque to control the torque, so as to achieve the purpose of controlling the tension. This method requires dynamic and static compensation. Sometimes, in order to obtain more precise control performance, a composite tension control method is adopted, that is, the required control amount is first determined according to an indirect control algorithm, and various compensations are considered to make the indirect control as accurate as possible, and then the direct tension control is used for fine adjustment.

Slitting machine operating procedures -

Third, through the film:

14. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.
15. If necessary, perform parent roll adjustment, brake tension adjustment, and flattening roller position check at low speed.

Reasons, countermeasures and effects of BOPP film slitting quality ---

 

six. Burr
Most of the reason for the burrs is that the cutting knife is too blunt, and replacing the cutter can solve the problem. Different types of films have different degrees of wear and tear on the cutters. The thicker the thickness, the greater the wear on the cutters, and the wear of the cutters due to the titanium dioxide and other materials. It is fast, so it is necessary to adjust the blade cutting position or replace the blade according to different cutting objects in time to avoid the appearance of raw products. Due to the high cost of cutting the raw edge product (retrocuting processing cost and edge material loss), it is much higher than the value of the scrapping blade. Therefore, preventive measures should be taken, and the replacement cycle of the blade should be budgeted. Adjust or replace the blade before the problem occurs. Blades reduce losses.
