What Is The Role Of Tension in The Slitting Line?

Slitting wire cutting cuts metal coils into strips of various widths, and then harvests the strips into small rolls for the next process. What is the purpose of tension in this device?
The winding and unwinding process of the slitting line requires balanced tension control, and the tension is given by the tension control machine. The principle of tension control machine control is to calculate the winding diameter by detecting the linear speed of the winding. Load torque = F*D/2 (F is the set tension, D is the current winding diameter). Therefore, when setting the tension, due to the calculation Knowing the current winding diameter, the load torque can be calculated.
The slitting line tension control can output a standard analog signal of 0-10V, which corresponds to the rated torque of the asynchronous motor. Therefore, we use this analog signal to access the frequency converter and select the torque reference. In this way, the tension can remain constant throughout the dynamic winding process. In torque converter mode, speed is limited. In the tension control mode, whether it is a DC motor, an AC motor or a tool holder motor, the speed must be limited. Otherwise, when the torque generated by the motor can overcome the load torque and run, rotational acceleration will occur and the speed will continue to increase, which is the so-called speed car.
Slitting line tension control requires a certain tension output on the output shaft of the motor, which can be adjusted when winding and unwinding are running at 0Hz. The main purpose of this requirement is to prevent the reel from stopping while running and to ensure that the reel head does not loosen when restarted. In this control system, the initial tension setting on the tension control machine can be adjusted to meet the requirements.
Slitting lines are mainly used in transformers, motors, home appliances, automobiles, packaging and other industries. It is a device for cutting other metal strips in the transformer and motor industry.
