What is the tension detection system of the high-speed slitter? Let's understand it together.
        1. Unwinding tension detection system of slitter
        The tension sensor detects it is a direct detection of tension, which is closely combined with the machine and has a detection method of moving parts. Usually two sensors are used in pairs, and they are installed on the end shafts on both sides of the detection guide roller. By detecting the applied load on both sides of the guide roller, the material belt causes displacement or deformation of the tension sensor sensitive element, thereby detecting the actual tension value, and converting this tension data into a tension signal and feeding it back to the tension controller.
        2. Attenuation and tension compensation of tension of winding and unwinding of slitter
        It is generally believed that maintaining the constant tension of the aluminum foil during the unwinding and unwinding of the aluminum foil is beneficial to the performance of the finished aluminum foil, but this is not the case. The best way is to increase the tension of the aluminum foil according to a certain rule as the diameter or weight of the roll increases, and the smaller the diameter and weight, the smaller the tension value. Because there are automatic tension control and manual tension control in the slitting operation. Manual tension control requires the operator to continuously adjust according to the diameter and weight of the masterbatch.
        The automatic tension control system pre-sets the tension attenuation value, and the equipment is attenuated according to the change of the material roll during the operation. When setting the automatic tension operation, you should set the initial tension first, and then set the tension attenuation value. Taking the attenuation value of the slit aluminum foil unwinding as an example, the setting principle is: the aluminum foil tension attenuation value (%) is equal to the tension at the end of the winding of the aluminum foil minus the initial tension and then divided by the initial tension, and the quotient is multiplied by 100%. When setting the automatic tension value, it should not be too large, otherwise the surface hardness of the aluminum foil winding is large, and the edge curling phenomenon is easy to occur, but the tension should not be too small, too small, it is easy to cause the rewinding body to be too loose, and the winding is not neat. Therefore, the quality of the rewinding and unwinding during the aluminum foil slitting operation is mainly affected by the change of the aluminum foil tension. It can be seen that the mastery of the rewinding and unwinding control system is the key to affecting the quality.

        After reading the above, I believe everyone already knows the tension detection system of the high-speed slitting machine.
