hisdevice is to provide automatic control for drawing roller and feeding roller overinvariable tension. Features on detecting and controlling: for instance, invariabletension is needed during the drawing and feeding process of paper or plastic firm.According to the continuous change of the diameter of the roller, this device linearlyincrease or decrease the excitation voltage of magnetic powder braker or magnetic powderclutch so as to change the brake moment or the clutch moment on the roller.
Instead of a touch sensor on the roller or sending firm, an approach sensor is installedby the rolling spindle to detect any change of the diameter of the roller. Once change ofthe diameter of the roller is detected, signals will be sent back to the device. Then thedevice will output a corresponding control voltage. This device has a setting on the rangeof the diameter. When the roller reaches the set stopping diameter, the alarm will buzz upand the built-in relay will be energized immediately and output a signal for externalcontrol.
