Product Details

The longitudinal tear protection device consists of two parts: a sensing box and a control box. The sensor is the detection element for longitudinal tear. When the tape is torn during operation, the sensor can reliably detect it and output a switch value. The control box receives the signal from the sensor, controls the relay to operate, and outputs a switch value to the control room to achieve automatic emergency stop. At the same time, the panel alarm indicator flashes, and the control circuit locks. To restore the control circuit to normal, the reset button on the panel can be pressed. In addition, there is a self calibration button on the panel. When this button is pressed, it can simulate a tearing fault and verify the operation of the control system.

Longitudinal tearing is used for the protection of belt conveyor belts from longitudinal tearing. The sensor is installed under the tape and will sound an alarm when the tape is scratched or damaged by foreign objects. Longitudinal tearing of the tape is a malignant accident, and allowing it to develop will cause serious losses. This series can continuously monitor the operation of adhesive tape, and when a longitudinal tearing fault occurs, it can promptly issue a shutdown signal to prevent the fault from expanding

Tear switches are installed in pairs on the conveyor belt and connected by two steel wire ropes. One end of the steel wire rope is fixed on the support bracket, and the other end is connected to the pull ring of the tear switch. The two sections of steel wire rope form a monitoring surface under the conveyor belt. When an object or torn belt is suspended and falls onto the wire rope, the wire rope pulls the tear switch pull ring to activate it, and the tear switch sends out or stops the machine signal.
