Adhesive tape longitudinal tearing and deviation detection device

The utility model discloses a longitudinal tearing and deviation detection device for an adhesive tape. The longitudinal tearing and deviation detection device is characterized by comprising a base, a clamping rod and an alarm circuit, the base is installed at the roller way gap position of the rubber belt conveyor. The two clamping rods which relatively move in a reciprocating mode are vertically arranged on the base, and the displacement direction of the clamping rods is perpendicular to the conveying direction of a conveying belt of the rubber belt conveyor; the two clamping rods are located on the two sides of the belt face of the conveying belt correspondingly, and rod bodies of the clamping rods are attached to the edges of the conveying belt. A spring for enabling the two clamping rods to move relatively is arranged on the base; the operation condition of the belt conveyor is judged through the detection device, and then an alarm is directly given when a fault occurs, so that an operator is prompted to
