A material flow interruption detection device for use in a belt conveyor process

Abstract

The utility model discloses a material flow break detection device for the process of adhesive tape transportation, include: mount, set up on adhesive tape conveyer, detection rod, rotatable setting in the middle part on mount, its head and the surface of the conveyer belt of adhesive tape conveyer contact, detect switch, set up on the storage warehouse lateral wall of adhesive tape conveyer, wherein, the movement track of detection rod tail can coincide with the position of the cam of detect switch, the signal output end of detect switch is connected with PLC or DCS control system. The utility model is with the help of the powder material in adhesive tape transmission, and the material height is formed on the adhesive tape, makes the head of detection rod to lift up, and the tail of detection rod presses the cam of detect switch, and detect switch exports the closed signal, and this is the normal state of adhesive tape conveying material. When there is no material on the adhesive tape, the detection rod is downward due to the effect of the weight, and the rear end of the detection rod moves upward, and the detect switch exports the open signal, and this is the flow break state of adhesive tape conveying material.
