-Off with the arrest Installation Instructions broken belt protection

product description

DDZ or ordinary steel strong type of rack, hanging off the belt conveyor belt protection.
Currently on the market sold off with the arrest of the belt is. Most eccentric roller line contact arrest belt, while off DDZ series conveyor belt is a surface contact arrest arrest belt

working principle

On tape-off with the arrest device (DDZ-S type)

Belt conveyors in normal operation, belt under arrest the brake blocks contact with the belt, and can backstop roller rotate with the belt. When breakage occurs belt containing material belt sagging decline, the pressure in breaking Hanging can and left and right sides of the plane of the brake brake block to wedge along the track of rapid oblique displacement, gradually narrowing the distance between the brake block backstop rollers, with the arrest, eventually arrest the decline belt grip. At the same time downward slide hanging backstop roller can trigger a flameproof sensor, outwardly passive contact signal output with a broken alarm.

Tape off the belt under arrest devices (DDZ-X type)

Belt conveyors in normal operation, the lower belt is not in contact with the lower brake blocks and eccentric rollers when breakage occurs belt, mounted beneath the upper belt of power arm force decline, driven by a connecting rod mechanism, springs, pins consisting of The rapid release of eccentric rollers, the eccentric roller and the tape running in the same direction, so that the gap under the brake block and the eccentric roller diminishing quickly arrest the tape. alarm outwardly passive contact signal output with a broken alarm.
