Rewound tape and broken tape capturing device of belt conveyor

The utility model relates to a rewound tape and broken tape capturing device of a belt conveyor. The rewound tape and broken tape capturing device comprises a self-locking device which comprises a bracket, a middle roller, eccentric rollers and a brake device, wherein the middle roller and the two eccentric rollers are arranged on the bracket; the two eccentric rollers are arranged at the two sides of the middle roller; the brake device comprises a brake beam, a gate block, a regulating bolt, an anti-deviation bolt, an anti-deviation vertical roller, a detecting switch and a spring, wherein the brake beam is connected to the eccentric roller; the gate block is arranged at the front end of the brake beam through the regulating bolt; and the anti-deviation vertical roller is arranged between the brake beam and the eccentric roller. The rewound tape and broken tape capturing device of the belt conveyor can be arranged at multiple points along the line to solve the problem that the belt-breaking points are randomly distributed, the brake force is greater than 5 tons and the reaction time is less than 0.5 seconds. The rewound tape and broken tape capturing device can be used for debugging without breaking the tape, improving the working stability and preventing the conveyor belt from deviating.
