Automatic anti-torsion device of round pipe belt conveyor

The invention discloses an automatic anti-torsion device for a circular tube belt conveyor, which comprises a support frame, a circular tube conveying belt and a plurality of PSK plates positioned in the support frame, and is characterized in that a plurality of correction assemblies are respectively arranged on two sides of each PSK plate, and the correction assemblies are controlled by a correction system; a plurality of image acquisition devices are distributed on an easy-to-twist part along the circumference of the circular pipe conveying belt, when the circular pipe conveying belt twists, the shape of a circular pipe changes accordingly, the image acquisition devices acquire changed data and send the data to a control module, the control module analyzes the data and judges the twisting direction and angle of the conveying belt, and the twisting direction and angle of the conveying belt are judged. And a corresponding instruction is sent to the driving unit according to a preset value obtained by the corr
