firstly, when in transmission, a limiting wheel (16) is contacted with the inner wall of a wheel groove (17), a driving motor arranged outside a transmission frame drives two driving shafts (3) to rotate, the two driving shafts (3) drive a transmission belt (4) to rotate, mineral transmission can be carried out at the moment, in the process, one side of a displacement sensor (24) is lapped on the outer side of a limiting belt (5), when the transmission belt receives offset force or weight is uneven, the limiting belt (5) receives offset force to move outwards, the displacement sensor (24) in the offset direction receives pressure to move, and at the moment, the displacement sensor (24) transmits signals to a controller and controls a forward-reverse motor (26) to rotate;
when the conveyor belt (4) deflects to the left, the output end of the forward and reverse rotating motor (26) rotates clockwise, the forward and reverse rotating motor (26) drives the wire rod piece (27) to rotate on the two limiting rings (28), the left worm (272) rotates and can drive the two bevel rings (31) on the left to rotate, at the moment, the bevel rings (31) drive the second wire sleeve (30) to rotate in the first fixed ring (29), at the moment, the two lifting screw rods (32) rotate and move in opposite directions, when the lifting screw rods (32) rotate, the epitaxial screw rods (33) drive the first wire sleeve (34) to move upwards, at the same time, the left end of the positioning inclined rod (8) on the left moves upwards and rotates in the sliding groove (7), so that one end of the positioning inclined rod (8) is loosened between the movable frames (9) hinged, the limiting wheels (16) arranged on the movable frames (9) are separated from contact with the wheel grooves (17), and when the right end of the screw rod piece (27) rotates, the two lifting screw rods (33) move in opposite directions, the two wire rods (34) move downwards relative to the opposite directions of the positioning inclined rod (8), the limiting wheels (16) arranged in the movable frame (9) apply pressure to the wheel grooves (17) to enable the limiting wheels (16) to pull the limiting belt (5) moving to the right side, so that the running stability of the conveying belt (4) can be ensured, when the conveying belt (4) deviates to the right side, the output end of the forward and reverse rotating motor (26) rotates anticlockwise, the forward and reverse rotating motor (26) drives the wire rod pieces (27) to rotate on the two limiting rings (28), and at the moment, the left limiting wheels (16) apply pressure to the wheel grooves (17) to enable the limiting wheels (16) to pull the limiting belt (5) moving to the right side to the left side;
thirdly, performing the following steps; in the second step, due to the fact that the idle rotation and the deviation of the conveyor belt (4) occur when the conveyor belt becomes loose, the operation is only to rectify the rotation of the conveyor belt, in the second step, when the forward and reverse rotation motor (26) rotates, the two third wire sleeves (315) move on the first screw rod (273) and the second screw rod (274) respectively, when the first screw rod (273) and the second screw rod (274) rotate, the two third wire sleeves (315) move towards opposite directions, at the moment, two ends of the hinged connecting rod (318) rotate on the rotating rod (314) and the hinged seat (317) respectively, at the moment, the two transverse hinged connecting rods (318) can prop up the fixed shaft rod (310) outwards, so that the two auxiliary shafts (309) move to the inner cavity of the containing groove (304) to apply tension force to the conveyor belt, and in the process, the conveyor belt (4) can be guaranteed to be in a tensioned state in operation under the condition that the deviation occurs.
