As shown in fig. 1 and 7, the deviation detecting mechanism is symmetrically located on both sides of the conveyor, and is configured such that the bottom ends of the vertical rollers 9 of the vertical rollers are fixedly arranged on the sliding blocks 20, the sliding blocks 20 are in sliding fit with the transverse guide rails 18, and when the belt 21 that is deviated abuts against the vertical rollers 9, the vertical rollers 9 can be displaced laterally outward along the transverse guide rails 18.
As shown in fig. 1 and 2, the deviation-correcting linkage mechanism transmits the lateral displacement to the idler assembly and pushes the idler assembly to rotate around the central rotating shaft 14 at a deviation-correcting angle at a corresponding side.
As shown in fig. 1, 4 and 5, in this embodiment, the deviation rectifying link mechanism is configured as a force amplifying link, and a three-rod structure is formed by a driving rod 10, an actuating rod 11 and a link 12, first ends of the rods in the three-rod structure are hinged together, the driving rod 10 is located at a position parallel to the transverse guide rail 18, a second end of the driving rod 10 is hinged to the slider 20 and is in transverse linkage with the slider 20, and a second end of the actuating rod 11 is hinged to the middle of the linkage bracket 7 and is used for driving the idler assembly to rotate around the central rotating shaft 14 through the linkage bracket 7; the second end of the connecting rod 12 is hinged on the connecting rod bracket 17, and the connecting rod bracket 17 is fixedly arranged on the corresponding position of the conveyor frame, so that the driving rod 11 and the connecting rod 12 form an obtuse angle.
In the specific implementation, the corresponding measures also comprise:
as shown in fig. 1 and 3, the end bearing 5 is a deep groove ball bearing, the end bearing 5 is supported on the end bearing seat 4, and the end bearing seat 4 is fixedly installed on the movable bracket 2.
As shown in fig. 2 and 4, the central rotating shaft 14 is supported by the upper and lower cylindrical roller thrust bearings 13, and the upper and lower cylindrical roller thrust bearings 13 are respectively provided in the cylindrical roller thrust bearing seats 6 at the corresponding positions.

When the belt pitch deviation touches the vertical roller 9 on one side and generates lateral thrust to the vertical roller 9, the slide block 20 slides outwards along the transverse guide rail 18 to generate transverse displacement, and the driving force acts on the second end of the driving rod 10 in the three-rod structure to enable the three-rod structure to form a force boosting mode, so that the carrier roller assembly is pushed to rotate through the linkage support 7 until the vertical roller 9 stops displacing, the carrier roller assembly is locked at a rotated angle position, and the belt is pushed to reset by using the friction force generated between the carrier roller deviation and the belt, so that deviation rectification is realized.
When the belt is normally conveyed, the vertical roller 9 is not contacted, the active force acts on the second end of the execution rod 11 in the three-rod structure, so that the three-rod structure forms a force reducing mode, and under the action of friction force, the carrier roller assembly is locked on the fixed base 1 and cannot freely rotate, and the belt conveying stability is guaranteed.
