Description
Technical Field
The utility model relates to a material conveying equipment technical field, concretely relates to make conveyer belt automatic centering mechanism.
Background
Belt conveyors are devices that are widely used in material handling. The belt often appears the off tracking phenomenon in the operation process, causes the wearing and tearing of belt edge, appears the serious accident such as cassette or belt tear, influences production operation. The main reason for this is due to conveyor installation errors; the long-term use causes the deformation of the frame; belt bonding errors; and unbalance loading during material conveying and the like. At present, the belt deviation problem is mainly solved by stopping the machine for maintenance and adjusting the angle of a belt driving roller or a tensioning roller to correct the deviation of the belt. After the centering-adjusted belt is used for a period of time, the belt is deviated again due to the reasons of heavy-load transportation, uneven stretching of the belt and the like. And the machine is stopped repeatedly to adjust manually or adjust the driving or tensioning roller manually and continuously, so that the belt is centered. Of course, the method for automatically adjusting the belt deviation electrically or pneumatically adopted in the food and textile industries is expensive and has requirements on the use environment.
As described in patent CN202988075, CN201411237, fixed rollers are installed on frames on both sides of the belt conveyor, and when the belt deviates, the side shift of the belt edge is blocked, this method can only block the belt deviation for a short time, cannot adjust the belt centering, and causes the abrasion and damage of the belt edge. Also, for example, U.S. patent nos. 5,950,806, 2,725,757, etc. disclose self-aligning idler devices. In order to solve the problem of manually and frequently adjusting the off tracking belt, an aligning carrier roller is arranged at the lower part of the conveyor. When the belt deviates during movement, one side of the belt is in contact with the vertical wheel of the aligning carrier roller and applies a large force, so that the aligning carrier roller rotates along the pivot, and the central line of the belt is adjusted back to the center of the conveyor. The effect of belt deviation adjustment is achieved.
The aligning idler described in the above patents has been found to present some problems: firstly, because be equipped with perpendicular vertical wheel on aligning bearing roller both sides for the mechanism is great, and the perpendicular vertical wheel receives the incessant deflection of the extrusion of belt, in order to reduce the injury to personnel, the frame outer casing of conveyer will widen and wrap aligning bearing roller mechanism inside, has increased the width of conveyer. Secondly, the mechanism is huge, a large installation three-dimensional space is needed, and special installation requirements are required for the rack. In addition, the vertical pulley and the edge of the belt are abraded seriously, so that the belt is damaged.

Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): as shown in fig. 1-6, an automatic centering mechanism for a conveyor belt comprises a conveyor frame 1, a conveyor belt 2 is arranged on the conveyor frame 1, and an automatic centering assembly 3 is arranged between the conveyor belt 2 and the conveyor frame 1. Automatic centering subassembly 3 includes link 7, be equipped with 2 between link 7 and conveyer belt 2 and link 7 both ends looks pin hub connection fixed just be equidistant distribution's unpowered roller 4, unpowered roller 4 includes cylindrical tube 12, be equipped with in the cylindrical tube 12 with link 9 upper ends looks articulated joint formula of looks plug-in connection fixed roller axostylus axostyle 10, cylindrical tube 12 both ends are equipped with and are integration with axle center welded fastening and with the circular cone body 11 that the roller axostylus axostyle 10 cup jointed mutually with cylindrical tube 12. The inclination angle of the outer wall of the conical pipe body 11 is 1.2-1.5 degrees, and the optimal inclination angle is 1.4 degrees. A chassis 8 is arranged between the connecting frame 7 and the conveyor frame 1, and a chassis supporting shaft 5 which is in through nested connection with the upper end of the connecting frame 7 is arranged on the chassis 8. A pair of symmetrical positioning baffle shafts 6 which are movably contacted with the connecting frame 7 are arranged at the front end and the rear end of the connecting frame 7, and the positioning baffle shafts 6 and the chassis supporting shaft 5 are integrally and vertically welded and fixed. A plurality of connecting frame universal wheels 9 are arranged between the lower ends of the two sides of the connecting frame 7 and the chassis 8, and the upper ends of the connecting frame universal wheels 9 are fixedly connected with the unpowered roller 4 in an inserting and embedding manner through hinged joints.
When the conveyor runs normally, the conveyor belt 2 is in the central area of the conveyor frame 1, the traction force borne by the conveyor belt 2 overcomes the resistance of the unpowered roller 4 to the conveyor belt 2, and at the moment, the unpowered roller 4 rotates towards the running direction of the conveyor belt 2.
When the belt moves to one side, the traction force of the unpowered roller 4 along two sides of the central line of the conveyor frame 1 generates a magnitude difference, so that the unpowered roller 4 drives the connecting frame 7 to roll on the chassis 8 through the connecting frame universal wheel 9 and simultaneously rotate around the chassis supporting shaft 5; so that the axis of the unpowered roller 4 forms an included angle smaller than 90 degrees with the central line of the conveyor frame 1. The inclined unpowered roller 4 generates thrust which enables the central line of the conveyor belt 2 to coincide with the central line of the conveyor frame 1 in the rotation process, and the forces applied to the two sides of the chassis supporting shaft 5 by the conveyor belt 2 are born by the inclined unpowered roller 4 and tend to be equal continuously, so that the automatic centering effect of the belt is achieved.
To sum up, the automatic centering mechanism for the conveyor belt has the characteristics of simple structure, good operation stability, good sustainable use performance and small occupied space. The problem of easily causing wearing and tearing to the belt edge is solved. Avoiding shutdown or frequent manual maintenance and adjustment.
