A common treatment methods of belt conveyer belt running deviation

1. Conveyor roller adjustment
Belt conveyor in central position appeared running wide adjustable roller position to adjust the running deviation; Belt rollers on both sides of the mounting holes should be oval, convenient adjustment .When the belt to which side wandering, then adjust the roller in the lateral direction toward the belts moved forward, backward or another side.

2. Install the self-aligning roller group
Self-aligning roller group has intermediate shaft type, four connecting rod type, vertical roll type and other types. Its principle is when the belts running deviation deflect driven self-aligning roller group, make the roller produces a prompted the friction tape restore equilibrium position, so as to achieve the aims of rubber belt adjustment.

3. The driving drum and redirection roller adjustment
Driving drum of belt conveyor and the adjustment of the redirection roller is one of the belts running deviation adjustment method. All roller installation location must be perpendicular to the centerline of the direction of the length of the belts conveyor, if excessive deflection must be deviation, and the adjustment is similar with roller group. To head to the rights side of the drum, such as belt running deviation, the bearing should move forward, on the right side of the belts to the drum of the lefts side of the wandering, is on the lefts side of the bearing should be moving forward, can also be on the lefts side of the corresponding bearing seat back or on the rights side of bearing seat back. The tail roller adjustment method is contrary to the heads roller.

4. The adjustment of the belts tightness
Belt is the regulation of elastic belt conveyor running deviation adjustment important method. Two upper heavy hammer redirection rollers besides belt length should be perpendicular to the direction should be perpendicular to the gravity vertical, which ensure the shaft centerline. Using spiral elastic or tightness of the hydraulic oil cylinder, the two elastic roller bearing should translation at the same time, to ensure that the cylinder axis and the vertical belt longitudinal direction. The specific belt running deviation adjustment method is similar with roller.

5. Transfer point blanking position influence on belt running deviation
Transfer point material blanking position has a very large effect on the belt running deviation; especially in the two belt conveyor in the horizontal plane projection into vertical impact is bigger. Usually should consider transfer points up and down two relative heights of belt conveyor Relative height is lower, the greater the horizontal velocity component of the material, on the lower belt lateral impact is bigger, the material is difficult to center at the same time. Make the materials on the belt cross section deflection, eventually led to the belt running deviation. If the material slants to the right, the belt running deviation,if the left and the vice versa. In the design process should be as much as possible to increase the two relative height of belt conveyor. In the limited space of up and down movement of bulk material conveying machinery funnel, feed trough should seriously consider such a form and size. General feed trough of the width of about two-thirds of the width of the belt is more appropriate. To reduce or avoid the belt running deviation can increase the keep-off plate block material, change the direction of the whereabouts of the material and location.

6. Two-way adjustment of deviation of belt conveyor running operation
Two-way running of belt conveyor belt running deviation adjustment than one-way belt conveyor running deviation of a much more difficult, in the concrete adjustment should be first in one direction, and then adjust the other direction. Adjustment should observe carefully when belt movement direction and trend of running deviation, the relationship between one by one. The emphasis should be on the adjustment and haul driving drum, followed by the adjustment of the roller and the material of blanking point adjustment. Belt should be paid attention to and should make the belt when vulcanization joint force uniform, and the section length direction when using leading chain traction force on either side of the equal as much as possible.
