The deviation of the conveyor belt is a common problem encountered during the use of the conveyor, and it is also a headache for customers. How to prevent and eliminate the misalignment of the conveyor belt? It is necessary to check the causes first, and then "medical treatment". I. Preventive measures for conveyor belt deviation (1) Improve installation quality (2) Improve conveyor belt joint quality; (3) Strengthen patrol inspection and maintenance (4) Ensure unbiased loading; (5) Ensure that the cleaning device is normal. Second, on-site processing method of conveyor belt deviation (1) Automatic drag roller deviation adjustment: When the deviation range of the conveyor belt is not large, the self-aligning drag roller can be installed at the deviation of the conveyor belt. (2) Appropriate tightening and deviation adjustment: When the conveyor belt runs sideways, the irregular direction indicates that the conveyor belt is too loose, and the tensioning device can be properly adjusted to eliminate the deviation. (3) Single-sided vertical roller deviation adjustment: The conveyor belt always deviates to one side. Several vertical rollers can be installed within the range to reset the tape. (4) Adjusting the deviation of the rollers: the conveyor belt is running away from the rollers, checking whether the rollers are abnormal or moving, adjusting the rollers to the horizontal position to rotate normally to eliminate deviations, (5) correcting the deviation of the conveyor belt joints; Always one direction, and the maximum deviation is at the joint. The conveyor belt joint can be corrected perpendicular to the centerline of the conveyor to eliminate deviation. (6) Paddle roller adjustment: The deviation and direction of the conveyor belt are constant. Several sets of side rollers are used to eliminate the deviation. (7) Adjusting the deviation of the trailing rollers: The deviation direction of the conveyor belt is constant. Check that the centerline of the trailing rollers is not perpendicular to the centerline of the conveyor belt. You can adjust the trailing rollers to eliminate the deviation. (8) Elimination of attachment deviation: The deviation point of the conveyor belt remains unchanged. If attachments are found on the tow rollers and rollers, the deviation should be eliminated after removal. (9) Correct the deviation of the feeding: The tape is not biased at light load and the deviation of heavy load. The feeding weight and position can be adjusted to eliminate the deviation. (10) Correcting the deviation of the bracket: The deviation direction and position of the conveyor belt are fixed, and the deviation of the bracket can be adjusted to prevent the deviation.
