Conveyor Belt conveyor system is the key equipment, security and stability of its direct impact on production operations. Conveyor Belt deviation is the most common faults, their timely and accurate processing of its safe and stable operation of the protection. Deviation of the phenomenon and the reasons are many, according to the different phenomena and causes of deviation adjusted to take a different approach, in order to effectively solve the problem. This article is based on years of field practice, from the user point of view, the use of mechanics analysis and explanation of such failure causes and treatment.
First, bend the head or tail drive pulley and the conveyor roller axis is not perpendicular to the centerline, resulting in the head drum or belt bend pulley at the tail deviation. Roller deflection, the belt tightness on both sides of the drum is inconsistent along the width direction of the traction suffered Fq also inconsistent, as increasing or decreasing trend, which would make a belt attached to the moving direction of decreasing force Fy , leading to the loose side of the belt deviation, the so-called “run do not run loose tight.” The adjustment method as follows: For the head drum, such as the right Conveyor Belt to the drum deviation, then the right side of the bearing seat should be moved forward, the left Conveyor Belt to the drum deviation, then the left side of the bearing seat should be forward move, the corresponding bearing can also be left or right side of the bearing after shift after shift. Rear roller adjustment method and the head drum is just the opposite. After repeated adjustments until the Conveyor Belt transferred to a more ideal location. Adjust the drive or bend pulley in the best pre-install its exact location.
Second, the outer surface of drum processing errors, sticky material or uneven wear caused by diameter sizes, Conveyor Belt to the larger diameter side of the deviation. So-called “big run to run small.” Its force as shown in Figure four: traction Fq produce a Conveyor Belt to move the large diameter side of the pitch Fy, Fy role in the pitch, the belt shifted. In this case, the solution is to clean the drum surface of the adhesive material, processing errors and uneven wear down the re-processing package will replace the plastic handle.
