How to solve the belt conveyor deviation?

Deviation conveyor belt conveyor is the most common faults, its timely and accurate processing is to protect its security and stability operation. Many phenomena and causes of deviation, to take a different method of adjusting deviation phenomenon and according to different reasons, in order to effectively solve the problem.

Analysis and explanation of such failure causes and treatment methods:

(1) driving the drum head or tail bend pulley axis is not perpendicular to the centerline of the conveyor, resulting in the deviation conveyor bend pulley at the head or tail drum, the drum deviation on either side of the belt tension in the drum degree of inconsistency, along the width direction of the traction force Fq also inconsistent suffered, to increment or decrement the trend which would make a decrement additional conveyor belt moving direction of the force, leading to the loose side of the belt deviation, the so-called "run loose do not run tight ", the adjustment method for the head pulley conveyor belt deviation to the right side of the drum, the bearing seat on the right side should be moved forward, the belt deviation to the left side of the drum, the left bearing seat should be moved forward, corresponding to the left can also be moved after the bearing or bearing on the right shift. Rear roller adjustment method and the head drum opposite. After repeated adjustment until the belt tuned ideal position adjustment before driving or redirecting roller Simply the best install its exact location.

(2) Simple roller outer surface machining error, sticky material or wear caused by uneven diameter sizes, the belt deviation to be larger diameter side. In this case the solution is to clean the surface of the drum stick materials, processing errors and uneven wear to be replaced down reprocessed plastic bag handling.

(3) reproduced point blanking malposition, blanking position has a very big impact on the conveyor belt deviation, especially on the bar conveyor and the conveyor section in the horizontal plane of projection perpendicular to a greater impact. Gao generally should consider the relative degree reprint point up and down two belt machine. The relative height of the lower horizontal velocity component material larger side of the lower belt of the greater impact, but the material is difficult to center. So that the cross section of material on the belt skew, if the material is biased to the right side of the belt deviation to the left, and vice versa. For deviation in this case, in the design process should increase the relative height of two conveyors as possible. In the space constraints of the vertical belt conveyor hopper, chutes and other parts of the form and size should seriously consider. General guide chute width should be about three-fifths of the width of the belt is more appropriate. To reduce or avoid the belt deviation can be a barrier to increase in the striker plate material, changing the orientation and position of the whereabouts of the material.
