Belt deviation is a common problem in the operation of belt conveyor, but it is easy to solve such problems as long as reasonable treatment is adopted. Installation of aligning roller group. The use of self-aligning roller group is an effective method to solve the problem of belt conveyor belt deviation. For the aligning idler group, the principle is the same whether it is the middle rotating shaft type, the four-bar type or the vertical roll type. The purpose is to make the belt automatically centrifugal, so that the deviated belt can be adjusted. Generally speaking, the belt conveyor is relatively short, its deviation problem is more common, and the solution is relatively complex. The effect of this method is better. In addition, when the belt conveyor runs in two directions, the effect of this method is also good. It is noteworthy that this method is not suitable for long belt conveyor, and will bring adverse effects on the service life of belt, adjusting the position of driving drum and improving drum, which is an important means to solve the problem of belt deviation. In a belt conveyor, there are at least 2 to 5 drums. Of course, there is no need to distinguish between driving drums and directional drums, but there is one thing in common, that is, the installation position of drums must be perpendicular to the center line of the belt conveyor, and more specifically, to the center line of the length direction. If these two directions are inclined to a large extent, the problem of running deviation is unavoidable.

The specific method of adjusting the driving drum and the reversing drum is that for the head drum, if the belt deviates to one side of the drum, the bearing seat of the coating line of the pneumatic transmission shaft on that side should move forward. Similarly, the bearing seat on the non-deviating side can also be moved backward. The tail drum adjustment method is exactly the opposite. In order to adjust the belt to a more appropriate and accurate position, it usually needs repeated adjustments. In addition, for driving or reversing drum, it is necessary to accurately locate the blanking position at the reloading point, which is also an important factor affecting belt deviation. From the actual production point of view, when the position of the two belt conveyors in the horizontal direction is special, such as when the projection of the two conveyors is perpendicular to each other, this effect is greater. Generally speaking, it is necessary to pay great attention to the relative position of two belt conveyors at the transfer point. From the point of view of velocity vector, the lower the relative height, the greater the horizontal velocity of the material, and the greater the impact force on the lower belt, * eventually leads to the belt deviation. If the material deviates to which side, then the belt deviates to the opposite side. Therefore, in the design process, this problem should be considered and solved to avoid the relative position between the two belt conveyors as low as possible. Usually, the width of the guide groove should be appropriate. The value should not be too large or too small. Generally, it is 2/3 of the width of the belt. At the same time, it can change the direction and position of the material falling, thus reducing or avoiding the deviation of the belt.
