What are the methods to adjust a belt conveyor that has shifted out of alignment?

Off track? Could you describe it more clearly? Our belt conveyors are equipped with adjustment bolts on both sides, and the issue can be easily resolved by adjusting the length of these bolts

How long is the belt in total? The shorter the belt, the harder it is to adjust. It can be adjusted by changing the positions of the electric drum and the tail drum. If the belt is long, simply adjust the head and tail rollers; a vertical guide roller is used in the middle to prevent deviation ； The prerequisite is to ensure that the belt bracket remains as straight as possible.

It is necessary to check whether the short idler rollers on the conveyor belt, as well as the upper and lower self-aligning idler rollers, are damaged or not installed; generally speaking, this is true unless the conveyor belt is very easy to adjust. Give it a try

Could you be more specific? You’re not clear about which type of equipment the conveyor belt belongs to; I don’t know where to start. First, check whether the belt frame is straight, whether the four corners of the conveyor belt are properly secured, whether the conveyor belt is at a right angle to the belt frame, and whether the belt rollers are severely worn out

It depends on the length of the belt; for a shorter belt, adjust the tail roller； Adjust the adjustment roller on the long belt tensioner.

Possible causes of deviation and correction methods: The tape deviates locally from a certain point; the center of the idler roller is not aligned； The idler roller is not rotating ； The surface of the roller is uneven; clean and replace the idler rollers. Move the idler rollers on the side where there is deviation forward, as this causes the entire conveyor belt to deviate to one side. If the rollers are not parallel, the belt will deviate to the side where it is looser (it moves more in the loose direction rather than the tight one). Adjust the rollers; if the tensioning mechanism is not functioning properly, tighten the relevant screws accordingly. If the diameters of the rollers are inconsistent, the belt will deviate to the side with the larger diameter (it moves upward rather than downward). If the problem lies in the manufacturing of the rollers, then they need to be properly processed and adjusted ； If the material is sticking to the surface of the drum, the drum surface should be cleaned. If the frame is not properly aligned and sways from side to side, the frame should be corrected or reinforced. If the entire belt is skewed to one side, with the greatest deviation occurring at the joints, the belt joints need to be adjusted properly. Skewing occurs when there is load, but not when there is no load. Improper feeding or uneven loading can also cause this issue; if it’s not possible to resolve improper or uneven feeding, measures such as adjusting the position of the feed chutes or installing self-aligning idlers can be taken. If the belt is damaged, partial skewing may occur – damage to the edges of the belt results in different frictional forces on each side, so the belt should be repaired or replaced promptly. If the new belt still skews, it may be because it’s too thick, resulting in poor tracking; this issue can usually be corrected after using it for some time

As clearly stated upstairs, those who agree with him say that if the canvas belt gets wet, it too tends to shift out of place

Adding a suspension under the belt serves as a roller counterweight; this can solve the problem if the deviation is not too severe.

1. The idlers should be symmetrical left and right, and the drums should be parallel front and back. 2. Vertical guide rollers should be installed on both sides of the belt to prevent it from drifting

Infrared alignment: infrared probes and receiving devices are used to detect deviation, after which the parallelism of the two rollers is adjusted

In addition to what was mentioned on the 11th floor, adjustment is also possible through the left-right movement of the idlers, and the movement of these idlers is controlled by air bags.

There’s no major issue; a few guide rollers on each side can be used for alignment, and a few support rollers with circular guards welded to their sides will do

It’s difficult to adjust if the belt is too short. Adjustment method: 1. Adjust the adjustment screw of the belt idler wheel. Adjust the side where the belt is skewed. When adjusting, turn the screw inward. 2. Pay attention to keeping the belt clean and hygienic. 3. Check whether the belt idlers are in good condition. 4. Check whether the belt is in good condition. 5. Check whether the reducer or electric drum is in good condition. 6. Check the anti-deviation wheels on both sides of the belt. 7. Check the pressure belt wheel.
