Why does the belt conveyor deviate at the tail? In the process of belt running, the center line deviates from the center of the conveyor, which is the belt deviation. Deviation of conveyor belt is a common fault of conveyor. It is easy to cause material spilling after deviation, and the material spilled will fall on the non working surface of conveyor belt below. After running, it will reach the tail of conveyor, resulting in material accumulation at the tail, resulting in deviation of conveyor belt and tail roller.

1、 The deviation correction idler is installed before the tail roller of the return section.

When the conveyor belt deviates from the center, the conveyor belt contacts with the inspection and driving wheel, which drives the drive pump to press. Through the logic valve group in the program control station, the piston rod of the angle adjusting cylinder expands and contracts to drive the linkage correction idler to deflect according to the set direction. At this time, the linear movement direction of the adjustment idler forms an angle with the movement direction of the conveyor belt, and the friction generated between them drives the conveyor belt to move again In order to achieve the purpose of random automatic correction of conveyor belt deviation.

2、 Spreading and stacking can improve the loading and transportation conditions of the discharge chute. The materials transported by the conveyor belt are often sticky, such as coal, mud and powdery materials. After the normal unloading of materials, a small amount of materials will adhere to the surface of the conveyor belt and cannot be completely disposed of.

With the conveyor belt running for a long time, more and more materials will accumulate, the conveyor belt will run unevenly, which is easy to cause the conveyor belt deviation. Therefore, it is particularly important to remove viscous materials in time and install ritclean air cleaner. Ritlean empty section cleaner is suitable for cleaning sticky materials on non working surface of conveyor belt. The cleaning scraper is made of polyurethane material. The blade is wear-resistant, anti-corrosion, and does not damage the conveyor belt. It has high safety performance.

The parallel structure frame can make the sweeper close to the conveyor belt, and can automatically adjust the position of the sweeper according to the wear condition of the cleaning blade and the position change of the conveyor belt. The cleaning is clean and effective, the structure is simple, and the maintenance is convenient.

3、 The idler or roller is not aligned with the center line of the conveyor belt. Adjust the idler in the deviation area. When adjusting, carefully observe the relationship between the running direction of the conveyor belt and the deviation trend, and adjust item by item. After adjustment, if there are still problems, check whether the belt is evenly stressed, and check the belt joint and tensioning device.

Generally, the tail roller is lubricated with rolling bearing and grease, so the sound is small and the operation is stable. When the abnormal sound occurs, the bearing is usually short of oil or damaged. The abnormal sound is sent to the bearing seat and accompanied by the bearing seat heating. At this time, oiling the bearing or replacing the bearing can prevent the conveyor belt from running away.

On the conveyor belt conveyor in the tail of why the deviation, conveyor belt manufacturers for you to this. If you are interested in conveyor belt, welcome to inquire.
