Deviation of the conveyor belt is one of the common problems in working with this equipment, which can have an adverse effect on their performance and efficiency. Conveyor belt is a practical device in the field of moving and transferring materials and goods, which is used in many fields of work, especially in industries. These devices are available in different types and dimensions so that they can be used in different working conditions. Working with conveyors will increase operational speed, work efficiency and reduce costs, and will greatly help increase the safety of the operational system and its employees.
Conveyor belts may deviate due to random reasons, periodic reasons and permanent reasons, each of these reasons will be affected by a series of factors. Considering the high impact of conveyor belt performance on the work process and the importance of adjusting it in different working conditions, in this article we intend to introduce the causes of conveyor belt deviation and the factors affecting them, and the necessary inspections to detect the deviation and fix it. Finally, let’s mention the ways to prevent the deviation of these devices.
Accidental causes of conveyor belt deviation
Among the accidental causes of conveyor belt deviation, we can point out the foreign object stuck in the device, environmental conditions, and material stuck to the money, which we will introduce below.

A foreign object is stuck in the device
Among the factors that cause the conveyor belt to deviate, it can be mentioned that foreign objects are stuck in these devices. As long as the conveyor belt has a good performance, the edges of the belt will continue to move without contacting the two sides of the machine, and the presence of foreign objects in the structure of the machine can cause the edges of the belt to get involved and eventually the conveyor belt to deviate.
Environmental conditions and their effect on conveyor belt deflection
Environmental conditions can be mentioned among other factors affecting the deviation of the conveyor belt that is related to its use in the open space. Wind, sunlight, snow and rain, etc. are among the environmental conditions that can affect the performance of the conveyor belt and cause it to deviate. Wind can upset the adjustment of the conveyor and cause it to deviate. Of course, the amount of deviation of the conveyor belt in such a case depends on the intensity of the wind, the angle of the wind, the width and weight of the belt, the weight of the transfer material, etc.
On the other hand, sunlight on the conveyor belt causes one side to stretch compared to the other side, which will cause the conveyor belt to deviate. On the other hand, snow and rain on the surface of the belt causes a change in the friction of the surface in contact with the transfer materials, which increases the possibility of the conveyor belt deviation.

Materials attached to the money
Material adhering to the pulley, especially on one side of these components, can provide a platform for conveyor belt deflection. The pulleys are cylindrical and symmetrically designed to help the belt perform optimally during material transfer. However, material sticking to one side of the pulleys can change this cylindrical and symmetrical structure and cause the conveyor belt to deviate.
Periodic causes of conveyor belt deviation
The periodic reasons for the deviation of the conveyor belt itself include various cases, including improper snap and tension adjustment, off-center loading of the belt, deviation of the conveyor belt due to incorrect splices and improper conditions of the conveyor belt, which are further introduced They will pay.
According to the jolodaconveyorserviceswebsite, mistracking, belt slippage, seized rollers and blockages are all common conveyor problems that prevent systems from operating efficiently. Without the necessary intervention, conveyor problems like this can lead to catastrophic failure and significant downtime.
Improper adjustment of monetary snap and tension
Among the reasons that cause the deviation of the conveyor belt, it is possible to point out the improper adjustment of the snap and tension, which is included in the category of periodic reasons for the deviation of the conveyor belt. In the usual case, the axis of these two should be perpendicular to the movement axis of the belt, and their incorrect adjustment can be associated with the tightening or loosening of the belt and ultimately the deviation of the conveyor belt.

Conveyor belt eccentric loading
Among the other things that need to be paid special attention to when working with conveyor belts is concentrated and vertical loading of materials so that the belt has a good performance during movement. Now, if the loading operation is carried out incorrectly and off-center, the conditions for the deviation of the conveyor belt are provided, and the weight of the materials and the impact caused by them during loading can affect the amount of deviation.
Conveyor deflection due to improper splice
Improper splicing of the conveyor belt is another important factor that can create conditions for the conveyor belt to deviate. In general, the conveyor belt should be smooth and uniform, and there should be no signs of protrusions or depressions in its structure. Accordingly, the splicing process of these belts must be done with high precision and detail in order to obtain a smooth and uniform surface of the belt. The smoothness of the belt surface and the misalignment of its different parts can be associated with the deviation of the conveyor belt.

Improper conditions of the conveyor belt
Among the other periodic reasons that cause the conveyor belt to deviate, we can mention the inappropriate conditions of the conveyor belt, which means that the belt used in the design of the conveyor belt does not have a healthy structure. The presence of any wear, cracking or stretching in the conveyor belt can have an adverse effect on the performance of these components and cause them to deviate. The structural problems of the belt can be caused by its inappropriate design in the factory or due to the improper maintenance of these components, which must be repaired or replaced in order to prevent the deviation of the conveyor belt.
The reasons for the permanent deviation of the conveyor belt
Among the other reasons that cause conveyor belt deviation and are included in the category of permanent reasons for conveyor belt deviation, we can mention improper adjustment of rollers, horizontal and vertical rotation of rollers, improper adjustment of the money axis and improper adjustment of straps, which are mentioned below. We will introduce each of them.
Improper adjustment of rollers and its effect on conveyor belt deflection
One of the permanent causes of conveyor belt deviation is the improper adjustment of the rollers, which have a great impact on the optimal performance of the conveyor belt during transportation. If the rollers used in the design of the conveyor belt are not adjusted correctly and do not have a level surface, this issue can have an adverse effect on the performance of the belt and cause it to deviate.

Horizontal and vertical rotation of rollers
The horizontal and vertical rotation of the rollers is another reason that causes the conveyor belt to deviate, so it is necessary to pay enough attention to this issue. The horizontal rotation of the rollers used in the design of the conveyor belt causes the belt to be pushed to one side, and as a result, the conditions for its deviation are provided. Although this rotation may be required in some situations, such as curved transmission systems, but in general, this problem can be associated with the wear of the belt edges and ultimately its deviation.
The next thing is the vertical rotation of these rollers, which has caused the alignment of these components to collide in the design of the conveyor belt, which can also have a negative effect on their performance. The asymmetry of the rollers with respect to the belt movement axis and their angle not being the same on both sides of the belt can provide the conditions for the conveyor belt to deviate.
Improper adjustment of the monetary axis
Improper adjustment of the monetary axis is another factor that can affect the performance of the conveyor belt and even cause it to deviate. These pulleys should be placed perpendicular to the direction of the conveyor belt movement and adjusted correctly, and any carelessness in this regard can lead to the conveyor belt deviation.
Improper adjustment of straps and its effect on conveyor belt deviation
Among the other reasons for the deviation of the conveyor belt, we can mention the improper adjustment of the straps, which is one of the permanent reasons for the deviation of the conveyor belt. Improper installation and adjustment of the two sides of the straps in this equipment causes more force to be applied to the belt from one side than the other side, and the same issue can be associated with more tension and friction at that edge and eventually the belt deviation.

Necessary inspections to detect deviation and fix it
If you see a deviation of the conveyor belt, it is necessary to carry out a series of inspections to determine its cause, which we will examine in this section. First, it is necessary to check the longitudinal central line of the conveyor belt and the lateral central line of the detector in terms of any inconsistency, and if the amount of this inconsistency was higher than 3 mm, the whole assembly should be adjusted through long installation holes on both sides.
The second thing is to check the state of the bearing seat plate, install the head and tail frame of the device and the amount of their deviation, and if this deviation is higher than one millimeter, these components should be adjusted in one plane. The next thing is to check the position of the material during movement on the belt, because the lack of correct and balanced loading of the material on the belt can be associated with damage to this part of the conveyor belt and its deviation. In this way, when the material is out of balance and concentrated on the right side of the belt, this part of the conveyor belt tilts to the left. Of course, in such a situation, using a baffle can help a lot to place the material on the belt and change its direction and position.
How to fix the deviation of the conveyor belt
In this section, we will discuss a series of practical methods to fix the deviation of the conveyor belt, which can be a good guide for people to fix the deviation of the conveyor belt. If the driving and moving drum axis used in the conveyor belt is not perpendicular to the center line of this device, the belt will be tight or loose, which can also be associated with its deviation. To solve this problem, if the deviation of the conveyor belt is to the left side of the drum, it is enough to move the left bearing seat forward so that the belt deviates to the right side, and the same method will also be applicable to the opposite side of the drum.
The next issue is the difference in the diameter of the outer surface of the drum, which may be due to the adhesion of the material or an error in the design. To solve this problem, the dirt on the surface of the drum must first be removed and the desired part replaced with a new and standard part. . The next issue in this field is the error and discrepancy between the parallel line of the conveyor belt and the installation position of the bearing roller assembly, which leads to the deviation of the conveyor belt. To solve this problem, the position of the roller and bearing assembly must be examined and their position should be changed to a new one according to the direction of the deviation. Of course, this work should be done by experts and with high precision so that the resulting deviation is completely fixed and other parts of the device are not damaged.

Ways to prevent conveyor belt deviation
In this section, we are going to address a series of effective solutions to prevent the deviation of the conveyor belt, which can largely prevent such problems in conveyor belts. The first solution is to introduce loads in a balanced and smooth manner on the surface of the conveyor belt, which has a great effect on maintaining the optimal performance of this equipment. The next solution is regular and continuous inspection of various parts of the conveyor, especially the belt part of this equipment, so that if any problem is observed, it can be fixed as soon as possible. Finally, the process of installing and aligning the conveyor belt should be done by experts and experienced people in this field in order to avoid such problems.
