Handling of common faults of conveyor belt (Part 2)

in the process of designing appropriate heat treatment process and adding its mechanical function, the relative height of two belt conveyors should be increased as much as possible. The form and size of the upper and lower funnels, guide grooves and other parts of the mobile bulk material conveying machinery limited by space should be carefully considered. Generally, the width of the guide groove should be about two-thirds of the belt width, which is more appropriate. In order to reduce or avoid belt deviation, a baffle can be added to block the material and change the falling direction and position of the material

6 . The adjustment of two-way running belt conveyor deviation the adjustment of two-way running belt conveyor belt deviation is relatively much more difficult than the adjustment of one-way belt conveyor deviation. In the specific adjustment, you should adjust one direction first, and then adjust the other direction. During adjustment, carefully observe the relationship between the movement direction of the belt and the deviation trend, and drive the axis of the photoelectric encoder to change one by one for adjustment. The focus should be on the adjustment of the driving drum and the reversing drum, followed by the adjustment of the idler and the adjustment of the material blanking point. At the same time, it should be noted that when vulcanizing the joint of the belt, the force on the length direction of the belt section should be uniform, and the forces on both sides should be as equal as possible when using the guide chain traction

II. Handling of belt conveyor scattering

scattering of belt conveyor is a common problem. When this number is exceeded, it will be automatically covered up and stored from 1. The reasons are also various. But the key is to strengthen daily maintenance

1. Material spreading at the transfer point. The material spreading at the transfer point is mainly at the drop hopper, guide chute, etc. For example, the belt conveyor is strict. At present, there are many heavy overloads in China's medical device segmentation industries. The rubber skirt of the guide chute of the belt conveyor is damaged. The steel plate at the guide chute is designed to be far away from the belt, and the rubber skirt is relatively long, which makes the materials rush out of the guide chute. The above situation can be solved by controlling the transportation capacity and strengthening the maintenance

2. Scattering when the concave belt is suspended. When the curvature radius of the concave section is small, the belt will be suspended. At this time, the grooving condition of the belt will change, because the belt has left the grooved idler group, and generally the groove angle will become smaller, so that some materials will be scattered. Therefore, in the design stage, a larger radius of curvature of the concave section should be used as much as possible to avoid this kind of situation. For example, on the mobile mechanical ship loader and stacker reclaimer, the concave section here is designed as a transition section without arc in order to shorten the tail car. When the belt width is selected with a small margin, it is easier to spread materials

3. Scattering when the belt deviates. The scattering when the belt deviates is because the height of the two edges of the belt changes during operation. One side is high and the other side is low, and the materials are scattered from the low side. The treatment method is to adjust the deviation of the belt
