194mm Rubber Coated Conveyor Drive Rollers Transportation System

transportation system steel impact conveyor idler belt conveyor rollers

The conveyor roller drives the roller tube, the bearing seat, the outer ring of the bearing, and the seal ring to rotate through the friction between the conveyor belt and the roller, and realizes the logistics transmission together with the conveyor belt.

Use and operation of conveyor roller

1. Before using the roller, carefully check the appearance for any serious bumps and damage. The rotating roller should rotate flexibly without jamming.
2. The installation distance of the rollers should be calculated based on the type of logistics and the characteristics of the conveyor, and the amount of transportation should be calculated to avoid excessive or dense installation.
3. The roller installation should be adapted to avoid friction between each other.

The characteristics of trough buffer rollers and the scope of market application:

1. The trough-shaped buffer roller has the characteristics of corrosion resistance: acid, alkali and salt are not corrosive to it.
2. The groove-shaped buffer roller has strong hardness: strong abrasion resistance.
3. Good sealing: the trough-shaped buffer roller is fully sealed, with plastic labyrinth seals at both ends, oil and grease will not leak, which can make the rolling shaft long-term; the trough-type buffer roller is in a fully sealed state to run.
4. The ceramic surface of the trough-shaped buffer roller: an oxide film is formed, the surface is smooth, and the material is not adhered to, and the friction coefficient in contact with the conveyor belt is small, which reduces the driving force of the winding.
5. The trough-shaped buffer roller has a long service life: the trough-type buffer roller is 2-5 times longer than the steel roller, and it can reduce belt wear, the belt does not run off, and the belt service life is prolonged.

Interaction between roller and conveyor belt

1. The influence of the radial runout of the roller on the belt conveyor
The national standard for the radial runout of the idler rollers in my country is 0.7 mm. Within the range of the amount of runout specified by the country, the belt conveyor can be kept running smoothly, otherwise it will cause the belt conveyor belt to resonate and jump, resulting in material throwing, polluting the environment, and the advantage of small radial runout will be under the condition of high belt speed. Obviously flashed.
2. The influence of roller sensitivity on belt conveyor belt
If the roller sensitivity is not good and the rotation resistance coefficient is high, the entire belt conveyor system will have to pay more power and consume more electricity. Sometimes the belt will tear and the motor will be burned. When it is more severe Can cause a fire. Therefore, during the operation of the belt conveyor, the sensitivity of the roller is very important. The selection of rollers with a low coefficient of rotation resistance is an important part of the design and selection of the belt conveyor.
3. The influence of axial movement on the belt conveyor
Although my country’s conveyor manufacturing skills are becoming more and more advanced, axis movement is still a subject of research. Due to my country’s current belt manufacturing skills, belt conveyor installation skills are still far away from advanced countries in the world. There will be a situation where the tape is deviated. If the amount of axial movement of the idler is large, it will cause early damage to the idler. Generally, we control the amount of axial movement within 0.5-0.7 mm.
