Rollers are important components of belt conveyors, with a wide variety and large quantity, which can support the weight of the conveyor belt and materials. It accounts for 35% of the total cost of a belt conveyor and generates over 70% of the resistance, making the quality of the idler particularly important.
The function of the idler is to support the weight of the conveyor belt and materials. The operation of the roller must be flexible and reliable. Reducing the friction between the conveyor belt and the idler roller plays a crucial role in the lifespan of the conveyor belt, which accounts for over 25% of the total cost of the conveyor. Although the idler roller is a small component in a belt conveyor and its structure is not complex, manufacturing high-quality idlers is not an easy task.
Rollers play a crucial role in logistics systems. It mainly includes the following aspects:
1.Supporting function: The roller can provide stable support for the material, avoiding it from being squeezed or damaged during transportation;
2.Guiding function: The roller can smoothly transport materials from one place to another, avoiding material deviation
3.Reduce friction: The design of the roller can reduce the friction of materials during transportation, making it easier to transport materials;
4.Improve efficiency: By using rollers, the transportation efficiency of the logistics system can be improved, production efficiency can be enhanced, and production costs can be reduced.
Rollers are divided into rubber rollers, ceramic rollers, nylon rollers, and insulation rollers according to their materials. There are mainly groove shaped roller sets, various parallel roller sets, various self-aligning roller sets, and various buffering roller sets.
(1) Groove shaped rollers include ordinary rollers, forward leaning rollers, quick change bearing rollers, hanging rollers, triple chain rollers, reversible rollers, variable groove angle rollers, transition rollers, V-shaped rollers, etc;
(2) Parallel rollers include ordinary rollers, comb rollers, forward leaning rollers, steel rubber rollers, spiral rollers, etc;
(3) There are universal type, friction reversible type, strong type, cone type, spiral type, and combination type of self-aligning rollers.
