Different types of conveyor rollers have their own characteristics in the production line. The use of conveyors reduces the risk of injury to employees and creates a safer working environment.

How does the conveyor work? From the article, we can learn more about the relevant content, select the appropriate type of conveyor drum and improve the work efficiency.

How does the conveyor roller work?

Conveyor rollers is generally composed of conveying roller, support, driving parts, frame, etc. The utility model has the advantages of simple structure, safety and reliability, convenient maintenance and application, and is suitable for conveying goods. The landing point is a flat object.

The conveyor roller can work in different ways according to the requirements of industry. For example, the gravity roller can work without external motor drive.

The transfer rollers will be connected horizontally, which with a small space between each roller so that they can rotate. Rollers made of suitable materials can be selected according to the application, such as metal materials, rubber, plastic, etc.

You can create and install rollers with corresponding diameter and length by applying load capacity. And selecting rollers with appropriate strength will ensure that they have sufficient functionality and durability for your business.

What types of conveyor rollers are there?

Gravity conveying rollers

The gravity conveying roller uses the gravity of the transported materials to provide power for the roller and realize short-distance transportation. Due to the role of neutrality, transportation needs to be carried out at a certain slope.

Gravity rollers are used to conveyor objects with sufficient weight to move without assistance. Since the roller needs gravity to move, if an object is too light, it will not move on the conveyor belt. Some examples of products where gravity rollers are well suited for transportation are medium weight food and packaged goods.

Electric roller

The electric roller is a new type of driving device which places the motor and reducer inside the roller. It mainly replaces the motor of traditional conveyor and is suitable for high-power belt conveyor.

Free rotating conveying roller

The roller with bearing can freely coordinate the rotation capacity. The roller is suitable for manufacturing conveyor belt support system and other highly adaptive fields.

Allow the roller to rotate freely to help the conveyor transfer.

It can meet different load conditions of the conveyor. High tension conveyor belt has high strength and low extensibility. Compared with other rollers, this conveyor has higher requirements for rollers.

The starting, braking and other dynamic loads of the conveyor are directly transmitted to the drum. When it comes to high tension, the concentricity of the drum and the accurate alignment between the drum and the conveyor are very important Mechanized roller conveying

Vacuum roller

In order to increase the friction between the conveyor belts, a vacuum pump or an external vacuum pump is installed on the roller to make the vacuum between the conveyor belt and the wrap angle of the roller, but the structure is relatively complex.

Vane roller

The roller is composed of many transverse blades to facilitate the cleaning of the conveyor belt, mainly to clean the conveyor.

The roller is an important part of the conveyor. The failure of the roller will also bring serious consequences to the whole conveyor system.

The following are the common forms of drum failure.

Crack: the crack mainly occurs at the welding between the connecting plate of the drum and the whole body. Large stress is generated in the welding process, and the weld shrinks with the decrease of temperature. The existence of stress concentration may lead to cracks in welding manufacturing or crack propagation in use.

Fracturing: the drum is subject to large specific pressure for a long time, which is easy to cause fracturing damage to the drum. The cracks often crack irregularly along the axial direction from the welding place of one side of the web to the welding place of the other side.

The connecting bolt of the expansion sleeve is cut or bent too much.

In order to reduce such problems among various rollers, the roller welding technology can be effectively optimized. In addition, cleaning is required before and after welding to effectively improve the weld quality. When selecting welding materials, they should match the strength of the roller.
