Belt Drive Circular Conveyor

Ring belt system

The main body consists of a closed ring belt, a driving drum, a driven drum, and a tensioning device. The belt is made of flexible materials such as rubber, PU (polyurethane), PVC, or food grade silicone. Depending on the scene requirements, flat belts, patterned belts (anti slip), or belts with baffles/skirts (to prevent material from slipping) can be selected. The belt is connected at the beginning and end to form a closed loop, which surrounds the driving drum and the driven drum, and is supported by the drum to form a circular conveying path (such as a horizontal circular, elliptical, or curved ring).

Drive and transmission mechanism

The drum is actively driven to rotate by the motor, and the belt is driven to circulate through the frictional force between the drum and the belt (or the toothed structure on the inside of the belt meshes with the drum teeth). The driven drum is used to support the belt and adjust the path direction (such as the curved drum at a circular turn), while the tensioning device (such as an adjustable drum or spring mechanism) ensures that the belt always maintains appropriate tension to avoid slipping or loosening.

Guidance and support structure

Underneath the belt, there are usually rollers, pallets, or support rails to prevent the belt from sagging due to the weight of the material; At the circular turn, the belt is guided smoothly by curved guide rails or guide wheels to ensure a smooth and closed path. Some devices will also be equipped with side guide strips to prevent material deviation during turning.

Belt Drive Circular Conveyor

High smoothness of transportation

The surface of the belt is soft and the friction coefficient is moderate, making it difficult for materials to bounce or slip during transportation. It is particularly suitable for transporting fragile items (such as glass products), lightweight parts (such as electronic components), or packaged finished products (such as cardboard boxes and plastic bags), reducing the risk of material damage.

Low noise and cleanliness

The friction noise between the belt and the drum is much lower than that of chain or gear transmission, and the belt material (such as PU, silicone) is not easy to produce dust. With a smooth surface design, it can meet the requirements of clean environments such as food and medicine (some can be directly rinsed and cleaned with water).

Strong flexibility and adaptability

The material and width of the belt can be flexibly customized (such as narrow belt conveying small parts, wide belt conveying large goods), and the circular path can be designed as a horizontal loop, slight tilt (small angle lifting or lowering), or complex circular path with curved turns, suitable for different workshop layouts.

Low maintenance cost

The belt is easy to replace after wear and tear, and there is no lubrication requirement for chain transmission, reducing daily maintenance workload; The drive system has a simple structure, low failure rate, and is suitable for long-term continuous operation scenarios.

Food and pharmaceutical industry

Transporting packaged food (such as bread, snacks), drugs, or medical devices, the belt is made of food grade materials (such as silicone, PU), which can withstand cleaning and disinfection and avoid contaminating materials.

Electronics and Light Industry

Transporting circuit boards and small parts in electronic product assembly lines, the smoothness of the belt can prevent damage to precision components, and the low noise characteristics are suitable for workshop environments.

Logistics sorting and packaging

In e-commerce warehouses or express sorting centers, it is used for circular transportation of light packages, combined with scanning equipment or manual sorting, to achieve temporary storage and distribution of goods.

Cosmetics and daily necessities production

Transporting bottled cosmetics, toiletries, etc., passing through labeling, coding, packaging and other workstations in a circular path, the flexibility of the belt avoids scratching the bottle body.

Exhibition and Display Scenarios

In retail or exhibitions, circular belt conveyors are used to cyclically display products (such as samples, gift boxes), and low-noise and aesthetically pleasing belt surfaces are utilized to enhance the display effect.
