Backless conveyor belt

Backless/backless conveyor belts have no adhesive coating on the back, using canvas, nylon/EP polyester/NN/EE, etc. as the core, and paired with wear-resistant coating. It reduces friction, prevents material adhesion, is easy to clean, has good flexibilit

Details

Product Description:
Backless type is suitable for lightweight materials.
Backless conveyor belts run on steel, wood, or other low-friction surfaces (sliding beds) and are suitable for conveying with low friction.
Compared with standard conveyor belts, the difficult wear and tear between the conveyor belt and the frame is reduced, thereby minimizing conveyor belt wear and improving efficiency.

Structural Features
• Top cover/upper cover rubber: Can be produced with a flat surface or various textured embossing
• Belt core layer: Usually made of materials such as cotton canvas, nylon cloth, polyester cloth, aramid cloth, or steel wire rope core, which is the main load-bearing component.
• Cover rubber: Wrapped on the upper and lower sides of the belt core skeleton. Generally, rubber formulations with corresponding properties are selected according to the usage environment and requirements, such as oil resistance, wear resistance, cold resistance, flame resistance, heat resistance, and ozone resistance.
• Backless design: Unlike ordinary conveyor belts, the back is not coated with glue and is exposed, which can reduce adhesion and friction with the transmission components. 。

Advantages

• Reduce friction and wear: The glue-free back reduces the coefficient of friction between the rollers, drums, and other components, reducing conveyor belt wear, improving operating efficiency, and extending service life.

• Prevent material adhesion: The glue-free back is not easy to adhere to materials, avoiding problems such as spillage and accumulation of materials during conveying due to adhesion, and maintaining a clean conveying environment.

• Easy to clean and maintain: The backless design makes the back of the conveyor belt easier to clean, reducing maintenance costs and difficulty, and improving the operational stability of the equipment.

• Good flexibility: The backless design gives the conveyor belt better flexibility, allowing it to better adapt to various complex conveying lines and bending radii, reducing resistance and deformation of the conveyor belt during operation.

Application Scenarios

• Food and beverage industry: Used to convey biscuits, candies, beverage bottles, and other food and beverage products. The glue-free back avoids contamination of food and ensures food safety.
• Electronics and electrical appliances industry: Suitable for conveying electronic components, circuit boards, and other precision electronic products, preventing glue residue from damaging products.

• Pharmaceutical industry: In the production and packaging of pharmaceuticals, it can be used to convey medicines, medicine bottles, etc., meeting the strict requirements of the pharmaceutical industry for hygiene and cleanliness.

• Logistics and warehousing industry: Used for sorting, conveying, and storing goods. The glue-free back reduces adhesion between goods and the conveyor belt, improving the conveying efficiency and accuracy of goods.

• Automotive industry • Rubber industry • Woodworking/sawmill • Recycling plant • Waste treatment
