Backless/backless conveyor belt
Keyword:
Backless/backless conveyor belt
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

FAQ
Characteristics of Polyester Conveyor Belt
High modulus, low elongation, good heat stability, impact resistance and other characteristics, suitable for medium and long distance, high-speed, high-speed conditions of conveying materials.
Body material for heat-resistant conveyor belts
The subject material of the heat-resistant conveyor belt includes a skeleton material, a covering layer and a base material.
Selection of the diameter of the conveying roller
The selection of roller diameter should consider the following factors: the average specific pressure between the conveyor belt and the roller surface, the amount of deformation of the bag and the bag, the utilization rate of the allowable strength of the conveyor belt, the frequency of bending of the conveyor belt, the installation location of the conveyor and the conditions of use.
Main material of nylon conveyor belt
The main material of the nylon conveyor belt is nylon, but it does not have enough tension, so it is necessary to add a layer of industrial polyester cloth between nylon and nylon to increase the tension when making the finished product.
The advantages of the pattern conveyor belt
The pattern conveyor belt can ensure the smooth transportation of materials, with anti-skid, impact resistance, and high temperature resistance.
