Conveyor Belt Joint Technology and Connection Methods

In the conveyor system, the conveyor belt is a key component for transporting materials, and its continuity and stability are crucial to the operating efficiency of the entire system. Therefore, the selection and application of conveyor belt joint technology and connection methods have become an important part of conveyor design and maintenance. This article will discuss the joint technology and connection methods of conveyor belts in depth.

1. The importance of conveyor belt joint technology

In the conveyor system, the belt often needs to run continuously for a long time and bear the weight of the material, friction, tension and other forces. Therefore, the belt joint is often the part of the entire belt that is most prone to problems. A high-quality joint technology can ensure that the belt has sufficient strength and stability at the joint, reduce the occurrence of faults such as breakage and cracking, and thus ensure the stable operation of the entire system.

2. Common conveyor belt joint technology

Mechanical joint

Mechanical joint is one of the most common joint methods in conveyor belts. It uses special steel buckles or clamps to connect the two ends of the belt together. This joint method has the advantages of simple structure, easy installation and low cost. However, mechanical joints have certain requirements for the material and thickness of the belt, and the strength at the joint is relatively low, which is easy to break when subjected to large impact force.

Cold bonding joint

Cold bonding joint uses a special adhesive to bond the two ends of the belt together. This joint method does not require heating or pressurization, is easy to operate, and has high strength at the joint, which is suitable for belts of various materials. However, cold bonding joints require the use of specific adhesives and are operated in strict accordance with the operating procedures, otherwise it is easy to affect the quality of the joint.

Hot vulcanized joint

Hot vulcanized joint is one of the most advanced joint methods in conveyor belts. It uses a high temperature and high pressure environment to fuse the two ends of the belt with the vulcanized film to form a whole. This joint method has the advantages of high joint strength, good stability and long service life. However, hot vulcanized joints require professional equipment and operating skills, and the cost is high.

3. Application cases of joint technology and connection methods

In practical applications, different joint technologies and connection methods have their own advantages and scope of application. For example, in the conveying system of heavy materials such as coal and ore, due to the heavy weight and strong impact of the materials, hot vulcanization joint technology is required to ensure the strength and stability of the joint. In some occasions where the sealing and wear resistance are not required, such as the conveying system of materials such as grain and fertilizer, lap joints or mechanical joints can be used to reduce costs.

4. Conclusion

The joint technology and connection method of the conveyor belt are the key links to ensure the stable operation of the entire system. When selecting and applying joint technology and connection methods, it is necessary to comprehensively consider various factors such as the material, thickness, length, working environment, and transported materials of the belt. By selecting the appropriate joint technology and connection method, it can be ensured that the belt has sufficient strength and stability at the joint, reduce the occurrence of failures, and improve the operating efficiency of the entire system.
