&Buffer beds and buffer strips originated in Germany. They were invented by German engineers in order to reduce energy consumption and improve material transportation efficiency. At first, there were many design styles of buffer beds and buffer strips. In the 1970s, the connection structure was mainly made of aluminum alloy, and the length could be continuously adjusted. However, with the needs of practical applications and underground use in mining, its connection structure was gradually replaced by steel structures. In practical applications, German engineers found that the rigidity of aluminum alloy It is not strong, and the buffer strips often move around. In serious cases, the conveyor belt may tear. The most important thing is that aluminum alloy materials are prohibited from being used underground worldwide. Any aluminum alloy connection structure used underground has potential safety issues. Therefore, at the beginning of the year, German engineers all adopted the steel structure connection method. Based on decades of development, they found that the length has basically been fixed at two specifications. These two lengths more scientifically meet the material falling method and practical application. The needs and structure were gradually determined.
The buffer strip uses an excellent high-elastic special rubber layer to fully and effectively absorb the impact force when the material falls, greatly reducing the impact of the material on the conveyor belt when the material falls, and truly improving the stress at the dropping point. And it uses a special polymer polyethylene surface to reduce the friction coefficient between the conveyor belt and the buffer strip and has good wear resistance. The use of buffer strips ensures that the surface of the conveyor belt is in contact with each other and the force is evenly applied, effectively preventing the longitudinal tearing of the belt caused by the breakage and falling off of the roller, and at the same time greatly reducing the risk of the belt being penetrated by sharp objects or sharp materials. Probability of tearing.
The buffer strip consists of three parts, the wear-resistant layer && ultra-high molecular weight polyethylene, the buffer layer && high elastic rubber, the connection structure && galvanized steel structure (also available underground), the rubber is black, the wear-resistant layer The color of ultra-high molecular weight polyethylene is adjustable, and the most commonly used colors in the market are red, green and black (flame-retardant buffer strips).
Advantages of buffer strips
The surface contact of the buffer strip conveyor belt effectively prevents damage to the conveyor belt
The conveyor belt is evenly stressed at the blanking port, which greatly reduces daily repair and maintenance costs
br/>Effectively eliminate material splashing and leakage caused by uneven stress on the conveyor belt
The smooth surface of ultra-high density polyethylene reduces the friction of the conveyor belt during operation.
The arc-shaped design on the surface of the polyethylene layer ensures the smooth operation of the conveyor belt
The ultra-high elasticity special rubber layer can absorb the impact force of the material to the maximum extent
Between the various parts of the buffer strip It is connected by hot vulcanization process, compact and strong
The design of the underlying structure makes disassembly and assembly easy and fast
