In the transportation of materials, especially heavy industries such as mining, buffer rollers are needed, and the cushioning effect is obviously that of the buffer bed. Engineers have invented a buffer bed in order to reduce energy consumption and improve the efficiency of material transportation. There are many types of buffer beds in the first place, With aluminum alloy connection, the length can be adjusted with the width of the conveyor belt. Due to the weak performance of the aluminum alloy itself in the practice process, there often occur movement phenomena and potential safety problems, and gradually the connection structure is replaced by the steel structure.
According to decades of development, the length has basically been fixed at 1220,1500 two specifications, these two lengths to more scientific way to meet the material drop, the structure has also been gradually established, and the buffer bed style and structure and use Material mainly by the actual material cushioning impact and belt rack to decide, different conditions and conditions of use not only the same design.
Compared with the buffer bed, the buffer roller itself will produce the phenomenon of uneven force. There is a gap between the longitudinal arrangement of the buffer roller. Even if the gap is smashed with sharp materials, the conveyor belt may even be damaged. In addition the buffer roller itself will be smashed material. In addition there will be residual material between the buffer roller gap, resulting in waste, and some even pollute the environment. The development of the buffer bed effectively prevents the scattering of materials and the damage of the conveyor belt. Due to the large area of ??the buffer bed, the contact between the belt surface and the surface is guaranteed and the force is evenly distributed. Therefore, the longitudinal tear of the belt caused by the breaking and falling of the roller is effectively prevented and the belt is sharply reduced or sharpened Probability of longitudinal tear after material penetration.
When subjected to impact, the buffer bed plays a good buffering role primarily through its own physical resilience. The buffer bed is made up of multiple buffer strips and steel structures. The buffer strip is actually a kind of special rubber strip, which must ensure a certain elasticity so as to play the role of buffer material. The general buffer of Shore hardness of about 55 degrees, the rubber must also have a certain degree of corrosion resistance (if the underground use of rubber must be treated flame retardant rubber), and have a certain tear strength, tensile strength, elongation at break Length, rubber and metal bonding strength is also the assessment of the standard.
Impact bed for conveyor belt material loading and blanking point of protection, with impact, anti-smashing, flame retardant anti-corrosion characteristics, buffer bed and the guide groove seal the perfect combination of a very good dust-proof effect is The best tool to replace the buffer roller.
Impact bed advantages:
1. Bump and conveyor belt surface contact effectively prevent damage to the conveyor belt.
2. Belt in the mouth by the force evenly, greatly reducing the daily repair and maintenance costs.
3. Effectively eliminate due to uneven conveyor belt caused by the material splash and scattered leakage.
4. The smooth surface of ultra-high-density polyethylene minimizes the friction during conveyor operation.
5. The curved surface of the polyethylene layer design, to ensure smooth and smooth conveyor belt operation.
6. Ultra-elastic special rubber layer to maximize the impact of material absorption
7. Buffer between the various parts of the thermal curing process is connected, compact and solid.
8. The design of the underlying steel structure makes disassembly quick and easy.
