Buffer bed's Disadvantages
Replacing the traditional buffer idler, the buffer idler is the first choice before the blanking buffer bed is used. It has been used continuously for decades. However, the problems such as the tearing of the conveying belt, the tight sealing of the blanking port, the falling and accumulation of materials and so on have plagued the users all the time, resulting in a great waste of production capacity and an increase in labor costs. The material accumulation and conveying belt of the blanking accumulation material longitudinally tears the defects of the traditional roller support. 1. The supporting idler has poor buffering capacity and cannot well absorb the strong impact force of falling materials. It is easy to crush the supporting idler and form the danger of longitudinal tearing of the belt. 2. The support roller is easy to fall off due to frequent impact of materials, and the upright support seat of the support roller is easy to hang or tear the belt. 3. The supporting idler and the conveying belt are in line touch, and are suspended between the two rollers. It is easy for other sharp hard objects of the material ring to penetrate the belt between the two idlers and get stuck between the idler and the blanking port, resulting in longitudinal belt tearing. 4. The belt between the two rollers is easy to droop, which makes the belt between the blanking port undulate, causing the blanking port to have poor sealing performance, resulting in material scattering and environmental pollution. 5. The surface of the supporting roller is inelastic, and materials are easy to adhere to the surface during long-term operation, which may wear the belt. Serious cases may cause belt deviation. 6. The rolling bearing of the supporting roller is impacted for a long time, and the seal of the bearing is easy to fail, resulting in insensitive or non-rolling of the roller body and abrasion of the belt surface. For this reason, many engineering planning companies in the world have successively planned different material buffering equipment to improve material buffering. Finally, buffer bed created by German engineers has been recognized by customers and selected by the world through gradual improvement. The universal structure of the buffer strip is made up of three parts: ultra-high molecular weight polyethylene plate+elastic rubber+steel pole. This structure was finally determined through long-term planning and applicable adjustment. This structure is a universal structure in the world. Due to relatively backward technological skills in the domestic market, few manufacturers can produce this structure. Through the following skills analysis and practical examples, we can realize this problem well.
