The surface layer of the impact bed is made of UHMW-PE with small friction coefficient, and through the high elasticity rubber buffer bar fixed on the steel bracket, which can absorb the impact of materials on the conveyor belt by relying on the effective support of the conveyor belt, reduce the wear of the conveyor belt, and extend the service life of the conveyor belt. Its overall structure design is reasonable, can be used together with the feeding groove seal group plate, achieve good sealing effect, is the ideal product of the blanking opening buffer equipment.
