Roller with wear-resistant surface

The surface abrasion-resistant roller comprises a shaft core, an abrasion-resistant sleeve is connected to the surface of the shaft core in a sleeved mode, connecting rods are installed on the two sides of the shaft core in a penetrating mode, limiting plates are installed on the two sides of the shaft core in a penetrating mode, and injection pipes are installed on one sides of the connecting rods in a penetrating mode. The buffer layer is fixedly arranged on the inner wall of the wear-resisting sleeve, the friction capacity of the surface of the roller can be improved through the wear-resisting sleeve, then a buffer space can be formed between the wear-resisting sleeve and the roller body through the buffer layer, and the problem that the wear-resisting sleeve is deformed and damaged when high temperature is achieved through rotating friction is avoided; and then through the silicone grease heat dissipation layer and by utilizing the characteristics of a silicone grease material, high temperature generated
