Description

Technical Field

[0001] The utility model belongs to the technical field of rubber rollers, in particular to a lightweight inner-supported rubber roller. Background Art

[0002] The structure of the rubber roller is mainly composed of a core shaft, a roller (with a rubber layer on the outer surface) and end plates at both ends, wherein both ends of the core shaft pass through the end plates to form shaft ends. Since there is a core shaft in the roller and there is no connection between the core shaft and the roller, the existence of the core shaft will cause a weight ratio. The longer the rubber roller is, the more obvious the weight ratio is, and the degree of lightweight is insufficient.

[0003] At the same time, there is no support in the middle of the rubber roller. The farther away from the end plate, the more likely it is to have insufficient strength, which affects the stability and use effect of the rubber roller. If an internal support is linearly set on the core shaft of the existing rubber roller, the overall strength of the rubber roller can be improved. However, the weight is too large, which is not easy to transport and will cause excess load on the equipment. Also, in the production process, the roller needs to be concentrically positioned with the internal support at every section, which is not conducive to assembly and processing and has low efficiency.
