Abstract
The invention belongs to the technical field of rollers, and discloses a composite material roller and a preparation method thereof. The composite material roller is mainly characterized at the technical aspect by comprising a core shaft with bearings, and a composite material layer is arranged on an outer side of the core shaft, so that under the condition that the diameter of the roller is not lengthened, the composite material layer on the outer side of the core shaft can be very thick; when the diameter of the roller becomes smaller and smaller slowly due to the friction of the roller during use, the performance of the roller cannot be impacted, the wear resisting property is high, and the service life is greatly prolonged. The composite material roller is further improved in such a manner that fin strips are arranged on the periphery of the composite material layer; the cross sections of the fin strips take the shapes of trapezoids or similar trapezoids of which the top ends are arc surfaces. Therefore, the material is saved, the cost of the roller is reduced, the mass and the rotational power of the roller can be reduced, energy waste is reduced effectively, the friction force between the roller and a conveying belt can be enlarged, and slipping between the roller and the conveying belt is avoided.
