Problems solved by technology

Most of the rollers currently used are metal cylinders. Due to the humid working environment, the environment is acidic or alkaline, the rollers are easily corroded, and the wear resistance of the metal is poor, resulting in a greatly reduced service life.
[0003] In order to prolong its service life, a wear-resistant rubber layer is wrapped on the outside of the metal drum. Although this improves the wear resistance of the metal drum and prolongs its service life, the drum has the following defects: First, during use, the wear-resistant The rubber layer is easy to partially fall off, causing part of the metal roller to be exposed outside, which reduces the corrosion resistance of the roller. Second, the corrosion-resistant rubber layer is relatively thin, and long-term wear will wear off the corrosion-resistant rubber layer

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.

Description

technical field [0001] The invention belongs to the technical field of composite material rollers, and in particular relates to composite material rollers and a preparation method thereof. Background technique [0002] In the transportation of solid materials such as mines, coal mines, and chemicals, most of them are completed by conveying machinery with rollers. Most of the currently used rollers are metal cylinders. Due to the humid working environment, the environment is acidic or alkaline, the rollers are easily corroded, and the wear resistance of the metal is poor, resulting in a greatly reduced service life. [0003] In order to prolong its service life, a wear-resistant rubber layer is wrapped on the outside of the metal drum. Although this improves the wear resistance of the metal drum and prolongs its service life, the drum has the following defects: First, during use, the wear-resistant The rubber layer is easy to partially fall off and causes part of the metal c...
