The carrier rollers are important parts of the belt conveyor, are various in variety and large in quantity, and can support the weight of the conveying belt and the materials. It accounts for 35% of the total cost of a belt conveyor, and generates more than 70% of resistance, so the quality of the carrier roller is particularly important. The carrier roller is used for supporting the weight of the conveying belt and the materials. The carrier roller must be flexible and reliable in operation. The friction force between the conveyor belt and the carrier roller is reduced, and the service life of the conveyor belt accounting for more than 25% of the total cost of the conveyor is played a key role.
At present, the carrier roller is mainly made of steel and plastic. The steel carrier roller is easy to corrode or age, the bearing seat is easy to rust to cause the carrier roller to resist rotation, the working effect of the whole production is affected, the steel carrier roller is not high-temperature resistant, the wear-resisting effect is poor, and the environment protection is not facilitated; the strength of the plastic carrier roller is insufficient, the impact resistance is poor, and the plastic carrier roller is easy to break; the full ceramic idler is wear-resistant, but has large weight, is fragile and is inconvenient to install; the rubber carrier roller has inflammability problem and easily causes potential safety hazard. Although a method of arranging a wear-resistant layer outside a carrier roller is adopted at present to improve the wear resistance of the carrier roller, for example, a published Chinese patent (publication number is CN 210794736U) discloses a composite carrier roller, namely, a plurality of wear-resistant layers are arranged on the outer surface of a roller body, but the wear-resistant layers are directly fixed on the carrier roller, so that the carrier roller is inconvenient to detach, and once the wear-resistant layers are damaged, even if the roller body is still available, the whole carrier roller can be replaced, thereby increasing the economic cost.
For this reason, a composite idler is needed to solve the above-mentioned problems.
