[0002] Waterproof non-metallic rollers are derived from industry demand, technological development, environmental protection and sustainable development needs. The increasing demand for conveying equipment in logistics, mining, construction and other industries has promoted the widespread application of waterproof non-metallic rollers. The application of non-metallic materials and the upgrading of manufacturing processes have provided strong support for the research and development of waterproof non-metallic rollers, and improved their corrosion resistance, wear resistance and other properties. At the same time, with the enhancement of global environmental awareness, waterproof non-metallic rollers, as an environmentally friendly product, meet environmental protection requirements, and their longer service life and lower maintenance costs help to reduce corporate operating costs, reduce resource waste, and comply with the concept of sustainable development.

[0003] According to the Chinese patent with the announcement number: CN204660716U, a waterproof roller is proposed, including a roller shaft and a tube skin, a bearing seat is provided between the roller shaft and the tube skin, a bearing is provided between the bearing seat and the shaft, an inner seal is provided on the outside of the bearing, an outer seal is provided on the outside of the inner seal, the outer seal and the inner seal form a labyrinth seal, a retaining ring is provided on the outside of the outer seal, a dust cover is provided on the end face of the bearing seat, a waterproof ring is installed in the dust cover, the contact surface of the waterproof ring and the roller shaft is provided with at least three layers of elastic lips, the contact surface of the waterproof ring and the outer seal is provided with at least one layer of elastic lip, a groove is provided on the side of the waterproof ring facing the outer seal, and grease is injected into the groove. The dust cover of the utility model is provided with a waterproof ring, the contact surface of the waterproof ring and the roller shaft is provided with at least 3 layers of lips, and the contact surface of the waterproof ring and the outer seal is provided with at least 1 layer of lips. The at least 4 lips increase the waterproof effect by 3-4 times, and the waterproof ring is provided with a groove, which can be injected with grease, which can ensure long-term lubrication of the bearing and improve the service life of the bearing and the roller shaft.

[0004] In the above scheme, it was found during use that the waterproof roller has a simple structure and cannot be effectively waterproof. Once moisture enters the interior of the roller, it will directly affect the lubrication and normal operation of the bearing, and will cause the friction between the bearing and the seal to increase, thereby generating greater noise. The bearing is prone to rust and corrosion in a humid environment, causing bearing damage, which in turn affects the overall performance and service life of the roller. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a waterproof non-metallic roller, which solves the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A waterproof non-metallic roller comprises: a main body, both ends of the main body are respectively provided with mounting grooves, one side of the interior of the mounting groove is provided with a mounting hole, two limit bars are fixedly installed inside the mounting groove, a support rod is fixedly installed inside the mounting hole, and a waterproof component, wherein the two waterproof components are respectively arranged at both ends of the main body for sealing and waterproofing.

[0013] Preferably, a high molecular polyethylene sleeve is fixedly mounted on the outer circular wall of the fiberglass sleeve, and an anti-slip pattern is provided on the outer circular wall of the high molecular polyethylene sleeve.

[0014] By adopting the above technical solution and setting a high-molecular polyethylene sleeve, which is a very wear-resistant material, it can significantly reduce the friction and wear between the conveyor belt and other contact surfaces, further extending the service life of the roller. At the same time, it has good impact resistance, can absorb and disperse impact energy, and protect the roller from accidental damage.
