Description

Technical Field

[0001] The utility model belongs to the technical field of rollers, and in particular relates to a sealed and waterproof plastic roller. Background Art

[0002] Rollers are important components of belt conveyors. They support the weight of the conveyor belt and materials, and help reduce the friction between the conveyor belt and the rollers, which has an important impact on the life of the conveyor belt. There are many types of rollers and a large number of them. They account for 35% of the total cost of a belt conveyor and generate more than 70% of the resistance.

[0003] If the seals at both ends of the roller are not tight, moisture may easily penetrate into its interior. Once moisture contacts the internal metal parts, it will quickly cause corrosion and rust problems, which will not only make the roller produce unnecessary noise and vibration during operation, but will also directly weaken its rotation flexibility and significantly reduce its overall service life.

[0004] Therefore, in view of the above situation, it is urgent to develop a sealed and waterproof plastic roller to overcome the shortcomings in current practical applications. Summary of the invention
