Description

Technical Field

[0001] This utility model relates to the field of idler roller assembly technology, specifically to an idler roller assembly that reduces wear. Background Technology

[0002] Idler assemblies are a core component of belt conveyors, primarily used to support the conveyor belt and carry materials. Their structure, type, and performance directly affect the conveyor's operating efficiency and lifespan. Idler assemblies account for 35% of the total cost of a conveyor and bear over 70% of the operating resistance; their quality is crucial to the conveyor belt's lifespan. However, current idler assemblies still have the following shortcomings:

[0003] For example, patent document CN220844085U discloses a roller assembly. This roller assembly consists of a motor, a lead screw, a rotating seat, a threaded sleeve, a base, and a fixed frame. The motor drives the lead screw at the output end to rotate. When the lead screw rotates, it drives the threaded sleeve to move inward through the thread. At the same time, the rotating seat pushes a spring telescopic rod to unfold outward. The unfolding spring telescopic rod pushes the fixed frame upward, raising it for easier use in different situations. After being raised, the four support legs can be pulled out of the storage slot and opened outward through the rotating shaft to fit against the ground, increasing the stability of the base and preventing the fixed frame and rollers from tipping over. However, during use, wear occurs inside and on the surface of the rollers, making it unsuitable for long-term use. Utility Model Content
