Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a belt conveyor with a belt limiting function. Background Art

[0002] Belt conveyor is a common material handling equipment, which transports materials from one place to another by driving a rubber conveyor belt through a rotating drive wheel. This machine has the advantages of large conveying capacity, simple structure, convenient maintenance, and standardized parts. It is widely used in mining, metallurgy, coal and other industries to transport loose materials or finished items.

[0003] Announcement No. CN 219669151 U discloses a belt conveyor with a belt limiting function. The pushing mechanism can push the limiting block to move on the surface of the rotating roller, so that the limiting block can be clamped after adjusting the width of the first belt to prevent the first belt from deviating or seriously deviating and causing breakage.

[0004] The belt conveyor with belt limiting function can push the belt by means of the limiting block arranged on the pushing mechanism, so that the belt is not easily deviated. However, after the belt has been used for a long time, the belt is prone to loosening, so that the belt can be greatly deviated. The limiting block cannot effectively limit the belt, so improvement is needed. Utility Model Content
