Description

Technical Field

[0001] The utility model relates to the technical field of roller conveyor protection, in particular to a protection device for a roller conveyor. Background Art

[0002] Roller conveyors are suitable for conveying items with a flat bottom. They are mainly composed of transmission rollers, frames, brackets, drive parts, etc. They have the characteristics of large conveying capacity, fast speed, light operation, and can realize the co-linear diversion conveying of multiple varieties.

[0003] There is a gap between the belt and the frame of the roller conveyor. If the transported items are too small, they may be accidentally stuck between the belt and the block, causing the roller to rotate obstructed and affecting the normal operation of the device. As the roller conveyor is used for a longer time, some rollers will have slightly concave surfaces. Although this does not affect the overall transportation, during the conveying process, the concave rollers may cause the material to deviate from the middle position and move to the side, or even slip off the conveyor belt, causing certain damage to the goods.

[0004] Therefore, it is particularly important to design a protective device for roller conveyors to change the above technical defects and improve overall practicality. Utility Model Content
