Description

Technical Field

[0001] The utility model relates to the technical field of roller conveyors, in particular to an anti-collision roller conveyor. Background Art

[0002] Roller conveyor is a kind of equipment used for material transportation. It uses the rotation of the roller to promote the movement of materials, thereby realizing automated production and logistics transportation. Due to the high degree of automation of roller conveyor, it can greatly reduce the time and cost of manual material transportation and improve production efficiency. In the process of conveying materials, roller conveyor can prevent materials from being damaged or contaminated. However, in the process of conveying heavy objects, it needs to withstand a certain amount of cargo impact. Therefore, it is necessary to set an anti-collision mechanism to reduce the damage caused by collision. For example, a Chinese patent discloses an anti-collision roller conveyor, and its application number is: CN201220195809.0. The roller conveyor is equipped with an anti-collision device, which reduces the impact force when the pallet conveyor chain conveys the goods pallet to the conveyor frame, does not cause damage to the conveyor frame and pallet, thereby reducing noise and increasing the service life of the conveyor and goods pallet. However, there is no adjustable movable elastic mechanism. When the transported goods hit the side, it will produce an angle rotation, which may cause the goods to be stuck and unable to move. In addition, when transporting fragile goods, sufficient buffering is needed to reduce the impact force to provide the most effective protection for the goods. Utility Model Content
