Description

Technical Field

[0001] The utility model relates to the technical field of pallet conveying, in particular to a pallet clamp. Background Art

[0002] On a boxboard production line, finished boxboard is typically placed on pallets for storage and transfer. Pallets are typically supplied via conveyor lines, which require multiple conveying devices, are relatively costly, take up a lot of space, have complex paths, and are slow to transfer, impacting subsequent operational efficiency. To address the challenges of existing conveyor lines for pallets, a manipulator-plus-grip structure can be used to transfer pallets, improving transfer efficiency, reducing the use of conveying devices, lowering transfer costs, and conserving workspace. Furthermore, within this structure, it is crucial to provide a gripper that can stably grip the pallet and enable pallet steering.
