Description

Technical Field

[0001] This utility model relates to the field of material handling clamps, and in particular to a clamp for handling boxes. Background Technology

[0002] Explosive materials are substances that can cause an explosion, such as explosives, detonators, and black powder. Explosive materials are packaged in boxes for easy transportation. During transportation, the boxes need to be moved by a loading and unloading device.

[0003] In the prior art, a material handling device is disclosed, which includes a support plate and multiple suction cups disposed at the bottom of the support plate. The suction cups are used to pick up and put down items. It is usually used to pick up thin and light items. For large items such as boxes, the suction cups alone can easily cause the boxes to fall off during the transfer process, affecting the transfer of the boxes. Moreover, due to the weight of the contents inside the box, the suction cups adhering to the top of the box can cause the box to open, resulting in the contents scattering out of the box. Therefore, how to achieve stable gripping of boxes is a key research direction in the industry.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content
