[0032] The working principle of the present invention is:

[0033] When in use, the top of the L-shaped support 1 is connected to the depalletizer robot by bolts. The depalletizer robot moves left and right to move the present invention to the position of the material that needs to be adsorbed. The robot moves down to seal the open adsorption sleeve 29 with the surface of the material that needs to be adsorbed, and then the external suction equipment is started. At this time, the air in the air storage box 22 is driven by the suction equipment to flow out of the air storage box 22 from the suction pipe 21, thereby achieving the effect of sucking the material.

[0034] During this process, the piston block 11 in the telescopic assembly 2 telescopically moves along the inside of the sleeve 9, and the slide 14 in the sliding assembly 3 slides and cooperates along the slide rail 13, thereby realizing the movement cooperation between the telescopic assembly 2 and the sliding assembly 3 to guide the telescopic assembly 2; the rotating block 15 in the rotating assembly 5 rotates and cooperates with the first connecting rod 6, thereby driving the mounting plate 7 to rotate and cooperate with the rotating assembly 5, and the third connecting rod 17 on the rotating block 15 rotates and cooperates with the T-shaped connecting piece 4, thereby realizing the rotation cooperation between the telescopic assembly 2 connected to the T-shaped connecting piece 4 and the rotating assembly 5; through the above movement cooperation, the unevenness of the material adsorption surface can be adapted.

[0035] It is worth noting that the concave guide plate 28 in the present invention can better guide the air inside the air storage box 22, and there is a certain gap between the concave guide plate 28 and the air storage box 22 to avoid the adsorption surface directly blocking the air inlet when adsorbing bagged materials, thereby preventing the problem of the force area of ​​the material adsorption surface being too small and the absorption effect being poor.
