Specifically, the first servo motor 21 rotates to control the swing arm 22 to rotate until the swing arm 22 reaches the proximity switch. Then, the lifting cylinder 31 pushes down the connecting frame 32 until the multiple vacuum suction cups 4 adsorb above the cardboard at the bottom of the paper barrel. Then, the lifting cylinder 31 pulls up the connecting frame 32 and the vacuum suction cups 4 to separate from the top of the storage bin 5. The first servo motor 21 rotates to control the swing arm 22 to rotate until the vacuum suction cups 4 reach above the discharging station. Then, the lifting cylinder 31 lowers the vacuum suction cups 4, and the adsorption force of the vacuum suction cups 4 is disconnected to realize the downward placement of the cardboard at the bottom of the paper barrel. During this process, every time a cardboard at the bottom of a paper barrel is transferred out of the storage bin 5, the second servo motor 61 rotates to drive the first belt pulley 62 to rotate. The first belt pulley 62 drives the second belt pulley 63 to rotate through the belt 64. Since the inside of the second belt pulley 63 is in threaded cooperation with the screw rod 8 and the vertical position of the second belt pulley 63 does not change, the screw rod 8 rises. The rising of the screw rod 8 drives the lifting plate 7 to push up the cardboard at the bottom of the paper barrel in the storage bin 5. It can control the upward movement of only the thickness of one layer of the cardboard at the bottom of the paper barrel, or it can also be that when the lifting cylinder 31 lowers the vacuum suction cups 4 and cannot adsorb the cardboard at the bottom of the paper barrel, a larger height is lifted at one time.

[0049] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
