[0045] The second driven wheel 323 and the screw assembly 325 are both provided in two groups, so that the movement of the baffle 31 is more stable and reliable.

[0046] A first sensor 33 is provided on the baffle 31. When the sensor 33 senses that there is cardboard on the conveyor belt 31, the conveyor belt is instructed to transport forward. When the sensor 33 senses that there is no cardboard on the conveyor belt 31, the staff is reminded to add cardboard in time through an alarm or other means.

[0047] The separation mechanism 4 includes a belt assembly 42 and a lifting mechanism 43. The belt assembly 42 includes a driving assembly 421, a first belt 422, and second belts 423 located on both sides of the first belt 422. The lifting mechanism 43 is used to lift the cardboard on the first belt 422 upward. The driving assembly 421 drives the first belt 422 and the second belt 423 to rotate, thereby conveying the cardboard.

[0049] The second rotating shaft 4216 is located between the first rotating shaft 4215 and the third rotating shaft 4217, so that the length of the first belt 422 is greater than the length of the second belt 423. A part of the first belt 422 and the second belt 423 together form the first cardboard transport station, and another part of the first belt 422 and the lifting mechanism 43 together form the second transport station (also the lifting station). The first transport station is used to transport the cardboard from the pre-loaded paper platform to the second transport station. The lifting mechanism 43 is located on both sides of the first belt 422, so that the cardboard on the first belt 422 can be lifted upward. After lifting, the position corresponding to the first belt 422 forms an empty space, which is convenient for the fork in the material taking mechanism to extend and fork the cardboard. The present invention cleverly sets the transmission belt into two groups, which can not only play the role of conveying cardboard, but also reserve a station for the lifting mechanism 43, saving space while reserving space for the fork when lifting.

[0050] The lifting mechanism 43 includes a top plate 431, a lifting cylinder 432 and a guide assembly 433, wherein the top plate 431 is connected to the guide assembly 433, and the lifting cylinder 432 is located below the top plate 431. The top plate 431 is lifted upward by the lifting cylinder 432, and the guide assembly 433 can play a guiding role, so that the top plate 431 can be smoothly raised or lowered.

[0051] There are two top plates 431, and the two top plates 431 are located on both sides of the first belt 422. The two top plates 431 can steadily hold up the cardboard. After the cardboard is lifted up, the space between the two top plates 431 can be used for the fork to extend into. A lifting cylinder 432 is arranged under each top plate 431.

[0052] The guide assembly 433 includes a guide column 4331 and a connecting plate 4332. One end of the guide column 4331 is connected to the top plate 431, and the other end of the guide column 4331 is connected to the connecting plate 4332.

[0054] Two flushing blocks 45 are provided at the discharge end of the separation mechanism. The flushing blocks 45 are detachably provided on the frame 1 through the connecting transfer block 46. The frame 1 is provided with a plurality of connecting holes 11. The transfer block 46 is provided with through holes. Fasteners pass through the through holes and the connecting holes 11 to fix the flushing blocks 45. At the same time, by aligning the through holes with different connecting holes 11, the distance between the two flushing blocks 5 can be adjusted, so as to be suitable for the flushing operation of cardboards of different widths. The flushing blocks 45 can perform flushing operations on the cardboards located at the second transport station to prevent the stack of cardboards thereon from being misplaced or uneven, which is convenient for subsequent material removal operations.

[0055] A second sensor 47 is provided at one side of the discharging end of the separation mechanism. When it senses that a cardboard has arrived at the second transport station, the driving structure 4211 is instructed to stop and wait until the picking mechanism 5 comes to pick up the material.

The guide rail 410 and the second screw rod 49 are both set on the mounting plate 411. The second screw rod 49 is also connected to the second driving mechanism 412. The second driving mechanism 412 drives the second screw rod 49 to rotate, thereby driving the movement of the entire separation mechanism, so that the position of the entire separation mechanism can be moved, so that its relative position with the pre-loaded paper platform can be adjusted to be suitable for paper of different widths.

[0057] The material taking mechanism 5 comprises a three-axis moving mechanism 52, a first fork 53 and a second fork 53' which are arranged on the three-axis moving mechanism 52 and whose distance is adjustable.
