[0021] Specifically, Figures 1 to 9 As shown, in this embodiment, the lifting and loading module 3 includes: a conveying mechanism 31, a fixed frame 32, a cardboard clamping mechanism and a cardboard suction mechanism; the output end of the conveying mechanism 31 is connected to the fixed frame 32, the conveying mechanism 31 drives the fixed frame 32 to move, and the conveying mechanism 31 is connected to the conveyor 1 and the turnover module 4. In this embodiment, the conveying mechanism 31 needs to drive the lifting module as a whole to move in the vertical direction and the horizontal direction to achieve docking with the conveyor 1 and the turnover module 4. The conveying mechanism 31 can adopt a two-dimensional motion module, a three-dimensional motion module or a mechanical arm; the cardboard clamping mechanism and the cardboard suction mechanism are fixed on the fixed frame 32; the cardboard clamping mechanism clamps and fixes part of the cardboard 5, and the cardboard suction mechanism absorbs and fixes the remaining cardboard 5 after the cardboard clamping mechanism clamps and fixes it. Specifically, the cardboard clamping mechanism can clamp multiple cardboards 5 at a time, but due to the limitation of the clamping thickness and the requirement of clamping stability, it is impossible to clamp all the cardboards 5 on the tray 2, and there will inevitably be a few remaining cardboards 5. Therefore, for the remaining cardboards 5, the cardboard suction mechanism is required to absorb a single cardboard.

When the first linear motion module 331 drives the first clamp 336 to approach the second clamp 337, the cardboard 5 is clamped, and when the first linear motion module 331 drives the first clamp 336 to move away from the second clamp 337, the cardboard 5 is loosened.

[0023] Further, if Figures 1 to 9 As shown, in this embodiment, a plug plate or a plurality of splicing teeth 338 are provided at the bottom of the first clamping plate 336. By inserting the plug plate or the splicing teeth 338 between two adjacent layers of cardboard 5, the clamping and fixing effect can be further enhanced. Since the use of the splicing teeth 338 will inevitably damage the cardboard 5, the splicing teeth 338 are suitable for scenes where the requirements for the cardboard 5 are not high. For scenes with high requirements for the quality of the cardboard 5, a plug plate can be used, and the plug plate and the first clamping plate 336 are integrally formed.

The second L-shaped plate 345 moves to one-third of the length of the second guide rail 343 and is inserted into the larger gap between the lifted cardboard 5 and the remaining cardboard 5. The second cylinder 342 extends again, driving the shell of the second cylinder 342 and the second L-shaped plate 345 to continue to move, so that the distance between the second L-shaped plate 345 and the first L-shaped plate 344 is one-third of the length of the second guide rail 343, thereby achieving uniform support for the cardboard 5.

When the third cylinder 351 is in a retracted state, the pair of rotating plates 352 are in a horizontal state, and the third cylinder 351 is extended, which drives the rotating plate 352 to rotate 90° and be in a vertical state, so that the suction cup 354 at the bottom of the rotating plate 352 is opposite to the cardboard 5, and the cardboard 5 is sucked and fixed.

[0026] Further, if Figures 1 to 9 As shown, in this embodiment, the lifting and loading module 3 also includes: a pallet clamping mechanism, which includes: a pair of fourth cylinders 361, a pair of first rotating shafts 362, a pair of connecting rods 363 and pallet clamping claws 364; after the cardboard 5 is grabbed, this part is used to grab the pallet 2, so as to facilitate the removal of the pallet 2 from the conveyor 1; a pair of first rotating shafts 362 are rotatably arranged on the fixed frame 32, one end of the pair of first rotating shafts 362 is respectively connected to one end of the pair of connecting rods 363, and each first rotating shaft 362 is fixed with a pair of pallet clamping claws 364, when the first rotating shaft 362 rotates, the tray clamping claw 364 is driven to rotate together; a pair of fourth cylinders 361 correspond to a pair of connecting rods 363 one by one, and the two ends of the fourth cylinder 361 are respectively hingedly connected to the other end of the connecting rod 363 and the fixing frame 32; the fourth cylinder 361 is extended and retracted to drive the connecting rod 363 and the first rotating shaft 362 to rotate, thereby driving the tray clamping claw 364 to rotate, so as to achieve the closing or separation of the relative tray clamping claw 364; the tray clamping claw 364 can be L-shaped, and the tray clamping claw 364 clamps the fixed tray 2; In this embodiment, when the conveying mechanism 31 is a robotic arm or a three-dimensional motion module, the conveying mechanism 31 can drive the pallet clamp 364 and the pallet 2 to move. When the conveying mechanism 31 is a two-dimensional motion module, since the conveying direction of the cardboard 5 is different from the unloading direction of the pallet 2, and the two-dimensional motion module can only move in one direction at the same horizontal height, when a two-dimensional motion module is used, the pallet clamping mechanism is not required, and other devices are used to unload the pallet 2.

[0027] Specifically, Figures 1 to 9 As shown, in this embodiment, the turning module 4 comprises: a supporting frame 41, a plurality of conveying components, a turning mechanism, a pair of shaping cylinders 42 and a pair of shaping plates 43; The turning mechanism and a pair of shaping cylinders 42 are fixed on the support frame 41; A plurality of conveying components are fixed on the support frame 41 at intervals, and the conveying components include a first conveying belt 44 and a second conveying belt 45.

The first conveying belt 44 is connected to the lifting and loading module 3. The conveying speeds of the first conveying belt 44 and the second conveying belt 45 can be the same or different. When the conveying speeds are different, faster conveying can be achieved. The flipping mechanism is arranged between the first conveyor belt 44 and the second conveyor belt 45. The flipping mechanism clamps the paperboard 5 conveyed by the first conveyor belt 44, drives the paperboard 5 to flip 180 degrees vertically upward and place it on the second conveyor belt 45; A pair of shaping cylinders 42 are respectively fixed on both sides of the support frame 41, and the output ends of the pair of shaping cylinders 42 are connected to a pair of shaping plates 43 to drive the pair of shaping plates 43 to close or separate.
