The side of the support seat 14 away from the guide frame 15 is fixedly installed with a second driving motor 21 for driving the rotating rod 16. A through hole 17 is opened on one side of the rotating rod 16. The side of the support seat 14 is slidably connected to a moving rod 18. One side of the moving rod 18 is fixedly connected to a sliding rod 19 that is compatible with the through hole 17 and the guide frame 15. A suction cup 20 is fixedly installed at one end of the moving rod 18. The cross-section of the moving rod 18 is T-shaped. One side of the support seat 14 is rotatably connected to a limit frame 22 that is compatible with the sliding rod 19.

[0034] Specific implementation method of this embodiment: when the cardboard is pushed out by the push-out block 23, more than half of the area of ​​the cardboard is located in the guide frame 11, so one end of the cardboard tilts downward, and then the cardboard falls into the guide frame 11, and the bottom of the guide frame 11 is adapted to the thickness of a piece of cardboard, and under the action of the arc-shaped blocking bar 12, the cardboard is vertically located in the guide frame 11, and the cardboard is blocked by the blocking bar 12, and the second drive motor 21 is started, and the output end of the second drive motor 21 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the sliding rod 19 inserted in the through hole 17 to slide along the guide frame 15, and then drives the moving rod 18 to move, and the moving rod 18 is limited by the limiting frame 22, and the two ends of the arc-shaped guide frame 15 are straight, thereby driving the moving rod 18 from the vertical The movement is horizontal, and after the moving rod 18 is horizontal, it will move toward the vertical cardboard, and absorb the cardboard through the suction cup 20 connected to the external air pump. After the suction cup 20 absorbs the cardboard, the second drive motor 21 is started in the reverse direction. The second drive motor 21 drives the horizontal moving rod 18 to move away from the guide frame 11. Since the cardboard is deformable, the cardboard is pulled out of the guide frame 11, and the horizontal moving rod 18 is guided to be vertical due to the guidance of the guide frame 15, and the cardboard is placed on the conveyor belt 1. At this time, the suction cup 20 stops absorbing the cardboard, and the cardboard is located on the conveyor belt 1 and fed through the conveyor belt 1. The cardboard is positioned and placed through the moving rod 18, and the position of the cardboard on the conveyor belt 1 is limited, which is convenient for subsequent processing of the cardboard.

[0035] Among them, the second drive motor 21 mentioned above can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The second drive motor 21 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0038] Specific implementation method of this embodiment: the auxiliary wheel 25 is elastic. When the rotating transmission belt 7 drives the push-out block 23 to move to the position of the guide bar 26, the guide bar 26 squeezes the auxiliary wheel 25. The distance between the guide bar 26 and the carrying plate 3 is not greater than the thickness of a cardboard. The auxiliary wheel 25 pushes the upper cardboard upward to reduce the friction between the upper cardboard and the cardboard to be pushed out, thereby facilitating the pushing out of the bottom cardboard. When the cardboard in the limiting frame 9 is completely fed, the cardboard stack is placed in the limiting frame 9 by a forklift or other transport tools. The bracket for supporting the cardboard stack is located in the extraction slot 27, thereby facilitating the extraction of the bracket for supporting the cardboard stack.
