DETAILED DESCRIPTION

[0018] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention. Example

[0019] like Figure 1-Figure 4 As shown, in this embodiment, a packaging box cardboard slitting device is provided, including a conveyor platform 1, on which a driving wheel 9 for pushing the cardboard to move is rotatably installed, and the driving wheel 9 is rotatably installed on the surface of the conveyor platform 1. The conveyor platform 1 is provided with a motor 15 for driving the driving wheel 9 to rotate, and multiple driving wheels 9 rotate at the same speed at the same time. The driving method is a prior art and is not an innovation of the present utility model, so the present utility model will not be elaborated in detail.

[0020] A cutting device for cutting cardboard is installed in the middle of the conveying platform 1, a positioning plate 8 is fixed in the middle of the conveying platform 1, and the cutting device is arranged above the positioning plate 8. The cutting device includes a pressing plate 4, which can compact the cardboard, and a side edge of the pressing plate 4 for pressing the cardboard is provided with a cutting blade 16 for cutting the cardboard. The cutting device includes a support platform 3 that can slide up and down, a pressing plate 4 is fixed at the bottom of the support platform 3, a slide groove is provided inside the pressing plate 4, and the cutting blade 16 is slidably installed in the slide groove, and a driving cylinder 17 for driving the cutting blade 16 to slide up and down is fixed in the support platform 3, and the slide groove is opened at the side edge of the pressing plate 4 for pressing the cardboard, and the cutting blade 16 can slide out of the slide groove, and the cutting blade 16 is hidden in the slide groove. The pressing plate 4 can press the cardboard and leave a groove mark on the cardboard, which is convenient for subsequent cardboard bending.

[0021] A rotatable support block 5 is installed at the end of the conveying platform 1. The support block 5 can convey the cardboard on the conveying platform 1 to the storage chamber 12. The support block 5 rotates around the rotating shaft 10. Two driving wheels 11 are rotatably installed on the support block 5. The cardboard can pass through the gap between the two driving wheels 11, and the two driving wheels 11 can clamp the cardboard.

[0022] A bottom box 6 for containing cardboard is installed at the bottom of the conveying platform 1, and a storage cavity 12 is provided in the bottom box 6. A suction cup 13 is slidably installed inside the storage cavity 12. The suction cup 13 can adsorb the cut cardboard. The suction cup 13 is slidably installed in the bottom box 6 through a rack. A ventilation pipe connected to the suction cup 13 is provided inside the rack. The ventilation pipe is connected to an external fan. The fan can be connected to the suction cup 13 through the ventilation pipe, so that the suction cup 13 has an adsorption function. Figure 2 The ventilation pipe is a telescopic pipe and can be extended.

[0023] When in use: pull out the cardboard on the coil 2, pass it between the pressure shaft 7 and the driving shaft, and pass it through the bottom of the cutting device. When cutting, first apply pressure to the cardboard through the pressure plate 4, and the pressure plate 4 will press marks on the cardboard. If cutting is required, the cardboard is cut by the cutting blade 16. After the cutting is completed, the cardboard continues to move driven by the driving wheel 9. When it moves to the two active wheels 11 to clamp the cardboard, the support block 5 rotates, and the cardboard will slide vertically downward into the storage chamber 12, and then the cardboard is adsorbed by the suction cup 13. The gear 14 pushes the cardboard to one end of the storage chamber 12 through the suction cup 13. Repeating the above actions can continue to cut the cardboard.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
