Embodiment

[0025] Please refer to Figures 1-4 , a cardboard slitting device for producing honeycomb packaging cartons shown in the figure, including a cardboard cutting table 1, on the surface of which a number of equally spaced vertical frames 3 are fixed, and an electric telescopic rod 4 is installed at the center position of the surface of the vertical frame 3 through a limit seat. The bottom of the piston rod of the electric telescopic rod 4 is fixed with a bottom plate 5 that can move up and down inside the vertical frame 3 and the cardboard cutting table 1. A through groove is formed on the surface of the bottom plate 5, and a horizontal cutting assembly with the bottom passing through the through groove is fixedly attached to the surface of the bottom plate 5. A conveying roller 2 is rotatably installed between the inner walls of the cardboard cutting table 1 for conveying the movement of the support plate, and the top of the conveying roller 2 is higher than the inner surface of the cardboard cutting table 1. A fixing assembly is installed at the bottom of the bottom plate 5 symmetrically for pressing the cardboard against the surface of the conveying roller 2 from both ends at the bottom of the bottom plate 5.

[0026] The fixing assembly can move downward together with the bottom plate 5 and can press the cardboard downward before the cutting knife 12 contacts the cardboard, thereby avoiding the displacement of the cardboard due to lack of fixation when slitting the cardboard.

[0027] Further, the fixing component includes a bottom frame 13 installed in a rectangular groove at the bottom of the bottom plate 5, and a spring 14 is arranged inside the bottom frame 13. The bottom of the spring 14 abuts against a limit slider 15 penetrating through the bottom frame 13, and a cardboard pressing strip 16 is installed at the bottom of the limit slider 15.

[0028] Under normal conditions, the bottom of the cardboard pressing strip 16 is below the bottom of the cutting knife 12 and can be in contact with the surface of the cardboard in advance.

[0029] Further, limit blocks 6 are fixed at both ends of the bottom plate 5, and a vertical groove is formed between the inner wall of the vertical frame 3 and the inner wall of the cardboard cutting table 1. The end of the limit block 6 extends into the vertical groove.

[0030] Under the action of the vertical groove and the limit block 6, the stability of the bottom plate 5 during up and down movement can be improved.

[0031] Further, the transverse cutting component includes a limit frame 7 fixedly attached to the surface of the bottom plate 5. An end motor 8 is fixed at the outer end of the limit frame 7, and a screw rod 9 is rotatably arranged between the inner walls of the limit frame 7 and is in transmission connection with the output shaft of the end motor 8. A sliding block 10 that can slide horizontally along the inner wall of the limit frame 7 is screwed on the outer periphery of the screw rod 9. A tool mounting block 11 is screwed on the top of the sliding block 10, and a cutting knife 12 is inserted at the bottom of the tool mounting block 11.

[0032] The cutting knife 12 is slidably inserted at the bottom of the tool mounting block 11, which is convenient for replacement according to the thickness of the cardboard to be slit, so as to ensure meeting the cutting requirements of the corresponding cardboard.

[0033] Further, the cross section of the limit slider 15 is T-shaped.

[0034] The top of the limit slider 15 can move up and down within the bottom frame 13.

[0035] Further, a rubber sheet is bonded to the bottom of the cardboard pressing strip 16, and anti-slip lines are formed on the bottom surface of the rubber sheet.

[0036] The anti-slip lines can increase the friction between the rubber sheet and the surface of the cardboard, thereby further preventing the cardboard from moving horizontally in the moving direction of the cutting knife 12 when the cutting knife 12 moves.

[0037] Further, a notch is formed at the bottom of the electric telescopic rod 4, and the notch is adapted to the limit frame 7.

[0038] The limit frame 7 can be conveniently installed on the surface of the bottom plate 5 through the notch.

[0039] It should be noted that the present utility model is a cardboard slitting device for producing honeycomb packaging cartons. When in use, the cardboard used for mass-producing honeycomb packaging cartons is conveyed onto the conveying roller 2 under the action of the conveyor belt of the front-end equipment. The cardboard is driven to move horizontally by the self-powered conveying roller 2. When the cardboard moves below the vertical frame 3, the electric telescopic rod 4 extends and drives the bottom plate 5 to move downward. The limit blocks 6 at both ends of the bottom plate 5 move downward along the vertical grooves. First, the rubber sheet at the bottom of the cardboard pressing strip 16 contacts the surface of the cardboard. As the electric telescopic rod 4 continues to extend, the spring 14 is compressed by the external force until the bottom of the cutting knife 12 penetrates below the cardboard. The output shaft of the end motor 8 drives the screw rod 9 to rotate, so that the sliding block 10 drives the tool mounting block 11 and the cutting knife 12 to move horizontally under the action of the screw rod 9, completing the slitting operation of the cardboard. Subsequently, the electric telescopic rod 4 contracts and resets, and the slitting work of the cardboard at the corresponding station can be completed.
