[0002] When the cigarette carton on the conveyor needs to be opened, a cutting knife is usually installed on both sides to cut the adhesive tape between the upper and lower ears in the middle of the front and rear sides of the cigarette carton, but the cutting knife is flexible due to the flexibility of the cigarette carton and the adhesive tape, which can cause cutting failure and adhesion. To this end, laser cutting is used, which can completely cut, but the cutting can also cause re-adhesion after melting, resulting in cutting failure. Using a conventional hard-mounted cutting knife for cutting can easily damage the cigarette carton, such as the opening middle seam device for slim cigarette unpacking disclosed in Chinese patent application (application number 2023117836414). The inventor found during use that the cutting knife opens the middle seam, and the cutting knife is fixed, which can cause the cutting knife to cut the internal cigarette due to inaccurate positioning of the cigarette carton during the cutting process, damaging the packaging of the cigarette.

[0005] Further, the cantilever rod is movably inserted into one end of a strip-shaped adapter and then fixed by a fastener.

[0006] Further, the guide auxiliary roller below the cutting edge of the cutting knife.

[0007] The utility model discloses an advantageous effect: compared with prior art, the utility model discloses through setting up the extension spring, can make cutting knife be in the elastic cutting effect, can reduce the possibility of damaging internal cigarette, plays effective protection function, the cutter can realize height adjustment, and then adapt to the cutting middle joint of the cigarette packaging box of different height, improve equipment application scope, reduce the cost.

[0013] The utility model will be further introduced below in combination with the specific embodiment and the drawing.

[0014] Embodiment 1: as Figures 1-5As shown, the cutting mechanism for a laser cutting machine for cigarette packaging boxes includes a cutting blade 701, which is a strip-shaped structure. The cutting blade 701 is horizontally inclined towards the discharge side, with a cutting blade 702 at the front end. Near the middle and rear, it is rotatably connected to a support base 703 along a vertical axis. The rear end is connected to a fixed support point 705 on the support base 703 via a tension spring 704. The fixed support point 705 is fixed to the support base 703 with screws. The tension spring allows the cutting blade to operate under elastic cutting action, thus providing protection. The fixed support point 705 and the rear end of the cutting blade 701 are located on the left and right sides of the vertical axis, respectively. A cantilever rod 706 is fixedly connected to the rear side of the support base 703. The cantilever rod 706 moves through one end of a strip-shaped adapter 707 and is fixed with fasteners, enabling directional adjustment of the cutting blade in the forward and backward directions. The middle of the adapter 707 is fixedly connected to the... On the slider of a vertical slider guide pair 708, the guide rail of the first vertical slider guide pair 708 is fixedly connected to the fixed plate 709, and the fixed plate 709 is fixedly connected to the groove plate 710. The groove plate 710 is installed on the horizontal linear moving mechanism installed on the upper end of the frame of the glue cutting machine. An auxiliary roller 713 is provided on the side of the groove plate 710 facing the cigarette pack box, which can play a better stabilizing role. The other end of the adapter 707 is fixedly connected to the nut of the vertical first lead screw nut pair 711. The upper end of the lead screw of the first lead screw nut pair 711 is fixedly connected to the tool lifting motor 712. The tool lifting motor 712 is fixedly connected to the fixed plate 709. The tool can realize height adjustment, thereby adapting to the cutting seam of cigarette pack boxes of different heights, improving the applicability of the equipment, reducing costs, and, together with the height adjustment of the cutting laser module, making it easier and faster to change the equipment to adapt to new product requirements.

[0015] To ensure stable cutting, a guide roller is located below the cutting edge of the cutting blade.

[0016] In use, the cutting mechanism is symmetrically installed on the horizontal linear moving mechanism on both sides of the cigarette pack conveying mechanism. By moving horizontally to a set width, it cuts the conveyed cigarette pack and makes a center slit in the tape in the middle of the cigarette pack.
