[0024] like Figures 1 to 4As shown, a double-knife die-cutting device for a cigarette package box proposed by the utility model comprises a bottom plate 1, a group of blades 2 symmetrical about the central axis of the bottom plate 1 are slidably arranged on the top surface of the bottom plate 1, a plurality of limiting grooves 3 for sliding of a group of blades 2 are opened on the top surface of the bottom plate 1, a slider 4 slidably arranged in the limiting groove 3 is clamped at the bottom of the blade 2, a tooth groove 5 is opened on the front side of the slider 4, a gear driving mechanism 6 meshing with the tooth groove 5 for driving the slider 4 to slide is rotatably arranged on one side of the limiting groove 3, at least one group of positioning screws 7 symmetrical about the blade 2 for fixing the slider 4 is fixedly arranged at both ends of the blade 2, and a scale groove 8 located at both ends of the blade 2 is opened on the top surface of the bottom plate 1; When in use, the utility model opens a limiting groove 3 on the top surface of the bottom plate 1, a slider 4 is arranged in the limiting groove 3, and a tooth groove 5 is opened on the side of the slider 4, and then a gear driving mechanism 6 is meshed and connected with the tooth groove 5 to drive the slider 4 to slide in the limiting groove 3, and the positioning screw 7 can fix the position of the slider 4 after movement. At the same time, the arc-shaped groove 9 opened on the slider 4 is clamped with the blade 2, so that the blade 2 can slide in the limiting groove 3, and the scale groove 8 can make the blade 2 slide a distance more accurately during the sliding process. When in use, the cutting position of the blade 2 can be adjusted to improve the paper cutting efficiency.

[0025] like Figure 3 As shown, the slider 4 is provided with an arc-shaped slot 9 for engaging the blade 2, and the arc-shaped slot 9 gradually narrows from top to bottom. When in use, since the slot 9 is an arc-shaped slot surface, the blade 2 can be smoothly docked in the arc-shaped slot 9, and the bottom of the arc-shaped slot 9 will squeeze the blade 2, thereby achieving a fixing effect on the blade 2.

[0026] like Figure 4 As shown, the gear driving mechanism 6 includes a large gear 10 and a small gear 11. The large gear 10 is rotatably set on one side of the limiting groove 3 and meshed with the tooth groove 5, and the small gear 11 is rotatably set on one side of the limiting groove 3 and meshed with the large gear 10. When in use, the small gear 11 is meshed with the large gear 10 to drive the large gear 10 to rotate, and then the large gear 10 is meshed with the tooth groove 5 to drive the tooth groove 5 to slide on the large gear 10, thereby achieving the effect of driving the slider 4 to slide.

[0027] like Figure 4 As shown, a rotating shaft 12 on one side of the pinion 11 passes through the top surface of the base plate 1, and a square groove 13 is provided on the top surface of the rotating shaft 12 for driving the pinion 11 to rotate. When in use, a square-mouth screwdriver can be used to drive the rotating shaft 12 to rotate by fitting with the square groove 13, thereby achieving the effect of controlling the rotation of the pinion 11.

[0028] like Figure 2As shown, the bottom plate 1 is composed of four layers, the top and bottom panels are made of steel plates, and the middle two panels are made of PVC. When in use, the steel plate material has the advantages of high hardness, good wear resistance, and long service life, and can meet the high-strength and high-precision production requirements, while the PVC material has a lower density and strong plasticity, but a lower cost of use. The combination of the two can reduce the manufacturing cost of the knife plate and improve production efficiency.

[0029] The working principle of the double-knife die-cutting device for cigarette packaging boxes based on the embodiment is: when the utility model is in use, the gear driving mechanism 6 is first meshed and connected with the tooth groove 5 provided on the slider 4, so as to drive the slider 4 to slide in the limit groove 3, and the sliding distance of the blade 2 is accurately controlled according to the scale groove 8, and then the position of the sliding slider 4 is fixed by the positioning screw 7, so as to fix the cutting position of the blade 2, so as to achieve the effect of being able to adjust the position of the cutting blade 2 during work, thereby achieving the effect of accurate cutting size and improving cutting work efficiency.

[0030] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
