DETAILED DESCRIPTION

[0027] like Figures 1 to 5 As shown, the aluminum paper cutting device for producing side-opening cigarettes of the present invention includes: a first aluminum paper feeding roller 1, a first paper guide roller 2, a second paper guide roller 3, a third paper guide roller 4, a fourth paper guide roller 5, a first pair of tensioning rollers 6, a fifth paper guide roller 8, a sixth paper guide roller 9, a second aluminum paper feeding roller 10, a second pair of tensioning rollers 11, a circular cutter assembly and a cross-cutting knife assembly. Each piece of aluminum paper 29 is drawn out from the first aluminum paper feeding roller 1 or the second aluminum paper feeding roller 10, passes through the first paper guide roller 2, the second paper guide roller 3, the third paper guide roller 4, the fourth paper guide roller 5, the first pair of tensioning rollers 6, the fifth paper guide roller 8 and the sixth paper guide roller 9 in sequence, and enters the second pair of tensioning rollers 11. The second aluminum paper feeding roller 10 and the first aluminum paper feeding roller 1 are standby for each other. The aluminum paper 29 passes through the circular cutter assembly to cut a longitudinal knife mark 7, and then passes through the cross-cutting knife assembly to cut the aluminum paper 29 and cut a transverse knife mark 12.

[0028] The cross-cutting knife assembly includes: a first cross-cutting knife shaft 19, a first long cutter 22, a second cross-cutting knife shaft 23, a second long cutter 25, a first short cutter 26 and a second short cutter 27. The first cross-cutting knife shaft 19 and the second cross-cutting knife shaft 23 are respectively installed on both sides of the aluminum paper 29. A first cross-cutting knife shaft groove 20 is opened on the first cross-cutting knife shaft 19. The first long cutter 22 is fixed to the first cross-cutting knife shaft 19 in the first cross-cutting knife shaft groove 20 by a screw 21. The tip of the first long cutter 22 is aligned with the aluminum paper 29 passing through the cross-cutting knife. A second cross-cutting knife shaft 24 is opened on the second cross-cutting knife shaft 23. The second long cutter 25 is fixed to the second cross-cutting knife shaft 23 in the second cross-cutting knife shaft groove 24 by a screw 21. The tip of the second long cutter 25 is aligned with the aluminum paper 29 passing through the cross-cutting knife. The first long cutter 22 cooperates with the second long cutter 25 to cut the aluminum paper To cut the aluminum paper 29, a second horizontal blade shaft flat groove 28 is formed on the second horizontal blade shaft 23. The bottom surface of the second horizontal blade shaft flat groove 28 is perpendicular to the cutting surface of the second long blade 25. A first short blade 26 and a second short blade 27 are fixed to the symmetrical ends of this cutting surface via screws 21. The line connecting the first short blade 26 and the second short blade 27 is perpendicular to the second long blade 25. The length of the first short blade 26 and the second short blade 27 is the same as that of the second long blade 25. When the second horizontal blade shaft 23 rotates, their blade tips are aligned with the aluminum paper 29 passing through the horizontal blade. The thickness of the first short blade 26 and the second short blade 27 is 1 / 3 of the thickness of the second long blade 25. The first short blade 26 and the second short blade 27 cooperate with the first long blade 22 to cut two horizontal cuts 12 on the aluminum paper 29. The rotation speed of the first horizontal blade shaft 19 is twice that of the second horizontal blade shaft 23. The width of the first short cutter 26 and the second short cutter 27 is equal to the width of the transverse cut 12. The width of the first long cutter 22 and the second long cutter 25 is greater than or equal to the width of the aluminum paper 29.

[0029] The circular cutter assembly includes a first circular cutter roller 13, a blade 14, a first circular cutter shaft 15, a second circular cutter shaft 16, and a second circular cutter roller 17. The first circular cutter shaft 15 and the second circular cutter shaft 16 are mounted on either side of the aluminum paper 29. The first circular cutter roller 13 and the second circular cutter roller 17 are mounted on the first circular cutter shaft 15 and the second circular cutter shaft 16, respectively. The blade 14 is mounted on the first circular cutter roller 13 and occupies 1 / 2 of the circumference of the first circular cutter roller 13. The second circular cutter roller 17 corresponding to the blade 14 has an annular groove 18. The aluminum paper 29 passes through the blade 14 and the groove 18, and a longitudinal cut 7 is cut into the aluminum paper 29. The distance between the side end of the blade 14 and the side end of the first long cutter 21 is the width of the transverse cut 12. The rotation speed of the first circular cutter shaft 13 is the same as that of the second circular cutter shaft 17. The circumference of the blade 14 is equal to the length of the longitudinal cut 7.

[0030] The aluminum paper cutting device used in the production of side-opening cigarettes in this utility model is different from the traditional aluminum paper cutting method in the GDX2 packaging machine. First, the circular cutter (slitting cutter) is set in the same position, and the cutter phase is changed so that it starts cutting from 3 / 4 of the length of the previous paper to 1 / 4 of the length of the second paper. Figure 11 As shown in the figure, since the size of a single sheet of aluminum paper is the same, the fixed cutter and the adjustable long cutter are not changed. The adjustable cutter shaft flattens the vertical plane of the original short cutter and opens 3 threaded holes on each side for fixing the adjustable short cutter. Figure 6 As shown, the two adjustable short cutters are 180 degrees apart, completing two transverse cuts of the pull tab at 1 / 4 and 3 / 4 of the length of the aluminum foil respectively, forming a side-pull pull tab incision. By using this cutter device, the problem of side-opening aluminum foil cutting is effectively solved.

[0031] The utility model is improved on the basis of the existing cutter assembly. The position of the circular cutter assembly remains unchanged, the phase of the circular cutter is changed, the original short cutter is cancelled, and two short cutters are added at the position of the vertically adjustable long cutter to complete the horizontal cutting at 1 / 4 and 3 / 4 of the aluminum paper respectively, effectively solving the problem of side-opening aluminum paper cutting.

[0032] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or replacements that are not conceived through creative work should be included in the protection scope of the present invention.
