It should also be understood that the terms defined in, for example, a general dictionary should be interpreted to have meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or excessively formalized sense, unless specifically defined herein.

[0034] The technology, methods and devices known to the ordinary skilled person in the relevant field can not be discussed in detail, but should be considered as part of the specification where appropriate.

[0035] In some related technologies, the die-cutting device of the cigarette package includes an outer frame 1 and a die plate 2, the outer frame 1 is formed with an annular space, and the die plate 2 is arranged in the annular space. The middle region of the die plate 2 is a cutter area 23, and the cutter area 23 is provided with cutters for die-cutting the cigarette package.

[0036] In use, the cigarette package is laid on the bottom die, the combined structure of the outer frame 1 and the die plate 2 is buckled on the cigarette package, the cutters on the die plate 2 cooperate with the bottom die to die-cut the cigarette package, so that the cigarette package forms an outer package for packaging cigarettes or for packaging cigarette packets, at this time, the formed outer package is a planar unfolded structure, and the outer package forms a three-dimensional packaging box through folding.

[0037] In order to realize the connection of the outer frame 1 and the die plate 2, the related technology uses a jacking bolt and a locking nut on the second side edge 12 of the outer frame 1, the jacking bolt is jacked on the die plate 2 through the second side edge 12 of the outer frame 1, the die plate 2 is pressed on the first side edge 11 of the outer frame 1, and then the jacking bolt is locked by the locking nut. Generally, 6 to 8 jacking bolts need to be arranged on the second side edge 12 of the outer frame 1. The first side edge 11 and the second side edge 12 of the outer frame 1 are oppositely arranged side edges.

[0038] In order to prevent the loosening and displacement of the die plate 2, the jacking bolt needs to be jacked one by one to be rotationally fixed under normal circumstances, so that the heat generated by the equipment operation is transferred to the die plate 2 in the jacked state of the die plate 2, and the pressure in the die-cutting process also acts on the die plate 2, which is easy to cause the deformation and displacement of the whole die plate 2, the position of the die plate 2 and the bottom die changes, and the dark line offset or the product dark line breakage forms waste products.

[0039] Furthermore, because the operating personnel apply different forces, the tightness is different, and the displacement of the product is irregular, and it is difficult to eliminate the influence by amplifying the displacement error.

[0040] Therefore, the above-mentioned tightness of the template 2 by the tightening bolt makes the template 2 and the side of the outer frame 1 fixed in a pressing manner, which is easy to cause the middle position of the template 2 to be arched and deformed. Although the template 2 can be restored to be flat under the pressure of each time, repeated extrusion can also cause the displacement of the bottom die. Moreover, the pressure is also transmitted to the outer frame 1, which also causes the deformation of the outer frame 1 and the outward bulging of the outer frame 1, the appearance size of the outer frame 1 becomes larger, and the outer frame 1 cannot be pushed into the die cutting equipment for normal production.

[0041] Based on this, some embodiments of the utility model provide a die cutting device of a cigarette packaging piece for relieving the problem of template deformation.
