After the existing corrugated board cutting die cuts the board, sharp burrs are formed at the edge parts of the cuts, and the risk of scratching operators exists.

In order to alleviate the above-mentioned problem, the embodiment of the present disclosure provides a special-shaped cardboard die-cutting knife structure, can avoid forming sharp burr at incision edge portion when cutting the cardboard, can avoid scratch operation personnel like this. The board may be a single-pit board or a double-pit board, for example. The specific scheme is as follows:

Referring to fig. 1, an embodiment of the present disclosure provides a profiled cardboard die cutter structure 10 comprising: a blade portion 11 and a blade portion 12 connected to the bottom of the blade portion 11. Wherein the blade 12 is mainly used for preferentially cutting the board 20 to form a cut on the board 20. Specifically, the blade portion 11 includes a projecting sub-portion 111, the projecting sub-portion 111 may be provided to project from a side face of the blade portion 11, and the blade portion 12 is provided near the projecting sub-portion 111. Thus, referring to fig. 2, after the blade 12 cuts the cardboard 20 to form a notch, the tab 111 can be quickly pushed down on the large notch edge surface 21, so that the tab 111 is kept in surface-to-surface contact with the large notch edge surface 21, referring to fig. 3, and an arc bend is formed at the notch edge, so that the notch edge can be prevented from making line-to-surface moving contact with the large side surface of the blade 11. By way of example, a linear surface movement contact is understood here as a continuous movement of the side surface of the blade part 11 over the incision edge.

Compared with the cutter structure applied in the prior art, the special-shaped paperboard die-cutting cutter structure 10 of the embodiment of the disclosure has the advantages that the cutter body part 11 is additionally provided with the protruding sub-part 111, the protruding sub-part 111 is arranged close to the cutting edge part 12, and the protruding sub-part 111 protrudes from the large side surface of the cutter body part 11. Thus, when the blade 12 cuts the special-shaped paper board 20, the protrusion 111 is configured to press the large surface 21 of the cut edge, so that the protrusion 111 and the large surface 21 of the cut edge are kept in a surface-to-surface contact state, and the paper board 20 is curved at the cut edge, so that sharp burrs are not generated at the cut edge of the cut paper board 20, and an operator is not injured when performing the operation of the paper board 20.

In some embodiments, at least one of the protrusion 111 may be provided. The present application is not limited to the specific number of the protruding sub-portions 111, and is specifically determined according to the actual application requirements.

In some embodiments, at least one tab 111 is formed on at least one side of the lateral surface. In general, the large side surface of the blade 11 includes two sides, and according to the requirement of the cutting process, the protrusion 111 can be disposed on the large side surface of one side, so that the large side 21 of the incision edge on the side where the protrusion 111 is disposed can be pressed down, and sharp burrs on the edge of the cardboard 20 cut by the side are avoided. Alternatively, the protruding sub-portions 111 may be provided on both side surfaces, so that the cut edge surfaces 21 on both sides can be pressed down, and sharp burrs on the edges of the cardboard 20 cut on both sides can be avoided. The embodiment of the disclosure does not limit whether the protrusion 111 is simultaneously disposed on two sides of the large side, and may be determined according to practical application requirements.

In some embodiments, two protruding sub-portions 111 are provided, and the two protruding sub-portions 111 are respectively staggered on two sides of the large side surface; or alternatively

The two projecting sub-portions 111 are disposed at a distance from one another on the large side surface.

In this way, the requirements of different cardboard 20 cutting scenarios can be adapted. It can be appreciated that when two different paperboards 20 are cut, the two protruding sub-portions 111 in the embodiments of the disclosure can respectively press the large incision edge surfaces 21 of the two paperboards 20 according to application requirements, so as to ensure that sharp burrs cannot occur at each incision edge, and further enable operators not to scratch.

In some embodiments, with further reference to fig. 1, the outer profile of the tab portion 111 may be configured as an arc. In this way, the arcuate surface can be held in surface-to-surface contact with the cutout edge large surface 21.

In some embodiments, the tab 111 may be configured in a fan-shaped configuration; or the projection 111 may be constructed in a semicircular structure. In this way, the slit edge large face 21 can be further adapted and kept in face-to-face contact therewith.

In some embodiments, the sum of the height dimension of the tab portion 111 and the height dimension of the blade portion 12 is the thickness dimension of the shaped carton. By way of example, the height of an embodiment of the present disclosure may be understood as the direction of the height of the picture in fig. 1. In this way, the application of the cut of the cardboard 20 can be more matched, so that the tab 111 can press down the incision edge large surface 21.

In some embodiments, the height dimension of the blade 12 is one third of the thickness dimension of the shaped cardboard 20 and the height dimension of the tab 111 is two thirds of the thickness dimension of the shaped cardboard 20. In this way, it is possible to further ensure that the projection 111 presses down the slit edge large surface 21.

Firstly, the use method of the special-shaped cutter is not different from that of the straight cutter, and only the difference in the shape of the die cutter body is avoided, so that the special-shaped cutter is not different in production and manufacturing, and the special-shaped cutter is used according to the normal use mode of the straight cutter. Further, exemplary, commonly used cartons are generally classified into single-pit cartons (B-edges) and double-pit cartons (BC-edges), where the single-pit cartons are composed of single-pit cartons 20 and the double-pit cartons are composed of double-pit cartons 20. Wherein, the thickness of the single-pit paper board 20 of the B edge is 3mm, and the thickness of the double-pit paper board 20 of the BC edge is 6mm. The following describes the embodiment of the present disclosure further by taking the example that the length of the cutter blade is a, the semicircular diameter of the protrusion 111 is d, and the thickness of the corrugated board 20 is 2 t.

In order to make the outer contour pressing surface of the protrusion 111 work more fully, the overall length of the outer contour pressing surface and the blade edge portion 12 is just equal to the thickness of the corrugated board 20, so that sufficient contact and sufficient operation can be ensured, for the double-pit board 20, each layer of pit is required to be contacted by the outer contour pressing surface, then the blade edge a < t, and a+d=2t, when the B edge is used, 2t can be 3mm, a <1.5, a+d=3, and in order to ensure effective operation of the blade edge and sufficient contact of the pressing surface as possible, a=1 mm, d=2mm, namely the blade edge length a=1/3 (2 t), and the pressing surface diameter d=2/3 (2 t).

When using BC ridges, and similarly, 2t is 6mm, a <3, a+d=6, in order to ensure the effective operation of the blade and the contact of the pressing surface as full as possible, a=2 mm, d=4 mm is taken, that is, the blade length a=1/3 (2 t), the pressing surface diameter d=2/3 (2 t).

Therefore, for the double-pit and single-pit paperboards 20, the thicknesses of the paperboards 20 are different due to different pit types, in order to enable the outer profile pressing surface to play an effective role, the length of the die cutter is set to be L, the thickness of the paperboards 20 is set to be T, the length of the cutting edge is set to be 1/3*T, and the length of the semicircular pressing surface is set to be 2/3*T. Under normal conditions, even if the cutter is a straight cutter, the cutter needs to be replaced frequently, so that the special-shaped carton die cutter structure of the embodiment of the disclosure has no special consumption maintenance mode; in addition, even a double-pit carton is adopted, the radius of the outer contour pressing surface is 2mm, foam layers 40 are clamped on two sides of the carton during use, and the force for cutting off the carton is the same whether a straight cutter or a special cutter is adopted, so that the special carton die cutter structure of the embodiment of the disclosure only adds a pressing action of the outer contour pressing surface under the same equipment parameter conditions and processed objects. For the die-cutting knife, the die-cutting edge of the paper box can be optimized on the premise of realizing the basic function, so that the die-cutting knife is not sharp, and the die-cutting knife is also a humanized design.

The disclosed embodiment also provides a die cutter assembly, which comprises the special-shaped paperboard die cutter structure 10 provided above, and further comprises a wood board 30, wherein at least part of the cutter body 11 is structurally embedded in the wood board 30. This can facilitate the cutting process to the die-cutter structure.

In some embodiments, the die cutter assembly further comprises two foam layers 40, with the blade portion 11 and the blade portion 12 sandwiched between the two foam layers 40. When the actual cutting is performed, the foam layer 40 is preferentially contacted with the surface of the paperboard 20, and the foam layer 40 is compressed between the paperboard 20 and the board 30 in the process of cutting and moving the blade part 12 towards the paperboard 20, so that the effect of buffering potential energy is achieved.

The die cutter assembly of the embodiments of the present disclosure can achieve all effects of the above special-shaped paperboard die cutter structure 10, and is not described herein.

It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps recited in the present disclosure may be performed in parallel or sequentially or in a different order, provided that the desired results of the technical solutions of the present disclosure are achieved, and are not limited herein.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present disclosure, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The foregoing is merely specific embodiments of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the disclosure, and it is intended to cover the scope of the disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
