Description

Technical Field

[0001] This utility model relates to the field of cardboard printing and packaging technology, specifically to an anti-deviation die-cutting component. Background Technology

[0002] During the production and processing of cardboard packaging boxes, the printing process begins with printing the cardboard flat. After printing, the cardboard is cut into specific shapes and then folded into boxes for packaging. The cutting step typically involves die-cutting, where the cardboard is placed on a steel die and cut using a die. Because the design is already printed before cutting, high precision is required; even small deviations can significantly impact the final appearance of the packaged product.

[0003] A published Chinese patent, publication number CN206999736U, discloses a steel bottom mold, comprising: a steel plate body, wherein the steel plate body is provided with a hollow groove, the thickness of the steel plate body is 1.4mm, and the depth of the hollow groove is equal to the thickness of the steel plate body.

[0004] The steel bottom mold used in the above patent cannot fix the cardboard during the die-cutting process. The cardboard is prone to displacement during the die-cutting process, which causes the die-cutting force to not be able to cut the cardboard completely at the moment of die-cutting, thus affecting the cutting effect of the cardboard. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an anti-deviation die-cutting component to solve the problem that cardboard is prone to deviation during the die-closing process in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides an anti-deviation die-cutting component, including a steel base mold and a die-cutting mold. The steel base mold has several evenly distributed die-cutting areas, and the edges of the die-cutting areas are provided with tangent grooves. The die-cutting mold has several die-cutting tools distributed corresponding to the die-cutting areas, and the inner side of the die-cutting tools is provided with indentation lines.

[0007] The steel bottom mold is provided with a pressing protrusion, which is distributed on the inner side of the die-cutting area. When the die-cutting mold closes relative to the steel bottom mold, the die-cutting tool cuts into the tangent groove to cut the cardboard placed in the die-cutting area. The pressing protrusion abuts against the area of ​​the die-cutting mold located on the inner side of the die-cutting tool and instantly bites the cardboard to fix the die-cutting position of the cardboard between the steel bottom mold and the die-cutting mold.

[0008] In one embodiment of the present invention, the die-cutting area includes a lid area, a first connecting area, a rear panel area, a second connecting area, and a front panel area arranged sequentially.

[0009] The pressing protrusions include a first pressing protrusion and a second pressing protrusion. The first pressing protrusion is distributed on both sides of the lid area, and the second pressing protrusion is distributed on both sides of the front panel area.

[0010] In one embodiment of this utility model, the pressing protrusion is an engraved frosted protrusion.

[0011] In one embodiment of this utility model, the pressing protrusion is a corrugated textured protrusion.

[0012] In one embodiment of the present invention, the die is provided with toothed lines in the area between the die-cutting tool and the indentation line, and the toothed lines correspond to the two sides of the rear panel area on the upper part of the steel bottom die.

[0013] In one embodiment of this utility model, the height of the pressing protrusion is greater than the die-cutting thickness after the die-cutting tool cuts into the tangent groove.

[0014] In one embodiment of the present invention, the steel bottom mold is provided with assembly holes, and there are at least four assembly holes, which are evenly distributed near the edge of the steel bottom mold.

[0015] In one embodiment of the present invention, a positioning groove is provided on one side of the steel bottom mold and a positioning pile is provided on one side of the die-cutting mold. After the die-cutting mold and the steel bottom mold are closed, the positioning pile and the positioning groove lock the mold closing position.

[0016] As described above, the anti-deviation die-cutting component of this utility model has the following beneficial effects:

[0017] This invention increases the paper-pressing friction between the die-cutting mold and the steel base mold by setting pressing protrusions with engraved frosted or wavy texture effects. During the die-cutting process, the die-cutting mold instantly bites the cardboard and quickly and synchronously completes the die-cutting, avoiding the problem of the cardboard not being completely cut by the die-cutting force at the moment of die-cutting due to the cardboard shifting during the die-cutting process, thus improving the cardboard cutting effect. In addition, no paper dust is left on the edge of the cardboard after it is quickly cut, which has a qualitative improvement on the cardboard die-cutting effect and yield.

Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0025] Please see Figures 1 to 4 It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0026] Please see Figures 1-4 This utility model provides an anti-deviation die-cutting component, including a steel base mold 1 and a die 2. The steel base mold 1 is provided with mounting holes 14, and there are at least four mounting holes 14. The mounting holes 14 are evenly distributed near the edge of the steel base mold 1, which facilitates the installation and use of the steel base mold 1 on the production line. The steel base mold 1 is provided with several evenly distributed die-cutting areas 11, and the edges of the die-cutting areas 11 are provided with tangent grooves 12. Specifically, the die-cutting area 11 includes a box cover area 111, a first connecting area 112, a rear panel area 113, a second connecting area 114, and a front panel area 115 arranged in sequence. The box cover area 111, the first connecting area 112, the rear panel area 113, the second connecting area 114, and the front panel area 115 can be folded to form multiple panels of a packaging box. The die 2 is provided with several die-cutting cutters 21 distributed corresponding to the die-cutting areas 11. The inner side of each die-cutting cutter 21 has a creasing line 22. When the die 2 closes relative to the steel base mold 1, the die-cutting cutters 21 cut into the tangent groove 12 to cut the cardboard placed in the die-cutting area 11. Simultaneously, the creasing line 22 presses out folds on the cardboard, allowing the cardboard to be cut and creasing in one step. The steel base mold 1 and die 2, working together, can simultaneously die-cut and creasing multiple cardboards, greatly improving the efficiency of the die-cutting assembly in processing cardboard. One side of the steel base mold 1 has a positioning groove 15, and one side of the die 2 has a positioning pin 24. After the die 2 and steel base mold 1 close, the positioning pin 24, in conjunction with the positioning groove 15, locks the closing position, improving the processing effect of the die-cutting assembly in cutting multiple cardboards at once.

[0027] The die 2 is provided with toothed lines 23 in the area between the die-cutting tool 21 and the creasing line 22. The toothed lines 23 correspond to both sides of the back panel area 113 on the steel bottom die 1. The toothed lines 23 perform a sawing motion on both sides of the back panel of the cardboard, which can make the image lines on the side of the printed packaging box clearer, thereby enhancing the overall aesthetics of the printed packaging box.

[0028] The steel base mold 1 is provided with a pressing protrusion 13, which is an engraved frosted protrusion or a corrugated texture protrusion. The height of the pressing protrusion 13 is greater than the die-cutting thickness after the die-cutting tool 21 cuts into the tangent groove 12. The pressing protrusion 13 is distributed on the inner side of the die-cutting area 11. When the die 2 closes relative to the steel base mold 1, the die-cutting tool 21 cuts into the tangent groove 12 to cut the cardboard placed in the die-cutting area 11. The pressing protrusion 13 abuts against the area of ​​the die 2 located inside the die-cutting tool 21 and instantly bites the cardboard to fix the die-cutting position of the cardboard between the steel base mold 1 and the die 2. This avoids the problem that the die-cutting force cannot completely cut the cardboard at the moment of die-cutting due to the cardboard shifting during the die-cutting process, and improves the anti-deviation effect of the cardboard during the die-cutting process. The pressing protrusion 13 includes a first pressing protrusion 131 and a second pressing protrusion 132. The first pressing protrusion 131 is distributed on both sides of the lid area 111, and the second pressing protrusion 132 is distributed on both sides of the front panel area 115. The first pressing protrusion 131 and the second pressing protrusion 132 cooperate to position the cardboard at both ends, further improving the anti-deviation effect of the cardboard during the die-cutting process.

[0029] In summary, this invention, by setting pressing protrusions 13 with engraved frosted or wavy texture effects, increases the paper-pressing friction between the die-cutting mold 2 and the steel base mold 1. During the die-cutting process where the die-cutting mold 2 closes relative to the steel base mold 1, it instantly engages the cardboard, quickly and synchronously completing the die-cutting. This avoids the problem of insufficient cutting force during the die-cutting process due to cardboard misalignment, thus improving the cardboard cutting effect. Furthermore, after rapid cutting, no paper dust or edge residue remains on the cardboard, significantly improving the die-cutting effect and yield. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
