[0002] Cardboard, a thick sheet of paper made from various pulps and interwoven with fibers, is the primary material for cartons. Cardboard boxes currently on the market come in a variety of shapes and are highly aesthetic. To achieve this, the cardboard requires certain processing, including die-cutting, which involves using a die-cutting device to cut the cardboard into specific lengths or shapes.

[0003] A wine box cardboard die-cutting knife disclosed in Chinese patent CN207789841U includes a base plate and a trimming knife. The trimming knife includes two vertical trimming knives and two horizontal trimming knives. The two vertical trimming knives and the two horizontal trimming knives form a rectangle. A cover plate cutter and a cover plate cutter are provided on the base plate between the two vertical trimming knives. The cover plate cutter and the cover plate cutter are respectively provided with multiple notches, and the multiple notches are evenly arranged on the cover plate cutter and the cover plate cutter.

[0004] Existing cardboard die-cutting devices place the cardboard directly on top of the trimming knife and use a pressure plate to press down on the cardboard for die-cutting. However, when processing wine boxes that require fasteners, the pressure plate is flat. After the trimming knife cuts the cardboard, the fastener installation area is not completely cut. Workers need to stack and organize the cut cardboard and then cut the fasteners from the other side. Furthermore, when moving the cardboard, not every cardboard position is perfectly aligned with the fastener cutting knife. If there is any deviation, the fastener holes will be non-standard, which is not conducive to subsequent fastener assembly and fails to meet anti-counterfeiting and production standards.

[0005] In order to solve the above problems, the utility model proposes a cardboard die-cutting device. Utility Model Content

[0006] In order to solve the problems existing in the background technology, the utility model proposes a cardboard die-cutting device.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows: comprising an upper template and a lower template, the upper template and the lower template correspond to each other up and down, and the bottom of the upper template is fixedly connected to a cardboard die-cutting knife and a fastener die-cutting knife;

[0008] A carving knife is fixedly provided on the top of the lower template, and the carving knife corresponds to the fastener die cutting knife in the upper and lower parts.

[0009] Furthermore, there are several cardboard die-cutting knives, which are arranged in a straight line at the bottom of the upper template. The number of cardboard die-cutting knives, fastener die-cutting knives and engraving knives is equal, and the engraving knives and fastener die-cutting knives correspond to each other one by one up and down.

[0010] Furthermore, the cardboard die-cutting knife, fastener die-cutting knife and engraving knife are all arranged in a square shape, and the fastener die-cutting knife is located inside the corresponding cardboard die-cutting knife.

[0011] Furthermore, each of the cardboard die-cutting knives is fixedly connected to a positioning die-cutting knife, the positioning die-cutting knife is arranged in a U shape, and each positioning die-cutting knife is provided with a plurality of through holes at intervals;

[0012] Both ends of the positioning die-cutting knife are fixedly connected to the cardboard die-cutting knife, and the fastener die-cutting knife is located inside the corresponding positioning die-cutting knife.

[0013] Furthermore, a first resilient member is provided on the outside of each cardboard die-cutting knife, which is fixedly connected to the bottom of the upper template. The first resilient member slides with the corresponding cardboard die-cutting knife, and the height of the first resilient member is equal to the height of the cardboard die-cutting knife.

[0014] Furthermore, a second rebound member is provided on the outside of each positioning die-cutting knife, which is fixedly connected to the bottom of the upper template.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: a cardboard die-cutting device includes an upper template 1 and a lower template 8, which correspond to each other up and down. A cardboard die-cutting knife 2 and a fastener die-cutting knife 4 are fixedly connected to the bottom of the upper template 1.

[0027] There are several cardboard die-cutting knives 2, which are arranged in a straight line at the bottom of the upper template 1. This allows the multiple cardboard die-cutting knives 2 to work together and increase production.

[0028] Each cardboard die-cutter 2 is provided with a first resilient member 5, fixedly connected to the bottom of the upper template 1. The first resilient member 5 slides with the corresponding cardboard die-cutter 2, and its height is equal to that of the cardboard die-cutter 2. When the cardboard die-cutter 2 is cutting the cardboard, the cardboard obstruction compresses the first resilient member 5. After cutting, the first resilient member 5 rebounds to the outside of the cardboard die-cutter 2, protecting the cardboard die-cutter 2.

[0029] A carving knife 9 is fixed to the top of the lower template 8, aligned with the fastener die-cutter 4. This allows the carving knife 9 and the fastener die-cutter 4 to cooperate and cut the entire fastener installation area in one go. A fastener is a connecting part between two components. The fasteners on wine packaging are used to secure and protect the wine bottle.

[0030] The number of the cardboard die-cutting knife 2, the fastener die-cutting knife 4 and the engraving knife 9 is equal, and the engraving knife 9 corresponds one by one to the fastener die-cutting knife 4. The cardboard die-cutting knife 2, the fastener die-cutting knife 4 and the engraving knife 9 are all arranged in a square shape.

[0031] The bottom of the carving knife 9 is fixedly connected with a mounting plate, and the mounting plate is bonded to the lower template 8 by glue. The mounting plate is bonded to the lower template 8 by glue, and then the carving knife 9 is fixed on the lower template 8. The carving knife 9 is bonded by glue so that the carving knife 9 can be replaced.

[0032] A fourth resilient member is disposed within the engraving tool 9 and is fixedly connected to the top of the mounting plate. The top surface of the fourth resilient member is flush with the top surface of the engraving tool 9 or slightly lower than the top surface of the engraving tool 9. This allows the fourth resilient member to rebound after the engraving tool 9 has cut.

[0033] The fastener die-cutting knife 4 is located inside the corresponding cardboard die-cutting knife 2 .

[0034] Each fastener die-cutter 4 is internally provided with a third resilient member 7, which is fixedly connected to the bottom of the upper template 1. The third resilient member 7 slides in engagement with the corresponding fastener die-cutter 4. When the fastener die-cutter 4 is die-cutting cardboard, the cardboard obstructs and compresses the third resilient member 7. After cutting, the third resilient member 7 rebounds to the outside of the fastener die-cutter 4, protecting the fastener die-cutter 4.

[0035] Each cardboard die-cutter 2 is fixedly connected to a positioning die-cutter 3. The positioning die-cutter 3 is U-shaped and has several spaced through holes. This leaves a U-shaped cut line on the cardboard after the positioning die-cutter 3 cuts, making it easier to attach the cut cardboard to other components. These other components are the components of the wine box mentioned in the background.

[0036] Both ends of the positioning die-cutting knife 3 are fixedly connected to the cardboard die-cutting knife 2, so that the positioning die-cutting knife 3 cooperates with the cardboard die-cutting knife 2 to perform cardboard die-cutting. The fastener die-cutting knife 4 is located inside the corresponding positioning die-cutting knife 3.

[0037] Each positioning die-cutter 3 is externally provided with a second resilient member 6, fixedly connected to the bottom of the upper mold plate 1. The second resilient member 6 slidably engages the corresponding positioning die-cutter 3, and its height is equal to that of the positioning die-cutter 3. When the positioning die-cutter 3 cuts the cardboard, the cardboard obstructs and compresses the second resilient member 6. After cutting, the second resilient member 6 rebounds to the outside of the positioning die-cutter 3, protecting it.

[0038] The first, second, third, and fourth resilient members 5, 6, 7, and 7 are all made of polyurethane, a material characterized by high density, strength, toughness, and wear resistance. The cardboard die-cutting blade 2, fastener die-cutting blade 4, engraving blade 9, and positioning die-cutting blade 3 are all precision-machined from wear-resistant steel.

[0039] Working principle:

[0040] When in use, the cardboard is placed on top of the lower template 8, and the carving knife 9 is located at the bottom of the cardboard.

[0041] Press the upper template 1 downward to move it toward the top of the cardboard. The upper template 1 drives the cardboard die-cutting knife 2, the positioning die-cutting knife 3, and the fastener die-cutting knife 4 to move to the top of the cardboard, so that the cardboard die-cutting knife 2, the positioning die-cutting knife 3, and the fastener die-cutting knife 4 press the cardboard downward to cut.

[0042] When the cardboard die-cutting knife 2 , the positioning die-cutting knife 3 and the fastener die-cutting knife 4 press the cardboard downward, the first resilient member 5 , the second resilient member 6 and the third resilient member 7 are compressed due to the obstruction of the cardboard.

[0043] Since the fastener die cutter 4 is die cutting the top of the cardboard, it will press the cardboard downwards, so that the engraving knife 9 is synchronously cut from the bottom of the cardboard. The engraving knife 9 cooperates with the fastener die cutter 4 to make the cutting of the fastener synchronous, the pressure is even, and the cutting position is more accurate.

[0044] After the cutting is completed, the upper template 1 is moved upward, and the cardboard die-cutting knife 2, the positioning die-cutting knife 3 and the fastener die-cutting knife 4 are moved upward and away from the cardboard, so that the first resilient member 5, the second resilient member 6 and the third resilient member 7 rebound. The die-cut cardboard and the cardboard fastener can be removed so that the staff can install the fastener at the cutting position of the engraving knife 9.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
