Description

Technical Field

[0001] This invention relates to the field of packaging processing technology, and in particular to a packaging die and die-cutting machine. Background Technology

[0002] With the continuous advancement and development of industrial technology, the design and manufacturing of packaging boxes have also undergone diversified and innovative changes. Today, a new type of packaging box has emerged on the market—the magnetic packaging box. The unique feature of this box is its ingenious use of magnetism to secure and open the packaging. The manufacturing process of magnetic packaging boxes is relatively complex, typically involving precisely cutting slots into cardboard and then embedding magnets within these slots. After the magnets are embedded, a layer of elegant wrapping paper is then applied to the surface of the cardboard, achieving both aesthetic appeal and practicality.

[0003] However, in existing production technologies, the process of creating magnet slots often relies on manual operation. This manual slotting method is not only inefficient but also makes it difficult to guarantee that the size and precision of each slot are completely consistent. The instability of manual slotting may result in magnets not fitting perfectly, thus affecting the overall quality of the packaging box and the user experience. Therefore, to improve production efficiency and ensure the dimensional accuracy of magnet slots, there is an urgent need to develop a mold specifically for creating magnet slot holes. Existing technologies also employ stamping to form magnet slots, such as... Figure 1 As shown, the stamped magnet groove has a large rounded corner between the vertical surface and the bottom surface, which causes the magnet to not fit the bottom surface of the magnet groove and to easily slide out of the magnet groove. Summary of the Invention

[0004] In view of the aforementioned shortcomings of current packaging die-cutting molds, this invention provides a packaging die-cutting mold that can precisely manufacture the slot according to the size requirements of the magnet slot, ensuring a perfect match between the magnet slot and the magnet, preventing the magnet from protruding from the cardboard, and maintaining the aesthetics of the packaging box. Furthermore, this die-cutting mold is suitable for mass production, effectively improving production efficiency.

[0005] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0006] A packaging die includes a base plate with a pre-shaped groove cutting position. An edge cutter is provided along the edge of the groove cutting position. A connecting structure is provided at a pre-defined position within the groove cutting position. A grooving device is detachably connected within the connecting structure. The grooving device is used to form a groove of a pre-shaped shape on the material when it is punched and grooved within the groove cutting position. The depth of the groove is adjusted by adjusting the grooving device.

[0007] According to one aspect of the present invention, the grooving device is specifically a grooving device, which includes a grooving cutter and a grooving block. The grooving block is adjustablely sleeved inside the grooving cutter, and the grooving cutter is detachably connected to the connecting structure.

[0008] According to one aspect of the invention, the grooving cutter includes a cutting edge and a sleeve, the cutting edge being connected to the sleeve, and the sleeve being detachably connected to the connecting structure.

[0009] According to one aspect of the invention, the groove pressing block is provided with an adjustment part, which is located at one end away from the blade.

[0010] According to one aspect of the invention, the end face of the grooved block located at one end of the blade is flush with or slightly lower than the end face of the blade.

[0011] According to one aspect of the present invention, the slotted block includes a stamping portion and a connecting portion, the stamping portion being disposed on the connecting portion.

[0012] According to one aspect of the present invention, the grooving device is specifically a grooving device, the grooving device including a drill bit and a motor, the drill bit being connected to the output end of the motor, and the drill bit being connected to the connecting structure.

[0013] According to one aspect of the invention, the drill bit is a hollow drill bit.

[0014] According to one aspect of the invention, an indentation knife for forming creases on the material is provided at a predetermined position within the groove cutting position.

[0015] A die-cutting machine includes a frame, on which a drive system is mounted. The drive system is connected to a die-cutting unit and drives the die-cutting unit to die-cut materials. The die-cutting unit includes the packaging die.

[0016] The advantages of this invention are as follows: The slotting cutter and slotting block allow the slotting cutter to cut the cardboard, while the slotting block stamps the cut cardboard to form a precisely sized magnet slot. This method ensures that the vertical and bottom edges of the magnet slot are free of rounded corners, allowing the magnet to perfectly fit the bottom of the slot. It also ensures that the top surface of the magnet is flush with the top surface of the cardboard, preventing protruding magnet parts during surface paper lamination and thus maintaining the appearance of the packaging box. Furthermore, it ensures the magnet's stability, preventing it from detaching from the cardboard. The connecting part, stamping part, blade, and sleeve allow the magnet slot to flexibly adapt to magnets of different shapes and sizes, significantly expanding the application range of packaging die-cutting molds. The outer edge cutter and creasing blade allow for one-time forming according to the size requirements of the packaging box, reducing the number of stamping processes and improving production efficiency. This packaging die-cutting mold ensures a perfect fit between the magnet and the magnet slot, thus maintaining the aesthetic appearance of the packaging box. It simultaneously reduces human error and labor intensity, further lowering production costs and improving economic efficiency. This invention introduces a packaging die-cutting mold that can precisely create the slot according to the size requirements of the magnet groove, ensuring a perfect match between the magnet groove and the magnet, preventing the magnet from protruding from the cardboard and maintaining the aesthetics of the packaging box. Furthermore, this die-cutting mold is suitable for mass production, effectively improving production efficiency. Attached Figure Description

[0031] Example 1:

[0032] like Figure 2 and Figure 3As shown, a packaging die-cutting mold is applicable to a magnetic packaging box, including a base plate 1. The base plate 1 can be made of wood or metal. The base plate 1 has a pre-shaped groove cutting position, and an edge cutter 3 is provided along the edge of the groove cutting position. The pre-shaped position is set according to the size and shape requirements of the magnetic packaging box. A connecting structure is provided at a pre-set position within the groove cutting position. A groove cutting device 2 is detachably connected within the connecting structure. The connecting structure can be a through hole, threaded hole, etc., provided on the base plate 1. The groove cutting device 2 is adjustablely mounted on the base plate 1. The groove cutting device 2 and the base plate 1 can be connected by a tight fit assembly. When adjustment is required, the distance between the end face of the groove cutting device 2 and the top surface of the base plate 1 can be adjusted by impact using a positioning tool. Alternatively, they can be connected by a threaded connection. Of course, the distance between the end face of the groove cutting device 2 and the top surface of the base plate 1 can also be achieved by connecting the groove cutting device 2 to a hydraulic cylinder, electric push rod, etc. The grooving device 2 includes a grooving blade 21 and a grooving block 22. The grooving block 22 is adjustablely fitted inside the grooving blade 21. The grooving block 22 and the grooving blade 21 can be connected by a threaded connection, and the distance between the end face of the grooving block 22 and the end face of the grooving blade 21 can be adjusted. Alternatively, the distance between the end face of the grooving block 22 and the end face of the grooving blade 21 can be adjusted by means of a hydraulic cylinder, an electric push rod, or by replacing the grooving block 22 with different lengths.

[0033] In this embodiment, the grooving blade 21 includes a cutting edge 211 and a sleeve 212. The cutting edge 211 is connected to the sleeve 212, and the sleeve 212 passes through the base plate 1. The sleeve is cylindrical, and the sleeve 212 has internal threads. The grooving block has external threads, and the sleeve 212 is threadedly connected to the surgical grooving block 22. Of course, the end of the grooving block 22 away from the cutting edge 211 can also be connected to a hydraulic cylinder, an electric push rod, etc., so that the grooving block 22 can move up and down within the sleeve 212 by being pushed by the hydraulic cylinder or the electric push rod.

[0034] In this embodiment, the slot pressing block 22 is provided with an adjustment part 221. The adjustment part 221 is located at the end away from the blade 211. The end face of the slot pressing block 22 at the end of the blade 211 is flush with or lower than the end face of the blade 211. Preferably, the end face of the slot pressing block 22 at the end of the blade 211 is slightly lower than the end face of the blade 211. Since the cardboard will form a certain thickness after being cut and pressed by the slot pressing block 22, it can avoid incomplete pressing. The adjustment part 221 can be a slotted groove or a cross groove, etc. The operator can adjust the distance between the end face of the slot pressing block 22 and the blade 211 with a screwdriver.

[0035] In this embodiment, the grooving blade 21 is forged from high-speed steel or tungsten steel, and the blade edge 211 is preferably V-shaped.

[0036] Working principle: The operator needs to adjust the height of the slotting device 2 relative to the top surface of the base plate according to the size requirements of the packaging box. Then, the die is installed on the packaging cutting equipment. After the equipment is started, the slotting blade 21 cuts the cardboard and the slotting block 22 presses the cardboard downward to form a magnetic slot.

[0037] Advantages of this embodiment: With the slotting cutter 21 and slotting block 22, the slotting cutter 21 cuts the cardboard, while the slotting block 22 stamps the cardboard cut by the slotting cutter 21 to form a precisely sized magnet slot. This method ensures that the vertical surface and bottom edge of the magnet slot have no rounded corners, allowing the magnet to perfectly fit the bottom surface of the slot. It also ensures that the top surface of the magnet is flush with the top surface of the cardboard, preventing protruding magnet parts during the lamination of the surface paper, thus not affecting the appearance of the packaging box. Simultaneously, it ensures the stability of the magnet, preventing it from falling off the cardboard. By having both the edge cutter and the slotting device located on the base plate, the outer dimensions of the packaging box and the magnet slot can be formed together, simplifying the process and improving production efficiency.

[0038] Example 2:

[0039] like Figure 3 and Figure 4As shown, a packaging die-cutting mold is applicable to a magnet packaging box, including a base plate 1. The base plate 1 can be made of wood or metal. The base plate 1 has a pre-shaped groove cutting position, and an edge cutter 3 is provided along the edge of the groove cutting position. The pre-shaped position is set according to the size and shape requirements of the magnet packaging box. A connecting structure is provided at a pre-set position within the groove cutting position. A groove cutting device 2 is detachably connected within the connecting structure. The connecting structure can be a through hole, threaded hole, etc., provided on the base plate 1. The groove cutting device 2 is adjustablely mounted on the base plate 1. The groove cutting device 2 and the base plate 1 can be connected by a tight fit assembly. When adjustment is required, the distance between the end face of the groove cutting device 2 and the top surface of the base plate 1 can be adjusted by impact using a positioning tool. Alternatively, it can be connected by a threaded connection. Of course, the distance between the end face of the groove cutting device 22 and the top surface of the base plate 1 can also be adjusted by connecting the groove cutting device 2 to a hydraulic cylinder, electric push rod, etc., to achieve the adjustment of the magnet groove depth. The grooving device 2 includes a grooving blade 21 and a grooving block 22. The grooving block 22 is adjustablely fitted inside the grooving blade 21. The grooving block 22 is connected to the grooving blade 21 by a threaded connection, and the distance between the end face of the grooving block 22 and the end face of the grooving blade 21 can be adjusted. The distance between the end face of the grooving block 22 and the end face of the grooving blade 21 can also be adjusted by means of a hydraulic cylinder, an electric push rod, or by replacing the grooving block 22 with different lengths.

[0040] In this embodiment, the grooving blade 21 includes a cutting edge 211 and a sleeve 212. The cutting edge 211 is connected to the sleeve 212, and the sleeve 212 passes through the base plate 1. The sleeve is cylindrical, and the sleeve 212 has internal threads. The grooving block has external threads, and the sleeve 212 is threadedly connected to the surgical grooving block 22. Alternatively, the end of the grooving block 22 away from the cutting edge 211 can be connected to a hydraulic cylinder, an electric push rod, etc., and the grooving block 22 can move up and down within the sleeve 212 by being pushed by the hydraulic cylinder or the electric push rod.

[0041] In this embodiment, when the magnet is not a circular magnet, such as a square magnet or an elliptical magnet, the slot pressing block 22 includes a stamping part 222 and a connecting part 223. The stamping part 222 is connected to the connecting part 223, and the connecting part 223 is threaded and threadedly connected to the inside of the sleeve 212. The stamping part 222 and the connecting part 223 can be connected by threads, or other feasible methods can be used, such as snap-fit ​​connection, welding, etc. The blade 211 and the stamping part 222 can be set according to the shape of the magnet.

[0042] In this embodiment, the slot pressing block 22 is provided with an adjustment part 221. The adjustment part 221 is located at the end away from the blade 211. The distance between the end face of the slot pressing block at the end of the blade 211 and the end face of the blade 211 can be adjusted by the adjustment part 221. The end face of the slot pressing block 22 at the end of the blade 211 is flush with or lower than the end face of the blade 211. Preferably, the end face of the stamping part 222 at the end of the blade 211 is slightly lower than the end face of the blade 211. Since the cardboard will form a certain thickness after being cut and stamped by the slot pressing block 22, it can avoid incomplete stamping. The adjustment part 221 can be a slotted groove or a cross groove, etc. The operator can adjust the distance between the end face of the slot pressing block 22 and the blade 211 with a screwdriver.

[0043] In this embodiment, the grooving blade 21 is forged from high-speed steel or tungsten steel, and the blade edge 211 is preferably V-shaped.

[0044] In this embodiment, a creasing knife 4 is provided at a predetermined position within a pre-defined groove, for pressing creases on the board / face paper. The predetermined position is the crease position according to the shape of the packaging box. The end face of the creasing knife 4 is preferably flat or arc-shaped. By setting the creasing knife 4, the material can be folded into a box shape according to the creases, which facilitates the processing of the next step.

[0045] Working Principle: Operators need to adjust the height of the slotting device 2, outer edge cutter 3, and creasing knife 4 relative to the top surface of the base plate according to the size requirements of the packaging box. Then, the die is installed on the packaging cutting equipment. After starting the equipment, the slotting device 2, outer edge cutter 3, and creasing knife 4 work together to precisely cut the cardboard. The outer edge cutter 3 is responsible for cutting the cardboard into the preset shape, while the creasing knife 4 is responsible for pressing out the creases. The slotting cutter 21 in the slotting device 2 cuts the cardboard and presses it downwards through the slotting block 22, thereby forming a magnetic slot.

[0046] Advantages of this embodiment: With the slotting cutter 21 and slotting block 22, the slotting cutter 21 cuts the cardboard, while the slotting block 22 stamps the cardboard cut by the slotting cutter 21 to form a precisely sized magnet slot. This method ensures that the vertical surface and bottom edge of the magnet slot have no rounded corners, allowing the magnet to perfectly fit the bottom surface of the slot. It also ensures that the top surface of the magnet is flush with the top surface of the cardboard, preventing protruding magnet parts during surface paper lamination and thus not affecting the appearance of the packaging box. Simultaneously, it ensures the stability of the magnet, preventing it from falling off the cardboard. Through the connection part, stamping part, blade, and sleeve, the magnet slot can flexibly adapt to magnets of different shapes and sizes, significantly expanding the application range of packaging die-cutting molds. With the outer edge cutter and creasing knife, one-time forming can be achieved according to the size requirements of the packaging box, thereby reducing the number of stamping processes and improving production efficiency.

[0047] Example 3:

[0048] like Figure 5 and Figure 6 As shown, a packaging die-cutting mold is applicable to a magnetic packaging box, including a base plate 1. The base plate 1 can be made of wood or metal. The base plate 1 has a pre-shaped groove cutting position, and an edge cutter 3 is provided along the edge of the groove cutting position. The pre-shaped position is set according to the size and shape requirements of the packaging box design. A connecting structure is provided at a pre-defined position within the groove cutting position. A detachable drilling device 6 is connected within the connecting structure. The connecting structure can be a through hole, threaded hole, etc., provided on the base plate 1. The drilling device 6 includes a drill bit 61 and a motor 62. The drill bit 61 is telescopically mounted on the motor 62, and the motor 62 is fixedly mounted on the base plate 1. Preferably, a telescopic shaft is connected between the drill bit 61 and the output shaft of the motor 62 to facilitate adjustment of the distance between the drill bit 61 and the top surface of the base plate, thereby adjusting the groove depth. Preferably, the motor 62 is arranged horizontally to facilitate the motor's power cable passing through the groove on the base plate 1.

[0049] In this embodiment, a creasing knife 4 is provided at a predetermined position within a pre-defined groove, for pressing creases on the board / face paper. The predetermined position is the crease position according to the shape of the packaging box. The end face of the creasing knife 4 is preferably flat or arc-shaped. By setting the creasing knife 4, the material can be folded into a box shape according to the creases, which facilitates the processing of the next step.

[0050] In this embodiment, the drill bit 61 is a hollow drill bit, a core drill bit, etc. When drilling holes in the cardboard, the hollow drill bit and the core drill bit facilitate the smooth discharge of chips and do not affect the depth of the edge cutter 3 and the creasing cutter 4.

[0051] Working Principle: Operators need to adjust the height of the outer edge cutter 3 and the creasing knife 4 relative to the top surface of the base plate according to the size requirements of the packaging box. Then, the die is installed on the packaging cutting equipment. After starting the equipment, the grooving device 6, the outer edge cutter 3, and the creasing knife 4 work together to precisely cut the cardboard. The outer edge cutter 3 is responsible for cutting the cardboard into the preset shape, while the creasing knife 4 is responsible for pressing out the creases. The drill bit inside the grooving device 6 cuts the cardboard and presses it downwards through the groove pressing block 22, thereby forming a magnetic groove.

[0052] Advantages of this implementation: The drill bit 61 and motor 62 provide power, while the drill bit 61 cuts the cardboard to form precisely sized magnet slots. This method ensures that the vertical surface and bottom edge of the magnet slot have no rounded corners, allowing the magnet to fit perfectly against the bottom surface of the slot. It also ensures that the top surface of the magnet is flush with the top surface of the cardboard, preventing protruding magnet parts during surface paper lamination and thus preserving the appearance of the packaging box. Furthermore, it ensures the magnet's stability, preventing it from detaching from the cardboard. The use of hollow and core-splitting drill bits facilitates the smooth removal of chips without affecting the depth of the edge cutter 3 and creasing knife 4. The outer edge cutter and creasing knife allow for one-time molding according to the size requirements of the packaging box, reducing processing steps and improving production efficiency.

[0056] The advantages of this embodiment are: by setting a packaging die on the die-cutting unit, the cutting of packaging materials and the slotting of magnetic grooves can be completed efficiently and accurately, thus improving production efficiency.

[0057] The advantages of this invention are as follows: The slotting cutter and slotting block allow the cardboard to be cut by the slotting cutter, while the slotting block presses the cut cardboard into precisely sized magnetic slots. This method ensures that the vertical and bottom edges of the magnetic slot have no rounded corners, allowing the magnet to fit perfectly against the bottom of the slot. It also ensures that the top surface of the magnet is flush with the top surface of the cardboard, preventing protruding magnets during surface paper lamination, which would affect the appearance of the packaging box. Furthermore, it ensures the magnet's stability, preventing it from detaching from the cardboard. Similarly, the drill bit and motor provide power, while the drill bit cuts the cardboard to create precisely sized magnetic slots. This method also ensures that the vertical and bottom edges of the magnetic slot have no rounded corners, allowing the magnet to fit perfectly against the bottom of the slot. It also ensures that the top surface of the magnet is flush with the top surface of the cardboard, preventing protruding magnets during surface paper lamination, which would affect the appearance of the packaging box. Finally, it ensures the magnet's stability, preventing it from detaching from the cardboard. By incorporating connecting parts, stamping parts, cutting edges, and sleeves, the magnetic groove can flexibly adapt to magnets of different shapes and sizes, significantly expanding the application range of packaging die-cutting molds. The outer edge cutting blade and creasing blade allow for one-time molding according to the size requirements of the packaging box, reducing processing steps and improving production efficiency. This packaging die-cutting mold ensures a perfect fit between the magnet and the magnetic groove, thus maintaining the aesthetic appearance of the packaging box.
