[0045] For cardboard boxes, during the production process, considering the requirements of the manufacturing process, it is necessary to create creases in the cardboard to facilitate assembly by workers. Because the shapes of these creases vary, it is difficult for workers to create them by folding and turning the cardboard, resulting in cumbersome processing, low efficiency, and a risk of damaging the cardboard.

[0046] In view of this, the present invention provides a high-efficiency cardboard creasing device, wherein a first creasing part is provided on a first mold and a second creasing part is provided on a second mold, thereby creating corresponding creasing marks on the cardboard according to the needs of the workers and improving the processing efficiency of the workers.

[0047] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a high-efficiency cardboard creasing device, which is used to create indentations on cardboard. The cardboard has a first side and a second side facing each other. The high-efficiency cardboard creasing device includes:

[0049] The first mold 10 is used to hold the cardboard;

[0050] The second mold 20 is movably mounted on the first mold 10; and

[0051] The clamping structure 30 includes a first clamping portion 31 disposed on the first mold 10 and a second clamping portion 32 disposed on the second mold 20. The first clamping portion 31 abuts against the first surface, and the second clamping portion 32 abuts against the second surface. The second clamping portion 32 cooperates with the first clamping portion 31 to create a clamping mark on the cardboard.

[0052] In this embodiment, the first mold 10 serves as a fixed support platform, its surface adhering to the first side of the cardboard. The second mold 20, through its movable design, allows for vertical or horizontal movement, forming a dynamic cooperation space with the first mold 10 to ensure precise alignment of the clamping structure 30. The clamping structure 30 creates clamping marks on the cardboard. It is understood that the first clamping portion 31 contacts the first side of the cardboard, guiding the direction of fiber deformation. Furthermore, the second clamping portion 32 transmits pressure to simultaneously stress both sides of the cardboard, forming clamping lines, thus accommodating clamping requirements with composite layers or irregularly shaped structures. The technical solution proposed in this embodiment reduces processing actions for irregularly shaped clamping marks, improves processing efficiency, and reduces the risk of cardboard damage.

[0053] Specifically, the high-efficiency cardboard creasing device includes a first mold 10, a second mold 20, and a creasing structure 30.

[0054] The first mold 10 has a flat surface for placing cardboard and has a certain load-bearing capacity, providing support. The second mold 20 is movably mounted on the first mold 10 and can be brought into contact with and separated from the first mold 10 by external force, thereby applying pressure to both sides of the cardboard. The clamping structure 30 is used to guide the fiber deformation direction of the cardboard, thereby creating clamping marks. The first clamping part 31 and the second clamping part 32 are respectively disposed on the opposite side of the first mold 10 and the second mold 20. The shape of the first clamping part 31 and the second clamping part 32 can be circular, square, or irregular, and is not limited here. The position of the first clamping part 31 and the second clamping part 32 can be close to the edge of the first mold 10 and the second mold 20 or close to the center of the first mold 10 and the second mold 20, and is not limited here. It can be set according to the needs of the operator, as long as the shape and position of the first clamping part 31 and the second clamping part 32 correspond.

[0055] Furthermore, in one embodiment of this utility model, one of the first clamping portion 31 and the second clamping portion 32 is a clamping protrusion, and the other is a clamping groove; and / or,

[0056] Both the first clamping portion 31 and the second clamping portion 32 are clamping protrusions; and / or,

[0057] Both the first clamping portion 31 and the second clamping portion 32 are clamping grooves.

[0058] In the technical solution adopted in this embodiment, when one of the first clamping portion 31 and the second clamping portion 32 is a clamping protrusion and the other is a clamping groove, a mortise-and-tenon interlocking structure can be formed. The protrusion is embedded into the groove to guide the shaping and deformation of the cardboard fibers, significantly improving the clarity of the clamping line. It should be noted that the groove needs to be designed to accommodate the extension of the cardboard under pressure, reducing breakage or burrs caused by excessive fiber stretching. When both the first clamping portion 31 and the second clamping portion 32 are clamping protrusions, the first and second surfaces of the cardboard are simultaneously pressed, forming symmetrical deformation zones, which can satisfy the deep indentation processing of the cardboard. When both the first clamping portion 31 and the second clamping portion 32 are clamping grooves, the two clamping grooves form a negative space clamping, reducing direct pressure on the cardboard surface, which can satisfy the shallow indentation processing of the cardboard.

[0059] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of the present invention, the first mold 10 includes a first mold body 11 and a first clamping plate 12 detachably connected to the first mold body 11.

[0060] The second mold 20 includes a second mold body 21 and a second clamping plate 22 that is detachably connected to the second mold body 21;

[0061] The first clamping part 31 is provided on the first clamping plate 12, and the second clamping part 32 is provided on the second clamping plate 22.

[0062] In this embodiment, the first mold 10 may include a first mold body 11 and a first clamping plate 12. Correspondingly, the second mold 20 may include a second mold body 21 and a second clamping plate 22. In this embodiment, the first mold body 11 and the first clamping plate 12 can be connected by bolts or clips, and the second mold body 21 and the second clamping plate 22 can be connected by bolts or clips, which allows for quick replacement of the first clamping part 31 and the second clamping part 32 to meet different clamping requirements.

[0063] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of the present invention, the clamping film tool further includes a positioning structure, which includes a first positioning component 40 and a second positioning component 50 that are independently arranged with each other; the first positioning component 40 includes a first positioning part disposed on the first mold body 11 and a first mating part disposed on the first clamping plate 12.

[0064] The second positioning component 50 includes a second positioning part disposed on the second mold body 21 and a second mating part disposed on the second clamping plate 22;

[0065] The first positioning part cooperates with the first mating part, and the second positioning part cooperates with the second mating part.

[0066] In this embodiment, the high-efficiency cardboard creasing device may further include a positioning structure to achieve rapid alignment between the first creasing plate 12 and the first mold body 11, and between the second creasing plate 22 and the second mold body 21, thereby further improving processing efficiency. In this embodiment, the positioning structure includes a first positioning component 40 and a second positioning component 50. The first positioning component 40 and the second positioning component 50 may employ a T-shaped groove or a tapered positioning pin structure. Correspondingly, the first mating part and the second mating part may employ a T-shaped slider or a positioning hole. This effectively constrains the first creasing plate 12 and the second creasing plate 22, limiting the offset of either the first creasing plate 12 or the second creasing plate 22 and ensuring the consistency of the creasing marks.

[0067] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of this utility model, one of the first positioning part and the first mating part is a positioning protrusion, and the other is a positioning groove; and / or,

[0068] One of the second positioning part and the second mating part is a positioning protrusion, and the other is a positioning groove.

[0069] In this embodiment, the technical solution employs a configuration such that when the first clamping plate 12 is attached to the surface of the first mold body 11 or the second clamping plate 22 is attached to the surface of the second mold body 21, the positioning protrusion engages with the positioning groove to restrict the lateral or longitudinal displacement of the first clamping plate 12 or the second clamping plate 22, forming a bidirectional constraint. The positioning engagement achieved through the positioning protrusion and positioning groove is structurally simple and offers good stability. It is understood that the positioning groove can completely cover the positioning protrusion, thereby ensuring a tight fit between the first mold body 11 and the first clamping plate 12, or between the second mold body 21 and the second clamping plate 22.

[0070] Furthermore, refer to Figure 2 In one embodiment of this utility model, the high-efficiency cardboard creasing device further includes a magnetic structure 60, which is disposed on the first mold body 11 and used to attract the first creasing plate 12; and / or,

[0071] A magnetic structure 60 is provided on the second mold body 21 to attract the second clamping plate 22.

[0072] In this embodiment, the magnetic structure 60 allows the first clamping plate 12 to be fixed to the first mold body 11, or the second clamping plate 22 to be fixed to the second mold body 21. In this embodiment, the magnetic structure 60 can be a magnet. Mounting holes can be made on the surface of the first mold body 11 or the second mold body 21, and the magnet can be embedded in the mounting holes. The magnetic attraction allows for quick assembly and disassembly of the first clamping plate 12 from the first mold body 11, and the second clamping plate 22 from the second mold body 21. It should be noted that the side of the first clamping plate 12 facing the first mold body 11 and the side of the second clamping plate 22 facing the second mold body 21 can be made of metal, allowing them to be magnetically attracted to the magnet. The magnet can be one or more; this is not limited here.

[0073] Furthermore, refer to Figure 1 In one embodiment of this utility model, the cardboard has an adjacent first long side and a first short side, the second mold body 21 has an adjacent second long side and a second short side, and the cardboard high-efficiency creasing device further includes a limiting structure 70, which includes:

[0074] A first retaining edge 71 is disposed on the first mold body 11 to abut against the first long edge and the second long edge; and

[0075] The second stop 72 is provided on the first mold body 11 to abut against the first short side and the second short side.

[0076] In this embodiment, the high-efficiency cardboard creasing device further includes a limiting structure 70. In this embodiment, the limiting structure 70 includes a first stop 71 and a second stop 72. The first stop 71 simultaneously constrains the displacement of the first long side of the cardboard and the second long side of the second mold body 21. The second stop 72 simultaneously constrains the displacement of the first short side of the cardboard and the second short side of the second mold body 21. This configuration reduces the cardboard offset during the creasing process, thereby improving the creasing effect. Simultaneously, it can reduce calibration time and improve creasing processing efficiency to a certain extent.

[0077] Furthermore, in one embodiment of this utility model, the first retaining edge 71 and the first mold body 11 are integrally formed; and / or,

[0078] The second retaining edge 72 and the second mold body 21 are integrally formed.

[0079] In this embodiment, the technical solution employs this configuration to reduce the number of components, simplify the overall design, and lower design complexity. Simultaneously, it reduces the number of connection points between components, thereby reducing potential failure points and improving product reliability. Furthermore, a unibody structure is generally more robust, providing better stability and durability.

[0080] Furthermore, refer to Figure 1 In one embodiment of the present invention, the high-efficiency cardboard creasing device further includes a stamping structure 80, which is movably connected to the first mold 10 and abuts against the second mold 20 to drive the second mold 20 to move toward the first mold 10.

[0081] In this embodiment, pressure is applied by the stamping structure 80 to ensure a tight fit between the first clamping portion 31 and the second clamping portion 32, thereby improving the clarity of the clamping marks on the cardboard. In this embodiment, the stamping structure 80 can be a floating block and a spring guide assembly. One end of the spring guide assembly is connected to the floating block, and the other end is connected to the first mold 10. The spring guide assembly extends and retracts when the mold is opened or closed, thereby causing the floating block to float up and down, driving the second mold 20 to move towards the first mold 10. One or more stamping structures 80 can be provided; this is not limited here.

[0082] Furthermore, refer to Figure 1 , Figure 4 In one embodiment of this utility model, the stamping structure 80 includes:

[0083] Support frame 81; located in the first mold 10;

[0084] The stamping plate 82 is rotatably connected to the support frame 81;

[0085] Elastic element 83, one end of which is connected to stamping plate 82, and the other end of which is connected to first mold 10; and

[0086] The stamping column 84 is located on the side of the stamping plate 82 facing the second mold 20.

[0087] In this embodiment, the stamping structure 80 may further include a support frame 81, a stamping plate 82, an elastic element 83, and a stamping column 84. In this embodiment, the elastic element 83 may be a spring. The stamping plate 82 and the support frame 81 can be rotatably connected via a pivot. When the second mold 20 is placed on the first mold 10, a force is applied to one end of the stamping plate 82, causing the stamping plate 82 to rotate around the pivot, thereby causing the end face of the stamping column 84 at the other end to abut against the second mold 20. Continuing to apply force causes the second mold 20 to move towards the first mold 10, thereby squeezing the cardboard in the middle and creating indentations on the surface of the cardboard along the edge of the indentation structure 30. When the external force disappears, the stamping column 84 returns to its initial position under the elastic force of the spring, thus achieving the separation of the second mold 20 from the first mold 10. Of course, to improve the service life of the mold, a reinforcing shim can be provided at the end of the stamping column 84 facing the second mold 20 to reduce local pressure on the second mold 20.

[0088] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
