The direction of the thread in the first threaded through hole is opposite to the direction of the thread in the second threaded through hole. The threaded through hole matches the external thread of the corresponding threaded rod 52, and the threaded rod 52 is arranged in the threaded through hole.

[0044] Among them, the third driving member 51 is used to drive the threaded rod 52 to rotate forward, so that the two fixed structures 53 move toward each other due to the cooperation of the threaded screw; the third driving member 51 is also used to drive the threaded rod 52 to rotate reversely, so that the two fixed structures 53 move away from each other due to the cooperation of the threaded screw.

[0045] It can be understood that the third driving member 51 is a device for pushing the fixing structure 53 to move through the threaded rod 52; for example, the third driving member 51 can be a rotary motor or a hydraulic motor, etc. The fixing structure 53 is a structure for fixing the cardboard in the cutting space 101; for example, the fixing structure 53 can be two upper and lower movable rods or two fixed clamps.

[0046] In this configuration, the third driving member 51 pushes the fixing structure 53 to move through the threaded rod 52 , so that the fixing structure 53 can adapt to paperboards of different sizes by adjusting the distance between the two fixing structures 53 .

[0047] For example, see Figures 3 to 5 The fixed structure 53 includes two moving parts 54, two active parts 55 and at least four springs 56. Wherein: The moving member 54 has a threaded through hole. The moving member 54 is located in the fixed adjustment slot 103 . The moving member 54 has a first space 540 .

[0048] The movable member 55 is partially located in the cutting space 101, and one end of the movable member 55 extends into the first space 540 of one of the movable members 54, and the other end of the movable member 55 extends into the first space 540 of the other movable member 54; the two movable members 55 are arranged relative to each other, and a fixed space 550 is formed between the two movable members 55, and the cardboard part is located in the fixed space 550; the movable member 55 includes a flattening portion 551 and a fixed portion 552, both ends of the flattening portion 551 and the fixed portion 552 are arranged in the first space 540, and the remaining parts of the flattening portion 551 and the fixed portion 552 are located in the cutting space 101; the height of the flattening portion 551 is slightly higher than that of the fixed portion 552, the bottom wall of the flattening portion 551 facing away from the cardboard and the bottom wall of the fixed portion 552 facing away from the cardboard are located on the same plane, and the side wall of the fixed portion 552 is connected to the side wall of the flattening portion 551.

[0049] Two of the springs 56 are located in the first space 540 of one of the moving parts 54; one end of one of the springs 56 is connected to the inner side wall of one of the first spaces 540 facing away from the paperboard, and the other end is connected to the bottom wall of the moving part 55 facing away from the paperboard; one end of the other spring 56 is connected to the inner side wall of the other first space 540 facing away from the paperboard, and the other end is connected to the bottom wall of the moving part 55 facing away from the paperboard.

[0050] Among them, the third driving member 51 is used to drive the two moving members 54 on the threaded rod 52 to move in opposite directions through the threaded rod 52, so that the movable member 55 can remove the wrinkles of the cardboard by moving, and when the surface of the movable member 55 close to the cardboard is separated from the cardboard, the movable member 55 is pushed toward the cardboard under the action of the restoring force of the spring 56, so that the surface of the movable member 55 away from the cardboard contacts the cardboard, thereby fixing the cardboard.

[0051] It can be understood that the moving member 54 is a member used to drive the movable member 55 to move; the moving member 54 can be a block with a threaded hole or a shell with a threaded hole. The movable member 55 is a member used to fix and flatten the paper; the movable member 55 can be a straight rod with a fixed portion 552 and a flattening portion 551 or a round rod with a fixed portion 552 and a flattening portion 551. The spring 56 is a member used to push the movable member 55 to move toward the paper. The fixed portion 552 is a member used to fix the paperboard; for example, the fixed portion 552 can be a rectangular parallelepiped rod or a rectangular parallelepiped shell, etc. The flattening portion 551 is a device used to flatten the paperboard; for example, the flattening portion 551 can be a rectangular parallelepiped rod or a rectangular parallelepiped shell, etc.

[0052] With such a configuration, the third driving member 51 drives the movable member 55 to move through the moving member 54. When the paperboard contacts the flattening portion 551, the flattening portion 551 flattens the surface of the paperboard, thereby making the cutting process smoother, thereby reducing the probability of bad cutting and protecting the cutting tool 32. When the flattening portion 551 is separated from the paperboard, the spring 56 pushes the movable member 55 to move toward the paperboard, so that the fixing portion 552 contacts the paperboard, so that the paperboard can be suspended and fixed in the cutting space 101, thereby facilitating subsequent cutting and avoiding damage to the top of the cutting tool 32 during cutting.

[0053] In some embodiments, see Figure 4 The area of ​​the side of the flattening portion 551 facing the paperboard is smaller than the area of ​​the side of the fixing portion 552 facing the paperboard, and the roughness of the side of the flattening portion 551 facing the paperboard is smaller than the roughness of the side of the fixing portion 552 facing the paperboard.

[0054] In this configuration, the contact area between the fixing portion 552 and the paperboard is increased and the roughness of the fixing portion 552 is increased to increase the friction between the fixing portion 552 and the paperboard, so that the fixing portion 552 can more stably fix the paperboard in the cutting space 101; the contact area between the flattening portion 551 and the paperboard is reduced and the roughness of the flattening portion 551 is reduced to reduce the friction between the flattening portion 551 and the paperboard, so that the flattening portion 551 can flatten the paperboard, thereby making it easier for the paperboard cutting portion 30 to cut the paperboard.

[0055] Optionally, in some embodiments, see Figures 1 to 5 The cardboard cutting unit 30 includes a cutting mounting member 31 and a cutting tool 32. Wherein: The cutting mounting member 31 is located in the cutting space 101 and is connected to the control unit 20. The cutting mounting member 31 has a tool mounting hole 310, and the opening of the tool mounting hole 310 faces the bottom wall of the cutting space 101. The cooling unit 40 is arranged on the bottom wall of the cutting mounting member 31 facing the cardboard.

[0056] The cutting tool 32 is disposed in the tool mounting hole 310 , and the cutting end of the cutting tool 32 faces the bottom wall of the cutting space 101 .

[0057] It can be understood that the cutting installation member 31 is a member used to constrain the knife to slide on the control member 22; for example, the cutting installation member 31 can be a bolt structure or a locking structure, etc. The cutting knife 32 is a member used to cut the cardboard.

[0058] In this arrangement, by fixing the cutting mounting member 31 on the power output end of the second driving member 23, the cutting tool 32 can move following the power output end of the second driving member 23; compared with directly fixing the cutting tool 32 to the power output end of the second driving member 23, the above scheme can avoid the cutting tool 32 from damaging the power output end of the second driving member 23 when performing a cutting operation.

[0059] Optionally, see Figures 1 to 5 The cutting mounting member 31 also has two cooling mounting holes, which are respectively located on both sides of the tool mounting hole 310. The cooling unit 40 includes a first cooling fan 41 and a second cooling fan 42. The first cooling fan 41 is disposed in one of the cooling installation holes, and the air outlet of the first cooling fan 41 faces the bottom wall of the cutting space 101; and The second cooling fan 42 is disposed in the other cooling installation hole, and an air outlet of the second cooling fan 42 faces the bottom wall of the cutting space 101 .

[0060] It can be understood that the first cooling fan 41 is a device for helping to lower the cutting tool 32; for example, the first cooling fan 41 can be a small centrifugal fan or a small axial flow fan, etc. The second cooling fan 42 is a device for helping to lower the cutting tool; for example, the second cooling fan 42 can be a small household hair dryer or a small industrial hair dryer, etc.

[0061] In this way, by arranging the first cooling fan 41 and the second cooling fan 42 on both sides of the cutting tool 32, gas flow is generated on both sides of the cutting tool 32, thereby accelerating the heat dissipation speed of the tool; compared with the solution of adding a water adding device on the cutting tool 32, the above solution can accelerate the heat dissipation speed of the tool while avoiding damage to the cardboard.

[0062] In some embodiments, see Figures 1 to 5 The cardboard is divided into a target cardboard and excess cardboard. The cardboard fixing part 50 suspends the cardboard part by fixing the two ends of the cardboard. The second cooling fan 42 is close to the target cardboard, and the target cardboard is pushed away from the excess cardboard by the second cooling fan 42.

[0063] In this way, the cardboard is partially suspended in the cutting space 101 through the cardboard fixing part 50, so that the second cooling fan 42 can separate the target cardboard from the excess cardboard; compared with directly placing the cardboard on the inner bottom wall of the cutting space 101, the above scheme can promptly separate the target cardboard from the excess cardboard during the cutting process.

[0064] In some embodiments, see Figure 1The control unit 20 also includes a tool steering member 24, which is located in the moving groove 220, and one end of the tool steering member 24 is arranged on the power output end of the second driving member 23, and the other end of the tool steering member 24 is connected to the cutting mounting member 31.

[0065] It can be understood that the tool steering member 24 is a device for controlling the cutting direction of the cutting tool 32; for example, the tool steering member 24 can be a device in which a rotating shaft cooperates with a rotating motor, and the cardboard cutting part 30 is connected to the control part 20 through the rotating shaft, and the rotating shaft is connected to the power output end of the rotating motor, so that the rotating motor can control the cutting direction of the cutting tool 32 through the rotating shaft.

[0066] In this configuration, a tool steering member 24 is provided between the control member 22 and the paperboard cutting unit 30, so that when the paperboard cutting unit 30 performs a cutting operation, the cutting direction of the cutting tool 32 can be changed. Compared with cutting in different directions by using multiple cutting tools 32, the above solution can perform cutting in different directions by using one cutting tool 32, thereby simplifying the cutting process and reducing the manufacturing cost of the cutting device.

[0067] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
