[0034] like Figures 1 to 2 As shown, it is a paper box punching machine 100 of this utility model, used for punching holes in paper boxes.

[0035] like Figures 1 to 2 As shown, the cardboard box punching machine 100 includes: a fixed base 10, a knife holder 20, a punching mechanism 30, a pre-pressing component 40, and a driving mechanism 50. The knife holder 20 is mounted on the fixed base 10 and has a knife hole 221. The punching mechanism 30 includes a guide seat 31 and a knife head 32. The guide seat 31 is slidably connected to the knife holder 20, and the knife head 32 is connected to the guide seat 31 and positioned on the side of the guide seat 31 near the knife hole 221. The pre-pressing component 40 includes a connecting part 41, an elastic part 42, and a contact part 43. The connecting part 41 is connected to the guide seat 31, the elastic part 42 surrounds the knife head 32, and the contact part 43 is connected to the end of the elastic part 42 near the knife hole 221 and located between the knife head 32 and the knife hole 221. The contact part 43 has a clearance space 431 for the knife head 32 to pass through. The driving mechanism 50 drives the knife head 32 to insert into the knife hole 221. 1. The cutter head 32 is separated from the cutter hole 221. The guide seat 31 of the punching mechanism 30 is slidably connected to the cutter holder 20. The cutter head 32 is set on the side of the guide seat 31 near the cutter hole 221. The contact part 43 of the pre-pressing member 40 is located between the cutter head 32 and the cutter hole 221. The contact part 43 is provided with a clearance space 431 for the cutter head 32 to pass through. The driving mechanism 50 drives the cutter head 32 to insert into the cutter hole 221 or to separate the cutter head 32 from the cutter hole 221. By setting the pre-pressing member 40, before the cutter head 32 punches, the contact part 43 of the pre-pressing member 40 first contacts the paper box. The elastic part 42 generates elastic deformation to pre-press and fix the paper box, so that the paper box is positioned more accurately during the punching process. This effectively avoids the problem of punching position deviation caused by inaccurate positioning of the paper box, thereby increasing the punching accuracy of the paper box and improving the production yield of the paper box.

[0036] The following text, combined with Figures 1 to 4 The above-mentioned cardboard box punching machine 100 will be further explained.

[0037] To ensure the punching quality of the punching machine, such as Figures 2 to 3As shown, the punching mechanism 30 also includes an elastic element 33. The guide seat 31 is slidably connected to the cutter head 32. The elastic element 33 is used to provide elastic force for the cutter head 32 to approach the cutter hole 221. The elastic element 33 is a spring. By providing elastic force for the cutter head 32 to approach the cutter hole 221 through the elastic element 33, the cutter head 32 can be prevented from quickly separating from the cardboard box after punching, thereby preventing damage to the cardboard box and achieving the purpose of improving the punching quality of the punching machine.

[0038] Furthermore, in order to improve punching accuracy and punching quality, such as Figures 2 to 3 As shown, the guide seat 31 includes a seat body 311 and a limiting plate 312. The seat body 311 is provided with a sliding hole 313. The limiting plate 312 is connected to the seat body 311 and is provided with a through hole 314 communicating with the sliding hole 313. The cutter head 32 is slidably connected to the sliding hole 313 and movably passes through the through hole 314. The sliding hole 313 provides a stable sliding guide for the cutter head 32, further restricting the movement trajectory of the cutter head 32, ensuring the stability and accuracy of the cutter head 32 in the punching process, and achieving the purpose of improving punching accuracy and punching quality.

[0039] For example, to improve punching accuracy, such as Figure 3 As shown, the cutter head 32 includes a slide 321 and a cutter 322. The slide 321 is slidably connected to the slide hole 313. The cutter 322 is coplanar with the slide 321 and protrudes from one side of the slide 321. The cutter 322 movably passes through the through hole 314. The design of the cutter 322 protruding from the slide 321 can effectively limit the cutting depth of the cutter head 32, so that the cutter 322 can better cooperate with the cutter hole 221, thereby improving the punching accuracy.

[0040] like Figure 3 As shown, the elastic element 33 is disposed in the sliding hole 313 and abuts against the cutter head 32. The slide 321 of the cutter head 32 is provided with a receiving hole 323 for accommodating part of the elastic element 33. The receiving hole 323 can reasonably restrict the position of the elastic element 33, making the elastic force of the elastic element 33 more direct and effective, thereby ensuring the stability and reliability of the cutter head 32 during the movement process, and achieving the purpose of further improving the service life of the cutter head 32 and the working efficiency of the punching machine.

[0041] like Figure 4As shown, the tool holder 20 includes a guide portion 21 and a punched portion 22. The guide portion 21 is mounted on the fixed base 10 and slidably connected to the guide seat 31. The punched portion 22 has a tool hole 221. The guide portion 21 includes a body 211 and a slide rail 212. The slide rail 212 is coplanar with the body 211 and protrudes from one side of the body 211. The seat 311 of the guide seat 31 has a groove that slidably connects with the slide rail 212. Furthermore, the slide rail 212 has a trapezoidal cross-section and gradually tapers towards the side closer to the body 211. The cooperation between the slide rail 212 and the groove... The guide seat 31 provides a stable sliding guide, ensuring its accuracy and stability during movement. This makes the fit between the cutter head 32 and the cutter hole 221 of the guide seat 31 more accurate, thereby improving the punching quality of the punching machine. The trapezoidal slide rail 212 structure not only prevents the guide seat 31 from detaching from the cutter holder 20, but also improves the displacement accuracy and stability of the slide rail 212 and the slide groove, reduces the shaking between the slide rail 212 and the slide groove, and further ensures the accuracy and reliability of the guide seat 31 during movement, thus achieving the goal of improving the punching accuracy of the punching machine.

[0042] To improve the placement accuracy of cardboard boxes, such as Figure 4 As shown, the knife holder 20 also includes a positioning rod 23, which is connected to the side of the punching part 22 with the knife hole 221. The cardboard box is provided with a positioning hole that cooperates with the positioning rod 23. Through the cooperation between the positioning hole of the cardboard box and the positioning rod 23 of the knife holder 20, the placement position of the cardboard box is restricted, so as to improve the placement accuracy of the cardboard box.

[0043] During punching, because the contact part 43 is tightly attached to the cardboard box, the contracted elastic part 42 easily squeezes the air in the pre-compression part 40. The compressed air is difficult to expel from the pre-compression part 40 and can easily push the cardboard box away from the contact part 43 through the clearance space 431, resulting in the cardboard box shifting relative to the contact part 43. This results in an unsatisfactory pre-compression effect of the pre-compression part 40.

[0044] To prevent compressed air from leaking between the contact part 43 and the cardboard box, such as Figure 3 As shown, the pre-compression component 40 is also provided with a vent hole 421. The vent hole 421 is provided on the elastic part 42. When the elastic part 42 undergoes elastic deformation, the vent hole 421 can timely discharge the air inside the pre-compression component 40, preventing the compressed air from pushing the cardboard box away from the contact part 43 through the clearance space 431. This ensures that the contact part 43 can always maintain a tight fit with the cardboard box during the punching process, thereby preventing the cardboard box from shifting relative to the contact part 43 and achieving the purpose of improving the pre-compression effect of the pre-compression component 40.

[0045] like Figure 3As shown, the elastic part 42 is corrugated. The corrugated elastic part 42 has better elasticity and flexibility, which can prevent the elastic part 42 from breaking after repeated expansion and contraction, thereby increasing the service life of the elastic part 42 and achieving the purpose of improving the overall service life of the preloaded part 40.

[0046] like Figures 1 to 2 As shown, the drive mechanism 50 includes a drive component 51, a telescopic rod 52, a swing arm 53, a rotating seat 54, and a joint bearing 55. The drive component 51 is a cylinder and is connected to the fixed seat 10. There are two telescopic rods 52, which are slidably connected to both ends of the swing arm 53. One telescopic rod 52 is movably connected to the drive component 51, and the other telescopic rod 52 is movably connected to the joint bearing 55. The swing arm 53 is rotatably connected to the rotating seat 54, which is located between the two telescopic rods 52 and is mounted on the fixed seat 10. The joint bearing 55 is connected to the tool holder 20.

[0047] When using the cardboard box punching machine 100 provided in this application: the cardboard box is placed on the punching part 22 of the knife holder 20. The cardboard box is positioned by the cooperation of the positioning hole of the cardboard box and the positioning rod 23 on the punching part 22. The drive mechanism 50 is started, and the drive mechanism 50 drives the guide seat 31 to slide along the knife holder 20. The contact part 43 of the pre-pressing part 40 first contacts the cardboard box, and the elastic part 42 undergoes elastic deformation to pre-press and fix the cardboard box. As the guide seat 31 continues to move, the cutter head 32 gradually approaches the knife hole 221 under the elastic force of the elastic part 33 and the action of the drive mechanism 50, and finally passes through the cardboard box and inserts into the knife hole 221 to complete the punching operation of the cardboard box. After the punching is completed, the drive mechanism 50 drives the cutter head 32 to separate from the knife hole 221. The cutter head 32 is reset under the action of the elastic part 33 and waits for the next punching operation.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
