Description
Technical Field
[0001] This utility model relates to the field of cardboard production, and in particular to cardboard punching equipment. Background Technology
[0002] A cardboard punching machine is a specialized mechanical device used to punch holes in cardboard materials. Its working principle primarily involves using mechanical power to drive the punching component, applying pressure to the cardboard to create holes. This is similar to piercing cardboard with a sharp tool, except that this type of equipment ensures precision, speed, and consistency in punching. For example, some simple manual cardboard punching machines utilize the lever principle; when the handle is pressed, the punching needle penetrates the cardboard under pressure. More automated machines, on the other hand, use a motor to drive the punching head, punching holes according to preset programs and parameters.
[0003] In traditional cardboard punching processes, the lack of effective limiting and positioning mechanisms makes it easy for the cardboard to shift during punching, resulting in inaccurate punching positions and directly affecting the quality of the final product. Secondly, manual adjustments or the low level of automation in traditional mechanical devices not only limit production efficiency but also make it difficult to meet the needs of large-scale production. Furthermore, changing molds for different shapes and sizes of punching requirements is often time-consuming and labor-intensive, reducing the flexibility of the production line and further affecting the smoothness and responsiveness of production. At the same time, during the punching process, uneven pressure or unreasonable structural design may cause the mold to shift or detach, seriously affecting the quality and consistency of punching and reducing the production efficiency of cardboard punching.
[0004] Therefore, it is necessary to provide a new cardboard punching device to solve the above-mentioned technical problems. Utility Model Content

[0029] In the specific implementation process, such as Figures 1-7As shown, the cardboard punching device provided by this utility model includes a base 1, a punching component 2, a transport component 3, a punching mold 4, and a limiting component 5. The bottom end of the punching component 2 is detachably connected to the top end of the transport component 3 by multiple bolts 24.

The punching mold 4 is located at the top of the base 1 and inside the punching component 2.
[0030] The punching assembly 2 includes a pressing member 21, a pressing component 23, and two fixing members 22.

The punching mold 4 is engaged and located inside the model groove 234.
[0032] It should be noted that when the lower pressure body presses down to punch holes in the cardboard, the surface inside the lower pressure body will press the upper mold 41 to move towards the lower mold 42, so that when the upper mold 41 and the lower mold 42 are pressing and punching, the upper mold 41 will not detach from the mold groove 234 opened inside the lower pressure plate 231, and the upper mold 41 and the lower mold 42 will not squeeze and tangentially press the cardboard to form a hole.
[0033] The base 1 has a placement platform 11 at the top, and the top surface of the placement platform 11 has a placement groove 12 for the installation of the drilling mold 4. The drilling mold 4 is engaged and located inside the placement groove 12.
[0034] It should be noted that the placement slot 12 is equipped with multiple placement calipers to facilitate adjustable engagement and placement with the lower mold 42.
[0035] The base 1 has a rotating groove 13 for the limiting component 5 to rotate inside one end near the placement platform 11. The base 1 has a movable groove 14 for the linkage component 6 to move on one side, and the movable groove 14 is connected to the rotating groove 13. One end of the linkage component 6 passes through the movable groove 14 and extends into the rotating groove 13 and fits against one end of the limiting component 5.
[0036] In one specific embodiment, the vertical cross-sectional area of the movable groove 14 is smaller than that of the rotating groove 13.
[0037] The punching mold 4 includes an upper mold 41 and a lower mold 42. The upper mold 41 is engaged inside the mold groove 234, and the lower mold 42 is engaged inside the placement groove 12.
[0038] It should be noted that the upper mold 41 and the lower mold 42 can be replaced according to the shape of the hole to be drilled.
[0039] The transport component 3 includes two tracks 31, two rollers 32 and two protective plates 33. The two rollers 32 are located between the two protective plates 33, and the two ends of the two rollers 32 are rotatably connected to the surfaces of the two protective plates 33. The two tracks 31 are both fitted on the outer surfaces of the two rollers 32, and the bottom ends of the two rollers 32 are fixedly connected to the top of the base 1.
[0040] One end of one of the two rollers 32 passes through one side of the inner surface of the base 1 and extends to the outside of the base 1. A motor 34 is provided at the end of the roller 32 extending to the outside of the base 1. The output end of the motor 34 is fixedly connected to the end of the roller 32 extending to the outside of the base 1.
[0041] The limiting component 5 includes a rotating shaft 51 and a blocking component 52. The two ends of the rotating shaft 51 are fixedly connected to the inner sidewall of the rotating groove 13, and the blocking component 52 is rotatably sleeved on the outer surface of the rotating shaft 51. A weight block 53 is fixedly provided at one end of the blocking component 52 located on the rotating shaft 51.
[0042] The linkage component 6 includes a linkage rod 61 and a toggle rod 62. One end of the linkage rod 61 is rotatably sleeved on one side of the pressing member 21, and the other end of the linkage rod 61 is fixedly connected to one end of the toggle rod 62. The toggle rod 62 is movably located inside the rotating groove 13 and extends into the movable groove 14. The outer surface of the toggle rod 62 is in contact with the bottom surface of the end of the blocking member 52 where the weight block 53 is located.
[0043] In one specific embodiment, when the pressing body presses down to cut and punch holes in the cardboard, the linkage rod 61 drives the actuating rod 62 to move along the inner surface of the movable groove 14, so that the actuating rod 62 is located at the bottom of the blocking member 52. After the pressing body finishes the punching operation, the linkage rod 61 will drive the actuating rod 62 to move upward along the inner surface of the movable groove 14, so that the blocking member 52 will rotate during the upward process. At this time, the cooperating transport component 3 loses its ability to limit the punched cardboard until the actuating rod 62 loses contact with the surface of the blocking member 52. At this time, the blocking member 52 will be reset by the gravity of the weight block 53 to limit and block the next cardboard.
[0044] The working principle provided by this utility model is as follows:
[0045] When punching the cardboard, the cardboard is placed on the two tracks 31 of the transport assembly 3. The motor 34 drives the roller 32 to rotate, smoothly transporting the cardboard. The limiting assembly 5 then functions to limit and block the cardboard. When the cardboard reaches the correct position, the linkage component 6 adjusts its position according to the action of the pressing component 21. The actuating rod 62 moves along the movable groove 14, causing the blocking component 52 to rotate and temporarily move away from the cardboard, ensuring that the cardboard can be accurately positioned. Then, during the punching operation, when the pressing component 21 moves downward under force, it drives the lower pressure plate 231 in the pressing component 23 to slide down along the guide post 232, while compressing the spring 233. The upper mold 41 moves downward accordingly and closes with the lower fixed part. The upper mold 42 is precisely matched to complete the pressure punching process of the cardboard. Due to the design of the mold groove 234 inside the lower pressure plate 231, the upper mold 41 remains stable throughout the process, avoiding the risk of detachment or displacement. After punching is completed, as the lower pressure component 21 rises, the spring 233 pushes the lower pressure plate 231 back to the initial position. At the same time, the linkage component 6 drives the lever 62 to move upward, so that the blocking component 52 returns to its original position due to the action of the weight block 53, preparing for the next cycle. The whole process can be carried out continuously, ensuring that the punching task of a large number of cardboards is completed efficiently and accurately, which greatly improves production efficiency and punching accuracy. It is very suitable for production environments that require a large number of cardboard punching processes.
