Technical Field

[0001] This utility model relates to the technical field of stationery processing, specifically to a hole-opening device for stationery processing. Background Technology

[0002] The hole-making process in stationery manufacturing involves creating holes in stationery products using various tools and equipment. Common hole-making methods include using hole punches, drilling machines, CNC machine tools, laser cutting machines, punch presses, and electrical discharge machining. These methods are suitable for hole-making tasks with different materials and precision requirements, such as paper, metal, and plastic.

[0003] In stationery manufacturing, when making holes in paper notebooks and other stationery, laser cutting or drilling is generally not used to ensure that the paper material is not damaged. Instead, a cylindrical cutter is mainly used. During the cutting process, the cut paper will enter the cylindrical cutter and is not easy to remove, which affects the efficiency of the cutting process. Utility Model Content

[0009] As a preferred embodiment of this utility model, the drive motor faces downward and a transmission cylinder is installed at its output end. A transmission disc is provided at the lower end of the transmission cylinder. The transmission cylinder has multiple transmission holes arranged in a ring at equal intervals. Multiple transmission pins corresponding to and movably connected to the transmission holes are installed at the upper end of the transmission disc.

[0010] In a preferred embodiment of this utility model, the push rod is fixed at the center of the bottom of the transmission cylinder, the annular cylinder cutter is fixed at the center of the bottom of the transmission disc and corresponds to the transmission cylinder, and the push rod passes through the transmission disc and extends into the annular cylinder cutter and is movably connected to the annular cylinder cutter.

[0011] As a preferred technical solution of this utility model, the lifting drive assembly includes a drive cylinder fixed on the upper end of the mounting base facing upward. A transmission plate is installed at the output end of the drive cylinder. A transmission column is symmetrically installed at the bottom of the transmission plate, penetrating the mounting base and movably connected to the mounting base. A transmission clamp is installed at the bottom of the transmission column respectively. The transmission disc is rotatably connected between the transmission clamps.

[0012] As a preferred embodiment of this utility model, the inner wall of the transmission clamp is arc-shaped and rotatably connected to the transmission disk. The inner wall of the transmission clamp is provided with a rotating groove, and a rotating ring is installed on the outer wall of the transmission disk.

Specifically, the position of the push rod 422 is fixed and will not rise or fall. When the annular cylinder knife 44 is raised, the push rod 422 will push out the waste paper inside the annular cylinder knife 44.

[0030] Please refer to the appendix. Figure 2 Appendix Figure 3 The lifting drive assembly 3 includes a drive cylinder 31 fixed on the upper end of the mounting base 2 with its upper end facing upward. A transmission plate 32 is installed at the output end of the drive cylinder 31.

[0032] Example 2

[0033] Based on the above embodiment one, please refer to the appendix. Figure 2 Appendix Figure 3 Appendix Figure 5 A pressure plate 35 is installed at the bottom of the transmission disc 43 via a connecting rod 342. A pressure platform 351 is installed at the bottom of the pressure plate 35. A through hole 352 is provided at the center of the pressure platform 351, which is movably connected to the annular cylindrical cutter 44. The pressure platform 351 corresponds to and cooperates with the placement platform 11.

[0034] In this embodiment, after the drive cylinder 31 drives the annular tube knife 44 to descend and make a hole, the pressure table 351 can press and flatten the stacked paper to prevent the paper from shifting.

[0035] Working principle and usage process of this utility model:

[0036] Place the notebook or other paper stationery to be punched on the placement platform 11, align the desired punching position with the perforation 352, and then activate the drive cylinder 31 and drive motor 41. The drive cylinder 31 drives the transmission plate 32 to move downwards, and the transmission plate 32 drives the transmission clamp 34 to move downwards via the transmission column 33. The transmission clamp 34 drives the transmission disc 43 to move downwards. At the same time, the drive motor 41 drives the transmission cylinder 42 to rotate, and the transmission cylinder 42 drives the transmission disc 43 to rotate via the transmission pin 432 and the transmission hole 421. The transmission disc 43 rotates between the transmission clamps 34 via the rotating ring 431. Meanwhile, the transmission clamps 34 continue to rotate. The transmission disc 43 moves downward, and the annular tube knife 44 at the lower end of the transmission disc 43 moves downward and rotates under the drive of the transmission disc 43. The annular tube knife 44 makes holes in the paper stationery. The waste paper generated during the hole-making process is cut off by the annular tube knife 44 and accumulates inside the annular tube knife 44. After the hole-making is completed, the drive motor 41 is turned off and the drive cylinder 31 is controlled to reset. At this time, the transmission disc 43 moves upward and drives the annular tube knife 44 to move upward. As the annular tube knife 44 moves upward, the push rod 422 at the bottom of the transmission cylinder 42 will push the waste paper inside the annular tube knife 44 out of the annular tube knife 44, completing the hole-making operation.
