The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 3 As shown, the utility model provides a hole-making device for carton production, comprising: a workbench 1, a rotating shaft 2, a plurality of carrying arms 3 and a hole-making drill bit 5.

[0030] The bottom of the workbench 1 is provided with supporting legs, and a supporting frame 11 is vertically provided on the workbench 1 .

[0031] The rotating shaft 2 is arranged vertically and is rotatably mounted on the workbench 1. The workbench 1 is equipped with a driving mechanism for driving the rotating shaft 2.

[0032] The drive mechanism includes a driven gear 61, a drive motor 62, and a transmission gear 63. Specifically, the driven gear 61 is coaxially connected to the rotating shaft 2. The drive motor 62 is mounted on the workbench 1, with its output shaft arranged vertically. The transmission gear 63 is coaxially connected to the output shaft of the drive motor 62 and meshes with the driven gear 61. When the drive motor 62 is activated, the driven gear 61 and the transmission gear 63 drive the rotating shaft 2 to rotate.

[0033] The side of the rotating shaft 2 is connected to a plurality of supporting arms 3, and the plurality of supporting arms 3 are arranged at intervals along the circumference of the rotating shaft 2. Figure 3 As shown, in this embodiment, three supporting arms 3 are connected to the side of the rotating shaft 2. The three supporting arms 3 are arranged at equal angles along the circumference of the rotating shaft 2.

[0034] The end of the support arm 3, away from the rotating shaft 2, is formed with a retaining slot a for inserting the carton 4. A pressure plate 31 is mounted in a slidable manner within the retaining slot a, pressing against the carton 4. The support arm 3 is equipped with a drive element for actuating the pressure plate 31. The support arm 3 is provided with a vertically arranged positioning hole b, and the pressure plate 31 is formed with a through hole c aligned with the positioning hole b.

[0035] Specifically, a stopper hole, connected to the stopper slot a, is defined in the middle of the upper portion of the support arm 3. The driving element is a pull rod 32, which is movably inserted into the stopper hole. The lower end of the pull rod 32 is connected to the pressure plate 31. A first push spring 71 is sleeved around the pull rod 32, with its ends pressing against the pressure plate 31 and the top wall of the stopper slot a, respectively.

[0036] After the side of the carton 4 is inserted into the limiting groove a, the pressure plate 31 is pressed against the carton 4, and the elastic force of the first push spring 71 acts on the pressure plate 31, thereby increasing the pressure of the pressure plate 31 on the carton 4 and maintaining the stability of the carton 4.

[0037] Preferably, a plurality of guide holes connected to the limiting slot a are formed on the upper side of the carrying arm 3. A plurality of guide rods 33 are connected to the top of the pressing plate 31, and the guide rods 33 are movably inserted into the guide holes.

[0038] The guide rod 33 is sleeved with a second push spring 72 , and two ends of the second push spring 72 are pressed against the pressure plate 31 and the top groove wall of the limiting groove a respectively.

[0039] By installing multiple guide rods 33, the stability of the pressure plate 31 is improved. By installing a second push spring 72 on the guide rod 33, the elastic force of the push spring 72 acts on the pressure plate 31, thereby further increasing the pressure of the pressure plate 31 on the carton 4, making the carton 4 more stable.

[0040] As a preferred embodiment, the lower end of the pull rod 32 is rotatably connected to the pressure plate 31. A limiting ridge 321 is formed on the side of the pull rod 32, and the two ends of the first push spring 71 respectively press against the limiting ridge 321 of the pull rod 32 and the top wall of the limiting slot a.

[0041] A bearing plate is vertically provided on the top groove wall of the limiting through groove a, and the lower part of the bearing plate extends toward the pull rod 32 to form a supporting flange 8, which is arranged above the limiting ridge 321.

[0042] See Figure 2 As shown, after pulling the pull rod 32 upward and rotating it, the supporting flange 8 is supported on the limiting ridge 321, so that the pressure plate 31 is lifted and locked to the top groove wall of the limiting groove a, thereby releasing the lock of the pressure plate 31 on the carton 4, making it easier for the operator to complete the loading and unloading of the carton 4.

[0043] The drilling head 5 is movably mounted on the support frame 11 . The drilling head 5 is aligned with a positioning through hole b of the carrying arm 3 .

[0044] Specifically, an electric push rod 51 is mounted on the support frame 11. The electric push rod 51 is vertically arranged. A rotary motor 52 is mounted at the lower end of the electric push rod 51. The drive shaft of the rotary motor 52 is vertically arranged. The drilling bit 5 is coaxially connected to the drive shaft of the rotary motor 52.

[0045] As a preferred embodiment, a chip box 9 is detachably mounted on the bottom of the carrying arm 3 , and an opening is formed on the top of the chip box 9 , which is aligned with the positioning through hole b of the carrying arm 3 .

[0046] Specifically, the bottom of the support arm 3 is formed with an assembly groove, which is connected to the positioning perforation b. The sidewalls of the assembly groove are annular and have internal threads. The chip box 9 is cylindrical and has external threads formed on the outside. The chip box 9 screws into the internal threads of the assembly groove. When the drilling drill 5 drills the carton 4, debris is generated. The chip box 9 is used to accommodate this debris, thereby keeping the interior of the carton 4 clean and tidy. The chip box 9 is easy to assemble and disassemble, making it easy to regularly clean the debris in the chip box 9.

[0047] The working principle and use process of the hole-opening device for carton production of this utility model:

[0048] S1 . The driving motor 62 drives the rotating shaft 2 to rotate, so that the three supporting arms 3 are sequentially moved to the processing station (below the drilling bit 5 ) at preset time intervals.

[0049] S2. After the carrying arm 3 moves to the processing station, the rotating motor 52 drives the hole-opening drill bit 5 to rotate, and the electric push rod 51 drives the hole-opening drill bit 5 to descend. The hole-opening drill bit 5 penetrates the positioning hole b of the carrying arm 3 to complete the hole-opening of the carton 4. The debris generated by the hole-opening is contained in the chip collection box 9.

[0050] S3. After the hole drilling is completed, the carrying arm 3 moves to the blanking station. The next carrying arm moves to the processing station, and the drilling drill 5 performs hole drilling on the carton of the next carrying arm.

[0051] S4. The operator at the unloading station pulls up and rotates the pull rod 32 so that the supporting flange 8 is supported on the limiting rib 321 of the pull rod 32, and the pressing plate 31 is lifted and locked to the top wall of the limiting slot a. The carton 4 is then taken out, completing the unloading of the carton 4. After the carton 4 is unloaded, the side of the next carton to be processed is inserted between the pressing plate 31 and the bottom wall of the limiting slot a, and the predetermined opening point of the carton is adjusted to the positioning perforation b. The pull rod 32 is rotated so that the limiting rib 321 is separated from the supporting flange 8, and the first push spring 71 and the second push spring 72 push the pressing plate 31 so that the pressing plate 31 is pressed against the side of the carton, thereby locking the carton and completing the loading of the next carton to be processed.

[0052] S5. Repeat steps S2 to S4 to complete the hole-punching operation of the batch of cartons.

[0053] This new carton drilling device features multiple supporting arms connected to the sides of a rotating shaft, and positioning holes formed on a supporting plate. When drilling a carton, the sides of the carton are inserted into the limiting slots of the supporting arms, and a pressure plate is used to press and lock the carton. This ensures that the carton remains stable when the drilling bit is applied, preventing it from sinking or deforming, thereby improving the quality of the hole drilled.

[0054] The positioning perforations on the carrying arms correspond vertically to the drilling drill bit. Following the positioning perforation instructions, the operator adjusts the carton's intended drilling point to within the positioning perforations, enabling convenient positioning adjustments before drilling the carton, improving drilling accuracy. The operator sequentially loads and unloads cartons on multiple carrying arms, thereby improving the drilling efficiency of the present invention's drilling device for carton production.
