Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Embodiment 1

[0030] Please refer to Figures 1 - 7 , a cardboard bundling machine, including a bearing platform 1 and a strap reel 2 arranged beside the bearing platform 1. The upper surface of the bearing platform 1 is rotatably connected with a rotating disk 3. The lower surface of the rotating disk 3 is fixedly connected with a rotating ring 4 adapted to the bearing platform 1. The lower surface of the bearing platform 1 is fixedly installed with a first driving motor 5. The output end of the first driving motor 5 is fixedly installed with a first gear 6. The inner side wall of the rotating ring 4 is provided with a tooth groove 7 adapted to the first gear 6. The upper surface of the rotating disk 3 is slidably connected with a plurality of alignment plates 8. The rotating disk 3 is internally provided with a driving unit 9 for driving the alignment plates 8 to move towards or away from each other simultaneously. The rotating disk 3 is provided with a placing platform 10. The upper surface of the placing platform 10 is provided with a plurality of opening grooves 11. The upper surface of the rotating disk 3 is provided with a cover plate 24. The cover plate 24 is fixedly installed on the rotating disk 3 through fasteners. The placing platform 10 is arranged on the upper surface of the cover plate 24. The upper surface of the cover plate 24 is fixedly connected with a plug-in block 25. The lower surface of the placing platform 10 is provided with a plug-in slot 26 adapted to the plug-in block 25. The number of alignment plates 8 is at least two.

[0031] Specific implementation in this embodiment: When bundling a stack of cardboard, place the stack of cardboard on the placement table 10 through mechanical equipment. Start the driving unit 9 to drive several alignment plates 8 to move towards each other. Align each side of the stack of cardboard through the alignment plates 8. Thread the bundling tape on the bundling tape reel 2 through the opening groove 11, bypass the aligned stack of cardboard, and use a packing tool to tighten and fix the bundling tape. After bundling two opposite sides of the stack of cardboard, cut the bundling tape. Start the first driving motor 5. The output end of the first driving motor 5 drives the first gear 6 to rotate. The first gear 6 meshes with the tooth groove 7, and then the rotating ring 4 rotates. The rotating ring 4 drives the rotating disk 3 to rotate, thereby driving the stack of cardboard on the placement table 10 to rotate, and bundling the two sides of the stack of cardboard through the bundling tape passing through the opening groove 11, improving the stability of the bundled stack of cardboard and the bundling efficiency of the stack of cardboard. At the same time, the cover plate 24 is installed on the rotating disk 3 through fasteners such as screws, facilitating the installation and maintenance of the internal parts of the rotating disk 3. The insertion block 25 is polygonal and adapted to the insertion slot 26. The placement table 10 can be replaced according to the size of the cardboard to prevent the placement table 10 from being too large or too small from interfering with the alignment of the stack of cardboard by the alignment plates 8. If the placement table 10 is too large and the cardboard is too small, it will block the alignment of the stack of cardboard by the alignment plates 8. If the placement table 10 is too small and the cardboard is too large, the side of the stack of cardboard will collapse downward, and it will also cause the alignment plates 8 to be unable to align the stack of cardboard. The number of alignment plates 8 can be determined according to the number of sides of the actual cardboard. For example, if the cardboard is triangular, the number of alignment plates 8 is three. If the cardboard is quadrilateral or pentagonal, the number of alignment plates 8 is four or five, improving the applicability of the overall device.

[0032] Among them, the first driving motor 5 above can be purchased on the market. It belongs to mature technology and has been fully disclosed. Therefore, it is not repeated in the specification. The first driving motor 5 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power cord. And the main controller can be a conventional known device such as a computer that plays a control role.

[0035] Specific implementation method in this embodiment: When it is necessary to align the side of the cardboard stack, start the second drive motor 14. The output end of the second drive motor 14 drives the third gear 15 to rotate. The third gear 15 drives the toothed ring 12 to rotate. When the toothed ring 12 rotates, it drives the second gear 13 to rotate. When the second gear 13 rotates, it drives the moving plates 16 to move towards or away from each other. The moving plates 16 drive the alignment plates 8 to move, thereby simultaneously aligning multiple sides of the cardboard stack. Moreover, by using one second drive motor 14 to simultaneously drive several alignment plates 8 to move, the synchronism when several alignment plates 8 move is improved.
