[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 4The utility model provides an embodiment: a folding device for carton processing with good buffering performance. The cardboard of the carton is a multi-layer structure. There are certain gaps between the multi-layer cardboards. When subjected to external force impact, the external impact force will first deform the outer cardboard, while the middle layer of cardboard and the gap can absorb and disperse energy, reducing the direct impact on the internal items, and has good buffering performance. It includes a base 1, the base 1 is arranged in a rectangular shape, and the base 1 is arranged to provide support for the installation of the column 2 and the base 7. The base 7 is fixedly connected to the outer wall of the upper end of the base 1, and the base 7 is arranged to provide support for the sliding of the expansion plate 11. A dual-axis motor 13 is fixedly connected to the inner wall of the upper end of the base 7. The operation of the dual-axis motor 13 drives the screw rods 14 connected at both ends to rotate. The screw rod 14 is rotatably connected to the inner wall of the upper end of the base 7. The screw rod 14 drives the expansion plate 11 to move at the upper end of the base 7 through the operation of the dual-axis motor 13. The inner wall of the left end of the screw rod 14 is fixedly connected to the output shaft of the dual-axis motor 13. The expansion plate 11 is slidably connected to the outer wall of the upper end of the base 7. The expansion plate 11 can be moved on the base 7 by the rotation of the screw rod 14 so that the edge of the expansion plate 11 moves to the position where the carton board is to be folded, so as to meet the folding requirements of different positions of the carton board.

[0032] Furthermore, the inner wall of the left end of the expansion plate 11 is threadedly connected to the outer wall of the screw rod 14, and the expansion plate 11 is provided with two symmetrical pieces. The upper outer wall of the machine base 1 is fixedly connected to a column 2, and four columns 2 are provided. The column 2 provides support for the sliding of the bracket 4 and the fixation of the top plate 15. The outer wall of the column 2 is penetrated and slidably connected with the bracket 4. The bracket 4 drives the slider 3 and the fixed block 6 to slide along the outer wall of the column 2 through the operation of the electric telescopic rod 5. The upper inner wall of the bracket 4 is penetrated and slidably connected with the slider 3. The slider 3 drives the folding plate 12 to move through the movement of the bracket 4. The folding plate 12 is fixedly connected to the outer wall of the bottom end of the slider 3. The folding plates 12 on both sides move down at the same time to simultaneously adjust the two sides of the carton board. Folding saves time on folding. The folding plates 12 are set into two pieces. The two folding plates 12 are symmetrically set. The folding plates 12 are L-shaped. The bottom outer wall of the folding plate 12 is fixedly connected with a guide rod 10. The guide rod 10 drives the folding plate 12 to move and adjust its position through the horizontal movement of the expansion plate 11. The guide rod 10 provides support for the vertical movement of the folding plate 12. There are two groups of guide rods 10. Each group of guide rods 10 is two symmetrical ones. The outer wall of the guide rod 10 passes through and is slidably connected to the upper outer wall of the expansion plate 11. A downward pressure component is set on the upper outer wall of the column 2. The downward pressure component is used for the movement of the bracket 4. A pre-pressing component is set on the bottom outer wall of the bracket 4. The pre-pressing component is used to fix the carton board.

[0033] Reference Figure 1 and Figure 2The pre-pressing assembly includes a fixed block 6, which is T-shaped. The fixed block 6 provides support for the movement of the pressure plate 9. The fixed block 6 moves downward with the bracket 4, and finally the outer wall of the bottom end of the fixed block 6 squeezes the outer wall of the upper end of the carton board to fix the carton board and prevent the carton board from deflecting. The outer wall of the upper end of the fixed block 6 is fixedly connected to the outer wall of the bottom end of the bracket 4, and the outer wall of the upper right end of the fixed block 6 is elastically connected to the pressure plate 9 through a spring 8. The downward pressure of the pressure plate 9 can provide a pre-pressure to the carton board. The position of the carton board can be determined by observing the position of the pre-pressed carton board to determine whether the position of the carton board needs to be adjusted. The pressure plate 9 is Z-shaped, and the outer wall of the left end of the pressure plate 9 is slidably connected to the inner wall of the right end of the fixed block 6. One end of the spring 8 is fixedly connected to the outer wall of the upper end of the pressure plate 9, and the other end of the spring 8 is fixedly connected to the outer wall of the bottom end of the bracket 4.

[0034] Reference Figure 1 The downward pressure assembly includes a top plate 15, which is provided to provide support for the installation of the electric telescopic rod 5. The bottom outer wall of the top plate 15 is fixedly connected to the upper outer wall of the column 2. The electric telescopic rod 5 is fixedly connected to the bottom outer wall of the top plate 15. The operation of the electric telescopic rod 5 drives the movement of the bracket 4.

[0035] Working principle: By placing the carton board on the upper outer wall of the base 7, the position to be folded is determined, and the dual-axis motor 13 is started. The operation of the dual-axis motor 13 drives the two connected screws 14 to rotate, and the rotation of the screw rods 14 drives the threaded expansion plate 11 to move away from the center direction of the base 7, so that the outer edge of the expansion plate 11 moves to the position to be folded. The movement of the expansion plate 11 drives the folding plate 12 to move synchronously through the guide rod 10, and the movement of the folding plate 12 drives the slider 3 to slide on the upper inner wall of the bracket 4. After the position adjustment is completed, the electric telescopic rod 5 is started to drive the bracket 4 to move downward. In the process of the bracket 4 moving downward, the outer wall of the bottom end of the pressing plate 9 first contacts the outer wall of the upper end of the carton board to pre-press the carton board. According to the position of the pre-pressed carton board, it is determined whether the position of the carton board needs to be adjusted. If adjustment is required, it is adjusted. As the bracket 4 continues to move downward, the folding plate 12 moves downward to perform folding operation on the carton board.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
