The tape sealer 19 is located between the two conveying devices 15 and corresponds to the guide frame 12.

[0032] In this embodiment, when opening the carton, the stacked carton boards are placed on the storage frame 2. The carton boards slide between the fixed baffle 3 and the adjustable baffle 4. The forming baffle assembly 6 restricts the carton boards to prevent them from falling. A belt drive module 7 controls the movement of the suction box bracket 8. The suction box bracket 8 drives the suction cup assembly 10 to adsorb the carton boards on the storage frame 2, moving the carton boards between the guide frame 12 and the pusher plate 11. During the movement, the carton boards first contact the curved end of the pusher plate 11, which opens the carton boards into a carton. The carton is then adsorbed and suspended between the guide frame 12 and the pusher plate 11 by the suction cup assembly 10. Two first cylinders 13 control two first folding plates 14 to rotate upwards by 90 degrees. The two first folding plates 14 respectively contact the bottom of the carton.

The suction cup assembly 10 cancels the suction on the carton. The pusher plate 11 pushes the carton to slide between the two conveying devices 15 at the top of the guide frame 12. The two conveying devices 15 transport the carton. During the carton transport, the pressure plate assembly 5 restricts the top of the carton. The two second cylinders 17 in the two fixed brackets 16 control the two second folding plates 18 to rotate upward. The two second folding plates 18 fold the front and rear bottom covers of the carton, so that all the bottom covers of the carton are folded. Finally, the two conveying devices 15 continue to transport the carton, so that the bottom of the carton passes through the tape sealer 19. The tape sealer 19 uses tape to seal the bottom of the carton, completing the entire opening of the carton.

[0033] Specifically, a sliding shaft assembly 20 is fixedly connected to the bottom of the storage frame 2, and a pressure box baffle 21 is slidably connected to the outer surface of the sliding shaft assembly 20, with the pressure box baffle 21 extending through to the upper side of the storage frame 2.

[0034] In this embodiment, when the stacked cardboard boxes are stored on the storage frame 2, the pressure baffle 21 slides on the storage frame 2 via the sliding shaft assembly 20, which can press down the cardboard boxes so that the cardboard boxes can continuously slide downwards for feeding.

[0035] Specifically, a one-way screw adjustment module 22 is rotatably connected inside the storage frame 2, and an adjustable baffle 4 is fixedly connected to the one-way screw adjustment module 22.

[0036] In this embodiment, the adjustable baffle 4 can be controlled to slide on the storage frame 2 by the one-way screw adjustment module 22, so as to adjust the distance between the fixed baffle 3 and the adjustable baffle 4 to accommodate cardboard of different sizes.

[0037] Specifically, a one-way screw lifting module 23 is rotatably connected inside the frame 1, and the storage frame 2 is fixedly connected to the one-way screw lifting module 23.

[0038] In this embodiment, the one-way screw lifting module 23 is used to control the height of the storage frame 2 so that the top of the cardboard boxes of different sizes can contact the forming stop bar assembly 6, which facilitates the forming stop bar assembly 6 to restrict the cardboard boxes.

[0039] Specifically, two slide rail assemblies 24 are fixedly connected inside the frame 1, and the suction box bracket 8 and the push box bracket 9 are slidably connected to the two slide rail assemblies 24 respectively.

[0040] In this embodiment, both belt drive modules 7 are controlled by motors. They use the principle of belt drive to drive the suction box bracket 8 and the push box bracket 9 to move, thereby realizing the picking up of cardboard and the pushing of cardboard boxes.

[0041] Specifically, a one-way screw adjustment module 25 is rotatably connected inside the frame 1, and the pressure plate assembly 5 is fixedly connected to the one-way screw adjustment module 25.

[0042] In this embodiment, the one-way lead screw adjustment module 25 is used to control the height of the pressure plate assembly 5 and the forming stop bar assembly 6, so that the pressure plate assembly 5 and the forming stop bar assembly 6 contact the top of the carton board and the carton to accommodate the opening of cartons of different sizes.

[0043] Specifically, a bidirectional lead screw adjustment module 26 is rotatably connected inside the frame 1, and both transmission devices 15 are fixedly connected to the two bidirectional lead screw adjustment modules 26.

[0044] In this embodiment, the bidirectional lead screw pitch adjustment module 26 adopts bidirectional control, which can simultaneously adjust the distance between the two conveying devices 15, so that the two conveying devices 15 can adapt to the conveying of cartons of different widths.

[0045] Working principle: When opening a carton, the stacked cardboard boxes are stored between the fixed baffle 3 and the adjustable baffle 4 on the storage frame 2. The carton is restricted by the forming baffle assembly 6 and corresponds to the suction cup assembly 10. A belt drive module 7 controls the movement of the suction box bracket 8. The suction box bracket 8 drives the suction cup assembly 10 to attract the cardboard boxes on the storage frame 2, causing the cardboard boxes to move between the guide frame 12 and the pusher plate 11. During the movement, the cardboard boxes first contact the curved end of the pusher plate 11 and open. The opened carton is attracted by the suction cup assembly 10 and suspended between the guide frame 12 and the pusher plate 11. Two first cylinders 13 control two first folding plates 14 to rotate upward by 90 degrees respectively. The two first folding plates 14 respectively align with the left side of the bottom of the carton. The two bottom covers on the right are folded together. Then, another belt drive module 7 controls the pusher bracket 9 to move closer to the guide frame 12. At the same time, the suction cup assembly 10 cancels the suction on the carton. The pusher bracket 9 drives the pusher plate 11 to push the carton to slide at the top of the guide frame 12. The carton enters the two conveying devices 15 for conveying. The pressure plate assembly 5 restricts the top of the carton. The two second cylinders 17 in the two fixed brackets 16 control the two second folding plates 18 to rotate upward. The two second folding plates 18 fold the front and rear bottom covers of the carton, so that all the bottom covers of the carton are folded. Finally, the two conveying devices 15 continue to convey the carton, so that the bottom of the carton passes through the tape sealer 19. The tape sealer 19 uses tape to seal the bottom of the carton.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
