[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. In the production process of cardboard boxes, it is often necessary to fold the edges of the cut and creased cardboard boards. However, most companies now use manual folding to fold the edges of the cardboard boards. Manual folding is not only inefficient and wasteful of manpower, but also because the manual folding process cannot limit the position of the cardboard board, which may cause the cardboard board to shift during the folding process, thus affecting the folding effect. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a folding device for carton production, including a workbench. A fixed frame is vertically mounted on the top of the workbench, and a cardboard board with creases is horizontally placed inside the fixed frame. The cardboard box is located on the top of the workbench. A pressure plate is vertically movable inside the fixed frame, with its bottom parallel to the top of the cardboard board. The bottom edge of the back of the pressure plate is aligned with the crease line of the cardboard board, and the pressure plate presses and limits the cardboard board when it moves vertically inside the fixed frame. A support plate is horizontally mounted at the bottom of the outer side of the workbench, and a top plate is movable on top of the support plate. The top plate is vertically located behind the pressure plate, and the pressure plate and the top plate are vertically offset and parallel. When the top plate moves vertically on the top of the support plate, it drives the cardboard board to move upward along the creases until the side of the cardboard board is in contact with the side of the pressure plate, thereby folding the cardboard board.

[0004] Preferably, a movable frame is movably mounted on the fixed frame, and the movable frame is laterally located on the top of the worktable, with one end of the movable frame being driven to the pressure plate.

[0005] Preferably, a foot pedal is provided between the movable frame and the worktable, and the foot pedal is located laterally at the bottom of the worktable. The foot pedal is driven to the movable frame, and the pressure plate is driven to the movable frame and the foot pedal.

[0006] Preferably, an air pump is driven to one side of the foot pedal, and the air pump is located laterally inside the workbench. The foot pedal is driven to the movable frame through the air pump. A first drive cylinder is connected to each side of the air pump through pipes. The first drive cylinder is located vertically at the top of the workbench, and one end of each first drive cylinder passes through the workbench and is driven to the movable frame.

[0007] Preferably, a plurality of second driving cylinders are provided on the support plate, and the second driving cylinders are respectively vertically located on both sides of the bottom of the support plate, and the second driving cylinders are all drivingly connected to the bottom of the top plate.

[0008] Preferably, an avoidance groove is vertically formed through the top of the workbench, and the cardboard is horizontally mounted on the top of the avoidance groove, and the top plate is located in the avoidance groove and moves synchronously in the avoidance groove when the top plate moves vertically on the top of the support plate.

[0009] Preferably, a moving limit plate is movably provided at the inner bottom end of the fixing frame, and the bottom of the moving limit plate is parallel to the top of the workbench. The moving limit plate is horizontally located on the back of the pressing plate, and the moving limit plate and the pressing plate do not contact each other, and the front side of the moving limit plate contacts the back of the cardboard box.

[0010] Preferably, a rack is provided on the moving limit plate, and the rack is horizontally installed on both sides of the bottom of the moving limit plate, and the rack is movably matched with the moving limit plate. A gear shaft meshing with the rack is rotatably provided inside the fixing frame, and both sides of the gear shaft respectively penetrate through the fixing frame horizontally, and the gear shaft is drivingly connected to the moving limit plate through the rack.

[0011] Preferably, one end of the gear shaft is drivingly connected with a runner, and the runner rotates horizontally at the side of the fixing frame, and the runner is drivingly connected to the rack through the gear shaft.

[0012] In summary, the beneficial effects of the present application are as follows:

[0013] 1. The pressing plate is in a "U" shape and is vertically located inside the fixing frame. Taking the indentation line as a reference, one side of the indentation line is the front half of the cardboard box, and the other side of the indentation line is the back half of the cardboard box. Therefore, when it is necessary to fold the cardboard box with indentations, only need to horizontally place the cardboard box with indentations on the top of the workbench and align the indentation with the edge at the bottom of the back of the pressing plate. At this time, the pressing plate will be parallel above the front half of the cardboard box. Then, drive the pressing plate to move vertically downward inside the fixing frame until the bottom of the pressing plate contacts and presses the top of the front half of the cardboard box, so as to press the cardboard box between the pressing plate and the workbench, thereby realizing the limitation of the cardboard box. At this time, the edge at the bottom of the back of the pressing plate and the indentation line of the cardboard box are in contact with each other.

[0014] 2. After the cardboard is positioned, the worker drives the top plate to move vertically upwards from the top of the support plate. During this upward movement, the rear half of the cardboard moves upwards along the crease until the angle between the rear and front halves is 90 degrees. At this point, the side of the rear half of the cardboard will be in contact with the side of the pressure plate, thus achieving the folding operation. Through the cooperation of these structures, not only is the cardboard positioned correctly, preventing displacement during folding, but the folding method using the pressure plate and top plate replaces manual folding, effectively improving work efficiency. This effectively solves the technical problem that most companies currently use manual folding, which is inefficient, wastes manpower, and prevents the cardboard from shifting during folding, affecting the folding effect.

[0025] A folding device for cardboard box production, see [link / reference] Figures 1 to 4The system includes a workbench 1, a fixed frame 2 vertically mounted on top of the workbench 1, and a cardboard box 3 with embossing placed horizontally inside the fixed frame 2. The cardboard box is located on top of the workbench 1. A pressure plate 4 is vertically movable inside the fixed frame 2, with the bottom of the pressure plate 4 parallel to the top of the cardboard box 3. The bottom edge of the back of the pressure plate 4 is aligned with the embossing line of the cardboard box 3, and the pressure plate 4 presses and limits the cardboard box 3 when it moves vertically inside the fixed frame 2. A support plate 5 is horizontally mounted at the bottom of the outer side of the workbench 1, and a top plate 6 is movable on top of the support plate 5. The top plate 6 is vertically located behind the pressure plate 4, and the pressure plate 4 and the top plate 6 are vertically offset. When the top plate 6 moves vertically on top of the support plate 5, it drives the cardboard board 3 to move upward along the crease until the side of the cardboard board 3 is in contact with the side of the pressure plate 4, thereby achieving the folding of the cardboard board 3. In this embodiment, the pressure plate 4 is shaped like a "U" and is vertically located inside the fixing frame 2. With the crease line as the reference, one side of the crease line is the front half of the cardboard board 3, and the other side of the crease line is the rear half of the cardboard board 3. Therefore, when it is necessary to fold the cardboard board 3 with creases, it is only necessary to place the cardboard board 3 with creases horizontally on the top of the workbench 1 and align the crease with the bottom edge of the back of the pressure plate 4. At this time, the pressure plate 4 will be parallel above the front half of the cardboard board. Then, the pressure plate is driven to move upward along the crease until the side of the cardboard board 3 is in contact with the side of the pressure plate 4. 4. The pressure plate 4 moves vertically downward inside the fixed frame 2 until its bottom contacts and presses against the top of the front half of the cardboard board 3, thus fixing the cardboard board 3 between the pressure plate 4 and the worktable 1, thereby limiting the position of the cardboard board 3. At this time, the bottom edge of the back of the pressure plate 4 is in contact with the crease line of the cardboard board 3. After the cardboard board 3 is properly positioned, the operator drives the top plate 6 to move vertically upward on top of the support plate 5. During the vertical upward movement of the top plate 6, the rear half of the cardboard board 3 is simultaneously driven to move upward along the crease until the angle between the rear half and the front half of the cardboard board 3 is 90 degrees. At this time, the side of the rear half of the cardboard board 3 will fit against the side of the pressure plate 4, thereby achieving the desired position. The cardboard board 3 undergoes an edge-folding operation. Through the cooperation of the above-mentioned structures, not only can the cardboard board 3 be limited to prevent it from shifting position during the edge-folding operation, but the method of edge-folding the cardboard board 3 by the cooperation of the pressure plate 4 and the top plate 6 also replaces manual edge-folding, effectively improving work efficiency. This effectively solves the technical problem that most companies currently use manual edge-folding for cardboard board 3, which is not only inefficient and wasteful of manpower, but also because manual edge-folding cannot limit the position of the cardboard board 3 during the edge-folding operation, causing the cardboard board 3 to shift position during the edge-folding operation, thus affecting the edge-folding effect.

[0026] A movable frame 7 is movably mounted on the fixed frame 2, and the movable frame 7 is laterally located at the top of the workbench 1. One end of the movable frame 7 is driven to the pressure plate 4. A foot pedal 8 is provided between the movable frame 7 and the workbench 1, and the foot pedal 8 is laterally located at the bottom of the workbench 1. The foot pedal 8 is driven to the movable frame 7, and the pressure plate 4 is driven to the foot pedal 8 through the movable frame 7. An air pump 9 is driven to one side of the foot pedal 8, and the air pump 9 is laterally located inside the workbench 1. The foot pedal 8 is driven to the movable frame 7 through the air pump 9. Each side is connected to a first drive cylinder 10 via pipes. The first drive cylinder 10 is vertically located at the top of the workbench 1, and one end of each first drive cylinder 10 passes through the workbench 1 and is connected to the movable frame 7. In this embodiment, after the worker places the cardboard 3 with dents horizontally on the top of the workbench 1 and aligns the dents with the bottom edge of the back of the pressure plate 4, the worker can step on the foot pedal 8. When the foot pedal 8 is stepped on, the air pump 9 is driven to supply air to the first drive cylinder 10. At this time, the first drive cylinder 10 drives the movable frame 7. The pressure plate 4 moves downward inside the fixed frame 2 until its bottom contacts and presses against the top of the front half of the cardboard board 3, thus fixing the cardboard board 3 between the pressure plate 4 and the workbench 1. This limits the cardboard board 3, allowing the top plate 6 to begin folding the cardboard board 3. During the folding process, the foot pedal 8 remains depressed. Once the folding is complete, the worker can remove their foot from the foot pedal 8. The moment the foot is removed, the force on the foot pedal 8 disappears, simultaneously stopping the air pump 9. Air is supplied to the first drive cylinder 10. At this time, the foot pedal 8 gradually returns to its original position. The movable frame 7, together with the pressure plate 4, gradually moves upward inside the fixed frame 2 as the foot pedal 8 returns to its original position until it returns to its original position. At this time, the folded carton board 3 can be picked up. In this embodiment, the method of using the foot to drive the foot pedal 8 to drive the pressure plate 4 to press and limit the carton board 3 replaces the traditional method of using the hand to drive the pressure plate 4 to press and limit the carton board 3. This not only reduces the hand operation of the workers, but also reduces the workload of the workers, effectively improving the practicality of this embodiment.

[0027] The support plate 5 is provided with a plurality of second driving cylinders 11, and the second driving cylinders 11 are respectively vertically located on both sides of the bottom of the support plate 5. The second driving cylinders 11 are all connected to the bottom of the top plate 6. In this embodiment, after the carton board 3 is positioned, the top plate 6 can be driven to move vertically upward on the top of the support plate 5 by the second driving cylinders 11. During the vertical upward movement of the top plate 6, the rear half of the carton board 3 will be driven to move upward along the crease until the angle between the rear half and the front half of the carton board 3 is 90 degrees. At this time, the side of the rear half of the carton board 3 will be in contact with the side of the pressure plate 4, thereby realizing the folding operation of the carton board 3.

[0028] The top of the workbench 1 is vertically formed with a clearance groove 12, and the cardboard is horizontally supported on the top of the clearance groove 12. The top plate 6 is located in the clearance groove 12 and moves synchronously within the clearance groove 12 when the top plate 6 moves vertically on the top of the support plate 5. In this embodiment, when the cardboard board 3 is pressed and fixed between the pressure plate 4 and the workbench 1, the front half of the cardboard board 3 will be located on the top of the workbench 1, and the rear half of the cardboard board 3 will be horizontally supported on the top of the clearance groove 12, while the top plate 6 is located in the clearance groove 12. After the cardboard board 3 is in position, the worker drives the top plate 6 to move vertically upward on the top of the support plate 5. During the vertical upward movement of the top plate 6, the rear half of the cardboard board 3 will be driven to move upward along the indentation. After the cardboard board 3 is in position, the worker drives the top plate 6 to move vertically upward on the top of the support plate 5. During the vertical upward movement of the top plate 6, the rear half of the cardboard board 3 will be driven to move upward along the indentation.

[0029] A movable limiting plate 13 is movably disposed at the bottom of the fixed frame 2, and the bottom of the movable limiting plate 13 is parallel to the top of the workbench 1. The movable limiting plate 13 is laterally located on the back of the pressure plate 4, and the movable limiting plate 13 and the pressure plate 4 do not contact each other. The front side of the movable limiting plate 13 contacts the back of the carton board 3. A rack 14 is disposed on the movable limiting plate 13, and the rack 14 is laterally installed on both sides of the bottom of the movable limiting plate 13, and the rack 14 and the movable limiting plate 13 are in movable engagement. A gear shaft 15 is rotatably disposed inside the fixed frame 2, meshing with the rack 14. The gear shaft 15 is laterally inserted through the fixed frame 2 on both sides, and the gear shaft 15 is drivenly connected to the movable limiting plate 13 through the rack 14. The end drive is connected to a rotating wheel 16, which rotates laterally on the side of the fixed frame 2. The rotating wheel 16 is driven to connect to the rack 14 via a gear shaft 15. In this embodiment, by providing a movable limiting plate 13, not only can the side of the carton board 3 be limited so that the carton board 3 will not shift position, but also when the gear shaft 15 and the rack 14 mesh for transmission, it is only necessary to drive the rotating wheel 16 to rotate on the side of the fixed frame 2. Then, through the mutual cooperation between the gear shaft 15 and the rack 14, the movable limiting plate 13 can be driven to move laterally back and forth inside the fixed frame 2, thereby changing the distance between the movable limiting plate 13 and the pressure plate 4. This allows this embodiment to adapt to the folding work of different types of carton boards 3, effectively improving the practicality of this embodiment.

[0030] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
