Description

Technical Field

[0001] This utility model relates to the field of cardboard folding technology, specifically to a cardboard packaging box folding mold. Background Technology

[0002] Cardboard packaging boxes are containers made primarily of cardboard, processed through cutting, folding, and gluing. Corrugated cardboard is the most common material for cardboard packaging boxes, consisting of face paper, liner paper, core paper, and corrugated paper bonded together. It is often used to package heavier or fragile items. A cardboard packaging box folding mold is a specialized tool used to quickly and accurately fold flat cardboard into a specific shape. Through its ingenious structural design, it guides the cardboard through folding and forming processes, greatly improving production efficiency and quality. It is used to produce packaging boxes for various foods, such as biscuit boxes, chocolate boxes, and mooncake boxes. These boxes typically require good appearance and sealing, and the mold meets their precise requirements for shape and size. It is also used to produce packaging boxes for electronic products such as mobile phones, tablets, and cameras. Electronic product packaging boxes need to protect the product and showcase its features, and the mold ensures a sturdy structure and attractive appearance. It is also suitable for producing packaging boxes for daily necessities such as shampoo, shower gel, and cosmetics.

[0003] According to Chinese Patent Publication No. CN211591492U, a packaging box industrial cardboard forming mold includes a polygonal column. The top of the polygonal column has a polygonal boss, and multiple sides of the boss correspond to multiple sides of the column. Each side of the boss is 5-50mm inward from the corresponding side of the column. One or more sides of the column have protruding blocking portions at their lower parts, which are integrally formed with or connected to the column. A recessed vertical groove is provided at the corner between two adjacent sides of the column. This invention has the following advantages: the bottom plate and side plates can form a standard right angle after bonding; the bonding edge of the side plates can be kept straight; the bonding position of the product is accurate, ensuring the inner diameter and appearance flatness of the product, thus improving the quality of the finished product; the intensity of manual labor is reduced, and subsequent cleaning and inspection processes are unnecessary, saving labor and time costs and improving production efficiency.

[0004] In the above solution, a standard right angle can be formed by bonding the base plate and the side plate, ensuring the straightness of the bonded edge of the side plate and accurate positioning of the product's bonding point. This ensures the product's inner diameter and appearance flatness, improving the quality of the finished product. However, this solution has the following drawbacks: the existing cardboard folding head is fixed and cannot be adjusted in size, allowing only one type of cardboard to be folded at a time. Once folded, the cardboard is inconvenient to remove from the forming groove, reducing processing efficiency, time and labor costs, flexibility, and practicality. Furthermore, each time the cardboard needs to be manually inserted into the forming groove, workers are prone to injury if they are not careful, posing a safety hazard. This wastes time and energy, reduces work efficiency, and lowers safety. Therefore, a cardboard packaging box folding mold is urgently needed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a cardboard packaging box folding forming mold. The main body 1 has a shell 2 on its top surface, and an electric push rod 3 is fixedly connected to the bottom surface of the shell 2. The telescopic end of the electric push rod 3 is fixedly connected to a hollow plate 4. A placement plate 17 is fixedly connected to one side of the main body 1, and a fixing plate 19 is fixedly connected to one side of the placement plate 17. The hollow plate 4 has an adjustment component for folding different sizes of cardboard packaging boxes, and the fixing plate 19 has a moving component for automatically placing cardboard into the mold. The adjustment component includes a first motor 5, which is fixedly connected to the hollow plate 4. The output end of the first motor 5 is fixedly connected to a first bevel gear 6, and a second bevel gear 7 is provided on the first bevel gear 6. The second bevel gear 7 meshes with the first bevel gear 6. A first bidirectional threaded rod 9 is rotatably connected to one side inside the hollow plate 4, and the first bidirectional threaded rod 9 is fixedly connected to the second bevel gear 7. A worm gear 13 is fixedly sleeved on the outer surface of the threaded rod 9. A worm wheel 14 is provided on the worm gear 13 and meshes with the worm gear 13. A second bidirectional threaded rod 15 is rotatably connected to one side of the hollow plate 4. The outer wall of the second bidirectional threaded rod 15 is fixedly connected to the worm wheel 14. Two first moving plates 10 are threadedly connected to the first bidirectional threaded rod 9. A second bending head 12 is fixedly connected to the bottom surface of the two first moving plates 10. Two second moving plates 16 are threadedly connected to the second bidirectional threaded rod 15. A first bending head 11 is fixedly connected to the bottom surface of the two second moving plates 16. A transition plate 8 is rotatably connected to the outer wall of the output end of the first motor 5. A first support rod is rotatably connected to one side of the hollow plate 4 and passes through the first moving plate 10. A second support rod is rotatably connected to one side of the hollow plate 4 and passes through the second moving plate 16.

[0024] Working principle: The electric push rod 3 moves the hollow plate 4 downwards, then the first motor 5 drives the first bevel gear 6 to rotate. The first bevel gear 6 then drives the meshing second bevel gear 7 to rotate, which in turn drives the first bidirectional threaded rod 9 to rotate. The first bidirectional threaded rod 9 rotates on the hollow plate 4, then drives the two threaded first moving plates 10 to move outwards. The two first moving plates 10 then drive the second bending head 12 to move outwards. The first bidirectional threaded rod 9 then drives the worm gear 13 to rotate, which in turn drives the meshing worm wheel 14 to rotate. The worm wheel 14 then drives the second bidirectional threaded rod 15. The rotation causes the second bidirectional threaded rod 15 to drive the two threaded second moving plates 16 to move outward. Then, the two second moving plates 16 drive the first bending head 11 to move outward. This allows one motor to quickly drive four bending heads to move outward or inward, facilitating the folding of cardboard of different sizes. After bending, the four bending heads can be moved outward to fit the cardboard and apply outward force. Then, the electric push rod 3 can be activated to remove the cardboard from the forming groove 24. This improves the overall quality of the product, reduces production costs, reduces labor costs, reduces cardboard waste, improves work efficiency, is convenient and quick, saves time, enhances flexibility, expands the scope of application, and is easy to operate while saving manpower.

[0025] Please see Figure 1-6 The mobile component provided by this utility model includes a second motor 20, which is fixedly connected to a fixed plate 19. A third bidirectional threaded rod 21 is fixedly connected to the output end of the second motor 20. Two connecting plates 22 are threadedly connected to the third bidirectional threaded rod 21. A guide plate 23 is fixedly connected to one side of the two connecting plates 22. An extension rod is fixedly connected to one side of the fixed plate 19 and passes through the connecting plate 22. A third motor is fixedly connected to one side of the placement plate 17. A conveyor belt 18 is installed on the output end of the third motor. A forming groove 24 is provided on the main body 1. Two thickened plates 25 are fixedly connected to the inner wall of the forming groove 24. Sliding grooves 26 are provided on the two thickened plates 25. Sliding plates 27 are slidably connected to the two sliding grooves 26. Two anti-deviation plates 28 are fixedly connected to the top surface of the main body 1. Threaded holes are provided on the connecting plates 22.

[0026] Working principle: By starting the third motor, the conveyor belt 18 rotates, moving the cardboard on the conveyor belt 18 forward. Then, the second motor 20 rotates the third bidirectional threaded rod 21, which in turn moves the two threaded connecting plates 22 inward. The two connecting plates 22 then move the guide plates 23 inward, allowing the guide plates 23 to move to the appropriate position on the conveyor belt 18 according to the width of the cardboard, preventing the cardboard from shifting. The cardboard then moves into the forming groove 24, where it is prevented from shifting by the anti-deviation plate 28. The sliding plate 27 slides on the chute 26, and the two sliding plates 27 conform to the length and width of the cardboard for easy bending. This process feeds the cardboard into the forming groove, preventing the risk of accidentally crushing hands when manually placing the cardboard into the forming groove. This improves production efficiency, significantly shortens the production cycle of packaging boxes, reduces manual operation time and labor intensity, enhances safety, lowers maintenance costs, and increases work efficiency and flexibility.
