Detailed Implementation

[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 Figures 1-4This utility model provides a technical solution: a folding mechanism for carton production and processing, including a device housing 1 and a support leg 2. The support leg 2 is fixedly connected to the lower part of the device housing 1. A folding device is installed on the inner side of the device housing 1. The folding device includes a folding unit and a feeding unit. The folding unit is installed on the inner side of the device housing 1, and the feeding unit is installed on the inner side of the device housing 1.

[0024] The crease unit includes a motor 3, which is mounted on the side of the device housing 1. The output shaft of the motor 3 is driven by a drive shaft 4. A slit conveyor belt 5 is movably connected to the outer surface of the drive shaft 4. A drive belt assembly 6 is driven by the outer surface of the drive shaft 4 away from the motor 3. A vertical plate 7 is fixedly connected to the top of the device housing 1. A rotating shaft 8 is driven by the other end of the drive belt assembly 6. A movable plate 9 is movably connected to the outer surface of the rotating shaft 8 and inside the vertical plate 7. A connecting rod 10 is fixedly connected to the inner side of the movable plate 9. A connecting sleeve 11 is fixedly connected to the outer surface of the connecting rod 10. An upper protruding plate 12 is fixedly connected to the bottom of the connecting sleeve 11. A drive belt assembly 14 is driven by the outer surface of the drive shaft 4. A rotating shaft 15 is driven by the other end of the drive belt assembly 14. A drive assembly 19 is driven by the outer surface of the rotating shaft 15. A drive belt assembly 20 is driven by the inside of the drive assembly 19. A push rod assembly 21 is driven by the other end of the drive belt assembly 20. A connecting sleeve 22 is fixedly connected to the outer surface of 21. A concave plate 23 is fixedly connected to the top of the connecting sleeve 22. By installing the crease unit, the carton to be creased is placed on the slitting conveyor belt 5. By starting the motor 3, the motor 3 drives the transmission shaft 4 to rotate, which in turn causes the slitting conveyor belt 5 to move the carton to be creased. When the transmission shaft 4 rotates, it drives the rotating shaft 8 and the rotating shaft 15 to rotate through the transmission belt assembly 11 and the transmission belt assembly 21 respectively. When the rotating shaft 8 rotates, it drives the movable plate 9, which in turn causes the connecting rod 10 to rotate. This causes the upper convex plate 12 to move up and down through the connecting sleeve 11. When the rotating shaft 15 rotates, it drives the transmission belt assembly 3 20 through the transmission assembly 19, which in turn causes the push rod assembly 21 to drive the connecting sleeve 22, which causes the concave plate 23 to move upward. Then, the upper convex plate 12 and the concave plate 23 are connected to crease the carton.

[0025] The transmission assembly 19 consists of two meshing gears. Gear 1 is fixedly connected to the outer surface of the rotating shaft 15, and gear 2 is connected to one side of the transmission belt assembly 20. Thus, when the rotating shaft 15 rotates, gear 1 and gear 2 mesh with each other, thereby causing the transmission belt assembly 20 to move.

[0026] A limiting rod 13 is fixedly connected to the outer side of the upright plate 7, thereby further limiting the movement trajectory of the upper convex plate 12 and the lower concave plate 23 by installing the limiting rod 13, thereby improving the crease quality of the device.

[0027] Hydraulic telescopic rods are installed on the inner sides of both the connecting sleeve 11 and the push rod assembly 21. By activating the hydraulic telescopic rods, the depth of the crease can be further adjusted. At the same time, the device can be adapted to cartons of different thicknesses, thereby improving the practicality of the device.

[0028] A protective layer is installed on the bottom of the upper convex plate 12 and the inner side of the lower concave plate 23. The inner side of the protective layer is provided with anti-slip texture. By installing the protective layer, the damage to the carton when the upper convex plate 12 and the lower concave plate 23 are squeezed inward is further reduced, thereby further improving the quality of carton crease production.

[0029] The unloading unit includes a rotating disk 16, which is driven to the outside of the rotating shaft 15. A connecting plate 17 is movably connected to the outside of the rotating disk 16, and a horizontal moving plate 18 is movably connected to the other end of the connecting plate 17. A collecting shell 24 is movably connected to the bottom of the device housing 1. By installing the unloading unit, when the rotating shaft 15 rotates, the rotating disk 16 is driven to rotate, which in turn causes the connecting plate 17 to push the horizontal moving plate 18 to move horizontally, thereby pushing the creased carton into the inside of the collecting shell 24. This completes the auxiliary unloading of the creased carton, ensuring that the device can operate normally.

[0030] The collection housing 24 is located below the concave plate 23.

[0031] Working principle: Place the carton requiring creases on the slitting conveyor belt 5, start the motor 3, and the motor 3 drives the drive shaft 4 to rotate, causing the slitting conveyor belt 5 to move the carton; when the drive shaft 4 rotates, it drives the rotating shaft 8 and the rotating shaft 15 to rotate through the drive belt assembly 6 and the drive belt assembly 14 respectively; the rotation of the rotating shaft 8 drives the movable plate 9 and the connecting rod 10 to rotate, causing the connecting sleeve 11 to drive the upper convex plate 12 to move up and down; when the rotating shaft 15 rotates, it drives the drive belt assembly 20 to move through the drive assembly 19, which consists of two meshing gears (gear 1 is fixed on the outer surface of the rotating shaft 15, and gear 2 is connected to one side of the drive belt assembly 20), causing the push rod assembly 21 to move. The moving connecting sleeve 22 and the lower concave plate 23 move upward, and the upper convex plate 12 aligns with the lower concave plate 23 to crease the carton; the limiting rod 13 on the outside of the upright plate 7 limits the movement trajectory of the upper convex plate 12 and the lower concave plate 23; the hydraulic telescopic rod inside the connecting sleeve 11 and the push rod assembly 21 can adjust the crease depth and adapt to cartons of different thicknesses; the protective layer and anti-slip texture on the bottom of the upper convex plate 12 and the inside of the lower concave plate 23 reduce damage to the carton; during feeding, the rotating shaft 15 drives the rotating disk 16 to rotate, causing the connecting plate 17 to push the horizontal moving plate 18 to move horizontally, pushing the creased carton into the collecting shell 24 located below the lower concave plate 23 to complete the auxiliary feeding and ensure the normal operation of the device.
