Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7 A packaging box fastening device includes a conveyor 1 (existing technology, not detailed here), a first mounting plate 2 fixedly connected to the upper end of the conveyor 1, a hydraulic cylinder 3 mounted on the upper end of the first mounting plate 2, the output end of the hydraulic cylinder 3 penetrating the first mounting plate 2 and fixedly connected to a lifting plate 4, and an adsorption mechanism 5 mounted on the lifting plate 4. The adsorption mechanism 5 consists of a linear module and a negative pressure suction cup assembly (existing technology, not detailed here). The hydraulic cylinder 3 drives the lifting plate 4, enabling precise control of the height of the adsorption mechanism 5. To ensure accurate engagement between the top box and the bottom box, the adsorption mechanism 5 can firmly adsorb the top box, ensuring a stable engagement process, improving engagement accuracy, and reducing engagement deviation. The upper end of the conveyor 1 is fixedly connected to a second mounting plate 6, and the lower end of the second mounting plate 6 is installed with a first electric telescopic rod 7. The telescopic end of the first electric telescopic rod 7 is fixedly connected to a pressure plate 8. One side of the pressure plate 8 is bent upwards. The first electric telescopic rod 7 drives the pressure plate 8. The upward bending design of one side can quickly and efficiently engage the top box with the bottom box, improving the engagement speed.

[0025] The upper end of the conveyor 1 is fixedly connected to a limiting plate 9, which limits the top box. The upper end of the conveyor 1 is also fixedly connected to two fixing plates 10. The side walls of the two fixing plates 10 are each equipped with a second electric telescopic rod 11. The telescopic ends of the two second electric telescopic rods 11 are each fixedly connected to a clamping plate 12, which limits the bottom box. By limiting the top box with the limiting plate 9 and limiting the bottom box with the second electric telescopic rods 11 and clamping plates 12, it is possible to ensure that the top box and the bottom box remain stable during the fastening process, avoid fastening failure due to positional deviation, and ensure the fastening quality. The upper end of the conveyor 1 is also fixedly connected to two third mounting plates 13. The lower ends of the two third mounting plates 13 are each fixedly connected to a connecting rod 14. The lower ends of the two connecting rods 14 are jointly fixedly connected to a guide plate 15. The two side walls of the guide plate 15 are each provided with a rectangular groove 16.

[0026] In this system, multiple first guide rollers 17 are rotatably connected between the inner top and inner bottom of the two rectangular grooves 16. U-shaped plates 18 are fixedly connected to both side walls of the conveyor 1. Slide grooves 19 are opened on one inner wall of each of the two U-shaped plates 18. Sliding sliders 20 are slidably connected to the inner walls of the two slide grooves 19. A rack 21 is fixedly connected to the other end of each of the two sliders 20. A connecting block 22 is fixedly connected to the opposite end of each of the two racks 21. A mounting frame 23 is fixedly connected to the opposite end of each of the two connecting blocks 22. Multiple second guide rollers 24 are rotatably connected between the inner top and inner bottom of each of the two mounting frames 23. Through the cooperation of the first guide rollers 17 on the guide plate 15 and the second guide rollers 24 in the mounting frame 23, the packaging box can be guided to maintain the correct position during the conveying process, which facilitates the smooth operation of the fastening operation and reduces the shaking and offset of the packaging box during the conveying process.

[0027] The device comprises two U-shaped plates 18, each with a rotating shaft 25 rotatably connected to its inner walls on both sides. Gears 26 are fixedly connected to the outer walls of both shafts 25, and each gear 26 meshes with a corresponding rack 21. Worm gears 27 are fixedly connected to the outer walls of both shafts 25. Worms 28 are rotatably connected to the inner bottom of both U-shaped plates 18, and each worm gear 28 meshes with a corresponding worm gear 27. Motors 29, both servo motors, are mounted at the lower ends of both U-shaped plates 18. The output shafts of both motors 29 pass through the corresponding U-shaped plates 18 and are fixedly connected to the lower ends of the corresponding worm gears 28. The motors 29 drive the worm gears 28, which in turn drive the worm gears 27 and gears 26, thus moving the rack 21 and related components. This allows the device to automatically adjust the position of the second guide roller 24 according to factors such as the size of the packaging box, adapting to the fastening requirements of different packaging box specifications and enhancing the versatility and flexibility of the device.

[0028] In this utility model, when in use, the motor 29 is started, causing the worm 28 to rotate. Since the worm 28 meshes with the worm wheel 27, the rotation of the worm 28 will drive the worm wheel 27 to rotate, which in turn drives the rotating shaft 25 to rotate. The gear 26 on the rotating shaft 25 will rotate accordingly. Since the gear 26 meshes with the rack 21, the rack 21 will move, which will cause the slider 20 connected to the rack 21 to slide in the slide groove 19. In this way, the position of the mounting frame 23 and the second guide roller 24 can be adjusted, so as to adapt to different specifications of top boxes and bottom boxes.

[0029] Then, the conveyor 1 is started to transport the top box and bottom box placed on it forward. Multiple first guide rollers 17 rotate to guide the position of the top box and bottom box on the conveyor 1 so that they are kept on the appropriate conveying path. At the same time, the second guide rollers 24 on the U-shaped plate 18 play an auxiliary guiding role on the corresponding side of the top box and bottom box, further ensuring the stability of the position of the top box and bottom box during the conveying process.

[0030] Once the top box and bottom box are delivered to the appropriate position, the limiting plate 9 will limit the top box. At this time, the two second electric telescopic rods 11 can be activated to move the two clamping plates 12 until they contact the side wall of the bottom box, thereby limiting the bottom box and ensuring that the top box and bottom box are accurately positioned when they are fastened. Then, the hydraulic cylinder 3 is activated, and its output end drives the lifting plate 4 to move up and down. When the top box needs to be suctioned, the lifting plate 4 descends, the suction mechanism 5 contacts the top box and uses the negative pressure suction cup assembly to suction the top box. Subsequently, the hydraulic cylinder 3 drives the lifting plate 4 to rise, raising the top box to a certain height. Then, the suction mechanism 5 moves the top box above the bottom box for the fastening operation. Finally, the first electric telescopic rod 7 is activated to drive the pressure plate 8 to descend. One side of the pressure plate 8 bends upward, which can apply a certain pressure to the top box and bottom box, so that they are accurately aligned and fastened together. In this way, the fastening operation of the packaging box is realized.

[0031] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
