[0002] In modern industrial production and logistics operations, packaging turnover boxes serve as key carriers in the storage, transportation, and circulation of products. They are widely used in many industries such as food and beverage, electronics, and auto parts. With the continuous expansion of production scale in various industries and the gradual improvement of logistics efficiency requirements, higher standards have been put forward for the handling of packaging turnover boxes, especially their stacking process.

[0003] Traditional packaging material turnover box stacking methods mainly rely on manual operation. Workers must carry and stack the turnover boxes one by one to a designated height. This process is not only labor-intensive but also extremely inefficient. Even when simple mechanical equipment is introduced to assist in stacking, many drawbacks remain. Some simple devices can only achieve basic lifting functions and perform poorly in terms of precise positioning of turnover boxes, control of stacking order, and adaptability to turnover boxes of different sizes. When faced with packaging material turnover boxes of different sizes, shapes, or weights, these devices often cannot be adjusted flexibly, frequently resulting in uneven stacking and boxes slipping, seriously affecting the safety of goods storage and space utilization. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an automatic stacking device for packaging turnover boxes, which can be applied to the stacking of turnover boxes of different sizes and improve work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic stacking device for packaging turnover boxes includes a conveyor belt for transporting turnover boxes. Gantry frames are installed on both the left and right sides of the conveyor belt. An adjustment assembly is commonly installed on the top of the gantry frames. A base is fixedly connected to the opposite side of the lower end of each gantry frame. Limit rods are fixedly connected to the front and rear ends of both the gantry frames and the bases.

A first servo motor is fixedly connected to the top of the gantry frame, and the drive end of the first servo motor is fixedly connected to the top of the lead screw.

[0006] Furthermore, a pressure plate that moves up and down is provided on the upper outer side of the limiting rod, and a spring is provided on the upper outer side of the limiting rod above the pressure plate.

[0007] Furthermore, a top rod is fixedly connected to the upper end of the clamping plate, and a protective pad is fixedly connected to the outer side of the clamping plate.

[0008] Furthermore, the base is provided with an up-and-down movable mounting plate, and both the front and rear ends of the mounting plate are rotatably connected to rollers.

[0009] Furthermore, movable plates are provided at both the front and rear ends of the base, the lower end of the movable plate is fixedly connected to the upper side of the mounting plate, and a pad is fixedly connected to the top of the movable plate.

[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of an automatic stacking device for packaging turnover boxes, including a conveyor belt 1 for conveying turnover boxes. Gantry frames 2 are provided on both the left and right sides of the conveyor belt 1. An adjustment assembly is provided on the top of the gantry frames 2. A base 3 is fixedly connected to the opposite side of the lower end of each gantry frame 2. Limit rods 4 are fixedly connected to the front and rear ends of both the gantry frames 2 and the base 3. A sliding lifting plate 5 is provided outside the limit rods 4. A movable rod 6 is movably connected to the opposite end of each lifting plate 5. A clamping plate 7 is fixedly connected to the end of each movable rod 6. An electric push rod 10 is fixedly connected to the lower side of the lifting plate 5. The driving end of the electric push rod 10 is fixedly connected to the outside of the clamping plate 7. A lead screw 13 is threadedly connected to the middle of the lifting plate 5. The lead screw 13... Both ends are rotatably connected to the inside of the gantry 2 and the base 3 respectively. The top of the gantry 2 is fixedly connected to the first servo motor 14. The drive end of the first servo motor 14 is fixedly connected to the top of the lead screw 13. The upper end of the limit rod 4 is provided with a vertically movable pressure plate 11. The upper end of the limit rod 4 is provided with a spring 12 located on the upper side of the pressure plate 11. The upper end of the clamping plate 7 is fixedly connected to the top rod 8. The outer side of the clamping plate 7 is fixedly connected to the protective pad 9. The inside of the base 3 is provided with a vertically movable mounting plate 15. The front and rear ends of the mounting plate 15 are rotatably connected to rollers 16. The front and rear ends of the base 3 are provided with movable plates 17. The lower end of the movable plate 17 is fixedly connected to the upper side of the mounting plate 15. The top of the movable plate 17 is fixedly connected to the pad 18.

[0019] Before stacking the crates, the equipment must be precisely installed on the outside of conveyor belt 1 to ensure that the equipment is compatible with the operating rhythm of conveyor belt 1, laying the foundation for efficient stacking. When the stacking operation is officially started, the first servo motor 14 is started, and its drive end drives the lead screw 13 to start rotating. Since the lifting plate 5 is threadedly connected to the lead screw 13, and the lifting plate 5 is sleeved on the outside of the limit rod 4, the rotating lead screw 13 will drive the lifting plate 5 to descend smoothly along the limit rod 4. The limit rod 4 plays a key guiding and balancing role. This effectively prevents the lifting plate 5 from shifting or swaying during its descent. As the lifting plate 5 descends, its opposite movable rod 6 and the clamping plate 7 connected to the end of the movable rod 6 also move down synchronously until the clamping plate 7 is positioned precisely on the left and right sides of the stacked turnover boxes on the conveyor belt 1. At this point, the electric push rod 10 is activated, and its drive end pushes the clamping plate 7 closer to the turnover box. Because the outer side of the clamping plate 7 is fixed with a protective pad 9, during the clamping process, it can firmly clamp the turnover box to prevent it from slipping, and also avoid direct contact between the clamping plate 7 and the turnover box, preventing damage to the box. The system effectively protects against damage. After the clamping plate 7 stably holds the turnover box, the first servo motor 14 rotates in the reverse direction, driving the lead screw 13 to rotate in the reverse direction. This causes the lifting plate 5 to move upward along the limit rod 4, and the clamped turnover box is smoothly lifted. While the turnover box is being lifted, the conveyor belt 1 accurately transports the next turnover box to be stacked directly below the equipment, achieving seamless connection between the upper and lower processes and greatly improving overall work efficiency. Subsequently, the first servo motor 14 rotates in the forward direction again, and the lifting plate 5 drives the already... The clamped turnover box descends, allowing the upper turnover box to be precisely stacked on top of the turnover box on the lower conveyor belt 1. As the turnover boxes are continuously stacked, the stacking height gradually increases. When the top of the turnover box contacts the pressure plate 11, it will push the pressure plate 11 to move upward along the limit rod 4. The spring 12 located on the upper side of the pressure plate 11 is compressed, and the reaction force generated by the spring 12 will make the pressure plate 11 press tightly on the uppermost turnover box, effectively ensuring the stability of the turnover box during the stacking process, preventing it from tipping over or shifting, and improving the safety of stacking.

[0020] Reference Figure 1 and Figure 4 The upper end of the gantry 2 is provided with a housing 19. The housing 19 is provided with a gear 23. The upper side of the housing 19 is fixedly connected to a second servo motor 22. The drive end of the second servo motor 22 is fixedly connected to the middle of the gear 23. The upper end of the gantry 2 is fixedly connected to a toothed plate 24 on the opposite side. The opposite side of the toothed plate 24 is respectively meshed with the front and rear sides of the gear 23. Limiting grooves 20 are provided at both the front and rear ends of the upper side of the housing 19. A slider 21 is slidably connected to the inner side of the limiting groove 20. The lower end of the slider 21 is fixedly connected to the top of the gantry 2.

[0021] When handling turnover boxes of different sizes, the equipment can activate the second servo motor 22, which drives the gear 23 inside the housing 19 to rotate. Since the front and rear sides of the gear 23 mesh with the toothed plates 24 on opposite sides of the upper end of the gantry 2, the rotation of the gear 23 will cause the two toothed plates 24 to move in opposite directions, thereby causing the gantry 2 on both sides to move towards or away from each other within the housing 19. At the same time, the slider 21 on the top of the gantry 2 slides within the limiting groove 20 on the upper side of the housing 19, providing guidance and limiting for the movement of the gantry 2. The positioning ensures the smoothness of the adjustment process and allows for precise changes in the distance between the two clamping plates 7, thus meeting the stacking requirements of turnover boxes of different sizes and shapes, and enhancing the versatility and adaptability of the equipment. When the equipment needs to be moved to adjust the working position, the first servo motor 14 is activated to drive the lead screw 13 to rotate, causing the lifting plate 5 to continuously descend and press against the pad 18. After the pad 18 is under pressure, the force is transmitted to the mounting plate 15 through the movable plate 17, causing the mounting plate 15 to drive the rollers 16 at both ends to move downward relative to the base 3. Once the rollers 16 contact the ground and support the entire equipment, the equipment can be easily moved by pushing it through the rollers 16, greatly improving the flexibility and ease of movement of the equipment, and facilitating rapid adjustment of the working position according to changes in the production layout.

[0022] Working Principle: Before stacking the turnover boxes, the device is installed on the outside of the conveyor belt 1. During stacking, the first servo motor 14 is activated, driving the lead screw 13 to rotate. The rotating lead screw 13 drives the lifting plate 5 to descend. The descending lifting plate 5 is balanced by the limit rod 4. As the lifting plate 5 descends, it drives the clamping plates 7 to be placed on the left and right sides of the turnover box. The electric push rod 10 is activated, driving the clamping plates 7 to approach the turnover box and clamp the turnover box from both sides. Then, the first servo motor 14 rotates in the opposite direction, driving the lifting plate 5 to rise, thereby driving the turnover box to rise. The conveyor belt 1 moves the next turnover box to directly below the device. Then, the lifting plate 5 drives the turnover box to descend, and stacking continues. The turnover boxes are continuously stacked, and the height of the turnover boxes is adjusted accordingly. As the stacking mechanism continues to increase, its top contacts the pressure plate 11 and compresses the spring 12. The reaction force of the spring 12 causes the pressure plate 11 to press against the turnover box, maintaining the stability of the turnover box. The second servo motor 22, which is set to start, drives the gear 23 to rotate. Through the cooperation of the gear 23 and the toothed plate 24, the gantry frame 2 located on both sides can be moved to both sides to adjust the distance between the two clamping plates 7, thus making it suitable for stacking turnover boxes of different sizes. When it is necessary to move the device, the first servo motor 14 drives the lead screw 13 to rotate, so that the lifting plate 5 presses against the pad 18, and the mounting plate 15 and the roller 16 move downward relative to the base 3 and the gantry frame 2, contacting the ground and supporting the device. The device can be moved by the roller 16.
