[0002] In modern logistics and commodity circulation systems, corrugated cardboard boxes, as one of the most widely used packaging containers, play a crucial role in ensuring product transportation safety and improving packaging efficiency through efficient, precise, and reliable sealing operations. With the continuous expansion of production scale across industries and the increasing market demand for rapid turnover, improving sealing efficiency is essential to meet the needs of large-scale production.

[0003] As shown in the prior art of CN220465945U, although this prior art uses the rotation of a motor to drive two sliders to move closer or further apart, simultaneously moving two clamping plates closer or further apart, and when the carton is clamped between a rotating disc mounted on the clamping plates, the user can rotate the carton after one end is sealed with tape, causing the other side of the carton to flip upwards, thus facilitating the tape to seal the other open end of the carton, allowing the carton clamped in the device to be sealed quickly and efficiently. However, this prior art requires operating the handle to rotate the carton first, and then operating the tape to seal the carton, resulting in discontinuous operation and affecting sealing efficiency. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a sealing device for corrugated cardboard boxes. By pressing down on the pedal, the connecting plate is pushed down, causing the connecting plate to push the movable plate and two linkage plates outward. The toothed plate on the linkage plate then drives the gear, which in turn drives the linkage shaft to rotate the positioning frame, thereby turning the cardboard box to the front. The pedal is then lifted by the spring rebound, and the movable plate and linkage plates are reset by the connecting plate. Finally, the positioning frame is reset by the meshing of the toothed plate and gear. In this way, the box turning and sealing operations can be performed by using both hands and feet, improving the sealing efficiency and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for corrugated cardboard boxes, including a base, the top of which is provided with a positioning component for fixing the cardboard box, and the cardboard box can be flipped over by an adjusting component outside the positioning component;

[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. 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.

[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a sealing device for corrugated cardboard boxes, including a base 1. The top of the base 1 is provided with a positioning component for fixing the cardboard box, and the cardboard box can be flipped over by an adjusting component outside the positioning component. The adjusting component includes a movable plate 2 located at the top front end of the base 1. A through hole 3 is opened on the outside of the top end of the movable plate 2. A positioning post 4 is installed inside the through hole 3. Both ends of the positioning post 4 are fitted with linkage plates 5. A toothed plate 6 is installed at the top rear end of the linkage plate 5. A linkage shaft 7 is provided at the top of the toothed plate 6, and a gear 8 that meshes with the toothed plate 6 is fitted on the outside of the linkage shaft 7. A pedal 9 is provided on the rear side of the movable plate 2, and telescopic rods 10 for connecting the base 1 are installed at the bottom of both ends of the pedal 9. A spring 11 is fitted on the outside of the top end of the telescopic rod 10. A connecting plate 12 is rotatably connected between the pedal 9 and the movable plate 2.

[0025] When using the above equipment, the staff places the cardboard box on the positioning component, which then fixes the cardboard box in place. The positioning component includes a groove 13 on the top of the base 1. An adjusting rod 14 is installed inside the groove 13 and is movably connected to it via a bearing. Both ends of the adjusting rod 14 are threaded to movable plates 15. On the side of the two movable plates 15 that are close to each other, a positioning frame 16 is installed and is movably connected to it via a rotating shaft. The positioning frame 16 has an L-shaped cross-section, and a servo motor 17 for driving the adjusting rod 14 is installed on one side of the rear end of the base 1. The end of the linkage shaft 7 away from the gear 8 passes through the movable plate 15 and is fixed together with the rotating shaft on the positioning frame 16.

[0026] In this way, the servo motor 17 can drive the adjusting rod 14 to rotate, and the adjusting rod 14 can then drive the two moving plates 15 to move inward synchronously. The two moving plates 15 can then drive the corresponding positioning frame 16 to fix the carton, thereby facilitating the positioning of cartons of different specifications and improving the practicality of this utility model.

[0027] Since the bottom cross-section of the movable plate 15 and the cross-section of the groove 13 are both rectangular, and the outer bottom of the movable plate 15 is in contact with the inner wall of the groove 13, the groove 13 can limit the movable plate 15, thereby ensuring the stability of the movable plate 15 when it is moved and preventing the movable plate 15 from tilting during the movement.

[0028] The linkage plate 5 has a connecting hole 18 on its rear exterior, and a T-shaped connecting plate 19 is provided inside the connecting hole 18. The end of the connecting plate 19 away from the linkage plate 5 is fixed to the moving plate 15. This allows the connecting plate 19 to engage with the connecting hole 18, thereby causing the linkage plate 5 to move with the moving plate 15, thus maintaining the linkage between the adjusting component and the positioning component.

[0029] At the same time, the staff steps on the pedal 9 to move it down. The pedal 9 presses down on the connecting plate 12, and the connecting plate 12 pushes the movable plate 2 to move outward. The movable plate 2 then moves outward along with the two linkage plates 5. The toothed plate 6 on the linkage plate 5 then drives the gear 8. The gear 8 drives the linkage shaft 7 to rotate the positioning frame 16, so that the carton can be rotated in both directions, achieving the effect of conveniently flipping the carton.

[0030] After the pressing is finished, the spring 11 lifts the pedal 9 to reset. The pedal 9 then moves the movable plate 2 inward through the connecting plate 12. The movable plate 2 then drives the toothed plate 6 on the linkage plate 5 to move. The gear 8 drives the positioning frame 16 to rotate through the gear 8 and the linkage shaft 7, thereby driving the carton to reset. In this way, the sealing operation of the carton can be completed.

[0031] After flipping the cardboard box, the staff needs to use tape to seal the box. Therefore, a housing 20 is installed at the top rear end of the base 1. Two vertical plates 21 are installed at the bottom of the top of the housing 20. A screw 22 is installed between the two vertical plates 21 and is movably connected by a bearing. The screw 22 is externally threaded to a screw seat 23. An electric push rod 24 is installed at the bottom of the screw seat 23, and an installation shell 25 for assembling tape is installed at the bottom of the electric push rod 24. A drive motor 26 is installed on the side of one of the vertical plates 21 away from the screw 22. The output shaft of the drive motor 26 passes through the vertical plate 21 and is fixed together with the screw 22.

[0032] In this way, the electric push rod 24 can be used to move the mounting shell 25 down, so that the tape inside the mounting shell 25 comes into contact with the carton. Then the drive motor 26 drives the screw 22 to rotate, and the screw 22 drives the screw seat 23 to move back and forth, so as to facilitate the tape to be attached to the outside of the carton, thereby completing the sealing operation of the carton.

[0033] To ensure the stability of the screw seat 23 during displacement, a limiting rod 27 is provided at the top of the screw 22. The front and rear ends of the limiting rod 27 are fixed to the two vertical plates 21 respectively, and the top of the screw seat 23 is sleeved on the outside of the limiting rod 27. In this way, the limiting rod 27 can limit the screw seat 23, preventing the screw seat 23 from shifting during the displacement process and ensuring the stability of the screw seat 23 during displacement.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
