[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] Please see Figures 1-4A convenient food packaging box production capping device includes a first base 1, a first conveying device 3, a second base 2, a second conveying device 4, a feeding and capping device, and a guiding device. The first conveying device 3 is installed inside the first base 1, and the second conveying device 4 is installed inside the second base 2. The first base 1 is lower than the second base 2, and the first base 1 and the second base 2 are in staggered perpendicular contact. The feeding and capping device is installed directly above the first base 1 and the second base 2. The feeding and capping device includes a fixing frame 5, a rectangular groove 6, a threaded rod 7, a slider 8, a drive motor 9, an electric telescopic rod 10, a vacuum pump 11, a mounting base 12, a transmission pipe 13, and an annular groove 14. The annular tube 15 and the suction base 16 are provided. The top of the first base 1 and the second base 2 are mounted on the fixing frame 5 via support columns. A rectangular groove 6 is formed below the fixing frame 5. A threaded rod 7 is rotatably mounted in the rectangular groove 6. One end of the threaded rod 7 passes through the rectangular groove 6 and is mounted on the drive motor 9. The threaded rod 7 is threadedly mounted on the slider 8. An electric telescopic rod 10 is fixedly mounted on the bottom wall of the slider 8. The bottom output end of the electric telescopic rod 10 is mounted on the mounting base 12. A vacuum pump 11 is mounted on the top wall of the fixing frame 5. A transmission pipe 13 is mounted on one side wall of the vacuum pump 11. A circular groove 14 is formed on the bottom wall of the mounting base 12. A drive motor 9 is installed in the circular groove 14. The annular tube 15 is connected to the end of the transmission tube 13 through the side wall of the mounting base 12. Multiple sets of suction seats 16 are installed in a ring shape on the bottom wall of the annular tube 15. The guide device is installed at one end of the first base 1. In this embodiment, during use, the parameters of each electronic component are first set by the control system. The first conveying device 3 on the first base 1 conveys the food packaging box (both the first conveying device 3 and the second conveying device 4 are well-known technologies in this field and will not be described in detail here). The second conveying device 4 on the second base 2 conveys the box cover. The first motor starts, and the output end of the first motor drives the threaded rod 7 to rotate. During the rotation, the threaded rod 7 drives the slider 8 to move linearly from above the first conveying device 3 to the first... Above the second conveyor device 4, the electric telescopic rod 10 drives the mounting base 12 to descend. The box cover, which is being conveyed to the end of the second base 2 above the second conveyor device 4, is then activated. The vacuum pump 11 extracts air through the transmission pipe 13, creating negative pressure in the suction seat 16 within the annular pipe 15, thus adsorbing a box cover. At this point, the box cover is firmly fixed to the suction seat 16, i.e., the bottom of the mounting base 12, ready for the capping operation. Then, the drive motor 9 is activated in reverse, moving the mounting base 12 and the adsorbed box cover above the first conveyor device 3. When the food packaging box is conveyed below the mounting base 12 via the first conveyor device 3 through the guide device, the electric telescopic rod 10 responds, extending its output end downwards.The mounting base 12, with the lid attached, is precisely aligned with the opening of the packaging box and pressed down. Then, the vacuum pump 11 releases the suction from the lid, completing the lid-pressing operation of the food packaging box.
[0025] In practical use, the food packaging box is further guided and limited. In this embodiment, the guiding device includes a fixed plate 17, a cylinder 18, and a guide plate 19. Two sets of fixed plates 17 are symmetrically installed at one end of the first base 1. The cylinder 18 is installed on the outer wall of both sets of fixed plates 17. The output end of both sets of cylinders 18 passes through the fixed plate 17 and is installed with the guide plate 19. When the food packaging box is conveyed into the two sets of guide plates 19 by the first conveying device 3, the cylinder 18 starts to move. The output end of the cylinder 18 gradually extends, pushing the guide plate 19 to move inward, forming a gradually narrowing channel. As the cylinder 18 extends, the guide plate 19 gradually approaches the sides of the packaging box, ensuring that the packaging box always maintains the correct direction and position during the conveying process. The design of the guide plate 19 can be finely adjusted according to the size of the packaging box to adapt to different specifications of packaging boxes. Since the position of the guide plate 19 can be precisely controlled by the cylinder 18, it can be ensured that each packaging box enters the capping area in the same way, avoiding the risk of displacement or tipping over.
[0026] In practical use, to further facilitate the storage of the guide plate 19, in this embodiment, the fixed plate 17 has a square groove 20 at one end near the guide plate 19. The square groove 20 is adapted to the guide plate 19. When no guiding and limiting operation is required, the guide plate 19 can be completely stored in the square groove 20 in the fixed plate 17 by the retraction action of the cylinder 18. This design allows the guide plate 19 to be completely hidden inside the fixed plate 17, avoiding the occupation of additional space.
[0027] In actual use, to further prevent the guide plate 19 from damaging the packaging box, in this embodiment, the corners of the two sets of guide plates 19 that are close to each other are rounded. The rounded corner design can effectively reduce the direct contact area between the guide plate 19 and the side wall of the packaging box, and avoid sharp corners from causing scratches, indentations or damage to the surface of the packaging box. Especially when the packaging box material is thin or has a coating, the rounded corner design can better protect the integrity of the packaging box and ensure the appearance quality of the product.
[0028] In actual use, the transmission pipe 13 is further guided. In this embodiment, a guide ring 21 is installed on the side wall of the fixing frame 5, and the transmission pipe 13 is movably installed in the guide ring 21. Since the transmission pipe 13 is fixed and guided by the guide ring 21, it reduces obvious shaking or swaying during operation, reduces the impact on other components (such as electric telescopic rod 10, slider 8, etc.), and ensures the overall stability of the equipment.
[0029] In actual use, the slider 8 is further guided. In this embodiment, two sets of guide rods 22 are symmetrically installed in the rectangular groove 6 with the central axis of the threaded rod 7. Both sets of guide rods 22 are slidably connected to the slider 8. The design of the guide rods 22 can effectively limit the lateral movement of the slider 8 and ensure that it always moves in a straight line along the central axis of the threaded rod 7. This not only improves the accuracy of the movement of the slider 8, but also avoids the problem of inaccurate pressure cap position caused by the offset of the slider 8.
[0030] In practical use, to further ensure the stability and accuracy of the drive motor 9, in this embodiment, the drive motor 9 is a servo motor. The servo motor has a built-in encoder or sensor, which can monitor the position and speed of the motor in real time and feed this information back to the control system. Through closed-loop control, the servo motor can achieve extremely high position accuracy, ensuring that the slider 8 can accurately reach the designated position every time. This is especially important for capping operations that require high-precision positioning, and can significantly improve the success rate of capping and the sealing quality.
[0031] In actual use, the lid is further limited to prevent it from falling. In this embodiment, a limiting plate 23 is installed at one end of the second base 2 near the first base 1. The design of the limiting plate 23 can effectively prevent the lid from falling accidentally during the conveying process. Since the first base 1 is higher than the second base 2 and the two are in staggered vertical contact, the lid may loosen or even fall off due to gravity or vibration. The presence of the limiting plate 23 can ensure that the lid is always in the correct position at the end of the first conveying device 3, avoiding the risk of falling.
