[0027] 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.

[0028] Reference Figures 1-3This utility model provides an embodiment of a tablecloth sealing device, including an outer frame 1. The outer frame 1 serves as the support frame for the entire device, providing an installation foundation and structural protection for each component. A sealing machine 2 is fixedly connected to the top of the inner wall of the outer frame 1. The sealing machine 2 is used to automatically seal cartons conveyed below it, completing the final sealing process for tablecloth packaging. A transmission platform 3 is fixedly connected to the inner wall of the outer frame 1. The transmission platform 3 is the main platform for conveying cartons and is responsible for conveying cartons to be sealed. A receiving platform 4 is hinged to the left side of the transmission platform 3 through a limiting component. The receiving platform 4 can receive cartons to be sealed. Its hinged design with the transmission platform 3 allows for angle adjustment according to actual needs. The limiting component is used to fix the position of the receiving platform 4. Transmission rollers 5 are rotatably connected to the inner walls of both the transmission platform 3 and the receiving platform 4. The transmission rollers 5 convey cartons by rotating. Several sets of transmission rollers 5... The configuration ensures the smoothness of the carton conveying process. Several sets of transmission rollers 5 are provided, and each set of transmission rollers 5 is fixedly connected to a pulley 13 at its end. The synchronous rotation of the pulleys 13 can drive the transmission rollers 5 to work together, ensuring that the rotation speed of each transmission roller 5 is consistent. The several sets of pulleys 13 are connected by transmission belts 14, which play the role of transmitting power, so that power can be transmitted from one pulley 13 to all other pulleys 13. A motor 15 is fixedly connected to the center of the rightmost set of pulleys 13. The motor 15 provides the power source for the entire transmission system and drives the pulleys 13 to rotate. The pulleys 13 are rotatably connected to the inner wall of the transmission table 3, and the motor 15 is fixedly connected to the right inner wall of the transmission table 3.

[0029] Reference Figures 2-5The limiting component includes a limiting frame 22, which serves as the outer shell of the limiting component, providing installation space and protection for internal parts. The limiting frame 22 is fixedly connected to the end of the transmission table 3, allowing the limiting component to stably engage with the transmission table 3. A gear 6 is rotatably connected to the inner wall of the limiting frame 22. The rotation of gear 6 can drive the hinge shaft of the receiving table 4 to rotate, thereby adjusting the angle of the receiving table 4. A gear 7 meshes with the inner side of the outer wall of gear 6. The meshing relationship between gear 7 and gear 6 can transmit the rotation of gear 6 and also serve as a limiting function. A guide block 9 is elastically connected to the inner wall of gear 7 through a limiting spring 8. The limiting spring 8 provides elastic force to the guide block 9, allowing the guide block 9 to reset under external force. The guide block 9 is square, allowing it to slide on the inner wall of gear 7 and also drive gear 7 to rotate. A limiting rod 10 is fixedly connected to the outer end of the guide block 9. The movement of the guide block 9 can drive the limiting rod 10. Synchronous movement enables the extension and retraction of the limiting rod 10. A limiting block 11 is fixedly connected to the outer arc surface of the limiting rod 10. The limiting block 11 is a key component for limiting, achieving positional fixation through cooperation with the limiting groove 12. The outer wall of the limiting frame 22 has several sets of limiting grooves 12, providing engagement positions for the limiting blocks 11. Different limiting grooves 12 correspond to the receiving platform 4. At different angles, gear 6 is fixedly connected to the bottom hinge shaft of the receiving platform 4, gear 7 is rotatably connected to the inner wall of the limiting frame 22, one end of the limiting spring 8 is fixedly connected to the inner wall of gear 7, and the other end of the limiting spring 8 is fixedly connected to the end of the guide block 9. Through the opposing pressing force between the limiting spring 8 and gear 7, the limiting block 11 is always locked on the inner wall of the limiting groove 12 without being affected by external force. The guide block 9 is slidably connected to the inner wall of gear 7, the limiting rod 10 is slidably connected to the inner wall of the limiting frame 22, and the limiting block 11 is locked on the inner wall of the limiting groove 12.

[0030] Reference Figure 1 , Figure 2 , Figure 5A guide plate 16 is fixedly connected to the top of the inner wall of the outer frame 1. The guide plate 16 provides an installation carrier for the guide structure and guides the movement of the connecting rod 19. A counter-threaded rod 17 is rotatably connected to the bottom inner wall of the guide plate 16. The rotation of the counter-threaded rod 17 can drive the connecting rods 19 on both sides to move in opposite directions, thereby adjusting the spacing between the guide wheels 21. A motor 18 is fixedly connected to the right end of the counter-threaded rod 17. The motor 18 provides power for the rotation of the counter-threaded rod 17. By controlling the forward and reverse rotation of the motor 18, the direction of the counter-threaded rod 17 can be controlled. A connecting rod 19 is threadedly connected to the outer wall of the counter-threaded rod 17. The connecting rod 19 converts the rotational motion of the counter-threaded rod 17 into linear motion, driving the guide frame 20 to move. A guide frame 20 is fixedly connected to the bottom of the connecting rod 19. The guide frame 20 provides installation support for the guide wheel 21, allowing the guide wheel 21 to move. The guide frame 20 is rotatably connected to the inner wall of the guide frame 20. The guide wheel 21 is used to contact the carton and guide it during the carton conveying process, reducing the offset of the carton and keeping the carton in the center when conveyed to the bottom of the sealing machine 2. This ensures that the sealing machine 2 can accurately seal the carton and improve the sealing quality. The top inner wall of the connecting rod 19 is slidably connected to the outer wall of the guide plate 16. The motor 18 is fixedly connected to the outer wall of the outer frame 1. The bottom of the guide frame 20 is in contact with the top of the transmission table 3.

[0031] Working principle: Before starting the equipment, the angle of the receiving platform 4 is adjusted according to the size of the carton to be sealed and the conveying requirements through the limiting components. During operation, the limiting rod 10 is pulled outward, which drives the guide block 9 to compress the limiting spring 8, causing the limiting block 11 to disengage from the limiting groove 12 on the outer wall of the limiting frame 22, thus releasing the limiting of gear 7. Then, the receiving platform 4 is rotated, and its bottom hinge shaft drives gear 6 to rotate. Gear 6 meshes with and drives gear 7 to rotate synchronously. When the receiving platform 4 is adjusted to the appropriate angle, the limiting rod 10 is released, and the limiting spring 8 returns to its original position, pushing the guide block 9 and the limiting rod 10 back, so that the limiting block 11 is engaged in the corresponding limiting groove 12, thus completing the angle fixing of the receiving platform 4.

[0032] When sealing the carton, place the carton containing the tablecloth on the receiving platform 4 and start motor 15. Motor 15 drives the rightmost set of pulleys 13 to rotate, and through the transmission belt 14, drives several sets of pulleys 13 to rotate synchronously, thereby causing the transmission platform 3 and several sets of transmission rollers 5 on the inner wall of the receiving platform 4 to rotate in tandem. The rotating transmission rollers 5 generate friction, smoothly conveying the carton on the receiving platform 4 to the transmission platform 3 for subsequent guiding processes. Depending on the width of the carton, start motor 218 to control the rotation of the opposing threaded rod 17. Since the top inner wall of the connecting rod 19 is slidably connected to the outer wall of the guide plate 16, the rotational motion of the opposing threaded rod 17 is converted into the linear motion of the connecting rod 19, causing the connecting rods 19 on both sides to drive the guide frame 20 to move in opposite directions until the guide wheel 21 on the inner wall of the guide frame 20 is in contact with the sides of the carton. As the cartons are conveyed along the conveyor table 3, guide wheels 21 limit and guide the cartons, effectively reducing their offset and ensuring they remain centered as they are conveyed downwards to the sealing machine 2. When the centered cartons reach the bottom of the sealing machine 2, which is fixedly connected to the top of the inner wall of the outer frame 1, the sealing machine 2 starts and automatically seals the cartons, completing the final sealing process for the tablecloth packaging. After sealing, the cartons continue to be conveyed away from the sealing machine 2 area by the drive rollers 5 and are finally output from the conveyor table 3, thus automating the entire tablecloth sealing process.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
