[0002] In the modern packaging industry, composite packaging paperboard is widely used due to its excellent mechanical properties and environmental adaptability. This type of paperboard, through a combination of multiple layers of materials with different properties, provides excellent protection, ensuring product safety during transportation and storage. As market demands for packaging quality increase, composite packaging paperboard with higher compressive strength and better moisture resistance has become an inevitable trend in the industry.

[0003] Existing composite packaging paperboard pressing equipment often only achieves single-point or linear contact pressing, which may lead to insufficient bonding between the layers of the composite packaging paperboard, especially in the edge areas where delamination is prone to occur, affecting the quality and durability of the final product. In addition, this pressing method may also result in uneven pressure distribution, with some areas having excessive pressure and others insufficient pressure, thereby weakening the overall compressive strength of the paperboard and failing to fully guarantee the integrity of the internal moisture-proof layer, thus reducing the moisture-proof effect. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-position pressing device for pressure-resistant and moisture-proof composite packaging paperboard, so as to solve the problems mentioned in the background art of uneven pressure distribution, easy delamination at the edges, and inability to fully guarantee the integrity of the moisture-proof layer in current composite packaging paperboard pressing equipment.

[0008] Preferably, the top of the outer end of the swing plate is provided with an arc-shaped guide block, and the outer end of the bottom groove of the dynamic auxiliary seat is provided with an arc-shaped guide seat that cooperates with the structure of the arc-shaped guide block.

[0009] Preferably, the rotating circular plate has a strip-shaped notch inside and a drive block is symmetrically arranged through a linear guide rail, and the bottom of the drive block is fixedly connected to the corresponding pressing unit mechanism.

[0010] Preferably, the strip-shaped recess inside the rotating circular plate is provided with a supporting guide post, and the driving block is sleeved on the outside of the supporting guide post through a through hole.

[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] Please see Figure 1-4This utility model provides a technical solution: a multi-position pressing device for pressure-resistant and moisture-proof composite packaging paperboard, including a processing table 1. Side frames 2 are welded and fixed to both sides of the top of the processing table 1. A lifting frame 3 is driven between the side frames 2 via a vertical guide rail. A main base 4 is welded and fixed to the middle of the bottom of the lifting frame 3 via a connector. The main base 4 has a rectangular structure. A rotating circular plate 6 is connected to the main base 4 via a rotator 5. The output end of the rotator 5 is fixedly connected to the center of the top of the rotating circular plate 6. Both sides of the main base 4 are provided with laterally movable dynamic auxiliary seats 7. Both sides of the bottom of the dynamic auxiliary seats 7 are provided with swing plates 8 via grooves. The bottom of the outer end of the swing plates 8 and the bottom of the rotating circular plate 6 are provided with independently adjustable pressing unit mechanisms 9. Composed of an actuator cylinder 91, a pressure head 92, and a pressure sensor 93, the processing table 1 serves as the foundation of the entire device, supporting the composite packaging cardboard to be pressed. The side frame 2 guides the lifting frame 3 to move up and down via a vertical guide rail. When the lifting frame 3 descends, the main base 4, fixed in the middle of its bottom, moves closer to the cardboard on the processing table 1. The main base 4 can be driven by a rotator 5 to rotate the rotating disc 6, adjusting the angle as needed to ensure flexibility and adaptability during the pressing process. Simultaneously, the dynamic auxiliary seats 7 on both sides of the main base 4 can move horizontally to accommodate cardboard of different sizes. After reaching the designated position, the swing plate 8 further adjusts its posture accordingly, activating the pressing unit mechanism 9. The actuator cylinder 91 drives the pressure head 92 downward. The system applies pressure to the cardboard, while the integrated pressure sensor 93 monitors and provides real-time feedback on the pressure value, ensuring precise pressure control. Overall, this multi-position pressing method allows each layer of material to bond tightly under uniform and moderate pressure, avoiding insufficient bonding force and edge delamination problems caused by traditional single-point or linear pressing. Furthermore, the more uniform pressure distribution not only enhances the overall compressive strength of the cardboard but also protects the integrity of the internal moisture-proof layer, effectively solving the problems of uneven pressure, easy edge delamination, and reduced moisture-proof performance in existing technologies. This significantly improves the product's quality and durability. The main base 4 has telescopic grooves on both sides that match the structure of the dynamic auxiliary seat 7, and the inner end of the dynamic auxiliary seat 7 extends movably into... Within the telescopic groove on the side of the main base 4, and on both sides of the top of the main base 4, a push cylinder 10 is fixedly installed via a bracket. The output end of the push cylinder 10 is fixedly connected to the top of the dynamic auxiliary seat 7 via a connecting block. When the position needs to be adjusted, the push cylinder 10 is activated, allowing its output end to precisely control the movement of the dynamic auxiliary seat 7. As the push cylinder 10 extends and retracts, the dynamic auxiliary seat 7 can slide smoothly within the telescopic groove, ensuring stability and accuracy during displacement. This linkage mechanism not only improves the equipment's adaptability to different specifications of cardboard but also ensures the consistency and reliability of the pressing operation, ultimately achieving a more uniform pressure distribution, enhancing the bonding strength between the layers of the composite packaging cardboard, and simplifying the operation process.This design improves work efficiency. A servo motor 11 is fixed to the top of the inner end of the dynamic auxiliary seat 7 via a top fixing bolt. The output shaft of the servo motor 11 is fixedly connected to the top of the inner end of the swing plate 8. When the servo motor 11 starts, it can drive the swing plate 8 to precisely swing between the two bottom corners of the dynamic auxiliary seat 7 via the output shaft. This ensures that the swing plate 8 can flexibly change position according to the specific shape and size requirements of the cardboard, achieving effective pressing of the edge areas of cardboard of different shapes and ensuring uniform pressure distribution during the pressing process. An arc-shaped guide block 15 is welded and fixed to the top of the outer end of the swing plate 8, and an arc-shaped guide seat 14 that matches the structure of the arc-shaped guide block 15 is welded and fixed to the outer end of the bottom groove of the dynamic auxiliary seat 7. When the servo motor 11 drives the swing plate 8 to swing and adjust, the arc-shaped guide block 15 slides along the inside of the arc-shaped guide seat 14, ensuring that the movement of the swing plate 8 at the bottom of the dynamic auxiliary seat 7 is both smooth and even. The smooth and precise design not only provides a stable guiding path for the swing plate 8 but also limits its swing range, preventing positional deviations or equipment damage caused by excessive swinging. The rotating circular plate 6 has a strip-shaped notch inside and symmetrically arranged drive blocks 12 via linear guides. The bottom of the drive blocks 12 is fixedly connected to the corresponding pressing unit mechanism 9. This structure allows the drive blocks 12 to move laterally at the bottom of the rotating circular plate 6 via the linear guides. This enables the two sets of pressing unit mechanisms 9 at the bottom of the rotating circular plate 6 to achieve multi-position pressing, accurately performing pressing operations at different positions. The strip-shaped notch inside the rotating circular plate 6 provides a support guide post 13, and the drive blocks 12 are sleeved on the outside of the support guide post 13 through through holes. This structure, with the support guide post 13 serving as a guiding and supporting element, ensures that the drive blocks 12 move smoothly and precisely along the linear guides, preventing deviation or shaking during pressing and enhancing the stability of the entire structure.

[0019] Working Principle: When using this multi-position pressing device for pressure-resistant and moisture-proof composite packaging paperboard, the composite packaging paperboard to be pressed is first placed on the processing table 1. Then, the side frame 2 guides the lifting frame 3 downward through the vertical guide rail, so that the main base 4 is close to the paperboard on the processing table 1. At this time, according to the specific size and shape requirements of the paperboard, the push cylinder 10 is activated, and its output end precisely controls the movement of the dynamic auxiliary seat 7. The dynamic auxiliary seat 7 slides smoothly to the designated position in the telescopic groove inside the main base 4. Subsequently, the servo motor 11 is started, and the output shaft drives the swing plate 8 to make precise swing adjustments. The swing plate 8 synchronously drives the arc-shaped guide block 15 to slide along the inside of the arc-shaped guide seat 14. The movement of the oscillating plate 8 is smooth and precise. Meanwhile, the rotating plate 6, driven by the rotator 5, can adjust its angle as needed to adapt to different pressing requirements. After all components are adjusted, the pressing unit mechanism 9 located at the bottom of the outer end of the oscillating plate 8 and the bottom of the rotating plate 6 begins to work. The actuator cylinder 91 drives the pressure head 92 to move downward to apply pressure to the cardboard, while the integrated pressure sensor 93 monitors and feeds back the pressure value in real time to ensure precise pressure control. At the same time, the drive block 12 and the support guide column 13 at the bottom of the rotating plate 6 cooperate with each other to drive the corresponding pressing unit mechanism 9 to accurately perform pressing operations at different positions, thereby completing a series of tasks.

[0020] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
