[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a novel seamless bonding device for cardboard boxes, comprising a seamless bonding device body 1 and a cardboard box 5. A gluing mechanism 6 is installed on the seamless bonding device body 1. A support platform 8 is provided on the seamless bonding device body 1, and a conveyor belt 7 is embedded within the support platform 8. The cardboard box 5 is placed on the conveyor belt 7. A portal frame 2 is connected to the upper end of the support platform 8, and a hydraulic lifting mechanism 3 is connected to the top inner side of the portal frame 2 via a linear transmission structure. The gluing mechanism 6 is fixed to the bottom of the movable end of the hydraulic lifting mechanism 3. Limiting plates 4 and bonding and fastening roller shafts 12 are respectively provided on both sides of the conveyor belt 7. A limiting roller 9 is also provided above the bonding and fastening roller shaft 12. The limiting roller 9 is fixed to a U-shaped roller frame 901 via a rotating rod. A telescopic rod 902 is provided between the gantry frame 1 and the portal frame 2, and both ends of the telescopic rod 902 are screwed to the roller frame 901 and the portal frame 2 respectively. This structure uses a rubber limiting roller 9, which guides the adhesive fixing folding plate 502 when the carton 5 is conveyed by the conveyor belt 7. The limiting roller 9 and the adhesive fixing folding plate 502 can form an adsorption effect, ensuring that the adhesive fixing folding plate 502 and the carton 5 have an acute angle, exposing the glue application area 501. After the glue application area 501 is completed, the adhesive fixing folding plate 502 can be quickly folded and glued. The telescopic rod 902 is an existing self-locking telescopic structure. By adjusting the length of the telescopic rod 902, the position of the limiting roller 9 can be controlled, thereby... The limiting roller 9 better guides the adhesive fixing folding plate 502, and the limiting roller 9 is set at an angle. The limiting plate 4 is a folding plate structure, and the limiting plate 4 is movably engaged with the support platform 8. A linear movement mechanism 401 passes through the lower part of the limiting plate 4 and the support platform 8. This structure allows the limiting plate 4 to move linearly. After the carton 5 is moved into place, the movement of the limiting plate 4 is used to align the edges of the carton 5 to ensure accurate glue application. During glue application, the carton 5 is moved again to control the glue application width. The carton 5 is integrally provided with a glue application area 501 and an adhesive fixing folding plate 502 that are bonded together. The glue application area 501 is located below the glue application mechanism 6, and the adhesive fixing folding plate 502 is connected to the limiting roller 9 and the adhesive fixing folding plate 502. The fastening roller shaft 12 is in contact with the support platform 8. A screw lifting mechanism 10 is bolted to the upper end of the support platform 8, and a hydraulic drive cylinder 11 passes through the inner side of the screw lifting mechanism 10. Connecting ears 1101, which are threadedly connected to the screw structure of the screw lifting mechanism 10, are welded to both sides of the hydraulic drive cylinder 11. This structure, through the cooperation of the screw lifting mechanism 10 and the connecting ears 1101, can drive the hydraulic drive cylinder 11 to perform lifting, adjustment, and positioning. This allows the distance between the fastening roller shaft 12 and the support platform 8 to be adjusted according to the specific thickness of the carton 5, so that the fastening roller shaft 12 can better bond and fasten the bonding and fixing plate 502 and the glue application area 501. The hydraulic drive cylinder 11 is horizontally set and is movable through the gantry frame 2.This structure allows the hydraulic drive cylinder 11 to be positioned via the gantry frame 2. While limiting the lifting and lowering of the hydraulic drive cylinder 11, it prevents lateral movement, ensuring the stability of the adhesive fastening roller 12. The movable end of the hydraulic drive cylinder 11 is bolted to the fixed end of the adhesive fastening roller 12, and the adhesive fastening roller 12 is perpendicular to the hydraulic drive cylinder 11. This structure allows the adhesive fastening roller 12 to move linearly under the drive of the hydraulic drive cylinder 11, enabling it to fold the adhesive fixing plate 502 and bond it to the glued area 501. The adhesive fastening roller 12 ensures a tight connection between the adhesive fixing plate 502 and the glued area 501, achieving seamless bonding.

[0018] Working Principle: When using this new seamless cardboard box bonding device, the main body 1 of the seamless bonding device first forms a support and positioning structure through the gantry frame 2 and the support platform 8. The conveyor belt 7 moves under the positioning of the support platform 8. The cardboard box 5 is conveyed by the conveyor belt 7 in a folded state. The glue application area 501 is located at the top, and the bonding and fixing folding plate 502 is set at an angle and guided by the limiting roller 9. By controlling the length of the telescopic rod 902, the distance between the roller frame 901 and the gantry frame 2 can be adjusted, thereby controlling the movement of the limiting roller 9. Positioning allows the limiting roller 9 to guide and adsorb the adhesive fixing folding plate 502, preventing it from folding. When the carton 5 moves below the gluing mechanism 6, the limiting plate 4 moves under the transmission of the linear movement mechanism 401, aligning the edges of the carton 5. Simultaneously, the hydraulic lifting mechanism 3 drives the gluing mechanism 6 downward, pressing the coating area of ​​the gluing mechanism 6 against the edge of the coating area 501. At the same time, the limiting plate 4 moves again under the drive of the linear movement mechanism 401, further pushing the carton 5. The process involves controlling the movement distance of the carton 5 to control the width of the gluing area. After gluing is completed, the hydraulic lifting mechanism 3 drives the gluing mechanism 6 to rise, simultaneously activating the hydraulic drive cylinder 11. The hydraulic drive cylinder 11 pushes the adhesive fastening roller 12 to move. After the adhesive fastening roller 12 contacts the adhesive fixing folding plate 502, it pushes the adhesive fixing folding plate 502. At this time, the adsorption force between the adhesive fixing folding plate 502 and the limiting roller 9 disappears, causing the adhesive fixing folding plate 502 to fold under the action of gravity. The adhesive fastening roller 12 moves to the gluing area... When the adhesive area is 501, the bonding and fixing plate 502 and the adhesive area 501 are firmly bonded together. The connecting ear 1101 is raised and lowered by the screw structure of the screw lifting mechanism 10, which controls the height of the hydraulic drive cylinder 11. This adjusts the distance between the bonding and fixing roller shaft 12 and the support platform 8, allowing the bonding and fixing roller shaft 12 to better bond and fix the plate 502 and the adhesive area 501 together. This achieves high-efficiency seamless bonding and fixing of the carton 5 by the main body 1 of the seamless bonding device, thus completing a series of tasks.

[0019] 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.
