[0024] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0025] A packaging box edge-pressing and folding device includes a rear wall folding section, a tail wing folding section 1, a front wall folding section, a top folding section 2, side wing folding sections, a cardboard conveying section 3, and a crossbeam 27 disposed above the cardboard conveying section 3. The tail wing folding section 1 and the top folding section 2 are disposed on the crossbeam 27 and can move horizontally along the crossbeam 27 under the drive of a driving component. Figure 2 As shown, the cardboard to be folded into a carton includes a tail wing 22, a rear wall 21, a bottom surface 25, a front wall 24, a top surface 23, and side wings 26, each part obtained through cutting and creasing processes. After cutting, creasing, and gluing, the cardboard moves along the conveyor path to the cardboard conveyor 3 and continues forward, then undergoes the following steps in sequence: the rear wall folding part raises the rear wall 21 and tail wing 22 together; the tail wing folding part 1 pushes the tail wing 22 to a horizontal position; the front wall folding part raises the front wall 24 and top surface 23 together; and the top surface folding part 2 pushes the top surface 23 to a horizontal position, so that the top surface 23 overlaps and is glued to the tail wing 22. During this process, the side wing folding parts on both sides of the cardboard conveyor 3 fold the side wings 26, thus completing the folding of the entire packaging carton. The rear wall folding part, front wall folding part, side wing folding part, and cardboard conveyor 3 are all existing technologies and will not be described in detail here.

[0026] The tail wing folding section 1 includes a first folding arm 4, one end of which is slidably connected to the crossbeam 27, and the other end is a telescopic end. The telescopic end of the first folding arm 4 is provided with a first suction cup assembly for adhering to the rear wall surface 21 and a first pushing assembly 5 for pushing the tail wing 22. When the rear wall surface 21 and the tail wing 22 are erected together, the first folding arm 4 moves and extends along the cardboard conveying direction, positioning the first suction cup assembly at the position of the rear wall surface 21. Then, the first suction cup assembly adheres to the rear wall surface 21, enhancing its pressure resistance. Finally, the first pushing assembly 5 pushes the tail wing 22 to a horizontal position, thereby preventing the rear wall surface 21 from tilting or deforming.

[0027] The first pressing assembly 5 includes a first pressing rod 6 and a pressing drive assembly for driving the first pressing rod 6 to move. The first pressing rod 6 is a long plate shape, with one end being a free end and the other end connected to the pressing drive assembly. Specifically, two first pressing rods 6 are arranged side by side at intervals. The pressing drive assembly includes a transmission belt 7, which is driven by a transmission wheel driven by a motor. One end of the first pressing rod 6 is connected to the transmission belt 7 and moves back and forth with it. Specifically, the first pressing rod 6 is also connected to a guide assembly, which includes a guide rod 8 and a guide seat 9 sleeved on the guide rod 8. The guide rod 8 is fixedly located at the end of the first folding arm 4, and the guide seat 9 is connected to the end of the first pressing rod 6. After the first suction cup assembly sucks up the rear wall surface 21, the first pressing rod 6 moves along the cardboard conveying direction, pushing the tail wing 22 to a horizontal position.

[0028] The first suction cup assembly includes a Bernoulli suction cup 18 and a vacuum suction cup 19. Specifically, the first suction cup assembly includes a Bernoulli suction cup 18 and two vacuum suction cups 19 located on both sides of the Bernoulli suction cup 18. The Bernoulli suction cup 18 is used to attract the rear wall surface 21, and the vacuum suction cups 19 are silicone suction cups used to adhere to and position the rear wall surface 21.

[0029] The top folding section 2 includes a second folding arm 10 and a third folding arm 16. One end of the second folding arm 10 is slidably connected to the crossbeam 27, and the other end is a telescopic end. The telescopic end of the second folding arm 10 is provided with a second suction cup assembly for adhering to the front wall surface 24 and a second pushing assembly 11 for pressing the top surface 23. After the front wall folding section raises the front wall surface 24 and the top surface 23 together, the second folding arm 10 moves toward the carton and extends, so that the second suction cup assembly is positioned on the front wall surface 24. Then, the second suction cup assembly adheres to the front wall surface 24, enhancing its pressure resistance. Finally, the second pushing assembly 11 pushes the top surface 23 to a horizontal position and attaches it to the tail wing 22, thereby preventing the front wall surface 24 from tilting or deforming.

[0030] The second pressing assembly 11 includes a pressing plate 12, a second pressing rod 13, and a box-holding rod 14. The pressing plate 12 is flat and can move up and down relative to the second folding arm 10 under the drive of a cylinder. The second pressing rod 13 is a long plate with one end free and the other end fixedly connected to the end of the second folding arm 10. Specifically, there are two second pressing rods 13, respectively located on both sides of the pressing plate 12. One end of the box-holding rod 14 is hinged to the second folding arm 10, and the other end is equipped with a roller 15. The box-holding rod 14 can move along the top surface 23 to the rear wall surface 21 via the roller 15. Specifically, there are two box-holding rods 14, respectively located on the outer sides of the two second pressing rods 13.

[0031] The second suction cup assembly is configured in the same way as the first suction cup assembly, both including a Bernoulli suction cup 18 and two vacuum suction cups 19 located on both sides of the Bernoulli suction cup 18. The first suction cup assembly and the second suction cup assembly are arranged opposite to each other. The second suction cup assembly can move along the suction cup slide rail 20, which is located at the end of the second folding arm 10.

[0032] The third folding arm 16 is fixedly mounted on the frame, and its end is provided with a pressure plate 17 that can be raised and lowered relative to it. There are two pressure plates 17, which are respectively located on the outside of the two second push rods 13.

[0033] After the front wall folding section raises the front wall 24 and top wall 23 together, the second folding arm 10 moves relative to the carton. The box-holding rod 14 is pushed to the top wall 23 to a horizontal position by the roller 15, and then moves along the top wall 23 to its edge and then along the rear wall 21 to a position perpendicular to the second push rod 13. At the same time, the telescopic end of the second folding arm 10 extends, so that the second suction cup assembly is in the position of the front wall 24 and the second suction cup assembly moves along the suction cup slide rail 20 to suck up the front wall 24. The extension of the second folding arm 10 also drives the push plate 12 and the second push rod 13 to move downward to press down on the top wall 23. The push plate 12 continues to descend under the drive of the cylinder, so that the top wall 23 and the tail wing 22 are tightly attached. At this time, the carton is confined within the space enclosed by the box-holding rod 14, the push plate 12, the second push rod 13, and the second suction cup assembly. The pressing plate 17 extends downward under the drive of the cylinder, pressing down on the corner 28 where the top surface 23 and the tail wing 22 are attached, preventing the corner from curling up.

[0034] 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.
