[0032] Furthermore, the frame 1 is provided with a movable frame 12 along the conveying direction. The movable frame 12 is connected to a movable frame drive device 121 and a second sealing device 110. A connecting bracket 13 is symmetrically slidably arranged on the movable frame 12. A guide wheel 14 is connected to the connecting bracket 13. A connecting bracket drive device 131 is connected to the connecting bracket 13.
[0033] Furthermore, the movable frame 12 is provided with a guide rod 15 at one end facing the folding frame 3, and the guide rod 15 has an arc-shaped segment.
[0034] Furthermore, a first limiting plate 16 is symmetrically arranged below the folding frame 3, and a second driving device is connected to the first limiting plate 16.

[0035] Furthermore, a second limiting plate 17 is symmetrically arranged below the moving frame 12. The second limiting plate 17 is connected to a third driving device. The third driving device is used to drive the two second limiting plates 17 to move closer to or further away from the conveying mechanism 10.
[0036] The working principle of this utility model is as follows:
[0037] The operator first moves carton 2 onto the conveyor mechanism 10, then arranges the two lids at the top of carton 2 so that they are close together. Figure 1 As shown. When the carton 2 is conveyed to the bottom of the folding frame 3, the first drive device 5 drives the folding frame 3 to move downward. An arc-shaped bracket 31 is connected to the folding frame 3, and a pressure rod 32 is connected to the arc-shaped bracket 31. The arc-shaped bracket drive device 33 drives the arc-shaped bracket 31 to swing relative to the folding frame 3 until they are close to each other, so that the two pressure rods 32 on the arc-shaped bracket 31 press against one end of the left and right carton lids respectively. Under the force of the pressure rods 32, the two carton lids are folded to close the opening of the carton. Then, the lid-pressing arm 4 swings around the bearing 6 under the action of the drive cylinder 7, and finally drives the lower end of the lid-pressing arm 4 to abut against the other end of the carton lid. When the lid-pressing arm 4 is in the position of the folding frame 3, the folding frame 31 moves downward. Figure 1In the structure shown, the two sides of the capping arm 4 abut against the left and right box covers respectively. Through the cooperation of the capping arm 4 and the pressure rod 32, the left and right box covers can be folded to close the opening of the box and maintained in a closed state. In order to increase the performance of this folding machine, a first sealing device 11 is provided on the frame 1 located below the folding frame 3. After the carton 2 is placed on the conveying mechanism 10, during the conveying process, while the first sealing device 11 seals the left and right box covers at the bottom of the carton 2, the capping arm 4 and the pressure rod 32 simultaneously fold the left and right box covers at the top of the carton 2, thereby improving work efficiency.
[0038] Based on the above technical solution, the structural cooperation between the capping arm 4 and the folding frame 3 can be as follows: a bearing 6 is provided on the folding frame 3, the capping arm 4 is rotatably mounted on the bearing 6, and a telescopic cylinder is provided on the folding frame 3 to drive the capping arm 4 to rotate relative to the folding frame 3.
[0039] As the carton 2 moves below the folding frame 3, not only is the upper lid folded, but the lower lid is also sealed. As the carton 2 continues to move along the conveyor mechanism 10, it reaches the area below the moving frame 12. At this point, the moving frame 12, driven by the moving frame drive device 121, moves the guide rod 15 downwards. The guide rod 15 then abuts against the left and right lids at the top of the carton 2. As the carton 2 continues to move along the conveyor mechanism 10, the second sealing device 110 on the moving frame 12 seals the left and right lids at the top of the carton 2. In this technical solution, the guide rod 15 has an arc-shaped section. This arc-shaped section allows the guide rod 15 to abut against the upper lid of the carton 2 when it moves below the moving frame 12, facilitating the sealing operation of the upper lid by the second sealing device 110 on the moving frame 12.
[0040] Based on the above technical solution, this application provides guide wheels 14 movably arranged on both sides of the movable frame 12. A connecting bracket 13 corresponding to the guide wheels 14 is slidably arranged on the movable frame 12. A connecting bracket driving device 131 is connected to the connecting bracket 13. Under the drive of the connecting bracket driving device 131, the connecting bracket 13 drives the two guide wheels 14 to move closer or further away from each other. When the carton 2 moves under the movable frame 12, the guide wheels 14 move and abut against both sides of the carton 2. This design restricts the movement trajectory of the carton 2, allowing the second sealing device 110 to better seal the lid of the carton 2.
[0041] Throughout the process, this application provides first limiting plates 16 on both sides of the conveying mechanism 10 located below the folding frame 3. A second driving device is connected to each first limiting plate 16, driving the two first limiting plates 16 to move closer or further apart. The function of the first limiting plates 16 is to form a first channel for the movement of the cardboard box 2, guiding its trajectory and allowing it to move directly below the folding frame 3. When the cardboard box 2 moves out from below the folding frame 3, this application provides second limiting plates 17 on both sides of the conveying mechanism 10 located below the moving frame 12. The two second limiting plates 17 form a second channel for the movement of the cardboard box 2. As the cardboard box 2 moves within the first channel, when one end of the cardboard box 2 moves out of the first channel and is located below the moving frame 12, a third driving device drives the second limiting plates 17 to move closer together, causing them to adhere to the outside of the cardboard box 2. At this time, the two second limiting plates 17 together form a second channel. A second channel is formed, which guides the movement trajectory of the carton 2. As the conveyor mechanism 10 continues to convey the carton 2, the carton 2 moves within the second channel. The moving frame 12 moves downward and the guide rod 15 abuts against the lid at the top of the carton 2, keeping the lid closed. As the carton 2 moves forward, the second sealing device 110 on the moving frame 12 seals the lid at the top of the carton 2. After the sealing process is completed, the carton 2 continues to move along the second channel to the designated position. The second and third driving devices mentioned above can both be implemented using a driving cylinder; the first driving device 5 and the moving frame driving device 121 mentioned above can be implemented using a chain conveyor; the arc-shaped support driving device 33 mentioned above can be implemented using a driving cylinder. The design principle of the driving devices mentioned above is a mature technical means in this field and is not the main design concept of this application, so it will not be described in detail here.
[0042] As an example 1, the conveying mechanism 10 described above can be implemented by a roller conveyor. Since roller conveyors are a mature technology in this field, they will not be described in detail here.
[0043] This application features a folding frame that slides on the frame, and a capping arm that rotates on the folding frame. The combined structure of the folding frame and the capping arm allows the left and right carton lids to be folded to close the opening of the carton, thus replacing manual folding and improving work efficiency. In addition, this application includes a first sealing device on the frame and a second sealing device on the movable frame 12. Therefore, this folding machine can not only fold cartons but also seal them.
[0044] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
