[0026] Reference Figures 1 and 2 , is an embodiment of the present utility model, and proposes

[0027] A cardboard edge sealing device, comprising:

[0028] A rack 1 having a plurality of mounting slots 2;

[0029] There are several coating rollers 3, each of which is rotatably arranged on the frame 1 and is used to apply edge sealing oil to the cardboard;

[0030] There are several conveying rollers 4, and several of the conveying rollers 4 are rotatably arranged in the mounting groove 2, and several of the conveying rollers 4 are evenly distributed on one side of the coating roller 3, and several of the conveying rollers 4 are tilted in the mounting groove 2, and the conveying rollers 4 are used to convey the cardboard;

[0031] The turning device 5 is provided on the frame 1 and is located at both ends of the frame 1. The turning device 5 is used to turn the cardboard.

[0032] In this embodiment, the rotation setting of the coating roller 3 and the conveying roller 4 automates the cardboard edge sealing process, greatly improving production efficiency and reducing labor costs and time costs. The setting of the coating roller 3 ensures that the edge sealing oil can be evenly applied to the edge of the cardboard, avoiding the unevenness and overflow problems that may occur in manual operation. The inclined arrangement and uniform distribution of the conveying roller 4 help to stabilize the position of the cardboard during the transportation process and reduce the edge sealing quality problems caused by the unstable movement of the cardboard. The design of the flipping device 5 allows the cardboard to be flipped during the edge sealing process, making double-sided edge sealing possible, increasing the use scenarios and application range of the cardboard, and by being tilted on the conveying roller 4, the cardboard can be moved closer to the direction of the coating roller 3 during the transportation process, thereby avoiding the problem of cheap transportation, so that the edge sealing can be more uniform and beautiful during the edge sealing process.

[0033] Optionally, the coating rollers 3 are arranged in two rows, and a plurality of conveying rollers 4 are provided on one side of the two rows of coating rollers 3 .

[0034] In this embodiment, the coating rollers 3 of this solution have two rows, and the two rows of coating rollers 3 have two rows. The two rows of coating rollers 3 can realize double-station edge sealing at the same time, thereby improving the efficiency of edge sealing.

[0035] Optionally, the frame 1 is provided with a plurality of avoidance grooves 6, and the turning device 5 includes:

[0036] There are several rotating disks 7, which are rotatably arranged on the frame 1, and the rotating disk 7 is located on one side of the frame 1 along the cardboard conveying direction. The rotating disk 7 has several clamping grooves 8, and the several clamping grooves 8 are arranged along the circumference of the rotating disk 7, and the rotating disk 7 is located in the avoidance groove 6. After the cardboard moves on the conveying roller 4 on one side, it slides into the clamping groove 8. The rotating disk 7 is used to convey the cardboard to the conveying roller 4 on the other side.

[0037] In this embodiment, the design of the rotating disk 7 enables faster and more accurate cardboard flipping, reducing time consumption during the flipping process and improving overall production efficiency. The snap-in slots 8 are arranged along the circumference of the rotating disk 7, ensuring accurate positioning of the cardboard during flipping and reducing edge sealing quality issues caused by inaccurate positioning. During transport, the cardboard slides into the snap-in slots 8, preventing hard contact with the machine during flipping and minimizing damage to the cardboard edges. The design of the escape slots 6 allows the rotating disk 7 to be hidden within the frame 1 when not in use, saving space while ensuring the neatness and operational safety of the equipment. The rotating disk 7 can be adjusted as needed to accommodate cardboards of varying sizes and shapes, increasing the flexibility and applicability of the equipment. After the cardboard moves over the conveyor rollers 4 on one side, it automatically slides into the snap-in slots 8, simplifying the operation process and reducing operator workload. After the cardboard is flipped and conveyed by the rotating disk 7, the edge sealing can be performed on the other side, greatly enhancing the automation of the equipment and improving edge sealing efficiency.

[0038] Optionally, the two rows of conveying rollers 4 respectively form a first conveying end 9 and a second conveying end 10, further comprising:

[0039] The second rotating member 11 is swingably arranged on the frame 1, and the swing angle of the second rotating member 11 is 180°. The second rotating member 11 is located at one end away from the rotating disk 7. The second rotating member 11 has a supporting end 12. After the second rotating member 11 rotates, the supporting end 12 is used to communicate with the first conveying end 9 or the second conveying end 10.

[0040] In this embodiment, by setting the second rotating member 11, the cardboard can be flexibly switched between the first conveying end 9 and the second conveying end 10, thereby enhancing the dual-end conveying capacity of the equipment. The second rotating member 11 can swing 180°, providing two different cardboard conveying paths, so that the operator can select the most suitable conveying end according to actual production needs. The fast switching capability of the second rotating member 11 makes the conversion of cardboard between the two conveying ends faster, reduces the pause time in the production process, and improves the overall production efficiency. The design of the second rotating member 11 allows the cardboard to be conveyed at both ends without adding additional space, optimizing the utilization of production space. The setting of the second rotating member 11 reduces the need for additional conveying equipment, simplifies the structure of the entire edge sealing device, and reduces the complexity of the equipment. Moreover, by cooperating with the second rotating member 11 and the rotating disk 7, the adjustment of the four sides of the cardboard can be further realized, thereby achieving fully automatic edge sealing of the four side walls of the square cardboard, thereby improving production efficiency.

[0041] Optionally, the second rotating member 11 has an abutting end 13, and the abutting end 13 is used to abut the paperboard.

[0042] In this embodiment, the arrangement of the abutting end 13 improves the conveying accuracy of the second rotating member 11 and also avoids damage to the cardboard.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
