[0032] The implementation principle of a packaging box top sealing device of the present application is:

[0033] First, place the packaging box on the conveying platform 1 for conveying. At this time, the rectangular limit plates 2 on both sides above the conveying platform 1 can effectively limit the packaging box. When the packaging box is moved to the bottom of the No. 1 pressing plate 5, one of the four groups of cardboards that need to be folded in the packaging box will complete the folding work, and then start the cylinder 6 inside the connecting block 4. The output end of the cylinder 6 will drive the No. 2 "U"-shaped block 9 to move. The No. 2 "U"-shaped block 9 is connected to the No. 2 pressing plate 8, so that the No. 2 "U"-shaped block 9 drives the No. 2 pressing plate 8 to rotate through the No. 1 "U"-shaped block 7 when it is displaced. At this time, the No. 2 pressing plate 8 will drive the second group of cardboards of the packaging box to complete the folding work.

[0034] Secondly, the bidirectional motor 11 is started, and the bidirectional motor 11 will drive the threaded screws 12 on both sides to rotate. When the threaded screws 12 rotate, they drive the "L"-shaped movable plate 14 to stably move on the horizontal guide rod 13. At this time, the inclined pressing plate 15 under the "L"-shaped movable plate 14 will fold the remaining two groups of cardboards in the packaging box.

[0035] Finally, start the small motor 16, which drives the rotating shaft 17 below to rotate. During the rotation process, the rotating shaft 17 synchronously drives the rotating roller 19 inside the third "U"-shaped block 18 below to change the rotation angle. At this time, the rotating roller 19 will be located above the packaging box, thereby maintaining the stable transportation of the packaging box.

[0036] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application.
