When the whole die cutting roller 8, the auxiliary roller 9, the upper pressing roller 4 and the lower pressing roller 5 rotate, the rotating disc 34 drives the telescopic frame 33 to expand outwards through the connecting rod 35, so that teeth on the outer side of the rack 31 are meshed with the toothed ring 25 under the driving of the telescopic frame 33, the electric disc 29 is connected with the shell 24 through the rack 31 and the toothed ring 25, then the rotating disc 34 stops moving, the electric disc 29 starts to rotate, the electric disc 29 drives the shell 24 to rotate, and the shell 24 drives the auxiliary disc 10 to rotate together through the auxiliary shaft 13 and the guide rod 14.
The driving box 7 drives the conveying roller 3 to rotate, the limiting rings 6 limit the position of the corrugated board on the conveying roller 3, when the corrugated board passes through the die cutting roller 8 and the auxiliary roller 9, the die cutting roller 8 and the auxiliary roller 9 are matched with each other to die cut the corrugated board, the die-cut corrugated board flows to the upper pressing roller 4 and the lower pressing roller 5, the upper pressing roller 4 and the lower pressing roller 5 are matched with each other to perform indentation treatment on the die-cut corrugated board, and the corrugated board after the indentation treatment is sent into a subsequent forming process through the conveying roller 3.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments.
