[0108] When in use, under the limiting action of the flipping guide groove D11, the connecting slide arm D5 of the flipping mechanism D will drive the picked-up cardboard to flip, specifically to take the cardboard out from the cardboard bin C and then put it into the packaging box.

[0109] Working principle: The worker places the packaging box on the packaging box conveyor E. Then, the flipping mechanism D operates, lifting the suction and folding mechanism A and aligning it with the cardboard hopper C. Under the operation of the flipping mechanism D, the cardboard is removed and transported into the packaging box. During transport, the moving mechanism B and the suction and folding assembly work simultaneously to fold the flat cardboard into… Figure 6 As the middle pad is folded, the flipping mechanism D transports the pad to the top of the packaging box, and then places the pad at the bottom of the packaging box. After placement, the packaging box continues to be transported forward a distance by the conveyor mechanism, and the next packaging box enters the loading position. The above steps are repeated to carry out the operation.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
