[0069] A cartoning method for cardboard packaging boxes, using the cartoning machine described above;

[0070] At least the following steps are included:

[0071] S1. Paper Feeding: Cardboard boxes 4 are stacked or arranged horizontally on the splicing support 11. Wrapping paper 7 is stacked and placed in the paper storage station. The feed module operates, delivering a specified number of cardboard boxes 4 to the feed station 14. The paper feed module 6 operates, and the paper pick-up assembly 62 picks up the wrapping paper 7 at the paper storage station. The paper feed transfer assembly 61 transfers the paper pick-up assembly 62 and the wrapping paper 7 to the splicing station 15, where it is placed on the splicing base. The paper feed transfer assembly 61 drives the paper pick-up assembly 62 out of the splicing station 15.

[0072] S2 wrapping paper: wrapping paper module 2 work, the paper drive assembly 22 drives the paper assembly 21 from the paper splicing station 15 to the feed station 14, at this time the wrapping paper 7 is located below the cardboard box 4, such as Figure 13 In the state shown, during the movement, the wrapping paper sucker 213 always sucks the wrapping paper 7. Figure 14 As shown, the flip driving unit then drives the two flip units 211 to flip upward, and the two ends of the corresponding wrapping paper 7 also flip upward, and the cardboard packaging box 4 is wrapped in the wrapping paper 7. At this time, the two ends of the wrapping paper 7 are higher than the upper end of the cardboard packaging box 4.

[0073] S3. Packing: Figure 14As shown, the packing module 3 is working, and the packing drive assembly 31 drives the paper lifting assembly 32 to move to the feeding station 14. The two paper clamping units work respectively to clamp the corresponding ends of the wrapping paper 7. Then the tightening mechanism 323 works, driving the two paper clamping units to move closer to each other, tightening the wrapping paper 7, and at the same time, the two paper clamping units move horizontally to the area of ​​the cardboard packaging box 4. Immediately afterwards, the packing drive assembly 31 drives the paper lifting assembly 32 to move to the packing station 13, and simultaneously feeds the cardboard packaging box 4 and the wrapping paper 7 into the packaging box 5 located at the packing station 13. The paper clamping unit releases the wrapping paper, and the packing drive assembly 31 drives the paper lifting assembly 32 to exit the packaging box 5, completing a single packing operation.

[0074] Compared to traditional manual packing, the present packing method not only significantly improves efficiency, but also effectively ensures the stability of the cardboard packaging during the transfer and packing process by restraining the cardboard packaging box with the wrapping paper, thus ensuring a high packing success rate. Furthermore, since the wrapping paper remains in the box after packing, in addition to restraining the cardboard packaging box during the packing process, the end of the wrapping paper that engages the paper clamping unit can still be lifted and reversed to remove the cardboard packaging box when it is needed, further improving convenience.

[0075] In short, 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

Wrapping: The wrapping module operates. The wrapping drive assembly drives the splicing assembly from the splicing station to the feeding station. The wrapping paper is now positioned below the cardboard box. The flip drive unit then drives the two flip units to flip upward, flipping the ends of the wrapping paper upward as well. The cardboard box is then wrapped within the wrapping paper. At this point, both ends of the wrapping paper are higher than the top of the cardboard box. S3. Packing: The packing module works, and the packing drive assembly drives the paper lifting assembly to move to the feeding station, and the two paper clamping units work respectively to clamp the corresponding ends of the packaging paper; then the tightening mechanism works to drive the two paper clamping units to approach each other, and the packaging paper is tightened. At the same time, the two paper clamping units move to the cardboard packaging box area in the horizontal direction; then, the packing drive assembly drives the paper lifting assembly to move to the packing station, and simultaneously feeds the cardboard packaging box and packaging paper into the packaging box located at the packing station; the paper clamping unit releases the packaging paper, and the packing drive assembly drives the paper lifting assembly to exit the packaging box, completing a single packing operation.
