The paper block 315 is guided to fold, and with the cooperation of the pressure plate 322 and the paper guide cavity 311, the cut cardboard is folded into a paper box. Then, the nail box driving member 331 of the nail box assembly 33 drives the stapler 332 and the clamping head 333 to approach each other, and the push piece 336 of the stapler 332 is used to push the staples in the nail guide channel 338, and the staples pass through the paper box and deform under the support of the clamping head 333 to achieve the side edges of the paper box being stapled together to complete the processing of the paper box. Finally, the ejecting driving member 34 ejects the processed paper box out of the paper guide cavity 311 for the transfer mechanism 40 to grab to the unloading mechanism 50, and the unloading mechanism 50 sends the processed paper box out of the frame 10 to realize the automatic folding processing of the paper box.
