A sliding groove extending along the height direction of the fixed vertical rod 904 is provided on the inner side of the fixed vertical rod 904 for limiting, and the connection method between the screw sleeve 907 and the sliding groove is a sliding connection.

[0035] The working process of the present invention is as follows: the signal sending setting of the infrared distance detection sensor 307 is performed in advance, and the time required for the paperboard to continue to be conveyed to the position where the indentation line of the paperboard is located directly above the indentation line guide rod 502 after the infrared distance detection sensor 307 detects the position of the indentation line of the paperboard is measured, and after the setting is completed, the folding plate is started to be folded and pressed;

[0036] Place the rectangular cardboard on the top of the conveyor platform 3, and drive the leftmost active conveyor roller 302 to rotate through the driving motor 305. Under the cooperation of the driving pulley 303 and the driving belt 304, multiple sets of active conveyor rollers 302 start to rotate, and the cardboard is driven to move slowly from left to right with the assistance of the driven transmission roller 301. When one end of the cardboard passes through the bottom of the folding frame 306 and the indentation line is detected by the infrared distance detection sensor 307, a signal is sent to the controller after the set time is reached, and the controller stops the driving motor 305 to drive the cardboard to continue moving. At this time, the side of the cardboard extending out of the conveyor platform 3 is naturally laid flat on the top of the folding plate 808, and then the cardboard is started. The forward and reverse motor 905 drives the rotating screw 906 to rotate, so that the thread drives the screw sleeve 907 to move up and down, and the paper pressing plate 903 moves down under the sliding cooperation of the guide bar 902 and the paper pressing plate 903 to fix the side of the cardboard in a certain area. Next, the driving end of the driving cylinder 5 moves down to drive the creasing line guide rod 502 to abut against the creasing line to position the cardboard to avoid deviation during folding. Finally, the electric push rod 803 starts to drive the sliding guide plate 805 to slide with the sliding track 804, so that the rack 806 is meshed with the gear 807, and finally drives the rotating shaft 801 to rotate, so that the folding plate 808 drives the cardboard to fold, thereby completing the folding work of the cardboard.
