[0038] In this embodiment, a laser locator 19 is installed on the frame 1 .

[0039] In this embodiment, the specific cardboard feeding process is as follows:

[0040] When it is necessary to convey cardboard with a larger width, the single cardboard conveying mode is switched to push the multiple mounting plates 222 to swing downward 90 degrees, so that the first guide strip 221 is flipped downward 90 degrees, so that the side of the first guide strip 221 faces upward and is flush with the top surface of the supporting block 224. At this time, the cardboard is input by the rolling of the multiple feed rollers 112, so that the cardboard passes through the multiple first guide strips 221 and the supporting block 224 in sequence, and is supported and conveyed by the first limiting roller 13, and then conveyed between the two second limiting rollers 15, and finally output to the paper stack through the top of the third limiting roller 18.

[0041] When one or more cardboards with smaller width specifications need to be conveyed, the multiple mounting plates 222 are pushed to swing upward 90°, so that the first guide strip 221 is turned upward 90°, so that the side surface of the first guide strip 221 faces left or right and is perpendicular to the top surface of the supporting block 224. At this time, the cardboard is input by the rolling of the multiple feed rollers 112, so that the cardboard enters between the two first sliding seats 22 of the same pair, and is supported and conveyed by the two first sliding seats 22 and the second sliding seat 23 between the two first sliding seats 22. Then, it is pressed down by the first limiting pressure roller 13, and the discharge end of the first sliding seat 22 and the discharge end of the supporting block 225 are bent downward to guide it to enter the material connection section 31. Then, it is pressed down by the second limiting pressure roller 15 located at the lower side, so that the cardboard climbs upward through the climbing section 32, and finally is pressed down by the third limiting pressure roller 18 to be output to the paper stack.

[0042] In this mode, when the cardboard needs to be stopped, the piston rod of the second lifting cylinder 223 is controlled to extend to push the paper pressing block 225 to move downward, pressing the cardboard against the first sliding seat 22 to stop the cardboard from moving.

[0043] When two layers of cardboard need to be conveyed up and down, the multiple mounting plates 222 are pushed to swing downward 90°, causing the first guide strips 221 to flip downward 90°, so that the side surfaces of the first guide strips 221 face upward and are flush with the top surface of the supporting block 224. Then, the upper layer of cardboard is supported and conveyed by the multiple first guide strips 221 and the supporting block 224, and the lower layer of cardboard is conveyed by the two first sliding seats 22 and the second sliding seat 23 between the two first sliding seats 22, thereby achieving synchronous conveyance of the two layers of cardboard.

[0044] In this embodiment, the first sliding seat 22 and the second sliding seat 23 are locked and fixed on the adjustment rail 21 by screws.

[0045] In this embodiment, the stability of paper stack loading is ensured by the roller 17 guide and the positioning roller 161 at both ends of the frame 1. A laser positioner 19 and multiple feed rollers 112 are installed on the frame 1 to monitor and control the cardboard feeding rhythm in real time, thereby realizing full automation of cardboard feeding. The dual paper storage feeding method is used, which occupies a small area and is extremely efficient, greatly reducing production costs.
