As shown in fig. 1, the left and right sides and the front side of the flow channel are fixed with the arc plates 3, the piston rods of the arc plate driving cylinders 8 extend out to drive the movable arc plates 9 to rotate, so that the movable arc plates 9 rotate to the upper side of the flow channel, at this time, a rectangular space is enclosed by all the arc plates 3 and the movable arc plates 9, and the pressing plate 22 is located right above the rectangular space.

The flat sheet is attracted to the platen 22. the platen 22 is connected to a vacuum generator which causes suction holes in the platen 22 to create a negative suction force. After the pressing plate 22 sucks the paper board, the piston rod of the lifting cylinder 21 drives the paper board to move downwards. The cardboard is moved down and continues to move down when being moved down to the rectangle space department that the arc 3 and the activity arc 9 enclose, and the paddle of the cardboard left and right sides is buckled by the 3 jack-ups of the arc of the left and right sides this moment, and the paddle of cardboard front side is bent by the 3 jack-ups of the arc of runner front side, and the paddle of cardboard rear side is buckled by the 9 jack-ups of activity arc, and the paddle laminating at cardboard center is on clamp plate 22, is sent into in the rectangle space that the arc 3 and the activity arc 9 enclose to laminate on the belt of carton transport mechanism 7. Thus, the four front, rear, left and right blades of the paper board are all bent to be vertical to the central blade. Finally, the platen 22 releases the sheet and moves up to reset.

As shown in FIG. 3, after the cardboard is initially folded into a box, the piston rod of the first suction cup driving cylinder 40 extends out and drives the first suction cup 49 to extend forward and be attached to the front side leaf of the cardboard box. The first suction cup 49 is connected to a vacuum generator which causes the first suction cup 49 to generate a negative pressure suction. The piston rod of the first elbow driving cylinder 48 extends out and drives the first elbow 47 to extend towards the carton, so that the first elbow 47 abuts against the front side leaf of the carton.

The first rear cylinder 45 and the first front cylinder 46 drive the first L-shaped plate 41 to move horizontally, the first rear cylinder 45 can drive the first front cylinder 46 and the first L-shaped plate 41 to move horizontally, and the first front cylinder 46 drives the first L-shaped plate 41 to move horizontally.

As shown in fig. 2, after the carton is conveyed to a certain position, the piston rod of the suction cup driving cylinder two 69 extends out and drives the suction cup two 68 to move forward, so that the suction cup two 68 adsorbs the rear leaf of the carton, the suction cup two 68 is connected with the vacuum generator, and the vacuum generator enables the suction cup two 68 to generate negative pressure suction. The rear cylinder III 65 and the front cylinder III 66 drive the bent pipe III 67 and the L-shaped plate III 61 to move forwards horizontally until the bent pipe III 67 abuts against the rear leaf of the carton. The rear cylinder III 65 can drive the front cylinder III 66, the elbow pipe III 67 and the L-shaped plate III 61 to move forwards and horizontally, and the front cylinder III 66 can drive the elbow pipe III 67 and the L-shaped plate III 61 to move forwards and horizontally.
