The output ends of the six first hydraulic cylinders 40 are fixedly connected to a connecting frame 41, and three pressing blocks 42 are linearly and fixedly connected to the back side of the connecting frame 41.

[0036] The clamping mechanism 5 includes six second hydraulic cylinders 50. The six second hydraulic cylinders 50 are linearly and fixedly connected to the back side of the left and right fixed plates 11 inside the first housing 1. The output ends of the six second hydraulic cylinders 50 are fixedly connected to four connecting blocks 51. The back of each of the four connecting blocks 51 is slidably connected to a clamping plate 52. A spring 54 is fixedly connected between the clamping plate 52 and the connecting block 51.

[0037] Before the need to form a crease on the outer surface of the paperboard, the paperboard is inserted into the first box 1 from the feeding groove 10, and then the second hydraulic cylinder 50 drives the adapter block 51 to move, the movement of the adapter block 51 drives the clamping plate 52 to move towards the paperboard, the movement of the clamping plate 52 presses the paperboard, and when the clamping plate 52 clamps the paperboard, the spring 54 between the clamping plate 52 and the adapter block 51 forms a buffer between the clamping plate 52 and the adapter block 51, so that the clamping plate 52 can avoid excessive clamping of the paperboard when clamping the outer surface of the paperboard, thereby avoiding leaving marks on the surface of the paperboard by the clamping plate 52, and finally the first hydraulic cylinder 40 drives the connecting frame 41 at the output end to move towards the surface of the paperboard, the movement of the connecting frame 41 drives the pressing block 42 on the back side to move, and the movement of the pressing block 42 presses the outer surface of the paperboard, and the three pressing blocks 42 leave three uniform creases on the outer surface of the paperboard.

[0045] At this time, the servo motor 6 is powered on, the output end of the servo motor 6 drives the threaded rod 60 to rotate, the rotation of the threaded rod 60 drives the outer surface of the first connecting plate 61 to move, the first connecting plate 61 moves to the left side, the movement of the first connecting plate 61 drives the sleeve plate 62 on the right side to rotate around the connecting point of the second box 2, and the sleeve plate 62 is composed of two sleeve plates 62 and is sleeved with each other, in the process of rotating the sleeve plate 62, the two sleeve plates 62 are telescopic, and the rotation of the sleeve plate 62 presses the paperboard to the right side of the connecting cylinder 20 through the crease, and the movement of the first connecting plate 61 drives the second connecting plate 63 on the left side to move, so that the second connecting plate 63 folds the front surface of the paperboard to the front surface of the connecting cylinder 20 through the remaining crease on the outer surface of the paperboard.

[0046] As shown in Figure 10 , Figure 11 and Figure 12 , the left side of the first connecting plate 61 is rotationally connected with the second connecting plate 63, the right side of the arc-shaped plate 64 close to the front position is rotationally connected with three third hydraulic cylinders 65, and the output ends of the three third hydraulic cylinders 65 are all rotationally connected to the left side of the second connecting plate 63 close to the back position.

[0047] Finally, the second connecting plate 63 is driven by the third hydraulic cylinder 65 to rotate, and the second connecting plate 63 presses the remaining part of the paperboard to the left side of the connecting cylinder 20, so that the paperboard is folded into a rectangular cylinder.
