The frame 1 is provided with a plurality of first sliding guide rods 11 perpendicular to the conveying direction of the conveyor belt 2, the cutting frame 31 is penetrated on the plurality of first sliding guide rods 11 and has a supporting surface 311 flush with the conveying surface of the conveyor belt 2, the A locking screw 312 is threadedly connected to the cutting frame 31 and is tightly pressed against the first sliding guide rod 11. The traction chain 32 is arranged in the cutting frame 31 and is parallel to the conveying direction of the conveyor belt 2 and is connected to the driving motor 17. A toggle block 321 that can be exposed on the supporting surface 311 is fixedly connected to the traction chain 32. The cutting motor 34 is arranged on the cutting frame 31. The cutting saw blade 33 is fixedly connected to the output shaft of the cutting motor 34 and is located in the cutting frame 31. The cutting saw blade 33 partially passes through the through groove provided on the supporting surface 311.
[0022] In the above embodiment, the support surface 311 is connected with the conveying surface of the conveyor belt 2, and the cardboard to be cut placed on the conveyor belt 2 is transferred to the support surface 311 as the conveyor belt 2 is transported toward the cutting seat. Then, the traction chain 32 driven by the driving motor 17 drives the toggle block 321 to abut against the rear end of the cardboard and drives the cardboard to move toward the cutting saw blade 33 on the support surface 311. The cutting saw blade 33 driven by the cutting motor 34 to rotate completes the cutting of the cardboard during the movement of the cardboard on the support surface 311. The cutting is completed. The cutting frame 31 is moved to move the cutting block 321 to leave the supporting surface 311 to unload the material. When the distance between the plurality of cutting mechanisms 3 (i.e. the distance between the plurality of cutting saw blades 33) needs to be adjusted to meet the cutting requirements of different sizes, the locking screw 312 is loosened, the cutting frame 31 is moved to slide into place on the first sliding guide rod 11, and then the locking screw 312 is tightened. The adjustment is very convenient and quick, so that the cutting device can cut the cardboard into cardboards of different sizes through one cutting, which has better applicability.
[0023] Preferably, in order to facilitate the position adjustment of the cutting mechanism 3, a first driving rod 35 perpendicular to the first sliding guide rod 11 is rotatably provided on the cutting frame 31, and a first gear 36 is fixedly connected to each of the two ends of the first driving rod 35. Two first racks 37 respectively located under the two first gears 36 and meshing with the first gears 36 are provided on the frame 1. A first handle 38 is fixedly connected to the end of the first driving rod 35. After loosening the locking screw 312, the first driving rod 35 is rotated by the first handle 38 to drive the first gear 36 to rotate, and the cutting frame 31 is driven to slide on the first sliding guide rod 11 with the cooperation of the first rack 37, thereby making the position adjustment of the cutting mechanism 3 more convenient and accurate.

When the cardboard is moved on the supporting surface 311 by the shifting block 321 and is cut by the cutting saw blade 33, the pressing plate 42 cooperates with the supporting surface 311 to impose a longitudinal limit on the cardboard, thereby ensuring the stability of the cardboard when moving on the supporting surface 311 and preventing the cardboard from jumping when being cut by the cutting saw blade 33, thereby ensuring the accuracy of the cutting saw blade 33 when cutting the cardboard, so that the incision remains flat. While the distance between the plurality of cutting mechanisms 3 is adjusted by driving the cutting frame 31 to slide on the first sliding guide rod 11, the distance between the plurality of pressing mechanisms 4 is adjusted by driving the sliding frame 41 to slide on the second sliding guide rod 12, so that the distance between the plurality of pressing mechanisms 4 matches the distance between the plurality of cutting structures, and the pressing plate 42 is kept above the supporting surface 311 and located on one side of the cutting saw blade 33 to impose a limit on the cardboard in cooperation with the supporting surface 311.
[0026] Preferably, in order to facilitate the position adjustment of the pressing structure, a second driving rod 43 perpendicular to the second sliding guide rod 12 is rotatably provided on the sliding frame 41, and a second gear 44 is fixedly connected to each of the two ends of the second driving rod 43.

[0028] In the above preferred embodiment, the height of the pressing mechanism 4 can be adjusted by rotating the adjusting screw 14 through the third handle 15 to drive the lifting frame 45 to slide on the third sliding guide rail, thereby adjusting the height difference between the pressing plate 42 and the supporting surface 311, so that the height difference between the pressing plate 42 and the supporting surface 311 can match cardboards of different thicknesses, thereby having better applicability.
[0029] Preferably, the same cutting mechanism 3 has two traction chains 32 symmetrically arranged along the cutting saw blade 33, and the same pressing mechanism 4 has two pressing plates 42 symmetrically arranged along the cutting saw blade 33, to ensure that the positions of the cardboard on both sides of the cutting saw blade 33 can be moved by the moving block 321 and limited by the pressing plate 42 during the cutting process of the cardboard being cut by the cutting saw blade 33, thereby enhancing the stability of the cardboard when it is moved and cut by the cutting saw blade 33, and ensuring the flatness of the incision.
[0030] Preferably, a transmission shaft 16 that is transmission-connected to a driving motor 17 is rotatably provided on the frame 1, and a keyway is provided on the transmission shaft 16 along its length direction. The sprocket of the traction chain 32 is rotatably provided in the cutting frame 31 and is loosely keyed to the transmission shaft 16, so that the sprocket of the traction chain 32 can slide on the transmission shaft 16 while the cutting frame 31 slides on the first sliding guide rod 11, so as to cooperate with the sliding of the cutting frame 31 to realize the position adjustment of the cutting mechanism 3, and the transmission shaft 16 can simultaneously drive the traction chains 32 of several cutting mechanisms 3 to move after being driven by the driving motor 17, thereby ensuring the synchronization of the traction chains 32 of several cutting mechanisms 3 when driving the cardboard to move through the toggle block 321, thereby ensuring the stability of the cardboard when it moves on the supporting surface 311, and also ensuring the flatness of the cutting saw blade 33 when cutting the cardboard.
