In use, a worker makes the interval between the adjacent two clamping plates 200 identical and adapted to the thickness of the corrugated cardboard 700, then loads a plurality of corrugated cardboards 700 one by one into the gap between the clamping plates 200 and aligns the corrugated cardboards 700, when the upper and lower facial tissues of the corrugated cardboards 700 are all in contact with the upper and lower surfaces of the clamping plates 200, then reciprocates the saw blade 300 in the feed slot 210 in the vertical direction, then pushes the corrugated cardboards 700 to move horizontally leftwards, when the saw blade 300 moves upwards from below and the saw blade 320 approaches the upper facial tissues of the corrugated cardboards 700, the guide 400 drives the saw blade 320 to move to the right limit position, when the tooth edge of the saw blade 320 is positioned right below the upper facial tissues of the corrugated cardboards 700, as the saw blade 300 continues to move vertically upwards, the tooth edge of the saw blade 320 is in contact with the upper facial tissues of the corrugated cardboards 700 and cuts the upper facial tissues of the corrugated cardboards 700, it will be appreciated that although the upper sheet of corrugated cardboard 700 is subjected to a relatively large upward force from the saw teeth 320 at this time, because the upper sheet of corrugated cardboard 700 is supported by the clamping plate 200 with which it is in contact, the upper sheet of corrugated cardboard 700 is not curled upward, when the saw blade 300 moves from below upward and the saw teeth 320 approach the lower sheet of another corrugated cardboard 700, the guide 400 drives the saw teeth 320 to the left limit position, the tooth edge of the saw teeth 320 is not located directly below the lower sheet of corrugated cardboard 700, so that the tooth edge of the saw teeth 320 only cuts the corrugated medium sheet located between the two sheets, when the saw teeth 320 are in contact with the lower sheet of corrugated cardboard 700, the lower sheet of corrugated cardboard 700 is subjected to a relatively small upward force from the saw teeth 320, so that the lower sheet of corrugated cardboard 700 is not cut by the tooth edge of the saw teeth 320, the lower sheet of corrugated cardboard 700 will not curl, and similarly, when the saw blade 300 moves downward from above and the saw teeth 320 approach the lower sheet of corrugated cardboard 700, the guide 400 drives the saw teeth 320 to move to the right limit position, with the tooth edges of the saw teeth 320 located directly above the lower sheet of corrugated cardboard 700, and as the saw blade 300 continues to move downward vertically, the tooth edges of the saw teeth 320 contact the lower sheet of corrugated cardboard 700 and cut the lower sheet of corrugated cardboard 700, it will be appreciated that, although the lower sheet of corrugated cardboard 700 is now subjected to a greater downward force from the saw teeth 320, because the lower sheet of corrugated cardboard 700 is also supported by the splint 200 in contact therewith, the lower sheet of corrugated cardboard 700 will not curl downward, when the saw blade 300 moves downward from above and the saw teeth 320 approach the upper sheet of another corrugated cardboard 700, at this time, the guide 400 drives the saw teeth 320 to move to the left limit position, and at this time, the tooth edges of the saw teeth 320 are not located right above the upper surface paper of the corrugated cardboard 700, so that the saw teeth 320 only cut the corrugated medium paper located between the two surface papers, when the tooth edges of the saw teeth 320 are in contact with the upper surface paper of the corrugated cardboard 700, the upper surface paper of the corrugated cardboard 700 is very little acted by the upward force from the saw teeth 320, so that the upper surface paper of the corrugated cardboard 700 is not cut, the upper surface paper of the corrugated cardboard 700 is not curled, in sum, as the saw blade 300 reciprocates in the vertical direction in the feed slot 210 and the corrugated cardboard 700 moves horizontally to the left, the corrugated cardboard 700 is gradually cut by the saw blade 300, the surface paper at the cut position is entirely flat, the phenomenon of collapse or rolling is not easy to occur, so that the overall pressure resistance of the corrugated cardboard is not lowered, the corrugated cardboard 700 is unevenly stressed throughout the stacking and transporting process, thereby reducing the risk of damage to the articles within the corrugated cardboard.
It will be appreciated that when the saw tooth 320 is in the left limit position, the saw tooth 320 is in contact with only the cut side of the corrugated cardboard 700, so that the face paper of the corrugated cardboard 700 is subjected to very little force from the saw tooth 320, and when the saw tooth 320 is in the right limit position, the saw tooth 320 is in contact with the non-cut position of the face paper of the corrugated cardboard 700, so that the face paper of the corrugated cardboard 700 is subjected to very much force from the saw tooth 320, so that the face paper of the corrugated cardboard 700 is cut.

As the saw blade 300 continues to move from bottom to top, the saw teeth 320 approach the upper sheet of corrugated cardboard 700, at which time the guide block 430 pushes the first guide roller 410 to continue to move upwards along the straight groove section 442, but the first guide roller 410 has already been in abutment with the upper groove bottom of the straight groove section 442, so the first guide roller 410 in turn pushes the guide block 430 and the saw teeth 320 to move to the right, at which time the tooth edges of the saw teeth 320 are located directly under the lower sheet of corrugated cardboard 700, and as the saw blade 300 continues to move from bottom to top, the upper sheet of corrugated cardboard 700 is cut.

As the saw blade 300 continues to move from top to bottom, the saw teeth 320 approach the lower sheet of corrugated cardboard 700, at which time the guide block 430 pushes the second guide roller 420 to continue to move upwards along the straight groove section 442, but the second guide roller 420 has already been in abutment with the upper groove bottom of the straight groove section 442, so that the second guide roller 420 in turn pushes the guide block 430 and the saw teeth 320 to move to the right, at which time the tooth edges of the saw teeth 320 are located directly above the lower sheet of corrugated cardboard 700, and as the saw blade 300 continues to move from top to bottom, the lower sheet of corrugated cardboard 700 is cut.
The magnets and the metal bodies are provided so that the positions of the first guide roller 410 and the second guide roller 420 that are in contact with the straight groove end groove bottoms of the corresponding first guide groove 440 or second guide groove 450 can be automatically reset when the first guide roller and the second guide roller are not in contact with the saw teeth 320.
