[0028] The support frame 11 is arranged at the top end of the side plate 1, and the cross section of the support frame 11 is in an inverted U shape;

[0029] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when in use, the support frame 11 can support the limiting roller 1004, so as to facilitate the limiting of the conveyed corrugated cardboard, and avoid the position deviation during the slitting process, which affects the slitting effect;

[0030] A limiting mechanism 10 is disposed inside one side of the support frame 11;

[0031] The limiting mechanism 10 includes an adjusting rod 1001, and the adjusting rod 1001 is arranged inside the supporting frame 11, and an adjusting block 1002 is sleeved on the outer side of the adjusting rod 1001, a movable plate 1003 is installed on one side of the adjusting block 1002, and fixed blocks 1005 are installed on both sides of the bottom end of the movable plate 1003, and sleeve blocks 1006 are installed on the bottom ends of the fixed blocks 1005, and a limiting roller 1004 is installed on one side of the sleeve block 1006;

[0032] The cross section of the limiting roller 1004 is circular, and the material of the limiting roller 1004 is rubber;

[0033] There are two sets of blocks 1006, which are symmetrically distributed, and movable grooves are provided inside the two sets of blocks 1006;

[0034] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, when in use, the adjusting rod 1001 is screwed to drive the adjusting block 1002 to move downward, and the movable plate 1003 and the fixed block 1005 cooperate to drive the limiting roller 1004 to move downward until the limiting roller 1004 and the top of the corrugated paperboard to be cut are in contact with each other.

[0039] Working principle: When the utility model is used, first, by placing the corrugated cardboard on the conveying roller 5, the adjusting motor 8 is started to drive the driving shaft 17 to rotate, and the driving shaft 17 drives the driving gear 18 to rotate synchronously while the driving gear 18 rotates, and the chain 6 drives the auxiliary gears 14 to rotate while the chain 6 rotates, thereby driving the auxiliary shaft 15 and the slitting shaft 16 to rotate respectively, and the slitting shaft 16 drives the slitting knife 4 to rotate while the driven gear 7 drives the driven shaft 9 to rotate. Through the above operation, the conveying roller 5 and the slitting knife 4 can be driven to rotate synchronously, thereby achieving the purpose of automatically cutting the corrugated cardboard;

[0040] Then, by screwing the adjusting rod 1001, the adjusting block 1002 is driven to move downward, and the adjusting block 1002 moves downward while driving the movable plate 1003 to move downward synchronously, and the movable plate 1003 moves downward while driving the guide block 13 to slide on the guide rod 12. The guide block 13 can limit the moving movable plate 1003 on the one hand to avoid positional deviation during the movement, which affects the subsequent limit clamping operation, and can also limit the moving movable plate 1003 on the other hand. The movable plate 1003 is guided in a row, thereby making the movement of the movable plate 1003 more stable. When the movable plate 1003 moves downward, it drives the fixed block 1005 to move downward synchronously, thereby driving the limiting roller 1004 to move downward synchronously, until the bottom end of the limiting roller 1004 fits with the top end of the corrugated cardboard. In addition, by providing the sleeve block 1006, the corrugated cardboard can be limited and clamped without affecting the slitting operation of the corrugated cardboard. The above operation facilitates the limit clamping of corrugated cardboards of different sizes, thereby improving its flexibility.
