two semicircle cutters 351 at the middle part move to opposite directions, and two semicircle cutters 351 at the outside move in opposite directions with the semicircle cutters 351 at the middle part, so that the purpose of controlling the length of the left end and the right end of the groove by only one screw 342 is achieved.

The collecting device 4 comprises a collecting frame 41 and a collecting box 42, the collecting frame 41 is fixedly arranged on the lower end face of the workbench 1, and the collecting box 42 is arranged at the lower end of the collecting frame 41 through a buckle; the waste of the cut and grooved corrugated cardboard falls into the collecting box 42 through the storage plate 31 and the belt conveyor 21.

During the specific operation, the corrugated cardboard is moved to the cutting device 2 through the belt conveyor 21, the telescopic frame 22 is adjusted to enable the pressing frame 24 to press the corrugated cardboard, the motor 26 drives the circular knife 281 to cut the corrugated cardboard, the rubber ring 282 on the circular knife 281 trims the cut corrugated cardboard, the small scraper 283 removes burrs at the cut part of the corrugated cardboard, the cut corrugated cardboard enters the slotting device 3, the rotating rod 343 is rotated to drive the screw 342 to rotate, the screw 342 is rotated to drive the semicircular cutter 351 to do linear motion on the screw 342 to adjust the slotting length, the rotating rod 343 is fixed through the fixture block 344 to fix the screw 342, the T-shaped rod 313 is controlled to drive the arc-shaped block 312 to move, the length of the waist-shaped grooves at the left side and the right side of the thick plate 311 is changed to be in accordance with the length of the slotting cutter 35, and then the T-shaped rod 313 is clamped through the W-shaped, when the corrugated cardboard is grooved, the spring 354 receives a pressing force generated by the waste material when the corrugated cardboard is grooved, thereby generating a reverse acting force to press the waste material through the rubber head 355, so that the waste material is finally dropped into the collecting box 42.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
