The two terms "circumference" and "circumferential surface" are used interchangeably in this document. A plurality of air passages 30 are provided on one end 22 of the round knife mold 10 in the axial direction. The air passages 30 are connected with the corresponding air blowing holes 42. One end 24 of the round knife mold 10 is rotatably provided with an air inlet sleeve 26. The air inlet sleeve can also be referred to as an air inlet sleeve. An air inlet nozzle 50 is rotatably connected with the air passage 30 and is provided in the air inlet sleeve 26.

The profiled top block 40 only contacts the waste material to avoid damaging the product. Therefore, there is a height difference between the profiled top block 40 and the circumferential surface 12 of the circular cutter die 10. When the laser cutting sheet passes through the circular cutter die 10, the profiled top block 40 pushes the waste material out. At least one profiled top block 40 is arranged in the circumferential direction of the circumferential surface 12 of the circular cutter die 10, which is used to discharge the waste material in the row and diameter directions of the plate.

[0024] Referring to Figure 2 , a plurality of blind holes 11A are formed in one end 11 of the circular cutter die 10 in the axial direction thereof, and the blind holes 11A are in communication with the air passages 30. In an embodiment, the air inlet sleeve 26 does not rotate during the rotation of the circular cutter die, which keeps the air passages 30 in communication with the air inlet sleeve 26 of the air inlet nozzle 50, and the air inlet nozzle 50 is in communication with external compressed air and other pressure media through a conventional air pipe. Therefore, the air source is connected to the corresponding air passages 30 of the air blowing holes 42 for providing air flow to blow the waste material out again, ensuring that the waste material is completely removed.

[0025] The laser cutting circular cutter waste discharge die 5 has a simple structure, and a plurality of profiled top blocks 40 with a size similar to that of the product waste are arranged on the circumferential surface 12 of the circular cutter die 10 to push the waste material out of the material belt.

Different profiling top blocks 40 are connected to the same air nozzle through the same air inlet or different compressed air, and the air channels 30 can be arranged in multiple layers from the outside to the inside to avoid conflicts between different air inlets. The multiple layers of air channels 30 connected with each other use the same air inlet or are respectively provided with corresponding air inlets, and each layer of air inlet reaches the circular cutter die 10.

[0030] In one embodiment, the centers of gravity are at the same distance, and a plurality of air channels are arranged in the same layer of the die 10. The spacing between adjacent air channels 30 in the same layer can be the same or different.

The profiled top block 40 is spaced apart from the bottom of the corresponding installation groove 14, and each installation groove 14 is in communication with all the air blowing holes 42 in the corresponding profiled top block 40. The bottom of the profiled top block 40 is provided with an air blowing hole 42, and the air blowing hole 42 is connected with the corresponding air channel 30. The corresponding avoiding groove in the air channel can avoid the flow of compressed air in the air channel being blocked / interfered.
