[0035] With reference to Figure 3 , Figure 5 and Figure 6The interior of the cutter 1 is fixedly connected to a workbench 9, and a plurality of sawtooth bars 10 are fixedly connected to the interior of the workbench 9. The workbench 9 is the place where materials are processed, and the sawtooth bars 10 can increase the friction of the materials so that they will not move easily during processing. The top front end of the workbench 9 is fixedly connected to a cylinder 11, and the driving end of the cylinder 11 is fixedly connected to a push block 12. The push block 12 can be pushed to move by the cylinder 11. The bottom of the push block 12 is slidably connected to the top front end of the workbench 9. The left and right ends of the push block 12 are rotatably connected to two connecting rods 13. When the push block 12 moves, The two connecting rods 13 are connected to each other by a connecting rod 14. When the two connecting rods 13 are close to each other, the two connecting rods 14 can be pulled close to each other. The rear sides of the two connecting rods 14 are fixedly connected with clamping blocks 15, so that the clamping blocks 15 can clamp the materials to be cut inward. The front end of the top of the workbench 9 is rotatably connected to a plurality of linkage rods 16. The rear ends of the two linkage rods 16 are rotatably connected to the upper and lower ends of one of the connecting rods 13. The circular movement can be achieved through the linkage rod 16, so as to pull the connecting rod 13.

[0036] The bottom of the pushing block 12 is fixedly connected with a limit assembly for limiting the pushing block 12. The limit assembly includes a limit block 17.

The outside of the motor 20 is fixedly connected to the right end of the cutter 1. The driving end of the motor 20 is fixedly connected to a rotating rod 21. The motor 20 can drive the rotating rod 21 to rotate. The rotating rod 21 is fixedly connected to a displacement rod 22. When the rotating rod 21 rotates, the displacement rod 22 can move forward. The other end of the displacement rod 22 is rotatably connected to a cross bar 23. The rear end of the cross bar 23 rotates It is connected with a push plate 24, and the displacement rod 22 can move the cross bar 23 and push the push plate 24 to move at the same time. The bottom of the push plate 24 contacts the inner bottom end of the cutter 1, and the inner bottom end of the cutter 1 is slidably connected with a debris collection box 25, so that the push plate 24 can push the waste inside the cutter 1 to the inside of the debris collection box 25. When the motor 20 is reversed, the push plate 24 can be moved back. Through the effect of automatic cleaning, the time for manpower cleaning is greatly reduced, and the labor cost of manpower can be reduced.

[0038] Working principle: When it is necessary to clamp the material, the cylinder 11 is first started to pull the pushing block 12 to move. When the pushing block 12 moves, it can drive the connecting rods 13 on both sides to move to one side. When the connecting rod 13 moves, the linkage rod 16 can be offset at an angle. Secondly, the two pairs of connecting rods 13 can be brought close to each other. When the two pairs of connecting rods 13 are close to each other, the two connecting rods 14 can be pulled close to each other, so that the clamping block 15 can clamp the material to be cut inward. When the material is placed on top of multiple sawtooth bars 10, it has been positioned by the two clamping blocks 15, and the triangle at the top of the sawtooth bar 10 can increase the friction between the material and the limit block 17 can slide inside the slide groove 18, so that the pushing block moves along the shape of the slide groove 18, thereby achieving the effect of limiting the moving direction of the pushing block 12.

[0039] At this time, the slider 5 sliding at the bottom of the two slide rails 4 can drive the guide rail 6 to move. After the guide rail 6 determines the position, it is calibrated by the sliding block 7 at the bottom of the guide rail 6. At this time, the laser cutting head 8 is aligned with the material to be cut and emits a laser to achieve the cutting effect. When the cutting is completed, the cut waste falls to the bottom end of the inner part of the cutter 1.

[0040] When it is necessary to clean the waste material at the bottom of the cutter 1, the motor 20 is first started to drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it can drive the external fixed displacement rod 22 to rotate in a circular rotation. When the displacement rod 22 rotates, it can drive the cross bar 23 to move forward. When the cross bar 23 moves forward, it can drive the push plate 24 to move, so that the push plate 24 can push the waste inside the cutter 1 to the inside of the debris collection box 25. When the motor 20 is reversed, the push plate 24 can be moved back. Through the automatic cleaning effect, the time for manpower cleaning is greatly reduced, and the labor cost can be reduced at the same time.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
