The rotating connecting gear 4010 drives another rotating shaft 408 to rotate. Then, the two rotating shafts 408 rotate synchronously.

[0035] Please refer specifically to Figure 2 , the rotating plate 401 is fixedly installed on the outer wall of the rotating shaft 408, and a plurality of through holes 402 are formed on the surface of the rotating plate 401.

The debris generated during the cutting process will fall into the collection hopper 406 through the plurality of through holes 402 formed on the surfaces of the two rotating plates 401.

[0037] Please refer specifically to Figure 5 , the conveying assembly includes a through groove 403, a discharge rack 404, a collection hopper 406, a servo motor 407 and a spiral auger 4012;

[0038] The collection hopper 406 is fixedly installed inside the cutting table 2, the servo motor 407 is fixedly installed outside the cutting table 2, the through groove 403 is formed on the inner wall of the collection hopper 406 and penetrates to the outside of the cutting table 2, the discharge rack 404 is fixedly connected inside the through groove 403, and the spiral auger 4012 is rotatably installed inside the collection hopper 406.

[0039] In this embodiment: The servo motor 407 is powered on and operated, and the output shaft of the servo motor 407 in the operating state drives the spiral auger 4012 to rotate. The rotating spiral auger 4012 conveys the debris collected inside the collection hopper 406 towards the direction of the through slot 403, and then the debris is discharged outside the collection hopper 406 and the cutting table 2 through the through slot 403 and the discharge rack 404.

[0040] Please refer specifically to Figure 5 , the spiral auger 4012 is fixedly connected to the end of the output shaft of the servo motor 407, and the output shaft of the servo motor 407 in the operating state is used to drive the spiral auger 4012 to rotate.

[0041] In this embodiment: The output shaft of the servo motor 407 in the operating state drives the spiral auger 4012 to rotate, and the rotating spiral auger 4012 conveys the debris collected inside the collection hopper 406 towards the direction of the through slot 403.

[0042] Please refer specifically to Figure 3 , the two rotating plates 401 rotated to the inclined state are used to open the opening of the cutting table 2, and the two rotating plates 401 rotated to the horizontal state are used to close the opening of the cutting table 2.

[0043] In this embodiment: The two rotating plates 401 are respectively driven by the two rotating shafts 408 in the rotating state to rotate to the inclined state. The two rotating plates 401 rotated to the inclined state open the opening of the cutting table 2, and a little debris remaining on the two rotating plates 401 naturally slides down along their inclined surfaces into the collection hopper 406.

[0044] Please refer specifically to Figure 5 , the collection hopper 406 is used to uniformly receive the debris, and the discharge rack 404 is inclined.

[0045] In this embodiment: The debris generated during the cutting process will fall into the collection hopper 406 through a number of through holes 402 opened on the surfaces of the two rotating plates 401, and a little debris remaining on the two rotating plates 401 naturally slides down along their inclined surfaces into the collection hopper 406. Then, the collection hopper 406 uniformly collects the debris generated during the sheet metal cutting.

[0046] Working principle: First, place the sheet metal to be cut on the two rotating plates 401 in the horizontal state of the cutting table 2, and use the laser cutting mechanism 3 in the electrified state to cut the sheet metal. The debris generated during the cutting process will fall into the collection hopper 406 through several through holes 402 opened on the surfaces of the two rotating plates 401. After the sheet metal is completely cut, remove the cut sheet metal from the two rotating plates 401 in the horizontal state of the cutting table 2. At this time, there is still some debris remaining on the two rotating plates 401. Then, energize and operate the shaft-holding motor 4011, so that the output shaft of the operating shaft-holding motor 4011 drives a rotating shaft 408 and a transmission gear 409 to rotate. Since the transmission gear 409 meshes with the connecting gear 4010, the rotating transmission gear 409 drives the connecting gear 4010 to rotate. The rotating connecting gear 4010 drives the other rotating shaft 408 to rotate. Then, the two rotating shafts 408 in the rotating state drive the two rotating plates 401 to rotate to the inclined state. The two rotating plates 401 in the inclined state open the opening of the cutting table 2, and the some debris remaining on the two rotating plates 401 naturally slides down along their inclined surfaces into the collection hopper 406. Furthermore, the collection hopper 406 uniformly collects the debris generated during the sheet metal cutting;

[0047] At this time, energize and operate the servo motor 407, so that the output shaft of the operating servo motor 407 drives the spiral auger 4012 to rotate. The rotating spiral auger 4012 conveys the debris collected inside the collection hopper 406 towards the direction of the through slot 403. Furthermore, the debris is discharged out of the collection hopper 406 and the cutting table 2 through the through slot 403 and the discharge rack 404. Thus, the above structure facilitates the removal of the debris generated during the sheet metal cutting.
