[0041] A process for a cutting device of a laser composite cutting machine, the process comprising the following steps:

[0042] S1, adding clean water into the water tank, placing the plate 100 in the groove 21, and fixing the plate 100 by a fixing mechanism;

[0043] like Figure 1-2 As shown, the device can be moved to the working position by the self-locking universal wheel 11, and clean water is added to the water tank, and the clean water should overflow the slag falling pipe 75.

[0044] like Figure 5 As shown, the plate 100 is placed in the groove 21, and the knob on the head of the adjusting shaft 33 can be used to drive it to rotate. Since the front and rear adjustment seats 32 are engaged with the threaded grooves 35 with opposite rotation directions, the two adjustment seats 32 can be driven to approach each other when the adjusting shaft 33 rotates, so that the fixing plates 36 on the front and rear sides clamp and fix the plate 100, and the fixing mechanisms on the left and right sides fix the left and right sides of the plate 100 respectively.

[0045] S2, start the third fan to make the slag cleaning device work;

[0046] like Figure 7-8 As shown, when the third fan is working, it drives the shaft 713 to rotate, and the shaft 713 drives the rotating shaft 711 and the fan blade group 712 to rotate through the bevel gear pair 714. The inclination direction of the fan blade group 712 is set so that when it rotates, the air at the position of the fan blade group 712 flows from top to bottom.

[0047] like Figure 2-4 As shown, the fan blade group 712 inputs air into the wind gathering bin 71 through the conveying pipe 710 and sprays it out from the nozzle 79. The waste slag and smoke generated during cutting are blown by the flowing air and enter the collecting chamber 74 through the slag inlet 77 and enter the clean water through the slag dropping pipe 75.

[0048] S3, controlling the movement of the plate 100 and the laser generator 5 by the first motor 42 and the second motor 62, starting the laser generator 5, and performing laser cutting on the plate 100.

[0049] like Fig. 9 As shown, when the laser generator 5 is working, the laser can be focused by the focus adjustment knob 52 .

[0050] like Figure 1 and Figure 5 As shown, when the first motor 42 is working, it drives the transverse screw 41 on the front side to rotate. Under the action of the transmission wheel 45 and the belt 46, the transverse screw 41 on the rear side rotates synchronously. Since the movable seat 2 is engaged with the transverse screw 41 through the track plate 43, the rotation of the transverse screw 41 can drive the movable seat 2 and the plate 100 to move horizontally.

[0051] like Figure 1 and Fig. 9 As shown, when the second motor 62 is working, it drives the longitudinal screw 61 to rotate, thereby driving the laser generator 5 to move longitudinally.

[0052] The laser generator 5 moves longitudinally and the plate 100 moves transversely, so that the plate 100 can be cut in a two-dimensional plane.
