[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, in the present invention, the blowing pipe 2 and the supplementary side blowing pipe 7 are arranged in an L shape, and the bottom of the blowing pipe 2 and the supplementary side blowing pipe 7 are arranged vertically, and the air supply box 1 and the blowing pipe 2 connected with the air supply box 1 are supplied with air by an external fan, and the air supply box 1 is fixed on one side of the cutting position of the laser cutting machine, and the air flow blown out by the blowing pipe 2 is used to side-blow the slag generated at the cutting position, and the bottom end of the blowing pipe 2 can be rotated on the top of the air supply box 1 to start the driving motor 6, and the driving motor 6 can drive the driving gear 5 to rotate, and the driving gear 5 drives the external gear 4 on the blowing pipe 2 matched therewith to rotate, and the blowing pipe 2 rotates with the driving gear 5 to adjust the direction of the blown air flow, thereby expanding the blowing angle and range of the blowing pipe 2.

[0019] The utility model is provided with a supplementary side blow pipe 7, and an external gear 4 is also provided on the supplementary side blow pipe 7. The bottom of the supplementary side blow pipe 7 is rotatably mounted with a mounting plate 8. The mounting plate 8 and the supplementary side blow pipe 7 can be driven to move up and down by the extension and contraction of the hydraulic telescopic shaft 9. With the movement of the supplementary side blow plate, the external gear 4 on the supplementary side blow pipe 7 can be driven to rise or fall. Figure 3 When the external gear 4 on the supplementary side gear falls to the upper surface of the air supply box 1, the two sets of external gears 4 cooperate with each other, and the blowing pipe 2 and the supplementary side blowing pipe 7 are linked. The control valve 10 on the supplementary side blowing pipe 7 can control the opening and closing of the supplementary side blowing pipe 7. When the blowing pipe 2 and the supplementary side blowing pipe 7 are linked, the control valve 10 will be started to open the supplementary side blowing pipe 7. The blowing pipe 2 and the supplementary side blowing pipe 7 can supply air to the cutting position at the same time, and the blowing angles of the blowing pipe 2 and the supplementary side blowing pipe 7 can also be adjusted at the same time. Figure 4 When the external gear 4 on the supplementary side gear rises to above the external gear 4 on the blowing pipe 2, the two groups of external gears 4 lose coordination, and the blowing pipe 2 can move independently. The air flow loss is not avoided by starting the control valve 10 to close the supplementary side blowing pipe 7, and the blowing pipe 2 supplies air to the cutting position.

[0020] The utility model can rotate the root of the blowing pipe 2 by matching the driving gear 5 and the external gear 4, so that the direction of the airflow in the blowing pipe 2 and the angle with the cutting position are changed, the applicability is stronger, and the side blowing effect is increased. By setting the supplementary side blowing pipe 7, the blowing pipe 2 and the supplementary side blowing pipe 7 can supply air to the cutting position at the same time, and the matching of the two groups of external gears 4 can also be controlled by the extension and retraction of the hydraulic telescopic shaft 9. It is flexible to choose to use the blowing pipe 2 and the supplementary side blowing pipe 7 at the same time or to use the blowing pipe 2 alone.
