Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a dust extraction device for a laser cutting machine, including: laser cutting machine body 1, chip removal channel 2, bracket 3, cutting table 4, dust suction port 5, purification box 6, dust suction drum 7, strong blower 8, activated carbon filter element 9, tooth disc 10, motor 11, installation disc 12, fan blade 13, brush 14, push rod 15 and collection tank 16.

[0024] Laser cutting machine body 1, a chip removal channel 2 is arranged at the top of the laser cutting machine body 1, and a dust suction port 5 is opened above the rear side of the chip removal channel 2. A bracket 3 is connected above the chip removal channel 2, and a cutting table 4 is installed above the bracket 3;

[0025] Purification box 6, the purification box 6 is arranged at the rear side of the laser cutting machine body 1, and a dust suction drum 7 is arranged inside the purification box 6. A strong blower 8 is installed above the rear side of the dust suction drum 7, and an activated carbon filter element 9 is arranged below the strong blower 8. An installation disc 12 is arranged at the top of the dust suction drum 7, and a tooth disc 10 is installed at the top of the installation disc 12. The top end of the tooth disc 10 is connected to a motor 11, and the motor 11 is fixedly connected to the purification box 6. A brush 14 is arranged at the rear side of the dust suction drum 7, and a push rod 15 is connected to the outside of the brush 14. And a collection tank 16 is arranged below the dust suction drum 7.

[0026] Such as Figure 1 , Figure 2 and Figure 4The middle chip discharge channel 2 is arranged in an inclined structure, which is convenient for discharging the cutting waste slag. The dust suction drums 7 are symmetrically arranged on the left and right inside the purification box 6, and the dust suction drums 7 are threadedly connected to the mounting plate 12, which is convenient for the installation of the dust suction drums 7. The toothed disc 10 is rotatably connected to the purification box 6 through the mounting plate 12, and a fan blade 13 is arranged inside the toothed disc 10, and the fan blade 13 is located inside the mounting plate 12. Moreover, the individual dust suction drums 7 are meshed and connected through the toothed disc 10, which is convenient for generating an air pressure from the inside to the outside in the dust suction drums 7.

[0027] As Figure 3 and Figure 4 The middle push rod 15 is slidably and sealedly connected to the purification box 6, and brushes 14 are correspondingly arranged on the left and right of the push rod 15, and the brushes 14 are movably connected to the dust suction drums 7, which is convenient for improving the sealing performance of the purification box 6. The collection tank 16 is detachably connected to the purification box 6, which is convenient for collecting and cleaning the soot.

[0028] Working principle: When using the dust extraction device for the laser cutting machine, as Figure 4 shown, by starting the powerful blower 8, the powerful blower 8 sucks the soot into the purification box 6 through the dust suction port 5, and filters and purifies it through the dust suction drums 7. The purified gas is further purified by the activated carbon filter element 9 to remove the peculiar smell. At the same time, the inclined structure of the chip discharge channel 2 facilitates the cutting waste slag to flow into the purification box 6 under the action of gravity and negative pressure;

[0029] When it is necessary to clean the purification box 6, as Figure 3 shown, by pushing the push rod 15, the push rod 15 drives the brush 14 to contact the dust suction drum 7. At the same time, the motor 11 is started, so that the motor 11 drives the toothed disc 10 to rotate. The individual dust suction drums 7 are meshed through the toothed disc 10, so that the individual dust suction drums 7 rotate synchronously. When the toothed disc 10 rotates, an air flow from the inside to the outside is generated through the fan blade 13, which is convenient for blowing off the soot adsorbed on the dust suction drums 7. At the same time, through the contact between the dust suction drums 7 and the brushes 14, the cleaning efficiency is improved. The cleaned soot particles fall into the collection tank 16 for collection and treatment. This is the entire working process of the dust extraction device for the laser cutting machine.
