Description

Technical Field

[0001] This utility model belongs to the field of fiber laser cutting technology, and in particular relates to a fume treatment device for fiber laser cutting machines. Background Technology

[0002] Fiber laser cutting machines process materials using high-energy-density laser beams. The core principle involves using a fiber laser to output a 1.064-micron wavelength laser beam, which is focused to form an ultra-fine focal spot (minimum diameter less than 0.1mm). This instantly generates high temperatures on the workpiece surface (melting or vaporizing the material), and the CNC system controls the movement of the laser spot to complete the cutting. Compared to traditional laser technology, it boasts higher beam quality and power density. Furthermore, fiber transmission eliminates the need for complex optical path adjustments, resulting in a compact structure and strong stability. Fiber laser cutting machines are equipped with a fume extraction device to treat the fumes generated during the cutting process, preventing any impact on the air quality at the work site. This fume extraction device includes a cartridge filter and a fan. The fan generates negative pressure, forcibly drawing the fumes from the cutting area into the cartridge filter.

[0003] Since cartridge filters are consumables and relatively expensive, most dust treatment devices directly filter the dust generated during fiber laser cutting using cartridge filters, requiring frequent replacement of the cartridge filters. Therefore, a dust treatment device for fiber laser cutting machines is needed that can pre-treat and collect large-diameter particles in the dust, thereby improving the cleanliness of the dust before it passes through the cartridge filter and extending the service life of the cartridge filter. Utility Model Content

A washer 11 is fitted on the surface of the bolt rod 10. The washer 11 is an elastic washer. The washer 11 increases the friction between the washer 11 and the lugs 9, preventing the bolt rod 10 from vibrating due to external forces. In the event of a loosening and detachment from the rectangular box 2, a frame 12 is fixedly connected to the bottom of the rectangular box 2. A cylinder 13 is fixedly connected to the surface of the frame 12 by bolts. A rectangular block 14 is fixedly connected to the output end of the cylinder 13.

A connecting rod 17 is rotatably connected between the strip 16 and the rectangular block 14. A slide rail 18 is fixedly connected to the surface of the frame 12 by bolts. A slider 19 is slidably connected to the surface of the slide rail 18. The slider 19 is fixedly connected to the rectangular block 14. Through the cooperation of the slide rail 18 and the slider 19, the movement of the rectangular block 14 is limited, preventing the rectangular block 14 from shaking during movement, thereby improving the stability of the rectangular block 14 during movement. A horizontal plate 20 is welded to the top of the strip 16. A closed cover plate 21 is fixedly connected to the top of the horizontal plate 20.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a dust treatment device for a fiber laser cutting machine according to an embodiment of the present invention. The device includes a fiber laser cutting machine housing 1. A rectangular box 2 is fixedly installed on the top of the housing 1. A fan 3 is fixedly connected to the left side of the rectangular box 2. A filter cartridge 4 is fixedly installed between the fan 3 and the rectangular box 2. A connecting pipe 5 connects the baffles 7 to the housing 1. An exhaust pipe 6 connects to the outlet of the fan 3. Several baffles 7 are staggered and fixedly connected to the inner wall of the rectangular box 2. A collecting base plate 8 is provided at the bottom of the baffles 7. Two symmetrically arranged lugs 9 are welded to the surface of the collecting base plate 8. Bolt rods 10 are installed between the lugs 9 and the rectangular box 2. A frame 12 is fixedly connected to the bottom of the rectangular box 2. A cylinder 13 is bolted to the surface of the frame 12. A rectangular block 14 is fixedly connected to the output end of the cylinder 13. A turntable 15 is rotatably connected to the surface of the frame 12. A strip 16 is fixedly connected to the top of the turntable 15. A connecting rod 17 is rotatably connected between the strip 16 and the rectangular block 14. A horizontal plate 20 is welded to the top of the strip 16. A closed cover plate 21 is fixedly connected to the top of the horizontal plate 20. A sealing ring 22 is pasted on the top of the closed cover plate 21. The sealing ring 22 is a rubber ring. The filter cartridge 4 is a polytetrafluoroethylene membrane polyester filter cartridge. By setting the sealing ring 22, the top of the closed cover plate 21 and the rectangular box 2 are sealed, avoiding the occurrence of gaps between the two, thereby improving the sealing performance of the rectangular box 2.

[0028] Working Principle: When using this invention, the user turns on the fan 3, allowing the welding fume gas appearing in the fiber laser cutting machine housing 1 to enter the rectangular box 2 through the connecting pipe 5. At this time, the baffle 7 turbulently processes the welding fume gas flowing through the rectangular box 2. Through the impact and deflection of the airflow against the baffle, large-diameter dust particles in the airflow are separated by inertial force. Subsequently, the dust particles fall into the collection base plate 8 under the action of gravity and are collected. Then, the airflow is finely filtered through the filter cartridge 4 and discharged through the exhaust pipe 6. The collection base plate 8 and the lug 9 can be detached from the bottom of the rectangular box 2 by the threaded connection of the bolt rod 10, making it easy to remove the collection base plate 8 and the lug 9. The dust particles collected in the bottom plate 8 are discharged and treated externally. The rectangular block 14 is moved by the cylinder 13. At this time, under the limiting action of the turntable 15 and the strip plate 16, the rectangular block 14 drives the strip plate 16 to flip through the connecting rod 17. Then, the strip plate 16 drives the sealing cover plate 21 through the horizontal plate 20 to seal the bottom of the rectangular box 2, thereby ensuring the airtightness of the inner cavity of the rectangular box 2 and preventing the gas in the rectangular box 2 from overflowing from the bottom. This achieves the goal of collecting and pre-treating large-diameter particles in the dust, thereby improving the cleanliness of the dust before it is processed by the cartridge filter, and thus extending the service life of the cartridge filter.

[0029] In summary, this fume treatment device for fiber laser cutting machines uses a baffle plate 7 to turbulent the welding fume gas flowing through the rectangular box 2. By impacting the baffle and turning the airflow, large-diameter fume particles in the airflow are separated by inertial force. Subsequently, the fume particles fall into the collection base plate 8 under the action of gravity and are collected. This achieves the purpose of pre-treating and collecting large-diameter particles in the fume, thereby improving the cleanliness of the fume before it is processed by the cartridge filter, and thus extending the service life of the cartridge filter.
