[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. During the cutting process of metal components, a large amount of metal dust will be generated, so a dust collector is needed to filter out the smoke generated during the laser cutting process.

[0003] The Chinese patent document with application number 2020203014562 discloses an integrated high-efficiency and energy-saving dust collector for a laser cutting machine, comprising a dust collector box and a perforated plate arranged in the dust collector box, the perforated plate divides the dust collector box into an upper box and a lower box, and a high-pressure atomizing nozzle facing the lower box space is also provided on the side wall of the lower box, the high-pressure atomizing nozzle is connected to a water supply device arranged outside the lower box, an exhaust port is provided on the bottom wall of the lower box, an exhaust pipe is provided at the exhaust port, and an exhaust fan with an exhaust direction facing the outside of the lower box is provided on the exhaust pipe.

[0004] The above scheme uses a high-pressure atomizing nozzle to spray humidification and weight increase on the dust, and uses an exhaust fan to quickly extract the weight increase on the dust, which can quickly and thoroughly clean the dust on the outer surface of the bag. However, due to the large number of types of laser cutting dust collectors in the prior art, each laser cutting dust collector has a different box volume, and has different requirements for the spray volume of the atomizing nozzle. However, due to cost considerations, enterprises generally do not purchase atomizing nozzles of various specifications, resulting in a single specification of the atomizing nozzle, which cannot meet the requirements of different spray volumes. Utility Model Content

[0023] like Figure 1-2 As shown, a laser cutting dust collector atomizing nozzle includes an outer shell 1, a stopper 2 and a nozzle 3. The outer side of the outer shell is composed of a rotating part 11, an intermediate part 12 and a connecting part 13. The diameters of the rotating part 11, the intermediate part 12 and the connecting part 13 decrease in sequence. The middle of the outer shell 1 is provided with a first circulation channel 4, a second circulation channel 5 and a slot part 6 from bottom to top in sequence. The connecting part 13 of the outer shell is used to connect with the inside of the laser cutting dust collector case. The laser cutting dust collector case is provided with a corresponding water supply pipe structure. The outer shell is connected to the water supply pipe structure in the laser cutting dust collector case through a threaded structure 16 on the connecting part 13. The water supply pipe passes water through the first circulation channel 4 and the second circulation channel 5 in the outer shell.

[0024] Combination Figure 3A sealing rubber ring 15 is provided on one side of the middle part 12 near the connection part 13. The diameter of the middle part 12 is larger than that of the connection part 13. When the outer shell is rotated, the outer shell continuously moves toward the water supply pipe structure under the action of the threaded structure 16 of the connection part 13 until the middle part 12 abuts against the water supply pipe structure. When the middle part 12 abuts against the water supply pipe structure, the sealing rubber ring 15 is also squeezed between the two to play a corresponding sealing role. When rotating, the rotating part 11 is grasped for rotation. The outer side of the rotating part 11 is provided with a texture structure 14. The texture structure 14 can increase friction and facilitate holding for rotation.

[0025] Combination Figure 2 The stopper 2 is a spherical structure and is located in the second circulation channel 5. The stopper 2 is made of polyvinyl chloride, which is a lightweight plastic with light weight and water corrosion resistance. When the water in the water supply pipe structure flows through the first circulation channel 4 into the second circulation channel 5, it will first impact the stopper 2. A slot 6 is provided at the top of the second circulation channel 5. The slot 6 is bolted to the nozzle 3. The outer diameter of the nozzle 3 matches the slot 6. A conical cavity 7 is provided in the middle below the nozzle 3. A fine hole 8 is provided at the top of the conical cavity 7 to penetrate the nozzle 3. Figure 4-5 A ring 9 is also provided below the nozzle portion 3. The outer diameter of the ring 9 matches the diameter of the second circulation channel 5. The ring 9 is embedded in the second circulation channel 5. A flow groove 10 is provided at the bottom of the ring 9. The flow groove 10 is used to connect the second circulation channel 5 and the inner space of the ring 9. The diameter of the stopper portion 2 is larger than the inner diameter of the ring 9, and the diameter of the stopper portion 2 is smaller than the outer diameter of the ring 9.

[0026] The spherical stopper 2 is impacted to the insert ring 9 below the nozzle part 3 by the water flow, and the spherical stopper 2 will be against the insert ring 9. Since the diameter of the stopper 2 is larger than the inner diameter of the insert ring 9 and smaller than the outer diameter of the insert ring 9, the water will flow into the conical cavity 7 from the side of the stopper 2. However, if the water wants to flow into the conical cavity 7 in the middle below the nozzle part 3 and spray out from the fine hole 8 at the top of the conical cavity 7, it must pass through the flow groove 10 at the bottom of the insert ring 9. Therefore, the number of flow grooves 10 on each insert ring 9 can determine the amount of spraying of each nozzle. When the water flows through the conical cavity 7 and sprays out from the fine hole 8, it is affected by the rapid flow of the surrounding gas to form a high-speed liquid flow. This liquid flow is sheared by the gas, causing the liquid to split into small particles, forming an atomization effect.

[0027] By replacing the nozzle part 3 with different numbers of flow slots 10, the water spraying amount can be conveniently adjusted. When the volume of the laser cutting dust collector box is large, the nozzle part 3 with more flow slots 10 can be switched to increase the spraying amount. When the volume of the laser cutting dust collector box is small, the nozzle part 3 with fewer flow slots 10 can be switched to reduce the spraying amount. The difference in the number of flow slots 10 on the part provides flexibility, and the appropriate water spraying intensity can be selected as needed.

[0028] Combination Figure 5 The cross section of the flow groove 10 in this embodiment is a triangular structure. The triangular groove has relatively small resistance, which helps to reduce the energy loss of water flow and is suitable for the higher flow rate requirements in the atomizing nozzle.

[0029] When the laser cutting dust collector housing is installed, the present embodiment can be installed with the optical cutting dust collector housing by rotating the rotating part 11 and the connecting part 13. When the water flow size needs to be switched, only the nozzle part 3 on the outer shell needs to be replaced, thereby reducing the cost of the enterprise and having the advantages of easy installation and good reliability.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
