[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This fume treatment type laser cutting machine draws gas in through a conveying pipe at the fan input end.

The suction hood adsorbs the fume around the cutting workpiece, and the suction hood moves synchronously with the cutting workpiece, which greatly improves the overall fume treatment effect and reduces the space occupation and reduced treatment effect caused by placing the fume treatment structure on the side of the machine box. The specific details are as follows:

[0016] The suction hood adsorbs the fumes around the cutting parts, reducing the space occupation and reduced treatment efficiency caused by placing the fume treatment structure on the side of the chassis.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: In this example, the suction hood 9 moves synchronously with the cutting component 4, greatly improving the overall flue gas treatment effect and reducing the space occupation and reduced treatment effect caused by placing the flue gas treatment structure on the side of the chassis 1. Figures 1-6The technical solution shown includes a housing 1, a support base 3 connected to the housing 1 via a movable base 2, a cutting component 4 mounted on the support base 3, a receiving hopper 5 on the housing 1, a fan 6 inside the housing 1, a conveying pipe 7 connected to the output end of the fan 6, an air suction hood 9 mounted on the support base 3, the conveying pipe 7 connecting the bottom of the receiving hopper 5 to the air suction hood 9, a filter assembly on the conveying pipe 7, the filter assembly including a filter box 8 mounted on the conveying pipe 7, the filter box 8 installed inside the housing 1, a filter plate 10 connected inside the filter box 8 via a spring 11, and a motor 12 inside the housing 1. The output end of the filter box 8 is connected to a rotating shaft 13, which runs through the filter box 8. An eccentric wheel 14 is installed on the outside of the rotating shaft 13. After the eccentric wheel 14 rotates, it contacts the filter plate 10. The cutting part 4 cuts the workpiece on the upper surface of the machine box 1. The receiving hopper 5 on the machine box 1 receives the waste generated during laser cutting. The fan 6 is turned on, and the input end of the fan 6 draws in gas through the conveying pipe 7. The conveying pipe 7 not only adsorbs the waste inside the receiving hopper 5, but also facilitates the adsorption of the smoke around the cutting part 4 by the suction hood 9 through the cooperation of the receiving hopper 5 and the suction hood 9. The whole process can be completed quickly. The system simultaneously collects waste and fumes, preventing waste from scattering and polluting the working environment. It also effectively adsorbs harmful fumes generated during cutting, preventing operators from inhaling harmful gases and ensuring a clean working environment and operator health. The suction hood 9 moves synchronously with the cutting part 4, greatly improving the overall fume treatment effect and reducing the space occupation and reduced treatment efficiency caused by placing the fume treatment structure on the side of the machine casing 1. Because a filter box 8 is installed on the conveying pipe 7, the gas conveyed by the conveying pipe 7 is filtered through the filter plate 10 inside the filter box 8. The filter plate 10 is connected to the inside of the filter box 8 by a spring 11. Therefore, when the motor 12 is turned on, the output end of the motor 12 drives the rotating shaft 13 to rotate, which in turn drives the eccentric wheel 14 to rotate. When the eccentric wheel 14 rotates, it contacts the filter plate 10, causing the filter plate 10 to vibrate through the spring 11. The vibration of the filter plate 10 shakes off the particles in the flue gas, reducing the problem of impurities clogging the filter holes of the filter plate 10 and reducing the filtration efficiency. This extends the service life of the filter plate 10, reduces equipment maintenance costs, and the overall structure is simple, reducing the problem of increased equipment maintenance difficulty and energy consumption caused by complex structures.

[0032] Example 2: In this example, particles are ejected through the jet holes 17 on the rotating shaft 13, facilitating the cleaning of particles on the filter plate 10 and further improving the cleaning effect of the filter plate 10. Specifically, as follows... Figures 3-6As shown, a sleeve 16 is fitted on the outer side of the rotating shaft 13. A first pipe 15 is connected to the side end of the sleeve 16. The inner cavity of the sleeve 16 is connected to the inner cavity of the rotating shaft 13. An air jet hole 17 is opened on the side end of the rotating shaft 13 near the filter plate 10. The laser cutting machine is designed to facilitate the placement of the workpiece to be cut on the upper surface of the machine housing 1. At this time, the screw is driven to rotate by the drive component, so that the moving seat 2 moves through the cooperation of the screw and the guide rod. Since the moving seat 2 is connected to the support seat 3 through the telescopic cylinder, the cutting part 4 on the support seat 3 can be moved in position, which facilitates the cutting part 4 to cut the workpiece on the upper surface of the machine housing 1. The screw and guide rod structure makes the moving seat 2 move stably. The telescopic cylinder responds quickly, enabling the support seat 3 at the output end of the telescopic cylinder to move rapidly, thereby improving the overall laser cutting efficiency. It enables precise cutting of workpieces of different sizes and shapes, improves the versatility and processing accuracy of the equipment, and meets diverse processing needs. The first pipe 15 is connected to the external gas supply component, allowing the first pipe 15 to deliver gas to the inside of the sleeve 16. The gas is then input into the inner cavity of the rotating shaft 13 through the inner cavity of the sleeve 16 and ejected through the jet hole 17 on the rotating shaft 13. This facilitates the cleaning of particles on the filter plate 10, further improving the cleaning effect of the filter plate 10, ensuring the continuous and efficient operation of the filtration system, reducing manual cleaning workload, and improving the automation level of the equipment.

[0033] Example 3: In this example, the heat sink 21 inside the heat sink 19 is used for heat dissipation, reducing the problem of the cutting part 4 being affected by overheating and its cutting accuracy and service life. Specifically, as follows... Figures 1-3 , Figure 7 and Figure 8As shown, a heat dissipation assembly is provided on the outside of the cutting component 4. The heat dissipation assembly includes a heat dissipation cylinder 19 installed on the outside of the cutting component 4. A second pipe 18 is connected to the side end of the heat dissipation cylinder 19. Heat dissipation holes 20 are opened on the outside of the heat dissipation cylinder 19. A heat dissipation component 21 is provided inside the heat dissipation cylinder 19. A shape memory metal sheet 22 is connected to the heat dissipation component 21. The shape memory metal sheet 22 is located on the side end of part of the heat dissipation holes 20. Since the cutting component 4 generates heat during use, the heat dissipation component 21 inside the heat dissipation cylinder 19 absorbs the heat on the cutting component 4. The second pipe 18 is connected to an external gas supply component, so that the second pipe 18 delivers gas into the heat dissipation cylinder 19, facilitating the gas transportation through the heat dissipation cylinder 19 and facilitating the heat dissipation component inside the heat dissipation cylinder 19. The heat dissipation operation 21 not only reduces the problem of the cutting part 4 being affected by overheating in terms of cutting accuracy and service life, but also allows gas to be transported outward through the heat dissipation holes 20 on the outside of the heat dissipation cylinder 19, so that the gas at the cutting position can be effectively circulated. When the temperature of the heat dissipation cylinder 19 continues to rise, the shape memory metal sheet 22 on the heat dissipation part 21 deforms due to heat. At this time, the shape memory metal sheet 22 bends into the heat dissipation cylinder 19, so that some of the heat dissipation holes 20 on the outside of the heat dissipation cylinder 19 are not blocked by the shape memory metal sheet 22, thereby improving the overall heat dissipation efficiency. The whole can automatically adjust according to the temperature, which greatly reduces the overall energy consumption. The contents not described in detail in this specification are the prior art known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
