Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting machine flue cleaning devices, and particularly to laser cutting machine flue cleaning devices. Background Technology

[0002] Laser cutting machines, as high-precision and high-efficiency processing equipment, work by using a high-energy-density laser beam to irradiate the workpiece, causing it to melt or vaporize instantly, thus achieving the cutting purpose. This process generates a large amount of smoke and debris. If these pollutants are not removed in time, they will not only affect the working environment but also damage the optical system and mechanical components of the laser cutting machine. Therefore, appropriate smoke extraction equipment is often installed on laser cutting machines.

[0003] Existing adsorption flue structures are relatively simple, leading to a gradual accumulation of smoke and dust within the flue. Over time, the thickness of the dust buildup increases, hindering the smooth discharge of flue gas, reducing exhaust efficiency, and corroding the flue walls, thus shortening its lifespan. When cleaning is required, operators often need to spend considerable time and effort, sometimes even requiring specialized tools. This cumbersome cleaning process not only increases costs but also disrupts production schedules due to prolonged downtime. Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a device for cleaning the flue of a laser cutting machine.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A laser cutting machine flue cleaning device includes an adsorption flue, in which a filter screen is installed and fixedly engaged with the adsorption flue. An auxiliary baffle is installed in the filter screen and fixedly connected to the filter screen. A cleaning rotator is installed in the auxiliary baffle and rotatably connected to the auxiliary baffle. An operating handle connected to the cleaning rotator is provided at the center of the lower end face of the auxiliary baffle.

[0007] As a preferred embodiment, the filter screen housing includes an arc-shaped mesh and an inner ring shell, wherein the inner ring shell is installed on the lower end face of the arc-shaped mesh and is fixedly connected to the arc-shaped mesh.

[0008] As a preferred embodiment, the auxiliary baffle includes a chassis and an inner support frame. The chassis is fixedly installed in the inner support frame, and the inner support frame is supported and fixed on the inner side of the inner ring shell. A bushing for the cleaning rotating frame to be rotatably installed is provided at the center of the upper end face of the chassis, and the bushing is fixedly connected to the chassis.

[0009] As a preferred embodiment, the chassis is provided with a ash discharge trough, and an inclined shell is provided directly below the ash discharge trough, the inclined shell being integrally formed with the chassis.

[0010] As a preferred embodiment, the inner support frame includes a disc shell and side support rods, the side support rods being evenly distributed on the outer surface of the disc shell and integrally formed with the disc shell.

[0011] As a preferred embodiment, the cleaning swivel includes a central shaft and an outer frame plate, the central shaft being rotatably mounted in a bushing, and the outer frame plate being fixedly mounted on the outer side of the central shaft.

[0012] As a preferred embodiment, an arc-shaped scraper that matches the inner side of the arc-shaped mesh is fixedly installed on the upper end face of the outer frame plate, and a curved baffle is provided on one side of the outer frame plate, the curved baffle being integrally formed with the outer frame plate.

[0013] Compared with existing technologies, the advantages of this invention are as follows: In real-time use, the cleaning frame can be rotated by turning the operating handle, and the dust on the arc-shaped screen is scraped off by the arc-shaped scraper and discharged through the ash discharge chute and inclined shell. This eliminates the need to disassemble the flue, greatly improving cleaning efficiency and saving cleaning time and labor costs. The arc-shaped mesh of the filter shell effectively filters large particles of impurities in the smoke, reducing dust accumulation in the flue, extending the service life of the flue, ensuring the smoke extraction effect of the laser cutting machine, and thus improving the working stability and cutting quality of the laser cutting machine.

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, the laser cutting machine flue cleaning device includes an adsorption flue 1, a filter screen 2 installed in the adsorption flue 1, the filter screen 2 being engaged and fixed with the adsorption flue 1, an auxiliary baffle 3 installed in the filter screen 2, the auxiliary baffle 3 being fixedly connected with the filter screen 2, and a cleaning rotating frame 4 installed in the auxiliary baffle 3, the cleaning rotating frame 4 being rotatably connected with the auxiliary baffle 3, and an operating handle 5 connected to the cleaning rotating frame 4 being provided at the center of the lower end face of the auxiliary baffle 3. By installing an adsorption flue 1 on the laser cutting machine, the fumes generated during the cutting process can be adsorbed in real time. A filter screen 2 is installed in the adsorption flue 1 to ensure the filtration of dust and other solid particles in the adsorbed fumes. An auxiliary baffle 3 is installed in the filter screen 2 to ensure that the fumes can only enter between the auxiliary baffle 3 and the filter screen 2 during adsorption, achieving the purpose of annular adsorption. A rotatable cleaning frame 4 is installed in the auxiliary baffle 3, allowing for stable rotation during use. The cleaning frame 4 cleans the deposits on the filter screen 2 and also stably removes dust and impurities from the auxiliary baffle 3. An operating handle 5 is located at the center of the lower end face of the auxiliary baffle 3 and connected to the cleaning frame 4. The operator can easily control the rotation of the cleaning frame 4 by rotating the operating handle 5 to perform the cleaning operation of the flue. The operation is simple and convenient, requiring no complicated tools or equipment.

[0028] Reference Figure 2 and Figure 3 As shown, the filter housing 2 includes an arc-shaped mesh 21 and an inner ring shell 22. The inner ring shell 22 is installed on the lower end face of the arc-shaped mesh 21 and is fixedly connected to the arc-shaped mesh 21. The arc-shaped mesh 21 of the filter housing 2 can filter the smoke and dust generated by laser cutting, intercept large particles of impurities, prevent them from accumulating in the flue, and reduce the burden of subsequent cleaning. The fixed connection between the inner ring shell 22 and the arc-shaped mesh 21 not only provides a stable installation position for the auxiliary baffle 3, but also enhances the structural strength of the entire filter housing 2, enabling it to better withstand the airflow impact in the flue.

[0029] Reference Figure 4As shown, the auxiliary baffle 3 includes a chassis 31 and an inner support frame 32. The chassis 31 is fixedly installed in the inner support frame 32, which is supported and fixed on the inner side of the inner ring shell 22. The inner support frame 32 includes a disc shell 321 and side support rods 322. The side support rods 322 are evenly distributed on the outer side of the disc shell 321 and are integrally formed with the disc shell 321. A bushing 311 for rotating the cleaning rack 4 is provided at the center of the upper end face of the chassis 31. The bushing 311 is fixedly connected to the chassis 31. The disc shell 321 and the side support rods 322 of the inner support frame 32 are integrally formed. The evenly distributed side support rods 322 firmly support the chassis 31 on the inner side of the inner ring shell 22, ensuring the stability of the chassis 31. The disc shell 321 is connected to the inner ring shell 22 through the side support rods 322. A smoke extraction gap is maintained between the disc shell 321 and the inner ring shell 22 to facilitate the even entry of flue gas into the filter screen shell 2. The bushing 311 on the chassis 31 provides precise rotational support for the cleaning swivel frame 4, allowing it to rotate smoothly. A dust discharge trough 312 is provided on the chassis 31, and an inclined discharge shell 313 is integrally formed with the chassis 31. The dust discharge trough 312 and the inclined discharge shell 313 ensure that the cleaned dust can be discharged smoothly, preventing accumulation on the chassis 31 and maintaining the cleanliness of the flue.

[0030] Reference Figure 5 and Figure 6 As shown, the cleaning swivel frame 4 includes a central shaft 41 and an outer frame plate 42. The central shaft 41 is rotatably mounted in a bushing 311, and the outer frame plate 42 is fixedly mounted on the outer side of the central shaft 41. An arc-shaped scraper 421 that mates with the inner side of the arc-shaped mesh 21 is fixedly mounted on the upper end face of the outer frame plate 42. A curved baffle 422 is provided on one side of the outer frame plate 42, and the curved baffle 422 is integrally formed with the outer frame plate 42. The central shaft 41 of the cleaning swivel frame 4 is rotatably mounted in the bushing 311, and the outer frame plate 42 is fixed to the outer side of the central shaft 41. By rotating the operating handle 5, the central shaft 41 is rotated, thereby causing the outer frame plate 42 to rotate around the shaft. The arc-shaped scraper 421 on the outer frame plate 42 fits tightly with the inner side of the arc-shaped mesh 21, and can efficiently scrape off the dust adhering to the arc-shaped mesh 21 during rotation. The curved baffle 422 allows the dust to be concentrated and moved towards the dust discharge trough 312, improving the cleaning effect.

[0031] In this embodiment, when the flue needs to be cleaned, the operator only needs to turn the operating handle 5. The operating handle 5 drives the central shaft 41 to rotate, thereby causing the outer frame plate 42 to rotate around the shaft. As the outer frame plate 42 rotates, the arc-shaped scraper 421 on it scrapes away the dust on the inner side of the arc-shaped mesh 21. The scraped-off dust is concentrated and moves towards the ash discharge trough 312 under the action of the curved baffle 422, and then discharged from the flue through the inclined discharge shell 313.

[0032] The above are preferred embodiments of the present utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on the present utility model shall fall within the protection scope of the present utility model.
