[0024] Please refer to Figures 1 to 10, the present invention provides the following embodiments: A four-axis CNC laser cutting device, including a chassis 1 and a laser cutting mechanism 2 disposed inside the chassis 1.

A filter element 304 for filtering waste gas is installed on each driving part. Each filter element 304 is annularly arranged around the electric rotating disk 302. One of the filter elements 304 is connected to the through pipe 7. After filtering the waste gas, the electric rotating disk 302 changes the position of the filter element 304 to complete the replacement of the filter element 304. The driving part can change the distance between two opposite filter elements 304 and can drive the filter element 304 to rotate. A cleaning shaft 303 is fixed at the center of the electric rotating disk 302. The driving part makes the rotating filter element 304 contact the cleaning shaft 303 to clean the filter of the filter element 304 by scrubbing. The laser cutting mechanism 2 adopts a four-axis linkage structure. The X / Y axes are responsible for planar movement, the Z axis controls the height of the cutting head, and the R axis realizes the rotary cutting of pipes or special-shaped workpieces. The R axis adopts a laser cutting machine with a cutting head that can rotate 360°. High-precision and non-blind-angle cutting of the processed parts is completed. When cutting metal materials, laser cutting will generate metal dust and acidic gases. The metal dust and acidic gases are sucked through the through pipe 7 into the purification area by the air pump in the mounting box 5. The metal dust is filtered by the filter element 304, and the acidic gas is filtered by the alkaline solution provided in the cleaning liquid storage tank 401.

[0025] In this embodiment, the driving part includes a screw-type electric slide rail 305 and a micro motor 301. A screw sleeve 306 is arranged on the screw of the screw-type electric slide rail 305. One end of the screw sleeve 306 is fixedly installed with a micro motor 301. The output shaft of the micro motor 301 is fixedly connected with a clamping shaft 307. The clamping shaft 307 fixes the filter element 304. A bracket 308 is fixedly installed inside the chassis 1 in the filtering area.

The clamping shaft 307 includes a screw sleeve 3071 and a screw 3072. The screw sleeve 3071 and the screw 3072 are cooperatively fixed. A groove matching the clamping shaft 307 is opened at the center of the filter element 304. When the clamping shaft 307 fixes the filter element 304, the ends of the two are flush. Support plates 14 are arranged on both sides of the purification mechanism 3. Three mutually isolated small chambers are formed between the partition plate 6, the two support plates 14 and the inner wall of the chassis 1. The purification mechanism 3 is located in the middle small chamber. The other two small chambers are respectively installed with a cleaning mechanism 4 and an installation box body 5. The filter element 304 docked with the through pipe 7 can be rotated and replaced in position through the electric rotating disc 302, so as to complete the replacement of the filter element 304. A plurality of filter elements 304 are provided and automatically replaced, so that the equipment does not need to manually replace the filter element during long-term operation, improving the processing efficiency and ensuring the workshop environment. The cleaning mechanism 4 includes a cleaning liquid storage tank 401 and a box body 402. The cleaning liquid storage tank 401 stores liquid. The cleaning liquid storage tank 401 is communicated with the box body 402. A water inlet pipe 405 is also communicated at the bottom of the box body 402.

[0026] In this embodiment, the purification mechanism 3 further includes a motor 404. The motor 404 is fixed on the inner wall of the chassis 1. The output shaft of the motor 404 rotates through the bottom of the box body 402. One end of the output shaft of the motor 404 located inside the box body 402 is fixedly connected with a stirring shaft 406. A spray head 403 is arranged outside the box body 402. The spray port of the spray head 403 is aligned with the cleaning shaft 303. Pipe openings 16 are arranged at both the upper and lower ends on one side of the storage tank 13. The pipe opening 16 located above is connected with an exhaust pipe, and the other pipe opening 16 is connected with a drain pipe. A gas detector 15 is also installed inside the storage tank 13. When the waste gas is discharged into the storage tank 13 and neutralized with the waste liquid to the set index, it is discharged to the outside through the pipe opening 16. The subsequent flushing alkaline solution is stored inside the storage tank 13 through the drain trough 12, and the filtered high-temperature gas is discharged into the alkaline solution through the third pipe 502. After the high-temperature acidic gas and the alkaline solution undergo a chemical reaction and neutralize, the gas detector 15 can detect the acidic content in the waste gas, and after reaching the emission standard, it is discharged through the pipe opening 16 arranged at the upper part.

[0027] In this embodiment, a drain trough 12 is provided in the filtering area. A first pipe 11 is connected to the drain trough 12 and is internally connected to the storage tank 13. The upper and lower ends of the installation box body 5 are respectively connected to a second pipe 501 and a third pipe 503. The end of the second pipe 501 is arranged inside the middle small chamber, and the end of the third pipe 502 is arranged at the bottom of the storage tank 13. On the opposite sides of the two partition plates 6, an electric slide rail 8 is fixedly connected. A baffle 10 is installed on the electric slide rail 8, and a through hole 9 is formed in the inner wall of the chassis 1 and located inside the middle small chamber to allow the air inside the small chamber to communicate with the outside. The electric slide rail 8 drives the baffle 10 to move to block the through hole 9. When the device is idle, the filter element 304 is cleaned, and air passes through the through hole 9 to avoid the growth of mildew.

[0028] In this embodiment, the laser cutting mechanism 2 includes an X-axis electric slide rail 201, a Y-axis electric slide rail 202, a Z-axis electric slide rail 203, and an R-axis cutting machine 204. The X-axis electric slide rail 201 is installed on the inner wall of the chassis 1. The guiding block of the X-axis electric slide rail 201 is fixed with the Y-axis electric slide rail 202. The guiding block of the Y-axis electric slide rail 202 is installed with the Z-axis electric slide rail 203. The guiding block of the Z-axis electric slide rail 203 is connected to the R-axis cutting machine 204.

[0029] Working principle: The laser cutting mechanism 2 adopts a four-axis (X / Y / Z / R) linkage structure. Among them, the X / Y axes are responsible for planar movement, the Z-axis controls the height of the cutting head, and the R-axis realizes the rotary cutting of pipes or shaped workpieces. The R-axis uses a laser cutting machine with a cutting head that can rotate 360°. High-precision and non-blind-angle cutting of the processing parts is completed. When cutting metal materials, laser cutting will generate metal dust and acidic gases. The air pump in the installation box body 5 sends the metal dust and acidic gases into the purification area through the through pipe 7. The metal dust is filtered by the filter element 304, and the acidic gases are filtered by the alkaline solution provided in the cleaning liquid storage tank 401.

[0030] Due to the chemical characteristics of the alkaline solution itself with low corrosion to most metals, the corrosion of the internal structure of the chassis 1 is reduced. And the alkaline solution can saponify animal and vegetable oils and fats and neutralize acidic dirt. When the acidic gases pass through the filter element 304, the filter element 304 will absorb part of the acidic gases, and acidic dirt will be formed inside after a certain period of time. The alkaline solution has high permeability. Combining with the high-pressure flushing of the spray head 403 can thoroughly remove the metal powder blockage inside the filter element 304 while neutralizing the acidic dirt inside the filter element. Therefore, the set alkaline solution has the advantages of high-efficiency decontamination, structural protection, environmental protection and energy saving, etc. through mechanisms such as chemical decomposition, physical penetration, and ion chelation when cleaning the metal powder filter element.

[0031] The alkaline solution after subsequent flushing is stored inside the storage tank 13 through the drain tank 12, while the filtered high-temperature gas is discharged into the alkaline solution through the third pipeline 502. After the high-temperature acidic gas reacts chemically with the alkaline solution for neutralization, the gas detector 15 can detect the acidic content in the waste gas. After reaching the emission standard, it is discharged through the pipeline opening 16 provided at the upper part, and the pipeline opening 16 at the bottom is used to connect to the water pump to discharge the waste liquid, completing the purification of the gas and ensuring the working environment of the workshop.

[0032] After using for a certain period of time, during the interval when the equipment cuts the next workpiece, the filter element 304 connected to the through pipe 7 can be rotated and replaced in position by the electric rotating disc 302, thus completing the replacement of the filter element 304. There are multiple filter elements 304 and they are automatically replaced, so that during long-term operation of the equipment, there is no need to manually replace the filter element, improving the processing efficiency and ensuring the workshop environment.

[0033] After the filter element 304 absorbs a certain amount of metal powder and needs to be replaced and cleaned, the filter element 304 connected to the through pipe 7 is rotated and replaced in position by the electric rotating disc 302. Then, the filter element 304 located outside is moved inward by the screw-type electric slide rail 305 to approach the cleaning shaft 303. Then, the micro motor 301 drives the filter element 304 and the cleaning shaft 303 with protrusions on the outside to rotate and rub against each other. At the same time, the cleaning liquid storage tank 401 puts high-concentration alkaline solution into the box body 402, mixes it with a certain amount of clear water and stirs it, and the cleaning liquid is sprayed on the filter element 304 driven by the spray head 403. The filter element 304 and the cleaning shaft 303 rub against each other to clean the attached metal powder on it. Then, the filter element 304 is reset, and the micro motor 301 drives the filter element 304 to rotate to throw out the internal moisture. The baffle 10 is moved downward by the electric slide rail 8 to ventilate and dry the filter element 304. The filter element 304 can be automatically cleaned and replaced without manual input.

[0034] As Figure 1 shown, a disassembly plate is provided on the chassis 1. After disassembly, the filter element 304 can be directly replaced. The provided bracket 308 is fixed to the chassis 1 by bolts. After removing the bracket 308, and then removing the clamping shaft 307, the filter element can be taken out, which is convenient for replacement and improves the practicality of the equipment.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
