The first connecting pipe 404, the air inlet 403 and the vacuum cleaner 411 form a through connection. The threaded rod 409 and the nut 410 are threadedly connected. Before using the laser cutting machine, move the first half block 401 and the second half block 402 to the side of the cutting assembly 4 for fixing. When the first half block 401 and the second half block 402 are fixed, the two connecting blocks 405 can be driven to move. When the connecting block 405 moves, the threaded rod 409 can be moved to the side of the second movable groove 407.

Example

[0019] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the direct emission of smoke from the laser cutting machine will damage the environment and affect the health of the surrounding people, a filtering mechanism is disclosed: The filtering mechanism includes an electrostatic plate 413, a wire is connected to the side of the electrostatic plate 413, the electrostatic plate 413 is connected to the inside of the filter tower 412, an activated carbon plate 414 is connected to the inside of the filter tower 412 away from the electrostatic plate 413, a collecting box 415 is slidably connected to the bottom of the activated carbon plate 414, a spring 417 is connected to the inside of the filter tower 412, an extrusion groove 416 is opened at the bottom of the collecting box 415, the extrusion groove 416 and the spring 417 are symmetrically distributed about the filter tower 412, a telescopic groove 418 is symmetrically opened on the inner side of the filter tower 412, a first spring 419 is connected to the inside of the telescopic groove 418, a telescopic block 420 is connected to the bottom end of the first spring 419, the telescopic block 420 penetrates and slides inside the telescopic groove 418, and the telescopic block 420 is fixed on the electrostatic plate 4 13 side, a motor 421 is installed on the side of the filter tower 412, and a cam 422 is fixed on the output end of the motor 421. The cam 422 includes a rolling groove and a rolling wheel. The rolling wheel rotates inside the rolling groove. When the laser cutting machine is in use, the vacuum cleaner 411 can absorb and remove the smoke generated by the processing through the air inlet 403. After the vacuum cleaner 411 absorbs the smoke, it can discharge the smoke into the filter tower 412 through a pipe. The smoke can move from bottom to top inside the filter tower 412. When the smoke moves to the inside of the electrostatic plate 413, static electricity can be generated by energizing the wire. The static electricity generated by the electrostatic plate 413 can adsorb the dust particles in the smoke. When the smoke moves to the bottom of the activated carbon plate 414, it can adsorb organic compounds and odors in the smoke, and can further The step is to absorb the particulate matter, and the smoke after purification will reduce the harm to the environment after being discharged. When the electrostatic plate 413 of the laser cutting machine is used for a certain period of time, the surface will absorb more particles. First, the circuit of the electrostatic plate 413 is disconnected, and then the output end of the motor 421 is started to drive the cam 422 to rotate. When the cam 422 rotates, it can drive the internal rolling wheel to move. When the rolling wheel moves to the top of the electrostatic plate 413, it can be squeezed.

When the collecting box 415 is pulled, it can move inside the filter tower 412. When the collecting box 415 moves, it can drive the inner wall of the extrusion groove 416 to squeeze the inclined surface of the spring piece 417. When the spring piece 417 is squeezed, it can be deformed.When the spring piece 417 is deformed, the collection box 415 can slide out of the filter tower 412, and the particles in the collection box 415 can be dumped, thereby improving the sustainability of the filtration of the laser cutting machine. Example

[0020] like Figure 3 , Fig. 9 , Fig.10 and Fig.11 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the smoke filter mechanism of the laser cutting device will accumulate particles after long-term use, the filtering effect will be reduced, and it may also cause blockage and cannot be used, a detection mechanism is disclosed: The detection mechanism includes a gas detector 424, which is connected to the end of the second connecting pipe 423. An electric valve 425 is connected to the side of the gas detector 424. A third connecting pipe 426 is connected between the side of the electric valve 425 and the filter tower 412. Six groups of positioning blocks 427 are fixed to the end of the gas detector 424. Six groups of positioning grooves 428 are opened at the end of the second connecting pipe 423. Multiple groups of rotating grooves 429 are opened on the side of the second connecting pipe 423. A rotating block 430 slides through the rotating groove 429. A second spring 431 is connected between the rotating block 430 and the rotating groove 429. A fixing ring 432 is fixed to the top of the rotating block 430. A snap-fitting groove 433 is provided on the side of the detector 424, and a snap-fitting block 434 is slidably penetrated inside the snap-fitting groove 433. The snap-fitting block 434 is fixed on the side of the fixed ring 432. The laser cutting machine rotates the fixed ring 432 before discharging the smoke generated by cutting. When the fixed ring 432 rotates, it can drive the rotating block 430 to move. When the rotating block 430 moves, it can rotate through the rotating groove 429. When the rotating block 430 rotates, it can squeeze the second spring 431. At the same time, when the fixed ring 432 rotates, it can drive the snap-fitting block 434 to rotate. After the snap-fitting block 434 rotates to a certain position, it moves the second connecting tube 423. When the second connecting tube 423 moves, it can drive the positioning block 427 to move. When the positioning block 427 moves to the side of the positioning groove 428, it can be inserted. When the positioning block 427 is inserted, the gas detector 424 can slide to the end of the second connecting pipe 423. At this time, the first connecting pipe 404 can slide into the inside of the engaging groove 433. The fixing ring 432 is loosened and can be reset under the elastic force of the second spring 431. When the fixing ring 432 is reset, the engaging block 434 can be driven to reset. When the engaging block 434 is reset, it can be engaged and positioned with the engaging groove 433. When the engaging block 434 is positioned, it can drive the second connecting pipe 423 and the gas detector 424 to be installed. After the installation is completed, when the smoke filtered inside the filter tower 412 is discharged, the smoke can pass through The second connecting pipe 423 is transported to the inside of the gas detector 424, and the gas detector 424 can detect the exhausted smoke. When the smoke is qualified, it can be discharged through the left pipe. When the smoke is unqualified, the operating panel 3 can start the electric valve 425 to change the pipeline transportation direction, and the gas can be re-transported to the inside of the filter tower 412 through the third connecting pipe 426 for re-filtration. The unqualified gas detection may be caused by the electrostatic plate 413 adsorbing more and the reduced adsorption intensity. The operating panel 3 will automatically start the motor 421 to remove the adsorbed particles, reducing manual intervention. Re-filtration can improve the smoke filtering effect of the cutting machine and improve environmental protection.
