[0015] The detection method of a CNC plasma cutting machine is characterized by comprising the following steps: S1: When the cutting machine is used for a long time, the cutting component will heat up, thereby affecting the cutting state and operating life. During the cutting process, the output end of the double-headed motor is started to drive the first bevel gear rod to rotate. When the first bevel gear rod rotates, one end can rotate through the first fixed block. When the first bevel gear rod rotates, it drives the second bevel gear rod to mesh and rotate. When the second bevel gear rod meshes and rotates, it can drive the impeller inside the first manual pump to rotate, thereby generating an air pressure difference. The air pressure difference can draw the cooling water inside the water tank through the water inlet of the first manual pump into the first manual pump, and then transport it to the surrounding pipe through the first connecting pipe. The heat generated by the operation of the cutting machine will be absorbed by the connecting tube, which will be transferred to the surrounding pipe after absorption. The cooling water can absorb the heat when passing through the surrounding pipe. After absorbing the heat, the cooling water can be transported back to the water tank through the second connecting pipe. In this way, the circulation of cooling water is realized, which can effectively cool down the cutting component of the device. At the same time, the first bevel gear rod The other end can drive the third bevel gear rod to rotate. When the third bevel gear rod rotates, it can rotate through the second fixed block. At the same time, the second fixed block can drive the impeller inside the second manual pump to rotate. When the impeller of the second manual pump rotates, an air pressure difference can be generated. The air pressure difference can extract the gas inside the filter box through the air inlet of the second manual pump, and the gas is discharged through the air outlet of the second manual pump. After the gas inside the filter box is extracted, the gas is extracted through the third connecting pipe and the ventilation ring. When the ventilation ring extracts the gas, it can absorb the smoke generated by the cutting of the cutting component. After the smoke is absorbed into the filter box, the gas will turn quickly and be discharged through the air outlet of the second manual pump. The cutting smoke contains gas and solid particles. Since the mass of the particles is greater than that of the gas, when they turn inside the filter box, they will fall into the sterilizing water inside the filter box for precipitation, and the sterilizing water will also absorb other harmful substances in the gas, thereby reducing the harm and pollution caused by the smoke of the cutting machine; S2: Before using the filter box of the cutting machine, move the activated carbon filter plate to the side of the slot for insertion. When the activated carbon filter plate moves, it can drive the external block to move. When the activated carbon filter plate is inserted into the slot, it pushes the sliding block upward. When the sliding block is pushed up, it can slide through the sliding groove. When the sliding block slides, it can squeeze the spring through the sliding groove. After the sliding block is squeezed to a certain position, the activated carbon filter plate can be inserted into the slot. At this time, the activated carbon filter plate is located at the bottom of the air outlet of the filter box. The sliding block can be reset by the elastic force of the spring itself when it is released. When the sliding block is reset, it can be moved to the side of the external block to limit the position. When the external block is positioned, it can drive the activated carbon filter plate to be positioned. When the second manual pump extracts harmful gases to be discharged, the harmful gases can first pass through the sterilized water inside the filter box, and then pass through the activated carbon filter plate. The activated carbon filter plate can filter the gas more tightly before it can be discharged through the air outlet of the second manual pump, further reducing the harm caused by the cutting gas. S3: During the cutting process, the cutting component and the movable component will move continuously. When the movable component moves, it will drive the filter box to move. When the filter box moves, the liquid inside will swing. The swing of the liquid will drive the disc to swing. When the disc swings, it can drive the first rotating block to rotate. When the first rotating block rotates, it can rotate through the rotating groove. When the first rotating block rotates, it can drive the third rotating block to rotate. When the third rotating block rotates to the side of the extrusion block, it can be extruded. When the extrusion block is extruded, it can drive the second rotating block to rotate. When the second rotating block rotates, it can drive the rotating block to rotate. The rotating block can rotate through the rotating groove. When the rotating block rotates, the torsion spring can be tightened. After the torsion spring is tightened to a certain position, the third rotating block can be rotated out of the side of the extrusion block. At this time, the second rotating block can be reset by the elastic force of the torsion spring itself. When the second rotating block is reset, it can drive the hammer block to hit the bottom of the activated carbon filter plate. When the activated carbon filter plate is hit, the filtered particles will fall into the sterilizing water of the filter box, thereby realizing the cleaning of the activated carbon filter plate. After the activated carbon filter plate is cleaned, the efficiency of filtering harmful gases can be guaranteed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The CNC plasma cutting machine and its use method, because the particles are heavier than the gas, they will fall into the sterilized water inside the filter box when turning inside the filter box for precipitation, reducing the harm and pollution caused by the smoke of the cutting machine. The activated carbon filter plate can filter the harmful gas more tightly, further reducing the harm caused by the cutting gas. The activated carbon filter plate can be cleaned by the impact of the hammer block, ensuring the filtering effect; 2. A first bevel gear rod is provided, through which the first bevel gear rod can drive the first manual pump and the second manual pump at the same time. One driving device completes two functions, which can reduce the production cost of the cutting machine; 3. A ventilation ring is provided. The shape of the ventilation ring can absorb the smoke and dust generated during the cutting process of the cutting machine in a large range, reduce the existence of dead corners, and improve the air quality of the cutting environment; 4. An activated carbon filter plate is provided, through which smoke can be filtered for a second time, thus improving the smoke filtering effect of the cutting machine; 5. A disc is provided, through which the activated carbon filter plate can be cleaned without the need for a driving device, thereby ensuring the filtering effect of the activated carbon filter plate and making it more convenient to use.

10. A detection method for a CNC plasma cutting machine according to claim 9, characterized in that: The steps include: S1: When the cutting machine is used for a long time, the cutting assembly (4) will heat up, thereby affecting the cutting state and operating life. During the cutting process, the output end of the double-headed motor is started to drive the first bevel gear rod (302) to rotate. When the first bevel gear rod (302) rotates, one end can rotate through the first fixed block (303). When the first bevel gear rod (302) rotates, it drives the second bevel gear rod (305) to mesh and rotate. When the second bevel gear rod (305) meshes and rotates, it can drive the impeller inside the first manual pump (304) to rotate, thereby generating an air pressure difference. The air pressure difference can pump the cooling water inside the water tank (301) through the first manual pump. The water inlet of (304) is drawn into the first manual pump (304), and then transported to the surrounding tube (308) through the first connecting tube (306). The heat generated by the operation of the cutting machine will be absorbed by the connecting tube (307), and the connecting tube (307) will transfer the heat to the surrounding tube (308). The cooling water can absorb the heat when passing through the surrounding tube (308). After absorbing the heat, the cooling water can be transported back to the water tank (301) through the second connecting tube (309). In this way, the circulation of cooling water is realized, and the cutting component (4) of the device can be effectively cooled. At the same time, the first bevel gear The other end of the rod (302) can drive the third bevel gear rod (312) to rotate. When the third bevel gear rod (312) rotates, it can rotate inside the second fixed block (313). At the same time, the second fixed block (313) can drive the impeller inside the second manual pump (311) to rotate. When the impeller of the second manual pump (311) rotates, a pressure difference can be generated. The pressure difference can extract gas inside the filter box (310) through the air inlet of the second manual pump (311), and the gas is discharged through the air outlet of the second manual pump (311). After the gas inside the filter box (310) is extracted, it will pass through the third connecting pipe ( 314) and the ventilation ring (315) extract gas. When the ventilation ring (315) extracts gas, it can absorb the smoke generated by the cutting of the cutting component (4). After the smoke is absorbed into the filter box (310), the gas will quickly turn and be discharged through the outlet of the second manual pump (311). The cutting smoke contains gas and solid particles. Since the particles are heavier than the gas, they will fall into the sterilizing water inside the filter box (310) when turning inside the filter box (310) to precipitate. The sterilizing water will also absorb other harmful substances in the gas, thereby reducing the harm and pollution caused by the smoke of the cutting machine; S2: Before using the filter box (310) of the cutting machine, move the activated carbon filter plate (317) to the side of the slot (316) for insertion. When the activated carbon filter plate (317) moves, it can drive the external block (318) to move. When the activated carbon filter plate (317) is inserted into the slot (316), it pushes the sliding block (320) upward. When the sliding block (320) is pushed upward, it can slide through the sliding groove (319). When the sliding block (320) slides, it can squeeze the spring through the sliding groove (319). After the sliding block (320) is squeezed to a certain position, the activated carbon filter plate (317) can be completely inserted into the slot (316). At this time, the activated carbon filter plate (317) Located at the bottom of the air outlet of the filter box (310), the sliding block (320) can be reset by the elastic force of the spring by releasing it. When the sliding block (320) is reset, it can be moved to the side of the external block (318) to limit the position. When the external block (318) is positioned, it can drive the activated carbon filter plate (317) to be positioned. When the second manual pump (311) extracts harmful gases for discharge, the harmful gases can first pass through the sterilized water inside the filter box (310) and then pass through the activated carbon filter plate (317). The activated carbon filter plate (317) can filter the gas more tightly before it can be discharged through the air outlet of the second manual pump (311), thereby further reducing the harm caused by the cutting gas. S3: During the cutting process, the cutting assembly (4) and the movable assembly (3) will move continuously. When the movable assembly (3) moves, it will drive the filter box (310) to move. When the filter box (310) moves, the liquid inside will swing. The swing of the liquid will drive the disc (330) to swing. When the disc (330) swings, it can drive the first rotating block (322) to rotate. When the first rotating block (322) rotates, it can rotate through the rotating groove (321). When the first rotating block (322) rotates, it can drive the third rotating block (328) to rotate. When the third rotating block (328) rotates to the side of the squeezing block (329), it can be squeezed. When the squeezing block (329) is squeezed, it can drive the second rotating block (323) to rotate. When the second rotating block (323) rotates, it can drive the rotating block (328). The rotating block (324) rotates, and the rotating block (324) can rotate through the rotating groove (321). The rotating block (324) can tighten the torsion spring (325) at the same time. After the torsion spring (325) is tightened to a certain position, the third rotating block (328) can rotate out of the side of the extrusion block (329). At this time, the second rotating block (323) can be reset by the elastic force of the torsion spring (325). When the second rotating block (323) is reset, it can drive the hammer block (326) to hit the bottom of the activated carbon filter plate (317). When the activated carbon filter plate (317) is hit, the filtered particles will fall into the sterilizing water in the filter box (310), thereby achieving the cleaning of the activated carbon filter plate (317). After the activated carbon filter plate (317) is cleaned, the efficiency of filtering harmful gases can be guaranteed.
