Description

Technical Field

[0001] This utility model relates to the field of CNC equipment technology, specifically to a CNC mechanical device. Background Technology

[0002] CNC (Computer Numerical Control) machinery is a widely used automated processing equipment in modern manufacturing. It can process various materials efficiently and accurately. Common CNC machinery includes CNC milling machines, CNC lathes, CNC laser cutting machines, CNC waterjet cutting machines, CNC EDM machines, CNC engraving machines, CNC laser marking machines, CNC composite machines, and CNC 3D printers.

[0003] A patent with publication number CN218050879U discloses a laser cutting machine, belonging to the field of laser cutting. It includes a mounting plate on which a laser emitter is mounted. A connecting plate is located on one side of the bottom of the mounting plate. A hollow plate is located on the side of the connecting plate near the mounting plate. A connecting block is connected to the side of the connecting plate away from the hollow plate. A processing box is mounted on the side of the connecting block away from the hollow plate. A suction pump is installed on the top of the connecting plate. The inner cavity of the processing box is divided into a dust chamber and a filter chamber. A baffle is connected to the top of the inner cavity of the dust chamber. During laser cutting, exhaust gas and dust generated are drawn into the processing box by the suction pump. The dust and exhaust gas enter the dust chamber. The exhaust gas passes through a filter, while the dust remains in the dust chamber. The exhaust gas then enters the filter chamber, is purified by activated carbon, and is discharged, reducing dust and exhaust gas in the air, improving the working environment for workers, and reducing hazards to workers.

[0004] The aforementioned laser cutting machine relies on filters and activated carbon to purify the dust sucked into the dust chamber. During the dust filtration process, the mesh of the filter will gradually become clogged with dust, which will slowly reduce the filtration quality and dust removal effect. The filter cannot maintain cleanliness during operation, which leads to a certain degree of reduction in dust removal effect. Utility Model Content

[0005] The purpose of this invention is to provide a CNC machine tool that solves the problem that existing CNC machine tools rely on filters and activated carbon to purify dust drawn into the dust chamber during processing. However, the filters gradually become clogged with dust during the dust filtration process, and the filters cannot maintain cleanliness during operation, which reduces the dust removal effect to some extent.

[0006] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes:

[0007] Equipment platform, with a Z-axis movable frame installed above the equipment platform;

[0008] The self-cleaning assembly is located above the movable frame. It includes a dust removal box and a water tank. Inside the dust removal box, two rotating rollers are mounted, each with a motor fixed to one end. Both motors are fixed to one side of the dust removal box. Inside the dust removal box, a traction roller is fixed. A fine filter screen is wound between the two rollers. Inside the dust removal box, two vertically aligned double pipes are fixed, each with multiple nozzles fixed to its exterior. Inside the dust removal box, two opposing dust-cleaning strips are fixed. On one side of the dust removal box, two water supply hoses are fixed, each extending one end into the water tank.

[0009] Preferably, the ash removal box has two heating and drying plates fixed inside, and the two heating and drying plates are respectively arranged on both sides of the filter screen.

[0010] Preferably, a drain hose is fixed below the ash removal box, and the drain hose is fixed to the back of the movable frame by a fixing bracket.

[0011] Preferably, an air pump is fixed to the back of the ash removal box, and two telescopic pipes are fixed to the front of the ash removal box, with two suction heads fixed to one end of each of the two telescopic pipes.

[0012] Preferably, an X-axis moving frame is installed above the moving frame, a Y-axis moving frame is installed in front of the X-axis moving frame, a lifting platform is installed in front of the Y-axis moving frame, and a laser cutting head is fixed below the lifting platform.

[0013] Preferably, both suction heads are fixed to both sides of the lifting platform via connecting frames.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The filter screen is periodically rotated by a motor and two rollers, releasing the clean sections for use and rewinding the clogged sections. Before being released again, the clogged sections pass through dual pipes and cleaning strips to remove dust from the filter screen. The wastewater is then discharged through a drain hose, ensuring that the filter screen remains clear and clean throughout its use, achieving self-cleaning and preventing clogging caused by prolonged dust filtration, which could affect the dust removal effect.

[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] This embodiment provides a technical solution: a CNC mechanical device, such as... Figure 1-3 As shown, the device includes a device platform 1 and a self-cleaning component 3. A Z-axis moving frame 2 is installed above the device platform 1, an X-axis moving frame 4 is installed above the Z-axis moving frame 2, a Y-axis moving frame 5 is installed in front of the X-axis moving frame 4, a lifting platform 6 is installed in front of the Y-axis moving frame 5, and a laser cutting head 7 is fixed below the lifting platform 6. The cutting position of the laser cutting head 7 can be flexibly adjusted by means of the Z-axis moving frame 2, the Y-axis moving frame 5 and the X-axis moving frame 4.

[0023] The self-cleaning assembly 3 is positioned above the Z-axis moving frame 2. The self-cleaning assembly 3 includes a dust removal box 31 and a water tank 310, both positioned above the Z-axis moving frame 2. The dust removal box 31 is fixed to the Y-axis moving frame 5 and can later move with the laser cutting head 7. Inside the dust removal box 31, two rotating rollers 32 are positioned one above the other inside the dust removal box 31. A motor 33 is fixed to one end of each roller 32 and is fixed to one side of the dust removal box 31, driving the rollers 32 to rotate. A traction roller 34 is fixed inside the dust removal box 31, restricting the turning point of the filter screen 35. The filter screen 35 is wound between the outer surfaces of the two rollers 32. Inside the dust removal box 31, two vertically aligned double pipes 36 are fixed, divided into left and right pipes for filtering... The fine screen 35 passes through the inside of the two double pipes 36. Multiple nozzles 37 are fixed to the outside of the two double pipes 36. Two opposing cleaning strips 38 are fixed inside the ash removal box 31. The two cleaning strips 38 are set between the two double pipes 36. Two water supply hoses 39 are fixed to one side of the ash removal box 31. One end of each water supply hose 39 extends into the water tank 310 and is connected to a water pump. Water is delivered to the water supply hoses 39 by the water pump. Both water supply hoses 39 can be fixed to the Z-axis moving frame 2 by positioning rings. Two heating drying plates 311 are fixed inside the ash removal box 31. Heating tubes are installed inside the heating drying plates 311. The heating drying plates 311 are connected to the external control switch by existing technology. The two heating drying plates 311 are respectively set on both sides of the filter fine screen 35.

[0024] A drain hose 312 is fixed at the bottom of the ash removal box 31 to discharge the sewage inside the ash removal box 31. The drain hose 312 is fixed to the back of the Z-axis moving frame 2 by a fixing bracket. One end of the drain hose 312 can be connected to a water collection tank for collecting sewage. An air pump 313 is fixed to the back of the ash removal box 31. An exhaust pipe is fixed to the air outlet end of the air pump 313. A filter screen is provided at one end of the exhaust pipe to prevent external dust and impurities from entering. Two telescopic pipes 314 are fixed to the front of the ash removal box 31. The telescopic pipes 314 are set so that the dust suction head 315 can always be connected to the ash removal box 31 when it rises and falls with the lifting platform 6. Two dust suction heads 315 are fixed to one end of each of the two telescopic pipes 314. Both dust suction heads 315 are fixed to both sides of the lifting platform 6 by a connecting bracket.

[0025] During use, the workpiece is placed on the equipment platform 1. The cutting position of the laser cutting head 7 is flexibly adjusted by the Z-axis moving frame 2, Y-axis moving frame 5, and X-axis moving frame 4. The laser cutting head 7 is used to cut the workpiece. During cutting, the air pump 313 is started. The air pump 313 draws the dust and impurities generated during cutting into the dust removal box 31 through the dust suction head 315 and the telescopic tube 314. The dust is intercepted by the fine filter screen 35 to prevent it from entering the air pump 313. The filtered air is discharged through the exhaust pipe. During the start-up of the air pump 313, the start and stop time of the motor 33 is set at regular intervals. The motor 33 drives the roller 32 connected to it to change the position of the fine filter screen 35. The clean parts are released to continue filtering air, while the dirty parts are rolled up to prevent the fine filter screen 35 from clogging due to prolonged dust filtration, which would affect the efficiency of subsequent dust suction.

[0026] When the upper roller 32 releases the filter screen 35 and the lower roller 32 retracts it, the nozzle 37 and the heating and drying plate 311 are closed. Conversely, when the lower roller 32 releases the filter screen 35 and the upper roller 32 retracts it, the nozzle 37 and the heating and drying plate 311 are open. The nozzle 37 draws water from the water tank 310 to the dual pipe 36 through the water delivery hose 39, and sprays the water onto the filter screen 35 through the nozzle 37. The dust on the filter screen 35 is scraped off when it passes through two cleaning strips 38. Then it is cleaned again by the nozzles 37 on the double pipes 36 to improve the cleaning quality. After cleaning, the filter screen 35 is dried by two heating drying plates 311 to avoid the presence of water stains causing a large amount of dust to adhere to the filter screen 35, which would make it difficult for the cleaning strips 38 to scrape it later. The water sprayed from the nozzles 37 will be discharged through the drain hose 312 to prevent sewage from accumulating in the dust removal box 31 and contaminating the filter screen 35.

[0027] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
