[0002] The precision engraving machine is a CNC machine tool that integrates high-precision cutting, micro-machining and three-dimensional engraving. It is essentially a sub-type of high-end CNC machining center, with a precision that can reach the micron level. It is specially used for the processing and manufacturing of complex and precision parts.

[0003] Existing CNC engraving machines typically expose their worktables to the external environment during operation. During engraving, debris from the workpiece or accidental tool breakage can easily scatter into the surrounding environment, potentially causing injury to workers. This results in poor safety protection. Furthermore, engraving debris remains on the workpiece or worktable, and some debris even drifts into the surrounding environment, making cleanup difficult and reducing overall efficiency. Therefore, we propose a CNC engraving machine with protective features. Utility Model Content

[0010] A filter box is installed on one side of the housing. An air inlet slot is provided on the bottom side of the filter box and the bottom side of the housing. The two air inlet slots are connected end to end. Several filter screens are also installed inside the filter box. The air inlet end of the circulation pump is connected to the suction pipe, and the other end of the suction pipe is fixed to the top of the filter box.

[0011] Preferably, the adjustment structure includes a first linear drive module connected to both sides of the box via a track, a crossbeam connecting the two first linear drive modules, a second linear drive module mounted on the side of the crossbeam, a third linear drive module connected to one side of the second linear drive module via a strip mounting plate, and one side of the third linear drive module connected to an L-shaped fixing plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A precision engraving machine with protective function includes a base 1, a box 6 with an opening on one side is installed on the top of the base 1, a control cabinet 28 is installed on one side of the box 6, and a controller is installed inside the control cabinet 28. The controller is either a control motherboard or a PLC logic controller.

[0028] like Figure 3 and Figure 5As shown, an L-shaped fixing plate 11 is connected to the interior of the housing 6 via an adjustment mechanism. A carving blade 12 is rotatably connected to the bottom of the L-shaped fixing plate 11, and the top of the carving blade 12 is connected to a drive motor 10. The drive motor 10 is fixed to the top of the L-shaped fixing plate 11. The adjustment mechanism includes a first linear drive module 20 connected to both sides of the interior of the housing 6 via a track. A crossbeam 22 connects the two first linear drive modules 20. A second linear drive module 27 is mounted on the side of the crossbeam 22. One side of the second linear drive module 27 is connected via... The strip mounting plate 23 is connected to the third linear drive module 29. One side of the third linear drive module 29 is connected to the L-shaped fixing plate 11. The first linear drive module 20, the second linear drive module 27, the third linear drive module 29 and the drive motor 10 are all connected to the controller through wires. In actual use, the position of the engraving knife 12 can be adjusted by the first linear drive module 20, the second linear drive module 27 and the third linear drive module 29. After adjustment, the drive motor 10 can drive the engraving knife 12 to rotate and engrave the workpiece.

[0029] It should be noted that, as Figure 1 As shown, a workbench 14 is installed inside the housing 6. The workbench 14 is located below the carving knife 12. In actual use, the operator can install the workpiece to be carved on the workbench 14 and then carry out the carving process using the carving knife 12.

[0030] like Figure 1 As shown, U-shaped limiting strips 3 are symmetrically installed at one end of the box body 6 near the opening. The opening directions of the two U-shaped limiting strips 3 are opposite to each other, and a protective cover plate 4 is provided between the two U-shaped limiting strips 3. Both sides of the protective cover plate 4 extend into the corresponding U-shaped limiting strips 3. In actual use, the protective cover plate 4 can be limited by the U-shaped limiting strips 3, so that the protective cover plate 4 remains stable.

[0031] like Figure 2 As shown, a strip connecting plate 5 is installed on one side of the top of the protective cover plate 4. The bottom of the strip connecting plate 5 is connected to the top of the box 6 through a telescopic mechanism 16. The telescopic mechanism 16 is one of an electric push rod, a cylinder, or a hydraulic rod, and the telescopic mechanism 16 is connected to the controller through a wire. In actual use, the telescopic mechanism 16 can drive the protective cover plate 4 to move, so that the protective cover plate 4 can block the opening of the box 6. In this way, during the engraving process, the engraving chips will not splash onto the user. In addition, when the engraving knife 12 is subjected to excessive force and breaks, the engraving knife 12 will not fly out of the box 6 and injure the staff, thus improving the use effect.

[0032] It should be noted that, as Figure 1As shown, a strip groove 15 is provided on one side of the top of the base 1. When the protective cover 4 is moved to the bottom, the bottom of the protective cover 4 extends into the strip groove 15. In actual use, the bottom of the protective cover 4 can be stored through the strip groove 15, which will make the protective cover 4 fully contact the side wall of the box 6. During use, the chips generated by carving will not leak from the gap between the bottom of the protective cover 4 and the box 6.

[0033] It should be noted that the protective cover 4 is made of transparent plastic or other hard transparent material. This way, even when the protective cover 4 blocks the opening of the box 6, the staff can still observe the engraving of the workpiece inside the box 6 through the protective cover 4.

[0034] like Figure 3 and Figure 4 As shown, a circulation pump 18 is installed on the top of the housing 6. The outlet of the circulation pump 18 is connected to a first delivery pipe 7. A diversion pipe 8 is installed at the other end of the first delivery pipe 7. Several second nozzles 21 are installed on one side of the diversion pipe 8. One end of each second nozzle 21 extends into the housing 6. The circulation pump 18 is connected to a controller via a wire. A second delivery pipe 19 is also installed on one side of the first delivery pipe 7. The other end of the second delivery pipe 19 is connected to an air guide pipe 25 via a pipe joint. A fixing block 24 is installed on one side of the fixing plate 11. A first nozzle 9 is installed at the bottom of the fixing block 24. The top of the first nozzle 9 is connected to the air guide pipe 25. The bottom of the first nozzle 9 faces the end of the carving knife 12. A filter box 2 is installed on one side of the box body 6. An air inlet groove 13 is opened on the bottom side of the filter box 2 and the bottom side of the box body 6. The two air inlet grooves 13 are connected end to end. Several filter screens 26 are also installed inside the filter box 2. The air inlet end of the circulation pump 18 is connected to the suction pipe 1. 7. The other end of the suction pipe 17 is fixed to the top of the filter box 2. In actual use, the circulation pump 18 can draw out the gas in the filter box 2 through the suction pipe 17 and deliver it to the second delivery pipe 19 and the diversion pipe 8 through the first delivery pipe 7. The gas in the diversion pipe 8 can be sprayed to the bottom of the box 6 through the second nozzle 21, while the air in the second delivery pipe 19 can be delivered to the first nozzle 9 through the air guide pipe 25 and sprayed to the carving position of the carving knife 12 through the first nozzle 9 to blow away the carving debris. At the same time, the gas in the filter box 2 is drawn out, and a negative pressure is generated inside the filter box 2, which causes the air inlet 13 to generate suction, and the debris blown away by the first nozzle 9 and the second nozzle 21 is drawn into the filter box 2. Then the debris is filtered out by the filter screen 26, and the pure air passes through the filter screen 26 and is drawn in by the suction pipe 17 and delivered to the first delivery pipe 7 through the circulation pump 18 for recycling. In this way, the carving debris will eventually be collected in the filter box 2, which is easy to clean.

[0035] Specifically, in use, the worker fixes the workpiece to be engraved on the worktable 14, and then controls the telescopic mechanism 16 to work through the controller. The telescopic mechanism 16 moves the protective cover plate 4 through the strip connecting plate 5, so that the bottom of the protective cover plate 4 moves into the strip groove 15, blocking the opening of the box 6. Then the controller controls the first linear drive module 20, the second linear drive module 27, the third linear drive module 29 and the drive motor 10 to work. The drive motor 10 drives the engraving knife 12 to rotate, and at the same time the first linear drive module 20, the second linear drive module 27, and the third linear drive module 29 drive the engraving knife 12 to move, thus engraving the workpiece. The cooperation between the protective cover plate 4 and the box 6 can form a sealed space, so that the debris generated during the engraving process or the fragments generated by the breakage of the engraving knife 12 during the engraving process will not fly out to the outside and injure the worker, thus improving the protection effect. In addition, during the engraving process, the worker controls the circulation. Pump 18 operates, and the circulating pump 18 draws gas out of the filter box 2 through the suction pipe 17, creating a negative pressure inside the filter box 2. This, in turn, causes the air inlet 13 to generate suction, drawing gas from the box 6 into the filter box 2. The gas drawn in through the suction pipe 17 is then transported through the first delivery pipe 7 to the second delivery pipe 19 and the diversion pipe 8. The air in the diversion pipe 8 is sprayed through the second nozzle 21 towards the bottom of the box 6, blowing away the debris remaining at the bottom of the box 6. Simultaneously, the air in the second delivery pipe 19 is transported through the air guide pipe 25 to the first nozzle 9, and then sprayed through the first nozzle 9 towards the end of the engraving knife 12, blowing away the debris from the engraving area of ​​the workpiece. The blown debris is carried by the airflow and drawn into the filter box 2 by the air inlet 13. The gas is then filtered by the filter screen 26, which blocks the debris in the gas. The clean air passes through the filter screen 26 and is drawn in by the suction pipe 17 for recycling. This allows for the concentrated collection of engraving debris, improving the efficiency of the process.

[0036] Furthermore, such as Figure 4 As shown, the filter screen 26 is located between the air inlet slot 13 and the air intake pipe 17. The air entering the filter box 2 from the air inlet slot 13 will be filtered by the filter screen 26 before being drawn in by the air intake pipe 17, ensuring thorough filtration.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
