The outside of the processing workbench 14 is sleeved with a protective square cylinder 3. The top of the protective square cylinder 3 is higher than the processing workbench 14. When the workpiece that needs to be finely carved is mounted on the processing workbench 14, the workpiece is completely in the lower part of the inner cavity of the protective square cylinder 3 to prevent dust from flying out during the processing process.

[0025] The bottom end of the protective square tube 3 is fixedly installed with a connecting base 2, the bottom end of the connecting base 2 is fixedly installed with a supporting base 1, and one side of the top end of the supporting base 1 is fixedly installed with a mounting bracket 4, which is arranged on the back side of the protective square tube 3.

[0026] The top of the mounting bracket 4 is fixedly mounted with a main control box 5 of the engraving machine, the bottom of the main control box 5 is fixedly mounted with a tool driver 6, the bottom of the tool driver 6 is fixedly mounted with an engraving tool 7, and the engraving tool 7 is arranged above the processing workbench 14.

[0027] The tool driver 6 drives the fine carving tool 7 to rotate at high speed. The fine carving machine main control box 5 mainly controls the movement of the tool driver 6 in the three-dimensional space, which is convenient for comprehensive processing of the workpiece to be processed, and also controls the output speed of the tool driver 6.

[0028] A mounting connection frame 8 is fixedly installed on the bottom of the outer wall of the tool driver 6 , and a fixed connection arm 9 is fixedly connected to one side of the mounting connection frame 8 . An end of the fixed connection arm 9 away from the mounting connection frame 8 is provided with a mounting slot.

[0029] A dust collecting connecting groove 15 is provided at the top of the processing workbench 14, and a supporting column 16 is fixedly installed on the bottom groove wall of the dust collecting connecting groove 15. The top of the supporting column 16 is fixedly connected to a supporting workbench 17, and a protective mesh plate 18 is fixedly installed on the top of the outer wall of the supporting workbench 17.

[0030] The carrying workbench 17 is flush with the top surface of the processing workbench 14 and has no contact with the side wall of the dust collecting connection groove 15. The protective mesh plate 18 is arranged between the outer wall of the carrying workbench 17 and the inner wall of the dust collecting connection groove 15 to facilitate the processing dust to pass through the protective mesh plate 18 and enter the interior of the dust collecting connection groove 15.

[0031] like Figure 2 As shown in the cross-section of the processing workbench 14 , the dust collecting connecting groove 15 is configured to be annular, and the width of the top of the dust collecting connecting groove 15 is smaller than the width of the bottom.

[0032] A plurality of air outlet connecting pipes 19 are fixedly connected at equal intervals to the bottom of one side of the processing workbench 14. The air outlet connecting pipes 19 are connected to the dust collecting connecting groove 15, and one end of the air outlet connecting pipe 19 is away from the processing workbench 14 and extends outward from the pipe mixing protection square cylinder 3, and an air exhaust guide pipe 20 is fixedly installed at the extended end.

[0033] Multiple exhaust ducts 20 are fixedly connected to the dust filter box 21 at one end away from the processing workbench 14. A dust filter screen 22 is fixedly installed inside the dust filter box 21 to filter the airflow entering the dust filter box 21. A protective baffle 23 is fixedly installed at the bottom of the dust filter box 21 away from the processing workbench 14 to facilitate dust discharge.

[0034] The top of the dust filter box 21 is fixedly connected with multiple air guide connecting pipes 24 at equal intervals, and the tops of the multiple air guide connecting pipes 24 are fixedly installed with micro air pumps 25.

One end of the ventilation connecting hose 11 is fixedly installed with a directional jet head 10, and the top of the directional jet head 10 is fixedly installed inside the mounting groove, and the air outlet of the directional jet head 10 is aligned with the tool head of the precision carving tool 7.

[0036] Working principle:

[0037] Please refer to Figures 1 to 4 , assemble the device as shown in the figure;

[0038] When the device is in use, the workpiece to be processed is first fixed on the top of the carrying workbench 17, and then multiple micro-exhaust pumps 25 are started. The micro-exhaust pumps 25 draw the airflow inside the protective square cylinder 3 into the dust collecting connecting groove 15. The airflow then enters the dust filter box 21 through the air outlet connecting pipe 19 and the air extraction guide pipe 20, and then passes through the dust filter screen 22, enters the air guide connecting pipe 24, and then enters the six-way connecting pipe 13. Finally, it converges in the directional air jet head 10 and blows towards the cutter head of the fine carving tool 7; then the fine carving machine main control box 5 is started, and the fine carving machine main control box 5 drives the fine carving tool 7 to process the workpiece to be processed through the tool driver 6; the dust generated on the surface of the workpiece to be processed is entrained by the airflow into the dust filter box 21 for filtration and collection, and finally the protective baffle 23 is opened for centralized discharge.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
