[0002] A CNC wood carving machine is a machine that automatically carves wood, boards, plastics and other materials. It is operated by a computer control system that can automatically control the movement of the cutting tools to complete the carving work. Compared with traditional manual carving, CNC carving machines have the advantages of high efficiency, high precision and high repeatability.

[0003] However, during the engraving process, the cutting tool continuously moves across the surface of the material, generating constant debris. To quickly remove this debris, a suction tube is installed on the head of the engraving machine, with the other end connected to a dust collection device. While the suction tube removes most of the debris, larger pieces and those in crevices remain, leaving residue in the gaps of the design. Therefore, we propose a debris cleaning device for CNC engraving machines. Utility Model Content

[0018] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1 to 4 This utility model provides a technical solution: a chip cleaning device for a CNC engraving machine, including a second mounting frame 7 and a first mounting frame 8. The first mounting frame 8 has a mounting pipe 9 on one side, and an air blowing head 11 is installed at the bottom of the mounting pipe 9. The top of the mounting pipe 9 is connected to an air supply device 2 via a pipe, and the air supply device is a high-pressure air pump. Figure 1 As shown, the bottom of the mounting tube 9 is connected to the air head 11 via the positioning tube 10. The positioning tube 10 is a universal bamboo tube or a gooseneck tube, which allows the angle of the air head 11 to be adjusted at will. That is, both the universal bamboo tube and the gooseneck tube can rotate at any angle, so the blowing direction can be adjusted at will after the air head is set on its end.

[0020] In practical applications, both the second mounting bracket 7 and the first mounting bracket 8 are mounted on the head of the engraving machine tool, such as... Figure 3 As shown, the second mounting bracket 7 and the first mounting bracket 8 are symmetrically arranged, and a dust suction hood 1 with an opening facing the air blowing head 11 is provided below the second mounting bracket 7. Two support shafts 6 are symmetrically installed on the top of the dust suction hood 1. The top of the support shafts 6 is movably arranged in the guide seat 5, and the guide seat 5 is installed on the second mounting bracket 7.

[0021] like Figure 1 and Figure 2 As shown, the tops of the support shaft 6 and the mounting tube 9 are movably placed inside the guide seat 5. The two guide seats 5 are respectively mounted on the second mounting bracket 7 and the first mounting bracket 8. Fasteners, specifically bolts, are provided on the guide seats 5. The support shaft 6 and the mounting tube 9 can be adjusted in height along the guide seat 5. Once the height is adjusted, they can be positioned by bolts.

[0022] Specifically, the end of the dust hood 1 furthest from the blower head 11 is connected to the dust collection device via a pipe, such as... Figure 3 As shown, the vacuuming device includes a collection bin 14, with a detachable lid on top. The lid is connected to the collection bin 14 via a latch. At least one vent 13 is provided on the top of the lid, and a filter screen is installed inside each vent 13.

[0023] The top of the bucket lid is also connected to the outlet of the vacuum cleaner 4 via a pipe, and the inlet of the vacuum cleaner 4 is connected to the vacuum hood 1 via a pipe. Specifically, a pipe interface 3 is provided at the end of the vacuum hood 1 away from its opening, and the pipe interface 3 is connected to the pipe. During use, the air supply device 2 and the vacuum cleaner 4 are turned on simultaneously. The air supply device 2 sends a high-speed airflow through the pipe into the air blower 11, and then blows the gas out from the air blower 11. The vacuum cleaner 4 creates a negative pressure inside the vacuum hood 1, allowing the wood chips generated by the engraving machine tool when engraving the board to be sucked into the vacuum hood 1. Then the wood chips enter the collection bucket 14 through the pipe. Excess gas in the collection bucket 14 can be discharged out through the vent 13. The filter screen in the vent 13 can filter the gas, keeping the gas entering the air clean.

[0024] The specific process is as follows: The material to be carved (such as...) Figure 4 (As indicated by the middle arrow C) is placed on the machine tool, with the air blower 11 aligned with the tool at the bottom of the engraving head, as... Figure 4 As shown, the bottom of the dust hood 1 is also positioned above the board, as... Figure 4 As shown, during the engraving process, there is a gap between the bottom edge of the opening of the dust hood 1 and the board to prevent the dust hood 1 from touching the board.

[0025] After the sheet metal is placed on the machine tool, the machine head moves from one end of the sheet metal to the other end (e.g., ...). Figure 4 As indicated by the middle arrow A, during the movement from one end to the other, the tool carves the surface of the board piece by piece. During the carving process, the resulting debris is blown up by the air blower 11 and drifts towards the dust collection hood 1 (as shown by the arrow). Figure 4 (As indicated by the middle arrow B), the air blower 11 blows all the carving debris into the dust collection hood 1, allowing the carving debris to be cleaned up quickly.

[0026] To prevent debris from flowing out from the edge of the vacuum hood 1, a funnel-shaped collection cover 12 is specially provided at the edge of the opening of the vacuum hood 1, which can increase the collection area of ​​the opening of the vacuum hood 1.

[0027] Based on the above embodiments, it should be further explained that, as Figure 4 As shown, the air blower 11 can blow up the debris and direct it toward the dust hood 1. The dust hood 1 will suck in the debris. Therefore, with the combination of the dust hood 1 sucking in the debris and the air blower 11 blowing the debris, the debris can be completely sucked into the dust hood 1.

[0028] Based on the above embodiments, further optimization can be achieved by providing a soft rubber lip at the bottom edge of the dust hood 1, allowing the bottom of the rubber lip to elastically rest on the surface of the board, thereby sealing the gap between the dust hood 1 and the board.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
