[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0025] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0026] The dust collection device in this embodiment is as follows: Figure 1 As shown, it can be installed on a CNC engraving machine to collect the debris and dust generated during the engraving process. The main structure of the CNC engraving machine described in this example is largely the same as that of existing CNC engraving machines, mainly including a worktable and an engraving motor 20. A sliding frame is provided on the worktable, and a crossbeam is provided at the upper end of the sliding frame. The motor 20 can be slidably connected to the crossbeam through a slide block 10, that is to say, the motor 20 can move horizontally relative to the crossbeam.

[0027] like Figure 1 As shown, the dust collection device of this embodiment mainly includes: a mounting base 1, a dust collection hood 2, an adjusting cylinder 3, and a vacuum cleaner (not shown). The mounting base 1 is connected to the slide 10 and supports the dust collection hood 2, the vacuum cleaner, and the adjusting cylinder 3, allowing the entire device to move with the motor 20 to collect the debris and dust generated by the motor 20 in a timely manner. The cylinder body 31 of the adjusting cylinder 3 is fixedly connected to the mounting base 1, and the dust collection hood 2 is fixedly connected to its piston rod. The adjusting cylinder 3 can raise and lower the dust collection hood 2, thereby adjusting the distance between the dust collection hood 2 and the surface of the workpiece to be processed. The dust collection hood 2 is connected to the vacuum cleaner via a flexible hose (not shown), and the vacuum cleaner includes a dust collection box.

[0028] With the above structure, the dust collection device of this embodiment is installed next to the motor 20 of the CNC engraving machine, which can collect the debris and dust generated by the motor 20 in a timely manner. By adjusting the extension and retraction of the piston rod of the adjusting cylinder 3, the distance between the dust collection hood 2 and the workpiece surface can be adjusted, so that the distance between the dust collection hood 2 suction port and the workpiece is minimized, which can greatly collect debris and dust into the dust collection box. Since the piston rod stroke of the adjusting cylinder 3 is adjustable, this dust collection device can be adapted to products of different specifications and has strong versatility.

[0029] Combination Figure 1 and Figure 2 As shown, the regulating cylinder 3 in this embodiment is a double piston rod cylinder. The cylinder includes an upper piston rod 32 located at the upper end of the cylinder body 31 and a lower piston rod 33 located at the lower end of the cylinder body 31. The dust collection hood 2 is connected to the lower piston rod 33 of the cylinder.

[0030] Better, combined Figure 2 and Figure 3As shown, the upper piston rod 32 of the regulating cylinder 3 is also provided with a stroke adjusting plate 4, which is detachably connected to the upper piston rod 32. Specifically, in this embodiment, the stroke adjusting plate 4 is provided with two through holes for the upper piston rod 32 to pass through. The opposite sides of the two through holes are respectively penetrated, so that the two ends of the stroke adjusting plate 4 respectively form grooves. Threaded holes are provided on the two side walls of the grooves. By screwing bolts into the threaded holes, the two side walls of the grooves can be brought together, thereby fixing the stroke adjusting plate 4 on the upper piston rod 32.

[0031] By adopting the above solution, the height of the dust collection hood 2 can be controlled and fixed at a precise position to prevent the dust collection hood 2 from descending excessively.

[0032] Combination Figure 1 , Figure 4 and Figure 5 As shown, the dust collection hood 2 of this embodiment includes a first part 21 and a second part 22 connected to each other, which are disposed opposite to each other on both sides of the motor 20. Each of the first part 21 and the second part 22 has an inner cavity, and each inner cavity has multiple suction holes 211 at its bottom, evenly distributed along the bottom of the inner cavity. Each inner cavity also has a dust outlet 212, and two dust outlets 212 are connected to a vacuum cleaner via a flexible hose. Specifically, the dust collection hood 2 can be welded from stainless steel. Except for the suction holes 211 and dust outlets 212, the remaining parts of the first part 21 and the second part 22 are largely enclosed on all four sides, which helps improve the dust collection effect. Each dust outlet 212 is connected to a flexible hose interface 23 for easy hose installation. Using the above scheme, the dust collection hood 2 of this embodiment has a large coverage area, which is beneficial for the simultaneous collection of debris and dust on both sides of the motor 20 during the engraving process, improving collection efficiency.

[0033] Furthermore, combined Figure 1 and Figure 2 As shown, the mounting base 1 in this embodiment includes two mounting plates 11, which are located on both sides of the motor 20 and are respectively connected to the slide 10. The adjusting cylinder 3 is fixed on one of the mounting plates 11. Each mounting plate 11 is connected to a hose fixing ring 5, and two hoses are respectively inserted into the two hose fixing rings 5, which is beneficial for the storage of the hoses.

[0034] In this embodiment, both the regulating cylinder 3 and the vacuum cleaner are electrically connected to the automatic control system of the CNC engraving machine.

[0035] Before use, personnel adjust and fix the position of the stroke adjustment plate 4 according to the required distance between the dust collection hood 2 and the surface of the workpiece. During use, when the motor 20 starts engraving, it sends a signal to the automatic control system, and the adjusting cylinder 3 starts to move, driving the dust collection hood 2 downwards, and the vacuum cleaner starts to operate. After engraving is completed, the upper and lower piston rods of the adjusting cylinder 3 retract completely, and the dust collection hood 2 moves upwards together, providing space and convenience for the motor 20 to change tools.

[0036] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
