[0031] Combine the following Figure 1-Figure 4 The utility model describes a dust removal device for a laser cutting machine.

[0032] In view of the problem of large amount of smoke and dust when the laser cutting device is working in the traditional technology, an embodiment of the utility model provides a dust removal device for a laser cutting machine, including a dust removal pipeline 1, a centrifugal fan and a vacuum generator 2.

[0033] The dust removal duct 1 includes a main duct 11 and a branch duct 12. The branch duct 12 is connected to the main duct 11. A plurality of dust removal ports 13 are provided on the branch duct 12. Each dust removal port 13 is used to correspond to a laser cutting station in sequence. A centrifugal fan is provided on the main duct 11. The laser cutting machine 3 will move to cut objects. During the movement of the laser cutting machine 3, a plurality of laser cutting stations will be formed. A large amount of smoke will be generated at each laser cutting station and its surroundings. By setting the dust removal port 13 corresponding to the laser cutting station, the centrifugal fan on the main duct 11 can suck the smoke into the branch duct 12 through the dust removal port 13 when it is turned on, and discharge it through the main duct 11, so as to effectively clean the smoke. Furthermore, affected by the power of the centrifugal fan and the length of the branch pipe 12, the suction force is weaker in an area farther away from the centrifugal fan. Therefore, in the technical solution provided by the utility model, the branch pipe 12 is also provided with a vacuum generator 2, which is used to form a vacuum to form a huge pressure difference inside and outside the branch pipe 12, so as to absorb the smoke and dust near each dust removal port 13, thereby more significantly improving the dust removal effect.

[0034] It should be noted that a vacuum generator 2 may be provided for multiple dust removal ports 13, or a vacuum generator 2 may be provided for one dust removal port 13. In an embodiment provided by the utility model, a vacuum generator 2 is provided at each dust removal port 13, and the vacuum generator 2 corresponds to the dust removal port 13, so that the smoke and dust of each laser cutting station can be well adsorbed.

[0035] The vacuum generator 2 can be directly arranged in the branch pipe 12 or arranged outside the branch pipe 12 and then connected to the branch pipe 12. In an optional embodiment, please refer to Figure 1-Figure 4 The dust removal port 13 is provided on one side of the branch pipe 12, and an air port 14 is provided on the other side of the branch pipe 12, and the air port 14 is arranged opposite to the dust removal port 13. The vacuum generator 2 is provided on the outer wall of the branch pipe 12, and the vacuum port of the vacuum generator 2 is connected to the air port 14. It should be noted that the air port 14 corresponds to the dust removal port 13, and the vacuum generator 2 can vertically generate suction to the air near the dust removal port 13, thereby increasing the suction force and improving the dust removal effect.

[0036] Specifically, the vacuum generator 2 includes a vacuum member 21 and an air guide hood 22. The vacuum member 21 is arranged on the air guide hood 22, and the air guide hood 22 is covered at the air outlet 14. The air guide hood 22 can make the suction force more concentrated, thereby improving the dust removal effect. In an optional embodiment, the cross-sectional area of ​​the air guide hood 22 gradually decreases from the direction close to the air outlet 14 to the direction away from the air outlet 14. In this way, the air guide hood 22 forms a conical structure, and the cross-sectional area gradually expands, which can improve the suction force. In a specific embodiment, the air guide hood 22 is formed in a trumpet shape.

[0037] Furthermore, the vacuum generator 2 includes a main vacuum pipe 23 and a plurality of auxiliary vacuum pipes 24 connected to the main vacuum pipe 23, and each auxiliary vacuum pipe 24 is connected to the air duct 22. In order to facilitate the installation of the vacuum component 21, a bracket is provided on the air duct 22, and the bracket can conveniently install the vacuum component 21. Furthermore, in order to facilitate the connection between the vacuum component 21 and the air duct 22, a quick-connect plug 25 is provided on one side of the air duct 22, and the vacuum generator 2 is plugged into the quick-connect plug 25 to communicate with the air duct 22. The quick-connect plug 25 is provided with a plurality of sockets, and the auxiliary vacuum pipes 24 can be plugged into the sockets to complete the connection with the air duct 22.

[0038] When performing laser cutting, it is possible that some dust removal ports 13 do not need to work. Therefore, in the technical solution provided by the utility model, a movable door 26 is also provided at the dust removal port 13, and the movable door 26 is used to open or close the dust removal port 13. Specifically, the movable door 26 includes a first grid door 261, a second grid door 262 and a drive motor 263 arranged side by side. The first grid door 261 is fixed to the dust removal port 13, and the second grid door 262 is driven to move by the drive motor 263. The second grid door 262 can close the dust removal port 13 in the initial state. When the drive motor 263 drives the second grid door 262 to move, the grid of the second grid door 262 no longer blocks the opening in the first grid door 261, and the dust removal port 13 can be opened.

[0039] Please note that Figure 1 , the branch pipes 12 can be arranged in multiple numbers, and a laser cutting machine 3 can be placed between every two branch pipes 12 for cutting work. In an optional embodiment, in order to ensure that the suction force of the centrifugal fan is sufficient to suck out the smoke and dust, the dust removal pipe 1 includes two branch pipes 12, and the two branch pipes 12 are arranged at both ends of the main pipe 11, and the main pipe 11 and the branch pipes 12 are arranged vertically. The laser cutting machine 3 is arranged between the two branch pipes 12 and cuts along the extension direction of the branch pipes 12, so that the laser cutting can be performed while the dust is sucked, thereby improving the working effect.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
