Embodiment 1
[0042] Such as figure 2 As shown, in the anti-burning and dust removal system in this embodiment, the dust removal device 1 may include, for example, a gate valve 1-4, an exhaust air duct 1-5, a collection cover 1-1, a sealing cover 1-2, a control execution Elements 1-3.
[0043] The exhaust air duct 1-5 is located on both sides of the laser cutting machine body 5, its inlet end is the air exhaust port, the gate valve 1-4 is provided, and the outlet end is connected to the smoke purification device.
[0044] The collection cover 1-1 can be, for example, hopper-shaped, and its lower end is connected with one end of the sealing cover 1-2, and the other end of the sealing cover 1-2 is sealed and connected with the laser cutting machine body 5, and is placed on the laser cutting machine worktable. A plurality of dust removal areas are formed; each dust removal area is provided with a collection cover and two gate valves, and the gate valves are located under the plate to be cut....
Embodiment 2
[0062] Based on the anti-burning and dust removal system in the foregoing embodiments, this embodiment provides a dust removal method for a laser cutting machine, the method comprising:
[0063] During the laser cutting process, at least one dust removal area corresponding to the light output area of the laser cutting head is opened to collect the waste gas and dust generated during the cutting of the laser cutting head, and enter the smoke purification device through a micro-negative pressure dust removal environment for purification;
[0064] The micro negative pressure dust removal environment is a semi-enclosed space formed by the bed and the dust removal device.
[0065] Wherein, during the laser cutting process, at least one dust removal area corresponding to the light emitting area of the laser cutting head is opened, including:
[0066] When the plate to be processed is on the workbench, the control system of the laser cutting machine combines with the typesetting ...
Embodiment 3
[0073] Such as Figure 5 as shown, Figure 5 It is a schematic diagram of the distribution of the dust removal area corresponding to the coordinate position, which includes several independent partitions, for example, it can be marked as: A1, A2, A3, A4, A5, A6, and each independent partition is a dust removal area. And when the cutting path continues in more than two above-mentioned independent partitions, it is a cross-region partition. No matter in any form or kind of combination in the coordinate position, it is collectively referred to as cross-domain partitioning, which falls within the scope of the present invention.
[0074] As mentioned above, depending on the dust removal area where the cutting path is located, there are different situations as follows:
[0075] The cutting path of the laser cutting head is located in a single dust removal area, for example, either in the A1 partition or in the A2 partition, when the laser cutting head moves from one dust removal a...
