The dust removing fan 150 is connected with the air draft dust removing pipeline 110 and is used for exhausting smoke dust. The dust removing fan 150 may be disposed on the laser cutting machine 200, or may be disposed at a position actually required in other machining processes.
Currently, the system for removing the smoke dust in the large-format laser cutting machine 200 with a large area is to extract the generated smoke dust by the dust removing fan 150. The method has the advantages that the whole laser cutting machine tool 200 is directly ventilated, ventilation is not accurate, firstly, the generated ventilation suction force is weak, the ventilation effect is poor, smoke and dust are easy to diffuse in a workshop, precise parts are polluted, and the body health of workers is damaged; and secondly, the smokeless area is drafted simultaneously, so that the production cost is improved.

And further, the smoke sensing subsystem 130 is arranged to extract smoke which is diffused to other positions near the laser cutting machine on the basis of the above. The feedback subsystem and the smoke sensing subsystem 130 are matched with each other and complement each other, time two-stage accurate air draft is carried out, and the smoke is accurately and completely extracted to the greatest extent.
Therefore, this convulsions dust pelletizing system 100 convulsions is accurate, and the convulsions suction that corresponds smoke and dust department and produce is strong, and exhaust effect is good, and the smoke and dust is difficult to fill in the workshop, and the protection precision part and staff's is healthy, reduction in production cost.

The photoelectric smoke sensor 131 has different smoke sensing thresholds according to different models, and the model can be selected according to actual requirements.
In this embodiment, the photoelectric smoke sensor 131 is suitable for the case where the smoke particles are larger than other smoke sensors 131, such as the ion smoke sensor 131, and the photoelectric smoke sensor 131 is suitable for the case where the smoke particles generated by the laser cutting machine are larger. In addition, different choices of sensing threshold values can be realized by selecting the photoelectric smoke sensors 131 with different models, so that the situation that whether smoke exists or not can be detected, the size of the smoke can also be detected, more accurate smoke positioning can be realized, and the size of opening of the air door 111 of the air draft and dust removal pipeline 110 of the dust removal pipeline can be controlled.

When the position feedback subsystem 120 does not detect that the laser cutting machine travels to other positions, or the smoke sensing system does not detect smoke, the control subsystem 140 closes the damper 111 of the air draft dust removal pipeline 110 by controlling the air cylinder electromagnetic valve 115, so that the damper 111 of the air draft dust removal pipeline 110 is opened and closed.
As shown in FIG. 3, the ID duct 110 includes a first duct 112 and a second duct 113.

s500: and starting the dust removal fan to remove smoke dust.
When the laser cutting machine tool 200 is used for performing laser cutting operation, when the laser cutting machine tool is used for cutting workpieces, the auxiliary gas and the laser beam are coaxially sprayed, so that the heat dissipation, combustion supporting, molten stain blowing and cutting surface quality improvement are realized, a large amount of smoke is generated, the smoke permeates into the working space of the whole laser cutting machine tool 200, the precision part cutting head is polluted, the service life and the stability of the precision part cutting head are influenced, the working environment is seriously polluted, and the physical health of workers is harmed. At present, the method for removing the smoke dust in the large-breadth laser cutting machine 200 with a large area is to extract the generated smoke dust by the dust removing fan 150.

And then the air draft dust removal pipeline 110 corresponding to the position of the laser cutting machine is opened through S200, and first-stage accurate positioning air draft is carried out. In the processing process, the smoke dust can be continuously diffused to the periphery and can be gradually diffused to other positions near the position of the laser cutting machine. Next, the position of the smoke is determined through step S200, where the determined position may also include the position determined in step S100, and also include the smoke permeating to other positions near the laser cutting machine, and if there is the smoke, the position is included therein, and then the exhaust dust removal pipe 110 corresponding to the position of the smoke is opened to perform the second-stage precise positioning exhaust. By the method, the smoke dust at the position of the laser cutting machine or the smoke dust at other positions after dispersion can be accurately positioned, and then the air draft dust removal pipeline 110 corresponding to the smoke dust is opened. It should be noted that, in the method, steps S100 and S200 are set first, and not only steps S300 and S400 are set directly, so that the positioning of steps S100 and S200 is more accurate, and at the same time, the position is also the most main concentration position of the smoke dust, which can ensure that most of the smoke dust is extracted more accurately. Further, the arrangement of S300 and S400 is such that the smoke diffusing to other positions near the laser cutting machine can be extracted. The S100 and the S200 are matched with each other, the S300 and the S400 are mutually complemented, two-stage accurate air draft is carried out, and the smoke is furthest ensured to be drawn away. The method has the advantages of accurate air draft, strong air draft suction force generated at the corresponding smoke dust position, good air draft effect, difficult diffusion of the smoke dust in a workshop, protection of the health of precise parts and workers and reduction of the production cost.

The step of S300 determining the position of the smoke generated by laser cutting specifically comprises the following steps: detecting whether smoke exists, wherein smoke generates a smoke feedback signal if smoke exists; specifically, whether smoke exists is detected, wherein the smoke size is detected when the smoke exists, and a smoke feedback signal is generated. The generated smoke feedback signal is an electrical signal that may be fed back to the control subsystem 140 of the laser cutting machine 200.
The step of opening the air draft dust removal pipeline 110 corresponding to the position of the smoke dust is specifically as follows: according to the smoke feedback signal, opening an air door of the air draft dust removal pipeline corresponding to the position of the smoke corresponding to the size of the smoke; the size of the opening damper 111 corresponds to the size of the smoke. According to the size of smoke and dust feedback signal, corresponding the smoke and dust, open air door 111's size, the amount of air suction matches with the smoke and dust volume is accurate, and more accurate individual convulsions are removed the smoke and dust effectively. Here, the control subsystem 140 of the laser cutting machine 200 receives the feedback smoke feedback signal and controls the opening of the damper 111 according to the smoke feedback signal.
In addition, the step of S300 determining the position of the smoke generated by laser cutting may also specifically be: detecting whether smoke exists, wherein the smoke exists, and detecting which of the two sides of the laser cutting machine tool the smoke exists.
S400, the step of opening the air draft dust removal pipeline corresponding to the position of the smoke dust can also be specifically as follows:

s420: and closing an air draft dust removal pipeline which is not corresponding to the position of the smoke dust in one side of the laser cutting machine tool where the smoke dust is positioned and an air draft dust removal pipeline on the other side of the laser cutting machine tool.
When cutting, for a large-format laser cutting machine 200, there may be a case where the cutting position is closer to one side of the laser cutting machine 200 (the cutting side of the laser cutting machine 200) and is far from the other side. Most of the smoke generated by cutting at this time is probably concentrated on the cutting side of the laser cutting machine tool 200, only the air draft dust removal pipeline 110 corresponding to the position of the smoke on the cutting side of the laser cutting machine tool 200 is opened, other air draft dust removal pipelines 110 corresponding to the smoke are not arranged on the cutting side of the laser cutting machine tool 200, and all the air draft dust removal pipelines 110 on the other side of the laser cutting machine tool 200 are closed, so that more concentrated air draft is achieved, the air draft sealing performance is improved, the unnecessary power consumption of the dust removal fan 150 is reduced, and the production cost is reduced.
