Rate.
Figure 10 is the few examples of the engraved structure of guiding device in the utility model, and with reference to Figure 10, a figure in Figure 10 is
The schematic cross-section of strip groove 273,273 ' in above-mentioned first, second embodiment, the strip groove groove width are gradually reduced from up to down,
The air-flow or dust particles that can effectively prevent 27 lower section of the first guiding device flow up.Similarly, the b figure in Figure 10 is above-mentioned
The schematic cross-section of through-hole 274,274 ', the aperture of the through-hole 274 are gradually reduced from up to down in first, second embodiment, together
The air-flow of 27 lower section of the first guiding device can be effectively prevented in sample or dust particles flow up.
3rd embodiment:
Figure 11 is the cross-sectional view of dust-extraction unit one embodiment of the utility model, with reference to Fig. 1,11, dust excluding hood 2
Inside further includes inlet chamber 201 and outlet chamber 203, and inlet chamber 201 is connected to the side of dedusting chamber 202, outlet chamber 203 and dedusting
The other side of chamber 202 is connected to, so that inlet chamber 201, dedusting chamber 202 and outlet chamber 203 are sequentially communicated, dust excluding hood 2 is in inlet chamber
The first air inlet 21 for air inlet is offered at 201, and the gas outlet 23 for outlet, air-flow are offered at outlet chamber 203
Enter inlet chamber 201 by the first air inlet 21, and flow through dedusting chamber 202 and take away the dust generated at cutting mouth 22, then flows
Enter outlet chamber 203 and flow out dust excluding hood 2 from gas outlet 23, reaches dustproof function.In conjunction with above-mentioned it is found that being arranged in dedusting chamber 202
The first guiding device 27 realize the subregion guide functions of 202 interior air-flow of dedusting chamber, so as to corresponding logical from air inlet 21
The air-flow for entering different wind speed reduces the high-speed flow of 22 lower section of cutting mouth to cutting mouth 22 under the premise of realizing effective dedusting
The influence of the pole piece at place is effectively prevented from pole piece generation and generates and acutely significantly shakes and defocus, to guarantee that laser stabilization is cut
It cuts, to improve cut quality and cutting efficiency.
Dust cover 2 is also provided with the second air inlet 24 on outlet chamber 203, plays the role of release, when gas outlet 23 is negative
When pressing larger, portion gas enters 23 outlet chamber 203 of gas outlet from the second air inlet 24 and realizes release, reduces dedusting chamber
Wind speed in 202 reduces air-flow and shakes defocus influence caused by pole piece, to guarantee that laser stablizes cutting.
Second air inlet 24 is provided on the side wall of dust excluding hood 2, and edge is inclined from dedusting chamber 202 to the direction of gas outlet 23
Tiltedly, the area that can expand the second air inlet 24 and 203 connectivity part of outlet chamber, facilitates abundant air inlet release.In the present embodiment, remove
Second air inlet 24 is provided on dust hood 2, when it is implemented, can also set on the side wall of the corresponding outlet chamber 203 of dust excluding hood 2
Multiple second air inlets 24 are set to reach above-mentioned effect.
Outlet chamber 203 is gradually reduced from dedusting chamber 202 to the direction of gas outlet 23, closing-in structure is formed, so that in outlet
When being evacuated at mouth 23, it is possible to increase flow velocity reduces pressure.
Dust excluding hood 2 is straight-through structure, and inlet chamber 201, dedusting chamber 202 and outlet chamber 203 are from one end of dust excluding hood 2 to another
One end is sequentially communicated, therefore airflow channel is put-through channel, helps to improve efficiency of dust collection.
Based on above-mentioned dust excluding hood 2, the draft hood 3 of dust-extraction unit is connected to the gas outlet 23 of dust excluding hood 2, and with pumping gas source
(not shown go out) connection, when work, pumping gas source (not shown go out) is evacuated draft hood 3, so as to by the sky inside dust excluding hood 2
Gas is extracted out from gas outlet 23, while taking dust out of dust excluding hood 2, realizes the purpose being dusted in time in laser cutting.
Common air knife may be selected as air inlet to obtain larger air inlet wind speed in the also settable inlet duct 1 of dust-extraction unit
Device, the inlet duct 1 are arranged at the first air inlet 21 and to supplying gas inside dust excluding hood 2, and formation is evacuated while supplying gas
Dust-cleaning scheme, help to improve efficiency of dust collection.
Consider that inlet duct 1 is supplied gas the pole piece that will affect at cutting mouth 22, generates pole piece under airflow function acutely
Significantly shake, the bottom at corresponding first air inlet 21 of inlet duct 1 is arranged, thus the air-flow that inlet duct 1 is supplied gas
It is most of to be blown to the bottom of cutting mouth 22, influence of the air-flow to pole piece of supplying gas can be reduced, and can blow away and be deposited in dedusting chamber
The large dust particle of 202 lower parts, to improve efficiency of dust collection.
To obtain suitable air inlet wind speed, it may also set up multiple inlet ducts 1 at the first air inlet 21 and supply gas, it can be right
Lower wind speed of supplying gas is arranged in inlet duct 1 corresponding with 22 height of cutting mouth, avoids air-flow excessive and keeps pole piece generation excessive
Shake.Relatively, relative altitude is located at the settable relatively high wind speed of supplying gas of inlet duct 1 of 22 lower section of cutting mouth, from
And the large dust particle for being deposited in 202 lower part of dedusting chamber is effectively removed, to improve efficiency of dust collection.
Fourth embodiment:
Figure 12 is the cross-sectional view of the 4th embodiment of dust-extraction unit of the utility model, and with reference to Figure 12, the present embodiment is removed
