Detailed Description
Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model.
The utility model is described in further detail below with reference to fig. 1-3.
The embodiment of the utility model discloses a dust removing device for oversized-format laser selective melting equipment. Referring to fig. 1-3, a dust removing device for an oversized-format laser selective melting device comprises a main frame 1, a plurality of cross beams 11 for uniformly dividing the main frame 1 into a plurality of dust removing areas are arranged in the main frame 1, in this embodiment, the number of the dust removing areas is three in an array arrangement manner, in other embodiments, the number of the dust removing areas is determined according to the size of a scanning format, the main frame 1 can be driven to move on the scanning format, and an electric pushing bar is arranged on the laser selective melting device and is used for pushing the main frame 1 to move, and meanwhile, the moving speed of the main frame 1 is matched with the laser printing speed.
Two crossbeams 11 opposite sides of every dust removal region are equipped with respectively and blow wind gap 12 and dust absorption mouth 13, the both sides of main frame 1 are equipped with air intake 15 and air outlet 16 respectively, be equipped with in the skeleton of every crossbeam 11 and main frame 1 and be used for cleaing away the dust removal passageway 14 of inhaled dust, the dust enters into in the dust removal passageway 14 through dust absorption mouth 13, air intake 15 and the equipment in the blast apparatus intercommunication, the blast apparatus blows out 1 through air intake 15 to the dust removal passageway 14 in, the wind that produces blows out 1 through blow wind gap 12, the dust that produces when printing blows to dust absorption mouth 13 direction, make the dust enter into in the dust removal passageway 14 from dust absorption mouth 13, can clear away the dust that produces in every dust removal region, can remain partial wind power in the dust removal passageway 14 simultaneously, can blow the dust of dust accumulation in the dust removal passageway 14 in the crossbeam 11 to the opposite side of main frame 1, and blow out main frame 1 through air outlet 16, can avoid the dust accumulation in the dust removal passageway 14 too much influences the dust absorption effect.
Meanwhile, in order to avoid the use of blowing and dust collection of the cross beam 11, a partition board 111 for separating the blowing areas and the dust collection areas of the two dust collection areas is arranged in the cross beam 11 along the length direction of the cross beam 11, and the partition board 111 divides one cross beam 11 into two parts, so that the mutual influence of blowing and dust collection can be avoided.
In the use, firstly move array frame-type dust collector to equipment one side, wait that this regional scanning is accomplished the back, remove the device to the another side to let the region that is sheltered from by dust collector, can be scanned, because crossbeam 11 can shelter from partial scanning breadth, the width in dust removal region is greater than the width of crossbeam 11 far away, can be as far as less crossbeam 11 shelter from the area of scanning breadth, can reduce the travel distance of main frame 1.
