Shown in Figure 5 is the automatic powder feeding device of unidirectional powder feeding, this device comprises epitrochoidal chamber 1, hopper 2, quantitative feed mechanism 6, driver train, feeding roller 10, actuating unit 15 parts such as grade, hopper 2 is positioned at epitrochoidal chamber 1 in-to-in one side, its inlet point is positioned at the sidepiece of epitrochoidal chamber 1, quantitative feed mechanism 6 is positioned at the below of hopper 2, this mechanism is by waiting fraction quantitative slot 7 and housing 5 to form, housing maintains static, its inlet point is corresponding with the discharging opening of hopper 2, be movably arranged in the housing 5 Deng fraction quantitative slot 7, the axle of this quantitative slot links to each other with the exterior driver train of epitrochoidal chamber rear wall, feeding roller 10 a little higher than driving surface 14 certain distances, the axle of this feeding roller is connected on the actuating unit 15 that collision block is housed.
Among above-mentioned two embodiment, epitrochoidal chamber, hopper, quantitative feed mechanism, driver train, feeding roller and actuating unit are essential member of the present utility model, but powder-laying funnel, mixer automatically controlled preheating mechanism etc. can be set up as required.
The mechanism that drives the driving of quantitative feed device is a prior art, and the mode of its realization has multiple, as ratchet device, calibration rotating disk or the rotation of driven by motor calibration etc.When adopting driven by motor calibration rotation mode, the quantitative feed device is by the rotation of motor-driven calibration, and its rotation is coordinated mutually with the feeding roller sway.Need not be provided with collision block on the engine installation this moment.
Quick shaping process needs raw MAT'L is carried out preheating usually, and when adopting the utility model, also other position in hopper and epitrochoidal chamber is provided with a plurality of preheating mechanisms and temperature control mechanism as required.Usually, the raw MAT'L preheating temperature in the charging basket can not be too high, so as not to the raw MAT'L bonding, influence shop powder.But the heating-up temperature of epitrochoidal chamber can be higher, as long as be lower than raw-material fusion temperature slightly.
Be example with ratchet device as the unidirectional automatic powder feeding system of driver train and belt stirrer below, principle of work of the present utility model is described.Preheating mechanism carries out preheating to raw MAT'L in the charging basket and epitrochoidal chamber, and controls its temperature to satisfy laser sintered requirement by temperature control mechanism.Actuating unit can drive feeding roller and rotate also sway on work top simultaneously.When feeding roller moved to the end position of a side, active ratchet on the collision block bump ratchet on the actuating unit drove ratchet and rotates, and the fraction quantitative slot that waits that ratchet drives automatic feed mechanism again rotates lattice.Simultaneously, spacing ratchet moves lattice, prevents the ratchet counter-rotating.Collision block is the ram drive bar simultaneously, make the certain angle of drive spindle swing, the work of drive mixer, it is smooth and easy to guarantee that powder falls, at this moment the powder in the hopper is arranged in the lattice of quantitative slot of the inlet point of quantitative slot housing because of deadweight falls into, and the powder that is arranged in the quantitative slot lattice of housing discharging opening falls into powder-laying funnel because of deadweight.Subsequently, actuating unit drives powder-laying roller and oppositely moves, collision block counter motion simultaneously, and ratchet oppositely moves lattice and gets back to original position under the support of driving ratchet, action of reset spring.Simultaneously, original position is arrived in the backswing under the effect of backspring of the drive spindle of powder blender, and stirs the powder in the charging basket.Simultaneously, powder-laying funnel is in the process that moves with feeding roller, and powder wherein constantly drops on the work top from its elongated shape outlet, and feeding roller pushes away flat and compacting with powder, for laser sintered use.After this layer sintering finished, epitrochoidal chamber descends one and spreads powder layer thickness, carries out feeding next time, stone again, and so circulation drives the feeding roller side-to-side movement, to realize quantitative feed and stone, the separation type about unnecessary powder can fall into by spillway is overflowed the powder handling tube.
