Abstract
A kind of powder recovering device of 3DP color three-dimensional printer, comprise the Powder Recovery groove be connected side by side with forming tank, notch place is provided with and subtracts dirt net, subtract below dirt net is that powder turns fan, powder turns the control of fan by stepper motor, and powder turns fan both sides arc smoothers plate, and what be connected with smoothers plate is the recovery port reclaiming powder, be Powder Recovery case immediately below recovery port, the powder of recovery can recycle.This device is applicable on the shaped device of various 3DP technique, and powder turns fan and arc smoothers plate can make to play during Powder Recovery well to subtract dirt dust-proof effect, and Powder Recovery speed is fast, and powder can not be caused to block recovery approach.
Description
Technical field:
The invention belongs to 3DP color three-dimensional printer field, be specifically related to the powder recovering device field of 3DP color three-dimensional printer.
Background technology:
Rapid shaping technique realizes the method for Computerized three-dimensional solid figure to physical entity, and it is on the basis based on Modern CAD technique, Computer Control Technology, elaborate servo actuation techniques, materialogy etc., can make the object that various shape is very complicated.The technique that rapid shaping technique is relatively commonly used has photocuring, selective laser sintering, fuse to deposit to make, laminated solid mass makes and 3 D-printing etc., above several rapid shaping technique, front four kinds with regard to color, monochromatic article can only be made.And color three dimension printing adopts rapid shaping and droplet ejection forming technique, layer-by-layer preparation, finally can realize the technique of colour print, and the shaping speed of this technique, far away higher than photocuring, fuse deposition, laminated solid mass manufacture craft, does not need to support yet.
3DP printer reclaims powder, in the world, the Zcorp company comprising the U.S. adopts the Design of Mechanical Structure of forming tank and accumulator tank to take planar structure, reclaim powder directly to fall from recovery notch, the setting of this structure causes that dust is counter to be raised, shaping environment dust is very large, and the shower nozzle positioning control accuracy in forming room declines, and especially causes shower nozzle to block to damage shower nozzle.
Summary of the invention
Goal of the invention: the powder recovering device improving 3DP color three-dimensional printer, solves 3DP technique in prior art and causes the very large problem of shaping environment dust when Powder Recovery.
Technical scheme: a kind of powder recovering device of 3DP color three-dimensional printer, comprise: computer, recycling powder device, powder is adopted to turn fan and arc smoothers plate, powder recovering device is positioned at forming room, Powder Recovery groove is provided with side by side with forming tank in forming room, be provided with at notch place and subtract dirt net, subtract and be provided with powder immediately below dirt net and turn fan, the both sides that powder turns fan are provided with and the smoothers plate reclaiming notch and be connected, powder turns the control of fanning by the stepper motor in accumulator tank and rotates, control powder to turn fan and be in and subtract immediately below dirt net simultaneously, all the time certain spacing is kept with the smoothers plate of both sides, powder falls into Powder Recovery case along smoothers plate.Sled design is arc skateboard.
Beneficial effect:
1, arc smoothers plate makes the powder fallen naturally slide, and falls into collection box, avoids powder and directly falls into collection box, causes that powder is counter to be raised in forming room.
2, powder turns fan and Powder Recovery case and forming room is successfully isolated, and substantially increases and dust-proofly subtracts dirt effect, improve the environment of forming room.
3, Powder Recovery speed is fast, can not block powder channel.
4, extend the service life of shower nozzle, substantially reduce use cost.
5, improve the precision of the control system of machine.

Detailed description of the invention
A kind of 3DP color three-dimensional printer powder recovering device, this device comprises: computer, with shaped platform Powder Recovery groove side by side, be provided with at the notch of accumulator tank and subtract dirt net, subtract and immediately below dirt net, powder is set turns fan, powder turns the control of fanning by stepper motor and rotates, the both sides that powder turns fan are provided with arc skateboard, under control of the computer, step motor control powder turns the fan leaf that fan is mutually 120 degree, when holding state, all the time face with the notch of accumulator tank, and keep the spacing of 1mm with arc skateboard, arc smoothers plate is connected with notch, under with recovery powder duct be connected, it is Powder Recovery case immediately below powder duct.Arc skateboard and Powder Recovery pipeline are to connecting, it is Powder Recovery case immediately below Powder Recovery pipeline, powder falls along arc skateboard, fall into collection box, powder turns the control of fanning by the stepper motor in accumulator tank and rotates, control powder electric fan and keep certain spacing with the arc smoothers plate of both sides all the time, and stepper motor under control of the computer, be mutually the flabellum of 120 degree, during holding state, face with the notch of accumulator tank, and keep the distance of 1mm with smoothers plate, to stop that the recovery powder fallen is to the anti-powder spreading dirt of forming room, thus reduce the dust of forming room widely, Powder Recovery speed is fast, powder channel can not be blocked.
Take to be provided with the powder recovering device that powder turns fan and arc skateboard structure, greatly improve the environment of forming room, play and well subtract dirt effect, make Powder Recovery speed fast, Powder Recovery passage can not be blocked, improve the precision of control system, extend the service life of printhead simultaneously, lower the use cost of printer.
Fig. 1, shown in 2, Powder Recovery groove (1) is provided with side by side with forming tank in forming room, be provided with at notch place and subtract dirt net (3), subtract and be provided with powder immediately below dirt net and turn fan (2), when powder falls, first falling powder turns on fan (2), the both sides that powder turns fan (2) are provided with and the arc skateboard (5) reclaiming notch and be connected, powder falls into Powder Recovery case (7) along smoothers plate, powder turns fan (2) and rotates by the control of the stepper motor (4) in accumulator tank, under control of the computer, step motor control powder turns flabellum that fan (2) is mutually 120 degree and is in and subtracts immediately below dirt net (3), all the time the spacing of 1mm is kept with the arc smoothers plate (5) of both sides, to stop that the recovery powder fallen is to the anti-powder spreading dirt of forming room.
This device goes on the shaped device of various 3DP technique, and turn fan and arc smoothers plate owing to employing powder, powder is cushioned when recovery notch leaks down, and then by turning fan right rotation for powder, powder is poured into arc smoothers plate, powder is made naturally to be slipped to collection box, simultaneously, because powder turns the fan leaf that fan is mutually 120 degree, all the time the spacing of 1mm is kept with arc smoothers plate, anti-when well preventing powder to fall to raise, make forming room can accomplish well to subtract dirt effect.
