Belt wheel；Two pieces guide pillar is affixed on power spreading device seat by the first guide pillar fixed seat and the second guide pillar fixed seat, and sliding block leads to
The movement for crossing belt is moved freely on two pieces guide pillar；Synchronous pulley is arranged on the bearing block with bearing by follower shaft
On, bearing block is fixed on power spreading device seat；First jet and second nozzle are separately fixed at first jet fixed support and
On two nozzle fixed supports, and it is fixed on by connector on sliding block；It is soft that first jet and second nozzle are connected to first
Pipe and the second flexible pipe, scraper are fixed on power spreading device seat.
Preferably, described first jet and second nozzle are respectively placed in the both sides of scraper.
Preferably, described first jet and second nozzle are connected to the confession powder of outside by the first flexible pipe and the second flexible pipe
Equipment, and its control end is connected with software control system.
The present invention compared with prior art, with advantages below：
1. can realize it is two-way send powdering, improve powdering efficiency, ensure that powdering quality, it is to avoid mixed in recovery powder
Enter the impurity such as the oxide particle that is produced during 3D printing.
Nozzle can be carried out random position by 2 by software control system in the top of moulding cylinder, carried out quantitative powder feeding, protected
Powdering quality is demonstrate,proved, powder using efficiency is greatly improved.
Apparatus of the present invention can be connected with outside powder feeding for powder equipment, and selective laser will be caused to be melted and molded device structure more
Plus it is simplified, compact, operation more facilitates.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, a kind of 3D printing dedicated removable spraying type powder sending and laying device, including motor 1, motor 1 is under
The electric machine support 2 of side is fixed on power spreading device seat 6, and motor 1 is connected with active synchronization belt wheel 3；Two pieces guide pillar 5 is led by first
The guide pillar fixed seat 11 of post fixed seat 4 and second is affixed on power spreading device seat 6, and sliding block 10 is by the movement of belt 15 two
Moved freely on part guide pillar 5；Synchronous pulley 13 is arranged on the bearing block 12 with bearing by follower shaft 14, bearing block 12
It is fixed on power spreading device seat 6；First jet 8 and second nozzle 16 are separately fixed at the spray of first jet fixed support 9 and second
On mouth fixed support 18, and it is fixed on by connector 19 on sliding block 10；First jet 8 and second nozzle 16 are connected to
One flexible pipe 17 and the second flexible pipe, scraper 7 are fixed on power spreading device seat 6.
The present invention improvement and operation principle be：Described first jet 8 and second nozzle 16 is respectively placed in the two of scraper 7
Side, described first jet 8 and second nozzle 16 is connected to the confession powder equipment of outside by the first flexible pipe 17 and the second flexible pipe 20,
And its control end is connected with software control system, when carrying out powdering work, sliding block 10 is returned into origin position first, will
First jet 8 and second nozzle 16 are moved to the side of moulding cylinder；When powder feeding to be started, software control system sends powder feeding life
Make and being operated to outside for powder equipment and motor 1, motor 1 works, sliding block 10 drives first jet 8 and second nozzle 16 to move
To the opposite side of moulding cylinder, during sliding block 10 is moved to moulding cylinder opposite side, first jet 8, which is opened, carries out powder feeding, and
Second nozzle 16 closes powder feeding, when sliding block 10 reaches moulding cylinder opposite side, simultaneously closes off first jet 8, then proceeds by
Powdering works.
When current powdering layer carries out laser printing, software control system sends powder feeding order and supplies powder equipment and electricity to outside
Machine 1 is operated, and motor 1 works, and sliding block drives first jet 8 and second nozzle 16 from moulding cylinder when front side returns to shaping
The opposite side of cylinder, during sliding block 10 returns to moulding cylinder opposite side, second nozzle 16, which is opened, carries out powder feeding, and nozzle 8
Powder feeding is closed, when sliding block 10 reaches moulding cylinder opposite side, second nozzle 16 is simultaneously closed off, current powdering layer laser is then waited
Printing terminates, and at the end of the layer laser printing of current powdering, proceeds by powdering work.So in powder sending and laying device of the present invention
During one moves back and forth, you can realize two-way powder laying.
When the part of printing is in " pyramid " shape, more up print, the current layer profile of part is smaller, print area
It is smaller, at this point it is possible to which according to parts profile position, the starting of adjustment sliding block 10 and final position, and apparatus of the present invention are relative
Starting and final position in moulding cylinder, have reached the powdering time that reduces, the purpose for reducing powder sending quantity, improving powder using efficiency.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
