Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Fig. 1 is structural representation of the invention.As shown in figure 1, a kind of powder feeding formula laser 3D printing that the present invention is provided is carried
Gas formula powder feeder, including stirring motor 1, powder feeding bucket 2, agitator 3, powder disk 4, device for inhaling powdery substances 8, powder disk closed chamber 9 and electric rotating
Machine 10, wherein powder disk 4 are rotatablely arranged in powder disk closed chamber 9, and powder disk 4 is by shaft coupling with being located under powder disk closed chamber 9
The output shaft connection of the electric rotating machine 10 of side.The powder disk 4 be provided with annular groove, the powder disk closed chamber 9 provided with
The corresponding suction powder mouthful of the annular groove and powder falling mouthful, the device for inhaling powdery substances 8 and powder feeding bucket 2 are respectively arranged at the suction powder mouthful
With in powder falling mouthful, the agitator 3 is arranged in powder feeding bucket 2 and defeated with the stirring motor 1 that is arranged at outside powder feeding bucket 2
Shaft is connected.
Powder feeding bucket 2 is airtight cavity, the pyramidal structure that the lower end of the airtight cavity smoothly falls for ease of powder,
The bottom of the pyramidal structure is provided with meal outlet.The pyramidal structure of the powder feeding barrel 2 and bottom is to be detachably connected.
The powder feeding bucket 2 is further connected with power collecting bucket, the connection of the power collecting bucket and vacuum extractor and junction
Provided with the filter for preventing that the powder in the power collecting bucket is pumped, the filter is using conventional filter structure.It is described to send
Powder bucket 2 sets powder transmission channels using hermetically sealed between design, with power collecting bucket, be easy under oxygen free condition at any time to powder feeding bucket 2
Interior addition powder material.The power collecting bucket keeps oxygen-free environment in power collecting bucket, and pass through by way of first vacuumizing and being supplemented argon gas
Powder transmission channels are realized to powder feeding bucket 2 adds powder online.By setting power collecting bucket, process powder can be achieved and mends automatically
Give.
The power collecting bucket is sealed using sealing ring, and powder adds the air that will be brought into after power collecting bucket using vavuum pump when adding powder
Extract out, to prevent powder to be pumped, Special filtering device is equipped with the junction of power collecting bucket and vavuum pump.For balance power collecting bucket with
The air pressure of powder feeding bucket 2, so that powder is smoothly flowed down, treats power collecting bucket air emptying, is filled with argon gas.In the present embodiment, power collecting bucket bucket
Footpath 100mm, the high 300mm of bucket.
For ease of amount of powder in observation powder feeding bucket 2, powder feeding bucket 2 is made of lucite.In the present embodiment, powder feeding bucket 2
Bucket footpath 100mm, the high 300mm of bucket.
The lower end of the powder feeding bucket 2 is connected by powder falling block 5 with the powder feeding mouthful in the powder disk closed chamber 9, the suction powder
Device 8 is connected by inhaling powder agglomates 6 with the suction powder mouthful in the powder disk closed chamber 9.
As shown in Figure 2 and Figure 3, the top of the powder falling block 5 is provided with what is be connected with the device for inhaling powdery substances 8 or powder feeding bucket 2
Shrinkage pool 53, bottom is provided with coordinates the protrusion platform 51 contacted, the pars intermedia of the powder falling block 5 with the annular groove on the powder disk 4
It is arranged with hollow space 52.
In order to avoid powder falling block 5 and inhale powder agglomates 6 to powder disk 4 cover power caused by powder disk 4 rotate bias, the powder disk
Suction powder mouthful and powder falling mouthful in closed chamber 9 are symmetrical arranged, and make powder falling block 5 and suction powder agglomates 6 symmetrical on powder disk 4 so that powder
The uniform force of disk 4, improves the stability and stationarity rotated.
Air pressure balance mouthful 7 is equipped with the powder feeding bucket 2 and powder disk closed chamber 9, two air pressure balances mouthful 7 pass through breather pipe
Connection, the breather pipe is the pressure in balance powder feeding bucket 2 with powder disk closed chamber, is fallen in order to the continuous-stable of powder.Meanwhile,
Air pressure balance breather pipe, which is also played, prevents powder feeding bucket 2 from producing Negative Pressure Difference with powder disk closed chamber and reducing the flowing or prevention of powder
The effect of powder powder falling.
The device for inhaling powdery substances 8 is starch sucking nozzle, and the effect of starch sucking nozzle is by the stable sucking-off of powder, by with inhaling having for powder agglomates 6
Effect coordinates, and the powder in the annular groove of powder disk 4 is smoothly suctioned out.
The agitator 3 is Multi section bar structure, and the agitator 3 is used for preventing powder from agglomeration occur, it is ensured that powder feeding
Stability and precision.Superfines and lazy flow powder easily occur reuniting and bridging phenomenon, it is difficult to ensure that powder uniformly connects
Continuous falls into annular groove, so conventional powder feeder can not often convey this kind of powder, the present invention is by designing agitator solution
Determine this problem, the agitator is by external stirring motor, using Multi section bar stirring structure, breaks up powder reunion situation, makes
Obtaining those lazy flow powder with smooth delivery of power, can improve the transfer efficiency of powder.
The powder disk 4 is that the depth of the annular groove on powder transfer device, powder disk 4 is the important determinant of powder sending quantity
One of, powder is fallen into annular groove by powder feeding bucket 2 under self gravitation effect, and powder is fallen into annular groove by powder feeding bucket 2,
The powder fallen is delivered to meal outlet by powder disk 4 by powder falling oral instructions under electric rotating machine 10 (precision DC motor) drive.Powder disk 4 is selected
45# Steel materials are used, surface need to carry out anti-oxidant treatment.
The shrinkage pool 53 on the top of powder falling block 5 and the meal outlet of 2 bottoms of powder feeding bucket are connected, bottom protrusion platform 51 and powder
The annular groove of disk 4 coordinates contact.The inside and outside circular arc of protrusion platform 51 matches somebody with somebody splice grafting with the inside and outside circle of annular groove of powder disk 4 respectively
Touch, play guide effect.Hollow between inside and outside circular arc, powder falls into limiting in annular groove by powder falling mouthful by powder falling block 5
Volumetric spaces.The structure for inhaling powder agglomates 6 is similar to the structure of powder falling block 5.
The present invention has low powder feeding rate, high powder pushing precision and stability；Single metal dust or various powders can be carried out
Blending transportation；Longer-distance conveying can be carried out；The advantages such as the uninterrupted forming of powder supply process.
Embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the present invention.It is all in the present invention
Spirit and principle within any modification, equivalent substitution and improvements, the extension made etc., be all contained in protection scope of the present invention
It is interior.
