As shown in figs. 1 to 6, the embodiment of the invention provides a kind of metal powder feeding devices, including mounting bracket 10, use
In the stone component 20 and at least one supply assembly 30 of printing stone, the stone component 20 includes stone plate 21 and scraper
22, the stone plate 21 is installed in the mounting bracket 10, and the scraper 22 is slidably mounted on one end of the stone plate 21
And enclose to set jointly with the stone plate 21 to form stone area 23, each supply assembly 30 includes feed bin 31 and vibrating motor
32, the vibrating motor 32 is installed on the feed bin 31, one end of the feed bin 31 be mounted in the mounting bracket 10 and
Positioned at the top of described 21 one end of stone plate, the other end of the feed bin 31 is equipped with for towards blowing in the stone area 23
Discharge port 34 is equipped with the regulating part 33 for adjusting 34 size of discharge port on the feed bin 31.
Specifically, the metal powder feeding device of the embodiment of the present invention, in use, metal feed powder is incorporated in feed bin 31
It is interior, and by adjusting the size of part adjustment discharge port 34, so that the frictional damping formed between metal feed powder in feed bin 31 is proper
Good to balance each other with self gravity, i.e. the state that remain stationary in feed bin 31 of metal feed powder is without falling;So, when the past paving of needs
When expecting that blowing carries out 3D printing in area 23, start vibrating motor 32, so that the vibration of certain amplitude, at this moment metal occur for feed bin 31
Feed powder just changes equilibrium state due to vibration, starts to be flowed out by discharge port 34;When needing to stop the blowing in stone area 23,
Vibrating motor 32 need to be only closed, feed bin 31 stops vibration, and metal feed powder is restored no longer to flow out in equilibrium state, just be led in this way
The length of starting 32 working time of vibrating motor is crossed, to realize the purpose for carrying out quantitative feeding in stone area 23, effectively
Ground reduces the waste of material, and promotes the accuracy of feed.Also, when the metal feed powder placed in feed bin 31 can be according to reality
Printing needs to select, such as can be stainless steel powder, wolfram steel powder or titanium valve, wherein by the friction between different metal feed powder
Damping is different, therefore in complete stone area 23 when blowing, can pass through the Oscillation Amplitude and discharge port 34 of adjusting vibrating motor 32
Size, with achieve the purpose that different materials can the equally applicable feed bin 31 realize quantitative feeding, there is splendid market to answer
Use prospect.
Further, the quantity of the feed bin 31 is two, and two feed bins 31 are located at the stone plate 21
The top at both ends.Specifically, two feed bins 31 are separately mounted to the left and right ends in stone area 23, are not sending in this way toward stone area 23
Before material, scraper 22 is moved to the left end extreme position in stone area 23, so that scraper 22 is located in one of feed bin 31 (such as left end
Feed bin 31) discharge port 34 rear, in this way after discharging a defective material in the complete stone area 23 of feed bin 31 of left end, scraper 22 is in stone
Towards right translation in area 23, the feed powder in stone area 23 is subjected to stone printing, that is, completes one layer of printing;When scraper 22 is moved to
After the extreme position of 23 right end of stone area, positioned at the stone in stone area 23 again of feed bin 31 of right end, when the feed bin 31 of right end is complete
After discharging a defective material in stone area 23, scraper 22, towards left, the feed powder in stone area 23 is spread in stone area 23
One layer of printing is completed in material printing again;It loops back and forth like this, so that printing effect obtains double raising, using effect is good.
Further, in the mounting bracket 10 two for adding toward addition metal feed powder in two feed bins 31
Expect window.Specifically, charging window is set by being located at the top of two feed bins 31 in mounting bracket 10, wherein charging window setting
The state of movable opening, it can the one end for the window that feeds is hinged in mounting bracket 10, so that operator can be at any time
Check that the surplus of the metal feed powder of feed bin 31 guarantees in order to add metal feed powder in feed bin 31 in time by the window that feeds
Feed bin 31 can persistently feed in stone area 23 during printing.
In the present embodiment, as shown in Figure 2-5, the feed bin 31 includes storing warehouse 311 and feeding warehouse 312, the storage
The upper end of stock bin body 311 is installed in the mounting bracket 10, and the discharge port 34 is set to the lower end of the storing warehouse 311,
The regulating part 33 is installed on the storing warehouse 311 at the discharge port 34, the upper end of the feeding warehouse 312 with
The lower end of the storing warehouse 311 connects and is connected to the discharge port 34, the oblique court in lower end of the feeding warehouse 312
It is extended to the stone area 23, the vibrating motor 32 is installed on the storing warehouse 311.Specifically, metal feed powder
It is stored in storing warehouse 311, feeding warehouse 312 is obliquely mounted between storing warehouse 311 and stone area 23, and feeding
The both ends of warehouse 312 are openning shape, when vibrating motor 32 start when, storing warehouse 311 starts to shake, at this time metal feed powder by
Discharge port 34 flows out, and feeding warehouse 312 guides the metal feed powder flowed out by the discharge port 34 on storing warehouse 311 to stone
The top in area 23 is later fallen into stone area 23, and after metal feed powder falls into specified amount in stone area 23, scraper 22 starts
Move back and forth in stone area 23, stone printing is carried out to metal feed powder.
In the present embodiment, as shown in Figures 4 and 5, the storing warehouse 311 includes level-one cavity 3111 and secondary cavity
3112, the upper end of the level-one cavity 3111 is installed in the mounting bracket 10, the week of the lower end of the level-one cavity 3111
Edge is enclosed equipped with the first choke 31111, and the upper end of the secondary cavity 3112 is connected on first choke 31111, institute
The periphery for stating the lower end of secondary cavity 3112 is enclosed equipped with the second choke 31121, and the upper end of the feeding warehouse 312 is connected to institute
It states on the second choke 31121, the lower end of the feeding warehouse 312 extends obliquely towards the direction among the stone plate 21
Setting, the regulating part 33 are installed on second choke 31121, and the vibrating motor 32 is installed on first necking
In portion 31111.Specifically, level-one cavity 3111 and secondary cavity 3112 are square-shaped, and level-one cavity 3111 is transversal
Area is greater than the cross-sectional area of secondary cavity 3112, wherein being located at the first choke 31111 of 3111 lower section of level-one cavity by four
Block inclined plate composition, and the lower end of four pieces of inclined plates extends towards the intermediate direction of level-one cavity 3111 obliquely, by level-one chamber
The lower section of body 3111 is shrunk to opening identical with the upper end size of secondary cavity 3112, and the upper end of secondary cavity 3112 then connects
It connects in the lower end of four pieces of inclined plates;Likewise, in the lower end of secondary cavity 3112 also by two pieces of inclined plates towards in-between direction
Extend obliquely, the lower end of secondary cavity 3112 is shrunk to discharge port 34.In this way when metal feed powder is placed on the level-one cavity
3111 and secondary cavity 3112 in when, the inclined-plane on inclined-plane and the second choke 31121 on the first choke 31111 is just twice
Certain barrier effect is played, allows the frictional damping having between metal feed powder to balance its own gravity, thus may be used
To realize that metal powder material is flowed out by discharge port 34 when the vibrating motor 32 being mounted on the first choke 31111 shakes, stop
When vibration, then metal powder material does not flow out.
In the present embodiment, as shown in figures 4-6, the feed bin 31 further includes transition warehouse 313, and the transition warehouse 313 connects
It is connected between second choke 31121 and the feeding warehouse 312, the regulating part 33 is mounted on the transition warehouse
