Abstract
A kind of heterogeneous powder mixing feed mechanism.The utility model devises a mechanism being used for powder bed while a variety of heterogeneous powder of feed.Its scheme is, more than two sets devices being made up of powder cabin and powder batcher of the close hanging side by side in top on the outside of powder bed, these bottom of device are fixed in same powder hopper, the powder tank of moveable powdering body is located at immediately below powder hopper outlet, can be accurately received the mixture from multiple powder cabins, quantitative heterogeneous powder fallen from powder hopper outlet.All powder batcher is exported on the inside of same powder hopper receiving port, and the powder of quantitative feed can be all fallen into this powder hopper.Each heterogeneous powder feed amount is decided by rotating shaft rotating speed and the duration of runs of respective powder batcher respectively.The rotation of each powder batcher rotating shaft makes the powder in its corresponding powder cabin be fallen into after converging into powder hopper in the powder tank of powdering body；Each powder batcher can both work independently, and only for a kind of powder is sent, be simultaneously operable again, while several heterogeneous powder of feed.
Description
Technical field
A kind of powder supplying mechanism is the utility model is related to, is to be related to a kind of mechanism that powder is supplied to powder bed specifically.
Background technology
Currently, powder bed applies more and more extensive, particularly increasing material manufacturing（3D printing）Rise, it is a variety of to have with powder bed
The increasing material manufacturing equipment of pass continues to bring out.The powder bed for increasing material manufacturing equipment occurred earliest is with increasing material for the mode of powder
Manufacture formation cylinder powder cylinder arranged side by side holds powder, and powder cylinder bottom portion has an elevating mechanism to support a piston, and piston moves up
One displacement, powder is pushed upwards an equivalent thickness, be sent to by powdering mechanism paving in the powder bed on working cylinder top, it is more
Remaining powder is scraped in excessive powder tank, completes to act for powder.There is overhead powder supplying mechanism again later, powder is contained in powder hopper
In, the powder quantitative mechanism motion certain angle under system control, a certain amount of powder is fallen on workbench, by powdering mechanism
Paving is sent in the powder bed on working cylinder top, and excessive powder is also scraped in excessive powder tank, completes to act for powder.Both mechanisms one
As can only a kind of powder of feed.
With the development of science and technology, there is the diversity of structure and inner materials in product.If its forming technology is related to
Powder bed, then need to a variety of heterogeneous powder of powder bed feed.For baroque single and mini-batch production product, it is desirable to increasing material
Manufacturing process carrys out figuration manufacture, and current powder bed increasing material manufacturing technique application is the most universal.However, as it was previously stated, increase at present
Material manufacture powder bed powder supplying mechanism can not simultaneously two kinds of powder of feed, thus can not realize become material part increasing material system
Make.
The content of the invention
In order to solve the above problems, the utility model devises one and is used for powder bed while a variety of heterogeneous powder of feed
Mechanism, the increasing for becoming the part of material in interlayer can be realized in the mixed-powder of the different heterogeneous powder proportions of different layers feed
Material manufactures.
The utility model solution to problem is：On the outside of powder bed more than two sets of the close hanging side by side in top by powder cabin with
The device of powder batcher composition, these bottom of device are fixed in same powder hopper, and the powder tank of moveable powdering body is located at
Powder hopper outlet immediately below, can be accurately received from powder hopper outlet fall from multiple powder cabins, quantitative heterogeneous powder
Mixture.The bottom plate of used two or more identical powder batcher is all fixed together with same powder hopper, owns
The outlet of powder batcher is on the inside of powder hopper receiving port, and the powder of quantitative feed can all fall into this powder hopper from several powder cabins
In.Various heterogeneous powder are quantified by respective powder batcher respectively, and the feed amount of various heterogeneous powder is decided by powder batcher
Internal rotating shaft rotating speed and the duration of runs.Rotating shaft rotation inside powder batcher causes under the powder in its corresponding powder cabin
Fall, powder is fallen into the powder tank of powdering body by batcher, powder hopper；Several powder batchers can both work independently, feed one
Kind powder, can work simultaneously again, while several heterogeneous powder of feed.
When supplying powder to powder bed every time, powdering body is had arrived at immediately below powder hopper, and all computers that obtain are for powder instruction
Rotating shaft operates certain time with certain speed under the control of the computer inside powder batcher, and the powder in corresponding powder cabin is fallen into
In powder hopper, then exported down and fallen in the powder tank of powdering body by powder hopper, powdering body is stopped and connect in all powder batcher
Powdering action is carried out after harvesting whole powder of this powdering, is sent mixed-powder in the powder bed on working cylinder top, it is unnecessary
Powder is scraped in excessive powder tank, is completed this and is supplied powder to powder bed.
This patent is using two or more powder batcher respectively by the parameter of computer settings in its corresponding powder cabin
Heterogeneous powder is fallen into by same powder hopper into the powder tank of same powdering body, can be as needed by setting ratio simultaneously to powder
The last a variety of heterogeneous powder of bed feed.
Brief description of the drawings
Accompanying drawing 1 is a variety of heterogeneous powder feed mechanism side schematic views of powder bed, and Fig. 2 is that a variety of heterogeneous powder of powder bed supply
Send mechanism front schematic view.
1 is powder cabin in figure, and 2 be another powder cabin, and the 3 powder batcher to be connected with powder cabin 1,4 be to be connected with powder cabin 2
Powder batcher, 5 be powder batcher 3 motor, 6 be powder batcher 4 motor, 7 be powder hopper, and 8 be band
The powdering body of powder tank, 9 be powder bed.
Embodiment
With reference to Fig. 1, Fig. 2, the embodiment that two kinds of heterogeneous powder mix feed is illustrated.
Two kinds of heterogeneous powder are stored in powder cabin 1, powder cabin 2 respectively first, then under the control of the computer, motor
5th, driving electricity 6 drives the inside rotating shaft of powder batcher 3, powder batcher 4 by given speed and time rotation, powder cabin respectively
1st, a certain amount of powder is dropped into powder hopper 7 by powder batcher 3, powder batcher 4 respectively in powder cabin 2, then from powder hopper 7
Outlet is dropped into the powder tank of powdering body 8 and mixed；After powder falling terminates, powdering body 8 drives the heterogeneous powder of mixing in powder tank along powder
The surface of last bed 9 carries out powdering motion, while powder further mixes in motion process, and is layered in powder bed 9.
