Embodiment
Below in conjunction with the accompanying drawings, the powder feed system to the utility model and the 3D printing equipment with the powder feed system are done and are had
The explanation of body.
As shown in Figure 1, one embodiment of the utility model provides a kind of powder feed system, including at least two sets of dust feeders, often
Set dust feeder is controlled by control system, and be mutually independent operation.Dotted line in figure represents dust feeder and control system
It is electrically connected and/or signal connects, conveying is electric energy and/or control signal.Each dust feeder is equipped with a conforming particle and goes out
Mouthful.Each conforming particle outlet is tightly connected by the printing cabin of single pipeline and 3D printing equipment, is ensured in dust feeder
Raw material powder can not be mixed with other materials enter printing cabin in.Solid line in figure represents dust feeder and 3D printing
The actual connection of equipment.Control system controls at least two sets of dust feeders, and therefrom selection conveys raw material kind needed for next program print
The dust feeder of class starts, and exports required raw material powder by the outlet of its conforming particle and gives 3D printing equipment.It is by controlling
System, the utility model can realize the supply of automatic switchover raw material types.
When needing replacing raw material during 3D printing, expect before control system control conveying (preceding material, that is, more move
Make the raw material that use before) dust feeder be stopped, (rear material, that is, replacement act it to material after being then turned on conveying
The raw material used afterwards) dust feeder, be allowed to provide for printing cabin and another print raw material powder.In this way, complete for
The work that cabin conveys two kinds of raw material powders is printed, avoids the problem of preceding material of cleaning caused by reloading using same equipment is difficult.
Some aviation parts are processed, it is necessary to first use titanic alloy machining bottom, then use using 3D printing technique for example, working as
Nickel alloy processes the first half.In this process, using the powder feed system of the utility model, titanium alloy powder and nickel can be closed
Bronze end is respectively placed in different dust feeders, is individually for printing cabin feed, is eliminated to reload and is removed the difficulty of preceding material, also keeps away
Exempted from because clear up it is unnet before expect and caused by be mixed with titanium alloy in the first half and cause the generation of product defect.
It should be noted that dust feeder described in the utility model, its structure is consistent in theory, but is not arranged
