The powder filter device comprises a shell, a powder filter element, a reclaiming member and an air suction device, wherein the shell is provided with a suction port from which the dust powder is sucked; the powder filter element is arranged in the shell and used for partitioning the interior of the shell into a first space and a second space, wherein the suction port of the shell is communicated with the second space; the reclaiming member is arranged in the second space; and the air suction device is used for making the first space form a negative pressure state, guiding the dust powder sucked from the suction port into the second space, filtering the dust powder through the powder filter element and reclaiming the blocked powder in the reclaiming member.
Description
Technical field
The invention relates to a kind of powder filter device, refer to a kind of powder filter device that is applicable to the stereo shaping system especially.
Background technology
Rapid shaping technique (Rapid Prototyping, be called for short the RP technology) be to develop according to the notion that the construction pyramid is stacked into type layer by layer to form, its major technique feature is the agility of moulding, can automatically, fast the design of any complicated shape be converted to fast the physical model of 3D under the situation of mould and jig without any need for cutter.
RP technical development at present goes out to utilize the spray printing technology to produce the physical model of 3D in conjunction with the mode of carrier precision positioning technology, its mode of production is earlier one deck powder to be layed in the carrier top and to utilize inkjet technology spray printing high viscosity adhesive liquid on the part powder, make adhesive liquid and powder be stained with glutinous and curing, repeat above-mentioned operation always and pile up the physical model that to finish 3D layer by layer.
Yet; the existing stereoscopic moulding device of RP technology that adopts is when shop powder, printing and taking-up moulding product; the dust regular meeting of being kicked up causes the pollution of working environment; and become easily infected by on the entire job board of stereoscopic moulding device; normal in order to keep operation; prior art needs after carrying out a certain discontinuous running, will carry out the work of dust suction and cleaning maintenance.Yet, in cleaning course, often because of the careless moulding product of having damaged, or the member of destruction stereoscopic moulding device; In addition, high-frequency cleaning also can cause manpower and waste of time, has relatively improved the integral manufacturing cost, and if reduce cleaning frequency, again dust pollution is arranged and is difficult for keeping the anxiety of working space cleaning.
In view of this, how to develop a kind of powder filter device, to improve above-mentioned prior art disappearance, real for pressing for the problem of solution at present.
Summary of the invention
Main purpose of the present invention, be to provide a kind of powder filter device, the dust that can avoid existing grounding stereoscopic moulding device to be kicked up when shop powder, printing and taking-up moulding product causes the pollution of working environment, thereby need not rely on manpower to carry out the work of dust suction and cleaning maintenance continually, overcome simultaneously because of the moulding product of accidentally having damaged of cleaning course or the member of destruction stereoscopic moulding device, and cause the stereoscopic moulding device can't normal operation and shortcomings such as waste of manpower and time.
For reaching above-mentioned purpose, of the present invention one implements aspect for a kind of powder filter device is provided than broad sense, and the dust powder that is flown upward when drawing and filtering the stereoscopic moulding mechanism running comprises at least: housing, have suction inlet, and be provided with sucking thus the dust powder; The powder filter element is arranged in the housing, is separated into first space and second space in order to the inside with housing, and the suction inlet of its middle shell is communicated in this second space; Reclaim member, be arranged in second space; And air intake device, it is communicated with first space, with so that first space forms negative pressure state, the dust powder that suction inlet sucked is imported second space, by the powder filter element with the dust powder filter, and with the Powder Recovery that intercepts in reclaiming member.
