Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated. Should be understood that,Detailed description of the invention described herein only, for description and interpretation the present invention, is not limited to thisBright.
In the present invention, in the situation that not doing contrary explanation, " top, bottom " etc. is included in termIn the noun of locality only represent the orientation of this term under normal service condition, or be those skilled in the art reasonThat separates is commonly called as, and should not be considered as the restriction to this term.
Referring to Fig. 2, the invention provides a kind of three-dimensional printer with magnetic screen feeding device, compriseCasing 1 and be arranged on controller, movable stand in casing 1, be arranged on print.er port on movable stand,Print platform 2 and feeding device; Controller is electrically connected with movable stand can control movable stand and is printingPrint area top on platform 2 is mobile; Feeding device is connected to make print.er port with print.er portPrinting heating raw materials in the feeding device receiving is become to molten condition and be ejected on print platform 2Type; Print.er port comprise rotatable printing dish 3 and be arranged on multiple printheads 4 on printing dish 3 andThe discharging opening of printhead 4 is vertically towards print platform 2; Multiple feeding devices are corresponding one by one with printhead 4Assembling is to add the printing raw material of different colours in the printhead 4 to different; Wherein, as shown in Figure 1,Feeding device comprises feeding box 52, funnelform loading head 53 and the feeder sleeve 6 with bung 51; CollectionGlassware 53 is arranged on the bottom of feeding box 52 and is carried and printed raw material by feeder sleeve 6; Feeding box 52Inside be provided with magnetic screen 54, magnetic screen 54 is removably erected at loading head 53 and connects with feeding box 52Meet place.
By technique scheme, in feeding box 52, establish magnetic screen 54, and by magnetic screen 54Be erected at the junction of loading head 53 and feeding box 52, as operating personnel, to open bung 51 former by plasticsExpect from uncovered the pouring into of feeding box 52, because the effect plastic grain that is subject to gravity is piled up and falls,In dropping process, enter loading head 53 and enter feeder sleeve downwards through the through hole of magnetic screen 54 and carry outCarry. And in this process, magnetic screen 54 adsorbs the metallics being mixed in plastic grain,Stop itself and plastic grain together to fall, be stuck or wear and tear thereby protected three-dimensional printer to avoid it,Therefore save cost, improved operating efficiency. Meanwhile, by printhead independent on three-dimensional printer 4Be designed to multiple printheads 4, and by multiple printheads 4 be arranged on can the printing dish 3 of rotation on, manyIndividual feed reel 5 and printhead 4 one by one corresponding assembling so that different printhead 4 can be printed notWith the raw material of color or quality. Like this, when a printhead 4 on printing dish 3 complete this kind of color orAfter the printing of quality, rotate printing dish 3 just can be efficiently and easily by print time a kind of different color orAnother printhead 4 of quality raw material moves to 3 D-printing semi-finished product top to be continued to print. So canSwitch very rapidly different colours or quality, optimized printing changeover portion, also not only saved the time-write intervalImprove the printing effect of three-dimensional body.
In present embodiment, in order to strengthen the adsorption effect of magnetic screen 54 to metal impurities, increase magneticProperty filter screen 54 adsorption area, preferably on the inwall of feeding box 52 along circumferentially applying and be also provided with magnetic screen 54.
Further, in order significantly to improve removal of impurity effect, preferably, feeding device also comprises driving to be establishedFor 55, the two ends of driving arrangement 55 are fixed on magnetic screen 54 to drive by connecting rod 56 respectivelyMagnetic screen 54 is around self axial direction rotation. Like this, in reinforced process, driving arrangement 55 drivesMagnetic screen 54 slowly rotates, and has improved the absorption affinity to metal impurities, further the clean raw material of printing.
In present embodiment, in order to simplify the frame for movement of movable stand, be convenient to it and drive printhead 4 beatingPrint platform 2 tops and move or hover to print operation, preferably, movable stand comprises two sliding trays7, two elevating levers 8 and a hack lever 9; Wherein, two sliding trays 7 are set in parallel in print platformOn 2, the two ends of hack lever 9 are connected with sliding tray 7 respectively and can be past along the length direction of sliding tray 7Reciprocating cutter; Elevating lever 8 is arranged on the outside of sliding tray 7 and is connected to drive sliding tray with sliding tray 7The 7 direction liftings along vertical print platform 2.
In above-mentioned moving process, for the ease of regulating the particular location of the printhead 4 on printing dish 3,Make printing can cover any one point on whole print platform 2, expand print area, excellentSelection of land, printing dish 3 is connected with the bottom face of hack lever 9 by turning cylinder and printing dish 3 can be along rotatingThe axial direction of moving axis rotates, and turning cylinder can move along the length direction of hack lever 9.
In addition, control the rotation of printing dish 3 for the ease of staff's operated from a distance, preferably printing dishOn 3 periphery wall, along being circumferentially with strip tooth, on hack lever 9, be also provided with motor 10 and driven wheel 11,Driven wheel 11 be set in tooth on the turning cylinder of motor 10 and on driven wheel 11 can with strip toothEngagement. Like this, Long-distance Control motor 10 rotates, and is set in the driven wheel 11 in motor 10 rotating shaftsAlso start to rotate, and it is mutual to coil strip tooth on 3 periphery walls by the tooth on driven wheel 11 and printingMating reaction drives printing dish 3 synchronously to rotate, and next the required printhead 4 on dish 3 to be printed movesTo 3 D-printing object when top just disable motor stop printing dish 3 and rotate, now once change and print faceThe operation of look or texture material just can complete.
When printhead 4 sucks the raw material in feeder sleeve 6 while carrying out heating and melting in its cavity, in order to makeMany feeder sleeves 6 are not mixed and disorderly in order in fill process, avoid being mutually wound around and causing feeder sleeve 6 to stop upEven pull cracking and cause printing wastage of material, preferably, on the sidewall of casing 1, outwardly convex is formed withGathering sill 12, the movable end of feeder sleeve 6 passes gathering sill 12 and extends in printhead 4.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail, still, the present invention does not limitDetail in above-mentioned embodiment, within the scope of technical conceive of the present invention, can be to the present inventionTechnical scheme carry out multiple simple variant, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition each the concrete technology spy described in above-mentioned detailed description of the inventionLevy, in reconcilable situation, can combine by any suitable mode, for fear of needn'tThe repetition of wanting, the present invention is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present invention, also can be combined, as long as itsWithout prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
