Detailed description of the invention
Refer to shown in Fig. 1, for the nozzle structure 100 of 3 D-printing device of the present utility model, comprising: a load bearing seat 10；One feed module 20, it is arranged at above this load bearing seat 10, and also include feed unit 21 and a feed motor 22, it is adapted to provide for a wire rod 200 to being arranged in the trunnion 31 below this load bearing seat 10, and outside this trunnion 31, it is provided with a heating module 32, the wire rod 200 delivered within this trunnion 31 is added heat fusing, and forms the wire rod 200 of molten state, then sprayed by the nozzle 33 being located at this trunnion 31 end；One drives module 40, has a driving motor 41, and drives gear 42, and this driving motor 41 is arranged at above this load bearing seat 10, and connects this driving gear 42 by a drive shaft 43；And a fluted disc 51, it is arranged at below this nozzle 33, and be connected with this load bearing seat 10 by a fluted disc axle 52, also couple with this driving gear 42 simultaneously, wherein this fluted disc 51 has with this fluted disc axle 52 hole 531 that circumferentially formula arrangement and aperture size differ as the center of circle, 532, when the running of this driving motor 41 drives this driving gear 42, this driving gear 42 drives this fluted disc 51 therewith, this fluted disc 51 is made to rotate, make those holes 531, 532 can be respectively to should the jet hole (not shown) of nozzle 33, and then change the width printing circuit, to maintain the fineness of printing shaping.
Further, as shown in Figure 2, fluted disc schematic top plan view for the nozzle structure of 3 D-printing device of the present utility model, although having with this fluted disc axle 52 three holes 531,532,533 that circumferentially formula arrangement and aperture size differ as the center of circle on this fluted disc 51, and the aperture size of those holes 531,532,533 is respectively 0.3mm, 0.6mm, 1mm, but the aperture size being arranged at the pore quantity on this fluted disc 51 and hole is not limited thereto, and the aperture size of those holes is in the range of 0.1～1mm.
Yet further, as it is shown on figure 3, when this nozzle 33 arranges in pairs or groups the hole printing shaping of larger aperture, then can print with wider printing circuit A1 on print platform 60, so being applied to print inside larger area or object；Otherwise, as shown in Figure 4, when this nozzle 33 arranges in pairs or groups the hole printing shaping of smaller aperture due, then can print with narrower printing circuit A2 on print platform 60, so being applied to print the thin portion of less area or object appearance part.Therefore, when equal area printing shaping, if this nozzle 33 is arranged in pairs or groups, the hole of larger aperture prints, owing to printing the minimizing of number of, lines (number of times), then can be faster than the hole print speed of collocation smaller aperture due, and then shorten total time-write interval.
Therefore this utility model provides the nozzle structure of a kind of 3 D-printing device, fluted disc is provided with multiple various sizes of hole, when larger area need to be printed or object is internal, the hole of large-size can be replaced with, and when thin portion or the object appearance part of less area need to be printed, it is replaced with the hole of reduced size again, thus, then can select more suitably jet size according to the position of molding object or print area size, not only can reduce the time of printing shaping, also can maintain the fineness of printing shaping.
In sum; it is only preferred embodiment of the present utility model, the most therefore limits to protection domain of the present utility model, the equivalent structure change that every utilization this utility model description and accompanying drawing content are done; all reason is with being contained in the range of this utility model, illustrates in advance.
