本新型提供一種輔助供料裝置及具有輔助供料裝置的3D列印設備,用於將如泥漿般的漿料供料給3D列印機進行3D列印。如圖1所示為本新型具有輔助供料裝置的3D列印設備的結構示意圖,如圖2至圖8所示為本新型輔助供料裝置的剖視示意圖。The model provides an auxiliary feeding device and a 3D printing device with the auxiliary feeding device, which are used to feed slurry-like slurry to a 3D printer for 3D printing. Fig. 1 is a schematic diagram of the structure of a new 3D printing device with an auxiliary feeding device, and Figs. 2 to 8 are schematic sectional views of the new auxiliary feeding device.
如圖1所示,本新型具有輔助供料裝置的3D列印設備包括:一輔助供料裝置100、一3D列印機800以及一壓出供料機900。3D列印機800於本新型並未限制。壓出供料機900具有一儲料空間911和連通於儲料空間911的一壓出供料孔912,儲料空間911用於儲存漿料S。所述漿料S可為陶瓷泥漿,但不以此為限。As shown in Figure 1, the 3D printing equipment with auxiliary feeding device of the present invention includes: an
如圖1所示,壓出供料機900可為各式能經由推壓而將所儲存漿料S輸出而供料的供料機,於本實施例中則以本段後述為例進行說明:壓出供料機900包含一缸體91、一活塞92和一驅動器93,活塞92係可活動地伸入於缸體91內,儲料空間911形成於缸體91與活塞92之間,驅動器93則設置於缸體91且驅動活塞92相對於缸體91移動。壓出供料機900經由活塞92相對缸體91移動,以將儲存於儲料空間911內的漿料S經由活塞92的推壓而從壓出供料孔912輸出供料。As shown in FIG. 1, the
如圖1至圖3所示,輔助供料裝置100包含:一泵送結構1以及一步進馬達2,較佳還包含一輸料管4。As shown in FIGS. 1 to 3, the
泵送結構1包含一轉子11以及一定子12,較佳還包含一撓性結構13。轉子11為一螺旋桿且可轉動地穿插於定子12之內。定子12的內壁形狀與轉子11的形狀相對應,換言之,定子12的內壁形狀係為對應螺旋狀,使定子12之內形成一螺旋通道(未標示元件符號),且泵送結構1(例如定子12)還開設有一入料孔121和一出料孔122。定子12的內壁與轉子11的外壁之間共同形成有一容料空間14,入料孔121和出料孔122皆連通於容料空間14,且入料孔121連接於壓出供料機900的壓出供料孔912,出料孔122則連接於3D列印機800。The
步進馬達2設置於泵送結構1,於本實施例中的步進馬達2則是設置於定子12的一端並驅動轉子11相對於定子12旋轉,具體而言則是步進馬達2的轉軸(未標示元件符號)在定子12內與轉子11的一端連接,以利用轉軸帶動轉子11在前述螺旋通道內相對於定子12旋轉。The
具體而言,泵送結構1為一迴轉容積型的單軸螺旋泵送結構,且如圖3所示,轉子11在任意處的截面皆為圓形,定子12在供轉子11穿插的前述螺旋通道的任意處的截面則為長圓形,且此一圓形可滑移地適配於此一長圓形之內(即:轉子11可滑移地適配於定子12之內),以在轉子11相對於定子12旋轉時,此一圓形將會在此一長圓形的兩端之間來回移動,也就是轉子11將會在定子12的前述螺旋通道內一邊旋轉且一邊在此一長圓形的兩端之間來回移動,此由圖4至圖8所示轉子11分別在0度旋轉至45度、90度、135度以及180度的各個剖視示意圖即可看出。再加上轉子11與定子12之間係彼此緊密接觸而形成氣密,因此當轉子11一開始旋轉將會立即產生強勁的自吸作用,進而使被吸入並充填於容料空間14內的漿料S得能順著泵送結構1的螺旋的前進方向從入料孔121連續不斷地從出料孔122吐出,所吐出的漿料S則是供料給 3D列印機1來進行3D列印。Specifically, the
泵送結構1較佳還可包含一撓性結構13,撓性結構13連接於步進馬達2的前述轉軸與轉子11的前述一端之間,撓性結構13於本實施例中係位於定子12內,如此一來,步進馬達2即可經由撓性結構13驅動轉子11旋轉。撓性結構13可為萬向接頭、鋼纜或鏈條,藉由撓性結構13的可撓特性,以將轉子11在旋轉時所發生的震動或晃動減至最低。又,撓性結構13之外還可進一步包覆一撓性套15(見圖2)。Preferably, the
此外,泵送結構1如圖2所示還可包含有一套管3,詳如本段後述。撓性結構13具體係連接於步進馬達2的前述轉軸與轉子11的前述一端之間,套管3則連接於定子12與步進馬達2之間,使撓性結構13得以收容於套管3內,前述入料孔121開設於套管3,至於出料孔122則仍開設於定子12,套管3的內壁與撓性結構13的外壁之間共同形成有連通於容料空間14的一緩衝空間31,入料孔121連通緩衝空間31,如此以使壓出供料機900能將漿料S先供料至緩衝空間31內緩衝,再利用泵送結構1的自吸作用而將緩衝空間31內的漿料S進一步吸入前述容料空間14內。其中,套管3的內壁形狀並沒有像定子12一樣具有與轉子11的形狀相對應的前述對應螺旋狀,套管3的內壁形狀可為如圖2所示的平坦壁面,但不以此為限。必須說明的是,在不具有套管3的前述實施例中,緩衝空間31則是共同形成於定子12的內壁與撓性結構13的外壁之間。In addition, the
套管3對應入料孔121設有一入料連接器123,定子12對應出料孔122設有一出料連接器124,壓出供料機900的缸體91對應壓出供料孔912設有一對接連接器913;入料連接器123和對接連接器913彼此對接,使壓出供料機900所壓出的漿料S能經由彼此對接的入料連接器123和對接連接器913而對泵送結構1供料;出料連接器124則連接有一輸料管4並經由輸料管4而連接3D列印機800,使泵送結構1所吐出的漿料S能經由輸料管4而供料給3D列印機800。再者,轉子11係為連續螺旋狀且線性延伸的螺旋桿(外螺旋狀),定子12則為對應線性延伸的一筒柱(筒柱內的前述螺旋通道則為對應內螺旋狀)。The
綜上所述,本新型相較於先前技術主要具有以下功效:由於輔助供料裝置100具有強勁的自吸作用,能將來自於壓出供料機900的漿料S吸入並充填於容料空間14內,因此能減輕壓出供料機900在壓出時的負荷;再者,藉由輔助供料裝置100的特殊結構設計:可為螺旋桿的轉子11、具有對應螺旋通道的定子12以及共同形成於轉子11與定子12之間的容料空間14,使泵送結構1的兩端分別具有強勁的自吸作用以及相對的漿料S吐出作用,因此能精確吐出所需的漿料S的量,即使停止驅動轉子11旋轉也不會發生漿料S逆流現象;三者,藉由以步進馬達2驅動泵送結構1,因此具有驅動動力隨傳隨到以及說停就停的效果,因此適用於已能精確吐出所需漿料S的量的泵送結構1。In summary, compared with the prior art, the present invention mainly has the following effects: because the
以上所述者,僅為本新型之較佳可行實施例而已,非因此即侷限本新型之專利範圍,舉凡運用本新型說明書及圖式內容所為之等效結構變化,均理同包含於本新型之權利範圍內,合予陳明。The above are only the preferred and feasible embodiments of the present model, and the scope of the patent of the present model is not limited as a result.
