一種FDM型3D打印機熔融擠出裝置的制造方法

本實用新型(xing)涉(she)及3D打印(yin)機擠(ji)出裝置,尤其涉(she)及一(yi)種FDM型(xing)3D打印(yin)機的熔融材料擠(ji)出裝置。



背景技術:

3D打印技(ji)術(shu)已(yi)經誕生三十(shi)多(duo)年,經過(guo)長時間的(de)(de)發展,尤(you)其(qi)(qi)(qi)是最(zui)近幾(ji)年來的(de)(de)發展,其(qi)(qi)(qi)技(ji)術(shu)優越性已(yi)在眾多(duo)領域初步顯現出(chu)(chu)來,甚至在某些領域起著不可替代的(de)(de)作(zuo)用(yong),因此引起社會各界的(de)(de)廣泛關注。FDM型3D打印機以其(qi)(qi)(qi)設備簡單、價(jia)格低(di)廉、環保無污染等優點廣受消(xiao)費者青睞。現有的(de)(de)FDM 型3D打印機一(yi)般采(cai)用(yong)電機帶動(dong)(dong)一(yi)對(dui)驅動(dong)(dong)輪(lun)供絲(si)并提供擠出(chu)(chu)力,即用(yong)未熔(rong)(rong)融絲(si)材作(zuo)熔(rong)(rong)融材料的(de)(de)擠出(chu)(chu)推桿。但驅動(dong)(dong)輪(lun)提供的(de)(de)驅動(dong)(dong)力有限,驅動(dong)(dong)輪(lun)轉速達(da)到(dao)一(yi)定(ding)值后便會出(chu)(chu)現打滑(hua)現象或導致線(xian)材彎曲,因此擠出(chu)(chu)速度受到(dao)限制,不利(li)于打印效率的(de)(de)提高。



技術實現要素:

本實(shi)用新型所(suo)要解決的技術問題是通過改變擠出方式來(lai)提高(gao)擠出速度,從而提高(gao)打(da)印效率。

為解決上(shang)(shang)述技術問(wen)題,本實用新型(xing)提(ti)供一種FDM型(xing)3D打印機(ji)(ji)熔(rong)融擠出裝置,包括送(song)絲(si)機(ji)(ji)構(gou)、擠出機(ji)(ji)構(gou)、通(tong)(tong)氣(qi)孔開關、支撐板、噴頭(tou)、加熱套(tao)、熔(rong)料(liao)罐;加熱套(tao)置于(yu)(yu)熔(rong)料(liao)罐外側,下端通(tong)(tong)過安裝在熔(rong)料(liao)罐上(shang)(shang)的噴頭(tou)固定,熔(rong)料(liao)罐與(yu)擠出機(ji)(ji)構(gou)固定于(yu)(yu)支撐板上(shang)(shang);擠出機(ji)(ji)構(gou)由(you)(you)支撐架Ⅰ、電機(ji)(ji)Ⅰ、齒(chi)輪(lun)、齒(chi)條(tiao)、推桿、活塞(sai)(sai)組成,活塞(sai)(sai)上(shang)(shang)開有通(tong)(tong)氣(qi)孔,由(you)(you)固定于(yu)(yu)活塞(sai)(sai)上(shang)(shang)的通(tong)(tong)氣(qi)孔開關控(kong)制通(tong)(tong)氣(qi)孔的啟閉;通(tong)(tong)氣(qi)孔開關由(you)(you)外殼、永磁體滑(hua)塊、電磁鐵組成,電磁鐵固定于(yu)(yu)外殼上(shang)(shang),送(song)絲(si)機(ji)(ji)構(gou)置于(yu)(yu)活塞(sai)(sai)上(shang)(shang),送(song)絲(si)機(ji)(ji)構(gou)由(you)(you)電機(ji)(ji)Ⅱ、驅動輪(lun)、滑(hua)輪(lun)、支撐架Ⅱ、線(xian)材導(dao)套(tao)組成。

與現有技術相(xiang)比,本實(shi)用新型提(ti)(ti)供(gong)的(de)一種FDM型3D打(da)印機熔融擠(ji)(ji)出(chu)裝(zhuang)置(zhi)將送絲過程與擠(ji)(ji)出(chu)過程分離,可以快速送絲并(bing)提(ti)(ti)供(gong)較高的(de)擠(ji)(ji)出(chu)壓力,有利于提(ti)(ti)高擠(ji)(ji)出(chu)速度(du),提(ti)(ti)高打(da)印效(xiao)率。
