在一实施方式中,一种打印组件,所述的打印组件包括:对称设置的落料导轨、若干打印导轨、若干落料机构以及若干打印机构;各所述打印导轨与各所述落料机构分别设置于两个对称设置的所述落料导轨之间;至少一所述打印导轨上滑动设置一所述打印机构。
在一实施方式中,一种3D打印设备,包括打印组件,所述的打印组件包括:对称设置的落料导轨、若干打印导轨、若干落料机构以及若干打印机构;各所述打印导轨与各所述落料机构分别设置于两个对称设置的所述落料导轨之间;至少一所述打印导轨上滑动设置一所述打印机构。
上述打印组件及3D打印设备,通过将若干打印导轨、若干落料机构以及若干打印机构集成设置于对称设置的落料导轨之间,从而可实现各落料机构与各打印机构沿落料导轨进行同步往复运动,这样可实现连续打印,以便于有效提升打印效率,同时极大节约设备占地空间。
下面结合具体实施例对所述打印组件进行说明,以进一步理解所述打印组件的发明构思。请参阅图1,一种打印组件10,所述的打印组件包括:对称设置的落料导轨100、若干打印导轨200、若干落料机构300以及若干打印机构400;各所述打印导轨200与各所述落料机构300分别设置于两个对称设置的所述落料导轨100之间;至少一所述打印导轨200上滑动设置一所述 打印机构400。
具体地,落料导轨100与打印导轨200均为运动模组,其具体结构可参见现有技术中的3D打印机用的打印头与铺砂器的移栽运动模组,在本实施例中不再详述。其中,打印导轨200与落料机构300的具体数量根据实际打印需求设置安装。在其中一实施例中,两个对称设置的落料导轨100间隔设置于打印设备的支撑框架上。在其中一实施例中,各所述打印导轨200与各所述落料机构300相互连接,并设置于对称设置的两个所述落料导轨100之间。在其中一实施例中,各所述打印导轨200与各所述落料机构300相互间隔设置于两个对称设置的所述落料导轨100之间。即,各所述打印导轨200与各所述落料机构300之间可以相互连接设置也可以相互间隔设置,而无论何种设置方式由于其均随落料导轨运动可实现同步往复运动,因此其安装方式在本实施例中不做具体限制。这样,通过启动对称设置的落料导轨100,则可实现带动安装于落料导轨100上的落料机构300与打印导轨200同步运动。当完成一个方向的行程打印工作后,进一步通过控制落料导轨100朝相反方向运动,则可对应实现落料机构300与打印导轨200同步朝相反方向运动。也就是说,通过控制落料导轨100运动方向在一定行程范围内正反方向运动,从而可实现落料机构300与打印导轨200的循环往复式运动。在此过程中,可以根据实际打印需求安装多个落料机构与打印导轨,从而可以实现打印与落料同步进行,并连续地进行整个打印过程,由此可有效提升打印效率。需要说明的是,当打印导轨200的安装数量大于等于2时,至少保证其中一个打印导轨200滑动设置有打印机构400,这样实现打印机构400能够沿打印导轨200移动实现与落砂方向垂直方向的打印工作。也就是说,有部分打印导轨200可以不设置安装打印机构400,这种情况可结合下述实施例说明。
请再次参阅图1,在其中一实施例中,两个所述落料导轨100之间至少设置有一横梁500,每一所述横梁500对应安装一所述打印导轨200。即,所述横梁500为支撑设置打印导轨200的结构。这样,通过设置横梁500可便于更加稳定地安装打印导轨200,且可有效避免打印导轨200与落料导轨100之间彼此相互运动时受到影响。需要说明的是,打印导轨200可以直接设置 于两个落料导轨100之间,即无需设置横梁支撑,但是设置横梁能够更加保障打印导轨与落料导轨在运动中相互受到影响。

下面结合具体实施例对所述3D打印设备进行说明,以进一步理解所述3D打印设备的发明构思。请参阅图6,一种3D打印设备10,所述的3D打印设备10包括:支撑框架100、集成设置于所述支撑框架的打印组件200以及工作箱机构300;所述打印组件200包括对称设置的落料导轨210、若干打印导轨220、若干落料机构230以及若干打印机构240,各所述打印导轨220与各所述落料机构230分别设置于两个所述落料导轨210之间,至少一所述打印导轨220上滑动设置一所述打印机构240;两个所述落料导轨210设置于所述支撑框架100的对称两侧;所述工作箱机构300包括集成设置的工作箱310与顶升件320,所述顶升件320用于顶升所述工作箱310的底板沿垂直方向升降,所述工作箱310与所述顶升件320活动穿设于所述支撑框架100的内部。
具体地,在其中一实施例中,请继续参阅图6,支撑框架100包括若干支柱110与连接杆120,各个支柱110间隔设置,并通过连接杆120相互连接。优选地,支撑框架100沿X轴方向设置三个支柱,沿Y轴方向设置四个支柱。 这样所构成的支撑框架100结构相对更加稳定,且能够有效节约设备用材。进一步地,支撑框架100的对称两侧分别设置有落料导轨210。具体地,两个落料导轨210设置于支撑框架100的沿Y轴方向的支柱110的顶端。其中,打印机构240内存放有喷涂材料,用于打印形成产品轮廓。落料机构230内存放有基础材料,用于铺设产品层,例如,基础材料为砂料。在其中一实施例中,支撑框架100的对称两侧开设有进出口。具体地,进出口由两个间隔设置的支柱形成,其中要求工作箱机构300的宽度小于进出口的宽度,这样使得工作箱机构300可以由支撑框架100的一侧滑进支撑框架的内部,以便于打印机构与落料机构在工作箱上打印产品,打印后滑出至支撑框架的另一侧,或者由同侧进入并滑出,具体工作箱机构的移动路径可根据实际工序安排进行确定,在本实施例中不做具体限制。工作箱机构300的工作箱为承载打印产品的机构,顶升件为驱动工作箱底板的机构,当打印机构与落料机构配合进行打印工作时,产品在工作箱上成型,通过顶升机构逐渐降低工作箱底板高度,从而可在工作箱的底板上逐渐堆叠打印产品。
在其中一实施例中,工作箱310集成设置于顶升件320的顶部。这样,通过将顶升件320与工作箱310集成设置为一体式结构,可便于实现快速整体性转移工作箱机构。这样相较于现有技术中仅转移工作箱的方式,可有效节约打印等待时间,即当打印完毕的工作箱与顶升件整体移出之后,空的工作箱和顶升件可以紧接着就位,定位要求降低,可保证工作箱底板水平稳定而不受顶升件与工作箱底板地位影响,从而可以实现快速连续打印的同时,保证更加高效的打印精度。

优选地,顶升件320还包括相互滑动连接的若干平衡升降柱324与安装于所述传动机构321上的若干滑块325,每一所述滑块325连接一所述平衡升降柱324。其中,靠近所述工作箱底板的所述平衡柱324与所述工作箱的底板连接,靠近所述固定板323的平衡升降柱324与固定板323连接。例如,与固定板连接的平衡升降柱324与连接工作箱的底板的平衡柱324相互直接滑动连接。这种结构类似理解成相互套设的管柱,彼此可伸长或收缩。例如,与固定板连接的平衡升降柱324与连接工作箱的底板的平衡柱324之间还设置有第三根平衡升降柱。具体设置的第三根平衡升降柱的数量可根据运动机构的运动行程确定增设。优选地,在传动机构321的顶部的对称两侧设置所述滑块,每一所述滑块配合连接对应的一所述平衡升降柱。当需要升高工作箱的底板时,通过启动传动机构321带动运动机构322上升,由此传动机构的高度位置提升,使得滑块连接的平衡柱提升,而连接该平衡柱的其他平衡柱彼此错位提升,从而支撑整个工作箱底板。同理,工作箱的底板需要下降时,传动机构带动下各个平衡升降柱之间相互靠近收回,从而同步实现将工作箱的底板降低高度位置。
为了更加稳定地支撑工作箱,在一优选实施例中,请继续参阅图7,所述安装平台330上设置有支架340,所述支架340与所述工作箱的壳体311连 接。具体地,所述支架340安装于所述壳体的底边周缘。其具体连接方式可以是固定连接方式或可拆卸式连接方式,具体结构在本实施例中不做限定。这样,通过设置支架340有利于更加稳定地支撑工作箱。为了便于人工推拉工作箱机构,在一优选实施例中,所述支架340上设置有推拉把手341。这样工作人员仅仅需要通过推拉把手341即可推动整个工作箱机构移动。

在一个实施例中,请参阅图11,图11为本发明一个具体实施例的3D打印设备的等轴结构示意图。本发明提供的3D打印设备包括支撑框架4、打印组件和工作箱7机构。
其中,打印组件和工作箱7机构集成设置于支撑框架4,且打印组件包括落料导轨5、若干打印导轨6、若干落料机构8以及若干打印机构10,各打印导轨6与各落料机构8设置于落料导轨5上,至少一打印导轨6上滑动设置一打印机构10。工作箱7机构包括集成设置的工作箱7与顶升件,顶升件用于顶升工作箱7的底板沿垂直方向升降,工作箱7与顶升件活动穿设于支撑框架4的内部。
打印时,落料机构8沿落料导轨5进行铺料,打印机构10在一层铺砂完成后,沿打印导轨6进行打印,打印一次完成后,打印导轨6沿着落料导轨5移动一定距离后,打印机构10继续沿打印导轨6进行打印,如此循环直至打印完一层。一个打印循环完成后,顶升机构19带动工作箱7底板下降一个高度,继续重复铺料、打印循环。如此往复,直至打印任务结束。
应用本发明提供的3D打印设备,通过将打印组件的落料导轨5、打印导轨6、打印机构10以及落料机构8集成设置于支撑框架4上,实现打印机构10与落料机构8能够沿落料导轨5同步往复运动,从而有效提高了3D打印设备的打印效率;并通过将工作箱7与顶升件集成设置于一体,并整体活动穿设于支撑框架4的内部,从而可减少工作箱7与顶升件的定位次数,使得定位要求降低,从而可保证工作箱7底板水平稳定而不受顶升件与工作箱7底板定位影响,从而可以实现快速连续打印的同时,保证更加高效的打印精度。且通过上述设置,结构紧凑,空间占用小,成本低,有利于进入普通大众生活中进行使用。

对于落料导轨5,在一实施例中,落料导轨5成对设置,且两个落料导轨5设置于支撑框架4的对称两侧;各打印导轨6与各落料机构8分别设置于两个落料导轨5之间。
具体地,落料导轨5与打印导轨6均为运动模组,其具体结构可参见现有技术中的3D打印机用的打印头与铺砂器的移栽运动模组,在本实施例中不再详述。其中,打印导轨6与落料机构8的具体数量根据实际打印需求设置安装。在其中一实施例中,两个对称设置的落料导轨5间隔设置于打印设备的支撑框架4上。在其中一实施例中,各所述打印导轨6与各所述落料机构8相互连接,并设置于对称设置的两个所述落料导轨5之间。在其中一实施例中,各所述打印导轨6与各所述落料机构8相互间隔设置于两个对称设 置的所述落料导轨5之间。即,各所述打印导轨6与各所述落料机构8之间可以相互连接设置也可以相互间隔设置,而无论何种设置方式由于其均随落料导轨5运动可实现同步往复运动,因此其安装方式在本实施例中不做具体限制。这样,通过启动对称设置的落料导轨5,则可实现带动安装于落料导轨5上的落料机构8与打印导轨6同步运动。当完成一个方向的行程打印工作后,进一步通过控制落料导轨5朝相反方向运动,则可对应实现落料机构8与打印导轨6同步朝相反方向运动。也就是说,通过控制落料导轨5运动方向在一定行程范围内正反方向运动,从而可实现落料机构8与打印导轨6的循环往复式运动。在此过程中,可以根据实际打印需求安装多个落料机构8与打印导轨6,从而可以实现打印与落料同步进行,并连续地进行整个打印过程,由此可有效提升打印效率。需要说明的是,当打印导轨6的安装数量大于等于2时,至少保证其中一个打印导轨6滑动设置有打印机构10,这样实现打印机构能够沿打印导轨6移动实现与落砂方向垂直方向的打印工作。也就是说,有部分打印导轨6可以不设置安装打印机构10,这种情况可结合下述实施例说明。
在其中一3D打印设备的实施例中,两个所述落料导轨5之间至少设置有一横梁,每一所述横梁对应安装一所述打印导轨6。即,所述横梁为支撑设置打印导轨6的结构。这样,通过设置横梁可便于更加稳定地安装打印导轨6,且可有效避免打印导轨6与落料导轨5之间彼此相互运动时受到影响。需要说明的是,打印导轨6可以直接设置于两个落料导轨5之间,即无需设置横梁支撑,但是设置横梁能够更加保障打印导轨6与落料导轨5在运动中相互受到影响。
在其中一3D打印设备的实施例中,两个所述落料导轨5之间滑动设置有一所述横梁,所述横梁背离所述打印导轨6的一侧设置有一所述落料机构8。在本实施例中,打印机构10通过横梁与落料机构8集成设置,打印机构10随着落料机构8一起沿落料导轨5往复移动。即,在正常运行时,落料机构8沿落料导轨5移动进行落料,在此过程中打印机构10随落料机构8一起移动,但打印机构10不进行打印,而在打印机构10随落料机构8返回移动时实现打印。即,落料机构8进程中进行落料操作,然后回程时进行打印操作。
在另一3D打印设备的实施例中,两个所述落料导轨5之间滑动设置有两个所述横梁,所述落料机构8设置于两个所述横梁之间,且各所述横梁背离所述落料机构8的一侧均安装有所述打印机构10。在本实施例中,在落料机构8的两侧分别设置打印机构10,并且集成在同一个落料导轨5上,两个打印机构10随着落料机构8一起沿落料导轨5往复移动。即在正常运行时,落料机构8沿落料导轨5向右移动进行落料时,左侧打印机构10随落料机构8一起移动并进行打印;而在落料机构8沿落料导轨5向左返回落料时,右侧打印机构10随落料机构8一起移动并进行打印。即,落料机构8进程中进行落料操作的同时进行打印,然后回程时同样地同时进行打印操作。这样可实现连续打印操作,而不用等待落料结束后再进行打印,打印效率相对较高。
在另一3D打印设备的实施例中,两个所述落料导轨5之间滑动安装有一所述横梁,所述横梁的两侧分别安装有一所述落料机构8。在本实施例中,通过在安装打印机构10的横梁的两侧分别设置一落料机构8,并且集成在同一个落料导轨5上,打印机构10随着落料机构8一起沿落料导轨5往复移动。即,在正常运行时,右侧落料机构8沿落料导轨5向右移动进行落料时,打印机构10随右侧落料机构8一起移动并进行打印;而在落料机构8沿落料导轨5向左返回落料时,打印机构10随左侧落料机构8一起移动并进行打印。即,通过设置一套打印机构10配合两套落料机构8在往返方向实现连续打印,而落料分别由两个落料机构8执行,这样可便于连续不停止打印操作,而不需要因加料而中断打印操作。
在其中一3D打印设备的实施例中,两个所述落料导轨5之间滑动设置有两个所述横梁,所述落料机构8设置于两个所述横梁之间,且两个所述横梁之间沿垂直方向跨接有拱形龙门机构,其中一所述横梁上安装有所述打印机构10,并通过所述拱形龙门机构滑动至另一所述横梁。在其中一实施例中,所述拱形龙门机构包括拱形滑轨与活动设置于所述拱形滑轨两端的连接块,所述连接块与所述打印机构10活动连接。具体地,所述打印机构10包括滑动块与设置于所述滑动块上的打印头,所述滑动块活动安装于所述打印导轨6上。在一优选实施例中,所述滑动块与所述连接块转动连接。 具体地,滑动块安装于打印导轨6上,并随打印导轨6带动打印头沿打印导轨6往复运动,当需要将打印头通过拱形龙门机构转换至另一打印导轨6运动时,则首选将滑动块拆离打印导轨6,并转动滑动块与连接块的安装角度,使得打印头沿拱形滑轨滑动至另一侧的打印导轨6处。同理,将滑动块安装至该侧的打印导轨6上,然后使得打印头沿该侧打印导轨6运动。在本实施例中,通过在落料机构8的上方设置拱形龙门机构,打印机构10随着落料机构8一起沿落料导轨5往复移动。即在正常运行时,落料机构8与打印机构10同步沿落料导轨5向右打印完成一层后,打印机构10通过拱形龙门机构跳转至落料机构8的另一侧,落料机构8与打印机构10沿落料导轨5向左返回时,依然采用落料与打印同步进行,大大提高了设备效率。即,采用一套打印机构10,通过拱形龙门机构实现在两个打印导轨6的安装,继而实现往返同时进行打印。
在另一3D打印设备的实施例中,两个所述落料导轨之间滑动设置有两个所述横梁,所述落料机构设置于两个所述横梁之间,且两个所述横梁的一端之间沿水平方向跨接有拱形龙门机构,其中一所述横梁上安装有所述打印机构10,并通过所述拱形龙门机构滑动至另一所述横梁。在本实施例中,通过在落料机构的一端侧面设置拱形龙门机构,打印机构10随着落料机构一起沿落料导轨往复移动。在一优选实施例中,所述打印机构10包括打印头、第一连接部以及第二连接部,所述第一连接部的一端与所述打印头连接,且所述第一连接部活动设置于所述打印导轨6上,所述第二连接部与所述第一连接部一体设置,且所述拱形龙门机构与所述第二连接部连接。这样,通过在两个横梁之间跨接所述拱形龙门机构,使得所述拱形龙门机构的一端连接打印机构10,另一端连接横梁,当驱动打印头由一侧横梁上的打印导轨6滑出后,其会沿着水平方向设置的拱形龙门机构滑动至另一侧的横梁上,进一步通过将第一连接部与另一侧横梁上打印导轨6滑动连接时,从而实现打印机构10在另一侧横梁进行打印。即在正常运行时,落料机构与打印机构10同步沿落料导轨5向右打印完成一层后,打印机构10通过拱形龙门机构转至落料机构的另一侧,落料机构与打印机构10沿落料导轨5向左返回时,依然采用落料与打印同步进行,大大提高了设备效率。
为了减小落料机构在运动过程中对打印机构10产生的振幅影响,在其中一实施例中,每一所述横梁的两端与每一所述落料机构的两端均分别安装有滑块,各所述滑块与所述落料导轨滑动连接。即,落料导轨上设有双滑块,分别与落料机构和横梁连接,这样可以减小落料机构在运动过程中对打印机构10产生的振幅影响,从而可提高打印精度。
为了提高打印产品的固化速度,在其中一实施例中,各所述落料机构的侧面均设置有加热件。其中,加热件可以是电加热圈或电加热块。这样,通过启动加热件有利于对落料机构下端成型的产品进行快速固化,以提升打印效率。
对于落料导轨5,以上说明了其成对设置的多种设置方式,根据需要落料导轨5也可以单独设置。与上述实施例不同,在另一实施例中,落料导轨5上滑动连接有安装部件,打印导轨6和落料机构8分别对应的与安装部件固定连接。也就是将打印机构10与落料机构8集成,在落料导轨5的滑块上安装连接部件,连接部件具体可以为连接板24,连接板24上分别安装落料机构8与打印导轨6,打印导轨6上安装打印机构10。该实施例中使用单个落料导轨5与单个打印导轨6即可,实现低成本完成设备打印与铺料功能。
在上述各3D打印设备的实施例中,还包括与支撑框架4相独立设置的混料平台,请参阅图11,混料平台包括支撑主体15和放置于支撑主体15上的混料机13、用于量取物料的称量称和用于盛放并转移物料的盛料杯12。也就是混料平台与主设备分离,一方面可以降低设备高度、另外一方面可以实现灵活布局。称量称具体可以为电子称14,根据需要也可以采用其他称量设备。需要混料时,使用称量称进行量取合适的原料以及所需的液料,使用盛料杯12加入混料机13进行混合。混合完毕后,使用盛料杯12将混好的原料加入3D打印设备的加料装置9。然后再次进行上述过程,直至加料装置9装满混好的原料。支撑主体15具体可以为上下多层设计的支撑平台,其下部放置所需不同液料品类,上部放置混料机13、称量称、盛料杯12。根据需要,支撑主体15也可以采用支撑框架或支撑柜等结构。
在上述各3D打印设备的实施例中,还包括气源产生系统,气源产生系统包括气源泵和储气装置,气源泵与储气装置之间通过管路连通,且管路 内设置有单向阀,储气装置设置于单向阀的后方。也就是本3D打印设备自带气源产生系统。气源泵具体可通过电机带动,气源泵产生气体,为防止气体倒流,气源泵与储气装置之间设置单向阀,单向阀只允许由气源泵向储气装置的方向通过。储气装置具体可以为储气罐。通过上述结构设置,自带气源,进而降低了对使用场景的要求。
进一步地,管路内连接于气源泵的后方依次设置有过滤器和稳压阀。也就是气源泵后设置过滤器,过滤器后设置稳压阀,稳压阀后设置单向阀,气源泵产生的压缩空气首先由过滤器进行一级过滤,然后经过稳压阀稳压后通过单向阀进入储气装置,储气装置内储存产生的气体。
更进一步地,储气装置上设置有用于检测储气装置内气压的压力检测装置。压力检测装置具体可以为压力传感器,也可以为压力表等。通过压力检测装置的设置,能够实时获取储气装置内的压力,从而能够进行储气量的控制。
为了实现自动控制,还包括控制器,压力检测装置和气源泵分别与控制器电连接,控制器用于在压力检测装置反馈的压力值小于第一预设值时控制气源泵启动,而当压力检测装置反馈的压力值等于第二预设值时控制气源泵停止,第二预设值不小于第一预设值。以压力检测装置为压力传感器为例,储气装置上安装压力传感器用于检测储气装置内气压,当气压小于第一设定值时,电机带动气源泵工作,当储气装置内气压满足要求,如达到第二预设值时,气源泵停止工作。控制上具体可以采用PID控制,通过压力传感器采集的储气装置内气压形成闭环反馈,将气压稳定在设定范围内。根据需要,储气装置通过二级过滤器与用气设备连接,也就是储气装置内的气体经过二级过滤器到达用气设备。
在上述各3D打印设备的实施例中,请参阅图19,还包括加料装置9,加料装置9包括储料斗31、加料上盖22和阀门32,储料斗31的顶端具有开口,加料上盖22设置于储料斗31的顶端且用于打开或遮蔽开口,阀门32密封连接于储料斗31的底端以控制下料。也就是加料上盖22在储料斗31上部,阀门32在储料斗31下部。加料上盖22与储料斗31共同形成密闭空间,防止储料斗31内原料外溢或其内液料挥发。储料斗31主要用于储存3D打印设备所 需的原料,优选的其容积大于或等于如图11中工作箱7的容积。则储料斗31加满时,其内原料足够完成一个打印任务。在考虑空间占用等情况下,储料斗31的容积也可以小于工作箱7的容积,则完成一个打印任务过程中需再次加料。
进一步地,阀门32的下料口呈矩形,且矩形的长度与落料机构8的长度相等。如图19所示,阀门32的下料口呈矩形,矩形长度即下料口长度与图11中落料机构8的长度AB相等,阀门32打开时,储料斗31内的下部原料全部落到落料机构8内,使落料机构8的长度AB上全部落有原料,落料机构8内不再需要单独设置机构,将原料沿AB均匀填充。更进一步地,落料机构8的长度大于工作箱7的长度,从而保证铺料效果。具体的,为了储料斗31内的物料更好的下落,储料斗31下部有一定斜度,如储料斗31的下部逐渐向内倾斜,可以对其内部原料起到导向作用。
在上述各3D打印设备的实施例中,还包括液料系统1,请参阅图20,液料系统1包括清洗液桶、废液桶、树脂桶、第一电磁阀A1、第二电磁阀A2、第三电磁阀A3、第一液料泵(泵1)、第二液料泵(泵2)、清洗位3、压墨位、保护位,清洗液桶依次通过第一液料泵、第二电磁阀与清洗位3的清洗槽连接;树脂桶依次通过第二液料泵和第三电磁阀与打印机构10的打印头连接;压墨位和保护位的废液槽与废液桶连接,清洗位3的废液槽通过第一电磁阀与废液桶连接。液料系统1下部设置三个液料桶,分别为清洗液桶、废液桶、树脂桶,三个桶内分别盛装清洗剂、废液、树脂(3D打印机所喷射粘接剂)。清洗液桶与第一液料泵连接,第一液料泵与第二电磁阀连接。加清洗剂时,第二电磁阀打开、第一电磁阀关闭,第一液料泵将清洗液桶内清洗剂加入到清洗位3上清洗槽内,清洗槽上安装液位传感器,液位传感器检测到液位后第一液料泵停止工作。树脂桶与第二液料泵连接,第二液料泵与过滤器连接,过滤器与第三电磁阀连接,第三电磁阀通过管路与打印头连接。加入树脂时,第二液料泵与第三电磁阀同时打开,第二液料泵将树脂桶内液料加入打印头内部,供打印头打印使用。清洗位3、压墨位、保护位上废液槽通过管路连接进入废液桶,其中,清洗位3与废液桶 之间连接第一电磁阀。收集废液时,第二电磁阀关闭、第一电磁阀打开,废液由于重力作用,自流至废液桶,达到收集废液目的。
在上述各3D打印设备的实施例中,工作箱7包括固定于支撑框架4上的工作箱7外壳和能够相对工作箱7外壳滑动的活动底板,顶升机构19的底部与支撑框架4固定连接,顶端与工作箱7的活动底板固定连接,以带动互动底板沿垂直方向升降。具体的,工作箱7可以通过螺栓与支撑框架4固定连接,其活动底板与顶升机构19的上部门板固定连接,如通过螺钉或电磁铁固定,顶升门板上升或下降时,带动工作箱7的活动底板运动,实现3D打印设备高度方向运动。
在上述各3D打印设备的实施例中,还包括设置于支撑框架4外的外防护箱体20,外防护箱体20的顶部对应打印区的位置设置有上盖21以露出或封闭打印区。需要说明的是,打印区指工作箱7的位置,通过上盖21的设置,一方面可以通过将上盖21打开更好的观察打印过程,且在打印完成后,打开上盖21,人员站在3D设备正面,从工作箱7上部即可实现清箱并取出3D所打印产品。因此,不设置导轨或其他移动机构,工作箱7不移出设备即可进行清箱。

本申请还提供了一种供砂设备。
现有的3D打印设备都是工厂化设计,需要将庞大的供砂管路与3D打印设备连通,供砂管路固定设置,且占用较大空间,这很适合规模化生产,但是如果是做实验或者小规模或者在普通房间中设置的时候,就非常不方便。针对现有技术的不足,本申请提供一种供砂设备及3D打印设备,本申请公开的一个方面解决的一个技术问题是提供一种适用于实验或者小规模或者在普通房间中就可以工作的供砂设备。
本申请解决其技术问题所采用的一个技术方案是:
一种供砂设备,包括框架和设置在所述框架上的原料仓、输料装置、定量装置、混料装置、缓存装置,所述原料仓通过输料装置与定量装置连通,所述定量装置与所述混料装置连通,所述缓存装置与所述混料装置连通。
将供砂设备精简缩小至框架上,所有装置(除原料仓外)集成在一起,在较小空间中就完成混砂工作,并可以向3D打印设备进行输砂。整个装置(除原料仓外)都集成在框架上,实现在较小空间的布置,这套供砂设备一般都是设置在3D打印设备上方,便于物料从上至下流动,现在将这套供砂设置在3D打印设备侧面,减少整体设备的高度,实现小空间的布置。在其中一优选实施例中,原料仓设置于框架的外侧。这样有利于降低框架的安装高度。将原料仓中的颗粒物质,一般是砂粒,通过输料装置运输至定 量装置,定量装置称量设定量的颗粒物质,并且还有配套的液体称量装置,将相匹配的液体和称量好的颗粒物质转移至混料装置中,在混料装置中完成颗粒物质和液体的均匀混合,然后将混好的原料转移到缓存装置中,为增材制造设备提供原料。
优选的,所述定量装置设置在所述框架上部,且贯穿所述框架后,与所述框架中的混料装置连通,所述混料装置下部设置与所述混料装置连通的所述缓存装置,所述缓存装置下部设置所述原料仓,所述原料仓设置在所述框架下部。
将原料仓、输料装置、定量装置、混料装置、缓存装置都设置在框架上,从而实现方便整体移动,方便实验或者转移,而且空间最大化利用,原料仓一般盛装较多,从而设置在最下部,方便补料,然后通过输料装置将物料转移至定量装置,定量装置就设置在最上方,保证称料精度的同时,利于后续物料由上至下顺畅流动转移,中间的空间刚好容纳混料装置,实现物料均匀混匀。整体布局紧凑而且设计科学,最大化的利用空间,而且节约占用空间。
优选的,所述输料装置是负压吸料装置或者真空吸料装置或者搅轮输送装置中的至少一种。
利用输料装置实现物料由下至上的运输,为了提高效率而且形状受限较少,一般采用负压吸料或者真空吸料的形式转移,为了精简结构和重量,会选择搅轮输送的形式,总之选择合适的方式将物料由原料仓向上转移至定量装置。
优选的,还包括移动装置,所述移动装置设置在所述框架或者所述原料仓中至少一个的底部,且带动所述框架或者所述原料仓中至少一个移动。
为了更方便的移动,在所述框架和所述原料仓的下部可以设置移动装置,也就是可以设置轨道或者滑轮等方便移动的装置使得框架方便移动,或者方便原料仓进出框架。
优选的,所述混料装置包括桶体和搅拌装置,所述搅拌装置设置在所述桶体中,且所述桶体底面为向出料口倾斜的斜面,所述出料口与所述缓存装置连通。
混料装置的底面设置成向出料口倾斜,是为了方便物料向缓存装置流动,利于完全排空混好的物料,使得物料转移更迅速。
优选的,所述原料仓被分成至少两个开口向上的独立空间。
原料仓中存放的是旧砂和新砂,增材制造打印工作进行的时候,是将新砂和旧砂混合之后使用,可以节约成本,可以将新砂和旧砂混合之后存放在原料仓中,也可以将原料仓分成两个空间,直接分开存放新砂和旧砂,然后分别按照比例通过输料装置输送至定量装置,完成混匀工作。
优选的,所述原料仓的空间为下小上大的锥形空间,所述输料装置的一端设置在所述原料仓锥形空间底部。
为了配合输料装置,尽量完全的转移原料仓中的颗粒物质,原料仓的空间就设计成锥形,这样随着物料的减少,物料可以自动滑落,然后进入输料装置中,从而能实现尽量完全的物料转移。
优选的,所述框架包括架体、限位块,所述架体与所述原料仓相匹配位置为一侧开口状,且开口用于所述原料仓进出所述架体,所述开口相对一侧的所述架体上设置限位块,所述限位块与所述原料仓弹性接触,所述限位块由柔性弹性材料制成。
原料仓设计成推拉抽屉状,进出框架,因为原料仓重量较重,为了保护框架,设计限位块,限位块为弹性材料制成,从而在原料仓进出框架的时候,起到缓冲作用。
优选的,所述框架还包括导向轮,所述架体开口两侧设置所述导向轮,所述导向轮与所述原料仓接触,所述导向轮旋转方向与所述原料仓进出所述架体方向相匹配。
为了方便原料仓更方便的进出框架,设计了两侧的导向轮,从而起到导向作用,使得沉重的原料仓更快捷更安全的就位。
优选的,还包括液体定量装置,液体定量装置设置在所述混料装置一侧,所述液体定量装置与所述混料装置连通。
液体定量装置为混料装置提供液体,与原料仓中的颗粒物质混合。
一种3D打印设备,包括上述任意一项所述的供砂设备。
由上述技术方案可知,本申请公开的一个方面带来的一个有益效果是,整个供砂设备精简简单,而且便于移动,适合实验或者小规模3D打印设备。
