Description
技术领域
本发明涉及3D打印技术领域，具体涉及一种可掺杂复合材料颗粒的3D打印设备。
背景技术
熔融沉积制造(FDM) 3D打印机，属于快速成形技术领域的一种机器，它是以一种数字模型文件为基础，运用塑料等可粘合材料，通过逐层打印的方式来构造物体的技术。过去其常在模具制造、工业设计等领域被用于制造模型，主要工作过程为：将三维模型导入3D打印设备，设备会按照设置程序把产品一层层打印出来。打印出的产品，可以立即使用。作为一种增材制造技术，材料的性能至关重要，目前，多数打印机只能进行树脂材料的打印，材料成分过于单一，难以实现复合材料零部件性能的需求。
发明内容
针对上述技术的不足，本发明提供一种可掺杂复合材料颗粒的3D打印设备，可以有效地实现多种材料的复合零件的制备，并提高3D打印零件的性能。
为实现上述目的，本发明的技术方案是：3D打印机的各种配件；附加喷头部分，挤出机，电机，线材，颗粒材料储存箱，加热喷头，附加喷射装置，底板等。附加花洒喷射装置包括1个花洒喷头与（附加材料传送装置）。
附加材料传送装置包括材料输送管与鼓风机。
连接关系为：
进一步的，附加颗粒材料可根据需求进行选择。
进一步的，附加颗粒材料也可以复合多种材料。
进一步的，附加颗粒材料的喷洒量可根据输送量进行调节。
进一步的，在鼓风机前方可设置一个关闭舱门，以便更加准确控制风速。
进一步的，在材料储存箱下方同样设置一个关闭舱门，以便更加精准的控制材料传输。
进一步的，具体喷洒方向可根据调节喷头方向来进行调节。
本发明的优势处在于：
1. 实现了采用3D打印机进行材料混合打印，单一的颗粒材料难以实现不同工业上的需求，而本发明可将一种甚至多种的颗粒材料进行混合，以实现不同零件对材料性能个性化需求。
2. 通过改变输送颗粒材料的速度可以调整材料的复合量，以实现不同材料百分比。
3. 喷头的出头直径约为颗粒材料的4倍。
4. 喷射后的颗粒材料通过底部的收集器收集后，可以通过管道进行材料的再次利用，以实现绿色环保。
附图说明
图1是本发明的3D打印机装置示意图。
具体实施方案
图1是本发明的3D打印机装置的结构示意图，本发明的3D打印机设备包括：
挤出机电机1，颗粒材料储存箱2，挤出机3，底板4，鼓风机5，材料储存箱舱门6，鼓风机舱门7，开关8，加热喷头9，附加喷头10,电机11，电机12，线材13。
连接关系为：
挤出机电机1和电机11和电机12固定在上方框架上，线材13也放在上方，底板4固定在框架下方，附加喷头10和加热喷头9固定在一起，线材13和挤出机3固定于框架后方，附加颗粒材料从颗粒材料储存箱2中通过鼓风机5送入附加喷头10中。所示开关8在打印机下方。
所述材料储存箱舱门6和鼓风机舱门7设置在管道上。
所述底板9用于承载工作件。
所述鼓风机5放在地上。
所述颗粒材料储存箱2通过管道与附加喷头10固定在一起。
所述框架有玻璃格挡，以防止附加材料的浪费和以便于回收利用。
下面开始说明本3D打印机装置的工作流程：
通过三维制作软件将虚拟三维空间构建出具有三维数据的模型。
将3D模型储存成打印机所需的可直接取读的文件格式，并设计好打印路径。其次，通过3D打印机控制软件，把文件发送给打印机并控制3D打印机的参数，运动使其完成打印。
准备好上述过程后启动3D打印机，将3D打印材料装入材料储存箱中，首先打开鼓风机管道的舱门后启动鼓风机，按下开关，开关同时控制加热喷头和材料储存箱下方舱门的工作，开始工作后，打印机将会逐层打印，并通过横截面将所需打印的材料固定住，同时颗粒材料通过鼓风机的作用输送到附加喷射装置中，进行材料的复合，最终经过逐层叠加与复合完成打印，打印完成后，同时关闭鼓风机舱门，之后关闭鼓风机和材料输送箱下方闸门，完成打印，即可取出打印成功的物品。
本发明还可有其他多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
