Description

梯度供粉混料装置
技术领域
本发明涉及一种梯度供粉混料装置，属于增材制造领域。
背景技术
梯度材料是指两种或两种以上性能不同的材料，通过改变这些材料的组成和结构，使其无界面地逐渐变化或突然变化而形成的材料，用3D打印方法进行可以进行梯度材料等多材料烧结加工的试验研究，在梯度材料3D打印试验过程中，需要将按两种或两种以上材料按配比的比例均匀混合，由铺粉小车将均匀混合后的材料均匀铺满成型缸上表面，然后由激光进行烧结加工。在先前申请的带有梯度供粉***的3D打印机(CN109047765A)中，介绍了一种可实现材料水平截面连续梯度变化的梯度供粉***，该梯度供粉***采用了一种旋转混料装置，该装置需要专门电机或驱动元件驱动，复杂且占用空间比较大，设计布置不便，力求寻找一种简洁但又可满足混料功能要求的混料装置。
发明内容
本发明的目的在于提供一种梯度供粉混料装置，该梯度供粉混料装置在无动力输入、无需转动搅拌的情况下，可实现两种或两种以上材料按要求混合，可防止材料沿轴向方向(Y轴方向)的混合串动。
本发明的上述目的是这样实现的：提供一种梯度供粉混料装置，该混料装置由落料槽、落料槽内隔柱组成，落料槽内隔柱安装在落料槽内，沿高度方向一层层错位排列，沿X轴方向一个个并列排列，沿高度方向层数不少于两层，沿高度方向排列的层距大于落料槽内隔柱截面半径，沿X轴方向每排截面中心间距大于截面直径，但小于2倍截面直径，沿X轴方向每排排列数量以布满落料槽下口宽度为准，最终保证粉料可以由上至下比较顺利落下。
所述的梯度供粉混料装置，在该混料装置的落料槽内还安装有落料槽内隔板，该落料槽内隔板沿Y轴以不少于两排、间隔均匀地布置，落料槽内隔柱均穿过落料槽内隔板。
所述的梯度供粉混料装置的落料槽内隔板，其厚度不小于0.1毫米，不大于0.5毫米。
本发明的梯度供粉混料装置具有如下有益的效果：
本发明的目的在于提供一种梯度供粉混料装置，该梯度供粉混料装置通过在落料槽内错位布置的多层内隔柱，使粉料从上至下通过每层内隔柱间的间隙，形成迷宫式路径，使粉料在无动力输入、无需旋转搅拌的情况下，实现材料的混合，通过在落料槽内安装落料槽内隔板，可防止材料轴向(Y轴方向)的混合串动。
