摘要
提出了一种新型3D打印废料回收及混料装置。首先,进行了总体方案的设计,采用模块化方案,确定该装置主要由破碎机构、混料机构以及熔融挤出机构组成;其次,综合考虑装置整体尺寸及热塑性塑料特性,对以上3部分分别进行了结构设计及部件选取,并对主要参数进行了计算;最后,使用Hypermesh软件对主要部件动刀架、定刀架及其刀具进行了有限元分析,验证了动刀、定刀均符合强度要求,进而验证了该装置运行过程的可靠性及稳定性。
A new 3 D printing waste recycling and mixing device was proposed. Firstly, the overall scheme was designed, and the modular scheme was adopted to determine that the device was mainly composed of a crushing mechanism, a mixing mechanism and a melt extrusion mechanism. Secondly, considering the overall size of the device and the characteristics of the thermoplastic, the structural design and component selection were carried out for the three above arts separately, and the main parameters were calculated. Finally, the finite element analysis of the main tool moving tool holder, fixed tool holder and its tool was carried out using Hypermesh software, which verified that the moving knife and the fixed knife met the strength requirements. In turn, the reliability and stability of the device operation process were verified.
