Abstract : this paper presents the principle of paper - delivering device theoretically , and the new concept of “ non build - margin paper - delivering ” is p ut forward , which has been proved to be fully feasible , in comparision with the ub iquitously incorrect concept of “ giveing larger build - margin while processing la rge workpiece and less one to small workpiece ” 文摘:着重阐述了分层实体制造激光快速成型机走纸机构的原理,并提出在零件加工过程中“无搭边送纸”的新概念,经过实践证明是完全可行的。
The printer at present is used extensively in many fields . thus the higher request is put on the stylus printer quality and print speed which lies on the driving electric machinery of printer fast and placidly driving the movement of printer ’ s pin and the fast startup and stop and exact orientation of the driving paper electric machinery 打印机的应用非常普遍,同时人们对打印质量和速度的要求也越来越高,其中针式打印机的打印质量和速度主要依赖于打印机的驱动电机带动打印头运动的快速平稳以及走纸电机的启停快速、定位准确。
