曲面印刷机气动下料机构设计 摘要：曲面印刷机是一种用于回转型包装容器外表面彩色印刷的机电一体化设备，包括上下料机构和传动机构等等，我这次做的是曲面印刷机气动下料机构的设计。由可编程控器控制印刷机的运转、印刷机的急停和无杯不印等。我们所设计的曲面印刷机最多可以印六种色彩，也就是套印六色，例如印刷纸杯，最高速度可达每分钟300件，且印刷色彩较好，准确度高，自动化程度极高。它是一种凸版轮转胶印机，模把更换方便，可以广泛的应用于大批量、高效率的硬包装印刷。机械印刷不仅印速快，套印精度高， 而且能减轻工人的劳动强度[1]。 本课题设计的气动下料机构是全自动曲面印刷机的一台辅机，用于将印刷油墨干燥以后的杯子摞成卷，并按一定长度推至下料台。下料机气动系统的组成包括：执行元件气缸，控制元件电磁阀及辅助元件等。简述了气缸在结构中的安装方式及其所起的作用，并对关键零部件气缸进行了详细的分析设计。 运用Solid Works软件对叠杯装置、叠杯机架及下料台进行了设计，完成了三维实体建模、装配，并通过该软件导出二维装配图及其爆炸图。 关键字：曲面印刷机，气动下料机构设计，三维实体建模，Solid Works The Design of Pneumatic Cup Feeding Mechanism for Curved Surface Printing Machine Abstract：Surface presses a back transformation of the outer surface of the containers color printing electromechanical integration equipment, including rotary printing agencies, reel institutions, the upper and lower feeding mechanism and drive mechanism. By the programmable controller to control the operation of the printing press, press the emergency stop and no cup India. The machine up to overprint the six-color, maximum speed of 300 per minute, overlay accuracy, pattern reproducibility, high degree of automation. It is a letterpress and web offset printing press, the mold easy to replace, can be widely used in high-volume, high efficiency, rigid packaging and printing. Pneumatic feeding mechanism for the design of the subject is one auxiliary automatic surface presses for the printing ink after drying the cup stack of rolls, in accordance with a certain length to cutting Taiwan. Feeder pneumatic system components include: the actuator cylinder, and control components solenoid valves and auxiliary components. Cylinder installed in the structure and the role of the key parts cylinder carried out a detailed analysis and design. Solid Works software design, cup stacking device, cup stacking rack and cutting completed a three-dimensional solid modeling, assembly, and export 2D assembly drawings and exploded diagram of the software.
