基于SolidWorks的塑料瓶盖加热仓设计及流场仿真

Design and flow simulation of the heat container for plastic bottle caps based on SolidWorks

针对塑料瓶盖在低温环境下脆性增加,导致生产过程中出现连接桥断裂、高歪盖等现象的问题,开展了塑料瓶盖加热仓的设计与应用研究,对国内目前的瓶盖加热方法进行了分析归纳,提出了一种采用热风机进行在线加热的瓶盖加热仓装置。利用流体仿真软件Solid Works Flow Simulation建立了加热仓的流体模型,得到了热空气温度分布图和流场分布图。仿真结果表明,加热仓设计合理、温度分布均匀,无加热死角。研究结果表明,该加热仓设计简单合理,可显著减少生产中由于瓶盖引起的饮料质量问题,具有很好的经济效益。

Aiming at the problem that plastic bottle caps＇ brittleness will be increased in low temperature environment, which leads to the broken bridge and twisting cap in production, the design and application of the heat container for plastic bottle caps were researched. A heat device by air heater was later on presented after an exploration of cap-heating methods. With the assistance of CFD software SolidWorks flow simulation, the heat container fluid model was established and based on which the distributions of the temperature field and streamline were obtained. Furthermore, the simulation results indicate that the heat container is reasonably designed with uniform temperature distribution. The results indicate that the design of the heat container is concise and reasonable, and it can significantly reduce the quality problem caused by caps in production and has very good economic benefits.
