摘要
提出了一种同步齿形带分瓶装置,分析了连续定数分瓶的工作原理,设计了定数分瓶的控制方案;利用SolidWorks软件对执行机构进行动力学分析,得到了灌装瓶在分瓶过程中的速度时间图和灌装瓶与分瓶同步带接触力随时间变化图;利用运动学分析结果在ANSYS建模进行了同步带瞬态动力学分析,得到同步带变形分布图、应力分布图,其中最大变形为2.083 96 mm,最大应力为36.3814 MPa,均满足设计要求,能够实现稳定、连续高效分瓶,研究表明该技术具有较好的应用前景。
The synchronous belt device is designed for grouping bottles in this paper; the working principle is analyzed regarding continuous bottle-grouping with a certain number and the control scheme is presented. Based on the dynamic analysis with Solid Works, two charts are obtained, which reflect the time history of the transverse velocity and contact force respectively. Moreover, the results are used to analyze the transient dynamics of the synchronous belt with ANSYS.Finally the distribution diagrams of deformation and stress of the synchronous belt are obtained, which reveal that the maximum deformation is 2.083396 mm and the maximum stress is 36.3814 MPa. According to the results, it is obvious that the synchronous belt meets the design requirements and it can be used to group bottles stably and efficiently. Studies have shown that the technology has good application prospect.
