Design and Simulation of the Bottom Forming Mechanism of Gable-box Filling Machine

目的针对目前屋顶盒灌装机底部成型机构设计的非合理性及工作不稳定等问题,对其进行结构设计。方法结合其工艺要求,设计出屋顶盒灌装机底部成型机构。对成型机构进行设计分析,计算中心杆的运动行程、摆杆张角范围及驱动力与纸盒反推力之间的关系。通过在Solid Works软件中建立三维模型,导入ADAMS软件仿真完成成型机构的动作过程。结果屋顶盒灌装机底部成型机构的运动轨迹合理,且摆杆张角在理论计算范围内,能够在运动时间内完成盒底成型。结论该设计不仅节省了空间,降低了成本,且提高了现有屋顶盒灌装机底部封口效率,具有较高的应用价值。

The work aims to design the structure of the bottom forming mechanism of gable-box filling machine with respect to its unreasonable design and unstable operating, etc. In combination with its technological requirements, the bottom forming mechanism of gable-box filling machine was designed. By analyzing the design of the bottom forming mechanism, the motion displacement of the center rod, the opening angle range of the swing rod and the relationship be- tween the driving force and the carton reverse thrust were calculated. A 3-D model was built based on SolidWorks and imported into ADAMS to simulate the action process of the forming mechanism. The simulation analysis results showed that the motion track of the bottom forming mechanism of gable-box filling machine was reasonable, and the opening an- gle of swing rod was within the theoretical calculation range. In such case, the bottom forming could be completed during one-time motion cycle. The design not only saves space and reduces costs, but also improves the bottom sealing efficiency of the existing gable-box filling machine, which has a high application value.
