中文摘要:
      目的 分析枕式包装机横封旋转轴的运动特点和规律,提出一种基于PLC、伺服放大器和伺服电机的电子凸轮系统,用于代替现有凸轮机械结构。方法 研究枕式包装机横封轴的机械结构和运动轨迹,采用物理建模法建立运动模型,重点论述电子凸轮的运动过程、模型建立和关键参数的求取。结果 与传统高阶次数学模型相比,该模型简单且易于编程实现,同时提高了横封旋转轴运动过程中不同时间点速度的可控性,实现了柔性变速旋转。结论 解决了因机械凸轮长期磨损造成精度损失而导致裁剪效果、包装精度变差等问题,从而提高了包装精度,增加了横封切刀的寿命,减小了设备机械振动。
英文摘要:
      The work aims to analyze the movement characteristics and rules of the transverse sealing rotation shaft of pillow packer, and put forward an electronic cam system based on PLC, servo amplifier and servo motor, which is used to replace the existing cam mechanical structure. The mechanical structure and motion track of the transverse sealing shaft of the pillow packer were studied, and the motion model was established in the physical modeling method. The motion process, the model establishment and solution to key parameters of the electronic cam were emphatically discussed. Compared with the traditional high order sub mathematical model, the model was simple and easy to program. Meanwhile, it improved the controllability of the speed at different time points in the course of motion of the transverse sealing rotation shaft, and realized the flexible variable speed rotation. The model solves the problems of worsened cutting effect and packaging accuracy due to the loss of accuracy caused by the long-term wear of the mechanical cam. Thus, the packaging accuracy is improved, the service life of the transverse sealing cutter is increased, and the mechanical vibration of the equipment is reduced.
