平面模切机的模切过程优化

针对印后包装设备模切机在高低速模切时的不同要求及模切速度快速变速规划的需要，优化模切过程。首先，分析伺服驱动模切凸轮机构的运动过程；然后，优化模切驱动电机的整体运动规划，实现不同模切节拍下，切刀模切瞬间的速度不变，使下压阶段和提升阶段的电机最大扭矩保持平衡；随后，进一步对模切加减速段进行优化，设计非等腰三角形规划，以高效发挥模切驱动电机的性能。该控制策略能提高切刀寿命，提升模切整体效率。

Optimization of Die-Cutting Process of Plane Die-Cutting Machine

For the die-cutting machine of post-press packaging equipment, according to the different requirements of high and low-speed die-cutting and the need for rapid variable-speed planning of die-cutting speed, the optimization strategy of the die-cutting process was studied. First, the motion process of the servo-driven die-cutting cam mechanism was analyzed. Then, the overall motion planning of the die-cutting drive motor was optimized to realize that under different die-cutting beats, the speed of the cutter at the moment of die-cutting remained unchanged, and the maximum torque of the motor was balanced in the pressing stage and the lifting stage. subsequently, the die-cutting acceleration and deceleration phase was further optimized, and a non-isosceles triangle plan was designed, which efficiently played the performance of the die-cutting drive motor. This control strategy can improve the service life of the cutter and the overall efficiency of die cutting.
