随着包装行业的迅猛发展,瓦楞纸板生产线的生产效率逐年提高,主要体现在瓦楞纸板生产线后端的电脑横切机速度的大幅提高。电脑横切机的控制部分需满足精准的裁切长度的同时还要满足很高的裁切速度。其难点在于纸板处于高速运动状态,切刀的动态控制需极高的运算速度和极高的跟踪性能。变频器的控制无法达到高的裁切速度(40～80m/min),裁切误差也随速度的提高而越来越大,PLC对脉冲的反馈速度也无法满足裁切精度的要求。运动
With the rapid development of the packaging industry, the production efficiency of corrugated cardboard production lines has been increasing year by year, which is mainly reflected in the substantial increase in the speed of computer crosscutters at the back end of corrugated cardboard production lines. Computer cross-cutting machine control part to meet the precise cutting length but also to meet the high cutting speed. The difficulty is that the cardboard is in high-speed movement, the dynamic control of the cutter requires extremely high computing speed and high tracking performance. Inverter control can not achieve high cutting speed (40 ~ 80m / min), cutting error is also increasing with the increasing speed, PLC pulse feedback speed can not meet the cutting accuracy requirements. movement
