制袋机的关键技术在于如何保证切断长度的精度控制及生产速度的提高。早期的制袋机均采用曲柄摆杆、扇形齿轮和超越离合器机构,由曲柄机械调整袋长,由微电机修正摇杆扇面齿轮面上的偏心位置进行定位修正以达到定位控制目的,但此机构无论是制造还是进行袋长设置都很麻烦,且运行速度慢,定长切割精度不高。随着交直流伺服技术的提高,制袋机的生产速度及产品定长精度两个问题 The key technology of bag making machine lies in how to ensure the accuracy of cut length control and the increase of production speed. Early bag-making machines are used crank swing rod, sector gear and clutch mechanism, the length of the bag by the crank mechanical adjustment by the micro-motor rocker surface modification eccentric position correction to achieve positioning control purposes, but this mechanism Whether it is made or bag length set are very troublesome, and slow running, fixed-length cutting accuracy is not high. With the improvement of AC-DC servo technology, bagging machine production speed and product fixed-length accuracy of two issues
