摘　　要：为了研究带状材料的复转、分切等生产工艺中的新型张力控制系统,对带状材料的复转、分切等生产工艺中影响张力的因素进行分析,建立基于带状材料放料圈数的张力控制数学模型,提出了便于对张力进行自动控制和检测的新模式。通过测量放料辊上的带材圈数和计算它的变化率,可以控制制动器的电流,从而控制了分切机的收卷张力。以单片机为核心的张力控制和收料电机控制系统能够达到张力恒定。实际应用结果表明,基于87C196KB单片机的新型张力控制系统运行稳定,生产效率提高了27.5%,达到预期的效果。The factor that influence the tensility of the dividing technology was analyzed,the mathematics model controlling tensility that based on the number of circle for the discharging roller was established,the new mode that tensility was measured and controlled easily was put forward.Measuring the circle number for the discharging roller and computing its differential can control the excitation electric current of arrester,and then the furling tensility of dividing machine was controlled.Based on the model of controlling tensility,the system that control tensility and control furling electromotor was designed with microcontroller.Practical application shows that the controlling model and the system is valid.
