摘　　要：圆盘切刀广泛应用于造纸、印刷以及软包装等领域,具有刃口坚韧、使用寿命长、分切效率较高等优点。然而为了满足现代分切技术中的高精度、高分切端面质量要求,实时调整圆盘切刀与切材的相对角度是一种非常有效的手段。研究设计出一套高精度的角度实时调整系统,基于光电检测原理,设计出圆盘角度检测系统作为整个系统的传感机构;控制原理由PLC控制与伺服电机控制相结合,并且采用闭环控制,具有精度高、灵敏性好以及可靠性高等优点。设计的角度实时闭环调整系统在新望XW-221C全自动分条机上得到应用,在全速生产时,调节精度精度可达±2×10-2rad,实际生产效果达到了预期希望,对其他分切技术也具有较大的借鉴价值。Discal cutter is widely used in paper industry, printing industry and flexible package industry because the fact that it has many special advantages, such as sharp and durable cutting edge, long service life and high efficiency, etc. However, to satisfy high precision and quality of modern slitting technology, it is an effective method that angle real-time adjustment system is applied in discal cutting. In this study, a high-precision real-time angle adjustment system, first of all, an angle detecting system is designed as sensor body in discal cutting based on photoelectric detection technology. Secondly, a real-time and closed-loop angle adjustment equipment is carried out on the basis of the combination of PLC and servo motor control technology, this equipment is with high accuracy, high sensitivity and reliability. Eventually, the angle real-time and closed-loop adjustment system has been successfully applied on Xinwang full-automatic workbench （XW-221C）, and the experimental result shows that there is only ＆#177; 2 ＆#215; 10-2rad angle error at full capacity. In addition, this adjustment system can also provide reference significance for other cutting technology.
