摘 要
分切压痕机是生产包装纸箱所用瓦楞纸生产线中重要的设备，其产品的质量主要是由设备控制系统的优良程度所决定的。本文将对PLC对分切压痕机系统控制做一定的阐述。
本课题是针对在生产及生活中用量极大的纸产品——瓦楞纸，利用现代的PLC控制技术对它的工作流程进行控制，并以组态仿真来模拟其全部生产过程。整个工艺流程分为开卷、压痕、涂胶、粘合、烘干、分切和磨刀7部分。针对整个生产过程所需要的输入和输出端口较多，计算比较复杂等等的特点，本设计采用了西门子PLC S7-300对分切压痕机的设计。并使用组态软件对其程序进行监控和管理，更好的实现了对现场实时监测与控制，并且直观，生动的体现了分切压痕机的整个工艺流程。
传统的制作方式耗电多、可靠性差、寿命短、运行速度慢，若使用PLC对分切压痕机进行控制则能更好的规范制作的产品，也可以简化操作并提高工作效率。使瓦楞纸的生产更适应现代快节奏的生活。

Abstract
Cutting and creasing machine is important in the manufacture corrugated paper production line equipment, the quality of its products is mainly determined by the equipment control system of good or bad. This paper will do some discussion about PLC control cutting and creasing machine system.
This task is great for production and life--corrugated paper products, it process with PLC control technology, and simulation to simulate all of it’s about production process by configuration software. Whole process include uncoiling, indentation, gluing, adhesion, drying, cutting and sharpen part 7. As the entire production process needs more input and output ports, calculation is more complex, and more features, this design uses a Siemens PLC S7-300 to design cutting and creasing machine. And use the configuration software for monitoring and management real time, and intuitive, vivid embodies the cutting and creasing machine process flow.
Traditional way of making should waste more energy consumption, poor reliability, shorter work time, slow running speed, if using PLC to control the cutting and creasing machine should better for specification product, can streamline operations and improve productivity. It will making corrugated paper production m
