复卷机的电气传动系统设计 摘要 在整个造纸工艺过程中，大多数卷纸机卷得的纸卷存在松软现象, 内部一般会有破损情况, 边缘两侧不整齐, 纸幅宽度不一等原因不能直接使用于印刷机和纸加工等设备，需要复卷机对纸卷经过再次复卷，使之能够符合纸加工和印刷机的要求。随着现代社会对纸机自动化要求的提高, 产品质量的提高, 复卷机的产能也必须得到提高。而且，纸机的速度随着科技发展越来越高，相应相配套的复卷机也必然要提高速度和控制精度，控制系统自动化程度也得较高，所以，对于复卷机电气传动系统的设计，对提高复卷机的整体性能是有利的。本课题对高速双底辊复卷机的电气传动系统进行了设计。复卷机自动控制系统分为两部分，复卷机控制系统和电气传动系统。复卷机控制系统控制的对象是复卷机本体设备和复卷机外部设备，本文主要通过复卷机性能要求和工艺流程来设计复卷机的电气传动系统，以及根据传动系统的控制原理对传动电机与变频器进行选型。 关键词：复卷机；变频调速；张力控制 Abstract In the paper making process, due to the volume of the drum roll is relatively soft, the interior may be damaged, side edges.Edge irregular, web width and other reasons can not or printer paper handling and other equipment needed to roll rewinding directly. Rolling again, comeback roll processing and printing presses to meet the processing needs. With modern paper machines increased automation, improved product quality, productivity winder can also put forward higher requirements. In addition, increasing the speed of the machine, its match winders are bound to have a very high speed and control high degree of precision and automation control system, therefore, in the design of electric winder drive systems, helping improve network cylinder machine overall performance. High-speed drum winder automatic control system design issues. Rewinder automatic control system is divided into control systems and variable speed control system in two parts, the winding machine. Winder control Siemens S7-400PLC, Panasonic transmission system system. In the device and the in external device control coiler winding machine body, operating winding equipment, production data, production parameters set winder, browsing history data Winder winding machine control system from control system to complete . Transmitted mainly through open-book machine, after the end of the front bottom roller motor, roller motor frequency control, so as to keep constant tension of winder control, control of the roll tightness. Structure and function of the control system of a paper
