裁纸机结构设计及运动仿真分析 摘要 裁纸机是装订过程中成书不可缺少的辅助设备，属印刷机械设备，它可将纸张根据要求尺寸和规格进行裁断、分切。 本文重点对切纸机的结构作了论述。本文以QZ-203切纸机为研究对象，QZ-203切纸机工作由液压和机械驱动。压纸器用液压力压紧，压力可视裁切需要任意调节，裁切是机械齿轮传动，具有较高的裁切效率。它采用继电器、接触器控制方式，其控制系统较为落后，故用可编程控制器对其控制过程加以适当的改造，以提高其效率及安全性。 切纸刀的裁切运动是切纸操作中一个重要的环节，切纸刀通过电机带动飞轮再通过齿轮的二级变速来作上下斜切运动，从而大大减小了切纸刀所受到的阻力。这其中通过计算选择了传动带的带型、齿轮、轴、轴承的型号。送纸器运动系统中主要计算送纸器前进、后退的速度，压纸器运动系统的设计主要是液压运动系统的设计，电气系统的控制主要是电机的控制，设计好顺序控制就能使整个系统运作起来，接下来就可以用可编程控制器来改造电气控制系统。可编程控制器控制系统中PLC型号的选择和梯形图的编译很重要。 本论文所研究的切纸机的优点是它能把机器的启动、送纸器的运动和位置控制、压纸器的控制和切纸刀的运动用可编程控制器很好的进行控制，从而形成一个完整的控制系统，它也有经济、实用的特点，特别适合这种中小机械的生产。生产自动化是今后工业发展的方向，可编程控制器控制系统、单片机控制系统、计算机控制系统以及集散控制系统运用到生产中将大大提高生产效率。 关键词　切纸机；压纸器；液压；齿轮；可编程控制器 Cutting Knife Structure and Design of PLC Control System Abstract Paper cutter is a book binding machine,which belongs to printing equipment. It cuts paper by its dimension. It is very important in book binding. This article focused on the structure of the cutter are discussed. This paper cutter for the QZ-203 study, QZ-203 cutter work driven by the hydraulic and mechanical. Paper used in liquid pressure compacting pressure, the pressure of cutting the need visualization of arbitrary regulation, gear cutting machinery, cutting efficiency higher. It uses relays, contactor control, the control system is lagging behind, the programmable controller used to control the process of its transformation to be appropriate in order to improve their efficiency and security. Paper cutting knife cutting operation, movement is an important aspect of knife Cutting through the flywheel drive motor through the gears up and down for two variable-speed oblique movement, which greatly reduces the cutting resistance by a knife . This chosen by calculating the bands belt, gears, shafts, bearings models. Movement System feeder feeder main computing forward and backward speed, pressure moving paper system is the design of hydraulic motion systems, electrical control system is mainly motor control, sequential control can be designed so that the operat
