摘  要

薄刀分纸机机是一种通用的设备，应用范围非常广泛，薄刀分纸机机在工业生产中占重要的地位。随着社会的进步和科学的发展，造纸业、印刷业对薄刀分纸机机提出了更高要求。该文针对国内薄刀分纸机的缺陷，将横向剪分与纵向剪分分开，从纵向滚刀的安装方式和横刀的剪分时间控制为突破口，设计了一种可以纵横双向剪分、可以按照商家要求剪分可变尺寸纸张的薄刀分纸机机。用于从事商标、名片和各种印刷制品的剪分工作。该薄刀分纸机机结构简单、动作简洁快速，全套工作流程由PLC控制，具有剪分质量高，生产效率高的优点。整个设计过程详细论证了其原理方案的可行性和机构的合理性，结构设计全用先进的CATIA软件造型、装配，真实地展示了整个系统的结构尺寸和工作原理。在设计过程中，通过对实际应用产品的设计，增强了对所学专业知识的掌握，提高了对设计思想理念的理解和实际运用能力，同时培养了自己独立完成设计任务的能力，认识到了严谨的工作态度对设计产品质量的重要作用。当然，在本设计中，仍然存在许多不完善的地方，在以后的设计中会加以借鉴，逐步改进。

Abstract
Paper's cutting machine is a kind of general used equipments, its application is very extensive, almost each printing business enterprises have installed paper cutting machine, the paper cutting machine has an important position in printing machine product. Along with the progress of the society and the development of science, there will be a higher request to the paper in paper making industry and print. This text aim at the limitation that the local paper cutting machine can cut only one side and only fixed dimension, separating across cutting and vertical cutting, breaking from the installation of the vertical hob and the time control of the across hob .Design a kind of cutting machine which can cut from both across and vertical and can cut alterable size according to the request of the merchant. Used in the work of cutting label, business card and many kinds of presswork. The structure of this kind of cutting machine is very simple and its motion is prompt. The complete workflow is controlled by the PLC system, having the advantage of high quality of cutting and working with efficiency. The whole design process demonstrates the feasibility of this theory and the rationality of the institution. All of the structure design use the CATIA software to shape and assemble, displaying the size of the structure and work principle of the whole system really. During the design, through the design of the actual apply product, enhance the comprehension of specialty acknowledge and improve the comprehension and actual apply ability of the design idea. At the same time ,develop the ability of completing design mission oneself and understand the important effect of the religious working attitude to design the quality of the product .Certainly, there must be some places not perfect in this design .I will use them for reference in the later design to improve greatly.
