摘要

中文摘要 打印机卡纸和噪声一直是困扰打印机厂商的技术难题,相关理论研究也受到了国内外学者的关注。然而,本项目前期研究发现,与国外品牌相比,国产打印机还存在纸尾脏、褶皱等问题,这些问题主要发生在打印机内部转印后、定影前的过渡阶段以及定影过程中,这段纸路空间大且环境复杂。本项目以转印到定影段为研究对象,综合考虑机内热气流、摩擦及撞击等因素的影响,研究纸张在转印辊对夹持作用下的运动特性,分析纸张在定影辊对作用下的整体变形和内部变形与压力、温度及传送速度之间的关系,探索纸张在软弹材质辊作用下的传送机理;研究转印辊对与定影辊对之间的速度及位置关系对纸张传送的影响,并通过实验测试、记录和分析纸张传送过程中的相关数据,进一步完善理论模型。应用以上理论成果优化设计送纸机构,并设计系列实验验证成果。本项目可为打印机送纸机构的优化设计提供理论指导,为解决机内卡纸、纸尾脏、褶皱和噪声等实际问题提供思路和理论支撑。
英文摘要 Paper jam and noise are the main technical problems troubled printer manufactures, the relevant theoretical research also got extensive attention by experts at home and abroad. However, our previous studies found that compared with foreign brands, domestic printers also exist problems such as dirty paper tail and paper wrinkle. These problems mainly occured in the transition stage inside the printer after transfer and before fuser and in fuser process, and this space is large and complex. This project takes this route as the research object and intends to carry the following contents: researching the paper motion characteristics under the action of transfer rollers considering the influence of heat flow, friction and impact, and analyzing the whole deformation and internal deformation of paper, and the relationship between paper deformation and pressure, temperature and transmission speed under the action of fuser rollers, in order to explore the principle of paper transmission under the action of soft elastic rollers; researching the influence of the speed and position relationships between transfer rollers and fuser rollers on paper transmission. And then, we test, record and analyze the relevant data during paper transfer to further improve the theoretical model.Finally, using these theoretical results to optimize the design of paper feeding mechanism, and design a series of experiments to verify these results. This project will provide theoretical guidance for optimization design of paper feeding mechanism, and provide ideas and theoretical support for solving paper jam, dirty paper tail, paper wrinkle and noise problems.
