滚筒式宽幅数字喷印设备的结构设计

摘    要

随着经济的不断向前发展，国内市场上对于高品质影像输出、彩色渲染图输出、展览广告设计、地理信息系统(GIS)图输出、大幅面海报打印、户外看板制作等业务的需求越来越多。这就迫使广告业和印刷业对大幅面彩色喷绘机有着很大的需求。现阶段，国内在大幅面幅彩色喷绘机的开发方面还处于起步阶段。市场上国内产品不多，这正是研发质优价廉的大幅面幅彩色喷绘机产品的最佳时机。
本论文主要针对宽幅数字喷印设备的结构分析，完成喷印设备横向和纵向两个方向的传动设计。喷印小车由动态性能好、定位精度高的无刷直流伺服电机驱动，经过一组齿轮减速器，并由可以远距离平稳传动的同步齿形带将电机转动变成横向移动，让小车在导轨上运动。纸张由步进电机驱动，经过一组减速齿轮带动滚筒转过，从而完成纸张的纵向移动。同步齿形带的选择计算，收纸机构和输纸机构选用同一型号电机，通过齿轮不同的减速比，让直径不同的两个滚筒达到同步运动是本设计的重点。

ABSTRACT

With the development of economy, the business demand of high quality image, color romance picture, GIS image, high wide poster printing, open show board and so on is increasing in domestic market, which pushes the advertisement industry and printing industry requires more on the high wide color plotter. Nowadays, there search of high wide color plotters in my country is at the beginning step. Only little domestic products are in the market. So it is the optimal chance for us to develop the low-cost and high-quality products.
This paper wide digital jet printing equipment for the structure, completed jet printing equipment horizontal and vertical design of the two directions of transmission. Jet printing car from a good dynamic performance, high-precision positioning of the brushless DC servo motor drive, after a group of gear reducer, and the distance can be a smooth transmission of the timing belt will turn into a horizontal movement motor, the car Guides on the campaign. Paper by the stepper motor driver, after a slow roller gear driven passed, thus completing the paper longitudinal movement. Timing with the choice of terms, to paper and feeding agencies choose the same motor, through different gear reduction ratio, so that the diameter of two different drum achieve synchronous movement is the focus of this design.

Key words：Wide jet printing，Timing belt，tolling drum，magnetic stepping
