滾筒式寬幅數(shù)字噴印設(shè)備的結(jié)構(gòu)設(shè)計(jì)

摘    要

隨著經(jīng)濟(jì)的不斷向前發(fā)展，國(guó)內(nèi)市場(chǎng)上對(duì)于高品質(zhì)影像輸出、彩色渲染圖輸出、展覽廣告設(shè)計(jì)、地理信息系統(tǒng)(GIS)圖輸出、大幅面海報(bào)打印、戶外看板制作等業(yè)務(wù)的需求越來(lái)越多。這就迫使廣告業(yè)和印刷業(yè)對(duì)大幅面彩色噴繪機(jī)有著很大的需求?，F(xiàn)階段，國(guó)內(nèi)在大幅面幅彩色噴繪機(jī)的開發(fā)方面還處于起步階段。市場(chǎng)上國(guó)內(nèi)產(chǎn)品不多，這正是研發(fā)質(zhì)優(yōu)價(jià)廉的大幅面幅彩色噴繪機(jī)產(chǎn)品的最佳時(shí)機(jī)。
本論文主要針對(duì)寬幅數(shù)字噴印設(shè)備的結(jié)構(gòu)分析，完成噴印設(shè)備橫向和縱向兩個(gè)方向的傳動(dòng)設(shè)計(jì)。噴印小車由動(dòng)態(tài)性能好、定位精度高的無(wú)刷直流伺服電機(jī)驅(qū)動(dòng)，經(jīng)過(guò)一組齒輪減速器，并由可以遠(yuǎn)距離平穩(wěn)傳動(dòng)的同步齒形帶將電機(jī)轉(zhuǎn)動(dòng)變成橫向移動(dòng)，讓小車在導(dǎo)軌上運(yùn)動(dòng)。紙張由步進(jìn)電機(jī)驅(qū)動(dòng)，經(jīng)過(guò)一組減速齒輪帶動(dòng)滾筒轉(zhuǎn)過(guò)，從而完成紙張的縱向移動(dòng)。同步齒形帶的選擇計(jì)算，收紙機(jī)構(gòu)和輸紙機(jī)構(gòu)選用同一型號(hào)電機(jī)，通過(guò)齒輪不同的減速比，讓直徑不同的兩個(gè)滾筒達(dá)到同步運(yùn)動(dòng)是本設(shè)計(jì)的重點(diǎn)。

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
