滾筒式寬幅數(shù)字噴印設備的結構設計

摘    要

隨著經(jīng)濟的不斷向前發(fā)展，國內市場上對于高品質影像輸出、彩色渲染圖輸出、展覽廣告設計、地理信息系統(tǒng)(GIS)圖輸出、大幅面海報打印、戶外看板制作等業(yè)務的需求越來越多。這就迫使廣告業(yè)和印刷業(yè)對大幅面彩色噴繪機有著很大的需求?，F(xiàn)階段，國內在大幅面幅彩色噴繪機的開發(fā)方面還處于起步階段。市場上國內產(chǎn)品不多，這正是研發(fā)質優(yōu)價廉的大幅面幅彩色噴繪機產(chǎn)品的最佳時機。
本論文主要針對寬幅數(shù)字噴印設備的結構分析，完成噴印設備橫向和縱向兩個方向的傳動設計。噴印小車由動態(tài)性能好、定位精度高的無刷直流伺服電機驅動，經(jīng)過一組齒輪減速器，并由可以遠距離平穩(wěn)傳動的同步齒形帶將電機轉動變成橫向移動，讓小車在導軌上運動。紙張由步進電機驅動，經(jīng)過一組減速齒輪帶動滾筒轉過，從而完成紙張的縱向移動。同步齒形帶的選擇計算，收紙機構和輸紙機構選用同一型號電機，通過齒輪不同的減速比，讓直徑不同的兩個滾筒達到同步運動是本設計的重點。

關鍵詞：寬幅噴印，同步齒形帶，滾筒,步進電機

 

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
