喷码机的单极性和双极性高压偏转板对电场分布的影响

The Influence of the Monopole and the Bipolar High Pressure Deflection Plate on the Electric Field Distribution

摘要: 喷码机的高压偏转板是喷码机喷头中的一个关键组成部分。高压偏转板通电之后，两极板之间会产生一定的高压电场。墨滴在充电极充上电，进入高压偏转板，在偏转电场作用下发生偏转。改变墨滴的带电量或者改变高压偏转板间的电场强度，可以改变带电墨滴的偏转位移量。偏转板间电压的极性对墨滴的偏转位移量是有一定影响的。本文研究分别在单极性高压偏转板和双极性高压偏转板条件下，带电墨滴在进入偏转板前、以及离开偏转板后的电场分布情况。同时研究充电极电压对进入偏转板前的场强分布的影响。

Abstract: The high pressure deflection plate of the inkjet printer is a key part of the inkjet printer nozzle. After the high voltage deflector plate is electrified, there will be a certain high voltage electric field between the two plates. The droplet is charged at the charging pole and enters the high voltage deflector, deflecting under the deflection electric field. Changing the electric charge of the droplet or changing the electric field intensity between the high voltage deflector can change the deflection displacement of charged droplet. The polarity of the voltage between the deflection plates has a certain effect on the deflection displacement of the droplets. Under the condition of unipolar high pressure deflection plate and bipolar high pressure deflection plate, the electric field distribution of charged ink drops before entering the deflection plate and leaving the deflection plate respectively. Meanwhile, the influence of charging pole voltage on the field strength distribution before entering the deflection plate is also studied.
