Embodiment 1

[0035] This embodiment discloses as figure 1 Shown is a flow chart of an improved ink droplet-charging small-character jet printing method. This embodiment is mainly based on two physical laws: the law of universal gravitation and the deflection of charged particles in an electric field. Before this invention, the nozzles of small character inkjet printers were mainly printed one by one. It may cause the distance between adjacent ink drops to be too large as the expected value, making it difficult to adjust the software and hardware. In order to avoid the position of the ink drop falling beyond the expected value as much as possible. We reorder the drop order for the ink droplets. Make the mutual interference between the ink droplets small, so that the ink droplet landing position meets the expectation.

[0036] The method disclosed in this embodiment based on the improved ink droplet charging small character jet printing method includes the following steps:

Embodiment 2

[0048]This embodiment mainly relies on the rearrangement of the charged ink droplets, thereby reducing the Coulomb force existing between two adjacent ink droplets, making the offset of the charged ink droplets as small as possible, and improving the precision of the ink droplet landing. In the traditional scheme, the first 16 ink droplets are charged with 400mC, 380mC, 360mC, 340mC, 320mC, 300mC, 280mC, 260mC, 240mC, 220mC, 200mC, 180mC, 160mC, 140mC, 120mC, 100mC The drip charge is also arranged in this way). But this will cause the front ink drop to be subjected to Coulomb force greatly, and the rear ink drop will be subject to Coulomb force less. In this algorithm, we first charge the ink droplets sequentially, but the charging sequence (the first 16) is 400mC, 100mC, 380mC, 120mC, 360mC, 140mC, 340mC, 160mC, 320mC, 180mC, 300mC, 200mC, 280mC, 220mC , 260mC, 240m. Due to the arrangement in this way, the Coulomb force received by each ink droplet is not much different (co...

Abstract

The invention relates to the technical field of small character ink jet printers, in particular to an improvement based ink droplet charging small character nozzle jet printing method which comprisesthe following steps of S1, electrifying an ink jet printer for initialization, spraying ink droplets through a small character nozzle, and charging the ink droplets; S2, arranging the charged ink droplets according to a required sequence; S3, judging whether the charge quantity of the charged ink droplets meets a preset requirement or not; S4, if the charge quantity in S3 does not meet the requirement, returning to the S1 for recharging, and if the requirement is met, entering S5; and S5, enabling the ink droplets to participate to jet printing, splicing the landing positions of the ink droplets to enable the ink droplets to reach expected positions, and finishing jet printing. By adopting the improvement based ink droplet charging small character nozzle jet printing method provided by theinvention, the problem that the ink droplets are difficultly printed on a straight line and are offset to lead to cause typing skew in the prior art is solved, and the accuracy is improved; ink droplets without meeting the charge quantity are recycled and are re-injected into an ink tank to participate to the printing operation process, so that the ink loss can be lowered, and the ink utilizationrate is increased.

Description

technical field [0001] The invention relates to the technical field of small-character inkjet printers, in particular to an improved ink droplet-charging small-character inkjet printing method. Background technique [0002] At present, the charging end of the small character inkjet printer mainly applies a certain pressure to the ink in the system by controlling the internal gear pump or supplying compressed gas from the outside of the machine, so that the ink is ejected through a nozzle with an aperture of tens of microns. The continuous ink line formed by ejecting from the nozzle is split into ink droplets of equal size and certain spacing under the action of the up and down vibration of the crystal driving rod inside the spray chamber, and then the ink droplets are respectively charged by induction when passing through the "charging" electrodes ;The electrostatically charged ink drop passes through the detection electrode to detect whether the actual charge of the ink dro...
