A constant pressure conductive-ink inking device belongs to the inking field of spraying-drawing machines, which comprises a relay, an air pump, an ink bottle, an ink filter, a cartridge and a flexible pipe, wherein a three-point touch switch with a liquid level maximum point and a liquid level minimum point is arranged in the cartridge for detecting the height of the conductive-ink liquid level, three points are respectively connected with relative ports of a transistor relay, the air pump is connected with the relative port of the transistor relay, and the compression port of the air pump is connected and fixed with the ink bottle, the ink filter and the cartridge through flexible pipes. A filter paper is arranged on the upper portion of the ink filter, a filter screen is arranged on the lower portion, and the ink flowing to the spraying-drawing machine solves the influences brought by a series of problems such as the dust or deposits after the secondary filter. The utility model realizes ink-providing automatically, solves all the defects added manually, maintains the constant pressure of the ink liquid level, and cannot influence the uniformity of the ink quantity of the spraying-drawing machine no matter how long the picture is.

Description

Constant voltage conductive ink ink-feeding device

Technical field

The utility model relates to the ink supply field of spray-drawing machine, refers to the constant voltage conduction ink-feeding device of air brushing machine especially.

Background technology

As everyone knows, the used ink feeding system of air brushing machine is the print cartridge formula now, that is to say that people added a certain amount of ink earlier before using the air brushing machine in print cartridge, and then starts working.After the air brushing machine was started working, the ink in the print cartridge can be along with the progress of spray figure in continuous minimizing; Be exactly ink accordingly to the hydraulic pressure of air brushing machine in continuous minimizing, so have influence on the air brushing machine go out what of China ink amount, the phenomenon of disconnected China ink also can appear when serious.If be smaller figure of spray at this moment, because be not too big with China ink amount, the hydraulic pressure of ink differs very not big when spray figure begins and during end, so also there is not what too big problem; But this moment, the air brushing machine was if in the words of spraying a big figure, because increase with the China ink amount, the hydraulic pressure of ink differs just very big when spray figure begins and when finishing, the black down heavy other end of an end that can obviously see figure so is black down light, even the situation of generation broken string, have a strong impact on the quality of spray figure, this is people's reason of always very much not being ready to spray big figure just; The shower nozzle of air brushing machine is accurate also more valuable thing in addition, if in the process that manually adds China ink, there are tiny article such as dust to fall into ink, then can cause and Mo Buchang, obstruction ink sac, blocking sprayer, so not only can influence quality and the output of spray figure, the service life that also can reduce shower nozzle greatly simultaneously; Perhaps have particulate deposits when after ink is parked for a long time, re-using in addition, when using such ink, also can have influence on out the phenomenon of Mo Buchang, obstruction ink sac, blocking sprayer.And these all are the present insurmountable problems of ink supply mode.

Summary of the invention

The purpose of this utility model is to provide a kind of constant voltage conductive ink ink-feeding device, 3 thoughts and feelings switches energy automatically supplying inks have been installed in print cartridge, use the good ink of electric conductivity, can remain the interior liquid level of print cartridge in certain height, thereby make the pressure of liquid level big variation can not take place, no matter spray great figure, also needn't but the heart dare not remove to spray big figure because of the problem of ink pressure, removed the various shortcoming that manually adds ink, this device adopts double filtration simultaneously, makes the ink that flows to the air brushing machine that reliable guarantee is provided.

The utility model is achieved in that by relay, air pump, ink bottle, ink filter device, print cartridge and flexible pipe to be formed, at first in ink bottle, pressurize with air pump, make electric conductivity ink automatic stream ink filter device, in the ink filter device, be provided with filter paper and filter screen, in adding black process, filter, ink through double filtration is sent to print cartridge again, uses for the air brushing machine.Ink adopts the good ink of electric conductivity, and the surface cock that is contained in the print cartridge can be worked normally.Close inner 3 thoughts and feelings switches installing at China ink, can be by the electric conductivity of conductive ink, the height of perception liquid level, when liquid level is lower than the position B point of setting, liquid level arrives part and switches on or off the thoughts and feelings switch, and switch passes to relay with the signal of perception, and relay just begins to connect the power supply of air pump, air pump is started working, realized adding black automation; When liquid level is higher than the height A point of setting, same thoughts and feelings switch can obtain a signal, and the signal of perception is passed to relay, make relay cut off the power supply of air pump, air pump is quit work, so circulation has guaranteed that just the liquid level in the print cartridge is in the altitude range of setting all the time, thereby has realized the constant voltage ink supply.

Superior effect of the present utility model is: be provided with 3 thoughts and feelings switches in print cartridge, the height of energy perception conductive ink liquid level, ink level is controlled in the scope of setting, can keep the constant voltage of ink level, you beat figure how long can not have influence on inhomogeneous that China ink is measured under the air brushing machine because of the variation of hydraulic pressure, solved in the past and had to cancel, and sprayed again once more having beaten a greater part of figure because of hydraulic problems; The utility model can be realized automatically supplying ink, all drawbacks of artificial interpolation have been removed, and employing double filtration, make the ink that flows to the air brushing machine through secondary filter, solve the influence that brings because of a series of problems such as dust or precipitations, prolonged the service life of shower nozzle, improved production efficiency, increase output, reduced production cost.
