Description
Technical Field
The invention relates to the technical field of ink-jet printers, in particular to a negative pressure module for an ink-jet printer.
Background
In order to ensure that an ink tank continuously, stably and properly supplies ink to the printing nozzle, a negative pressure mode is generally used for controlling the ink supply to the nozzle, and a positive pressure mode is used for inflating the blocked nozzle or flushing cleaning liquid to dredge a pipeline. When a color pattern is printed and a printing medium is not white, a layer of white ink is required to be sprayed on the medium to be used as background color, and then the color pattern is required to be printed on the printing medium sprayed with the white ink to ensure that the color of the pattern is bright.
In the negative pressure module of the ink jet printer in the prior art, because the density of the white ink is greater than that of the color ink, and the gravity of the white ink is greater under the same volume, the negative pressure value required by the white ink path is also greater, and usually one negative pressure system is adopted to adjust the negative pressure of the white ink, and the other negative pressure system is adopted to simultaneously adjust the negative pressures of all other color inks. For example, chinese patent CN203752685U discloses a negative pressure module for an inkjet printer, which comprises a first negative pressure block assembly, a second negative pressure block assembly, a first air pump, a second air pump, a negative pressure circuit board and a negative pressure mounting plate, wherein the first negative pressure block assembly is installed at one end of the wide side of the negative pressure mounting plate, the first air pump is installed at one end of the long side of the negative pressure mounting plate, and the first negative pressure block assembly is connected to the first air pump for controlling printing in a white ink negative pressure mode; the second negative pressure block combination is arranged at the other end of the wide side of the negative pressure mounting plate, the second air pump is arranged at one end of the long side of the negative pressure mounting plate and arranged side by side with the first air pump, and the second negative pressure block combination is connected with the second air pump and used for controlling printing in a color ink negative pressure mode.
The above prior art has the following problems:
when the printer normally works, the negative pressure value in each ink cavity of the secondary ink box continuously changes along with the printing, so that the negative pressure module is required to adjust the negative pressure value in each air channel in time to ensure that ink cannot drip from a nozzle under the action of gravity; on the other hand, the use amount of each color of ink is different, which causes a large difference in the negative pressure value in the ink chamber of each color, the negative pressure value in each ink chamber needs to be reasonably distributed when the negative pressure is adjusted, and the response time is slowed, thereby causing unstable ink supply and affecting the printing effect.
In order to ensure the high quality of a printed pattern, the adopted ink is generally quick-drying ink, and when the ink-jet printer works, because the use frequency of each nozzle is different, certain nozzles with low use frequency can be blocked, so that the ink-jet printer needs to start a positive pressure mode to dredge the nozzles every several hours, and in the prior art, a positive pressure pump is adopted to dredge all nozzles, and because the power of the positive pressure pump is limited, when the nozzles are too many, the dredging effect is not good; and when the mediation is finished, when the positive pressure is switched back to the negative pressure, all the ink chambers need to reset the negative pressure value, on one hand, because a negative pressure system needs to adjust the negative pressure values of a plurality of air paths, because the power of the air pump is limited, the adjustment efficiency is low, on the other hand, because the negative pressure value of each ink chamber is different, the negative pressure value is adjusted for a plurality of ink chambers by adopting a negative pressure system, the negative pressure values among the ink chambers can be mutually interfered, and the circuit board needs to be continuously and repeatedly calculated, so that the adjustment time is longer, the response speed is slower, the technical level requirement on an operator is higher, even technical support needs to be provided, and the after-sale cost is increased.
The negative pressure module of the above-mentioned ink jet printer among the prior art generally installs the electronic box on the printer, when the negative pressure module trouble needs to be changed, need all gas circuits all to tear down, installs again after changing the negative pressure module, and needs the negative pressure value of every gas circuit of unified adjustment, troublesome poeration and consume time for a long time.
In summary, the negative pressure module in the prior art has the following problems:
1) when the printer works normally, one negative pressure system adjusts the negative pressure values of all color inks, the adjustment efficiency is low, the ink supply is unstable, and the printing effect is influenced;
2) after the nozzle is dredged in the positive pressure mode, when the negative pressure mode is switched back, the adjustment efficiency of resetting the negative pressure value is low, and the negative pressure values of the multiple ink cavities interfere with each other, so that the adjustment time is longer, the technical requirements on operators are higher, even technical support needs to be provided, and the after-sale cost is increased;
