Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example 1:

referring to fig. 1, a degassing circulation device for an ink jet printer, comprising a secondary ink tank 1, wherein the secondary ink tank 1 is respectively communicated with a main ink tank and a printing nozzle for continuously supplying ink to the printing nozzle, and the improvement is that: one side of second grade ink horn 1 has concatenated ink pump 2, filter 4 and degasser 5 in proper order, degasser 5's the other end with second grade ink horn 1's opposite side is linked together, ink pump 2 is used for providing power for the flow of ink, filter 4 is used for filtering the impurity in the ink, degasser 5 is used for taking off the air in the ink, and the ink in the second grade ink horn 1 flows through in proper order under the drive of ink pump 2 filter 4 with it flows back to second grade ink horn 1's the black intracavity in order to remove impurity and air in the ink behind the degasser 5.

In this embodiment, the continuous supply of the ink in the second grade ink box 1 prints the shower nozzle to guarantee the continuous inkjet of printing the shower nozzle, consequently need continuous supplementary ink in the second grade ink box 1, the ink can continuous production microbubble when getting into the second grade ink box and when flowing in the second grade ink box, and the microbubble swallows each other and can form great bubble, can lead to the phenomenon that the printing in-process appears empty spouting after great bubble gets into and prints the shower nozzle, influences the printing quality. This embodiment sets up degasification circulation ink route in second grade ink horn 1 department, the ink gets into the china ink chamber of second grade ink horn 1 by main ink tank, and keep certain ink volume, the ink in the china ink chamber of second grade ink horn 1 is under the drive of ink pump 2, at first flow through filter 4, filter the solid particle in the ink, impurity such as sediment, then flow through degasser 5, the air that dissolves in the ink is constantly appeared, in the printing process, ink pump 2 keeps low power operation, so continuous circulation, both guaranteed that the ink in the second grade ink horn has good mobility, in order to reduce the production of sediment, can remove the micro bubble in the ink, avoid these micro bubble to swallow each other and form the big bubble, thereby reduce the air content in the ink that gets into the printing shower nozzle, avoid the phenomenon that the printing in-process appears the empty jet, and then improve the printing quality.

According to the degassing circulation ink path for the ink-jet printer, the degassing circulation ink path is arranged at the position, closest to the printing nozzle, of the secondary ink box 1, and ink before entering the printing nozzle is continuously degassed, so that the air content of the ink entering the printing nozzle is reduced to the maximum extent, and the idle spraying phenomenon in the printing process is avoided better; in addition, the ink in the secondary ink box is guaranteed to have good fluidity, so that the generation of precipitates is reduced, the arrangement of the filter 4 reduces impurities in the ink, the situation that the impurities block an ink path or block a spray hole of a printing spray head is avoided, the printing process is prevented from being influenced, the damage to the spray head is avoided, the printing quality is effectively improved, and the loss is reduced.

Further, a liquid level sensor is arranged in an ink cavity of the secondary ink box 1, and the liquid level sensor is a capacitance type liquid level sensor. The liquid level sensor is used for detecting the ink amount in the ink cavity of the secondary ink box 1, avoids the damage of components and parts caused by the reverse suction of ink due to the overhigh ink amount, and simultaneously avoids the influence on the printing process caused by the ink shortage due to the overlow ink amount. The capacitance type liquid level sensor 3 has the characteristics of high precision, high stability, continuous measurement and the like, and has a better detection effect.

Further, the degassing device 5 is an air filter.

Example 2:

on the basis of embodiment 1, the main ink tank is communicated with the filter 4, the degassing device 5 and the secondary ink box 1 in sequence, and the ink in the main ink tank flows out of the main ink tank, flows through the filter 4 and the degassing device 5 in sequence, then flows into the ink cavity of the secondary ink box 1, and is supplied to the printing head by the secondary ink box 1.

In this embodiment, before the ink in the main ink jar got into second grade ink horn 1, at first flow through filter 4, filter solid particle in the ink, impurity such as sediment, then flow through degasser 5, the air that dissolves in the ink is continuous to be appeared, thereby guarantee that the ink that gets into in second grade ink horn 1 has less air content and less impurity, the degasification circulation ink path of collocation setting in second grade ink horn 1 department, can more effectively get rid of the air that gets into in the ink of printing the shower nozzle and the content of impurity, thereby avoid the condition emergence of empty spout and jam, and then improve the printing quality.

Further, the main ink tank, the ink pump 2 and the filter 4 are communicated with each other through a three-way joint 3.

Example 3:

on the basis of

embodiment

1 or 2, referring to fig. 1 and 2, a first ink outlet joint 11 is arranged at the lower part of one side of the secondary ink box 1, an ink inlet joint 12 is arranged at the middle part of the other side of the secondary ink box 1, the ink pump 2 is communicated with the secondary ink box 1 through the first ink outlet joint 11, and the other end of the degassing device 5 is communicated with the secondary ink box 1 through the ink inlet joint 12.

Further, a plurality of second ink outlet connectors 13 are arranged at the bottom of the secondary ink box 1, and the second ink outlet connectors 13 are communicated with the printing nozzle.

In this embodiment, because the ink bumps and can produce the microbubble with second grade ink horn inner wall and the interior ink of second grade ink horn when the ink gets into the second grade ink horn to the bubble leads to the bubble content in the upper ink in the second grade ink horn because the quality can constantly come up lighter, and the bubble content is minimum in the lower floor's ink, and the ink gets into the second grade ink horn from the middle part, has guaranteed that the ink of second grade ink horn bottom compares and has less bubble content in the ink on upper strata all the time. In addition, impurities in the ink can sink to the bottom of the secondary ink box due to the heavy weight, so that the first ink outlet joint 11 is arranged at the lower part of the secondary ink box, the ink inlet joint 12 is arranged at the middle part of the secondary ink box, good flowing between the upper layer ink and the lower layer ink of the secondary ink box is ensured, the generation of precipitates is reduced, the impurities at the bottom continuously flow out of the secondary ink box and are filtered by a filter, and the impurities in the ink are further reduced; the second ink outlet joint 13 directly communicated with the printing nozzle is arranged at the bottom of the secondary ink box, so that the minimum content of bubbles in ink entering the printing nozzle is ensured, and the printing quality is improved.
