As shown in fig. 1, the utility model discloses a take pigment china ink agent ink feed mechanism of viscosity monitoring function, including ink horn, diaphragm pump, two three way solenoid valve and thinner box, the first ink outlet of ink horn is connected with the first feed inlet of diaphragm pump through big character inkjet printer shower nozzle, and the discharge gate of diaphragm pump connects back black pipeline and china ink agent viscosity detection pipeline in parallel, and back black pipeline and china ink agent viscosity detection pipeline are connected with the ink return mouth of ink horn respectively, and the second of ink horn is gone out black mouth and thinner box and is connected with the second feed inlet of diaphragm pump through two three way solenoid valve respectively.

The working principle is as follows: the compressor respectively provides outside air supply for ink horn and diluter box to respectively for ink horn and diluter box provide injection pressure, make partial china ink agent in getting into the diaphragm pump through the first ink outlet of ink horn, big character ink jet numbering machine shower nozzle and the first feed inlet of diaphragm pump in proper order, the china ink agent gets into in the ink horn through the discharge gate of diaphragm pump respectively through ink return pipeline and china ink agent viscosity detection way again. Wherein, the ink agent flows back into the ink box through the ink return pipeline, and the circulation of the ink agent in the nozzle is realized. The ink agent flows back into the ink box through the ink agent viscosity detection pipeline, and the real-time detection of the ink agent viscosity is realized.

When the ink agent viscosity detection pipeline detects that the ink agent viscosity is normal, partial ink agent in the ink box enters the diaphragm pump through a second ink outlet of the ink box, the two-position three-way electromagnetic valve and a second feed inlet of the diaphragm pump in sequence, and the dispersive stirring of the ink agent in the ink box is realized.

When the ink viscosity detection pipeline detects that the ink viscosity rises, the two-position three-way electromagnetic valve is opened for a short time, so that the pipeline between the diluent box and the two-position three-way electromagnetic valve is communicated, the pipeline between the second ink outlet of the ink box and the two-position three-way electromagnetic valve is interrupted, the diaphragm pump sucks the diluent and sends the diluent to the ink box so as to dilute the ink until the ink viscosity returns to be normal, the ink viscosity is ensured, and the jet printing effect is ensured.

A filter is arranged between the first ink outlet of the ink box and the feed inlet of the large-character code spraying machine nozzle, so that ink agent flowing to the nozzle is filtered, and impurities are prevented from being conveyed to the nozzle to cause blockage.

A buffer is arranged between a discharge hole of the spray head of the large-character code spraying machine and a first feed hole of the diaphragm pump, so that pressure fluctuation generated during the operation of the diaphragm pump is absorbed, and the stable internal pressure of the spray head is ensured.

A throttle valve and a viscometer are arranged on the ink viscosity detection pipeline.

The throttle valve controls the flow of ink on the ink viscosity detecting pipe.

The viscometer is used for detecting the viscosity of the ink, if the viscosity of the ink is normal, the controller controls the two-position three-way electromagnetic valve to be in a communication state with the ink box and to be in an interruption state with the diluent box, and if the viscosity of the ink is increased, the controller controls the two-position three-way electromagnetic valve to be in an interruption state with the ink box and to be in a communication state with the diluent box.

Preferably, the viscometer is a titration viscometer. Titration type viscometer, including main part 1, be equipped with collecting pit 3 in the main part 1, collect liquid chamber 6 and branch pipeline 5, the one end and the china ink agent entry 2 of branch pipeline 5 are connected, the one end and the branch pipeline 5 of collecting pit 3 are connected, the 3 other ends of collecting pit extend to in collecting liquid chamber 6, the other end and the collecting liquid chamber 6 of branch pipeline 5 are connected with the ink return mouth of ink horn respectively, 3 other end tip of collecting pit are equipped with

The ink agent flows through the titration type viscometer at low speed through the diaphragm pump, and the effect of detecting the viscosity of the ink agent is realized. Specifically, the ink first passes through the collecting tank 3 via the ink inlet 2, and when the collecting tank 3 is filled with the ink, the rest part of the ink directly flows back to the ink cartridge via the branch line 5. Under the action of gravity, ink in the collecting tank 3 drops into the liquid collecting cavity 6 in the form of ink drops through the titration nozzle 4, in the dropping process of the ink drops, the photoelectric sensor 7 collects signals passed by each ink drop and sends the signals to the controller in real time, and the controller compares the time of receiving a fixed number of ink drop signals with preset time according to each received ink drop signal so as to detect whether the viscosity of the ink rises or not. If the time for receiving the fixed number of drop signals is greater than the preset time, it indicates that the viscosity of the detected ink agent is increased. The preset time is the time consumed by the new equipment for dropping a fixed amount of standard ink after the new equipment is started to add the standard ink.
