Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, a special ink path system for an inkjet printer includes an ink supply loop, a recovery loop, a cleaning loop, a solvent adding loop, and an ink adding loop, wherein the ink supply loop includes a mixing cylinder 1, a pre-pump filter 2, a pump 3, a pressure sensor 4, a main filter 5, an ink supply valve 6, a nozzle filter 7, and a nozzle 8, which are connected in sequence; the recovery loop comprises a recoverer 9, a recovery valve 10, a recovery pump 11 and a mixing cylinder 1 which are connected in sequence; the cleaning loop comprises a solvent cylinder 12, a cleaning pump 13, a cleaning valve 14, a filter 15 and a nozzle 8 which are connected in sequence; the solvent adding loop comprises a solvent cylinder 12, a solvent adding valve 16, a recovery pump 11 and a mixing cylinder 1 which are connected in sequence; the ink adding loop comprises an ink cylinder 17, an ink adding valve 18, a recovery pump 11 and a mixing cylinder 1 which are connected in sequence;

more specifically, in the ink supply loop, a pressure buffer tank 19 is arranged between the pump and the pressure sensor, so that the pressure is ensured to be constant, the actual working time of the main pump is greatly reduced, the stable work of a machine is ensured, and the use of the main pump is prolonged;

more specifically, the ink jet printer further comprises a viscosity detection circuit, wherein the viscosity detection circuit comprises a viscosity filter, a viscometer 21, a viscosity detection valve 20 and a recovery pump 11 which are sequentially connected with the mixing cylinder 1, and the recovery pump 11 returns the detected ink to the mixing cylinder 1;

the viscometer has the following working principle: the viscosimeter during operation, viscosity detection valve opens, and the bobble is by jack-up viscosimeter's top under the effect of china ink stream, sets for the time of acquiescence opening viscosity detection valve through external control ware, guarantees that the bobble must be by the top of jack-up viscosimeter, and later viscosity detection valve closes, and the bobble falls under the effect of gravity, detects the viscosity of the ink that the whereabouts time of bobble was very tested out, and is higher when viscosity, and the resistance that the bobble whereabouts met is big more, and the time of whereabouts is just longer.

The specific working principle is as follows:

when code spraying is needed, an external controller controls an ink supply valve to be opened, a pump is started, ink in the mixing cylinder is extracted and is conveyed to a nozzle through a pipeline for printing, a recoverer is arranged below the nozzle and can recover unused ink sprayed outside, a recovery valve is controlled to conduct a C-R head and a P-R head, and the unused ink passing through the nozzle and the unused ink sprayed outside through the nozzle are recovered into the mixing cylinder under the action of the recovery pump; when cleaning is needed, the controller controls the cleaning valve to be opened, the cleaning pump works, the solvent in the solvent cylinder is extracted, and the solvent is filtered by the filter and then is conveyed to the nozzle for cleaning; when ink needs to be added, the controller controls the ink adding valve to be opened, the recovery pump works, and the ink in the ink cylinder is pumped into the mixing cylinder; when the solvent needs to be added, the controller controls the solvent adding valve to be opened, the recovery pump works, and the solvent in the solvent cylinder is pumped into the mixing cylinder; when viscosity detection is needed, the controller controls the viscosity detection valve to be opened, the recovery pump works, ink enters the viscometer to be detected, results are fed back to the controller, and the controller adds ink or solvent to the ink in the mixing cylinder according to the viscosity, so that the concentration of the ink meets the requirement.
