The four groups of ink supply systems have the same structure and are respectively composed of an ink barrel, a peristaltic pump, a filter and a primary ink box, wherein the ink barrel is connected with a joint of the peristaltic pump through an ink supply rubber tube, the peristaltic pump is connected with the filter through a line, and the primary ink box is connected with a double-clamping valve through a pipeline. The filter is used for filtering solid particles larger than 5nm in the ink and preventing the spray holes of the spray head from being blocked.

The independent ink path control system is arranged on the movable trolley.

The utility model discloses the beneficial effect who brings does: the ink circulation supply is realized in the ink path through the structure of the independent ink path control system, the ink passes through the components such as an inking peristaltic pump, a filter and the like from the ink barrel and reaches the nozzle, then returns to the filter through the ink returning peristaltic pump component, and enters the ink path after being filtered to realize circulation, so that the stable ink circulation supply of the ink in the nozzle is always ensured, and the problem to be solved by the control system is 1, the stable ink circulation supply of the ink path; 2. the mechanism is arranged on a trolley which can be lifted at will, the spray head mechanism is also arranged above the trolley, can be used as an independent ink jet unit to move conveniently and arranged on other printing machines, fills up short plates which can not print variable data of other traditional printing machines, and is very practical.

Detailed Description

As shown in fig. 1, in the independent ink path control system of a four-color inkjet printer, four sets of ink supply systems are connected with a double-clamping valve 5 through a pipeline, the double-clamping valve 5 is connected with a four-color inkjet printing head 6 through a pipeline, the four-color inkjet printing head 6 is provided with a waste ink outlet and an ink return outlet, the waste ink outlet is connected with a waste ink peristaltic pump 8 through a pipeline, the ink return outlet is connected with an ink return peristaltic pump 7 through a pipeline, and the outlet of the ink return peristaltic pump 7 is connected with the ink supply systems through the pipeline. The double-card valve 5 is of a Menjet saia-burgess PN091558 model, is provided with C, M, Y, K four control valves, respectively controls the corresponding ink barrel 1, is equivalent to a valve, and has the function of stopping supplying ink to the spray head or supplying ink to the spray head, and when the printing spray head works, the valve is opened to supply pressure to prevent the ink in the pipeline from flowing backwards.

The four groups of ink supply systems have the same structure and are composed of an ink barrel 1, a peristaltic pump 2, a filter 3 and a primary ink box 4, wherein the ink barrel 1 is connected with a joint of the peristaltic pump 2 through an ink supply rubber tube, the peristaltic pump 2 is connected with the filter 3 through a line, and the primary ink box 4 is connected with a double-clamping valve 5 through a pipeline.

The independent ink path control system is arranged on the movable trolley.

The circulating ink supply mechanism is divided into two parts: the first part is: the four ink barrels 1 are respectively filled with inks of different colors, the inks of the four colors are supplied to the filter 3 by the power of the peristaltic pump 2 from the ink barrels 1, solid particles larger than 5nm are removed by the inks through the filter 3, the inks are prevented from blocking the spray holes of the spray heads and enter the primary ink box 4, the liquid level sensor is arranged at the position, which is higher than the middle, of the primary ink box 4, the sufficient amount of the inks is indicated after the inks reach the upper limit position of the sensor, at the moment, the peristaltic pump 2 stops working, the liquid level of the inks is correspondingly reduced to the lower limit of the liquid level sensor along with the consumption of the inks in the working process, and the peristaltic pump 2 works again to ensure; the second part is that: when the printing is ready, the ink return peristaltic pump 7 starts to work, the double-card valve 5 is opened at the same time, the four colors of ink flow through the double-card valve 5 through the primary ink box 4 to the four-color ink-jet printing head 6 to ensure that the ink chamber of the printing head 6 is filled with the ink all the time, the redundant ink returns to the liquid inlet 3-1 of the filter 3 through the action of the ink return peristaltic pump 7, wherein the ink return peristaltic pump 7 is connected with the ink return outlet 6-1 of the four-color ink-jet printing head 6 through a pipeline, the filtered ink is injected into the primary ink box 4 again for repeated use to ensure that the ink chamber of the printing head 6 is filled with the ink all the time, and waste ink generated by cleaning the printing head is pumped into a waste ink barrel 9 through the waste ink peristaltic pump 8 to be.

As shown in fig. 2 or fig. 3, the independent ink path control system can be flexibly installed on other printers to fill up a short board which can not print variable data, the four-color inkjet printing head 6 is flexibly installed on any printer, and simultaneously, an electric eye and a rotary encoder are installed to provide signal data for an electric control part to control the start and stop of printing, the mobile cart 11 can move the whole ink control system at any time on one hand, and can manually lift the whole ink control system on the other hand to adjust the liquid level difference between the four-color inkjet printing head 6 and the primary ink box 4 within 10 mm.

What has been described above is merely a preferred embodiment of the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications and improvements can be made, and shall be considered as belonging to the protection scope of the present invention.
