With the progress of society, the printing industry is also rapidly developed, and with the development of society, due to the defects of the traditional printing technology, such as low printing speed, no environmental pollution of printing ink, large printing material single, and incapability of being applied to different materials, the requirements of the current market cannot be met. The computer technology is gradually developed to form a high and new technology product integrating mechanical and computer electronic information technology into a whole: digital printers, commonly known as UV printers, also known as flatbed printing, are one of the most important items in the printing industry. Corresponding to the traditional printing technology, the digital printing has many advantages, such as diversification of printing materials, wide application fields, such as the fields of paper, wall bricks, wood boards, clothes and the like, can print a larger size range at one time, and has high printing precision. And the used ink is green and environment-friendly, and has the characteristics of instant rapid curing, no volatile organic solvent (VOC) and less pollution. It is increasingly in the field due to its many advantages.

The existing digital printer mainly comprises a printer, a support frame and a driving device for driving the printer to move, wherein the printer mainly prints ink through a spray head. The existing printing ink of the printer has various colors and various brands, so the quality of the printing ink is different, although the colors of the printing ink are different, a lot of materials can use white ink when the printing is carried out, the white ink can adjust the hue of the color printing ink, the relief effect is embodied, and the printed pattern effect is vivid. However, white ink often has the problem of larger particles, especially poor white ink, and white ink can generate precipitates when the white ink is static, and the blockage of the spray head can be caused when more precipitates are aggregated to form bulk impurities due to the smaller inner diameter of the spray head. There is therefore a need for a system that can circulate white ink in the channels of a digital printer while it is suspended from printing.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

A white ink circulating system of a printer comprises an ink cabin 1 and a spray head 2, wherein the ink cabin 1 is installed in a support frame 15 of the printer, and the spray head 2 is fixedly arranged on a movable support 16. A circulating delivery system is provided between the ink tank 1 and the ejection head 2, wherein the circulating delivery system includes a delivery pump 3, a control valve 6, and a negative pressure pump 14. The ink cabin 1 is provided with a conveying pipe 9 extending into the bottom of the inner side, the upper end of the conveying pipe 9 extends out of the ink cabin 1 and is communicated with an inlet of a conveying pump 3, an outlet of the conveying pump 3 is communicated with an inlet of a transition valve 8, an outlet of the transition valve 8 is communicated with an inlet of a one-way valve 4, an outlet of the one-way valve 4 is communicated with a transition cabin 5, the transition cabin 5 is also communicated with an inlet of a control valve 6, the other end of the control valve 6 is communicated with the spray head 2, and a feed inlet of the spray head 2 is also connected with a negative pressure pump 14 for preventing ink from falling. While the pod 5 is also in communication with a feed tube 13 via the intermediate valve 7, the feed tube 13 extending into the interior of the ink tank 1 and the lower end of the feed tube 13 being located at the upper end of the ink tank 1, thereby forming a passage for facilitating circulation of the white ink. Foretell transfer pump 3 is the peristaltic pump, can realize that the circulation of white ink is incessant to be carried and the accurate controllable of pay-off volume through setting up of peristaltic pump.

A porous buffer plate 10 is arranged in the ink cabin 1, the buffer plate 10 is arranged at the upper end part of the ink cabin 1 and is positioned below the feeding pipe 13, and the buffer plate 10 is obliquely arranged in the ink cabin 1; a filter layer 11 is arranged below the buffer plate 10, and the filter layer 11 is close to the buffer plate 10. Meanwhile, a liquid level meter 12 for detecting the liquid level is also arranged in the ink chamber 1. When the white ink enters the ink tank 1 through the feeding pipe 13, the white ink firstly falls onto the buffer plate 10, the liquid level can obliquely flow along the buffer plate 10 due to the inclined arrangement of the buffer plate 10, and the white ink flows into the filter layer 11 from the holes formed in the buffer plate 10 and enters the ink tank 1 after being filtered.

The transition valve 8, the control valve 6, the intermediate valve 7, the liquid level meter 12 and the peristaltic pump are all connected with a control system of a printer, the transition valve 8, the control valve 6 and the intermediate valve 7 are all two-way electromagnetic valves, the on-off of the two-way electromagnetic valves is controlled through the control system, and the control system drives a motor to rotate, so that the prior art is provided.
