[0040] Optionally, the mixing device 3 is a static mixer.

[0045] Specifically, the first metering pump and the second metering pump are respectively used as the first conveying device 4 and the second conveying device 5 to convey the ink and the diluent respectively.

The setting of the control unit 12 eliminates the manual batching and material conveying operations and can also ensure the accuracy and efficiency of batching and feeding.

[0052] In this embodiment, the first metering pump and the second metering pump first operate according to the control method set by the PLC, and convey a part of the ink and a part of the methanol into the batching tank 6. The viscometer 7 in the batching tank 6 can measure the viscosity of the material inside. If the viscosity is too small, the PLC controls the first metering pump to operate and conveys some more ink into the batching tank 6 to ensure that the viscosity of the material in the batching tank 6 meets the requirements of the finished product. Then, the PLC controls the feeding pump to operate and conveys the prepared material in the batching tank 6 to the finished product tank 8. Under the action of the circulation pump, the material circulates between the finished product tank 8 and the feeding tray. The level gauge 11 in the feeding tray detects the level of the material in the feeding tray. As the ink printing progresses, the PLC controls the feeding pump to supply material to ensure that the level of the material in the ink supply tray 9 is maintained at the production level and the normal production is guaranteed.
