preferably, the ink pump 7 of the present invention employs a LLP04 diaphragm pump manufactured by Kachuan fluid technology, Inc.
The continuous ink supply system work flow of the ink pump is as follows:
Firstly, pipelines of all parts are connected in a sealing mode, then the ink pump is debugged before supplying ink, the ink amount is adjusted according to requirements, then the ink pump 7 is controlled to be opened through a control panel, ink is sucked out of the ink box 4 and flows into the ink pump 7 through an inlet of the ink pump 7, the working principle of the ink pump 7 is a positive displacement pump principle, and the ink is discharged from an outlet by the ink pump 7 and enters a main pipe inlet of the first T-shaped three-way pipe 51. The ink with larger flow rate and flow rate flows back to the ink box 4 through the main pipe outlet of the first T-shaped three-way pipe 51 for recycling of the ink; the slower flow rate of ink flows through the branch outlet of the first tee 51 into the main inlet of the second tee 52. At this moment, the ink supply system performs first pipeline pressure reduction, so that ink supply is stable. Then, the relatively gentle ink which is subjected to the primary pressure reduction flows through the second T-shaped tee pipe 52, wherein a part of the ink with relatively large flow rate and flow rate flows back to the ink box through the main pipe outlet of the second T-shaped tee pipe 52 and the second straight pipe 15 for next recycling; while the more gradual portion of the flow rate of the ink flows through the branch outlet of the second T-tee 52 into the inlet of the filter 6. At this moment, the ink of the ink supply system is subjected to secondary pressure reduction, and the state tends to be more stable. Finally, the ink stably reaches the nozzle connecting piece 2 through the filtering action of the filter 6, and finally flows into the nozzle through the sealing to perform jet printing.
