AI Technical Summary

Technical Problem

The circulating ink supply system of the existing inkjet printing equipment has problems such as uneven ink supply, inaccurate ink monitoring, and poor conveying fluency, resulting in poor printing color deviations and unstable pattern quality, which increases the cost of use.

Method used

A circulating ink supply system is designed, including a main ink cartridge, a main ink supply pump and multiple circulating ink supply units. The ink discharged from the nozzle during cleaning and other operations is collected through the circulating ink supply unit to realize the recycling of ink and reduce waste. The system is equipped with an ink supply damper and an ink return damper to control the flow of ink and ensure uniform supply.

Benefits of technology

It significantly reduces ink waste, reduces usage costs, ensures continuity and uniformity of ink supply, and improves the clarity and color accuracy of printing patterns.

Abstract

The invention relates to a circulating ink supply system which comprises a main ink box, a main ink supply pump and a plurality of circulating ink supply units, the main ink supply pump pumps external ink into the main ink box through a pipeline, and the circulating ink supply units communicate with the main ink box through pipelines; the circulating ink supply unit comprises a box body, one side of the box body is provided with a first ink supply port and a first ink return port, and the other side of the box body is provided with a second ink supply port and a second ink return port; an ink supply damper, an ink return damper, an auxiliary ink supply pump and an ink return pump are arranged in the box body. The auxiliary ink supply pump pumps out ink in the main ink box through the second ink supply port and conveys the ink to the spray head through the ink supply damper and the first ink supply port in sequence. The ink at the ink return end of the nozzle sequentially passes through the first ink return port, the ink return damper and the second ink return port to return to the main ink box to form circulation under the action of the ink return pump. The ink discharged by the spray head in the cleaning operation process is collected through the circulating ink supply unit, circulating ink supply is achieved, waste of the ink is remarkably reduced, and the use cost is reduced.
