Description

Technical Field

[0001] The utility model relates to the technical field of ink filtration, in particular to a negative pressure filtration device for UV ink. Background Art

[0002] UV inkjet ink is an economical and efficient ink with a very wide range of application fields. The market advantage of UV inkjet ink lies in that the diameter of pigment particles is less than 1 micron, it does not contain volatile organic solvents, has ultra-low viscosity, no pungent odor, and can ensure that there is no phenomenon of nozzle blockage during the inkjet printing process. Therefore, a filtration device is often needed to precisely filter the ink particle impurities during the production process.

[0003] Currently, when filtering UV inkjet ink, negative pressure assistance is generally used to achieve rapid filtration of the ink. However, during negative pressure filtration, the negative pressure inside the filter cylinder cannot be monitored in real time, so an appropriate negative pressure range cannot be maintained, reducing the filtration efficiency and filtration effect of UV inkjet ink. For this reason, we propose a negative pressure filtration device for UV ink to solve the above problems. Summary of the Utility Model
