Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a multi-stage ink filtration device. Background Technology

[0002] Ink is an important material used in printing. It is used to display patterns and text on a substrate through printing or inkjet printing. During the production process, filtration devices are used to filter the ink, which improves the quality of the produced ink.

[0003] Existing ink filtration devices cannot scrape off residual ink from the inner wall of the filter barrel. The residual ink will adhere to the inner wall of the filter barrel. Over time, this ink may gradually accumulate and form blockages. Blockages will not only affect the normal operation of the filtration device, but may also lead to a decrease in filtration efficiency. The residual ink on the inner wall of the filter barrel will occupy a certain space, reduce the filtration area, and cause more ink to be unable to be effectively filtered, thereby reducing filtration efficiency. Moreover, the residual ink cannot be recycled and reused, increasing production costs.

[0004] Therefore, we have made improvements to this and proposed a multi-stage ink filtration device. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to address the fact that existing ink filtration devices cannot scrape off the ink residue on the inner wall of the filter barrel. The residual ink will adhere to the inner wall of the filter barrel, and over time, this ink may gradually accumulate and form a blockage. The blockage will not only affect the normal operation of the filtration device, but may also lead to a decrease in filtration efficiency. The residual ink on the inner wall of the filter barrel will occupy a certain space, reduce the filtration area, and cause more ink to be unable to be effectively filtered, thereby reducing filtration efficiency. Moreover, the residual ink cannot be recycled and reused, increasing production costs.

[0006] Therefore, we have made improvements to this and proposed a multi-stage ink filtration device.

[0007] To achieve the above and other related objectives, this utility model provides the following technical solution:
