Embodiment Construction
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0028] This embodiment takes double filter cartridges as an example for illustration.
[0029] Such as Figure 1 to Figure 5 shown.
[0030] The ink filtering device includes a filter cartridge, an ink inlet pipe 3 and an ink outlet pipe 4. An outer ink chamber 5 and an inner ink chamber 6 are concentrically arranged inside the filter cartridge, and the outer ink chamber 5 and the inner ink chamber 6 are communicated through a cylindrical screen 7 , the outer ink chamber 5 is connected to the ink outlet pipe 4 , and the inner ink chamber 6 is connected to the ink inlet pipe 3 . Ink enters from the ink inlet pipe 3, flows out from the ink outlet pipe 4 after passing through the inner ink chamber 6 and the outer ink chamber 5 in sequence.

Abstract
The ink filtering device includes a filter cartridge, an outer ink chamber and an inner ink chamber are concentrically arranged inside the filter cartridge, and the outer ink chamber and the inner ink chamber are connected through a cylindrical screen, and a rotating shaft is arranged in the inner ink chamber, on which A stirring blade is provided, and the stirring blade includes a support frame and a flexible scraper, and an accommodation cavity is arranged in the support frame, the top of the accommodation cavity is an arc surface structure, the bottom of the accommodation cavity is a flat plate structure, and the top and bottom of the accommodation cavity are provided with the inner ink The cavity is connected to the sieve hole. A notch is opened on the end of the accommodating cavity close to the cylindrical sieve. There is a gap between the notch and the cylindrical sieve. The flexible scraper is arranged in the accommodating cavity. One end is a fixed end, and the other end of the flexible scraper is a free end. The invention has a unique structure and can realize self-cleaning and high-efficiency filtration without affecting production.
Description
technical field [0001] The invention relates to the technical field of printing equipment, in particular to an ink filter device. Background technique [0002] There are many sources of pollution in ink production. Due to complex production, there are various types of impurities, such as fibers, solids and semi-solids, etc., so it is necessary to filter to remove pollutants and avoid contamination during printing. Smearing and other traces are eliminated to ensure clear, concise and high-resolution graphics for printing. Ink filtration is an important part of the printing ink supply system. At present, most of the ink filtration adopts the way of circulating ink through imported filters. stop, thereby affecting production efficiency. [0003] A large amount of research and development has also been carried out in China. For example, the Chinese patent application number 201520532650.0 discloses an ink filter device for a gravure printing machine, including an ink pump, an ...
