Problems solved by technology

[0005] However, the structure of these devices is also relatively complicated, and the manufacturing cost is high. At the same time, the filter cartridge needs to be removed for cleaning when cleaning, and automatic cleaning cannot be realized. The operation is inconvenient in practical applications, which affects its promotion and application in production.

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

A printing ink filtering device comprises a filtering cylinder; an outer ink cavity and an inner ink cavity are concentrically formed in the filtering cylinder and communicated through a cylindrical screen; a rotating shaft is arranged in the inner ink cavity; stirring blades are arranged on the rotating shaft and comprise supporting frames and flexible scraping pieces; a containing cavity is formed in each supporting frame, the top of each containing cavity is of a cambered surface structure, and the bottom of each containing cavity is of a flat plate structure; screen holes communicated with the inner ink cavity are formed in the tops and the bottoms of the containing cavities; notches are formed in the ends, close to the cylindrical screen, of the containing cavities, and a gap is formed between each notch and the cylindrical screen; and the flexible scraping pieces are arranged in the containing cavities, one end of each flexible scraping piece is a fixed end, and the other end of each flexible scraping piece is a free end. The device is unique in 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 ...
