[0020] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: an ink filtering device for water-based ink production, including an outer barrel 1, a discharge port 2 is connected to one side of the outer barrel 1, a connecting pipe 3 is connected to the other side of the outer barrel 1, an installation groove 4 is arranged inside the outer barrel 1, an inner barrel 5 is connected inside the outer barrel 1, a card slot 19 is arranged above the outer barrel 1, one end of the connecting pipe 3 extending into the inner part of the outer barrel 1 is connected with a spraying head 20, a clamping strip 18 is engaged with the card slot 19, one end of the discharge port 2 is connected with the inner barrel 5 in a penetrating manner. By connecting a water pipe to the connecting pipe 3, the spraying head 20 can spray clean water, thereby cleaning the inner barrel 5 and the filter cartridge 8, saving labor and improving the cleaning efficiency.

[0022] A material guiding plate 6 is installed above the outer barrel 1, handles 16 are connected to both sides of the material guiding plate 6, a sieve plate 17 is connected to the material guiding plate 6, and a clamping strip 18 is connected below the material guiding plate 6. By the way of fixing the material guiding plate 6 on the outer barrel 1 through the engagement of the clamping strip 18 and the card slot 19, it is convenient for the staff to install and disassemble the material guiding plate 6, so as to timely maintain and clean the material guiding plate 6 and avoid the sieve plate 17 being blocked by impurities after long-term use.

[0023] A plurality of slide grooves 7 are opened on the inner wall of the inner barrel 5, a filter cartridge 8 is slidably connected inside the inner barrel 5, electric push rods 9 are fixedly installed on both sides above the inner barrel 5, a plurality of limit strips 21 are connected to the filter cartridge 8, and there are six limit strips 21 evenly distributed in a centrosymmetric manner. The movable end of the electric push rod 9 is connected with the limit strip 21, and the limit strip 21 slides in the slide groove 7. Through the sliding of the limit strip 21 in the slide groove 7 and the symmetrically installed electric push rods 9, the filter cartridge 8 can slide smoothly inside the inner barrel 5, avoiding the filter cartridge 8 from skewing when moving.

[0024] A motor 10 is fixedly installed in the installation groove 4. The output shaft of the motor 10 is connected to a rotating rod 11. A plurality of stirring rods 12 are connected to the rotating rod 11. A scraping plate 13 is connected to the rotating rod 11. A support frame 22 is connected to the outer barrel 1. A bottom plate 23 is connected below the support frame 22. An anti-slip pad 24 is connected below the bottom plate 23. The outer barrel 1 is supported by the support frame 22. The bottom plate 23 can increase the contact surface with the ground, and the anti-slip pad 24 can increase the friction with the ground, thereby improving the stability of the placement of the filtering device.

[0025] A limiting ring 14 is arranged on the rotating rod 11. A filter plate 15 is connected between the two limiting rings 14. The filter plate 15 is rotatably connected to the rotating rod 11. A groove 25 is arranged on the filter plate 15. The filter cylinder 8 is fitted with the groove 25, and a sealing ring is arranged on the inner wall of the groove 25. The scraping plate 13 contacts the inner wall of the filter cylinder 8 and the filter plate 15. By synchronously starting the two electric push rods 9 to push the filter cylinder 8 downward, as the filter cylinder 8 moves, the lower end of the filter cylinder 8 will be fitted with the groove 25, so as to combine the filter plate 15 and the filter cylinder 8 together for the filtering work, and the sealing ring on the inner wall of the groove 25 can prevent liquid leakage.

[0026] The working principle of the present utility model is as follows:

[0027] The staff first snaps the clamping strip 18 into the clamping groove 19, thereby installing and fixing the material guiding plate 6 on the outer barrel 1. Then, the ink is poured onto the material guiding plate 6. The ink will flow along the material guiding plate 6 and finally flow through the sieve plate 17 for primary filtration to remove large particle impurities in the ink. Then, the ink will flow into the filter cylinder 8. At this time, the motor 10 will rotate the rotating rod 11, so that the stirring rod 12 and the scraping plate 13 rotate together. The stirring rod 12 can stir the ink in the filter cylinder 8, and the scraping plate 13 can scrape off the impurities blocking the holes, thereby completing the filtering work of the ink. Then, a water pipe is connected to the connecting pipe 3 so that the spraying head 20 can spray clean water into the inner barrel 5 and the filter cylinder 8. At this time, the rotating rod 11 continues to rotate, and the scraping plate 13 scrapes off the ink and impurities attached to the inner wall and holes of the filter cylinder 8. Then, the two electric push rods 9 are synchronously started to pull the filter cylinder 8 upward, prompting the filter cylinder 8 to separate from the filter plate 15. Finally, the sewage and impurities will be discharged from the discharge port 2.
