[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 3, an embodiment provided by the utility model: a high-efficiency high-pressure filtering device for ink, comprising a main body 1, a feed pipe 8 is fixedly connected to the right end of the top of the main body 1, a sealing door 29 is rotatably connected to the middle of the front end of the main body 1, a booster pump 9 is fixedly connected to the middle of the top end of the main body 1, an output end of the booster pump 9 is fixedly connected to a pressure transmission pipe 10, a terminal end of the pressure transmission pipe 10 penetrates through the top end of the main body 1 and is fixedly connected to a pressure transmission block 11, a connection groove 2 is opened at the bottom end of the main body 1, and a discharge filtering assembly is threadedly connected to the connection groove 2. A support block 12 is fixedly connected to the bottom end inside the main body 1, a first connection block 13 is fixedly connected to the top end of the support block 12, a filtering barrel 14 is arranged inside the main body 1, a second connection block 15 is fixedly connected to the middle of the bottom end of the filtering barrel 14, and the middle parts of the second connection block 15 and the first connection block 13 are threadedly connected. A driving assembly is arranged at the middle and lower part of the front end of the main body 1, and one end of the driving assembly is fixedly connected to the bottom end of the support block 12. Placing grooves 23 are opened at the left and right ends of the top of the main body 1, and cleaning assemblies are slidably connected inside the two placing grooves 23. Through holes 22 are opened at the left and right ends outside the support block 12 at the bottom end of the main body 1.

[0024] The ink enters the inside of the main body 1 through the feed pipe 8 and falls into the filtering barrel 14 for rough filtering. Pressure is applied to the inside of the main body 1 through the booster pump 9, the pressure transmission pipe 10 and the pressure transmission block 11 to accelerate the filtering speed of the ink. The filtered ink flows into the discharge filtering assembly through the through holes 22, and then flows out through the fine filtering of the discharge filtering assembly. When the filter holes on the filtering barrel 14 are blocked, the filtering barrel 14 is rotated through the driving assembly, and the particles or impurities in the filter holes are pounded out in cooperation with the two cleaning assemblies, solving the problem of blockage of the filtering barrel 14. The cleaning assembly can be taken out by pulling it upward, the discharge filtering assembly can be taken off by separating the discharge filtering assembly from the connection groove 2, and the sealing door 29 is opened to rotate the second connection block 15 to separate the filtering barrel 14 from the support block 12, facilitating the replacement of components.

[0025] Refer to Figure 2 , the discharge filtering assembly includes a discharge hopper 3, an annular block 4 is fixedly connected to the top end of the discharge hopper 3, the annular block 4 is threadedly connected to the connection groove 2, a discharge pipe 6 is fixedly connected to the bottom end of the annular block 4, a filter cloth 5 is arranged inside the annular block 4, and an outer wall of the filter cloth 5 is attached to an inner wall of the annular block 4. A valve 7 is fixedly connected to the outside of the discharge pipe 6.

[0026] The ink filtered by the filtering barrel 14 flows into the discharge hopper 3 through the through holes 22. The tiny impurities in the ink are adsorbed by the filter cloth 5, and then flow out through the discharge pipe 6, improving the quality of the filtered ink. By separating the annular block 4 from the connection groove 2, the replacement of the filter cloth 5 is facilitated, and the valve 7 controls the outflow of the ink.

[0027] Refer to Figure 3 and Figure 4, The driving component includes a motor 17 and a fixed shaft 16. One side of the outer end of the motor 17 is fixedly connected to the middle and lower part of the front end of the main body 1. The top of the fixed shaft 16 is fixedly connected to the middle part of the bottom end of the support block 12. The output end of the motor 17 is fixedly connected to a rotating shaft 18. Conical gears one 19 are fixedly connected to the bottom ends of both the rotating shaft 18 and the fixed shaft 16. Conical gears two 20 are meshed and connected to the opposite sides of the two conical gears one 19. The two conical gears two 20 are connected by a connecting shaft 21. The front end of the connecting shaft 21 is fixedly connected to the rear end of the front conical gear two 20. The rear end of the connecting shaft 21 penetrates through the bottom end of the front side of the main body 1 and is fixedly connected to the front end of the rear conical gear two 20.

[0028] The driving motor 17 rotates the rotating shaft 18 and the front conical gear one 19, driving the front conical gear two 20 to rotate. Thus, the connecting shaft 21 and the rear conical gear two 20 are rotated. When the rear conical gear two 20 rotates, it drives the rear conical gear one 19, the fixed shaft 16, and the support block 12 to rotate synchronously.

[0029] Refer to Figure 3 , The cleaning component includes a brush plate 24. The bottom end of the brush plate 24 fits against the bottom end of the placement groove 23. A number of bristles 25 are fixedly connected to the side of the brush plate 24 close to the inner wall of the main body 1. The bristles 25 fit against the outer side of the filter barrel 14. The top end of the brush plate 24 is fixedly connected to a brush handle 26. The top end of the brush handle 26 is fixedly connected to a fixed block 27. The bottom end of the fixed block 27 is flush with the top of the main body 1. The middle part of the top end of the fixed block 27 is fixedly connected to a pull ring 28.

[0030] The bristles 25 cooperate with the rotation of the filter barrel 14 to push the particles or impurities blocked in the filter holes into the interior of the filter barrel 14, and at the same time clean the outer side of the filter barrel 14. By pulling the pull ring 28, it is convenient to take out the brush handle 26, the brush plate 24, and the bristles 25.

[0031] Working principle: The ink enters the interior of the main body 1 through the feed pipe 8 and falls into the filter barrel 14 for rough filtration. The filtered ink flows into the discharge hopper 3 through the through holes 22, and then flows out through the discharge pipe 6 after fine filtration by the filter cloth 5. When the filter holes on the filter barrel 14 are blocked, the driving motor 17 rotates the filter barrel 14, and cooperates with the bristles 25 on the brush plate 24 to poke out the particles or impurities in the filter holes. Pulling the pull ring 28 upwards can take out the brush handle 26, the brush plate 24, and the bristles 25. By opening the sealing door 29 and rotating the connecting block two 15, the filter barrel 14 can be taken out from the interior of the main body 1 for replacement. By separating the connecting groove 2 and the annular block 4, the discharge hopper 3 can be taken off from the bottom of the main body 1, and the filter cloth 5 can be replaced.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
