Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly ink technology, and in particular to an environmentally friendly printing ink mixing and filtering device. Background Technology

[0002] In the research and development and production of environmentally friendly inks, the quality of ink formulation directly determines the performance and environmental indicators of the ink. However, formulated environmentally friendly inks often contain undissolved pigment particles, additive impurities, and minute contaminants. If these impurities are not effectively filtered, they will not only affect the core performance characteristics of the environmentally friendly ink, such as color uniformity and adhesion, but may also release harmful substances during use, violating environmental protection principles. Furthermore, they can lead to problems such as defects in printed patterns and dot clogging, reducing the quality of printed products.

[0003] In addition, the stirring mechanism of traditional devices is in a fixed position, and the stirring depth cannot be flexibly adjusted according to the liquid level of the ink in the stirring tank, resulting in insufficient stirring of the ink at the bottom; the impurities after filtration are inconvenient to clean, which can easily cause filter media blockage and affect the continuity of subsequent filtration operations. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly printing ink mixing and filtering device, which solves the problems of the fixed position of the stirring mechanism in the existing device, which cannot flexibly adjust the stirring depth according to the liquid level of the ink in the stirring tank, resulting in insufficient stirring of the ink at the bottom; and the inconvenience of cleaning the impurities after filtration, which easily causes filter media blockage and affects the continuity of subsequent filtration operations.

[0005] To achieve the above objectives, this utility model provides an environmentally friendly printing ink mixing and filtering device, including a base, a stirring assembly on the top of the base, and a filtering assembly on the top of the base. The stirring assembly includes a support rod, which is fixedly connected to the top of the base. A turntable is rotatably connected to the top of the support rod, and a mounting groove rod is fixedly connected to the top of the turntable. A lifting screw is rotatably connected between the inner top and inner bottom of the mounting groove rod. A nut block is threaded onto the outer wall of the lifting screw. A long rod is fixedly connected to one side of the nut block. A rotating shaft is rotatably connected to the bottom of one end of the long rod. A stirring impeller is fixedly connected to one end of the rotating shaft. A second servo motor is fixedly connected to the top of one end of the long rod, and the output shaft of the second servo motor is fixedly connected to one end of the rotating shaft.

[0006] Among them, a limiting slide rod is fixedly connected between the inner top and inner bottom of the mounting groove rod, and the limiting slide rod passes through the nut block and is slidably connected to its interior.

[0007] The top of the mounting groove rod is fixedly connected to a first servo motor, and the output shaft of the first servo motor is fixedly connected to one end of the lifting screw.

[0008] The turntable has an end face gear fixedly connected to its bottom, a third servo motor fixedly connected inside the support rod, and a drive gear fixedly connected to the output shaft of the third servo motor, which meshes with the end face gear.

[0009] The filter assembly includes two guard rods, which are fixedly connected to the top of the base. A first bracket and a second bracket are fixedly connected between the two guard rods, with the first bracket located above the second bracket.

[0010] The first support has a mixing tank fixedly connected to its inner wall, and a rotating shaft can extend into the mixing tank. The bottom of the mixing tank is funnel-shaped, and a valve is fixedly connected to the bottom outlet of the mixing tank.

[0011] The second support has a container fixedly connected to its inner wall, a centrifugal filter cylinder fixedly connected to its inner bottom, a valve located directly above the center of the centrifugal filter cylinder, a gear ring fixedly connected to the outer wall of the centrifugal filter cylinder, a fourth servo motor fixedly connected to the inside of the side wall of the second support, a drive gear fixedly connected to the output shaft of the fourth servo motor, the drive gear meshing with the gear ring, and a leakage hole provided at the bottom of the container, the leakage holes being arrayed along the outer edge of the centrifugal filter cylinder.

[0012] The filtering assembly also includes a collection container, which is movably placed on top of the base, below the holding bucket.

[0013] Beneficial effects Compared with existing technologies, it has the following advantages: 1. In this utility model, by setting a horizontally rotatable turntable and a vertically adjustable nut block, combined with the high-speed rotation of the stirring impeller, the stirring mechanism achieves all-round, multi-angle stirring. It can flexibly adjust the stirring depth according to the ink level, and the rotation of the turntable drives the stirring impeller to perform circular motion, effectively avoiding the problem of insufficient ink stirring in certain areas, significantly improving the uniformity of ink mixing, and ensuring the mixing quality of environmentally friendly printing inks.

[0014] 2. In this utility model, centrifugal filtration is used instead of traditional static filtration. The centrifugal filter cartridge is driven to rotate at high speed by a fourth servo motor.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Reference Figures 1-2 , Figures 4-5This utility model provides a technical solution: an environmentally friendly printing ink mixing and filtering device, including a base 1, which is made of high-strength metal material to ensure the stability of the overall structure. A stirring assembly 2 and a filtering assembly 3 are provided on the top of the base 1. The stirring assembly 2 is used to uniformly stir and mix the ink raw materials, and the filtering assembly 3 is used to filter impurities from the mixed ink. The stirring assembly 2 includes a support rod 21, which is vertically fixed to the top edge of the base 1. A turntable 22 is rotatably connected to the top of the support rod 21 via bearings, and the turntable 22 can rotate horizontally around the axis of the support rod 21. A mounting groove rod 24 is welded and fixed to the top of the turntable 22. The mounting groove rod 24 is a vertically arranged hollow groove structure, and its upper and lower ends are rotatably connected to lifting screws 25 via bearings. A nut block 27 is threadedly connected to the outer wall of the lifting screw 25, and a long rod 29 is bolted to one side of the nut block 27. The long rod 29 extends horizontally above the stirring tank 33. One end of the long rod 29 is rotatably connected to a rotating shaft 210 via a bearing. The rotating shaft 210 is vertically downward, and its lower end is fixedly connected to a stirring impeller 211. The stirring impeller 211 has a multi-blade structure, which can enhance the stirring effect. One end of the long rod 29 is fixedly connected to a second servo motor 212 via a bracket. The output shaft of the second servo motor 212 is fixedly connected to the upper end of the rotating shaft 210 via a coupling, which is used to drive the rotating shaft 210 and the stirring impeller 211 to rotate at high speed. A limiting slide rod 26 is also fixedly connected between the inner top and inner bottom of the mounting groove rod 24. The limiting slide rod 26 is arranged parallel to the lifting screw 25, and passes through the nut block 27 and is slidably connected to its interior. This can effectively prevent the nut block 27 from rotating with the lifting screw 25, ensuring that the nut block 27 rises and falls stably in the vertical direction. A first servo motor 28 is fixedly connected to the top of the mounting rod 24 via a bracket. The output shaft of the first servo motor 28 is fixedly connected to the upper end of the lifting screw 25 via a coupling. The forward and reverse rotation of the first servo motor 28 drives the lifting screw 25 to rotate, thereby adjusting the height of the nut block 27. An end face gear 23 is welded and fixed to the bottom of the turntable 22, and the end face gear 23 is coaxially arranged with the turntable 22. A third servo motor 213 is embedded and fixedly connected inside the support rod 21. The output shaft of the third servo motor 213 is horizontally arranged, and a drive gear 214 is fixedly connected to its end. The drive gear 214 meshes with the end face gear 23. The third servo motor 213 drives the drive gear 214 to rotate, which in turn drives the end face gear 23 and the turntable 22 to rotate synchronously, thereby adjusting the horizontal position of the stirring impeller 211.

[0020] Reference Figures 1 to 4 , Figure 6In one aspect of this embodiment, the filter assembly 3 includes two guard rods 31, which are symmetrically fixedly connected to the top of the base 1, located on one side of the support rod 21. A first bracket 32 ​​and a second bracket 35 are sequentially fixedly connected between the two guard rods 31 from top to bottom. Both the first bracket 32 ​​and the second bracket 35 are annular structures used to fix the stirring tank 33 and the holding tank 36, respectively. The stirring tank 33 is bolted to the inner wall of the first bracket 32. The stirring tank 33 is a cylindrical structure with an open top and a funnel-shaped bottom to facilitate concentrated ink discharge. A valve 34 is fixedly connected to the bottom outlet of the stirring tank 33. The valve 34 is manually or electrically controlled to control ink discharge. The holding tank 36 is bolted to the inner wall of the second bracket 35. The holding tank 36 is a cylindrical structure with an open top, and its inner diameter is larger than the outer diameter of the centrifugal filter cartridge 38. A centrifugal filter cartridge 38 is rotatably connected to the inner bottom of the holding tank 36 via bearings. The centrifugal filter cartridge 38 is a cylindrical mesh structure with an open top, and its side walls and bottom are provided with fine filter holes for filtering impurities in the ink. A valve 34 is located directly above the center of the centrifugal filter cartridge 38 to ensure that the ink discharged from the stirring tank 33 can accurately flow into the centrifugal filter cartridge 38. A gear ring 37 is welded and fixed to the middle of the outer wall of the centrifugal filter cartridge 38, and the gear ring 37 is coaxially arranged with the centrifugal filter cartridge 38. A fourth servo motor 39 is embedded and fixedly connected inside the side wall of the second bracket 35. The output shaft of the fourth servo motor 39 extends horizontally into the interior of the holding tank 36, and its end is fixedly connected to a drive gear 310. The drive gear 310 meshes with the gear ring 37, and the fourth servo motor 39 drives the drive gear 310 to rotate, which in turn drives the gear ring 37 and the centrifugal filter cartridge 38 to rotate at high speed, thereby achieving centrifugal filtration. The bottom of the holding container 36 has a perforation 311, which is evenly distributed along the outer edge of the centrifugal filter cartridge 38. The filtered ink flows through the perforation 311 into the collection container 312 below. The collection container 312 is movably placed on top of the base 1, directly below the holding container 36, and its shape is adapted to the bottom of the holding container 36 for easy collection and replacement.

[0021] Working Principle: When this environmentally friendly printing ink mixing and filtering device is in operation, the ink raw material to be mixed is first poured into the mixing tank 33. Then, the third servo motor 213 is started, driving the drive gear 214 to rotate. The drive gear 214, through meshing with the end face gear 23, drives the turntable 22 to rotate around the axis of the support rod 21 until the stirring impeller 211 moves directly above the mixing tank 33. Next, the first servo motor 28 is started, driving the lifting screw 25 to rotate. Due to the limiting effect of the limiting slide rod 26 on the nut block 27, the nut block 27 descends vertically along the lifting screw 25, thereby driving the long rod 29, rotating shaft 210, and stirring impeller 211 to descend synchronously until the stirring impeller 211 extends into the ink raw material in the mixing tank 33. After adjusting the immersion depth of the stirring impeller 211 according to the ink level, the first servo motor 28 is turned off. The second servo motor 212 is started, driving the rotating shaft 210 and the stirring impeller 211 to rotate at high speed, uniformly mixing and blending the ink raw materials in the mixing tank 33. During the mixing process, the rotation angle of the turntable 22 can be adjusted by controlling the start and stop of the third servo motor 213, so that the stirring impeller 211 makes circular motion inside the mixing tank 33, achieving all-round mixing and ensuring uniform ink blending. After the ink blending is completed, the second servo motor 212 is turned off, and the first servo motor 28 is started, causing the stirring impeller 211 to rise to the outside of the mixing tank 33. Then, the third servo motor 213 moves the stirring assembly 2 away from the top of the mixing tank 33. The valve 34 at the bottom of the mixing tank 33 is opened, and the blended ink flows out from the bottom outlet of the mixing tank 33 under the action of gravity, accurately falling into the centrifugal filter cartridge 38 inside the holding tank 36. The fourth servo motor 39 is activated, driving the drive gear 310 to rotate. The drive gear 310, through meshing with the gear ring 37, drives the centrifugal filter cartridge 38 to rotate at high speed. Under centrifugal force, the ink inside the centrifugal filter cartridge 38 is thrown against the cartridge wall, where impurities are filtered out through the fine pores at the bottom and the cartridge wall. The filtered, qualified ink flows into the holding container 36 and falls through the drain hole 311 at the bottom of the holding container 36 into the collection container 312 below for collection. After filtration is complete, the fourth servo motor 39 and valve 34 are closed, and the collection container 312 is removed to obtain the filtered environmentally friendly printing ink. Any remaining impurities inside the centrifugal filter cartridge 38 can be directly removed for cleaning; the operation is convenient and does not affect the continuity of subsequent operations.
