Description

Technical Field

[0001] This utility model belongs to the technical field of high-resolution color inkjet processing, specifically relating to a high-resolution color inkjet ink production device. Background Technology

[0002] Because high-resolution color inkjet printing requires the use of high-efficiency grinding equipment, even with materials of general quality, the pigments can be ground to the required ink quality using a high-efficiency grinding machine. Such conditions place extremely stringent requirements on water-based inks. High-resolution color inkjet inks require fine inkjet dots and vibrant colors, and the printheads must not dry out or clog even after prolonged exposure to air. This is a demand of the high-end domestic market. Therefore, the grinding stage in its manufacturing process must adopt a circulating grinding production method, and the particle size distribution curve must be concentrated to meet the set quality requirements. In particular, the grinding stage is difficult to achieve with traditional machines, making it challenging to achieve high dispersion of pigments.

After the improvement, the entire process is a closed production, which reduces dust pollution and improves the protection of people and the environment. It can be used for mass production to meet business needs. The cooling system avoids excessive evaporation due to excessive temperature during production, which will affect the quality.

[0024] like Figure 1 As shown, a coarse filter barrel 25 is provided with a coarse filter barrel screen fixing steel ring 26 inside, and a fine filter barrel 29 is provided with a fine filter barrel screen fixing steel ring 30 inside. The coarse filter barrel screen fixing steel ring 26 and the fine filter barrel screen fixing steel ring 30 are used to fix and connect the filter structures inside the coarse filter barrel 25 and the fine filter barrel 29, thereby facilitating coarse and fine filtration of the product.

[0025] like Figure 1 As shown, a pressure gauge 27 for the coarse filter barrel 25 is connected to the connecting pipe on the left side, and a pressure gauge 31 for the fine filter barrel 29 is installed on the connecting pipe on the left side. The pressure gauge 27 and the pressure gauge 31 for the fine filter barrel test the pressure of the product when it flows into the coarse filter barrel 25 and the fine filter barrel 29, respectively.

[0026] like Figure 1As shown, a coupling 7 is provided on the upper side of the stirring shaft 6, and a drive motor 9 is connected to the upper side of the coupling 7.

[0027] like Figure 1 As shown, a solvent inlet 3 is provided at the upper left end of the mixing tank 1, and a powder inlet 4 and a powder feeding platform 5 are provided at the upper right end of the mixing tank 1. The solvent inlet 3 and the powder inlet 4 are structures for feeding solvent and powder respectively.

[0028] like Figure 3 As shown, an outer connecting sleeve 34 is provided on the side of the stirring shaft 6. The outer connecting sleeve 34 is installed and connected to the stirring shaft 6 by screws. An outer connecting rod 37 is provided on the side of the outer connecting sleeve 34. A central connecting column 42 is provided inside the outer connecting rod 37. A side stirring mesh plate 35 is provided at the end of the central connecting column 42. A cleaning brush 36 is provided on the side of the side stirring mesh plate 35. A limiting movement groove 39 is provided on the side of the central connecting column 42. An internal limiting movement block 40 is provided in the limiting movement groove 39. The internal limiting movement block 40 and the central connecting column 42 are an integral structure. A connecting... A pressure limiting knob 38 is connected to the spring body 41 and the outer connecting rod body 37. When the stirring shaft 6 rotates, the side stirring screen 35 is thrown outward due to centrifugal force, causing the cleaning brush 36 to scrub the inner wall of the stirring tank 1. When the operation stops, the side stirring screen 35 will return to its original position due to the elastic stretching of the connecting spring body 41. The side stirring screen 35 facilitates the dispersion and fine flow of liquid. The pressure limiting knob 38 can block and limit the movement groove 39 so that the side stirring screen 35 will not move when the stirring shaft 6 rotates. After the improvement of this utility model, it is easier for users to clean the inner wall of the stirring tank, thereby effectively improving the practicality of the high-resolution color inkjet ink production device.

[0029] During operation, in the pre-dispersion stage: water-based raw materials and resin are introduced into the mixing tank 1 through the feed inlet 3. The motor 9 is started and rotates, driving the mixing shaft 6 and the serrated blades 2 through the coupling 7 for stirring. The bagged powder resin and color powder are placed on the powder feeding platform 5 and slowly fed through the powder feeding inlet 4. After the feeding is completed, high-speed pre-dispersion begins, and finally the material is discharged through the discharge outlet 8 to proceed to the next process. In the grinding stage: whiteboard ink is fed into the grinding chamber through the grinding chamber feed inlet 11 and enters the grinding chamber 12 through the grinding chamber ink guide 11. At this time, the inner rotor cylinder 14 rotates at high speed, driving the inner rotor 18 and the outer rotor 19 on the outer grinding cylinder 15 to form an interlaced and agitated motion, thereby driving the grinding balls. The grinding effect is achieved by the collision of the whiteboard ink. When the whiteboard ink flows along the structure of the grinding chamber 12 to the grinding ball separation zone 13, the grinding balls, being heavier than the ink, are thrown outwards by centrifugal force and move back into the grinding chamber 12. The whiteboard ink, under internal pressure, is filtered through the filter screen 16 and flows out of the grinding cylinder outlet 17. Because the collision of the grinding balls during the grinding process generates high heat, cooling water is introduced into the jacketed cooling 20 to cool the machine. Circulating grinding: At this time, the grinding cylinder outlet 17 is reconnected to the inlet 3 and fed into the mixing tank trough 1. The outlet 8 of the mixing tank trough 1 is connected to the grinding chamber inlet 11. The mixing tank trough 1 is opened... The drive motor 9 is connected and kept at a low to medium speed (approximately 600-900 RPM) to ensure uniform mixing of materials. The inner rotor cylinder 14 of the grinder rotates at high speed, driving the inner rotor 18 and the outer rotor 19 on the outer grinding cylinder 15 to form an alternating and agitating motion, causing the grinding balls to collide with the ink on the whiteboard, achieving the grinding effect. To begin operation: connect the material hopper 24 to the air pump 23 and the air source 21. Through the three-point pressure controller 22, the material is slowly pumped into the coarse filter hopper 25. At this point, the material passes through a 5μm filter screen and is fixed by the steel ring 26. After passing through the coarse filter, the material enters the fine filter hopper 29, where it passes through a 2μm filter screen. The filter screen is fixed by steel ring 30. After fine filtration, it is finally introduced into packaging 33. To finish the operation: adjust the three-point combined pressure controller 22 to increase the pressure. At this time, the air pump 23 will quickly pump in air to discharge the residual ink from the two filter barrels through packaging 33. After emptying, open the discharge valve 28 of the coarse filter barrel and the discharge valve 32 of the fine filter barrel to discharge the residual material. If the pressure of the pressure gauge 27 of the coarse filter barrel or the pressure gauge 31 of the fine filter barrel is too high at this time, it means that the filter element is saturated. Turn off the air source 21 to stop the air pump 23 from working. Open the discharge valve 28 of the coarse filter barrel and the discharge valve 32 of the fine filter barrel to discharge the residual material back into the material barrel 24. After emptying, replace the filter element.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
