[0002] Environmentally friendly printing inks are printing pigments that cause less environmental pollution and are suitable for various printed materials, such as brochures, posters, and instruction manuals.
[0003] In the production process of environmentally friendly printing inks, binders, pigments, and additives need to be mixed in a certain proportion. After mixing, the environmentally friendly printing inks need to be placed in a storage container and stored in a cool, dry environment. When the ink is used, it should be taken out of the storage container.
[0004] During long-term storage after ink mixing, the physical or chemical changes in the ink components due to gravity can easily lead to the formation of sediments at the bottom of the container, resulting in reduced ink fluidity and decreased ink quality when used.
[0005] Therefore, this utility model provides an environmentally friendly printing ink mixing and storage device. Summary of the Invention

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 4As shown in the figure, an environmentally friendly printing ink mixing and storage device according to an embodiment of the present invention includes a mixing box 1. The mixing box 1 has an inlet 10 at the top and an outlet 11 at the bottom. A motor 12 is installed on the top of the mixing box 1, and the output end of the motor 12 passes through the top of the mixing box 1. A rotating shaft 13 is fixedly connected to the output end of the motor 12. Two stirring blades 14 are fixedly connected to the middle of the rotating shaft 13 and are arranged opposite to each other. A rolling roller 15 is rotatably connected to the middle of the rotating shaft 13 and is located at the bottom of the mixing box 1. A scraper 16 is fixedly connected to the middle of the rotating shaft 13 and is arranged opposite to the rolling roller 15. A positioning component 4 is provided on the outer wall of the mixing box 1. During operation, the mixing box 1 is installed on the positioning component 4, and the raw materials for mixing printing ink are placed inside the mixing box 1 through the inlet 10 in a certain proportion for storage. At this time, the motor 12 is powered on and turned on, so that its output end drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the stirring blades 14, the rolling roller 15 and the scraper 16 to rotate. The plate 16 rotates inside the mixing chamber 1, and the two stirring blades 14 agitate the raw materials. While the roller 15 rotates inside the mixing chamber 1 with the rotating shaft 13, it also rotates at the bottom of the mixing chamber 1, crushing the raw materials at the bottom of the mixing chamber 1. The scraper 16 rotates with the rotating shaft 13 to continuously scrape the raw materials at the bottom. When using ink, the outlet 11 is opened, allowing the uniformly mixed ink to flow out from the outlet 11 and be taken out for use. Through the above structure, the cooperation between the roller 15 and the scraper 16 can make the printing ink uniformly mixed inside the mixing chamber 1, while reducing the problem of ink raw materials depositing and agglomerating during storage. It can continuously push and scrape the ink to flow inside the mixing chamber 1, reduce the problem of ink depositing at the bottom of the mixing chamber 1, reduce the formation of sediment layer due to long-term ink stagnation, maintain the overall fluidity and stability of the ink in the mixing chamber 1, and make the ink evenly distributed in all corners of the mixing chamber 1, reducing the stratification of ink due to density differences during storage.
[0024] like Figures 1 to 4As shown, a cavity 2 is provided in the middle of the rotating shaft 13. A water inlet pipe 21 is rotatably connected to the bottom of the rotating shaft 13. The middle of the water inlet pipe 21 passes through the bottom of the mixing box 1. A water pump 22 is fixedly connected to the end of the water inlet pipe 21. A water outlet pipe 23 is fixedly connected to the middle of the water pump 22. Multiple nozzles 24 are fixedly connected to the middle of the rotating shaft 13. During operation, after the printing ink is used up, the water source pipe is connected to the end of the water outlet pipe 23, and the water pump 22 is turned on, so that the water flows through the water pump 22 into the water inlet pipe 21. Water is discharged into the cavity 2 through high pressure and sprayed from the center of multiple nozzles 24. At the same time, the motor 12 rotates to spray water onto various positions of the mixing box 1. Through the above-mentioned structure, the nozzles 24 can continuously clean the inner wall of the mixing box 1, reducing the amount of ink adhering to the inner wall of the mixing box 1 after storage, reducing the problems of ink residue and drying and clumping inside the mixing box 1. Regularly cleaning the inside of the mixing box 1 can extend the service life of the mixing box 1 and achieve comprehensive cleaning of the inside of the mixing box 1.
[0025] like Figures 2 to 3 As shown, a sleeve 3 is rotatably connected to the middle of the rotating shaft 13. The sleeve 3 is located outside the rotating shaft 13, and multiple through holes 31 are opened in the middle of the sleeve 3. The multiple through holes 31 are aligned with the positions of multiple nozzles 24. During operation, when the nozzles 24 are not in use, the sleeve 3 is rotated to move the multiple through holes 31 away from the multiple nozzles 24. When the rotating shaft 13 rotates, the sleeve 3 rotates simultaneously with the rotating shaft 13. When the nozzles 24 clean the inside of the mixing tank 1, the sleeve 3 is rotated again to make the multiple through holes 31 coincide with the positions of the nozzles 24, so that when the water flows out from the nozzles 24, it flows into the mixing tank 1 through the through holes 31. The above structure can reduce the amount of ink entering the inside of the nozzles 24 during the mixing and storage process, reduce the accumulation of ink or internal particulate impurities inside the nozzles 24, effectively reduce the problem of ink accumulation inside the nozzles 24 causing blockage, and quickly expose the nozzles 24 for cleaning when needed, thereby protecting the nozzles 24.
[0026] like Figures 1 to 4 As shown, the positioning component 4 includes a base plate 41, which is located at the bottom of the mixing box 1. Two fixing brackets 42 are fixedly connected to the top of the base plate 41, and fixing blocks 43 are fixedly connected to the ends of the two fixing brackets 42. A fixing plate 44 is fixedly connected to the outer wall of the mixing box 1. The fixing plate 44 is installed in the middle of the fixing block 43. During operation, when the mixing box 1 is placed, the fixing plate 44 is first aligned with the middle of the fixing block 43, and the fixing plate 44 is inserted into the middle of the fixing block 43. It is then supported and positioned by the fixing brackets 42. The above structure can effectively increase the stability and accuracy of the mixing box 1 during the mixing process, reduce the movement and tilting of the mixing box 1 during the mixing process, and thus maintain the quality of the printing ink mixing.
[0027] like Figure 2 and Figure 4As shown, a filter plate 5 is fixed to the inner wall of the mixing chamber 1, and a rotating shaft 13 passes through the middle of the filter plate 5. During operation, when the raw material enters the mixing chamber 1, it is filtered by the filter plate 5 to pre-treat the raw material. After being stirred by the stirring blade 14, it enters the bottom of the mixing chamber 1 through the filter plate 5. The above structure can effectively screen and disperse the ink, so that the pigments and resin raw materials in the ink are evenly mixed together. It can also filter out impurities and particles in the ink, reducing the damage caused by impurities and particles in the ink entering the printing press.
[0028] like Figure 4 As shown, a support rod 6 is fixedly connected to the middle of the rotating shaft 13, and a brush bristle 61 is fixedly connected to the middle of the support rod 6. The ends of the brush bristle 61 are in contact with the bottom of the filter plate 5. During operation, when the rotating shaft 13 rotates, it drives the support rod 6 to rotate at the same time. The support rod 6 causes the brush bristle 61 to clean the bottom of the filter plate 5. The above structure can effectively reduce the accumulation of raw materials on the surface of the filter plate 5, reduce the accumulation of raw materials on the surface of the filter plate 5 and the blockage caused by the accumulation of raw materials on the surface of the filter plate 5, effectively clean the surface of the filter plate 5, and reduce the accumulation of ink on the surface of the filter plate 5 and the wear caused by the accumulation.
[0029] like Figure 1 As shown, a transparent plate 7 is provided in the middle of the mixing box 1. The transparent plate 7 is located at the bottom of the fixed plate 44. During operation, when the ink raw materials are stored inside the mixing box 1, the amount of ink used inside the mixing box 1 can be directly observed through the transparent plate 7. The above structure allows direct observation of the amount of ink used inside the mixing box 1, which can effectively reduce the operation time of opening the mixing box 1.
[0030] During operation, the mixing chamber 1 is installed on the positioning assembly 4. The raw materials for mixing printing ink are placed inside the mixing chamber 1 through the feed inlet 10 in a certain proportion for storage. At this time, the motor 12 is powered on and turned on, so that its output end drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the stirring blades 14, the pressing rollers 15 and the scraper 16 to rotate simultaneously inside the mixing chamber 1. The two stirring blades 14 agitate the raw materials. When the pressing rollers 15 rotate inside the mixing chamber 1 with the rotating shaft 13, they themselves are at the bottom of the mixing chamber 1. The rotating mechanism crushes the raw materials at the bottom of the mixing chamber 1. The scraper 16, rotating with the rotating shaft 13, continuously scrapes the raw materials at the bottom. When ink is used, the outlet 11 is opened, allowing the evenly mixed ink to flow out and be used. After the printing ink is used up, the water supply pipe is connected to the end of the water outlet pipe 23, and the water pump 22 is turned on, allowing water to flow through the pump 22 into the water inlet pipe 21. The water is then discharged into the cavity 2 through the water inlet pipe 21, and high pressure forces the water to spray out from the center of multiple nozzles 24. Simultaneously, the motor 12 rotates to spray water onto various positions of the mixing tank 1. When the nozzles 24 are not in use, the sleeve 3 is rotated to move the multiple through holes 31 away from the multiple nozzles 24. When the rotating shaft 13 rotates, the sleeve 3 rotates simultaneously with the rotating shaft 13. When the nozzles 24 clean the inside of the mixing tank 1, the sleeve 3 is rotated again to make the multiple through holes 31 coincide with the position of the nozzles 24, so that when the water flows out from the nozzles 24, it flows into the mixing tank 1 through the through holes 31. When the mixing tank 1 is placed, the fixing plate 44 is first aligned with the middle of the fixing block 43. The fixing plate 44 is inserted into the middle of the fixing block 43 and supported and positioned by the fixing frame 42. When the raw material enters the mixing box 1, it is filtered by the filter plate 5 and pre-treated. After being stirred by the stirring blade 14, it enters the bottom of the mixing box 1 through the filter plate 5. When the rotating shaft 13 rotates, it drives the support rod 6 to rotate. The support rod 6 causes the brush 61 to clean the bottom of the filter plate 5. When the ink raw material is stored in the mixing box 1, the amount of ink used in the mixing box 1 can be directly observed through the transparent plate 7.
