[0002] Water-based ink, water-based ink is referred to as water-based ink, and flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. Water-based ink is particularly suitable for packaging and printing products with strict hygiene requirements such as tobacco, alcohol, food, beverages, medicines, children's toys, etc.

[0003] According to the patent document: CN111330692A, a water-based ink preparation grinding and dispersing processing technology disclosed includes a tank assembly, a grinding mechanism, a screening mechanism, a first motor, a feed hopper, a second motor and a collecting bag. The tank assembly is provided with a grinding mechanism inside, the upper end of the grinding mechanism is connected to the first motor, and the first motor is fixed to the top of the tank assembly through a fixing rod, a screening mechanism is provided directly below the grinding mechanism, one side of the screening mechanism is connected to the second motor, and the second motor is fixed to the outer wall of the tank assembly, the feed hopper is installed on the top of the grinding mechanism, the outer wall and the bottom center of the tank assembly are both provided with a collecting bag, and the outer wall of the steel structure shell is welded with a support frame. According to the present invention, the grinding process is more refined, the screening mechanism has high continuous operation, and there will be no situation where graphite blocks the sieve holes and a large amount of graphite accumulates. At the same time, the grinding mechanism and the screening mechanism are placed in the same shell, which effectively reduces the energy loss;

[0004] Grinding and dispersing devices play a vital role in the modern printing industry. Their main function is to grind materials such as inks and pigments to the required fineness to ensure the texture and color effect of printed products. However, in this process, the grinding and dispersing device needs to be screened through a filter after completing the grinding. The main purpose of this step is to screen out the ink that is not ground sufficiently to ensure the quality of the final product. However, in actual operation, this step brings a series of problems. After the screened ink is collected, in order to maintain the continuity of the production line and the consistency of the product, these inks often need to be re-grinded, but the existing operation mode requires staff to manually pour the screened ink back into the grinding device, which undoubtedly increases the complexity of the operation. Moreover, due to the uncertainty of human operation, it may also lead to waste of ink and degradation of quality. Summary of the invention

[0040] Step 4: Grinding and dispersing.

The opposite sides of the two slide plates 1111 are provided with slides 1113, and the grinding top plate 12 includes a grinding top plate shell 121, and the inner wall of the grinding top plate shell 121 is fixedly connected with a grinding top plate The main body 122, the top of the grinding top plate main body 122 is fixedly connected with a grinding top plate rotating shaft 126, the outer wall of the grinding top plate rotating shaft 126 is rotatably connected to the inner wall of the grinding top plate outer plate 117, the outer wall bottom of the grinding top plate rotating shaft 126 is fixedly connected with a plurality of first tooth blocks 124 in an annular array, the outer walls of the plurality of first tooth blocks 124 are meshed with the outer wall of the worm 1110, the top annular array of the grinding top plate rotating shaft 126 is fixedly connected with a plurality of second tooth blocks 125, the top of the grinding top plate main body 122 is provided with a feeding trough 123 that runs through the bottom of the grinding top plate main body 122, and the two pressing material control mechanisms 13 each include a rotating rod connecting block 131, the bottoms of the two rotating rod connecting blocks 131 are respectively fixedly connected to the outer plate 117 of the grinding top plate. On both sides of the top of 17, the inner walls of the two rotating rod connecting blocks 131 are rotatably connected with rotating rods 132, the opposite ends of the two rotating rods 132 are fixedly connected with gears 133, the outer walls of the two gears 133 are respectively meshed with the top sides of the plurality of second tooth blocks 125, the opposite ends of the two rotating rods 132 are fixedly connected with rotating disks 134, the opposite surfaces of the two rotating disks 134 are fixedly connected with rotating disk rotating rods 135, the outer walls of the two rotating disk rotating rods 135 are slidably connected with elliptical push-pull plates 136, the bottoms of the two elliptical push-pull plates 136 are fixedly connected with inverted Z-shaped connecting rods 137, the opposite surfaces of the two inverted Z-shaped connecting rods 137 are fixedly connected with sliders 138, and the bottoms of the two sliders 138 are fixedly connected with springs 139.The outer walls of the two sliders 138 are respectively slidably connected to the inner walls of the slide slots 1113 opened on the opposite surfaces of the two slide slot plates 1111, the bottoms of the two springs 139 are respectively fixedly connected to the bottoms of the inner walls of the two slide slots 1113, the bottoms of the two inverted Z-shaped connecting rods 137 are fixedly connected to the pressure plate 1310, and the bottom of the pressure plate 1310 is aligned with the inner wall of the filter plate 114;

[0044] When grinding and dispersing processing is required, the raw materials to be processed are first poured into the grinding disc 1 through the feed port 2, and the raw materials first enter the feed slot 123 of the grinding top disc 12, and then during the grinding process, the grinding top disc 12 starts to rotate;

[0045] After the motor 119 is started, it drives the worm 1110 to rotate. Since the outer wall of the worm 1110 is meshed with the first tooth block 124 on the outer wall of the grinding top plate shaft 126, the grinding top plate shaft 126 will rotate accordingly, thereby driving the grinding top plate body 122 to rotate at a high speed. During the rotation of the grinding top plate 12, its bottom contacts the sloped disc surface of the grinding bottom plate 113 to grind and disperse. The ground material is filtered through the filter plate 114 to remove the particles that are not fully ground, ensuring that the particle size of the final product meets the requirements;

[0046] At the same time, the second tooth block 125 on the top of the grinding top plate shaft 126 will drive the gears 133 on both sides to rotate, and the gears 133 will drive the rotating rod 132 and the rotating disk 134 to rotate. As the rotating disk 134 rotates, the elliptical push-pull plate 136 on the rotating disk rotating rod 135 will reciprocate. Due to the elastic force of the spring 139, the inverted Z-shaped connecting rod 137 drives the pressure plate 1310 to reciprocate up and down.

[0047] In this way, the pressing plate 1310 will continuously press and release the filter plate 114 during the grinding process, and further grind the particles remaining on the filter plate 114 that have not been fully ground by pressing, thereby improving the grinding efficiency and ensuring the uniformity and fineness of the material grinding;

[0048] Under the dual effects of the high-speed rotation of the grinding top plate 12 and the up-and-down reciprocating motion of the pressure plate 1310, the material is fully ground and dispersed in the grinding plate 1, and finally, the material that is evenly ground and has a suitable particle size is collected in the receiving plate 112;

[0049] When the grinding process is finished, the user only needs to turn off the motor 119 and remove the receiving tray 112 from the bottom plate 111 to obtain the prepared water-based ink. The entire operation process is simple, convenient and easy to master.

[0050] like Figure 8As shown, the feed port 2 includes a feed pipe 21, the outer wall of the feed pipe 21 is fixedly connected to the inner wall of the feed trough 123 opened by the grinding top plate main body 122, the top of the outer wall of the feed pipe 21 is rotatably connected with a feed hopper 22, the bottom of the outer wall of the feed hopper 22 is fixedly connected with a third tooth block connecting disk 23, the bottom annular array of the third tooth block connecting disk 23 is fixedly connected with a plurality of third tooth blocks 24, the bottoms of both sides of the plurality of third tooth blocks 24 are respectively meshed with the outer walls of the two gears 133, the top of the inner wall of the feed funnel 22 is fixedly connected with an auger rod connecting rod 25, the top of the auger rod connecting rod 25 is fixedly connected with an auger rod 26, the top of the feed funnel 22 is rotatably connected with a top feed funnel 28, the two sides of the outer wall of the top feed funnel 28 are respectively fixedly connected with top feed funnel connecting rods 27, and the bottoms of the two top feed funnel connecting rods 27 are respectively fixedly connected to the two sides of the outer wall of the grinding top plate outer plate 117;

[0051] When grinding and dispersing processing is required, the raw materials to be processed are poured into the top feeding funnel 28 through the top feeding funnel 28, and the raw materials flow into the feeding funnel 22 along the channel and finally enter the feeding slot 123 of the grinding top plate 12. In this process, since the third tooth block connecting plate 23 fixedly connected to the bottom of the feeding funnel 22 and the plurality of third tooth blocks 24 in the annular array thereon are meshed with the outer wall of the gear 133, when the grinding top plate 12 starts to rotate, it will drive the feeding funnel 22 to rotate synchronously;

[0052] As the feed hopper 22 rotates, the auger rod connecting rod 25 fixed on the top of the inner wall thereof and the auger rod 26 thereon also rotate accordingly. The rotation of the auger rod 26 can push the raw material downward in the feed hopper 22, ensuring that the raw material can smoothly enter the feed trough 123, and then be ground and dispersed by the grinding top plate 12;

[0053] This design not only improves the efficiency of raw materials entering the grinding top plate 12, but also avoids the clogging or accumulation of raw materials in the feeding funnel 22, thereby ensuring the smooth progress of the grinding process.

[0054] Working principle of the present invention: when it is necessary to carry out grinding and dispersing processing, first pour the raw material to be processed into the grinding disc 1 through the feed port 2, and the raw material first enters the feed slot 123 of the grinding top disc 12, and then during the grinding process, the grinding top disc 12 starts to rotate, and after the motor 119 is started, it drives the worm 1110 to rotate. Since the outer wall of the worm 1110 is meshed with the first tooth block 124 on the outer wall of the grinding top disc shaft 126, the grinding top disc shaft 126 will rotate accordingly, thereby driving the grinding top disc body 122 to rotate at high speed. During the rotation of the grinding top disc 12, its bottom contacts the sloped disc surface of the grinding bottom disc 113 for grinding and dispersing. The ground material is filtered through the filter disc 114 to remove the particles that are not fully ground, ensuring that the particle size of the final product meets the requirements. At the same time, the second tooth block 125 on the top of the grinding top disc shaft 126 will drive the gears 133 on both sides to rotate, and the gears 133 will drive the rotating rod 132 and the rotating disc 134 to rotate. As the turntable 134 rotates, the elliptical push-pull plate 136 on the turntable rotating rod 135 will reciprocate. Due to the elastic force of the spring 139, the inverted Z-shaped connecting rod 137 drives the pressure plate 1310 to reciprocate up and down. In this way, the pressure plate 1310 will continuously press and release the filter plate 114 during the grinding process, and further grind the particles that are not fully ground remaining on the filter plate 114 by pressing, thereby improving the grinding efficiency and ensuring the uniformity and fineness of the material grinding. Under the dual effects of the high-speed rotation of the grinding top plate 12 and the up and down reciprocating movement of the pressure plate 1310, the material is fully ground and dispersed in the grinding plate 1. Finally, the material that is evenly ground and of suitable particle size is collected in the receiving plate 112. When the grinding process is completed, the user only needs to turn off the motor 119 and remove the receiving plate 112 from the bottom plate 111 to obtain the prepared water-based ink. The entire operation process is simple and convenient and easy to master.

[0055] When grinding and dispersing processing is required, the raw materials to be processed are poured into the top feeding funnel 28 through the top feeding funnel 28, and the raw materials will flow into the feeding funnel 22 along the channel and finally enter the feeding trough 123 of the grinding top plate 12. In this process, since the third tooth block connecting plate 23 fixedly connected to the bottom of the feeding funnel 22 and several third tooth blocks 24 in the annular array thereon are meshed with the outer wall of the gear 133, when the grinding top plate 12 starts to rotate, it will drive the feeding funnel 22 to rotate synchronously. As the feeding funnel 22 rotates, the auger rod connecting rod 25 fixed on the top of its inner wall and the auger rod 26 thereon will also rotate accordingly. The rotation of the auger rod 26 can push the raw materials to move downward in the feeding funnel 22, ensuring that the raw materials can smoothly enter the feeding trough 123, and then be ground and dispersed by the grinding top plate 12. This design not only improves the efficiency of the raw materials entering the grinding top plate 12, but also avoids the blockage or accumulation of raw materials in the feeding funnel 22, thereby ensuring the smooth progress of the grinding process.
