Description

Technical Field

[0001] This utility model relates to the field of water-based ink emulsification technology, specifically to an emulsification mechanism for water-based inks. Background Technology

[0002] With the popularization of environmentally friendly printing concepts, water-based inks are widely used in packaging printing, book printing and other fields due to their low VOC emissions and environmentally friendly characteristics. As the core process in the production of water-based inks, the emulsification process directly determines the ink's dispersion uniformity, pigment particle size distribution and storage stability.

[0003] Existing water-based ink emulsification equipment mostly relies on unidirectional rotational stirring to achieve emulsification. However, unidirectional stirring easily causes the ink to form a stable annular flow field, which can easily create shear dead angles inside the flow field. Large pigment agglomerates are difficult to be effectively dispersed, directly affecting the color consistency of printed products. Furthermore, the stirring components of traditional equipment are at a fixed height. At low liquid levels, the stirring blades are partially exposed, which can easily generate air bubbles and result in insufficient shear coverage. At high liquid levels, the blades are covered by deep ink, and the surface ink forms a floating oil layer due to insufficient shear force, further aggravating uneven emulsification.

[0004] Therefore, we propose an emulsification mechanism for water-based inks to address the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model: The purpose of this invention is to provide an emulsification mechanism for water-based inks to solve the problems currently existing in the market as described in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: an emulsification mechanism for water-based inks, comprising a barrel body, a cover body fitted on the upper end of the barrel body, a bracket fixed in the middle of the upper end of the cover body, a hydraulic cylinder mounted on the bracket, and a housing fixedly connected to the output end of the hydraulic cylinder; The box body is equipped with a first rotating rod and a second rotating rod through bearings. The second rotating rod is sleeved on the outside of the first rotating rod. A driving component is installed between the first rotating rod and the second rotating rod. A stirring rod is installed at the lower end of the first rotating rod, and a scraper is installed at the lower end of the second rotating rod.

[0007] Furthermore, sliders are fixed on both the left and right sides of the box, and the box is mounted on the bracket by sliding up and down via the sliders.

[0008] The above technical solution enables the box to move stably up and down on the support after being subjected to force by the slider.

[0009] Furthermore, the driving component includes a driving bevel gear mounted on the housing via bearings. The upper and lower ends of the driving bevel gear are respectively meshed with a driven bevel gear one and a driven bevel gear two. The driven bevel gear one is fixedly sleeved on the outer side of the upper end of the first rotating rod, and the driven bevel gear two is fixedly sleeved on the outer side of the second rotating rod.

[0010] The above technical solution enables the driven bevel gear 1 and driven bevel gear 2 to rotate respectively after the motor drives the active bevel gear to rotate, and the driven bevel gear 1 and driven bevel gear 2 rotate in opposite directions.

[0011] Furthermore, the stirring rods are evenly distributed at the lower end of the first rotating rod, and several horizontal spikes are installed on both sides of the stirring rods.

[0012] The above technical solution enables the spikes to penetrate pigment agglomerates in the ink during rotation, cutting large agglomerates into small particles, while breaking down the viscous resistance inside the ink, accelerating the mixing of various components, and improving the emulsification effect.

[0013] Furthermore, the scraper rods are arranged at equal angles about the center of the second rotating rod, and each scraper rod has a horizontal bar fixed at equal intervals on its side, and several vertical spikes are installed on the upper and lower sides of the horizontal bar.

[0014] The above technical solution enables the scraper to remove the ink adhering to the inner wall during rotation.

[0015] Furthermore, the crossbars and stirring rods are arranged in an alternating pattern.

[0016] The above technical solution breaks the unidirectional annular flow field that is easily formed when a single stirring rod rotates, thereby improving the emulsification uniformity.

[0017] 3. Beneficial effects: Compared with the prior art, the emulsification mechanism of this utility model, using the technical solution provided by this utility model, drives two sets of rotating rods to rotate synchronously in opposite directions through a driving component, realizing simultaneous stirring and wall scraping. At the same time, the relative position of the two rods and the liquid surface can be adjusted to promote the ink to form an upward and downward convection, achieving uniform emulsification. The specific details are as follows: After the motor at the end of the active bevel gear is started, it drives the active bevel gear to rotate. Since the upper and lower ends of the active bevel gear mesh with the driven bevel gear one and the driven bevel gear two respectively, the stirring rod on the first rotating rod and the cross bar on the second rotating rod rotate in opposite directions. This prevents the ink from forming a stable flow field due to unidirectional stirring, improves the emulsification uniformity, and the horizontal spikes on both sides of the stirring rod can penetrate the pigment agglomerates in the ink, cut the large agglomerates into small particles, break the viscous resistance inside the ink, accelerate the mixing of the components, and improve the emulsification effect. When the second rotating rod rotates, the scrapers distributed at equal angles on the side rotate closely against the inner wall of the barrel, directly scraping off the ink residue adhering to the barrel wall, thus preventing subsequent water-based inks from sticking to the wall due to standing or stirring, which would affect the purity of subsequent batches of ink. After the hydraulic cylinder is started, it drives the double rotating rods to move up and down steadily, adjusts the relative position of the double rods and the liquid surface, balances the shear strength gradient of high resistance in the deep layer and low resistance in the surface layer, breaks the dead angle of the unidirectional flow field, and promotes the ink to form vertical convection to achieve uniform emulsification.

[0024] Please see Figure 1-4 An emulsification mechanism for water-based inks includes a barrel 1, a cover 2 fitted to the upper end of the barrel 1, a bracket 3 fixed to the middle of the upper end of the cover 2, a hydraulic cylinder 4 mounted on the bracket 3, and a housing 5 fixedly connected to the output end of the hydraulic cylinder 4; a first rotating rod 7 and a second rotating rod 8 are mounted inside the housing 5 via bearings, the second rotating rod 8 is sleeved on the outside of the first rotating rod 7, and a driving component 6 is installed between the first rotating rod 7 and the second rotating rod 8; a stirring rod 9 is mounted at the lower end of the first rotating rod 7, and a scraper rod 10 is mounted at the lower end of the second rotating rod 8; the driving component 6 includes a drive bevel gear 61 mounted on the housing 5 via bearings, the main... The upper and lower ends of the moving bevel gear 61 are respectively meshed with driven bevel gear 62 and driven bevel gear 63. Driven bevel gear 62 is fixedly sleeved on the outer side of the upper end of the first rotating rod 7, and driven bevel gear 63 is fixedly sleeved on the outer side of the second rotating rod 8. The stirring rods 9 are evenly distributed at the lower end of the first rotating rod 7, and several horizontal spikes 91 are installed on both sides of the stirring rods 9. The scraper rods 10 are distributed at equal angles about the center of the second rotating rod 8, and each scraper rod 10 has a horizontal bar 101 fixed at equal intervals on its side. Several vertical spikes 102 are installed on both the upper and lower sides of the horizontal bar 101. The horizontal bars 101 and the stirring rods 9 are arranged alternately. The motor at the end of the active bevel gear 61 is started, driving the active bevel gear 61 to rotate. Since the upper and lower ends of the active bevel gear 61 are respectively engaged with the driven bevel gear 62 and the driven bevel gear 63, the driven bevel gear 62 and the driven bevel gear 63 are driven to rotate synchronously in opposite directions. This causes the stirring rod 9 on the first rotating rod 7 and the cross bar 101 on the second rotating rod 8 to rotate in opposite directions, preventing the ink from forming a stable flow field due to unidirectional stirring, improving the emulsification uniformity. In addition, the horizontal spikes 91 on both sides of the stirring rod 9 can penetrate the pigment agglomerates in the ink, cutting large agglomerates into small particles, while breaking the viscous resistance inside the ink, accelerating the mixing of various components, and improving the emulsification effect. When the second rotating rod 8 rotates, the scraper 10, which is distributed at equal angles on the side, rotates close to the inner wall of the barrel 1, directly scraping off the ink residue attached to the barrel wall, preventing the water-based ink from sticking to the wall due to standing or stirring, which would affect the purity of subsequent batches of ink. Slider 51 is fixed on both the left and right sides of the box 5, and the box 5 is mounted on the bracket 3 by sliding up and down through the slider 51. Start hydraulic cylinder 4 to drive the double rotating rods to move up and down steadily, adjust the relative position of the double rods and the liquid surface, balance the shear strength gradient of high resistance in the deep layer and low resistance in the surface layer, break the dead angle of the unidirectional flow field, and promote the ink to form vertical convection to achieve uniform emulsification.

[0025] Working principle: When using this emulsification mechanism for water-based inks, such as Figure 1-4 As shown, after the material is put into the barrel 1, the motor at the end of the active bevel gear 61 is started. The drive component 6 drives the stirring rod 9 on the first rotating rod 7 and the crossbar 101 on the second rotating rod 8 to rotate in opposite directions. This prevents the ink from forming a stable flow field due to unidirectional stirring, improves the emulsification uniformity, and the horizontal spikes 91 on both sides of the stirring rod 9 can penetrate the pigment agglomerates in the ink, cutting large agglomerates into small particles. At the same time, it breaks the viscous resistance inside the ink, accelerates the mixing of various components, and improves the emulsification effect. Meanwhile, the second rotating rod 8 drives the scraper 10 to scrape off the ink residue attached to the barrel wall, preventing the subsequent water-based ink from sticking to the wall due to standing or stirring, which would affect the purity of subsequent batches of ink. When the hydraulic cylinder 4 is started, the two rotating rods move up and down stably, adjusting the relative position of the two rods and the liquid surface, balancing the shear strength gradient of the deep layer with high resistance and the surface layer with low resistance, breaking the dead angle of the unidirectional flow field, and pushing the ink to form an upward and downward convection to achieve uniform emulsification.
