Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] Please see Figures 1 to 5 and Figures 9 to 11 This utility model provides a technical solution:

[0040] A mixing device for producing water-based ink materials includes: a mixing tank 1, a settling tank 23, a discharge pipe 29, a feed pipe 30, and a rotary spray nozzle 31;

[0041] The bottom of the mixing tank 1 is fixedly installed on the top of the settling tank 23, and the bottom of the mixing tank 1 is connected to the top of the settling tank 23.

[0042] One end of the feed pipe 30 passes through the mixing tank 1 and extends to the bottom center of its interior. This end of the feed pipe 30 is connected to the rotary spray nozzle 31.

[0043] The discharge pipe 29 is located at the bottom of the settling box 23 and is connected to the interior of the settling box 23;

[0044] The water-based ink is conveyed to the rotary spray nozzle 31 via the feed pipe 30. After being dispersed by rotation, it enters the mixing tank 1 for stirring. The mixed liquid is then placed in the settling tank 23 for settling treatment and finally discharged via the discharge pipe 29.

[0045] The mixing tank 1 adopts a double-layer tank structure, with a PTC heater 17 installed between the inner wall of the outer layer and the outer wall of the inner layer. This PTC heater 17 can precisely and uniformly heat the ink inside the mixing tank 1. Combined with a temperature sensor 18 fixed to the outer wall for real-time temperature monitoring inside the mixing tank 1, this forms a "heating-monitoring" intelligent temperature control closed-loop system. This avoids viscosity instability caused by excessively high or low temperatures, improving the uniformity and stability of the mixing effect. A drive motor 14 and a planetary reducer 15 are fixedly installed above the top plate 12. The power output from the drive motor 14 is reduced in speed and increased in output torque by the planetary reducer 15 before being stably transmitted to the stirring device 2 located inside the mixing tank 1, providing a stable and powerful power source for the stirring device 2. In addition, multiple nozzles 13 are arranged circumferentially around the bottom of the top plate 12. After the mixing operation is completed, nozzle 13 can spray cleaning liquid or thinner onto the inner wall of the mixing tank 1 to achieve automated preliminary cleaning of residual ink on the inner wall of the tank, improving the cleaning efficiency and convenience of the equipment, reducing the intensity of manual cleaning and avoiding cross-contamination. The drive motor 14 is externally fixedly equipped with a motor protective shell 8. The cast aluminum shell of the drive motor 14 has axial heat dissipation fins, an integrated centrifugal fan at the tail, and a built-in thermistor to monitor the winding temperature for overload protection. The motor protective shell 8 forms a physical barrier to effectively prevent the intrusion of water-based ink, cleaning thinner or water mist, and dust in the mixing environment, avoiding motor failure caused by insulation degradation, short circuit or corrosion.

[0046] The stirring device 2 consists of a first rotating shaft 3, a rotating disk 4, an upper stirring cylinder 10, and lower stirring blades 11. The differential rotation of the stirring device 2 is achieved through the dual output shaft design of the planetary reducer 15 to realize power distribution and steering control: the top end of the first rotating shaft 3 passes through the top plate 12 of the equipment and is coaxially fixedly connected to one of the output ends of the planetary reducer 15 to realize stable power transmission; the rotating disk 4 is radially fixedly installed in the middle of the shaft of the first rotating shaft 3, and the upper stirring cylinder 10 is sleeved and fixed on the shaft section of the first rotating shaft 3 located below the rotating disk 4, which can shear and mix the upper layer of ink in the box; several lower stirring blades 11 are evenly distributed circumferentially at the bottom of the first rotating shaft 3, which can penetrate into the bottom area of ​​the mixing box 1 to fully disperse the bottom layer of ink. The input end of the planetary reducer 15 is connected to the drive motor 14. Internally, it forms two output paths with different transmission ratios through a sun gear, planetary gear set, and double gear ring structure. One output shaft drives the upper stirring drum 10 with a small transmission ratio and high output speed, driving the upper stirring drum 10 to rotate clockwise at high speed to enhance the shearing effect and break ink bubbles. The other output shaft is connected to the transmission structure of the lower stirring blade 11 through the planetary gear set, with a large transmission ratio and low output speed, driving the lower stirring blade 11 to rotate counterclockwise at low speed, which can avoid excessive breakage of pigment particles and form vertical convection.

[0047] The rotating disk 4 is radially fixedly connected to the first rotating shaft 3 and rotates synchronously with it. A supporting boss 7 is provided circumferentially on the top of the rotating disk 4. This supporting boss 7 is used to support and fix the connecting beam 5. A guide groove is formed inside the supporting boss 7 for the connecting beam 5 to slide. A cleaning scraper 6 is fixedly connected to the outer end of the connecting beam 5. The cutting edge of the cleaning scraper 6 is in close contact with the inner wall of the mixing tank 1 and can slide with rotation, scraping away residual ink and sediment from the wall surface in real time to prevent scaling. A bubble-piercing cone 9 is fixedly installed on the inner surface of the cleaning scraper 6 to break bubbles in the liquid layer and enhance the defoaming function.

[0048] One end of the feed pipe 30, away from the rotary spray head 31, is sealed to the outlet of the peristaltic pump 33. The other end of the feed pipe 30 passes through the mixing tank 1 and extends to the bottom center of the mixing tank 1, where it is connected to the rotary spray head 31. A rotary bearing 32 is fixedly installed at the bottom of the rotary spray head 31. The rotary spray head 31 is located at the center of the bottom of the mixing tank 1, and its surface has multiple small holes. The material conveyed by the peristaltic pump 33 is pressed into the rotary spray head 31 through the feed pipe 30 and then sprayed and diffused outwards at a specific speed and angle through the small holes. The ejected material is directly guided into the lower layer of high-torque, low-speed stirring blades. When the material enters from the center of the tank bottom, it can be immediately captured by the high-speed rotating lower stirring blades and lifted upwards for circulation, avoiding the large amount of air entrained by the "waterfall effect" when feeding from the top, thus reducing foam generation at the source.

[0049] The bottom outlet of the mixing tank 1 is connected to the top of the reducing pipe 20 via a pneumatic valve 19. This pneumatic valve 19 controls the opening and closing of the bottom outlet of the mixing tank 1, thereby isolating and switching between the mixing and settling processes. The bottom end of the reducing pipe 20 is connected to the top end of the spiral guide cylinder 21; the variable diameter structure of the reducing pipe 20 helps to smoothly transition the material flow rate. The bottom end of the spiral guide cylinder 21 is fixedly installed on the top of the settling tank 23, used to smoothly guide the mixed material into the settling tank 23. Multiple guide plates 22 are evenly distributed circumferentially within the inner cavity of the spiral guide cylinder 21, each extending along the axial centerline of the spiral guide cylinder 21. These guide plates 22 guide the material downwards along a spiral trajectory, effectively reducing material impact, promoting bubble escape, and avoiding disturbance to the settled material in the settling tank 23.

[0050] A low-frequency motor 24 is fixedly installed on one side of the inner cavity of the settling box 23. This low-frequency motor 24 provides stable low-speed rotational power for the settling process. The output shaft of the low-frequency motor 24 is coaxially fixedly connected to one end of the second rotating shaft 26 via a coupling to ensure efficient power transmission. The second rotating shaft 26 has helical blades 27 evenly distributed around its circumference. The edges of the helical blades 27 maintain a constant gap with the inner wall of the settling box 23. During low-speed rotation, the helical blades 27 can push the ink in the settling process, promoting the upward escape of internal air bubbles, while avoiding disturbing the settled pigments and ensuring the settling effect. The second rotating shaft 26 is supported by two sets of ball bearings 25 arranged at intervals along its axial direction. One set of ball bearings 25 is located near the motor end, and the other set is located far from the motor end. The outer rings of the two sets of ball bearings 25 are respectively interference-fitted with the corresponding mounting holes on both sides of the settling box 23, forming a reliable double-point support structure to ensure smooth and reliable shaft operation. The settling tank 23 is equipped with support frames 28 evenly distributed around its bottom outer perimeter to stably support the entire structure of the settling tank 23. The axis of the discharge pipe 29 is spatially opposite to the axis of the second rotating shaft 26. This arrangement can avoid the generation of eddies during discharge, ensure the smooth discharge of settled material, and prevent the bottom sediment from rising again.

[0051] The mixing tank 1 and the settling tank 23 are covered by an outer shell 34, which provides overall protection for the equipment and isolates operating noise. A display screen 35 is obliquely mounted on the front of the outer shell 34. This display screen 35 displays real-time operating parameters such as mixing speed, settling time, and temperature information, facilitating operator monitoring of the production process. Below the display screen 35, several control buttons 36 are arranged horizontally. Each control button 36 corresponds to one of the equipment's mixing, heating, settling, and cleaning function modules, enabling centralized control of the equipment operation. An alarm light 37 is vertically fixedly installed at one corner of the top of the outer shell 34. This alarm light 37 is linked to various sensors inside the equipment. When abnormal temperature, motor overload, or excessive liquid level occurs, it can emit an audible and visual alarm, promptly alerting the operator to intervene. A cabinet door 38 is hinged to the side of the outer shell 34 near the discharge pipe 29, and a handle 39 is fixedly installed in the center of the outer surface of the cabinet door 38. By opening the cabinet door 38, the internal components such as the mixing tank 1 and the settling tank 23 can be easily inspected and maintained, greatly improving the maintainability and ease of operation of the equipment.

[0052] Example 2:

[0053] Please see Figure 6 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with the following slight differences:

[0054] A helical static mixer 40 is coaxially fixedly installed inside the cavity of the feed pipe 30. This static mixer 40 enables low-shear, continuous pre-mixing of materials during transport, effectively improving the efficiency of subsequent main mixing processes. The static mixer 40 is equipped with guide vanes 44 extending continuously along the axial direction of the feed pipe 30. Their unique helical structure can divide and recombine the material flow, ensuring thorough preliminary mixing of different components before they enter the mixing tank 1. The edges of the guide vanes 44 are fixedly connected to the inner wall of the feed pipe 30, ensuring structural stability and sealing, preventing material leakage or short circuits. The helix angle of the guide vanes 44 is optimized based on the diameter of the feed pipe 30 to balance flow resistance and mixing effect, ensuring smooth material transport at a suitable flow rate and turbulent state, avoiding blockages and optimizing dispersion.

[0055] Example 3:

[0056] Please see Figures 7 to 8 and Figure 12 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with the following slight differences:

[0057] The settling chamber 23 has multiple ultrasonic vibrating plates 43 evenly distributed circumferentially on its inner sidewalls. These ultrasonic vibrating plates 43 are fixedly connected to the inner wall of the settling chamber 23. During operation, the ultrasonic vibrating plates 43 generate high-frequency mechanical vibrations, effectively breaking down micro-bubbles remaining in the ink during the settling process, accelerating their aggregation and floating, and preventing pigment particles from settling and forming scale on the chamber wall, significantly improving the clarity and uniformity of the final product. The top surface of the settling chamber 23 has a mounting hole 45. One end of an air outlet pipe 42 is sealed to this mounting hole 45, and the other end has an air outlet port 46. A reed-type one-way suction valve 41 is embedded in the air outlet port 46. This reed-type one-way suction valve 41 only allows gas inside the settling chamber 23 to escape while preventing external air from entering, thereby maintaining a stable micro-negative pressure environment inside the chamber during the defoaming process, further promoting bubble escape and preventing secondary oxidation. The reed-type one-way suction valve 41 is fixed to the top outer wall of the settling box 23 by bolt assembly. This installation method facilitates the disassembly, replacement, and maintenance of the reed-type one-way suction valve 41. Support frames 28 are evenly distributed and fixed along the outer periphery of the bottom of the settling box 23, providing stable support for the entire settling unit and ensuring the stability and safety of the equipment during operation. At the same time, raising the bottom of the box provides sufficient operating space for the installation and maintenance of the discharge pipe 29.
