Description

Technical Field

[0001] This application relates to the field of automotive coating preparation equipment technology, and in particular to a preparation equipment for a high-strength, wear-resistant waterborne acrylic polyurethane automotive coating. Background Technology

[0002] The performance of automotive coatings has a crucial impact on the appearance quality, service life, and environmental characteristics of automobiles. High-strength, abrasion-resistant waterborne acrylic polyurethane automotive coatings, with their excellent abrasion resistance, high strength, and environmentally friendly properties, are increasingly widely used in the automotive coating industry. The quality of this coating's preparation is closely related to the performance of the preparation equipment. The equipment needs to precisely mix and disperse various raw materials to ensure the uniform distribution of the coating components, thereby imparting excellent performance to the coating.

[0003] An existing patent (publication number: CN211963996U) discloses equipment for preparing high-strength, wear-resistant waterborne acrylic polyurethane automotive coatings. A mixing tank is connected to a base plate, and a rotating column is installed inside the mixing tank. Stirring arms are fixedly connected around the rotating column, and both ends of the rotating column are movably connected to bearings fixedly connected to the upper and lower ends of the mixing tank. In this design, mixing tanks one and two use a single shaft and a dual shaft to drive the stirring blades to mix different coatings.

[0004] However, the stirring blades of the aforementioned equipment are generally designed with a fixed angle. The angle between the blades and the stirring shaft is fixed during production and cannot be dynamically adjusted according to the viscosity, ratio, and other characteristics of the coating. When the viscosity of the coating is different or the ratio changes, the fixed-angle stirring blades cannot be adjusted according to the actual situation, resulting in low stirring efficiency and difficulty in fully mixing the components of the coating, thus affecting the quality of the coating. Utility Model Content

[0005] The purpose of this application is to provide a preparation device for high-strength, wear-resistant waterborne acrylic polyurethane automotive coatings. This device has the advantages of being able to flexibly adjust the angle of the stirring blades according to the viscosity, ratio, and other characteristics of the coating, effectively improving the stirring efficiency, ensuring that all components of the coating are fully and uniformly mixed, and ensuring that coatings with different properties can be fully and uniformly mixed. This solves the problems mentioned in the background art.

[0006] The equipment for preparing high-strength, wear-resistant waterborne acrylic polyurethane automotive coating provided in this application adopts the following technical solution: It includes a mixing tank, a tank cover installed on the upper side of the mixing tank, a main rotating shaft rotatably connected to the inner side of the tank cover, a drive motor fixedly embedded on the upper side of the tank cover, and the output end of the drive motor fixedly connected to one end of the main rotating shaft. Multiple equidistantly arranged angle adjustment components are arranged on the outer side of the main rotating shaft. Each angle adjustment component has five circumferentially arrayed stirring blades on its outer side. Each angle adjustment component includes a component box fixedly connected to the outer side of the main rotating shaft. A turntable is arranged on the inner side of the component box, and a conical toothed ring is fixedly connected to the bottom surface of the turntable. Five circumferentially arrayed connecting shafts are rotatably connected to the inner side of the component box, and one end of each connecting shaft is fixedly connected to the outer side of the stirring blades. A conical gear is fixedly connected to the other end of each connecting shaft, and the conical gear meshes with the conical toothed ring. A feed pipe is installed on the inner side of the tank cover.

[0007] By adopting the above technical solution, a drive motor is set to drive the main shaft to rotate, thereby driving the angle adjustment component and the stirring blades to mix and stir the coating in the mixing tank. When it is necessary to adjust the angle of the stirring blades, the rotating disc uses the meshing of the conical toothed ring and the conical gear to drive the connecting shaft to rotate, thereby realizing the adjustment of the stirring blade angle. Thus, the stirring blade angle can be flexibly adjusted according to the viscosity, ratio and other characteristics of the coating, effectively improving the stirring efficiency, ensuring that all components of the coating are fully and evenly mixed, and ensuring that coatings with different properties can be fully and evenly mixed, thereby guaranteeing the final coating product and improving the coating quality.

[0008] Preferably, a connecting frame is fixedly connected to the outer side of the main rotating shaft, and five auxiliary rotating shafts in a circular array are rotatably connected to the inner side of the connecting frame.

[0009] By adopting the above technical solution, the cooperation between the connecting frame and the secondary rotating shaft allows the secondary rotating shaft to rotate together with the main rotating shaft, enabling the coating to be stirred from multiple directions, further enhancing the stirring effect, making the components of the coating more fully mixed, and further improving the uniformity and efficiency of mixing.

[0010] Preferably, a gear ring is fixedly connected to the inner side of the box cover, and a transmission gear is fixedly connected to one end of each of the five auxiliary rotating shafts, wherein the transmission gear meshes with the gear ring.

[0011] By adopting the above technical solution, the gear ring meshes with the transmission gear, so that the secondary shaft can rotate independently while rotating with the main shaft, realizing the compound motion of the secondary shaft, expanding the stirring range, and improving the comprehensiveness and uniformity of stirring.

[0012] Preferably, each of the secondary rotating shafts is fixedly connected to a plurality of equally spaced fixing sleeves on its outer side, and each of the fixing sleeves is fixedly connected to a stirring rod in a circumferential array on its outer side.

[0013] By adopting the above technical solution, the fixed sleeve and stirring rod on the outside of the auxiliary rotating shaft, when the auxiliary rotating shaft rotates with the main rotating shaft and also rotates on its own, enable the stirring rod to stir the coating from more positions and directions, thereby enhancing the stirring effect, making the coating mix more evenly, and improving the stirring efficiency.

[0014] Preferably, a discharge pipe is fixedly connected to the inner side of the mixing tank, and a valve is fixedly installed on the outer side of the discharge pipe.

[0015] By adopting the above technical solution, the above discharge pipe and valve facilitate the discharge of the coating after mixing. By controlling the valve, the discharge rhythm can be flexibly controlled, avoiding coating residue and improving the convenience and practicality of the equipment.

[0016] Preferably, an annular groove is provided on the inner side of the component box, and the outer side of the turntable is slidably connected to the inner side of the annular groove.

[0017] By adopting the above technical solution, the outer side of the turntable is slidably connected to the annular groove, which stabilizes the rotation of the turntable and ensures smooth rotation when adjusting the angle of the stirring blades, thus guaranteeing the reliability and stability of the angle adjustment structure.

[0018] Preferably, a worm gear is fixedly connected to the upper side of the turntable, an external box is fixedly connected to the inner side of the component box, and a worm is rotatably connected to the inner side of the external box, with the worm meshing with the worm gear.

[0019] By adopting the above technical solution and utilizing the meshing action of the worm gear and worm, a high-precision transmission structure is formed, which can achieve precise control of the rotation of the turntable, thereby accurately adjusting the angle of the stirring blades, making operation more convenient and improving the controllability of angle adjustment.

[0020] Preferably, a hexagonal block is rotatably connected to the inner side of the external box, and the rotating end of the hexagonal block is fixedly connected to the rotating shaft end of the worm gear.

[0021] By adopting the above technical solution, the hexagonal block is fixedly connected to the end of the worm shaft, which makes it easy for workers to quickly rotate and adjust it using tools such as wrenches. When needed, the hexagonal block can be manually rotated to adjust the worm, thereby realizing the manual adjustment of the angle of the stirring blade, increasing the flexibility of angle adjustment and adapting to different adjustment needs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This equipment for preparing high-strength, wear-resistant waterborne acrylic polyurethane automotive coatings utilizes an angle adjustment assembly with a worm gear and worm shaft meshing, coupled with a conical gear ring and conical gear transmission, to flexibly adjust the angle of the stirring blades. This allows for flexible adjustment of the stirring blade angle based on the coating's viscosity, mixing ratio, and other characteristics, effectively improving stirring efficiency and ensuring that coatings with different properties are fully and uniformly mixed. Simultaneously, the connection frame, secondary rotating shaft, gear ring, and transmission gear work together to allow the secondary rotating shaft to rotate while following the main rotating shaft, achieving a composite motion. Combined with a fixed sleeve and stirring rod, the coating can be stirred from multiple directions and over a wide range, improving stirring efficiency, ensuring thorough and uniform mixing of all coating components, and guaranteeing the quality of the coating product.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: Equipment for preparing a high-strength, wear-resistant waterborne acrylic polyurethane automotive coating. Please refer to... Figure 1 , Figure 2 and Figure 4The system includes a mixing tank 1, a tank cover 2 mounted on the upper side of the mixing tank 1, a main rotating shaft 3 rotatably connected to the inner side of the tank cover 2, a drive motor 4 fixedly embedded in the upper side of the tank cover 2, and the output end of the drive motor 4 fixedly connected to one end of the main rotating shaft 3. Multiple angle adjustment components 5 are arranged at equal intervals on the outer side of the main rotating shaft 3. Each angle adjustment component 5 has five circumferentially arrayed stirring blades 6 on its outer side. The angle adjustment component 5 includes a component box 501 fixedly connected to the outer side of the main rotating shaft 3. A turntable 502 is arranged inside the component box 501, and a conical toothed ring 503 is fixedly connected to the bottom surface of the turntable 502. A connecting shaft 504 is rotatably connected to five circular arrays, and one end of the connecting shaft 504 is fixedly connected to the outside of the stirring blade 6. The other end of each connecting shaft 504 is fixedly connected to a bevel gear 505. The bevel gear 505 and the bevel gear ring 503 mesh with each other. When the turntable 502 rotates, the connecting shaft 504 is driven to rotate through the meshing of the bevel gear ring 503 and the bevel gear 505, thereby realizing the adjustment of the angle of the stirring blade 6. Thus, the angle of the stirring blade 6 can be flexibly adjusted according to the viscosity, ratio and other characteristics of the coating, effectively improving the stirring efficiency and ensuring that the components of the coating are fully and evenly mixed. A feed pipe 7 is installed on the inner side of the box cover 2.

[0027] Please refer to Figure 4 and Figure 5 An annular groove 506 is provided on the inner side of the component box 501. The outer side of the turntable 502 is slidably connected to the inner side of the annular groove 506. The annular groove 506 stabilizes the rotation of the turntable 502, ensuring smooth rotation when adjusting the angle of the stirring blades 6, and guaranteeing the reliability and stability of the angle adjustment structure. A worm gear 507 is fixedly connected to the upper side of the turntable 502. An outer box 508 is fixedly connected to the inner side of the component box 501. A worm 509 is rotatably connected to the inner side of the outer box 508. The worm 509 and the worm gear 507 mesh with each other. The meshing action of the worm gear 507 and the worm 509... A high-precision transmission structure is formed, enabling precise control of the rotation of the turntable 502, thereby accurately adjusting the angle of the stirring blade 6. This makes operation more convenient and improves the controllability of angle adjustment. A hexagonal block 510 is rotatably connected to the inner side of the outer housing 508, and the rotating end of the hexagonal block 510 is fixedly connected to the shaft end of the worm gear 509. This fixed connection between the hexagonal block 510 and the shaft end of the worm gear 509 allows operators to quickly adjust its rotation using tools such as wrenches. When needed, the hexagonal block 510 can be manually rotated to adjust the worm gear 509, thus achieving manual adjustment of the angle of the stirring blade 6. This increases the flexibility of angle adjustment and can adapt to different adjustment needs. Example 2: A preparation apparatus for a high-strength, wear-resistant waterborne acrylic polyurethane automotive coating. Please refer to [reference needed]. Figure 1 , Figure 2 and Figure 3A connecting frame 8 is fixedly connected to the outer side of the main rotating shaft 3. Five auxiliary rotating shafts 9 arranged in a circular array are rotatably connected to the inner side of the connecting frame 8. The cooperation between the connecting frame 8 and the auxiliary rotating shafts 9 allows the auxiliary rotating shafts 9 to rotate together with the main rotating shaft 3, enabling stirring of the coating from multiple directions. This further enhances the stirring effect, ensuring more thorough mixing of the coating components and improving the uniformity and efficiency of the mixing. A gear ring 11 is fixedly connected to the inner side of the cover 2. A transmission gear 10 is fixedly connected to one end of each of the five auxiliary rotating shafts 9. The transmission gear 10 meshes with the gear ring 11. This meshing allows the auxiliary rotating shafts 9 to rotate independently while rotating with the main rotating shaft 3, achieving a compound motion of the auxiliary rotating shafts 9, expanding the stirring range, and improving the stirring efficiency. To ensure comprehensiveness and uniformity, multiple equidistant fixed sleeves 12 are fixedly connected to the outer side of each secondary rotating shaft 9. Each fixed sleeve 12 is fixedly connected to the outer side of three circumferentially arrayed stirring rods 13. When the secondary rotating shaft 9 rotates along with the main rotating shaft 3, the fixed sleeves 12 and stirring rods 13 on the outer side of the secondary rotating shaft 9, combined with their own rotation, allow the stirring rods 13 to stir the coating from more positions and directions, enhancing the stirring effect, making the coating more uniform, and improving stirring efficiency. A discharge pipe 14 is fixedly connected to the inner side of the mixing box 1, and a valve 15 is fixedly installed on the outer side of the discharge pipe 14. The discharge pipe 14 and valve 15 facilitate the discharge of the coating after stirring. By controlling the valve 15, the discharge rhythm can be flexibly controlled, avoiding coating residue and improving the convenience and practicality of the equipment.

[0028] The implementation principle of this application embodiment is as follows: When the equipment is working, firstly, the angle of the stirring blade 6 is adjusted according to the characteristics of the coating. At this time, the operator rotates the hexagonal block 510 through an external tool, which drives the worm gear 509 to rotate. The worm gear 509 meshes with the worm wheel 507, which drives the turntable 502 to rotate. At this time, the rotation of the turntable 502 drives the bottom conical gear ring 503 to rotate. Under its meshing with the conical gear 505, it drives the connecting shaft 504 to rotate, thereby realizing the adjustment of the angle of the stirring blade 6. After the adjustment is completed, the coating to be mixed is injected into the interior of the mixing tank 1 through the feed pipe 7. Then, the drive motor 4 is started, and its output end drives the main rotating shaft 3 to rotate. The outer angle adjustment component 5, stirring blade 6, and connecting frame 8 rotate together with the main shaft 3. At this time, the rotation of the connecting frame 8 can drive the inner auxiliary shaft 9 to perform circular motion. At this time, the transmission gear 10 at one end of the auxiliary shaft 9 meshes with the gear ring 11 on the inner side of the box cover 2, so that the auxiliary shaft 9 can rotate independently while rotating with the main shaft 3. Then, the fixing sleeve 12 and stirring rod 13 on the outer side of the auxiliary shaft 9, as well as the stirring blade 6 on the outer side of the angle adjustment component 5, stir the coating in the mixing box 1 from multiple directions and positions, thereby further improving the uniformity of mixing and stirring efficiency. After the coating is stirred, the valve 15 on the outer side of the discharge pipe 14 can be opened to discharge the coating.
