Description

Technical Field

[0001] This utility model relates to the field of paint processing technology, specifically to a stirring and color-matching device for paint production. Background Technology

[0002] Paint is a chemical mixture that adheres firmly to the surface of an object, serving protective, decorative, marking, and other special purposes. A paint is a material that can be applied to the surface of an object using different application techniques to form a firmly adhering, continuous solid film with a certain strength. This film is commonly called a coating film, also known as a paint film or coating layer. Paint generally consists of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. The composition may vary slightly depending on performance requirements; for example, varnishes may not contain pigments and fillers, and powder coatings may not contain solvents. It belongs to organic chemical polymer materials, and the resulting coating film is a type of polymer compound. According to the modern classification of chemical products, paint belongs to fine chemical products. Modern paints are gradually becoming a multifunctional engineering material and an important sector within the chemical industry.

[0003] In the paint production process, various paint raw materials need to be diluted, tinted, and stirred to ensure the uniformity of the paint color. Existing new paint production dilution and tinting mixing kettles require frequent opening and observation during the paint production process. Because the paint is quite thick inside the mixing kettle, it is difficult to observe, and tools are needed to lift it up for inspection, making it inconvenient to use. Summary of the Invention

[0021] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims. Example

[0022] refer to Figures 1-3 This embodiment proposes a stirring and color-matching device for paint production, used for stirring and color-matching coatings. The stirring and color-matching device for paint production may include: The mixing tank 1 can be a cylindrical structure. The interior of the mixing tank 1 forms a mixing cavity, allowing paint raw materials to enter and mix inside, forming a uniform paint liquid. The mixing tank 1 may include a lid 2 and a body 3. The body 3 can be a cylindrical structure with a conical bottom. The lid 2 is a disc structure, fixedly covering the top of the body 3. The lid 2 can be placed on the ground or magnetically attached, making it easy to open and clean the mixing tank 1. Alternatively, the lid 2 and body 3 can be connected by threads, snap-fit, or other methods, which will not be elaborated here. The bottom of the mixing tank 1 is fixedly placed on a support frame 5. The support frame 5 supports the mixing tank 1, increasing its support area and operating height, thus ensuring stable placement and ease of operation. The support frame 5 may include a circular placement ring and support legs. The circular placement ring may be an L-shaped circular ring structure with an inner radius the same as the outer diameter of the bottom of the mixing tank 1, allowing the mixing tank 1 to be placed inside the circular placement ring. The support legs are fixedly connected to the bottom of the circular placement ring. Three support legs may be provided, bent outwards; details are not elaborated here. The mixing tank 1 can be fixedly connected to the support frame 5 with bolts, ensuring stable placement. A discharge pipe 6 may be connected to the bottom of the mixing tank 1, allowing the mixed paint liquid inside the mixing tank 1 to be discharged through the discharge pipe 6. Due to the high viscosity of the paint liquid, the discharge pipe 6 is connected to the middle of the bottom of the mixing tank 1, facilitating the discharge of the paint liquid from the mixing tank 1; details are not elaborated here. A feed hopper 4 may be fixedly connected to the top of the mixing tank 1, allowing for convenient addition of paint raw materials. The feed hopper 4 may be fixedly connected to the top of the tank lid 2, or possibly connected to the tank body 3; details are not elaborated here.

[0023] A rotating shaft 12 is rotatably positioned on the internal axis of the mixing tank 1. A stirring plate 13 is fixedly connected to the rotating shaft 12. The stirring plate 13 can be a spiral plate structure with its inner side inclined in the direction of rotation. The stirring plate 13 can rotate with the rotating shaft 12, thereby pushing the liquid inside the mixing tank 1 to flow outward, downward, or upward, thus accelerating the mixing of the paint liquid. The number of stirring plates 13 can be 2-4, with three being preferable; specific details will not be elaborated here.

[0024] A rotation drive component 7 is mounted on the mixing tank 1 and is connected to the portion of the rotating shaft 12 that extends out of the mixing tank 1. The rotation drive component 7 drives the rotating shaft 12 to rotate. The rotating shaft 12 is rotatably and sealed to the mixing tank 1, which is existing technology and will not be described in detail here. The rotation drive component 7 can be a combination of a motor and a pulley, which will not be described in detail here. The feed hopper 4 is fixedly connected to the top center of the mixing tank 1. The top of the rotating shaft 12 can extend into the interior of the feed hopper 4. A feed spiral blade 11 is fixedly connected to the top of the rotating shaft 12. The feed spiral blade 11 can rotate with the rotating shaft 12 to transport the viscous liquid or solid inside the feed hopper 4 into the interior of the mixing tank 1, thereby facilitating feeding. The bottom of the rotating shaft 12 is a hollow tubular structure, with a discharge port 15 at the bottom. The discharge port 15 is connected to the top of the hollow tubular structure, and the discharge pipe 6 is connected to the bottom of the hollow tubular structure via a rotating connector. A discharge spiral blade 14 is fixedly connected to the lower part of the rotating shaft 12. The discharge spiral blade 14 is located inside the mixing tank 1, with its edge contacting the bottom inner wall of the mixing tank 1. The discharge spiral blade 14 can rotate with the rotating shaft 12, cleaning the paint liquid inside the mixing tank 1 and conveying it to the discharge port 15, where it enters the hollow tubular structure and is finally discharged from the discharge pipe 6. This facilitates the cleaning of the paint liquid inside the mixing tank 1, ensuring more thorough discharge. An observation window can also be provided on the mixing tank 1 to observe the condition of the paint liquid inside.

[0025] An observation tube 8, which can be installed on the mixing tank 1, is an arc-shaped, transparent tube with a radius typically between 10-20 mm. Both ends of the observation tube 8 are connected to the mixing tank 1. The plane of the observation tube 8 can be perpendicular to the direction of the corresponding rotating shaft 12, allowing the paint liquid inside the mixing tank 1 to enter the observation tube 8 under the push of the rotating shaft 12. This facilitates observation of the paint color and timely adjustment. Direct observation through the observation window makes it difficult to determine the depth of the paint liquid due to its thickness, leading to data distortion. Observation through the observation tube 8 allows for quantitative thickness measurement of the paint liquid, precise determination of various colors, accurate observation, and convenient color matching. A detection camera 9 can also be fixedly installed on the mixing tank 1. The detection camera 9 can take pictures of the inside of the observation tube 8 to obtain images of the paint liquid inside. When using the detection camera 9, an isolation cover, a supplementary light, and a background plate need to be installed. The background plate is placed behind the observation tube 8 to facilitate the separation of the observation tube 8 from the background color. The background plate is generally green or white, and the specific color will not be elaborated here. The isolation cover is fixedly installed on the outer wall of the mixing tank 1 and covers the observation tube 8 inside. The isolation cover can prevent external light from interfering with the shooting. A supplementary light can also be installed inside the isolation cover to provide supplementary lighting for the observation tube 8. The specific technology is prior art and will not be elaborated here. The rotation drive 7 and the detection camera 9 can be electrically connected to the controller 10. The controller 10 can control the switching and rotation speed of the rotation drive 7, and can also process and analyze the images. During processing, raw materials are added through the feed hopper 4. The rotating drive 7 is activated, and the rotating shaft 12 rotates under the action of the rotating drive 7, mixing the raw materials inside the mixing tank 1. The paint liquid in the mixing tank 1 is pushed into the observation tube 8 by the rotating shaft 12 and then discharged, thus forming a dynamic equilibrium. After uniform mixing, the detection camera 9 is controlled to take pictures of the observation tube 8 to obtain images of the observation tube 8. The controller 10 obtains the images and analyzes them to obtain the RGB values ​​F of the three primary colors in the images. i i can be 1, 2, or 3; that is, F1, F2, and F3. The method for obtaining the RGB values ​​is existing technology, and details will not be elaborated here. Then we can obtain the color deviation value S=F i +fF i ', where F i 'i' represents the RGB value of the target color for the base color with the number i, and 'f' represents the deviation value, which is generally -20 to -20, although other values ​​are possible, but will not be elaborated here. For example, if we need to mix a green paint liquid with a target RGB value of (0, 225, 0), and the detected RGB value of the transparent circle 3 in the image is (0, 200, 0), then the deviation value is 10. We can then gradually add green toner based on experience, but the specific process will not be detailed here. Example

[0026] refer to Figure 4 The observation tube 8 may include a transparent tube body 17 and mounting pieces 16. The transparent tube body 17 is a transparent arc-shaped tube, which can be a glass tube or an acrylic tube. Two mounting pieces 16 are provided and fixedly connected to both ends of the transparent tube body 17. Two through holes can be pre-drilled on the side wall of the mixing tank 1. When installing the transparent tube body 17, the holes at both ends of the transparent tube body 17 are aligned with the through holes, and the mounting pieces 16 are fixed to the outer wall of the mixing tank 1. The mounting pieces 16 may have mounting holes, and the mounting pieces 16 are fixed to the mixing tank 1 by screws passing through the mounting holes. Of course, they can also be fixed by adhesive, but the details are not elaborated here. The transparent tube body 17 may be connected to a liquid inlet pipe 18, and the liquid inlet pipe 18 is provided with a control valve 19. Opening the control valve 19 allows the cleaning liquid to be introduced into the transparent tube body 17 to clean the transparent tube body 17. Closing the control valve 19 prevents the paint liquid in the transparent tube body 17 from flowing out.

For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this disclosure can be achieved, and this is not limited herein.
