Description

Technical Field

[0001] This utility model relates to the field of paint processing technology, specifically to a paint color matching device. 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

By observing the transparent ring axially, the thickness of the paint liquid can be fixed, and various colors of the paint liquid can be accurately obtained. The observation is accurate and it is convenient for color mixing. Attached Figure Description

[0033] 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

[0034] refer to Figure 1This embodiment proposes a paint tinting device for mixing and tinting coatings. The paint tinting device may include:

[0035] The base 1 forms the installation foundation. It can be a horizontally placed rectangular plate structure, or it can be a welded structure of frame and panel. The base 1 can have a certain weight to increase the stability of the equipment operation. The bottom of the base 1 can be equipped with casters to facilitate the movement of the equipment and make it easy to transport.

[0036] The rotating frame 2 can be a rectangular plate structure, rotatably mounted on the base 1. By rotating the rotating frame 2, the base 1 and the rotating frame 2 can form different angles. The rotating frame 2 needs to have a certain rigidity to ensure that it is not easily deformed.

[0037] The hydraulic rod 18 is rotatably mounted on the base 1, and its output end is rotatably connected to the bottom of the rotating frame 2. By extending and retracting the hydraulic rod 18, the rotating frame 2 can be driven to rotate. A mounting groove can be opened on the upper surface of the base 1, and the hydraulic rod 18 is installed inside the mounting groove. When the rotating frame 2 rotates onto the base 1, the base 1 and the rotating frame 2 come into contact, and the hydraulic rod 18 is retracted into the mounting groove.

[0038] A mixing cylinder 4 is rotatably mounted on a rotating frame 2. The mixing cylinder 4 can be a cylindrical structure, or, for easier containment of the paint liquid, a cylindrical structure that is narrower at both ends and wider in the middle. One end has a discharge port 5, and the other end has a feed port 15. Paint raw materials and colorants are added to the mixing cylinder 4 through the feed port 15, and the mixed and tinted paint liquid is discharged through the discharge port 5. The mixing cylinder 4 is installed using a fixing ring. A fixing ring is fixedly mounted on the rotating frame 2, and the mixing cylinder 4 rotates within the fixing ring. Support wheels 14 are rotatably mounted on the upper surface of the rotating frame 2. A track ring 7 is fixedly mounted on the outer wall of the mixing cylinder 4. Two support wheels 14 are clamped and supported on both sides of the lower part of the track ring 7, thus completing the rotational support of the mixing cylinder 4. The track ring 7 can be a groove structure, and the support wheels 14 are rotating column structures that are wider in the middle and narrower at both ends. The two can cooperate and contact each other to prevent axial deflection of the mixing cylinder 4. Of course, there are also two possible combinations of rotating support, which will not be elaborated here. The mixing cylinder 4 can be made of stainless steel, but other materials are not excluded, ensuring that it will not deform during operation.

[0039] A rotating drive structure, connected to the mixing cylinder 4, drives the mixing cylinder 4 to rotate, causing the paint liquid inside to churn and mix. The rotating drive structure may include a motor 12, a gear 13, and a hydraulic rod 18. The motor 12 can be mounted on the rotating frame 2. The output shaft of the motor 12 is coaxially fixedly mounted with the gear 13. A ring of teeth 8 is fixedly provided on the outer wall of the mixing cylinder 4, meshing with the gear 13. Driven by the motor 12, the gear 13 rotates, thereby driving the mixing cylinder 4 to rotate via the teeth 8. Alternatively, the motor 12 can also be coaxially connected to one of the support wheels 14 for a fixed connection, thus completing the drive; details are not elaborated here. A rotating track 6 is fixedly provided on the base 1. Two rotating tracks 6 can be provided, arranged opposite each other. An arc groove is formed on the side of the rotating track 6 facing the mixing cylinder 4. A sliding block is fixedly provided at a corresponding position on the rotating frame 2, slidingly fitting into the arc groove, thereby stabilizing the rotation of the rotating frame 2. An arc-shaped guide rail can be fixedly installed inside the arc groove, and a sliding block is slidably sleeved on the guide rail, thereby making its sliding more stable. A support frame 10 is fixedly installed on the base 1, and a feed hopper 9 is rotatably installed on the support frame 10. The lower part of the feed hopper 9 can be inserted into the interior of the mixing cylinder 4 through the feed port 15. Paint raw materials and colorants can be added into the interior of the mixing cylinder 4 through the feed hopper 9. The feeding hopper 9 may include a hopper body and a feeding pipe, which are connected. The included angle between the hopper body and the feeding pipe is less than a flat angle. When the feeding hopper 9 is in the feeding state, the center of gravity of the feeding hopper 9 is located on the side of its rotation point closer to the mixing cylinder 4. When the rotating frame 2 rotates upward, the bottom of the feeding pipe is inside the feeding port 15 of the mixing cylinder 4. When the rotating frame 2 rotates upward, the mixing cylinder 4 rotates with the rotating frame 2, and the lower edge of the feeding port 15 pushes the feeding pipe to rotate, thereby causing the feeding hopper 9 to rotate on the support frame 10. At this time, the center of gravity of the feeding hopper 9 is located on the side of its rotation point away from the mixing cylinder 4. At this time, the end of the feeding pipe away from the hopper body is always inside the feeding port 15. When the rotating frame 2 rotates to the limit position, the feeding port 15 is inclined upward. This design can provide cleaning space for the feeding port 15, thereby making the inside of the rotating frame 2 easy to clean, avoiding interference with the feeding hopper 9, and making it easy to clean. Of course, the distance from the end of the feed pipe furthest from the hopper to the rotation center of the rotating frame 2 can be greater than the distance from the lower edge of the feed inlet 15 to the rotation center of the rotating frame 2, but less than the distance from the upper edge of the feed inlet 15 to the rotation center of the rotating frame 2. In this way, as the rotating frame 2 rotates to its limit position, the end of the feed pipe furthest from the hopper extends beyond the range of the feed inlet 15, making cleaning easier. When the rotating frame 2 rotates in the reverse direction, the lower edge of the feed inlet 15 will not touch the end of the feed pipe furthest from the hopper, while the upper edge of the feed inlet 15 will touch the end of the feed pipe furthest from the hopper, causing the feed hopper 9 to rotate in the reverse direction, so that its center of gravity returns to the side of its rotation point closer to the mixing cylinder 4.A transparent observation ring 3 is fixedly installed on the mixing cylinder 4. The transparent observation ring 3 is protruding outward and made of transparent material. The width of the transparent observation ring 3 is generally 10-20 mm. The transparent observation ring 3 is connected to the mixing cylinder 4. When the mixing cylinder 4 rotates, the paint liquid enters into the transparent observation ring 3 and tumbles inside. This facilitates axial observation of the paint liquid color, allowing for timely adjustment of the paint liquid color. If the paint liquid inside the mixing cylinder 4 is observed radially directly, it is difficult to obtain the depth of the paint liquid due to its large thickness, resulting in data distortion. By observing axially through the transparent observation ring 3, the paint liquid thickness can be fixed, and various colors of the paint liquid can be accurately obtained, ensuring accurate observation and facilitating color adjustment. A camera 16 is fixedly mounted on the rotating frame 2. The camera 16 is positioned on one side of the observation transparent ring 3, facing the ring 3 and capable of photographing the paint liquid within it, thereby obtaining an image of the paint liquid. The rotating frame 2 may have a groove 17, through which the observation transparent ring 3 can rotate and pass. The camera 16 is installed inside the groove 17. This avoids interference from external light during photography. A supplementary light can also be installed inside the groove 17 to illuminate the observation transparent ring 3, facilitating photography. This is existing technology and will not be elaborated upon here.

[0040] The rotating drive, hydraulic rod 18, and camera 16 are electrically connected to a controller. The controller can control the switching and rotation speed of the rotating drive, as well as the rotation angle of the rotating frame 2. The controller can also receive, process, and analyze images. During processing, raw materials containing paint liquid are added through the feed hopper 9. The controller starts the rotating drive, causing the mixing cylinder 4 to rotate, and the paint liquid tumbles inside the mixing cylinder 4. After the paint liquid is evenly mixed, the camera 16 takes an image of the paint liquid within the observation transparent ring 3. The controller receives the image and analyzes it to obtain the detected RGB value of the observation transparent ring 3. Then, the detected RGB value is compared with the target RGB value, and adjustments are made based on the RGB difference. The target RGB value can be obtained by adding a standard sample inside the mixing cylinder 4 and analyzing the image. For example, if we need to prepare a yellow paint liquid with a target RGB value of (225,225,20), and the RGB value of the transparent circle 3 observed in the image is (225,225,0), we can adjust it by gradually adding some blue toner. The amount added can be adjusted by the amount of paint liquid inside the mixing cylinder 4, which will not be elaborated here. Example

[0041] A push-pull rod 19 is slidably placed inside the rotating frame 2. The push-pull rod 19 can be T-shaped, with both ends extending out from the sides of the rotating frame 2. An embedded groove 20 is provided at the bottom of the rotating track 6. The output end of the hydraulic rod 18 is rotatably connected to the push-pull rod 19. When the mixing cylinder 4 rotates, both ends of the push-pull rod 19 are embedded in the embedded groove 20, thereby fixing the rotating frame 2 and preventing it from shaking during operation. When the hydraulic rod 18 pushes the push-pull rod 19, the hydraulic rod 18 pushes the push-pull rod 19 to slide inside the rotating frame 2, and both ends slide out of the embedded groove 20. When the end of the push-pull rod 19 has completely slid out of the embedded groove 20, the push-pull rod 19 can no longer slide due to the restriction of the structure of the rotating frame 2. The hydraulic rod 18 continues to push, causing the rotating frame 2 to rotate upward. The mixing cylinder 4 on the rotating frame 2 rotates and discharges material at the same time. A receiving container can be placed below the discharge port 5. After material discharge is completed, the hydraulic rod 18 retracts and pulls the push-pull rod 19. The push-pull rod 19, supported by the outer wall of the rotating track 6, cannot slide relative to the rotating frame 2, thus pulling the rotating frame 2 to rotate in the opposite direction. When the rotating frame 2 rotates to contact the base 1, the end of the push-pull rod 19 slides into the recessed groove 20, thereby fixing the rotating frame 2. This connection method enables the linkage between rotation drive and locking, meeting the requirements of paint discharge operations. The push-pull rod 19 has a slope on its side near the rotating track 6, and the upper surface of the recessed groove 20 also has a slope, converting the pulling force into downward pressure, making the rotating frame 2 more stable. A rolling assembly can be provided on the surface of the push-pull rod 19 facing the rotating track 6. The rolling assembly reduces the friction between the push-pull rod 19 and the rotating track 6, making the rotation of the rotating frame 2 smoother.

[0042] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. 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 disclosed in this disclosure can be achieved, and this is not limited herein.

[0043] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
