The upper right side of the tank cover body 2 is provided with a feeding port 201. A feeding sealing cover 202 is installed on the feeding port 201. A drive motor 6 is provided at the center of the upper end of the tank cover body 2. A rotating mounting seat 7 is installed at the lower part of the tank cover body 2. A stirring shaft 8 is installed below the rotating mounting seat 7. The upper end of the stirring shaft 8 is connected to the output shaft of the drive motor 6. A stirring rod 9 is installed at the lower part of the stirring shaft 8. The lower end of the mixing tank 1 is provided with a discharge port 10 and a discharge valve 11 is installed. This invention allows latex paint raw materials to be added to the mixing tank 1 via the feeding port 201. A color paste cup 3 is placed in the cup holder groove 4 and filled with the desired color paste. Color paste is added to the color paste cup 3 via the color paste inlet 302. A weighing sensor 5 measures the weight of the color paste in the color paste cup 3. A color paste electronic control valve 304 controls the amount of color paste flowing out of the color paste outlet 303, ensuring that the color paste in the color paste cup 3 is delivered to the mixing tank 1 in the required precise amount. The process is then initiated. After the drive motor 6 is driven, the power output shaft of the drive motor 6 drives the stirring shaft 8 to rotate at high speed in the mixing tank 1, which drives the stirring rod 9 to stir the color paste and other materials evenly in the mixing tank 1, realizing the color matching of different colors of latex paint, effectively improving the mixing quality of latex paint, and greatly improving the color matching efficiency and effect of latex paint. The discharge valve 11 can realize the discharge of latex paint after stirring, which better and faster ensures the color matching, production and discharge of latex paint, and has the characteristics of safety, labor saving, simplicity and high efficiency.
[0021] Example 2:
[0022] As attached Figure 1-3 As shown, the difference between this embodiment and Embodiment 1 is that there are six weighing sensors 5 on the bottom surface of the cup holder groove 4. The weighing sensors 5 are arranged in a circumferential array with uniform spacing along the center of the cup holder groove 4. The lower end of each weighing sensor 5 is provided with a fixing foot 501, and the fixing foot 501 is fixedly connected to the cup holder groove 4 by a fixing screw 502. By setting multiple weighing sensors 5, the detection data is more accurate and reliable.
[0023] Example 3:
[0024] As attached Figure 1 As shown, the difference between this embodiment and embodiments 1 and 2 is that the upper part of the color paste cup 3 is provided with an exhaust port and an exhaust valve 305 is installed. In actual manufacturing and use, the exhaust valve 305 can timely discharge the air in the color paste cup 3, avoid the generation of air bubbles, and make the color paste addition operation of the color paste electronic control valve 304 more accurate and reliable.
[0025] Example 4:
[0026] As attached Figure 1-2 As shown, the difference between this embodiment and embodiments 1-3 is that there are three cup holder grooves 4 evenly spaced, each with the same diameter and structure, and each containing a color paste cup 3. Handles 301 are symmetrically positioned on both sides of the outer side of each color paste cup 3. In actual use, it is best to place labels or markings on the outside of the color paste cups 3. Different color paste cups 3 hold different colors of color paste, and the two handles 301 allow for easy removal of the color paste cups 3 from the cup holder grooves 4, enabling them to be replaced as needed. Generally, latex paint color pastes are divided into three types: base color paste, intermediate color paste, and adjusting color paste. Base color paste refers to the pigment added to white latex paint, commonly including red, yellow, and blue. Intermediate color paste is a light-colored pigment mixed from the base color pastes, used for mixing dark-colored latex paints. Adjusting color paste is used for fine-tuning colors, commonly including black and white. The three color paste cups 3 allow for easy addition of different colored color pastes such as red, yellow, and blue to the mixing tank 1. They can also be replaced with color paste cups 3 for holding black or white color paste as required, making them even more convenient to use.
[0027] Example 5:
[0028] As attached Figure 1 As shown, the difference between this embodiment and embodiments 1-4 is that the upper end of the mixing tank 1 is provided with a fixed flange 101, and the lower end of the tank cover 2 is provided with an mounting flange 200. The fixed flange 101 and the mounting flange 200 are fixedly connected together by fixing bolts.
[0029] Example 6:
[0030] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1-5 is that the bottom of the inner cavity of the mixing tank 1 is conical, and the discharge port 10 is located at the lower end of the cone; the bottom of the inner cavity of the color paste cup 3 is conical, and the color paste outlet 303 is located at the lower end of the cone. The conical bottom of the inner cavities of the mixing tank 1 and the color paste cup 3 facilitates the complete emptying of the corresponding materials in the inner cavity and also enables effective cleaning of the equipment interior. During cleaning, water is added to the pigment inlet 302, and the pigment electric control valve 304 is opened to allow the cleaning water to flow into the mixing tank 1. Alternatively, the feeding sealing cover 202 can be opened to add cleaning water into the mixing tank 1 through the feeding port 201. At the same time, the drive motor 6 is turned on to rotate the stirring rod 9. Then, the receiving container is placed below the discharge valve 11, and the discharge valve 11 is opened to collect the wastewater from cleaning the pigment cup 3 and the mixing tank 1 into the receiving container. This can achieve thorough cleaning of the inner cavity of the pigment cup 3 and the mixing tank 1, and can avoid the pollution of the working area environment by the cleaning wastewater. This effectively prevents the problem of incomplete cleaning of existing latex paint color matching devices, which affects the quality of the finished latex paint.
[0031] Example 7:
[0032] As attached Figure 1-3 As shown, the difference between this embodiment and embodiments 1-6 is that the discharge valve 11 is an electrically controlled valve, a liquid level sensor 102 is provided on the upper side wall of the inner cavity of the mixing tank 1, and a control device 103 is provided on the outer side of the mixing tank 1. The liquid level sensor 102, drive motor 6, weighing sensor 5, color paste electrically controlled valve 304, and discharge valve 11 are electrically connected to the control device 103 via cables. During operation, firstly, the feeding sealing cover 202 is opened, and the weighed latex paint raw material is added to the mixing tank 1 through the feeding port 201. The liquid level sensor 102 detects whether the actual liquid level in the mixing tank 1 has reached the set position. If it has, the feeding sealing cover 202 is closed. Next, the drive motor 6 is started by the control device 103, driving the stirring shaft 8 and stirring rod 9 to rotate. Then, according to the preset program, the control device 103 uses the weighing sensor 5 to detect whether the color paste in the color paste cup 3 is sufficient. If insufficient, an alarm is triggered. An alarm signal is triggered; subsequently, the color paste control valve 304 opens, and the color paste in the color paste cup 3 flows into the inner cavity of the mixing tank 1 through the color paste control valve 304. At the same time, the weighing sensor 5 detects the weight of the color paste cup 3 and sends a signal. When the set color paste discharge amount is reached, the color paste control valve 304 closes, and the color paste outlet 303 stops conveying color paste into the mixing tank 1. After that, the drive motor 6 drives the stirring rod 9 to continuously stir for a set time to stir the latex paint in the mixing tank 1 evenly. Finally, the discharge valve 11 opens to realize the discharge.
[0033] Furthermore, as needed, an observation window is provided on the middle side wall of the mixing tank 1 to observe the color of the latex paint inside the tank 1. A color sensor is located on the upper part of the control device 103 corresponding to the observation window. A high-definition camera facing outwards and capable of recognizing the color of the color card is located in the middle of the control device 103. The control device 103 contains a processor capable of comparing the color of the color card with the color of the latex paint in the observation window collected by the color sensor. Users can input, search, and select information such as the brand and model of the latex paint raw materials on the control device 103. Based on the brand and model of the latex paint raw materials selected by the user, the software system calculates the color paste color and amount required to produce the corresponding color of the latex paint on the color card. The color paste electronic valve 304 is controlled to add the corresponding color paste. The color sensor detects the color of the latex paint in the observation window and performs calibration processing against the color of the color card recognized by the high-definition camera. This invention enables automatic color calibration and is more convenient to use.
[0034] In addition, as needed, the lower end of the mixing tank 1 is provided with a support leg, and the lower end of the support leg is equipped with a lockable roller. This enables the mixing tank 1 to be moved and locked in place, making it more convenient to use.
