Description

Technical Field

[0001] The present application relates to the field of mixing equipment, and in particular to a latex paint color mixing equipment and a color mixing method. Background Art

[0002] Latex paint is a kind of decoration paint commonly used at present, and it generally has a variety of colors to meet the decoration needs of different groups of people. In order to produce latex paint of different colors, it is necessary to add corresponding dyes into the latex paint to adjust the color of the latex paint.

[0003] In the existing related technology, the color of latex paint is generally adjusted by latex paint color adjustment equipment, which generally includes a color mixing box, a latex paint tank for storing latex paint, a dye bottle for storing dye, and a proportional valve group for injecting the dye in the corresponding dye bottle into the color mixing box.

[0004] Specifically, please refer to the utility model patent with announcement number CN 220214057 U, announcement date 2024.02.23, and the name of which is a latex paint color mixing device. This utility model patent mainly injects the latex paint in the latex paint tank into the color mixing box through a feed pipe, and injects the liquid dye in the storage box (the dye bottle) into the color mixing box through a flow proportional valve (the proportional valve group referred to above), so that the latex paint is stirred and mixed to the desired color in the color mixing box.

[0005] After the latex paint is mixed in the color mixing box, it needs to be color checked. When there is an error between the latex paint color and the standard color, it is necessary to correct the parameters of the proportional valve group of the control system multiple times, and mix the latex paint in the color mixing box multiple times until the parameters of the proportional valve group are adjusted accurately and the error between the latex paint color and the standard color is adjusted to within the allowable range.

[0006] Regarding the above-mentioned related technologies, since the color mixing box contains a lot of latex paint, after the dye is injected into the color mixing box, the dye and the latex paint need to be stirred for a long time to ensure that the dye and the latex paint are fully mixed before the color of the latex paint can be checked again, which makes the color checking of the latex paint more inconvenient. Summary of the invention

[0007] In order to facilitate rapid and accurate adjustment of the parameters of the proportional valve group, thereby facilitating the color calibration of latex paint, the present application provides a latex paint color adjustment device.

[0008] The present application provides a latex paint coloring device and a coloring method using the following technical solutions: A latex paint color mixing device comprises a proportional valve group and a color mixing box, wherein the proportional valve group is used to convey dyes, the color mixing box is provided with a color mixing chamber, the color mixing chamber is used to mix dyes and latex paints, and the latex paint color mixing device further comprises a calibration box; The calibration box is provided with a calibration chamber, a dye inlet and a latex paint inlet, the calibration chamber is used to mix the dye and the latex paint, the volume size of the calibration chamber is smaller than the volume size of the color mixing chamber, the calibration box is equipped with a color sensor, the color sensor is used to identify the color of the latex paint in the calibration chamber, and the color sensor is electrically connected to the proportional valve group; The dye inlet is connected to the calibration chamber and connected to the proportional valve group, the latex paint inlet is connected to the calibration chamber and connected to the color mixing chamber, and an input device is provided between the color mixing chamber and the calibration chamber, and the input device is used to transport the latex paint in the color mixing chamber to the calibration chamber.

[0009] By adopting the above technical solution, after the latex paint is mixed in the color mixing box, the latex paint is transported to the calibration box through the conveying device, and the latex paint in the calibration box is calibrated by the color sensor.

[0010] When there is an error between the latex paint color and the standard color, the parameters of the proportional valve group are promptly corrected according to the calibration results of the color sensor, and a small amount of latex paint is mixed and colored according to the corrected parameters. Therefore, the need to stir the dye and latex paint for many times and for a long time is reduced, and the parameters of the proportional valve group are accurately adjusted in time, which facilitates the color calibration of the latex paint.

[0011] In addition, before the latex paint in the color mixing box is adjusted, a small amount of latex paint is pre-adjusted in the calibration box according to the preset parameters of the proportional valve group. After the latex paint is pre-adjusted, the pre-adjusted results of the latex paint are checked according to the color sensor. According to the calibration results of the color sensor, the parameters of the proportional valve group are promptly corrected, and then the large amount of latex paint in the color mixing box is adjusted. The situation where the dye and latex paint need to be stirred for many times and for a long time is reduced, and the parameters of the proportional valve group are adjusted accurately in time, so as to facilitate the color calibration of the latex paint.

[0015] By adopting the above technical solution, on the one hand, by setting a fixed illumination mode, it is convenient for the color sensor to check the color of the latex paint under fixed illumination conditions, thereby ensuring the accuracy of the latex paint color check. On the other hand, by setting multiple illumination modes, the shell cavity can simulate the illumination conditions in different environments, such as sunny days, cloudy days, rainy days, dusk or night, so as to facilitate the judgment of the color displayed by the latex paint in actual conditions, thereby facilitating the comprehensive and multi-dimensional verification and judgment of the color adjustment results of the latex paint, so that the latex paint can more easily meet the use needs of different users under actual application conditions.

[0019] By adopting the above technical solution, on the one hand, the commutation between the driving worm wheel and the driving worm makes the setting of the driving motor more flexible. On the other hand, the deceleration between the driving worm wheel and the driving worm makes it easier for the driving motor to fully mix the dye with the viscous latex paint.
