How to accurately control the ratio of pigments in an automatic color mixing machine?

The automatic color mixing machine precisely controls the pigment ratio through the following methods:

Hardware section

The pressure sensor and microcontroller form a closed-loop control: the pressure sensor monitors the quality of the pigment in real time and feeds back the data to the microcontroller. The microcontroller controls the opening and closing of the solenoid valve through a power amplification circuit based on a preset formula and ratio, ensuring precise output of the pigment.

High precision batching system: equipped with a high-precision batching system, using pressure sensors and microcontrollers to form a closed-loop control, real-time monitoring of pigment quality and comparison with preset values to ensure accurate and error free pigment addition.

Efficient mixing device: equipped with an efficient mixing system, such as a multi axis mixer or anchor mixer, to ensure that the pigment is evenly distributed in the mixing chamber. Some devices are also designed with special pipes and nozzles to promote rapid and uniform mixing of pigments.

Software section

Intelligent algorithms and preset programs: The automatic color mixing machine is equipped with intelligent algorithms that can automatically select good mixing parameters and programs based on the characteristics and formula requirements of the pigment. For special pigments or complex formulas, the device can call the preset mixing program to ensure consistency in the mixing effect.

Real time monitoring and feedback: The equipment is equipped with a color sensor that can monitor the color changes during the mixing process in real time, and automatically adjust the mixing time and speed based on the monitoring results to ensure that the color achieves the expected uniformity and accuracy.

White balance and environmental correction: In the color recognition process, the automatic color mixer performs white balance operations, extracts correction factors, and eliminates the influence of ambient light on color recognition. This ensures the accuracy of color recognition and blending in different work environments.

Color detection and formula generation: Place the sample in the color gloss detection and analysis system for detection. The system sends the color data to the computer processing system, and the computer generates the color raw material ratio formula based on these data.

Raw material preparation and pressure control: The raw material ratio pressure control device controls the air pressure inside the pigment bottle to be greater than atmospheric pressure, providing power for the transportation of pigments.

Pigment transportation and filling: According to the generated formula, the raw material ratio valve control device controls the conduction time of the corresponding conveying pipeline for each pigment bottle, so that the corresponding pigment is transported through the pipeline to the raw material filling nozzle device under air pressure, and then filled into the product storage container.

Real time weighing and feedback control: During the pigment filling process, the weighing device measures the weight of the product container in real time and feeds back the data to the computer processing system. The computer calculates the actual amount of each color ingredient based on this data and matches it with the formula data to ensure the accuracy of color matching.

Through the collaborative work of the above hardware and software, the automatic color matching machine can accurately and efficiently complete color matching tasks, and is widely used in multiple industries such as coatings, printing, and textiles, improving production efficiency and product quality, and reducing manual errors and labor intensity.
