What is the working principle of an automatic color mixing machine?

The working principle of an automatic color mixing machine mainly involves the collaborative work of software and hardware. The following is a detailed introduction to the working principle:

1、 Software section

• A huge proportioning database: The software part stores rich proportioning data, which has been accumulated through a large number of experiments and practical applications. They provide the foundation for various color adjustments for automatic color grading machines.

• Multiple function integration: The software can not only control the operation of hardware devices, but also store color grading records and related data. This is crucial for subsequent color matching and quality control.

• Color formula generation: Based on the target color input by the user, the software uses complex algorithms and database searches to calculate the required pigment types and their precise proportions to achieve that color.

2、 Hardware part

• Color detection system: The hardware part includes a color gloss detection and analysis system, which is used for color detection and analysis of samples. The system is capable of accurately measuring the color parameters of samples and sending this data to a computer processing system.

• Raw material storage device: The automatic color mixing machine is equipped with multiple color bottles, each of which stores a color raw material. These pigment bottles are connected to the raw material filling nozzle device through a conveying pipeline.

• Raw material ratio control device: including raw material ratio valve control device and raw material ratio pressure control device. The valve control device controls the conduction time of the corresponding conveying pipeline for each pigment bottle based on the formula generated by the computer; The pressure control device controls the air pressure inside the pigment bottle to ensure smooth transportation of the pigment.

• Raw material filling nozzle device: This device is responsible for filling color raw materials from the pigment bottle into the product storage container through the conveying pipeline.

• Product storage and weighing system: including product storage containers and weighing devices. The weighing device can weigh the product container in real time and feedback the weight data to the computer processing system to ensure the accuracy of the pigment addition amount.

• Gas source device: usually an air compressor, providing compressed gas to the pigment bottle to create internal pressure and promote the flow of pigment.

PLC control system: The computer processing system controls the automation operation of the entire color mixing process by setting the parameters of the PLC control system, including the operation of raw material proportioning valves, pressure control devices, and gas source devices.

3、 Workflow

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.

Quality inspection and exception handling: If the actual filling amount matches the formula data and is within the allowable deviation range, the product color matching is successful; If it exceeds the deviation range, it is judged as abnormal color matching, and the system will issue an alarm or automatically make adjustments.

Through the collaborative work of the above software and hardware, 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.
