A kind of paint toning method and paint online toning system using the method

Abstract

The invention relates to a paint color matching method. The paint color matching method comprises the following steps: firstly, putting a material carrying barrel on a conveying line; secondly, conveying the material carrying barrel below a weight metered color paste distributor, and filling the color paste according to 95 to 98 percent of the preset total weight ratio of the color paste by using the weight metered color paste distributor; thirdly, conveying the material carrying barrel below a volume metered color paste distributor, and filling the color paste according to 2 to 5 percent of the preset total weight ratio of the color paste by using the volume metered color paste distributor; fourthly, filling the paint into the material carrying barrel below a weight metered basic paint distributor; and fifthly, performing a cover sealing process on the material carrying barrel, and performing a uniformly mixing process in the material carrying barrel. The invention also discloses an on-line paint color matching system. The paint color matching method and the on-line paint color matching system have the beneficial effects that 1, the advantages of quick filling, precise filling and the like are realized by utilizing the weight metered color paste distributor and the volume metered color paste distributor, and the color paste color difference proportional error is extremely small; 2, sewage is not discharged during the filling process, and the environment-friendly production requirements are met.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a paint coloring method and an online paint coloring system applying the method. Background technique [0002] The manufacture of color paint (or color paint) is usually prepared by adding different proportions of color paste (or colorant) to white paint or varnish. The market demand for colored paints is increasing. Whether it is architectural coatings, industrial coatings, furniture coatings, floor coatings, anti-corrosion coatings, or plastic coatings and other coatings for different purposes in the coatings industry, end users have constant requirements for the decoration of coatings. Improvement makes the manufacturing efficiency and color accuracy of paints particularly important in the color mixing process. [0003] Taking architectural paint, which has the largest production and sales volume in the paint industry, as an example, architectural paint coloring is ...

Problems solved by technology

The measurement methods of color paste filling are mainly divided into gravimetric measurement and volumetric measurement. After the color paste is filled, the gravimetric measurement method needs the weighing module to continuously feed back the actual measurement value to the control system. The work efficiency is very low under high conditions, especially at the end, it usually takes about 6 minutes to inject all the components of a barrel of 20 kg; the volumetric metering speed is faster, and it usually takes more than 6 minutes to inject all the components of a barrel of 20 kg. The time is about 2 minutes, but due to the wear and tear of the pump body after long-term operation, the measurement error of the color paste will continue to increase, and the requirements for the color paste are relatively high, such as the color paste must not have air bubbles, and the color paste must not have sedimentation etc. Generally, volumetric metering equipment that runs frequently will cause inaccurate metering due to the pump body after running for a period of time, resulting in obvious color difference in the final paint product

[0006] For example, the State Intellectual Property Office has disclosed a name: a color mixing machine system, the application number is 200580034959.6, which is mainly aimed at the color mixing machine that injects volumetrically, because the feeding pump needs to be used regularly after long-term wear and tear. The scale is calibrated to prevent excessive errors from affecting the accuracy of the final color adjustment, but the larger the capacity of the container, the greater the error
