AI Technical Summary
Existing water-based paint testing and sampling devices cannot achieve quantitative sampling, resulting in material waste and delayed test results. At the same time, they cannot sample multiple water-based paints simultaneously, increasing testing time and costs.
An extraction mechanism comprising a sampling cylinder, a piston, an electric telescopic rod, and a syringe was designed. The piston displacement is precisely controlled by the electric telescopic rod to achieve quantitative sampling, and the sample is injected into multiple sampling bottles through a delivery mechanism. The automatic switching and injection of multiple samples is achieved by the coordinated action of a lead screw and a motor.
It achieves accurate and consistent sample quantity, improves sampling efficiency and sample consistency, meets testing requirements, and ensures repeatability verification of multiple samples.
