[0002] At present, in the production and construction process of two-component coatings, in order to ensure that the two components (component A and component B) can be fully mixed, a manual or semi-automatic mixing method is usually adopted. This method not only has low efficiency, but also is prone to uneven mixing, resulting in unstable product quality. In addition, the traditional mixing equipment cannot realize continuous feeding, which increases the downtime in the production process and further reduces the overall production efficiency.

The semi-automatic mixing machine: the device drives the stirring paddle by a motor to mechanically stir the two components in the container. Although the degree of automation is high, manual intervention is still required, and continuous feeding cannot be realized, which has the problem of intermittent stop. The full-automatic mixing system: this system integrates the functions of conveying, metering, stirring and feeding in one, which can improve the production efficiency and mixing quality to a certain extent. However, the existing full-automatic mixing system generally has the problems of high cost and complex maintenance, which limits its wide application.
