Description

Technical Field

[0001] The invention relates to a high-precision color mixing machine. Background Art

[0002] The color adjustment of objects such as glass glue needs to be carried out in a sealed atmosphere. For glass glue with lighter colors, the ratio between the master color paste and the base material is large (that is, the proportion of the base material is large). The existing color mixing machine that directly mixes the master color paste with the base material is difficult to mix the master color paste and the base material evenly. In order to achieve uniform mixing, the prior art usually uses diluents such as silicone oil to dilute the master color paste in a non-sealed state. When coloring light-colored glass glue, the content of the diluent is high, which affects the performance of the glass glue. In addition, the prior art needs to use a diluent to first mix 6 kinds of master color pastes of black, iron red, yellow, bright red, blue, and green into 12 kinds of diluted color pastes of black, light gray, dark gray, iron red, light iron red, yellow, light yellow, medium yellow, etc., and then mix them with the base material.
