AI Technical Summary
Existing powder mixing devices have difficulty in achieving uniform mixing of two colors of powder during the stirring process, especially in localized areas where the proportions differ significantly.
The system employs a multi-stage screw conveyor and a motor-driven mixing device. By controlling the speed of the screw conveyor and rotating the motor, the plastic powder is mixed and dispersed multiple times. Combined with the beating action of the baffles, this ensures that the plastic powder is fully mixed in each stage of the tank.
It improves the mixing uniformity and stirring efficiency of the plastic powder, avoids excessive differences in the proportion of plastic powder in local areas, and enhances the mixing effect.
