This utility model discloses a pre-feeding mechanism for modified
polyester aqueous dispersions, relating to the field of
polyester aqueous dispersion preparation technology. It includes a stirring drum, with a feeder connected to the top of one side of the stirring drum. A feed transfer roller is rotatably connected inside the feeder. A
drive motor is fixedly installed on the outer wall of one side of the feeder. A feeding trough is formed on the inner wall surface of the feeder near the stirring drum. The feeder automatically feeds material from the pre-storage drum by directly opening a feeding control valve on a feeding
pipe. The
drive motor rotates the feed transfer roller, transferring the material through the feeding trough into the stirring drum. A material replenishment
pipe facilitates replenishment of the pre-storage drum, ensuring sufficient material for operation. Feeding can be stopped by simply shutting off the
drive motor.
