Abstract

The invention relates to the technical field of liquid paint production, in particular to an automatic feeding system for water-based paint, and a method for automatically feeding to a reaction kettle. The automatic feeding system comprises a measuring tank used for weighing the mass of liquid materials to be mixed, the reaction kettle used for providing a reaction space for the liquid materials to be mixed, a blending pipe unit used for providing a channel, through which the liquid materials to be mixed can be moved to the reaction kettle, for the liquid materials to be mixed in the measuring tank, a vacuumizer used for forming negative pressure in the reaction kettle so as to enable the liquid materials in the measuring tank to be transferred into the reaction kettle, an electromagnetic valve used for controlling the connection and disconnection between the measuring tank and the reaction kettle, and an industrial personal computer used for controlling the start and stop of the electromagnetic valve and the vacuumizer. The vacuumizer and the industrial personal computer are arranged, so that the reaction kettle is automatically fed with the materials in the measuring tank; furthermore, the problems that in the prior art, the feeding speed is slow, and residue exists in the measuring tank or a pipeline can be solved.

Description

technical field [0001] The invention relates to the technical field of liquid paint production, in particular to an automatic feeding system for water-based paint and a method for automatically feeding materials into a reactor. Background technique [0002] At present, the feeding system of the existing water-based paint production line in the market is usually: the metering tank is connected to the material source, and at the same time the metering tank is connected to the reactor, and the reactor is placed under the metering tank; a solenoid valve is installed between the metering tank and the reactor. The liquid material in the metering tank is transported to the reaction kettle by its own gravity; the bottom of the metering tank is equipped with an electronic scale and a related feedback system for accurate weighing of the lowered liquid material. The feeding procedure of the above-mentioned feeding system is as follows: after using the metering tank to weigh out one of ...
