The invention discloses a metering and conveying method and device. The metering and conveying method comprises the following steps that S1, a feeding formula is obtained, the quality and the densityof various auxiliaries in the formula are obtained, the liquid level of the cylinder is obtained, the temperature change rate is obtained, the rotating speed of the cloth lifting wheel is obtained, and the rotating speed of the circulating pump is obtained; S2, the quality of the added auxiliary agents is obtained; S3, the auxiliary agents are pumped into the cylinder body through the booster pump, the rotating speed of the booster pump and the density of the auxiliary agent, the liquid level and the temperature change rate of the cylinder body, the rotating speed of the cloth lifting wheel, the rotating speed of the circulating pump and the quality of the added auxiliary agent are related; S4, whether the specified quality is added or not is judged, if yes, the step is skipped to the stepS5, and if not, and the step S2 is executed; S5, the feeding is ended. According to the metering and conveying method and device, the parameter can be adjusted in a self-adaptive mode.
