[0027] Specifically, by connecting one end of the quantitative feeding valve 11 to the external storage tank and the external water supply pipe, the quantitative feeding valve 11 can be controlled to open when the raw materials needed for rubber additive emulsification are added, so that the various raw materials can be added quantitatively, and the addition process does not need to be observed and processed in real time, thereby reducing the tedious work steps of personnel, and during the addition process, the various raw materials are sent into the feeding inner cylinder 2 by the feeding pipe 12. At this time, the mixing motor 4 can be started, because the feeding inner cylinder 2 is rotatably installed in the emulsification kettle 1, and the drive shaft of the mixing motor 4 is connected to the feeding inner cylinder 2 through the transmission rod 5, so that the feeding inner cylinder 2 can be driven to rotate by the mixing motor 4.
