When the reciprocating motor 13 is running, the threaded rod 14 rotates, and the threaded rod 14 is screwed with the threaded tube 15, so that the piston 26 slides on the inside of the metering cylinder 10, and the negative pressure inside the metering cylinder 10 draws the additive through the additive input pipe 12. After that, the stirring motor 5 is running, and the speed is reduced by the reducer 6, so that the rotating shaft 7 rotates, driving the stirring blade 8 to stir the oil, and at the same time, the reciprocating motor 13 reverses to make the piston 26 slide down, and the additive is discharged into the active oil through the output head 11, so that it is quickly diffused.

[0025] It also includes a hinge 16 and a barrel cover plate 17. The front side of the top of the transfer barrel 1 is movably connected to the bottom side of the barrel cover plate 17 through the hinge 16. When the barrel cover plate 17 is closed under the constraint of the hinge 16, the interior of the transfer barrel 1 can be protected and the reliability can be improved.

When the reciprocating motor 13 is running, the threaded rod 14 rotates, and the threaded rod 14 is threadedly matched with the threaded tube 15, so that the piston 26 slides on the inner side of the quantitative cylinder 10. When the piston 26 moves up and down, it can be connected to the connecting line 22, and the connecting line 22 acts on the wire encoder 21 to output signals, which is convenient for precise control. The internal negative pressure of the quantitative cylinder 10 draws additives through the additive input pipe 12, and then the stirring motor 5 runs, which is decelerated by the reducer 6, so that the rotating shaft 7 rotates, driving the stirring blade 8 to stir the oil. At the same time, the reciprocating motor 13 reverses and runs, causing the piston 26 to slide down, discharging the additive through the output head 11 into the active oil, thereby quickly diffusing it.
