During initial state, the locating lever supports and leans on base lower part department, and casing and driving roller are stable contact under this state.
When the positioning rod is pulled out, the positioning rod is separated from the lower part of the base, the base swings around the hinged part of the base and the rack, and the swinging base can enable the shell to be separated from the transmission roller.
Then, the driving piece drives the plug to extend out, and the shell positioned on the plug extends out, so that the shell is positioned at a position which is convenient to take.
In the centrifugal mixer, the base has a plate-like guide plate, and the piston rod of the cylinder is inserted into the guide plate.
The plug can be prevented from inclining under the action of the guide plate.
Compared with the prior art, this centrifugal mixer can make the casing that has multiple material smoothly rotate through driving piece two, consequently, its misce bene's stability is than higher, enables multiple material by intensive mixing in this mixer.
Meanwhile, the first driving part and the second driving part are close to the shell, the structure is compact, and the practical value is high.
