Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a manual plugging and unplugging device for a double planetary mixer. Background Art

[0002] When a double planetary mixer is stirring, different mixtures often need to be added during the stirring process depending on the materials to be stirred. The stirring barrel is often provided with a plug-in tube for connecting to an external conduit, and the mixture is injected from the conduit during stirring.

[0003] The connection and separation of the plug-in tube and the conduit are generally automatically connected by the rising of the mixing barrel. This connection method cannot guarantee the sealing effect. If leakage occurs during the mixing process, it will have a great destructive effect on the mixing work and even make the mixing work useless. Utility Model Content
