Dynamic mixer dispense valve for two-component high-viscosity high-ratio compounds

A dynamic mixer dispense valve for use in combination with metered supplies of a base component and an accelerator component to provide on demand dynamic mixing and dispensing of a mixed compound formed of the base component and accelerator component, said dynamic mixer dispense valve comprising:

• first and second pneumatically controlled valve assemblies having first and second material inputs for receiving supplies of base component and accelerator component respectively each operating in an open configuration allowing base component and accelerator component to flow into said first and second valve manifold passages respectively or a closed configuration in which flow of base component and accelerator component is prevented;
• a combined cartridge manifold and valve manifold each defining first and second for communicating with said first and second valve manifold passages;
• first and second pneumatic valve actuators coupled to said first and second valve assemblies respectively each operating in response to a pneumatic input to configure said first and second valve assemblies into either said open configuration or said closed configuration;
• a cartridge retainer joined to said cartridge manifold defining a cartridge retainer interior and a cartridge discharge outlet;
• a cartridge coupled to said cartridge manifold and supported within said cartridge retainer interior defining an interior mixing chamber and a valve seat in communication with said cartridge discharge outlet;
• a mixer impeller defining a plurality of mixer blades and a valve cone;
• an impeller drive apparatus having a rotational power coupling and an impeller drive shaft, said impeller drive shaft being operatively coupled to said mixer impeller to rotate said mixer impeller within said interior mixing chamber and being slidably movable;
• and
• a pneumatic mixer actuating apparatus coupled to said impeller drive shaft operating in response to a pneumatic input to slidably move said mixer impeller to either a closed position in which said valve cone is seated within said valve seat to prevent material flow through said cartridge discharge outlet or to slidably move said mixer impeller to an open position in which said valve cone is spaced from said valve seat allowing material flow through said discharge outlet.

A dynamic mixer dispense valve for use in combination with metered supplies of a first component and a second component to provide on demand dynamic mixing and dispensing of a mixed compound formed of the first and second components, said dynamic mixer dispense valve comprising:

• a first pneumatically controlled valve supplying a first controlled flow of said first component;
• a second pneumatically controlled valve supplying a second controlled flow of said, second component;
• a manifold coupled to said first and second pneumatically controlled valves;
• a disposable mixer cartridge, coupled to said manifold, defining an interior mixing chamber and having a rotatable mixer impeller supported therein, said interior mixing chamber further defining a cartridge discharge outlet;
• impeller drive, apparatus coupled to and rotating said mixer impeller within said interior mixing chamber;
• and
• cartridge discharge outlet closure apparatus operating to provide direct closure of said cartridge discharge outlet and prevent compound flow therethrough.
