Theory of Operation
The 300 ml Cartridge Pusher 98022 is used to dispense Loctite® medium viscosity
adhesive from 300 ml cartridges. The cartridge pusher is a front loaded, freestanding
device that can be coupled with a Loctite® Single Function Controller 98023, Three
Function Controller 98024 or integrated into an existing work cell.
Pressurized air is supplied to the air regulator. The air regulator controls the air
pressure that flows into the ram cylinder. A hand lever, pneumatic, three-way valve
channels the pressurized air into the pneumatic cylinder. The hand lever controls the
direction of travel of the piston within the air cylinder. Moving the hand lever down*,
toward the cartridge sleeve, causes the piston to move forward pressing product out of
the 300 ml cartridge through a product feed line. Moving the hand lever up*, toward
the air cylinder, causes the piston to retract. ( * Refers to unit mounted in vertical
orientation.)
The amount of product dispensed is controlled by three main factors:
•
Amount of pressure pushing on the piston.
•
Length of time a shut off valve remains open
•
Dispense needle size – length and orifice diameter
