Abstract
Aspects of the present disclosure relate to a method and system. The method includes obtaining a spray gun platform (206) and a spray gun nozzle assembly (208). The method can include assembling the spray gun platform (206) and the spray gun nozzle assembly such that the nozzle gas inlet is coupled with the platform gas passageway (228). The method can also include coupling an adhesive cartridge (204) containing the adhesive to the nozzle liquid inlet. The adhesive cartridge (204) is configured to be pressurized from a gas source. The method can also include activating a trigger of the spray gun platform (206).
Claims20
A system, comprising:
- a spray gun nozzle assembly comprising a nozzle body portion having a nozzle gas passageway and a nozzle liquid passageway formed therein, the nozzle gas passageway is formed between a nozzle gas inlet and a nozzle gas outlet, the nozzle liquid passageway is formed between a nozzle liquid inlet and a nozzle liquid outlet, the nozzle body portion comprises a first connector format at the nozzle liquid inlet, wherein the nozzle liquid inlet and the nozzle gas inlet are arranged obliquely relative to each other:
- an adhesive adaptor having a first end configured to form a fluid-tight connection with the nozzle liquid passageway, the adhesive adaptor having a first adaptor opening formed therein at the first end and a second adaptor opening formed therein opposite of the first adaptor opening at a second end, the first adaptor opening is configured to form a fluid-tight seal with the nozzle liquid inlet;
- and
- an adhesive cartridge container comprising a container body portion further comprising a first container opening and an adhesive cartridge container gas inlet, wherein the first container opening is configured to couple with the second adaptor opening, the adhesive cartridge container gas inlet is configured to receive pressurized gas, the adhesive cartridge container is configured to receive an adhesive cartridge containing an adhesive:
- wherein the system, when assembled, is configured to dispense an adhesive having a viscosity of at least 4000 centipoise.
A method, comprising:
- obtaining a spray gun platform and a spray gun nozzle assembly, wherein the spray gun nozzle assembly is detachable from the spray gun platform,
- wherein the spray gun nozzle assembly comprises a nozzle liquid passageway formed between a nozzle liquid inlet and a nozzle liquid outlet, and a nozzle gas passageway formed between a nozzle gas inlet and a nozzle gas outlet, wherein the nozzle liquid inlet and the nozzle gas inlet are not arranged along the same axis or coaxially,
- wherein the spray gun platform comprising a platform gas passageway formed therein, wherein the platform gas passageway is configured to fluidically couple to a gas source, wherein the nozzle gas inlet is configured to releasably couple with the platform gas passageway;
- assembling the spray gun platform and the spray gun nozzle assembly such that the nozzle gas inlet is coupled with the platform gas passageway, wherein the nozzle liquid outlet is controlled by a needle valve on the spray gun platform, the spray gun platform is not configured to contact an adhesive except through the needle valve;
- coupling an adhesive cartridge containing the adhesive to the nozzle liquid inlet, wherein the adhesive cartridge is configured to be pressurized from the gas source;
- activating a trigger of the spray gun platform, wherein activating the trigger causes the needle valve to open and thereby dispensing the adhesive through the nozzle liquid outlet;
- removing the spray gun nozzle assembly from the spray gun platform.
