摘要:
Apparatus and methods for aligning a powder spray canopy of a powder coating booth with a fan plenum assembly so that a powder collector can be quickly aligned and simultaneously sealed to both the powder spray canopy and the fan plenum. The invention also relates to an improved filter cartridge and filter cartridge mounting assembly which allows for quick and easy mounting and dismounting of filter cartridges to the powder collector.
摘要:
A method and apparatus for forming and dispensing a coating material formulation or solution containing a liquid coating composition and a fluid diluent such as a supercritical fluid comprises a supply for the liquid coating composition, a supply for the fluid diluent, a mixer for combining the two components to form the coating material solution or formulation, and a control system for monitoring a parameter of the formulation which can be correlated to the fluid diluent content and/or liquid coating composition content of the formulation, and for monitoring the pressure of the formulation at selected locations within the system. The control system is effective to open or close the supply of fluid diluent and/or liquid coating composition in accordance with variations in the formulation parameter which is being sensed, and in response to pressure changes within the system, to maintain single or multiple phase coating material formulations, to account for changes in a parameter of the liquid coating composition and to ensure that the desired ratio of fluid diluent to liquid coating composition is maintained in the formulation which is supplied to coating dispensers for deposition onto a substrate.
摘要:
Apparatus and method for electrostatic charging of a container for an electrostatic coating operation includes a support member for supporting a container during an electrostatic coating operation with the support member comprising a non-metallic conductive material or electrically semiconductive portion that directly contacts a surface of the container. The electrically semiconductive portion comprises non-metallic, resistive or low conductivity material and is coupled to a source of electrical energy such that the container is electrostatically charged to an opposite polarity to offset or reduce electrostatic charge build up produced by the electrostatic coating operation.
摘要:
In an induction heater, preheated, pressurized air is further heated in the heating cabinet and also drawn into the coil tube via a suction fan. The simultaneous pulling and pushing of the twice-heated air through the tube provides superior air flow to pick up more moisture from the can ends being dried. The tube ends rest on upwardly concave collars and are held in place by gravity, with a single screw acting as a stop above to prevent upward movement. Removal requires only removing the single screw at each end then lifting the tube straight up out of the cabinet, which is facilitated by providing a hinged cover on the cabinet.

摘要:
Apparatus for spraying glass bottle mold bodies, such as blanks and rings in a molding machine, includes nozzles and spray guns mounted on a plate such that the nozzles are positioned to spray the mold bodies with a material such as a lubricant during normal operation of the machine and without shutting the machine down. The apparatus can be installed on an existing machine without changing the molding machine. Rings may be sprayed while in motion during normal machine operation. A nozzle is provided along with check valves to produce a tight conical spray pattern.
