摘要： A spray gun for applying powder to coat a work piece uses triboelectric and optionally a corona discharge electrode to charge powder particles electrostatically. The gun communicates with a source of pressurized air through a handle with an air valve controlling flow of the air. Powder in a container in fluid communication with the air flow is fluidized and entrained when the valve is opened. A nozzle with an internal surface defining a passageway to an open end communicates with the powder container. The internal surface of the nozzle frictionally imparts a net electrical charge of a first polarity to part of the powder by frictional contact during spraying. A plurality of discrete tubes are disposed in the central passageway and impart a net electrical charge of a second polarity to another part of the powder due to frictional contact as that part flows around and through the tubes. The powder then exits the nozzle, passes the corona discharge electrode which produces a corona that charges the powder with an electrical potential in the range from about 8 kV to about 20 kV.

摘要： Apparatus for powder spray coating comprises means (4) for electrostatically-charging powder entrained in air, a conduit (6) for transporting the electrostatically charged powder from the charging means (4) to an internal chamber (12) in a spray head (8), the spray head (8) having at least one passage (16) from the internal chamber (12) to at least one nozzle (17) from which the powder is discharged, and a deflector (18) mounted externally of the spray head (8) and adjacent to the or each nozzle (17) to deflect the discharged powder into a flat spray pattern, the spray head (8) and the flat spray pattern being substantially symmetrical about a common longitudinal axis. The apparatus is particularly suitable for coating a large surface area, or a plurality of small objects hung in a planar array. Preferably multiple triboelectric type charging means (4) are used and a single pump is used to supply powder to the multiple charging means through a common distributor. After passing through the multiple charging means (4) the powder flows are then recombined and sprayed through a common nozzle.

摘要： Methods and apparatus are disclosed for spraying powder into the interior of welded hollow can bodies from a spray gun mounted to the welding arm of a can forming machine. The spray gun can either apply a stripe of highly charged powder on the welded seam areas of hollow can bodies, or can simultaneously apply a coating of powder having a first thickness on the longitudinally welded seam areas and a second thickness less than the first thickness on the remainder of the interior surface. Air is vented off from the powder flow being transported through the welding arm so that the powder to air ratio is increased. Air is introduced at the downstream end of the welding arm to provide a suction force to help draw the powder flow through the welding arm and to increase the velocity of the powder flow for better tribo charging of the powder in the gun and to improve spray pattern stability. A flow of cleaning air through the powder spray gun prevents powder from collecting on the front surface of an offset nozzle secured to the spray gun. The gun assembly is affectively grounded to prevent arcing, and has an exterior shape which has been geometrically configured to improve powder coating of the can.

摘要： An apparatus is operable to sequentially spray powder onto each workpiece of a plurality of workpieces. The powder flows from an improved nozzle assembly as a series of pulses. Accumulation of powder on surfaces in the nozzle assembly is retarded by conducting a flow of fluid (air) from a source of fluid pressure through openings in the surfaces in the nozzle assembly. Thus, a plurality of openings are formed in a side wall of the nozzle assembly to enable fluid to flow through the openings in the side wall into the flow path of air and powder through the nozzle assembly to retard accumulation of powder on an inner side surface of the side wall. An inner deflector has an end surface which faces toward the workpiece and on which powder tends to accumulate. A flow of fluid is conducted through openings in the end surface of the inner deflector to retard the accumulation of powder on the end surface of the inner deflector.

摘要： An apparatus for spraying powder coating material includes a rotatable turret which moves articles to and from a work station. A powder spray gun is operable to spray a pattern onto each of the articles in turn while the article is at the work station. The powder flows through the spray gun as a series of pulses. A diverter assembly is operable to divert a portion of each pulse of powder away from the nozzle to more sharply define the pulse. An excess powder collector draws a flow of powder away from the work station. A virgin powder container supplies powder to a powder collector container which supplies powder to a powder feed container which supplies powder to the spray gun. Sensors associated with the virgin, collector and feed containers ensure that a predetermined quantity of powder is maintained in each container. During transport of powder from the virgin and collector containers, the containers and their associated pumps are vibrated to facilitate the flow of powder. The powder spray gun is mounted on a three axis adjustment assembly to enable the powder spray gun nozzle to be accurately positioned relative to an article at the work station.

摘要： Apparatus for coating the endmost threaded section of a pipe with corrosion resistant powder coating material by rotating the pipe and spraying the section to be coated with electrostatically charged, air-entrained powder through two stationary nozzles, one of which is directed at the section to be coated, and the other of which is directed at the chamfered end of the pipe. To prevent overspray of the powder from contacting the pipe adjacent to the area to be coated, a pair of air nozzles are directed at the area of the pipe adjacent to the area to be coated.

摘要： A stream of carrier gas with powder particles is introduced at the feedingnd (2) of a powder pipe (1) in the direction of arrow (3) for coating workpieces. The material of the coating powder, of the powder pipe (1) and of displacement bodies (21, 22) built in the latter have different dielectric constants. At a certain distance from the outlet end (5) is mounted a charging device (12) provided with boosting electrodes (15) projecting inwardly and connected through a protective resistance (15) to a high-voltage supply (17). A rear counter-electrode (7, 26, 27) comprises an earthed conductive body (7). The displacement bodies (21, 22) accelerate the flow of powder particles. The latter come repeatedly in contact with the inner surface (11) of the powder pipe (1) and the displacement bodies (21, 22) communicating negatively charged particles (10) to them, after charge separation, whereas the positively charged particles (4) remain attached to the powder particles. The concentration of negatively (10) and positively (4) charged particles at opposite ends (2, 5) of the pipe is increased through the electrostatic field acting between the boosting electrodes (13) and the counter-electrode (7, 26, 27). The coating powder is thus so highly charged that an outer electrostatic field between a spraying electrode and the workpiece can be dispensed with.

摘要： A versatile spraying gun includes main tool and several attachment tools any one of which can be inserted in the main tool. Each attachment tool is designed to atomize powder particles that are to be sprayed on an article in accordance with a specific spraying method and atomization principle and method. The main common tool is comprised primarily of a body that defines a powder delivery channel and a coupling piece and discharge electrode located upstream in the delivery channel. The attachment tools have a flow guide member disposed axially within the delivery channel and an attachment piece for attaching the attachment tool to the coupling piece of the main tool. In some attachment tools, the flow guide member also houses a high voltage circuit and appropriate electrodes needed for electrostatic charging of the powder which passes through an electrical field set up between the electrodes.
