摘要： A powder coating apparatus capable of applying powder coating material into articles at high production rates while recovering oversprayed powder is provided. The apparatus may include a powder coating applicator that may form part of a circulation loop for powder coating material from a supply, through the applicator, and back to the supply. The powder coating apparatus may rapidly switch between applying powder coating material and circulating the powder coating back to the supply. In one embodiment, the applicator includes an inlet and a diverter having a first operating mode during which powder coating material flows from the inlet to a first coating material outlet for a coating operation, and a second operating mode during which powder coating material flows from the inlet to a second coating material outlet for a non-coating operation. The coating applicator may be reciprocated into and out of a container such as a tube, with powder sprayed by the applicator into the tube as the applicator is lanced into the tube, and with oversprayed powder which does not adhere to the interior of the tube being pulled back through the applicator as the applicator is withdrawn back out of the tube, for example. A densifier, or condensing device, may be used to remove air from the air entrained powder, and increase the powder to air ratio before the powder is sprayed from the applicator into the container.
摘要翻译：提供了一种能够以高生产率将粉末涂料涂覆到制品中同时回收过喷粉末的粉末涂覆装置。该设备可以包括粉末涂料涂布器，其可以形成用于粉末涂料材料的循环回路的一部分，所述粉末涂料材料从供应源经过涂布器返回到供应源。粉末涂覆设备可以在施加粉末涂料和将粉末涂料循环回到供应源之间快速切换。在一个实施例中，施用器包括入口和转向器，该转向器具有第一操作模式和第二操作模式，在第一操作模式期间粉末涂料从入口流动到用于涂布操作的第一涂料出口，在第二操作模式期间粉末涂料从进入第二涂料出口进行非涂布操作。涂料涂布器可以往复进入和离开诸如管的容器，当施用器被刺入管中时，通过施用器将粉末喷射到管中，并且过度喷涂的粉末不粘附到管内部例如，当涂药器从管中退出时，通过涂药器拉回。可以使用密实器或冷凝装置来从夹带空气的粉末中除去空气，并在将粉末从涂敷器喷射到容器中之前增加粉末与空气的比例。
