Automatic wraparound type powder body paint device null of preheating

摘要

PURPOSE: To develop a method and apparatus in which in electrostatic powder coating of a preheated material to be coated, excessive powder (overspray paint) produced by scattering and dropping is regenerated effectively and mixed uniformly with new powder in an optional ratio to prepare proper coating powder, and the mixture is circulated automatically to be used. ;CONSTITUTION: The objective apparatus is composed of a recovery tank 3 for recovering excessive powder under a coating both 2, a recovered powder cleaner 4 which performs cracking, foreign matter removing, and iron removing continuously to make a recovered cleaning body Q, a new powder supply apparatus 5 which is installed separately, a powder mixing apparatus 6 in which new powder and recovered powder are mixed in an optional ratio to prepare uniform coating powder, a powder supplying apparatus 7 which pneumatically sends an optional amount of the coating powder to each electrostatic gun, and a controller which controls time and the length of time to synchronize apparatuses and actuations common to the apparatuses.;COPYRIGHT: (C)1996,JPO
