APPARATUS FOR COATING CU POWDER USING SCREW ROTATING AND PNEUMATIC PRESSURE

摘要

The present invention relates to an apparatus to coat copper powder using a screw rotating and a pneumatic pressure, comprising: a powder supply unit (10) to be supplied with copper powder through an upper opening; a driving unit (20) provided on one side of a lower part of the powder supply unit (10); a powder transporting unit (30) respectively connected to the powder supply unit (10) and the driving unit (20); a powder discharging unit (40) discharging copper powder supplied by a connection to the powder transporting unit (30); a nozzle container (50) to receive copper powder discharged from the powder discharging unit (40); and a pneumatic pressure regulator (60) to precisely adjust the pneumatic pressure while in connection to the powder discharging unit (40). A screw rotating type is used to transport copper powder supplied from the powder supply unit (10) to the powder discharging unit (40).
