Toner powder surface structure homogenizing method for toner powder filling system, involves homogenizing surface structure by heated filling device i.e. filling nozzle, by heating effect of heating coil

摘要

The method involves homogenizing a surface structure of a toner powder by a heated filling device i.e. filling nozzle, by a heating effect of a heating coil, where the filling nozzle is double walled. The toner powder is shock-cooled after filling process, so that the surface structure is preserved in a homogenizing state. The heating coil is concentrically arranged within a double walled intermediate space, and is wound over an entire nozzle region.
