This paper introduces a kind of mechanical structure and its control system, with which granular materials can
be put into mould with a higher leveling status, the mechanical structure adopts split type arrangement, its function is to
achieve the material removal and scraping, its control system is composed of a plurality of Mitsubishi PLC using masterslave
control method. The mechanism and control methods can be widely applied in automatic production lines, which
needs granular material into the mould quantitatively and passively wiped flatly.
