[0002] EPS foam plastic is a lightweight material made of polystyrene resin as the base material, with the addition of foaming agents and other auxiliary materials, and is produced by heating and foaming. It has the advantages of being lightweight, having a low thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, and being inexpensive and of high quality.

Start the first motor 2006, which drives one of the rotating rods 2003 to rotate. In conjunction with the synchronous pulley 2007 and synchronous belt 2008, the pair of rotating rods 2003 rotate simultaneously, driving several first stirring rods 2005 to rotate simultaneously, thus performing preliminary stirring of the various raw materials. After stirring is complete, activate a pair of telescopic rods 2011, which shorten and pull the baffle 2009 downwards to facilitate the conveying of the pre-stirred raw materials to the mixing chamber. Inside the mixing chamber 3001, the second motor 3009 is then started, causing the second motor 3009 to drive the active bevel gear 3011 to rotate.
