Title: Continuous kneading device
Inventor: SATOU TADASHI
IPC: B29C48/405
Filed: 1980-10-25
Abstract: PURPOSE:To make the controlling of the degree of kneading possible while maintaining the rate of kneading constant by disposing plural pieces of screws of different shaft diameters in the cylinder barrel of a continuous kneading device and making the number of revolutions of the screws variable. CONSTITUTION:Three pieces of screws 2, 3, 3 are disposed in a cylinder barrel 1 with the screw 2 as a center, and are revolved in the same direction in the state of mutual intermeshing of the flights 6, 7, 7 of the respective screws. In this case, the diameter of the shaft 4 of the central screw 2 is made smaller than the diameter of the shafts 5, 5 of both side screws 3, 3. Since the greater part of the material conveyed under agitating and kneading are kneaded by the central screw 2, the rate of kneading is constant if the number of revolutions of the screw 2 is kept constant. Controlling of the degree of the kneading of the materials to be kneaded is easily accomplished by changing the number of revolutions of both end screws 3, 3.
