20090097350 | Kneader - One object of the present invention is to provide a kneader which can diminish wear of screws and a barrel while preventing the manufacturing process for the screws and barrel from becoming complicated. In this kneader, a pair of screws are rotated about respective axes thereof to knead a material to be kneaded which is introduced into a kneading space formed within a barrel. Each screw has such a shape generating deflection in a predetermined direction perpendicular to an arranged direction of the axes of the pair of screws during kneading of the material to be kneaded, and the kneading space has a shape such that a pair of accommodating spaces which accommodate each of the screws respectively are connected together so as to overlap each other partially in the radial direction, each accommodating space being formed in such a manner that the diameter thereof in the predetermined direction in which there occurs deflection of each screw is larger than in any other direction. | 04-16-2009 |

20100110822 | DEVICE AND METHOD FOR ADJUSTING THE DEGREE OF MIXING - The device for adjusting the degree of mixing according to the present invention is installed in mixing equipment equipped with a kneading/mixing screw for mixing material while feeding the material to a downstream side, wherein a gate member is moved relative to a portion of a circular section provided for the kneading/mixing screw so as to cause a change in the area of a flow path formed between the gate member and the portion of a circular section, thereby adjusting the degree of mixing of the material. Drive quantity changing means is disposed between the gate member and drive means. The drive quantity changing means is constructed so as to change the drive quantity, x, into the movement quantity, Δδ, in accordance with a profile such that a change rate of the movement quantity, Δδ, relative to the drive quantity, x, is made smaller when the degree of opening, δ, of the gate member is smaller and the change rage of the movement quantity, Δδ, relative to the drive quantity, x, is made larger when the degree of opening, δ, of the gate member is larger. Through such construction, it is possible to let the degree of mixing change at a constant change rate relative to the drive quantity of the drive means. | 05-06-2010 |

20120269024 | KNEADING SEGMENT AND KNEADING EQUIPMENT - A kneading segment kneads materials such that insufficiently kneaded portions would not remain as gel. The kneading segment is rotatably disposed on a kneading screw housed in a barrel having an inner cavity, and is provided with a kneading flight which kneads the material in the barrel by rotating according to the kneading screw's rotation. The top surface of the kneading flight is formed with a concaved cutout section. The cutout section is surrounded by two side surfaces, which face the axial direction, and a bottom surface, which is disposed between the side surfaces. The bottom surface of the cutout section is formed in a tilted planar shape in relation to the top surface. The opening of the cutout section, which faces one side of the rotational direction of the kneading screw, has a larger area than the opening which faces the other side. | 10-25-2012 |

20150355007 | APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT FOR ANALYZING FLUIDITY - An apparatus, method and computer program product for analyzing fluidity are provided which enable fineness and coarseness in a particle distribution pattern in an object to be restrained in analysis results and thus, the fluidity analysis to be conducted with high accuracy. The apparatus for analyzing fluidity, using a particle method, determines a velocity of each particle, based on particle information of a position of each particle and a physical state of each particle in the last time step, and determines a position of each particle in the current time step, based on the velocity determined. The apparatus for analyzing fluidity next rearranges, based on distances between particles arranged at the determined positions, each particle in the current time step so that the fineness and coarseness in the particle distribution pattern in a target for analysis is reduced. | 12-10-2015 |
