  • Patent number: 8714806
    Abstract: An input shaft of a sealed kneading apparatus and an output shaft of a drive apparatus can be coupled together in a mutually eccentric state of both shafts and the apparatus life is prolonged. A coupling apparatus 6 for coupling between an input shaft 16 of a batch type kneading apparatus 1 and an output shaft 19 of a drive apparatus 2 for driving the kneading apparatus 1, the coupling apparatus 6 comprising a gear coupling section 5, the gear coupling section 5 being capable of coupling the input shaft 16 of the batch type kneading apparatus 1 and the output shaft 19 of the drive apparatus 2 with each other in a mutually eccentric state of both shafts, gears 24 meshing with other so as to slide relatively in the face width direction with rotation of the gear coupling section 5, and an oil bath type lubricating section 46 for lubricating the gears 24.

  • Patent number: 5607703
    Abstract: A roller head extruder unit includes an extruder unit, a pair of calender rollers arranged forward of an exit opening of the extruder unit and supported for rotation by a support frame mounted securely with respect to the extruder unit, and side guides arranged on either side of a space between the exit opening of the extruder unit and the calender rollers to thereby define a bank into which material for rolling is extruded. At least one of the upper and lower rollers is mounted for rotation in a roller housing supported by the support frame for limited movement in a direction perpendicular to the axis of the upper and lower rollers. The roller head extruder unit also includes a detection device for detecting the force with which this roller housing is caused to move as a result of accumulation of material in the bank.

  • Patent number: 5565219
    Abstract: A bank quantity adjusting device for an extruder capable of accurately controlling a bank quantity regardless of a difference in composition of a material to be extruded. The bank quantity adjusting device includes a pressure sensor 13 for detecting a bank pressure between an outlet 7 of an extruder body 1 provided with material extruding screws 3 and a roller die 2 provided before the outlet 7, and a control device 15 for controlling one or both of a screw speed and a roller die speed according to a difference between the bank pressure detected by the pressure sensor 13 and a set target pressure.

  • Patent number: 5433522
    Abstract: A hydraulic control device for a closed type kneader, including a sealing surface pressure applying circuit for applying a sealing surface pressure to a sealing device for sealing a rotor accommodated in a kneading chamber, a drop door driving circuit for controlling an opening and closing operation of a drop door for closing a bottom surface of the kneading chamber, and a power circuit for supplying a pressure oil to the sealing surface pressure applying circuit and the drop door driving circuit. The sealing surface pressure applying circuit is connected to a pressure oil supply line in the drop door driving circuit for a closed condition of the drop door. Accordingly, when the application of the sealing surface pressure is unnecessary, that is, when the drop door is opened, the sealing surface pressure is prevented from being applied to the sealing device, thereby extending the life of the sealing device.
