  • Granulating Device Die, Granulating Device Cutter Blade Holder, Granulating Device Cutter Blade Unit, Resin-Cutting Device, Granulating Device, and Resin Pellet Manufacturing Method
    Publication number: 20240131750
    Abstract: Provided are a granulating device die, a granulating device cutter blade holder, a granulating device cutter blade unit, a resin-cutting device, and a granulating device, in all of which an increase in size is suppressed even when the processing amount is increased. The die (10) includes a bottom surface (10B), an upper surface (10A) having a radius smaller than a radius of the bottom surface (10B), a side surface (10C) that connects an outermost peripheral portion of the bottom surface (10B) and an outermost peripheral portion of the upper surface (10A), and a plurality of die holes (11) that discharge a resin raw material, the die holes being defined in the side surface (10C).

  • Filter device
    Patent number: 11529581
    Abstract: A negative pressure-side flow path having a negative pressure-side filter and a positive pressure-side flow path having a positive pressure-side filter are connected in parallel between a first port and a second port, and a shuttle valve is installed between the negative pressure-side flow path and the positive pressure-side flow path, and the first port, thus when a negative pressure is supplied to the first port, the first port is caused to communicate with the second port through the negative pressure-side flow path, and when a positive pressure is supplied to the first port, the first port is caused to communicate with the second port through the positive pressure-side flow path.
