Abstract:
A line inkjet head cleaning apparatus for effectively cleaning a long line inkjet head includes a wiper fixer extending in a longitudinal direction of a line inkjet head as a cleaning target and having a predetermined width in a vertical direction, a cleaning wiper being fixed to an upper end thereof, a cleaning solution tank having a predetermined volume accommodating the wiper fixer and having an opening in an upper surface, and a driver that vertically moves the wiper fixer between a cleaning solution in the cleaning solution tank and the line inkjet head as a cleaning target positioned above the opening.
Abstract:
Provided is a granular material which generates no harmful gas at the time of pouring, reduces a gas defect as one of casting defects, and is readily reusable after pouring, in the manufacture of a three-dimensional laminated and shaped mold. This granular material is a granular material for use in a three-dimensional laminated and shaped mold manufacturing apparatus, and includes magnesium sulfate. The amount of magnesium sulfate included in the granular material is 1 to 10 pts·mass with respect to 100 pts·mass of the granular material. The amount of water included in the granular material is 0.1 mass % or less except for crystallization water of magnesium sulfate.
Abstract:
This invention quickly supplies a predetermined amount of powder from a hopper to a recoater. A powder supply apparatus includes, as its feature, a hopper, a powder spreader, a powder replenisher, and a pivoting unit. The hopper of the powder supply apparatus stores a powder. The powder spreader spreads the powder on a shaping surface. The powder replenisher of the powder supply apparatus is provided between the hopper and the powder spreader, and replenishes the powder spreader with a predetermined amount of powder. The pivoting unit of the powder supply apparatus causes the powder replenisher to pivot.
Abstract:
The spread amount of a powder to be spread from a powder recoater is adjusted. The powder recoater according to this invention includes a hopper that stores a powder. The powder recoater according to this invention also includes a cylindrical powder supplier that has a side surface close to or in contact with the bottom surface of the hopper and includes a supply path for the powder. The powder recoater according to this invention further includes a pivoting unit that causes the powder supplier to pivot. In the powder recoater according to this invention, the center axis of the supply path crosses the center axis of the powder supplier.
