A compact ink drying apparatus is capable of drying ink ejected to a resin substrate. The ink drying apparatus has a hot air dryer, a hot air supplying part, and an exhausting part. The hot air dryer has a drying furnace, a substrate conveying path formed as a spirally shaped path in the drying furnace, and substrate drying ducts blowing hot air to a surface of a resin substrate on which ink is ejected conveyed along the substrate conveying path to heat ink and exhausting water vapor generated by heating of ink. The hot air supplying part is outside the drying furnace and supplies hot air into the substrate drying ducts, and the exhausting part is outside the drying furnace and exhausts air in the drying furnace through the substrate drying ducts.

Ink drying apparatus for drying ink by heat after printing

A drying device H is provided with: a first heating roller partand a second heating roller partthat guide a printed object X and are capable of heating the printed object X; a first heating partthat is formed so as to be opposed to the outer circumferential surface of the first heating roller partand a second heating partthat is formed so as to be opposed to the outer circumferential surface of the second heating roller part, wherein after the printed object X has been guided to the first heating roller parton the upstream side, it is guided to the second heating roller parton the downstream side, with the setting temperature of the second heating roller partbeing made higher than the setting temperature of the first heating roller part, and an ink-jet printing device I equipped with such a heating device.

A heating drum, which guides a long-sized medium and also heats and dries the medium, includes a cylinder-shaped main body part, disc-shaped limb parts attached to the end parts of the main body part, and a shaft core attached to the limb parts. On an edge of an inner circumferential surface of the main body part, a cut-out part extending in the circumferential direction is formed. A groove part also extending in the circumferential direction is formed on the inner circumferential surface on an inner side from the cut-out part of the main body part. The cut-out part and the groove part are in parallel with each other, and the limb part is fitted to the cut-out part. A claw part is fixed to the limb part by a fitting tool, so that a hook part of the claw part is freely movably fitted to the groove part.
