Abstract

The recirculating printer (1) comprises: - a print head (2); - a supply assembly (3) for sending the printing fluid (F) to the print head (2); - a recirculation unit (4) for the movement of the printing fluid (F) inside the print head (2) comprising: - a first container (5); - a second container (6); - a first recirculation assembly (7) adapted to move the printing fluid (F) from the first container (5) towards the second container (6) passing through the print head (2); - a second recirculation assembly (8) adapted to move the printing fluid (F) from the second container (6) towards the first container (5) without passing through the print head (2); - an auxiliary recirculation assembly (21) adapted to direct the printing fluid (F) alternately towards the first container (5) or the supply assembly (3).

Abstract

The digital printer (1) for the decoration of manufactured articles (M) comprises: one base frame (2); one line of forward movement (3); one supporting assembly (4); one movement unit (6) defining a movement path (P1, P2, P3, P4) extending along a first stretch (P1), a second stretch (P2) and a third stretch (P3); a plurality of printing assemblies (7) mounted on the movement unit (6) and movable in a sliding manner along the movement path (P1, P2, P3, P4); wherein the movement unit (6) comprises: one transfer element (17a) movable along the third stretch (P3) between one first transfer position, wherein it is aligned with the first stretch (Pl), and one second transfer position, wherein it is aligned with the second stretch (P2); movement means (18a) adapted to move the transfer element (17a) between the first transfer position and the second transfer position.

Abstract

The digital printer (1) for the decoration of slab-shaped manufactured articles (M) comprises: - a basic frame (2); - a line of forward movement (3) adapted to move slab-shaped manufactured articles (M) along a direction of forward movement (A); - a supporting set (4) liftable and lowerable with respect to the line of forward movement (3); - a guidance unit (6) arranged at least partly on top of the line of forward movement (3) and defining a movement path (P1, P2, P3, P4); - a plurality of printing sets (7) mounted on the guidance unit (6) and movable in a sliding manner along the movement path (P1, P2, P3, P4), individually and independently of each other, between a working position, wherein the printing sets (7) are arranged on top of the line of forward movement (3) for dispensing ink on the slab -shaped manufactured articles (M), and at least one home position.
