(FR) SYSTÈME D'ALIMENTATION EN ENCRE POUR DISPOSITIF D'IMPRESSION NUMÉRIQUE ET DISPOSITIF D'IMPRESSION NUMÉRIQUE COMPRENANT LEDIT SYSTÈME
Abstract
(EN)
Ink supply system (1) for digital printing device comprising: a supply tank (9) suitable for containing ink; a delivery tank (2), in fluid connection with said supply tank (9), suitable for containing ink; one or more delivery conduits (4) suitable for connecting said delivery tank (2) to one or more print heads (100) associatable with said supply system (1); first pressure adjusting means (10) suitable for controlling the pressure inside the delivery tank (2); a supply pump (6) suitable for moving ink from said supply tank (9) to said delivery tank (2); a first level sensor (7) suitable for performing the continuous reading of the level variations inside the delivery tank (2); wherein said supply pump (6) is continuously feed-back controlled on the basis of the reading of said first level sensor (7) for keeping a pre-defmed level inside said delivery tank (2).
