Abstract
A recirculation system for ink or other material, fed to a printing head, in particular of the inkjet type, includes a recirculation container associated with a printing head and translatable along a predefined printing stroke together with the printing head. The recirculation container has, in its interior, anti-sloshing devices of the ink or other material.
Claims14
A system for recirculation of ink or other material, fed to a printing head, comprising:
- one or more recirculation containers associated with a printing head and translatable along a predefined printing stroke together with the printing head;
- and
- anti-sloshing devices of the ink or other material contained within the one or more recirculation containers,
- wherein the one or more anti-sloshing devices comprise walls or structural elements having a predetermined extension and a predetermined shape, even different from each other, which are housed inside at least part of an internal chamber of the one or more containers and define impediments or brakes to a free flow of a liquid material inside the one or more containers following a translation of the one or more containers together with the printing head, and
- wherein at least some of the anti-sloshing devices are made in one piece with walls of a corresponding container.
A recirculation system for ink or other material, fed to a printing head, comprising:
- a recirculation container associated with a printing head and translatable along a predefined printing stroke together with the printing head,
- wherein the recirculation container comprises a discharge outlet on a bottom thereof, the discharge outlet being provided at a lowest point of a bottom of the recirculation container, the lowest point being provided in correspondence with a bowl or well extension of at least a portion of the bottom of the recirculation container, the bowl or well extension having a funnel shape converging toward an opening of the discharge outlet.
A recirculation system for ink or other material, fed to a printing head, comprising:
- a first container of the ink or other material, connected to a supply circuit and provided upstream of the printing head;
- a second container for the ink or other material, connected downstream of the printing head;
- a first recirculation sub-unit for generating a first flow of the ink or other material from the first container toward the printing head and the second container;
- and
- a second recirculation sub-unit for transferring the ink or other material from the second container to the first container,
- wherein the first container and the second container and optionally anti-sloshing devices provided in the first container and the second container are made in one piece with an additive manufacturing process.
