Embodiment Construction

[0051] Following the reference numerals used in the figures, the system for cleaning inkjet print heads comprises a support structure 21 holding a main barrel filled with a liquid solvent up to a height sufficient to cover the The lower jetting part of the ink print head 16 to be cleaned within the barrel 25, in which there are a plurality of piezoelectric devices, not shown in the figure, responsible for regulating and applying the ink jets.

[0052]In order to adjust the optimum solvent level in the main tank 25, a height control device 17 located in the main tank 25 has been provided, so that the excess liquid solvent in the main tank is emptied into the height tank 13 through the height control device 17 to prevent ink The printhead 16 is wetted and this solvent is prevented from mixing with the pressurized recirculated solvent which passes through the interior of the ink printhead 16 in both circulation directions for better and more efficient cleaning. The control device...

Abstract

A system for cleaning inkjet print heads intended to clean these print heads by means of a pressurized fluid selected from liquid solvents and gaseous fluids such as air. Pressurized fluid is passed through the various spaces within the ink printhead through which ink would normally flow when jetting, so that this path is taken in both circulation directions for much more efficient cleaning. For cleaning, the ink print head is placed in the main tank such that the lower part of the ink print head is soaked in a liquid solvent contained in said first tank, which includes, among other elements, a Height control device for optimal height of liquid solvent in main barrel.

Description

technical field [0001] As expressed in the title of this application document, the present invention relates to systems and methods for cleaning inkjet printheads for industrial decoration of various items. [0002] Industrial decoration is applied on ceramics and other products where the surface to be decorated is large and uses inks which, due to their chemical composition, tend to clog the print head relatively frequently. [0003] Due to the high cost of these print heads, it is important to have the best means for cleaning the interior of the print head to unclog the print head, which constitutes an undeniable advantage. [0004] It is thus an object of the present invention to achieve optimal cleaning of these print heads at a high level of efficiency and at low cost. Background technique [0005] Currently, when an ink printhead is clogged, common solutions include disconnecting the ink inlet tube and applying a liquid solvent, usually of the organic type, with a syr...
