Apparatus for sealing and cleaning the ink discharge openings at an ink

The invention relates to a write head for ink printer devices comprising tubular ink channels which are surrounded over a part of their length by individually drivable small piezo tubes and which are situated proceeding between an ink supply part and the discharge openings of the write head. The ink channels applied to a carrier part form a pre-fabricatable channel block together with this carrier part. A channel plate is secured either to that side at which the ink channels end free or to the back surface of the carrier part. In one embodiment, the channel plate comprises a layer plate having through holes into which the free ends of the ink channels equipped with the small piezo tubes are pluggable. Transition channels for guiding the ink flow and the discharge openings of the write head for fashioned in further layer plates of the channel plate.

Write head for ink printer devices

For the contacting and for the fixing of tubular piezoelements or, more particularly, piezotubes, in the recording head of an ink printer, a tube holder, first contact elements, a clamping part into which the tube holder can be snapped, and second contact elements are disclosed. The tube carrier has cut-outs corresponding to the form and position of the piezotubes, into which the first contact elements can be placed. The clamping part has openings, into which the second contact elements are inserted. After the tube carrier has been snapped into place, the first and second contact elements, being held in correct position, are soldered.
