Problems solved by technology

A disadvantage of the prior art is that the interior of the print head forms a structural cavity through which the ink jet traverses, which cavity has protrudingly arranged electrodes therein as well as their holders and electrical connections, which are connected to each other and to each other. Creates a large number of corners, edges and gaps with the walls of the cavity, making simple and thorough cleaning complicated, time-consuming and in some cases only partially thorough

Embodiment Construction

[0038] figure 1 Schematically shows the working principle diagram of the print head of the continuous working inkjet printer. Ink 30 is first pumped from storage container 2 by means of pump 3 via feed line 4 a into pressure chamber 5 located in print head 1 , at one end of which pressure chamber is mounted nozzle 6 . The pressure in the pressure chamber 5 is modulated by the modulation device 7 additionally installed on the pressure chamber, so that the ink jet 9 ejected from the nozzle 6 is split into individual ones of substantially the same size in a short distance after it is ejected. ink drop11.

[0039] Prior to splitting, the individual ink droplets 11 are provided with their respective charge by means of, for example, annular / frame-shaped / U-shaped charging electrodes 8 , which at least partially surround the ink jet. The ink droplet 11 then enters the electric field 21 along its flight path 100 , which is formed by means of the electrodes 20 a and 20 b of the plate ...

Abstract

The invention relates to a print head of a continuous ink jet printer comprising a housing (1) that holds the components of the print head and is made of at least two housing parts (1a, 1b) that can be separated and that are in particular fastened to each other in an articulated manner, wherein a cavity traversed by the produced ink jet is arranged between the housing parts, wherein an insert (50a, 50b) is arranged on each of the housing parts (1a, 1b) and a cavity traversed by the ink jet is formed between the joined inserts (50a, 50b), wherein those surface areas (51a, 52a / 51b, 52b) of a respective insert (50a, 50b) that bound the cavity merge seamlessly with each other and in particular form smooth surfaces without gaps, edges, or undercuts.

Description

technical field [0001] The invention relates to a print head for a continuously operating inkjet printer, having a housing for accommodating parts of the print head, the housing being composed of at least two separable housing parts, in particular hingedly fixed to each other, in the housing A cavity through which the generated ink jet passes is provided between the body parts. Background technique [0002] Inkjet printers in continuous operation for many years are used industrially to represent different products. The principle of operation of so-called continuous-duty inkjet printers is that the ink to be printed is fed from a storage tank via a pump at an overpressure into a pressure chamber located in a special print head, which has a surface on the side facing the object to be printed nozzle. The nozzle has an opening diameter, for example, in the range from 30 μm to 200 μm. [0003] The ink jets first emerge from the nozzles as continuous ink jets, but this is disad...
