Embodiment 1

[0023] Embodiment one: see appendix figure 1 And attached figure 2 , On the printing head plane 107 of the inkjet print head, there are fine ink ejection holes 101, thickness ink ejection holes 102, right ink ejection holes 103, left ink ejection holes 104, rear ink ejection holes 105 and front ink ejection holes 106.

[0024] The fine ink ejection hole 101 and the thickness ink ejection hole 102 are vertical ink ejection holes, and the ink drop ejection direction is perpendicular to the printing surface 120; the right ink ejection hole 103, the left ink ejection hole 104, the rear ink ejection hole 105 and the front ink ejection hole 106 is an inclined ink ejection hole, and the ejection direction of the ink drop forms an angle of 45 degrees with the printing surface 120 .

[0025] Because the ink droplets ejected from the fine inkjet hole 101 are thinner than the ink droplets ejected from the thick inkjet hole 102, the fine inkjet hole 101 is used to print the edge positio...

Embodiment 2

[0033] Embodiment two: see attached image 3 to attach Figure 5 , the printing head plane 207 of the inkjet printhead is distributed with fine inkjet holes 201, thickness inkjet holes 202, and the opening surface 208 is distributed with right rear inkjet holes 203, left front inkjet holes 204, right front inkjet holes 205 and The left rear ink jet hole 206.

[0034] The fine ink ejection hole 201 and the thickness ink ejection hole 202 are vertical ink ejection holes, and the ink drop ejection direction is perpendicular to the printing surface 220; The ink hole 206 is an inclined ink ejection hole, and the ink drop ejection direction forms an angle of 45 degrees with the printing surface 220; the triangular groove on the print head plane 207 provides an opening surface 208 perpendicular to the ink drop ejection direction for the inclined ink ejection hole, Therefore, it is ensured that the openings of the inclined ink ejection holes are circular and axisymmetric along the e...

Abstract

The invention discloses an inkjet printing head. When an inkjet printing head is used to print a covering film, the printing of a fine covering film edge, a sufficient thickness and a convex three-dimensional surface is needed. An existing nozzle has a single vertical spraying direction, the same spraying amount of spraying holes and the limited spraying adjustment range of the spraying holes, and multiple requirements in printing the covering film can not be satisfied at the same time. The invention provides the following solution that an inkjet printing head comprises spraying holes with different spraying amounts and different ink drop spraying directions, different spraying holes are in cooperated working, a small ink drop is used for printing a smooth edge, a large ink drop is used for printing the thickness, and an ink drop which is sprayed in an inclined way is used for printing a side face.

Description

technical field [0001] The present invention relates to an inkjet print head, and more particularly to an ink jet hole on the inkjet print head. technical background [0002] Inkjet printing has been widely used as a printing method for images and texts. With the development of inkjet printhead technology, the printing efficiency of inkjet printheads has been continuously improved, the printing effect has become more and more delicate, and the printing colors have become more and more abundant. ; Inkjet printing can also be applied to thin film printing and three-dimensional printing. However, the current inkjet printing head has a single ink ejection hole: the ejection direction of ink droplets is a single direction perpendicular to the printing surface, and the ink ejection amount of the ink ejection holes on the same print head is the same. Although the actual ink ejection volume can be adjusted during printing, the adjustment range is limited. In order to further incre...
