Description

Technical Field

[0001] The utility model relates to the technical field of ink printing, in particular to an electrostatic ink absorption device for gravure dots of printed products. Background Art

[0002] The ink in the plate mesh must be transferred to the substrate under greater pressure. Therefore, the pressing force of gravure printing is greater than that of relief printing and other printing methods. Nevertheless, when the surface of the paper is relatively rough, the ink in the mesh is difficult to fully contact the paper, and the ink cannot be transferred to the substrate well, resulting in poor reproduction of white spots or fine lines in the printed images. Although increasing the pressure can improve the transferability of the ink. A Chinese patent discloses an electrostatic ink suction device (authorization announcement number CN206999831 U), which is a patented technology. An electrostatic ink suction device has a paper belt, and the upper end of the paper belt is provided with an impression roller, and the lower end is provided with a printing plate roller. The upper end of the impression roller is provided with a back pressure roller matched therewith, and an electrostatic electrode device is provided at the upper right side of one end of the impression roller. The structure is simple, and the ink transfer rate is much higher than the ink conversion rate under normal pressure, which not only makes the fine layers of the printed product well reproduced, but also can reduce the printing pressure, thereby achieving a better ink printing effect, especially suitable for printing of rough surface materials. This patented technology solves the problem that the increase of pressure has a certain limit, otherwise it is easy to damage the rubber layer of the impression roller or cause the printing material to deform.

[0003] However, in the prior art, when the concave plate dots are electrostatically absorbing ink, the static electricity content of the ink inside the ink box and the ink during inking is not easy to cause uneven depth during printing. It is necessary to solve the problem that the static electricity content may increase in a cycle after one inking.

[0004] Therefore, those skilled in the art provide a printing product gravure dot electrostatic ink absorption device to solve the problems raised in the above background technology. Utility Model Content

The positioning slides are restricted inside the ball bearing grooves of the positioning side frames through the movement of the ball bearings.

[0012] The two positioning slides are respectively mounted on the moving belts of the two positioning transmission structures.

[0020] Technical effects and advantages of the utility model:

[0021] 1.

The stability and accuracy of the printing plate during the printing process help improve the printing quality. Starting the bidirectional motor 1 can drive the bidirectional screw to rotate, and then adjust the position of the positioning side frame through the screw transmission. This design allows the operator to quickly and conveniently adjust the position of the printing plate to meet different printing needs.

[0022] 2. After the ink in the ink storage box is treated by the electrostatic discharger, the static electricity in the ink increases, which helps to improve the adhesion and uniformity of the ink on the printing plate.
