[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 A printing press with an electrostatic ink absorption mechanism shown includes a bracket 1;

[0029] The ink tank 2 is fixedly mounted at the bottom of the bracket 1 and is used for inking the printing roller 4. A first driving motor 3 is fixedly mounted on one side of the bracket 1, and a printing roller 4 is fixedly mounted on one end of the first driving motor 3. A static eliminator 5 is arranged inside the bracket 1.

[0030] The embossing roller 14 is arranged inside the bracket 1 and is used for embossing the paper, and the embossing roller 14 is fixedly connected to the second driving motor 13;

[0031] The conductive rod 19 and the conductive brush 22 are arranged inside the bracket 1, and are used to conduct electricity to the embossing roller 14. The paper first passes through the static eliminator 5 to eliminate static electricity, and then is transported between the printing roller 4 and the embossing roller 14. Then, the electric field generated by the external high voltage electricity is introduced into the conductive rod 19 and the conductive brush 22, and the electricity is introduced into the embossing roller 14 through the conductive brush 22. The embossing roller 14 is set as a conductive rubber roller. Then, the embossing roller 14 isolates the paper and absorbs all the ink in the printing roller 4, forming the principle of electrostatic ink absorption.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, slide grooves 6 are provided on both side surfaces of the interior of the bracket 1, and a slider 7 is movably connected inside the slide groove 6. A movable frame 8 is fixedly installed on one side of the slider 7. When the movable frame 8 and the embossing roller 14 are raised and lowered in the bracket 1, the cooperation between the slider 7 and the slide groove 6 improves the stability of the embossing roller 14 during the raising and lowering process.

[0033] like Figure 3 As shown, the movable frame 8 is internally movably connected with a screw rod 9, the lower end of which is fixedly mounted with a first gear 10, one side of the first gear 10 is movably connected with a second gear 11, and one end of the second gear 11 is fixedly mounted with a handle 12. The screw rod 9 is driven to rotate through the meshing transmission between the first gear 10 and the second gear 11, so that the movable frame 8 and the embossing roller 14 can be adjusted in height within the bracket 1.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, connecting seats 15 are fixedly installed on both sides of the interior of the bracket 1, and a limiting groove 16 is provided on the rear surface of the connecting seat 15. A movable block 17 is movably connected to the interior of the connecting seat 15, and a bolt 18 penetrates one side of the movable block 17. By utilizing the limiting groove 16 provided inside the connecting seat 15, the height of the conductive rod 19 and the conductive brush 22 can be adjusted together with the embossing roller 14.

[0035] like Figure 1 and Figure 5As shown, a connector 20 is provided on one side of the outside of the conductive rod 19, a connecting block 21 is fixedly installed on the outside of the conductive rod 19, and a conductive brush 22 is fixedly provided on one side of the connecting block 21. External high voltage electricity is transmitted to the conductive rod 19 through the connector 20, so that the conductive brush 22 conducts electricity into the embossing roller 14.

[0036] like Figure 5 As shown, the connecting block 21 and the conductive brush 22 are integrated, and the connecting blocks 21 are evenly spaced on the conductive rod 19. The conductive brush 22 is in contact with the embossing roller 14. By setting multiple groups of conductive brushes 22, the conductive effect on the embossing roller 14 is improved, and the effect of electrostatic ink absorption is improved.

[0037] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and then according to the thickness of the paper, the handle 12 on the outside of the bracket 1 is rotated to drive the second gear 11 to mesh with the first gear 10 for transmission, and the first gear 10 is rotated to drive the screw rod 9 to rotate at the same time, and the movable frame 8 and the embossing roller 14 are adjusted in height in the bracket 1. After the height is adjusted, the first drive motor 3 and the second drive motor 13 are turned on to drive the printing roller 4 and the embossing roller 14 to rotate in opposite directions, and the lower part of the printing roller 4 is immersed in the ink tank 2 for inking, and then the paper is passed through the first group of static eliminators 5 to eliminate static electricity on the paper first, and then the paper enters the printing tank 2. In the brush roller 4 and the embossing roller 14, the electric field generated by the external high voltage electricity is introduced into the conductive rod 19 and the conductive brush 22 through the connector 20, and then the electricity is introduced into the embossing roller 14 through the conductive brush 22. The embossing roller 14 is a conductive rubber roller. Then the embossing roller 14 isolates the paper and absorbs all the ink in the printing roller 4, so that the paper forms static ink absorption. The printed paper is again destaticized by the second group of static eliminators 5. Finally, when the device is not used, the first drive motor 3 and the first drive motor 3 switch are turned off, and the external power supply is cut off. In this way, the use process of the printing machine with an electrostatic ink absorption mechanism is completed.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
