technical field [0001] The invention relates to the technical field of printing, in particular to an advertisement printing device. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. [0003] During the advertising printing process, the side of the printing roller is in contact with the paper, and other parts of the side of the printing roller are immersed in the ink tank. When the printing roller rotates, the side of the printing roller is dipped into the ink and contacts the paper with the rotation of the printing roller , thereby applying the ink to the paper. But, because the printing roller rotates faster, when the printing roller rotates at a high speed, the printing roller and the ink in the ink tank collide with each other, thereby easily causing the ink ...
