The electrostatic roller is provided with the dust removal device, the brush brushes off dust on the surface of the roller body when the electrostatic roller rotates, the two turbine air drums are used for continuously sucking the dust into the dust absorption chamber, and the electrostatic rod is used for adsorbing the dust, so that the dust on the surface of the electrostatic roller is removed at any time, the dust removal efficiency of the water printer is improved, and the working efficiency is improved. And when the dust on the electrostatic rod is too much, the alarm lamp flickers to remind people to clean the electrostatic rod and keep the dust removal efficiency of the dust removal device. Secondly, the hot air blown out by the drying device in the existing water printer is usually directly released into the air, and cannot be effectively reused. According to the invention, the exhaust box is additionally arranged on the right side of the drying device, the exhaust box collects the used hot air and sends the hot air to the air outlet cylinder through the air supply pipe, the hot air can blow part of dust on the paper board to the opposite absorption device, the dust is pre-removed in one step before the dust removal work of the electrostatic roller and the dust removal device, and the dust falling from the gap between the dust removal device and the electrostatic roller can be adsorbed, so that the environment-friendly and energy-saving effects are achieved, and the dust removal effect of the watermark machine is improved. Finally, the existing watermark machine is not provided with a dust hood, and dust can fall on a paper board after dust removal, so that the printing is damaged. The dustproof cover is arranged between the watermark roller and the electrostatic roller, and is pulled out from the fixed frame during use, so that the dustproof cover is convenient to use, and dust is prevented from falling on the paperboard after dust removal.
