Paper making rubber rollers are mainly used for pressing, pressing, and calendering different parts of paper machines. What are the debugging methods for them? Here is the editor's summary:
After the new equipment is installed, regardless of the type or model of printing, technicians and leaders should first install the paper roller. Its installation and requirements are reasonable, as it needs to be in close contact with the ink roller and printing plate, both of which are indispensable. The printing staff all know that the height of the letterpress is 3.14 millimeters, which is consistent with the height of the lead type, while the PS version is relatively 1.2 millimeters lower, so it is important to have a clear understanding when installing and debugging the rubber rollers.
If it is printing with a base color, the paper roller can be lowered to an error of 0.5 millimeters. This way, the ink conveyed by the ink roller to the roller is relatively uniform, and the effect reflected by the printing roller on the printing plate is the same. The printed product is pleasing to the eye. Otherwise, phenomena such as ink streaks and knife sticking may occur.
When printing and writing, the height of the paper roller is basically equal to or slightly lower than the text plate. In this way, the printing roller can gently rub the printing plate, making the text printed very clear and neat. Moreover, the wear surface of the roller is small and not easily damaged, which can extend the service life of the printing plate. Adjust the rubber roller. Before use, remove the printing plate and let the rubber roller extend horizontally, pulling it out several times. The size of the ink dots on the rubber roller will be immediately displayed. The operator can determine the level of the printing roller according to different printing needs, and then fix the top thread.
The surface of paper rollers should be delicate, smooth, and slightly sticky, with good ink transfer performance. I hope the above content is helpful to you.
