Problems solved by technology

[0002] During the printing process of the printing machine, in order to print uniformly, the color is the same before and after, there is no great difference in viscosity and good fluidity, use a clean wooden or metal rod to stir the ink in the ink tank evenly, but in the transmission When the ink roller transfers ink to the printing plate cylinder, it is necessary to scrape the printing plate cylinder. If the scraper is not fixed properly, it is easy to shift up and down, resulting in inconsistent horizontal and left heights, and the scraping pressure is different. The printing plate cylinder The ink distribution is uneven, resulting in the printed finished product, the ink distribution is uneven, some places are very light, some places are very deep, and the quality is poor

Abstract

The invention discloses a printing machine doctor blade system with a leveling function. The structure of the doctor blade system comprises a doctor blade structure, an ink tank, an ink transfer roller, a printing plate cylinder and an impression cylinder, wherein the ink tank is provided with the ink transfer roller, the ink transfer roller is positioned obliquely below the printing plate cylinder, the printing plate cylinder and the ink transfer roller are movably attached to each other, one side of the ink transfer roller is provided with the doctor blade structure, the impression cylinderis arranged in the middle of the top end, opposite to the ink tank, of the printing plate cylinder, and the impression cylinder and the printing plate cylinder are closely attached to each other. According to the doctor blade system, whether a doctor blade is placed horizontally or not is calibrated through a blade placing platform, so that the blade body, tangent to the printing plate cylinder, of the doctor blade is further ensured to be in the same horizontal line without deflection, and the doctor blade can scrape the printing plate cylinder uniformly; and according to the doctor blade, three thread knobs are fixed on the blade placing platform uniformly and equidistantly, when the doctor blade is installed, three points are stressed uniformly, so that the adhesion degree between the doctor blade placing platform and the doctor blade is further guaranteed, and the influence on the distribution of the doctor blade caused by local lifting or the gap of the doctor blade is avoided.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a doctor blade system of a printing machine with a leveling function. Background technique [0002] During the printing process of the printing machine, in order to print uniformly, the color is the same before and after, there is no great difference in viscosity and good fluidity, use a clean wooden or metal rod to stir the ink in the ink tank evenly, but in the transmission When the ink roller transfers ink to the printing plate cylinder, it is necessary to scrape the printing plate cylinder. If the scraper is not fixed properly, it is easy to shift up and down, resulting in inconsistent horizontal and left heights, and the scraping pressure is different. The printing plate cylinder The uneven distribution of the ink, resulting in the printed finished product, the ink distribution is uneven, some places are very shallow, some places are very deep, and the quality is poor. Co...
