Description
Technical Field
The invention relates to a printing cylinder mechanism of an offset press, and belongs to the technical field of offset presses.
Background
The offset press is applied on a large scale in China, and currently becomes the main stream of the printing industry in China, and the offset press transfers the printing text from a printing plate to a blanket cylinder and then transfers the printing text to paper by the blanket cylinder during printing, so that the printing effect can be obviously improved. The blanket cylinder acts as a transfer core and its operating state determines the final printing effect.
The surface of the blanket cylinder is wrapped with a layer of blanket, and in the using process of the blanket, the blanket is required to be cleaned and maintained frequently in order to prolong the service life of the blanket. When printing, especially when the quality of printing paper is poor, a layer of accumulation layer formed by paper surface particles, fibers and pigment particles in ink is easily formed on a surface adhesive layer of the blanket due to physical adsorption, so that the printing pressure applied to the blanket is increased and the damage is also larger. In addition, most of the accumulation layers are polar substances, so that local oleophilic and hydrophilic properties of the blanket are changed, local small dots on the printing plate are difficult to be displayed on paper through the blanket, the dot reduction effect is poor, the conditions of local pasting of printed matters, occurrence of powdery fine dots and the like are caused, the printing quality is seriously affected, and only reprinting is carried out if necessary. In order to prevent paper dust, ink, etc. from accumulating on the blanket, it is necessary to clean and maintain the blanket at regular intervals or in a certain number of prints (for example, about 5000 sheets) depending on the quality of paper, ink, etc. If the blanket is improperly maintained, the blanket may be scrapped within half a year of use, and if the blanket is properly maintained, the blanket may be used for even two years. In addition, if the blanket cylinder is not cleaned during color changing, the purity of new ink color is affected, so the blanket cylinder is cleaned during color changing.
During manual cleaning, the rubber blanket is generally wiped by a water wiping cloth, then the rubber blanket is wiped by a gasoline wiping cloth, finally the rubber blanket is wiped by a clean wiping cloth, and the manual cleaning is relatively troublesome and has low efficiency, has potential safety hazards, and can cause additional damage to the rubber blanket if the rubber blanket is not noticed. Thus, larger printing plants now prefer to use more efficient blanket automatic cleaning devices. But the automatic cleaning device is very expensive, the automatic cleaning cloth needs to be replaced when the automatic cleaning cloth is used up, and the automatic cleaning cloth on the automatic cleaning device is difficult to achieve a thorough cleaning effect on tiny impurity particles. When the automatic cleaning device is in practical application, the cleaning structure can continuously clean the roller as long as the offset press is started, when the roller is in use, the surface of the roller is liquefied due to higher surface working temperature, so that the roller is attached to the surface of the roller, patterns are very easy to form when the cleaning structure is in cleaning action, the roller cannot be completely cleaned, the roller is cleaned when in working, the cleaning structure can also influence the excellent performance of the roller, and color difference and even color mixing occur when the color is adopted.
