Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing equipment, in particular to an offset printing device. Background Art
[0002] Offset printing is a type of lithography. Simply put, offset printing is a printing method that uses a rubber sheet (rubber cloth) to transfer the image and text on the printing plate to the substrate. It is also the existence of the rubber cloth that gives this printing method its name. In the prior art, in order to ensure that all the dirt on the surface of the rubber roller can fall into the collection box during the cleaning process and not cause pollution to the surrounding environment, this requires that the size of the collection box used to receive the dirt dropped during the cleaning process of the rubber roller be much larger than the size of the rubber roller. In this way, it is more laborious and inconvenient for the operator to take the collection box or dump the dirt in the collection box.
[0003] After searching, Chinese patent publication (announcement) No. CN219903793U discloses an offset printing device, which adopts a cleaning piece that can move along the axis of the rubber roller and fits with the rubber roller, and a dirt collection box is set under the rubber roller, and the length of the dirt collection box is less than the axial length of the rubber roller, and the width of the dirt collection box is greater than the diameter of the rubber roller. By reducing the size of the dirt collection box, the operator can take it. Although the above patent solves the problem that the operator has difficulty in taking the collection box or dumping the dirt in the collection box, it cannot adjust the stamping pressure according to the thickness and characteristics of different printing materials, which is more likely to cause deformation and distortion of the printed matter, so it is necessary to add an adjustment device to adjust the stamping pressure according to the thickness and characteristics of different printing materials to a certain extent to ensure the printing effect and quality, and it is impossible to adjust and evenly distribute the ink. It is necessary to add a uniform device to absorb excess ink to a certain extent and then release it evenly to the rubber roller, which helps to keep the ink on the surface of the rubber roller evenly distributed and avoid the phenomenon of uneven ink on the printed matter. Therefore, it is necessary to design an offset printing device. Utility Model Content
