Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting and pushing devices, in particular to a cutting and pushing device of a printing press. Background Art
[0002] The printing press first makes the text and images to be printed into a printing plate, installs it on the printing press, and then applies ink to the places with text and images on the printing plate manually or by the printing press, and then directly or indirectly transfers it to paper or other substrates, thereby replicating the same printed product as the printing plate. There are many types of printing presses. When printing some papers with a certain thickness, multiple stacked paper grids are placed at the feed port of the printing press, and then the paper is fed. During the paper printing process, a paper cutter is needed to cut the stacked large-size paper. At present, the stacked paper is generally pushed along the operating table to the cutter of the paper cutter for cutting.
[0003] In the prior art, the stacked paper is manually placed on the cutting platform, and then a hydraulic rod pushes the push plate to push the paper stack into the cutting device. When pushing it in, the front and back can be trimmed, and then the hydraulic pressure plate is used to fix it, and then the excess corners are cut off with a cutting knife. However, the two sides of the paper stack are not trimmed during the trimming, so the paper stack is not neat. In view of the above problems, a method is designed to trim the two sides of the paper stack on the basis of the front and back trimming, so as to facilitate accurate cutting. Utility Model Content
