Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a single-side and double-side switching device of a printing press. Background Art

[0002] A printing press is a machine that prints text and images, typically consisting of a plate-mounting, inking, embossing, and paper feed mechanism. The principle is that the text and image to be printed are made into a printing plate, which is then mounted on the press. Ink is then applied to the plate where the text and image are located, either manually or by the printing machine. The ink is then directly or indirectly transferred to paper or other substrates. As a vital piece of equipment in the modern printing industry, the performance and functionality of a printing press are crucial for improving printing efficiency, reducing production costs, and ensuring print quality. During the printing process, the single-sided or double-sided switching device is a key component for achieving single-sided or double-sided printing.

[0003] The single-sided and double-sided switching devices of some printing machines require manual adjustment of the positions and states of multiple components, which not only increases the difficulty of operation, but may also lead to inaccurate adjustments and affect printing quality. At the same time, the single-sided and double-sided switching devices of some printing machines are prone to errors during the switching process, resulting in inaccurate paper positioning and inability to adapt to papers of different specifications and materials, limiting the application range of the printing machine.
