Description

Technical Field

[0001] The utility model belongs to the technical field of printing plate rollers, in particular to a detachable printing plate roller. Background Art

[0002] The working principle of a printing press is: first, the text and images to be printed are made into a printing plate and installed on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. The printing plate roller and the impression roller need to be used together during the printing process.

[0003] The existing technology has the following shortcomings: the printing plate roller is mainly composed of a roller shaft and connecting shafts arranged at both ends of the roller shaft. The existing roller shaft and connecting shaft are an integrated structure. When the components of the printing plate roller with an integrated structure are damaged after long-term use, the entire printing plate roller needs to be replaced, which has a short service life, high component loss and high use cost. At the same time, the integrated printing plate roller cannot adjust the length of the printing plate roller according to different models, and the flexibility of use is insufficient and too limited.
