Technical Field

[0001] The present application relates to the technical field of printing cleaning equipment, and in particular to a printing rubber blanket cleaning device. Background Art

[0002] In the development of printing, a large amount of paper, ink and various materials are used. In order to promote environmental protection, the printing industry advocates green printing, which produces less pollution in the printing process, saves resources and energy, and is easy to recycle and reuse printed products after they are discarded, and is naturally degradable and has little impact on the ecological environment.

[0003] The inventors have discovered that this technology has at least the following problems. Environmental protection requirements need to be met during the printing process. The rubber cloth covering the transfer roller on the offset printing machine will become very dirty during the long-term process of transferring ink from the printing plate to the substrate. From the perspective of saving materials, it needs to be cleaned regularly. The existing cleaning roller is fixed to the slide plate by means of an extension rod threaded connection. Each time the cleaning roller is replaced regularly, the extension rods on both sides need to be twisted to replace the cleaning roller, resulting in a long printing pause time and reducing the production efficiency of the printed product. Therefore, a printing rubber cloth cleaning device is proposed to solve the above-mentioned problems. Utility Model Content
