Green printing uses a printing roller structure for printing operations, so a printing roller for green printing is needed.

[0003] The existing printing roller for green printing has a surface that is in direct contact with the surface of the receiving object, which causes a large amount of heat to accumulate on the surface of the printing roller. The dye penetrates into the rubber of the outer wall of the printing roller, causing glazing of the rubber surface of the outer wall of the printing roller. Therefore, the printing roller needs to be cooled. The cooling structure of most printing rollers currently used dissipates heat through passive heat dissipation or increased air circulation. This heat dissipation measure is inefficient, and the rapid flow of air can easily affect the printed body and ink, so it is inconvenient when used.

[0004] For this reason, a printing roller cooling structure for green printing is proposed. Utility Model Content
