[0002] In the printing industry, printing rubber rollers, as key printing components, play a vital role in printing quality and efficiency. Printing rubber rollers are generally composed of metal shafts and rubber sleeve rollers, which can evenly transfer ink from ink cartridges or ink fountains to the printing plate, ensuring that the printed products have clear lines and bright colors.

[0003] Most of the existing printing rubber rollers are fixed structures and cannot be flexibly adjusted according to different requirements in the printing process. When facing printing materials of different materials and thicknesses, it is difficult to achieve the best printing effect with such fixed printing rubber rollers. In addition, the rubber rollers are easily contaminated with dust and stains after working for a long time and need to be cleaned in time to avoid affecting the printing quality. Therefore, there is a large room for improvement.
