Technical Field

[0001] The utility model relates to the technical field of paper towel printing machines, in particular to a paper towel printing machine which is convenient for adjusting a flower roller. Background Art

[0002] Paper towels have good softness, absorbency and cleanliness. They are usually made of cotton pulp, wood pulp or straw pulp soaked in alkali or various disinfectants and then heated at high temperature before undergoing various fine processing. The surface of the product is wrinkled and mostly white. Some high-end paper towels also need to be embossed.

[0003] Among them, in order to make the multi-layer paper more adhesive during embossing, a small amount of glue will be brushed on the rubber roller. The rubber roller and the embossing roller are used together to emboss the surface of the base paper by vigorously squeezing it. In the common printing machine assembly, the embossing roller is located directly below the rubber roller, and the base paper on the rear frame can only be inserted into the gap between the embossing roller and the rubber roller in the horizontal direction.
