Atomizing diffusion roller 6 and electric heating printing roller 7 are respectively arranged between adjustment positioning plate 3. In the process of paper towel production, atomizing diffusion roller 6 spreads liquid such as additives, softener, etc. in the form of atomization evenly on the surface of paper towel through specific structure and working mode, thereby improving the performance of paper towel. When paper towel passes through electric heating printing roller 7, under the combined action of pressure and temperature, printed pattern is printed on the surface of paper towel, which not only gives paper towel beautiful appearance, but also can customize different patterns according to market demand to meet the diverse aesthetic needs of consumers.

Since the lifting threaded hole on the movable positioning plate 301 is threadedly connected with the adjusting electric screw 201, the movable positioning plate 301 will make a linear motion along the axial direction of the screw under the action of the rotation of the screw. At the same time, the connecting sliding hole is slidably engaged with the adjusting electric screw 201 to ensure that the movable positioning plate 301 slides smoothly.
