Its characteristics are excellent printability and high opacity. During the paper printing production process, paper undergoes multiple steps from printing to binding. During the printing process, the paper needs to be transferred and transported multiple times, necessitating the use of a device to flatten the paper.

The utility model is provided with a threaded rod and a driving motor in the installation plate, and the driving motor drives the threaded rod to rotate, so that the second movable block on the threaded rod moves horizontally, which facilitates the pressing roller to press back and forth on the paper, thereby achieving a better flattening effect of the paper. At the same time, by placing the electric heating tube horizontally in the installation cavity of the workbench, the paper is dried while being flattened, which facilitates the transfer of images and texts to the paper during printing.
