Background
Printers, machines for printing text and images. Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate. The invention and the development of the printing machine play an important role in the propagation of human civilization and culture.
In the existing printing machine, before or after the paper is printed by the printing machine, the paper is not too flat and is easy to wrinkle and turn over (such as printing heat and the inertia of roll paper); often resulting in the printer printing a printed image on a wrinkled sheet of paper or requiring manual finishing after printing (e.g., the printed matter cannot be arranged in the proper order due to the burring of the paper). Therefore, some printers have a platen mechanism for smoothing the paper.
