[0002] Printing paper is paper used for printing. Its main characteristics are flatness, smoothness, high whiteness and good ink absorbency. Printing paper is generally stored after being rolled up. It will become uneven during use, affecting the printing quality. Printing paper needs a transmission mechanism to feed it during printing. The transmission mechanism transmits the printing paper at a uniform and efficient speed. The printing paper is prone to looseness during the transmission process, which not only affects the smooth transmission of the printing paper, but also affects the subsequent flattening work. Wrinkles are prone to appear during flattening, and many transmission mechanisms now do not have the flattening function, which affects the printing quality. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case. Utility Model Content
