The staff can regularly replace the paper cutter to maintain a good paper cutting effect of the paper cutting device."

[0004] According to the above-mentioned related technologies, the inventors believe that the above-mentioned technologies lack a pressing mechanism for printed materials. In the actual cutting process, the material is cut by squeezing from top to bottom. When some softer materials are cut, the positions at both ends that are not subject to force bulge upward due to pressure, which will pull the material to move slightly toward the cutting knife. This results in a small positive error between the material after cutting and the actual required size, and this error will increase with the increase of the cutting area, affecting the dimensional accuracy of the product.
