The size of the paper cut to specification, whether the cut is clean and the height of the paper stack, the geometry of the cut and the sharpness of the grinding edge, the pressure of the paper stack, the type of paper and moisture content, the state of the paper cutter has a close relationship.
As the height of the paper stack increases, the error of cutting size increases. Because the paper stack is too high, the pressure of the paper press increased accordingly, the paper stack of anti-cutting force is large, thus increasing the bending deformation of the paper stack, cut out the paper will appear on the upper part of the stack of long lower short. Therefore, cutting the height of the paper stack is best controlled in the following 100mm is appropriate.
When using a double-grinding blade carrier knife, the friction and cutting force of the paper stack on the beveled surface of the carrier knife is reduced, and the accuracy of cutting is improved. Knife edge grinding sharp, cutting when the cut material on the knife's resistance to cutting force is small, the wear and tear of the machine and power consumption is small, the cut product neat, clean cut. Conversely, the grinding edge is not sharp, cutting quality and cutting speed will be reduced, cutting the paper stack is easy to pull out the paper above, the phenomenon of inconsistent upper and lower cutter.
The paper press must be pressed along the paper cutting line. As the pressure of the presser increases, the possibility of paper being pulled out from under the presser is small, the accuracy of cutting is high. The size of the pressure of the paper press should be adjusted according to the type of paper to be cut, the height of the cut, the sharpness of the grinding edge and other factors to adjust.
When cutting different types of paper, the pressure of the paper press and the angle of the grinding blade should be used to adapt to it. The correct pressure of the paper press should be able to cut the knife along a straight line into the paper stack. Generally speaking, when cutting soft and thin paper, the pressure of the paper press should be larger, if the pressure is small, the paper stack above the paper will produce bending deformation, the paper stack on the deformation of large, cut paper appears on the long under the short phenomenon; cut hard and smooth paper, the pressure of the paper press should be smaller, if the pressure is too large, in cutting the knife blade is easy to pressure on the small side of the deviation, cut paper appears on the short under the long phenomenon.
In cutting rigid paper, to overcome the cutting resistance, the cutting knife grinding angle should be larger. Otherwise, due to the thin grinding edge, can not overcome the paper's resistance to cutting force, the formation of the lower part of the paper stack cut insufficient and other phenomena, affecting the quality of cutting.
