As we all know, the overall smoothness of the ivory board is an important factor in determining the quality of the paper. Smoothness covers the roughness of the front and back sides and the smoothness of the edges.
The smoothness of the front and back sides of the paper will directly affect the printing effect, And if the edge of the paper has a rough edge, there will be many small debris in the printing process, resulting in an unsatisfactory printing effect.
What determines the smoothness of the paper's edges?
The deciding factor is the blade of the paper cutter. Whether the blade is sharp or worn excessively?
But there is one problem that the blade can't solve. When the ordinary single knife cutter cuts the paper, the paper will be squeezed into the indentation mold, which will produce tension in the paper. When the blade cuts into the bottom of the paper, the instant tension will tear off the remaining part of the back, so the burr appears.
The cutting mode of double knife paper cutter can solve this problem completely.
A slitting knife roller is arranged at the horizontal position between the front end of the longitudinal cutting knife silver on the head of the photoelectric cutting machine and the vertical cutting knife roller. The middle part of the slitting roller is provided with a slitting longitudinal paper cutter, which is staggered with the middle longitudinal paper cutter of the slitting knife.
The middle longitudinal paper cutter and slitting longitudinal paper cutter are equally distant from the end longitudinal paper cutter at both ends.
The advantage of the double-knife paper cutter is that when the paper enters the machine, such as NINGBO FOLD C1S Folding Box Board ,it is simultaneously cut through the end, middle and four longitudinal paper cutter, and the burr edge of the paper is removed. One slitter completion, improve the precision of paper cutting, improve product quality, reduce the rate of defective products,reduce production costs.
