Cutting paper size requirements of the crop askew, a knife incision pattern and there is even a knife, cut paper again and again, long after the next and so on are short is a common crop quality, with the exception of technical operations as a result of unskilled, collision Mixed paper, paper deformation, the paper again and again with the push of the relative position of the paper are not allowed, the paper folds inequality factors, other major factors are as follows:

1. Cutter factors

(1) Push on paper cut-size paper, the baseline was blocked after regulation, which should be parallel with the cut line, and vertical platform.

(2) When the whereabouts of the blade to blade with a vertical table, the edge of the blade should be parallel to the table and adjust to a certain height.

(3) Pressure paper should be able to cut in accordance with the requirements, adjust the size of the pressure and maintain its stability, the general gauge should be 4 ~ 10MPa, does not allow more than 15MPa, which is to ensure quality of crop.

As a result, installation and commissioning Cutter should be more accurate to adjust positions, or else will result in cutting the specifications do not meet the requirements or cutting askew.

 

2. Blade knife and regulation be inappropriate

There will be no whereabouts of the blade in place, even have a knife phenomenon; the whereabouts of the blade height is too low, so that the blade of the knife marks too, do not form a smooth incision or bursting knife, blade of the knife into the normal depth of 0.5 ~ 1mm; and blunt knife blade change formation does not even have a knife is also easy to cut or not, and so is bright and clean.

3. A small gap blade, cutting-edge of the knife appeared to spend.

4. Paper cut again and again, long after the next short period of the reasons

(1) Blunt edge of the blade, easy to cut out the surface layer by different specifications.

(2) Blade platform and not vertical.

(3) Push paper with the table surface before the surface is not vertical, paper-pushing forward, after cutting the paper again and again on the next long-short; push paper after the dumping, after cutting short paper stacked on the next long.

(4) The higher of the paper again and again, the pressure of the pressure on the paper corresponding increase, the paper again and again against the greater Cutter, which increases the bending deformation of the paper again and again, after cutting the paper appeared again and again on the next long-short phenomenon. Therefore paper should be a high degree of control again and again in the following 100mm; the thickness of the paper, the cutting height should be adjusted appropriately.

(5) Press the paper with the pressure should be cut by the nature of the paper. In order to ensure accurate cutting, standard size and number of changes, pressure must be pressed on paper to paper. General cut paper, paper pressure of the pressure should be greater; hard cut paper or cardboard, paper pressure of the pressure should be smaller.
