A4 paper crosscutting machine blade is an essential processing link in the processing and manufacturing of the paper industry. If there is a deviation in the blade of the crosscutting machine, the quality of the paper product production will be affected. Therefore, we need to analyze the common deviations of different paper products to reduce this potential risk.
A4 paper crosscutting machine blade deviation analysis
A4 paper crosscutting machine blade slitting cardboard tail deflection:
1. Improper adjustment of the paper feed positioning baffle of the cross-cutting machine blade;
2. The blade of the cross-cutting machine is too blunt, which is different from the linear speed of other knives;
3. The paper guide wheel of the cross-cutting machine blade is improperly adjusted;
4. The blade of the cross-cutting machine is improperly fed.
A4 paper crosscutting machine blade produces burrs:
1. The blade of the cross-cutting machine is dull and should be polished;
2. The overlap between the blade of the cross-cutting machine and the groove is too shallow;
3. The edge of the paper and the paper wool are caught in the slot of the blade of the cross-cutting machine, which should be thoroughly cleaned and then turned on;
4. The kerf clearance of the cross-cutting machine blade is too large, generally not more than 2.5mm.
A4 paper crosscutting machine blade indentation line is easy to break:
1. The base paper is inferior;
2. The pressure line is too deep.
The A4 paper crosscutting machine blade indentation line is not straight:
1. The pressure line of the cross-cutting machine blade is too shallow, and the folding line is uneven, which affects the appearance of the box;
2. The paper feed of the cross-cutting machine blade is skewed;
3. The upper and lower pressure rollers of the cross-cutting machine blade are not adjusted properly.
A4 paper crosscutting machine sheet cutting edges are not vertical:
1. The angle of the blade holder of the cross-cutting machine is incorrect;
2. The blade of the cross-cutting machine is not in the center of the groove;
3. The blade of the cross-cutting machine is sharpened.
