The slitting machine blade is an important processing link in the production of cardboard and carton. Therefore, if the slitting machine blade has deviations, it will affect the quality of cardboard and carton products, and even the products produced will be waste. Therefore, we need to analyze the common deviations of corrugated cardboard slitting machine blades to reduce waste in cardboard and carton production.
The tail of the slitting machine blade cutting cardboard is deflected:
1. The paper feeding positioning baffle of the slitting machine blade is improperly adjusted;
2. The slitting blade has a section that is too blunt and has a difference in linear speed with other knives;
3. The paper guide wheel of the slitting machine blade is improperly adjusted;
4. The slitting machine blade feeds paper improperly.
The slitting machine blade has burrs:
1. The slitting machine blade is blunt and should be polished;
2. The overlap between the slitting machine blade and the knife groove is too shallow;
3. The knife groove of the slitting machine blade is rolled into paper edges and paper hair, which should be cleaned before starting the machine;
4. The knife groove gap of the slitting machine blade is too large, generally not more than 2.5mm is appropriate. The indentation line of the slitting machine blade is easy to break:
1. The base paper is inferior;
2. The indentation line is too deep.
The indentation line of the slitting machine blade is not straight:
1. The indentation line of the slitting machine blade is too shallow, and the folding line is uneven, which affects the appearance of the box;
2. The paper feeding of the slitting machine blade is skewed;
3. The upper and lower indentation wheels of the slitting machine blade are not adjusted.
The incision edge of the slitting machine blade is not vertical:
1. The angle of the slitting machine blade holder is not correct;
2. The slitting machine blade is not in the center of the knife groove;
3. The blade of the slitting machine blade is ground eccentrically.
