There are so many different brands of machines for cutting corrugated paper. Different machines need different sizes of tungsten carbide corrugated slitter blades. However, no matter which equipment you are using, you should follow the 5 tips below:

After the carbide corrugated slitter blade is fixed, the knife edge cannot go left or right or jump up and down during operation.

Knife sharpening can be set manually or automatically. The material of the grinding wheel must match with the corresponding corrugated slitting blade to achieve effective sharpening.

Because corrugated cardboard still has a certain temperature when transferred to a slitting machine, the friction with cardboard causes the tungsten carbide corrugated slitter blade edge to heat up. When the temperature rises to a certain level, the sharpness of the knife-edge is affected. The cut edge of corrugated cardboard is very unsightly. Equipped with a cooling device can effectively improve the unsightly phenomenon of the cut edge.

Slitting blades must be embedded in the middle gap of the base cutting board to cut the cardboard. Under normal circumstances, the cutting edge shouldn’t embed in the gap for more than 10 mm depth.

Glue sticking to the knife will increase the thickness of the knife, and the cardboard will be subject to irregular friction, which will cause low productivity and affect lifespan. The following points you can do to prevent the phenomenon:
1) Appropriately reduce the amount of glue on the corrugated paper productionmachine.
2) Check whether glue is applied to the corrugated peak.
3) Check whether the glue area and glue line are too large.
4) Appropriately reducethe running speed ofcardboard, so that glue can be completely solidified.
