Cross-cutting machine belongs to the carton processing machinery. The cross cutting machine in the corrugated cardboard production line is a mechanical device for cutting cardboard products, and its technical performance and equipment adjustments directly affect the cutting size of the finished cardboard, whether or not the pressure line is broken and whether or not the appearance of the incision is smooth and beautiful. Cross cutting machine blade is used in cross cutting machine, about cross cutting machine is one of the important single machine of cardboard production line. Cross cutting machine due to different transmission control mode, divided into mechanical cross cutting machine.

Cross cutting machine blade picture machine and computer control cross cutting machine. Computerized cross cutting machine is controlled by industrial control computer, according to the set length, control the knife shaft operation cut off cardboard, coupled with the mechanical part of the precision transmission, can be cut paper error control in the range of ± 1mm. Computer-controlled cross-cutting machine has a spiral knife cross-cutting machine, straight knife cross-cutting machine. Spiral knife cross-cutting machine is more suitable for high-speed cutting thick cardboard, and cut paper smoothly, long blade life, the blade should use high-speed steel material.

Cutting machine blade currently there are two kinds of domestic, overall cross-cutting knife, inlaid cross-cutting knife.

The whole cross-cutting knife is the use of SKD11, CR12, 9CRSI and other materials whacking molding, heat treatment and grinding out the knife, HRC50-58 degrees, the material is not the same as the hardness of the same, the general service life of this blade is not high, the knife is not sharp enough to cut some high-precision material effect is not good.

Inlaid cross-cutting knife refers to the knife mouth inlaid high-speed steel HSS, knife body using abrasive steel SKD11, heat treatment grinding out the use of the knife mouth, HRC60-63 degrees, different high-speed steel HRC is not the same, the general service life of this blade is high, we all know that high-speed steel hardness high toughness, suitable for high-speed cutting, even if the cutting of some of the high-precision materials are easy to use, the cutter is smooth and smooth burr-free, long-lasting durability. The cutting edge is flat and smooth without burrs, long lasting.
