Corrugated Line Carton Upper and Lower Saw Slotter Knife Slotting Blade

Product Description

Slotter Knife

This fan-shaped knife, also known as a slottor knife, is mainly used for slotting on materials such as cardboard boxes and tissues. Fan shaped knives come in two types: toothed and toothless, which can easily create one or more grooves on corrugated cardboard.

Application of Slotter Knife

In the corrugated cardboard industry, slotting is an essential step in the production process of cardboard boxes. Therefore, slotting knives have a wide range of applications in this industry. After slotting with a fan-shaped knife, there will be indentations on the cardboard, which are used to accurately bend the corrugated cardboard according to the predetermined position, thereby achieving the internal dimensions of the cardboard box.

Material of Slotter Knife

The design of the slotter blade combines the excellent performance of high-speed steel with the unique advantages of a semi-circular structure, making it an important tool in the cardboard processing industry.

High speed steel, as an alloy tool steel with high hardness, high wear resistance, and good toughness, is an ideal material for manufacturing slotter blades. It can maintain stable cutting performance in high-speed rotation and high temperature environments, effectively extending the service life of the blade, reducing replacement frequency, and thus reducing production costs.

The semi-circular design allows the blade to better fit the curved surface of the cardboard box during the cutting process, achieving a smooth and precise cutting effect, avoiding excessive damage to the board, and improving the overall quality of the cardboard box.

In terms of technical principles, the high-speed steel semi-circular slotter blade of the cardboard printing machine comes into contact with the cardboard board through high-speed rotation, and uses the sharp edge of the blade to cut the board. During this process, factors such as the material, hardness, wear resistance, and cutting angle of the blade will directly affect the cutting effect. Therefore, high-quality slotted blades need to have characteristics such as high hardness, high wear resistance, good toughness, and precise cutting angles.
