How Cross Cutting Spiral Knife Reduces Paper Scraps Buildup In Corrugated Cardboard Production

Sun Hong spiral knife, made of the carbide tipped material, is a high performance cutting tool. It is widely used in many fields such as papermaking, cardboard box manufacturing, and film slitting.

With its excellent wear resistance, high strength, and stable cutting performance, the cross cutting knife becomes an ideal choice among many industrial cutting tools.

How To Solve The Paper Scraps Buildup Problem During Spiral Knife Cutting

Cutting is a crucial step in the corrugated paper production process. 

The carbide tipped cross cutting spiral knife, with its high hardness, wear resistance, and precise cutting performance, best fits the requirements of corrugated paper making.

But in actual production phenomena, paper scraps adhering to the cross cutting knife surface during the cutting process will affect the appearance quality of the product, and can also cause equipment blockage and reduce production efficiency. This problem has become a headache for many carton manufacturers.

Adjust Cutting Parameters

The cutting parameters of the spiral knife, including cutting speed, pressure, and angle, have a direct impact on paper scrap adhesion.

During the corrugated cardboard box cutting process, excessively high cutting speeds may prevent paper scraps from being separated in time, while excessively low pressure may not completely cut the corrugated paper, leaving sticky paper scraps.

Therefore, you need to adjust the cutting parameters of the spiral knife according to the material, thickness, and hardness of the corrugated paper to achieve the best cutting effect.

Use a Special Lubricant

Using a specialized cross cutting spiral knife lubricant during the cutting process can effectively reduce friction between paper scraps and lower the risk of paper scraps sticking together.

The choice of lubricant should be determined based on the material and the cutting conditions of the corrugated paper and the spiral knife.

Some high-performance lubricants can both lubricate and form a protective film during the cutting process, preventing direct contact between paper scraps and the spiral knives and helping reduce paper scrap adhesion.

Keep the Sharpness of the Spiral Knife

The sharpness of the spiral knife has a significant impact on the cutting effect and the adhesion of paper scraps.

The dull spiral knife will increase cutting resistance during paper cutting, causing paper scraps to stick together and damage the corrugated paper structure, affecting product quality.

Therefore, regularly inspecting and sharpening the spiral knife to keep it sharp is key to preventing paper scraps from sticking together.

Optimize the Cutting Environment

The cutting environment of the spiral knife, including temperature, humidity, and air circulation, will affect the adhesion of paper scraps during the cutting process.

For example, in environments with high temperature and high humidity, paper scraps are more likely to absorb moisture and stick together.

Therefore, maintaining a suitable temperature and humidity in the spiral knife cutting area, as well as good air circulation, helps reduce the adhesion of paper scraps.

Meanwhile, keeping the cutting area clean is essential to minimize the impact of dust and debris on the cutting performance of the cross cutting spiral knife.
