Slitter Blade is an important component on slitter equipment. It is mainly used to cut large coils into small coils of different specifications according to process requirements. Improper selection of the slitter blade, if it is not selected according to the mechanical configuration, the slitting index product requirements will not be met, the slitting material will cause burrs and a large amount of slitting dust. Not only will it reduce the accuracy and speed of slitting, but it will also consume raw materials. It is also easy to cause the shortening of the life of the cutting blade, which increases the production cost. So how to choose the right cutter blade? Slitting Blade Manufacturer will tell you the trick next.
 

Slitter Blade
 

1. There are two main methods for cutting circular cutters: upper and lower disc cutters and circular cutters. Circular knife slitting is the main slitting method for slitting thick film, composite thick film, paper and other materials. Cutting material The thickness of the film is more than 100um.
 

2, the upper and lower disc slitting blade methods are widely used, mainly tangential slitting and non-tangential slitting. The tangent cutting is the material cutting from the tangential direction of the upper and lower disc cutters. This kind of slitting is more convenient. The upper disc cutter and the lower disc cutter can be adjusted according to the requirements of the cutting width. Its disadvantage is that the material is prone to drift at the slit, so the accuracy is not high, and it is generally not used now. Non-tangent cutting is that the material has a certain angle with the lower disc knife. The lower disc knife falls and cuts the material. This cutting method can make the material less likely to drift, and the cutting accuracy is high. However, it is not convenient to adjust the knife. When the lower disc knife is installed, the entire shaft must be removed. Round knife slitting is suitable for slitting thicker composite film and paper.
 

3. The application of circular knife extrusion slitting in the industry is not common. It is mainly composed of synchronized with the speed of the material and a certain angle with the material, the bottom roller and the convenient pneumatic slitting knife. This slitting method can not only slit thinner plastic films, but also slit thicker paper and non-woven fabrics. It is a more convenient cutting method, and it is also a development direction of the cutting machine.
 

4. When selecting the blade of the slitter, it must be suitable for the blade of the machine. Some users always one-sidedly and objectively pursue imported blades, but ignore the blades that should be matched with their own models. Without distinguishing the application of the blade and its own purpose, it is considered that only imported blades are good and durable blades. In fact, whether it is imported or domestic, it is only suitable for the product application, is the appropriate blade.
 

5. The advantages and disadvantages of the slitter blades are relative. The key to the cutting effect of the blades lies in the application. For example, improper application of imported blades will not have good results, and domestic blades will also have good results if they are properly applied.
