How to choose the correct and suitable slitting machine blade

The slitting machine blade is an important component on the slitting machine equipment. Mainly, it is to divide large rolls into different sizes of small coils according to process requirements. Improper selection of slitting machine blades and failure to select according to mechanical configuration will result in failure to meet the slitting requirements of the product. The slitting material will produce burrs and a large amount of slitting powder chips. Not only will it reduce the accuracy and speed of cutting, but it will also consume raw materials for the product. It is also easy to shorten the service life of the slitting blade and increase production costs. Where and how to choose the one that is suitable for the machine Cutting machine blade? When choosing, pay attention to the following points:;

1There are two main methods for cutting circular knives: upper and lower disc knife cutting and circular knife extrusion cutting. Circular cutting is the main cutting method for cutting thick films, composite thick films, paper and other materials. The thickness of the cutting material film is100umThe above suggestion is to use a round knife for cutting.

2The upper and lower disc cutting blade methods are widely used, mainly including tangential cutting and non tangential cutting.

1)Tangent cutting is the process of cutting the material in the direction of the tangent line between the upper and lower disc cutters. This type of cutting is convenient for cutting, and the upper and lower disc cutters can be easily adjusted in position according to the cutting width requirements. Its disadvantage is that the material is prone to drift at the cutting point, so the accuracy is not high, and it is generally not used now.

2)Non tangential cutting is when the material and the lower disc knife have a certain angle of overlap, and the lower disc knife falls down to cut the material open. This cutting method can prevent material drift and achieve high cutting accuracy. But adjusting the knife is not very convenient, and when installing the lower disc knife, the entire shaft must be removed. Round knife cutting is suitable for cutting thick composite films and paper.

3The application field of round knife extrusion slitting is not very common in the industry. It is mainly composed of a pneumatic slitting knife that is synchronized with the material speed and has a certain wrapping angle with the material, a bottom roller, and easy adjustment. This cutting method can cut both thin plastic films and thick paper, non-woven fabrics, etc. It is a convenient cutting method and also a development direction of the cutting machine cutting method.

4When choosing a slitting machine blade, it is necessary to choose a blade that is suitable for the machine. Some users always pursue imported blades objectively, but ignore the blades that should be matched with their own model. Without distinguishing between the application of the blade and its own purpose, it is believed that only imported blades are the best and most durable blades. In fact, whether imported or domestically produced, only blades that are conducive to product application are the most suitable.

5The quality of slitting machine blades is relative, and the key to the cutting effect of the blades lies in their application. For example, improper application of imported blades will not have good results, while domestic blades can also have good effects if applied reasonably.
