How To Choose The Right Slitting Blade
In the slitting machine equipment there is an important part - the slitter blade. Its role: mainly to slit large rolls of material according to the process requirements into different specifications of small circle material. If not selected according to the mechanical configuration, and the choice of improper slitter blade, will not meet the slitting index product requirements, slitting the material will produce burrs and produce a large number of slitting powder chips, etc.. Not only will reduce the precision and speed of slitting, consuming the product raw materials; also easy to cause slitting blade life shortened, increasing production costs.
Slitting circular knife introduction.
Slitting round knife mainly has the upper and lower disc knife shear and round knife extrusion type slitting two ways. Round knife slitting is slitting thick film, composite thick film, paper and other materials, the main slitting method. Slitting material film thickness of 100um or more recommended to use circular knife slitting.
Upper and lower disc slitting blade way widely used, mainly cut line slitting and non-cut line slitting two. Tangent line slitting for the material from the upper and lower two disc knife tangent line direction slitting, this kind of slitting on the knife is more convenient, the upper disc knife and lower disc knife can be according to the slitting width requirements, easy to place to adjust the position. Its disadvantage is that the material is easy to drift phenomenon at the slitting, so the accuracy is not high, now generally not used. Non-tangent line slitting is the material and the lower disc knife has a certain wrap angle, the lower disc knife falls down and cuts the material. This slitting method can make the material less likely to drift and the slitting accuracy is high. However, it is not convenient to adjust the knife, and the whole shaft will be removed when the lower circular knife is installed. Round knife slitting is suitable for slitting thicker laminated film and paper type. Round knife extrusion type slitting is not common in the industry applications, it is mainly composed of synchronized with the speed of the material and a certain wrap angle with the material, the bottom roller and easy to adjust the pneumatic slitting knife. This slitting method can slit both thin plastic films and thicker paper, non-woven fabrics, etc.. It is a more convenient slitting method, and is also a development direction of the slitting machine slitting method.
In the choice of slitter blade, must be suitable for the machine blade, can not always one-sided objective pursuit of imported blades, but ignored with their own models should be compatible with the blade. Therefore, regardless of whether it is imported or domestic, only distinguish between the application of the blade and their own use, choose the application of the product is conducive to the appropriate blade, and not simply think that only imported blades are good, durable blades.
