  Brief analysis of three slitting machines in slitting mode

    Flat knife slitting
  Like a razor, a single blade or double blade is attached to a fixed knife holder, and the knife is dropped during the material operation to allow the knife to cut the material lengthwise in order to achieve the goal of slitting.
  There are two ways to cut a razor:
  One is cutting monks, and the other is separation.
  Cutting is a material, running in the knife monk roll, will cut the knife in the monk monk roller, the material longitudinal cut, at this time, the material in the knife monk roll has a certain package angle, not easy to drift phenomenon. Then cut the casting PP film or film material is narrow, the common cutting method, can improve the cutting efficiency. But for suspending slitting, its disadvantage is that tool setting is inconvenient.
  After cutting material is suspended between two rollers, razor down material lengthwise, if the material is in a relatively stable state, so the cutting precision die cut Qielve is poor, but the cutting tool way is convenient, easy to operate. Flat knife slitting is mainly suitable for cutting thin plastic film and composite film.
  Circular cutter slitting
  Slitting can be divided into tangential cutting and non tangential slitting.
  The tangent is cut into material and cut from the tangential direction of the upper and lower two disc cutters. The cutter is more convenient, and the upper disc cutter and the lower disc cutter can be adjusted directly according to the cutting width requirement. Its drawback is that the material is easy to drift at the cutting point, so the accuracy is not high, and now generally do not use.
  Non slitting is the material and the lower plate has a certain angle, the lower disc knife, cut the material. The slitting method can make the material not easy to drift and has high cutting accuracy. But it is not very convenient to adjust the knife. When the disc knife is installed, the whole shaft must be removed. Round knife slitting is suitable for slitting and thicker composite film and paper.
  Extrusion slitting
  Extrusion cutting in cutting machine is not common, it is mainly by the synchronization with the speed and material and material have certain angle bottom roller and regulating gas knife easily formed. The slitting method can be used to cut thin plastic films, or to cut thick paper or non-woven fabrics. Is a relatively convenient way to cut. It is a development direction of slitting machine.
