How to choose the paper tube machine blade is based on the different varieties of slitting materials and thickness to the resolution . We first need to understand the classification and application of different blades usually paper tube machine blade slitting method contains square knife slitting and round knife slitting.
Square knife slitting is the same as razor, the blade fixed in the paper tube equipment on the knife frame, in the process of running the knife down, so that the knife will be cut longitudinally, in order to achieve the slitting intention.
Square paper tube machine blade is divided into single-sided blade and double-sided blade.
Single-sided blade on the thicker, more rigid slitting thick film is better, because in the case of paper tube machine at high speed hard blade is not simple displacement, to ensure product quality.
Double-sided blade is relatively soft, suitable for some thin material slitting, so that the film edge flatness is ensured, together with the ability to extend the service life.
Square knife slitting is usually divided into slotted slitting and overhanging slitting two kinds: slotted slitting is slitting machine running in the knife slot roller, the knife will fall in the slot of the knife slot roller, the data will be cut longitudinally, at this moment the data in the knife slot roller has a certain angle, it is not easy to attack the drift phenomenon. But on the overhang slitting, its defect is that the knife is more troublesome. Overhanging slitting is the material between the two rollers, the blade will fall to cut the material longitudinally, at this moment the material is in a relatively unstable condition, so the slitting accuracy is slightly worse than cutting die slitting, but this slitting method is convenient for the knife, the operation is convenient. Round knife slitting the primary upper and lower disc knife shear and circular knife kneading type slitting two methods. Up and down circular knife slitting method is widely used, paper tube machinery factory has cut line slitting and non-cut line slitting two. Cut line slitting for the material from the upper and lower two circular knife tangent line direction slitting. Non-tangent line slitting is the material and the lower disc knife has a certain angle, the lower disc knife down, the material will be cut. Circular knife kneading slitting is not very common in the field of professional use. It is mainly composed of the bottom roller which is synchronized with the material speed and has a certain wrap angle with the material and the pneumatic slitting knife which is easy to adjust.
