There are also many slitting methods of slitting machines, each of which has its own advantages. The following is a brief introduction of the advantages and disadvantages of slitting methods.

        1. Round knife slitting

        Circular knife slitting can be divided into tangent slitting and non-tangent slitting.

        The tangent cutting is the data cutting from the tangential direction of the upper and lower disk knives. This kind of slitting is convenient for comparison. The upper disk knife and the lower disk knife can be directly adjusted according to the cutting width request. Its drawback is that the data is very simple, and the appearance of drift occurs at the slit, so the accuracy is not high, and it is usually not necessary today.

        Non-tangential cutting is that the data and the lower disc knife have a certain wrap angle. The lower disc knife falls and cuts the data. This cutting method can make the data less prone to drift, and the cutting accuracy is high. However, it is not very convenient to adjust the knife. When lowering the disc knife device, the entire shaft must be removed. Round knife slitting is suitable for slitting thicker composite films and paper.

        2. Flat knife slitting

        Just like a razor, a single-sided blade or a double-sided blade is fixed on a fixed knife holder, and the knife is dropped during the operation of the data, so that the knife cuts the material longitudinally to achieve the purpose of slitting.

        There are two methods for razor slitting:

        One is slitting and slitting; the other is dangling slitting.

        Grooving and slitting is when the data is running on the grooving roller, the cutter is dropped in the groove of the grooving roller, and the data is cut longitudinally. At this moment, the data has a certain wrap angle in the grooving roller, and it is not easy to have a drift appearance. When slitting cast PP film or film with narrow edge material, this kind of slitting method is often used to increase the slitting power. However, the shortcoming of dangling slitting is the inconvenience of knife comparison.

        Hanging slitting is when the data passes between the two rollers, the razor falls and cuts the data longitudinally. At this moment, the data is in a relatively unstable state, so the slitting accuracy is slightly worse than the die slitting, but this method of slitting Convenient tool setting and convenient operation.

        Flat cutter cutting is mainly suitable for cutting very thin plastic films and composite films.

        3. Extrusion slitting

        Extrusion slitting is rare in domestic slitting machines. It is mainly composed of a bottom roller with a speed that is synchronized with the data, a certain angle with the data, and a pneumatic knife that is convenient to adjust. This slitting method can slit both thin plastic films and thick papers, non-woven fabrics, etc. It is a convenient and convenient cutting method. It is a development direction of slitting method of slitting machine.

        After reading the above, I believe everyone already knows the advantages and disadvantages of the cutting method.
