Slitting MachineIt is a mechanical device that cuts wide paper, mica tape, or film into various narrow materials. It is commonly used in papermaking machinery, wire and cable mica tape, as well as printing and packaging machinery. The slitting machine is mainly used for: non-woven fabric; cutting mica tape, paper, insulating materials, and various film materials, especially suitable for cutting narrow strips (non-woven fabric, paper, thermal insulation materials, mica tape, film, etc.).
The cutting methods of the slitting machine mainly include three types: flat knife longitudinal cutting, circular knife longitudinal cutting, and groove longitudinal cutting. Each of these slitting methods has its own characteristics. Today, the manufacturer of Zhongchuang slitting machines will take us to understand the grooving and slitting methods of slitting machines.
Regarding the grooving method of the slitting machine, the principle is that when the material runs in the grooved roller, the knife falls into the groove of the roller, and the material is cut longitudinally. At this time, the material has a certain wrapping angle inside the grooving roller, making it less likely to drift. However, grooving and slitting are common methods for cutting cast polypropylene film or narrow edge film, which can improve slitting efficiency. Cutting machines rarely use grooving and cutting methods, usually employing the first two methods.
In addition to the three cutting methods mentioned above, there is actually another extrusion cutting method, but extrusion cutting is not commonly seen in domestic slitting machines. However, since this cutting method can cut not only thin plastic films but also thick paper, non-woven fabrics, etc., it is a relatively convenient cutting method and thus represents a development direction for slitting machine cutting methods.
