The slip shaft is usually a concept that is only involved in the slitter. It refers to a shaft with a large winding diameter and a small winding diameter that can be wound. The reason why the slitting machine needs to set the slip shaft is to use the principle of slipping on each slip ring on the slip shaft, so that the multiple reel materials on the shaft always maintain a constant tension for unwinding and unwinding.
If it is only a general winding shaft on the slitting machine, various materials can indeed be wound on one or two shafts uniformly, regularly and with constant tension from the core to the outer layer after slitting. However, because of the uneven thickness of the data itself, there is a certain thickness error, so a larger stacking error will occur after continuous winding.
However, the slip shaft is different. Its special structure is composed of multiple slip rings, which can effectively overcome the above problems. When the slitting machine is operating, the slip ring is controlled to slip with a certain slip torque value. At this time, the slip amount just compensates for the speed difference that occurs and then accurately controls the tension of each roll of data to achieve constant tension winding and ensure Coiling quality.
Because the tension control accuracy of the winding shaft in the slitting machine directly determines the elongation of the product and the regularity of the end face, it is necessary to use the slip shaft. Its effect is to improve the speed, winding accuracy, and automation of the slitting machine. , Reduce preparation time together and complete more user-friendly operations.
Because when the slitting machine is processing some thin polyester materials with poor tensile resistance and large thickness errors, it is necessary to use slip shafts, which can reduce the difficulty of rewinding, and together Reduce production costs to a certain extent.
