Slitting machine is a kind of mechanical equipment for cutting wide-width paper, mica tape plastic film, adhesive tape, copper foil and aluminum foil into multiple narrow-width materials. It is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitting machine is mainly used for slitting of non-woven fabrics, mica tapes, paper, insulating materials and various film materials, especially suitable for the slitting of narrow tapes (non-woven fabrics, paper, insulating materials, mica tapes, films, etc.). cut.
It is a device that divides the whole web into multiple rolls, which requires that the tension of the internal winding shaft can be accurately controlled in sections, and only in this way can the elongation rate and end face uniformity of the product be guaranteed. However, due to the thickness error of the material itself, during the slitting coiling process, the diameter of each coil produces a large accumulation error, resulting in a large gap in speed and tension, uneven coil tightness, uneven end faces, and some coils due to tension. Too large and stretched.
Therefore, a rewinding shaft that can overcome these problems is needed to deal with it, and the slip shaft can just overcome these phenomena. The slip ring can slip with a certain slip torque, and the slip amount can just compensate for the speed difference, while Can accurately control the tension of each roll of material. According to the material, slitting width, thickness, and tension level, the ideal effect can be achieved by selecting the appropriate slip shaft.
So what is a slip shaft?
The slip shaft, also known as the differential shaft and the friction shaft, is used as the rewinding shaft and special unwinding shaft of the slitting machine. The slip shaft consists of a shaft core and multiple sets of slip rings, each slip ring slips independently, and the torque is controlled by the central air pressure or the pressure transmitted from the side. So as to ensure that each coil is uniformly and neatly wound with constant tension from the inside to the outside.
Why does the slitting machine use the slip shaft as the take-up shaft?
First, with the improvement of people's living standards and the development of science and technology, higher and higher requirements have been put forward for flexible packaging products. Extremely high demands are placed on the tension control of the material film. The tension control accuracy of the winding shaft directly determines the elongation of the slitting product and the uniformity of the end face, so it is necessary to use the slip shaft as the winding shaft;
Second, after using the slip shaft, the automation, humanized operation, speed and winding accuracy of the slitting machine can be improved;
Third, the use of slip shafts to coil valuable materials (metal foils, battery separators, special papers, etc.) can greatly improve the rate of genuine products and reduce costs; the use of slip shafts reduces the difficulty of slitting and winding.
