First, with the improvement of people's living standards and the development of science and technology, there is an increasing demand for flexible packaging products. The elongation requirements of the film are getting smaller and smaller, and the uniformity of the winding surface is getting higher and higher. Extremely high demands are placed on the tension control of the material film. The tension control accuracy of the take-up reel 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 take-up reel;
Secondly, after using the slip shaft, the automation degree, humanized operation, speed and winding accuracy of the slitting machine can be improved;
Third, the use of the slip shaft to take up valuable materials (metal foil, battery separator, special paper, etc.) can greatly improve the quality rate and reduce the cost; using the slip shaft, the difficulty of slitting and winding is reduced.
