Sliding shaft is used for cutting and winding low tension products. The slip ring on the sliding shaft will be wound according to the different tension of each roll of material. The slip ring on each roll of material will slide with the shaft to achieve the effect of balancing and stabilizing tension. Finally, the end face of the wound product is neat and elastic, which solves the shortcomings of the inflatable shaft (irregular end face, some winding materials are loose and some are too tight). At the same time, the sliding bearing is very important, the maximum shaft can reach 60 and the minimum shaft can reach 50. Usually, for those with a load of more than 200 kg, I think it is necessary to properly assemble a receiving rack, which is convenient for workers to operate under the condition of protecting the sliding shaft from deformation, and one person can operate a slitting machine completely.
