Mechanical Differential Shaft

The differential shaft has a special structure and is composed of a plurality of slip rings, which can overcome the above phenomenon. During operation, the slip ring is controlled to slip with a certain slip torque value (torque), and the slip amount just compensates for the speed difference generated, thereby precisely controlling the tension of each roll material, and the constant tension is taken up to ensure the winding. quality.
With the improvement of people's living standards and the development of science and technology, higher and higher requirements for flexible packaging products are required. The elongation requirements of the film are getting smaller and smaller, and the uniformity of the winding end face is getting higher and higher, which is the film film. Tension control puts higher demands on it. The tension control accuracy of the take-up reel directly determines the elongation of the slitted product and the uniformity of the end face, so it is necessary to use the slip shaft.
The use of the differential shaft, the speed of the slitter, the accuracy of winding, the degree of automation, the reduction of preparation time, and the humanization of the operation can be improved. In particular, a variety of cast polyester thin materials having poor tensile strength and large thickness error use a differential shaft, and the difficulty of winding is reduced. The application of the sliding material shaft of the precious material metal foil greatly improves the quality rate and reduces the production cost. Special production costs. Special paper is the earliest application of this technology.
