Introduction Of Slip Shaft Slitting Machine

The principle of the slip shaft is to use the slip slip principle of each slip ring on the slip shaft, so that multiple rolls on the shaft can always maintain constant tension for unwinding and unwinding. Slitting machine (slitting machine) is a device that divides a roll of roll material into multiple rolls, which is widely used. The function of the rewinding shaft is to split the various rolls of various materials from the winding core to the outer layer uniformly, neatly and with constant tension on one or two shafts. However, due to the uneven thickness of the material itself, there is a certain thickness error. After the coil is continuously taken up, the diameter of each coil produces a larger accumulation error. This results in a larger winding speed difference and a greater tension difference between the strips. As a result, the coils are not tight, and the end faces are uneven. In serious cases, the material is scrapped due to excessive tensile force, especially the polyester film. Not only the thickness error is large, but the elongation is large, and it is easy to cause deformation due to tensile deformation. However, the slip shaft has a special structure and consists of multiple slip rings, which can overcome the above phenomenon. During work, the slip ring is controlled to slip with a certain slip torque value (torque), and the amount of slip just compensates the speed difference generated, so that the tension of each roll of material can be accurately controlled, and constant tension can be taken up to ensure the take-up. quality

Now with the improvement of people's living standards and the development of science and technology, higher and higher requirements are imposed on flexible packaging products, the requirements for the elongation of the film are getting smaller and smaller, and the uniformity of the winding end surface is getting higher and higher. The tension control puts forward higher requirements. Therefore, the slitter used in the film type must use a slip shaft. The use of the slip shaft, the speed of the slitting machine, the rewinding accuracy, the degree of automation, the reduction in preparation time, and the humanization of the operation can be improved. In particular, a variety of cast polyester materials with poor tensile resistance and large thickness errors use slip shafts to reduce the difficulty of winding. The winding of precious metal foil with slip shaft application greatly improves the authenticity rate and reduces the production cost. Special production costs. Special paper is the earliest application of this technology.

Slip axis has been widely used in plastic films (including electronics, capacitors, battery films, cling films, packaging, composite films); metal foils (copper foil, aluminum foil, etc.); paper rolls; slitting and winding of PVC sheet rolls . At present, it is continuously extended to other fields, other industries, and slitting and winding of other special materials. The form of winding is center winding, surface winding, surface center winding.发送反馈历史记录
