[0002] An important construction link of the wrapped cable intermediate joint is wrapping. In order to wrap the wrapping tape tightly and evenly on the cable core, a certain tension needs to be applied to the wrapping tape. During the wrapping process, the stability of the tension will directly affect the uniformity of the cable outer diameter, and then lead to changes in other related properties of the cable. Therefore, the control of the cable wrapping tension is very critical to the production quality of the cable.

The automatic wrapping device of the utility model is mainly used for automatic wrapping of cable joints, which plays an important role in the safe operation of cable joints. The utility model adopts a reliable control method, and generates a winding preload by controlling the unwinding speed and the winding speed of the wrapping tape, and sets the wrapping length to achieve automatic control. At the same time, the isolation tape on the wrapping tape can be separated and reeled.

At this time, the tension on both ends of the tape 13 presents a nonlinear change; in order to keep the tension on the tape 13 constant, the appropriate rotation speed of the third servo motor 14 is obtained through theoretical calculation to keep the deformation and tension of the tape 13 unchanged;
