[0060] A superconducting cable manufacturing apparatus includes a coaxially assembled core wire supply mechanism and a wire braiding mechanism;

[0061] like Figure 9 and Figure 10 As shown, the core wire supply mechanism includes a central tube 1 through which the core wire 100 can pass, and a heating mechanism 11 is provided at the outlet end of the central tube 1; the heating mechanism 11 is a bowl-shaped electric heating sleeve; a positioning ring 12 is also fixed on the outside of the central tube 1, and the positioning ring 12 is located between the heating mechanism 11 and the annular guide rail 2.

[0062] like Figure 3 and Figure 4 As shown, the wire braiding mechanism includes an annular guide rail 2 coaxially fitted to the outside of the central tube 1 and N wire release mechanisms 3 capable of moving along the annular guide rail 2. The annular guide rail 2 can rotate around its central axis and has multiple grooves. A turntable is rotatably installed in each groove, and at least two wire release mechanisms 3 are installed on each turntable. Thus, the movement of the N wire release mechanisms 3 is realized by the rotation of the annular guide rail 2 and the rotation of the turntable. Specifically, each wire release mechanism 3 can revolve around the central axis of the turntable and also around the central axis of the annular guide rail 2. The N wire release mechanisms 3 include X superconducting wire release mechanisms and Y carbon fiber release mechanisms, where Y≤X. Each wire release mechanism 3 includes a mounting frame 31 and a wire guide sleeve 32 set on the mounting frame 31. The wire guide sleeve 32 of the carbon fiber release mechanism is provided with a rotatably connected hot melt adhesive film winding mechanism 4.

[0063] The hot melt adhesive film winding mechanism 4 is configured to spirally wind the hot melt adhesive film on the surface of the carbon fiber 202, and the heating mechanism 11 is configured to heat the hot melt adhesive film at the braiding point of the core wire 100, the superconducting wire 201 and the carbon fiber 202 at the outlet end of the central tube 1.

[0064] In the application, the wire roller 33 is rotatably installed on the mounting frame 31, a guide rod 34 is arranged on one side of the wire roller 33, a first guide wheel 35 is arranged on one side of the guide rod 34, a second guide wheel 36 is further arranged on the side close to the bottom of the mounting frame 31, the wire roller 33 releases the superconducting wire 201 or carbon fiber 202 to the wire guide sleeve 32, and the released superconducting wire 201 or carbon fiber 202 sequentially passes through the guide rod 34, the first guide wheel 35 and the second guide wheel 36.

[0065] In the application, the hot melt adhesive film winding mechanism 4 comprises an inner sleeve 41 and an outer sleeve 42 which are coaxially fixed in the inside of the wire guide sleeve 32 through the bottom disc, symmetrically arranged mounting holes are arranged on the side wall of the outer sleeve 42, a central passage for the superconducting wire 201 or carbon fiber 202 to pass through is arranged in the center of the inner sleeve 41, and a film inlet hole for the hot melt adhesive film to pass through is arranged on the side wall of the inner sleeve 41.

[0066] A hot melt adhesive film roller 43 is arranged in the mounting hole, a mounting rod 44 is rotatably connected in the center of the hot melt adhesive film roller 43, a threaded connector 45 capable of being connected with the inner sleeve 41 is fixed on one end of the mounting rod 44, and a limiting column 46 is rotatably connected on the other end of the mounting rod 44; a limiting screw rod 47 capable of being inserted into the limiting column 46 is connected on the bottom disc.

The wire released by the corresponding wire releasing mechanism 3 is pulled to pass through the central passage of the inner sleeve 41, and the hot melt adhesive film in the central passage is fixed on the surface of the wire.

[0068] In the application, the driven gear 48 is fixed on the outside of the bottom disc, the driving gear 49 driven to rotate by the micro motor is arranged on the mounting frame 31, and one side of the driving gear 49 is engaged with the driven gear 48. With the weaving and forming of the superconducting woven layer 200, the wire is conveyed from the inside of the central passage of the inner sleeve 41 to the weaving position, and at the same time of the wire conveying, the driving gear 49 is driven to rotate by the micro motor, the driving gear 49 drives the driven gear 48 to rotate, and then the synchronous rotation of the inner sleeve 41 and the outer sleeve 42 is realized, and in the process of the rotation, the hot melt adhesive film is spirally wound on the surface of the wire. The conveying of the wire produces a pulling action on the hot melt adhesive film in the process of the spiral winding, thereby driving the hot melt adhesive film roller 43 to rotate, and then releasing the hot melt adhesive film.

[0069] As Figure 7 and Figure 8As shown, the hot melt adhesive film roller 43 is arranged in four arrays, so when connecting four hot melt adhesive films with the wire, the four hot melt adhesive films are arranged in parallel along the axial direction of the wire, so as to ensure that each hot melt adhesive film can realize spiral winding.

[0079] Regarding the preparation of the insulation layer 300, an additional superconducting cable preparation device with the same structure as described above can be added, and a certain natural cooling area is reserved between the two superconducting cable preparation devices. After the superconducting braiding layer 200 is braided and formed, it is transported in the natural cooling area and naturally cooled.
