▎ 摘 要
NOVELTY - The method involves passing two cable cores extruded by the extruder into the first processing pipe (7) in the smearing and drying mechanism, and smearing and drying the surface of the cable cores with grapheme. The two cable cores are passed into the twisting device (9) to twist the two cable cores. The twisted cable cores are passed into the wrapping mechanism (10) on the mounting platform (1). The wrapping mechanism wraps the shielding layer on the surface of the stranded cable. The wrapped cable is passed into the second processing pipe (8) on the mounting frame (2). The graphene is applied to the surface of the shielding layer tape on the cable that enters the second processing pipe. The cable is passed into an extruder to extrude the insulating layer to obtain a double-core twisted shielded cable. USE - Preparation method of double-core twisted shielding cable. ADVANTAGE - Through the cooperation of the spraying mechanism and drying mechanism on the first processing pipe and the second processing pipe, the shielding layer can be fully and evenly coated and dried during cable processing. The shielding layer is double-layered, which greatly improves the shielding effect of the cable, and also improves the production efficiency of the shielded cable. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the outer structure of double-core twisted shielding cable. 1Mounting platform 2Mounting frame 3First motor 7First processing pipe 8Second processing pipe 9Twisting device 10Wrapping device 21First mounting ring 31Feeding box 41Second mounting ring 51Mounting box 56Air outlet pipe 57Gas distributing pipe 390Discharge pipe 391Liquid pump 392Distributing pipe
