Preparation method of double-core twisted shielding cable

The invention relates to the technical field of cable production, and discloses a preparation method of a double-core twisted shielded cable, a smearing and drying mechanism comprises a mounting table, the top of the mounting table is fixedly connected with a mounting frame, one side of the mounting frame is fixedly connected with a first motor, and the first motor is fixedly connected with a second motor; according to the preparation method of the double-core twisted shielded cable, the first motor drives the first rotating shaft to rotate forwards and backwards in a reciprocating mode, the first rotating shaft drives the first processing pipe to rotate in a reciprocating mode through the first gear and the second gear, and the first processing pipe is driven to rotate in a reciprocating mode through the first gear and the second gear. Meanwhile, a second processing pipe is driven to rotate through a transmission mechanism, meanwhile, through cooperation of a spraying mechanism and a drying mechanism on a fi
