step two, pre-filling the plastic-coated wire roll: the single discharging mechanism is driven to move upwards, and the single discharging mechanism is linked with the one-way sealing mechanism to cancel the sealing of the discharging hole (11), so that the plastic-coated wire coil and the supporting shaft enter the one-way sealing mechanism;

step three, positioning and conveying a single plastic-coated wire coil: the rotating disc (4) is driven to rotate by starting the first motor (5), the rotating disc (4) drives the first rotating ring (6), the second rotating ring (7) and the connecting rod (8) to synchronously rotate, so that the positioning mechanism is driven to rotate, and when the positioning mechanism rotates to the position below the discharge hole (11), the positioning mechanism is linked with the single discharge mechanism to discharge a single plastic-coated wire coil and position the discharged support shaft;

step four, coating a water-blocking material: the supporting shaft of a single plastic-coated wire coil is driven by the positioning mechanism to move to the lower part of the coating cover (2), and the surface of the plastic-coated wire coil is coated by the spraying head (3) in the coating cover (2).
