SED-DFX-B — Iodophor Cotton Swab Production Line

Plastic resin is fed into the extruder, melted at high temperature by the screw, and extruded as Φ2.5-2.8 mm tubes. After water-tank cooling and vacuum rounding, a synchronous belt auto-cutter trims sticks to 72 mm (±1 mm tolerance). The sticks feed into the iodophor filling machine: heat-seal end → peristaltic pump iodophor injection → silicone oil addition (10-15 sticks per cycle). Filled sticks pass through the centrifuge to expel air. In the swab machine, a digital-display peristaltic glue pump applies adhesive and cotton strips are wound and formed; sticks pass through a closed-loop hot-air drying oven. A vacuum pump draws composite films together and each swab is roller-pressed and four-side heat-sealed into individual bags.
