SED-118SP-F — Automatic Plastic Ampoule Oral-Liquid Filling and Sealing Machine

Roll-fed PVC/PE laminate (0.2–0.4 mm × 120 mm) feeds from the discharge roller through an elastic tension roller. Two parallel film webs pass into the heating roller and forming station, where the forming blower inflates two layers of softened film between matched cam-driven molds to form a chain of joined inverted ampoules. Molds are continuously cooled. The filling station's 5 parallel filling heads (electronic peristaltic pump or mechanical piston pump) drop into the open tail of each ampoule and dose 1–50 mL with electromagnetic valves. The cam-driven heat-sealing knife and shim plate close the tail; an indentation cutter scores each ampoule's perforation strip; a blanking cutter punches each ampoule from the web (waste blown out); a slit station separates batches. Stations 3–5 share two parallel rotating shafts driven by motor + reducer.
