| titleOfInvention | Barrel screw for processing degradable plastics |
| abstract | The utility model provides a barrel screw rod for processing degradable plastics, includes the barrel and can wear the screw rod of putting in barrel inner chamber, the screw rod includes the body of rod and spiral shell arris, is provided with the feed inlet on the lateral wall of barrel one end, is provided with the discharge gate on the terminal surface of the barrel other end, is provided with the helicla flute on the barrel inner wall that corresponds with the feed inlet, leaves 0.16 ~ 0.27 mm's logical material clearance between the top surface of spiral shell arris at helicla flute place barrel inner wall and screw rod correspondence, has set the adjustable ring that can mediate barrel inner chamber temperature on the barrel outer wall that is close to the feed inlet. The utility model has the advantages that: through the temperature of adjustable ring regulation barrel inner chamber, avoid the material to heat up at the feed section fast, the helicla flute has increased the displacement of the material that gets into the barrel inner chamber, realizes the smooth feeding of material, avoids blockking up the feed inlet, has improved feed efficiency, has reduced the dwell time of material in feed inlet department simultaneously, reduces the influence of the uncertain temperature of feed inlet department to the material. |
