Načelo protivrtljivega dvojnega vijačnega ekstruderja

Dvojni vijačni ekstruder ima značilnosti prisilnega transportiranja, kratek čas zadrževanja, dobro delovanje izpušnih plinov, enakomerno mešanje in nizko moč. Dvojni vijačni ekstruder je v glavnem sestavljen iz dveh medsebojno povezanih vijakov, ki se vrtita v sodu, zaradi česar se material striže in premika naprej.

Spodaj je analiza načela delovanja dvojnega vijačnega ekstruderja:

Dva vijaka se vrtita v nasprotni smeri, pri čemer sta dva primera: notranja in zunanja. Položaj rotacije navznoter je razmeroma majhen za mreženje dveh vijačnih ekstruderjev v nasprotni smeri. To je predvsem zato, ker od, if the thread od the feeding section is not fully meshed and not fully closed in the longitudinal and horizontal direction, the material is easy to form a pile between the radial clearance od the two screws and above the two screws, thus reducing the free space od the screw groove, and finally affecting the ability od the screw to accept the material from the feeder, not only affects the feeding performance od the screw groove, but also forms a bridge. Secondly, the material with radial clearance od two screws is rotated inward, and the reaction force will press the two screws towards the cylinder wall on both sides, which will accelerate the wear od screw and barrel. In the same way, the two screws od non meshing and non engaging two-screw extruder are inward rotating.

From the appearance, the thread direction od the two opposite rotating screws is opposite, one is left-handed, the other is right-handed, but they are symmetrical. When the material falls on the screw, it will quickly separate to both sides, fill the screw groove, transport forward, and quickly contact with the heat cylinder to absorb heat, which helps to heat and melt the material.
