اصل اکسترودر پیچ دوقلو ضد چرخش

2021-06-07

اکسترودر دوقلو دارای ویژگی های انتقال اجباری ، زمان کوتاه اقامت ، عملکرد خوب اگزوز ، اختلاط یکنواخت و قدرت کم است. اکسترودر دو پیچ عمدتا از دو پیچ مش بندی متقابل تشکیل شده است که در بشکه می چرخند و مواد را مجبور به برش و حرکت به جلو می کند.


در زیر تجزیه و تحلیل اصل کار اکسترودر ضد پیچ ​​دو پیچ است:

 

دو پیچ در جهت مخالف می چرخند ، که در آن دو حالت وجود دارد: چرخش داخلی و چرخش به بیرون. وضعیت چرخش به داخل برای مش بندی اکسترودر دو پیچ با جهت مخالف نسبتاً کوچک است. این عمدتا به این دلیل است از, if the thread از 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 از the two screws and above the two screws, thus reducing the free space از the screw groove, and finally affecting the ability از the screw to accept the material from the feeder, not only affects the feeding performance از the screw groove, but also forms a bridge. Secondly, the material with radial clearance از 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 از screw and barrel. In the same way, the two screws از non meshing and non engaging two-screw extruder are inward rotating.

 

From the appearance, the thread direction از 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.
