Description
мера в цилиндрический канал корпуса 3. Пружина 4 при этом вращаетс посредством шестерен 9, 10 и втулок 5, 6.measure into the cylindrical channel of the housing 3. The spring 4 at the same time rotates by means of gears 9, 10 and sleeves 5, 6.
Расплав полимера захватываетс витками пружины 4, котора , распредел его по трубе , нагнетает в сторону мундштука 7. .В момент , когда расплав полимера выйдет за торец эластичной диафрагмы 8, трубе сообш,аетс осевое перемеш,ение. Расплав равномерно обволакивает трубу по поверхности и калибруетс по толш,ине эластичной диафрагмой 8, внутрь которой подаетс охлаждающа жидкость под давлением. Трубы подаютс через нагреватель 12 и пружину 4 непрерывно торцами впритык. Скорость врашени пружины и скорость перемещени труб синхронизированы с производительностью экструдеров.The polymer melt is captured by the coils of the spring 4, which, distributing it through the pipe, forces it towards the mouthpiece 7. At the moment when the polymer melt leaves the end of the elastic diaphragm 8, the pipe is axially mixed. The melt uniformly wraps the pipe over the surface and is calibrated in thickness, and not by an elastic diaphragm 8, into which coolant under pressure is fed. The pipes are fed through the heater 12 and the spring 4 continuously end-to-end. The spring speed and the tube speed are synchronized with the extruder capacity.
