EXTRUDER EXTRUDING THERMOPLASTIC SYNTHETIC SUBSTANCE |
摘要 |
An extruder press unit for extrusion of a thermoplastic material has at least one output gap in an extruder body, wherein the output gap is formed by an output gap-defining adjustable extruder lip and an opposing gap-bounding lip. This output gap is adjustable with the help of a mechanical coarse adjusting mechanism to a given gap width, and the gap-defining adjustable extruder lip is connected to at least one adjusting element, to which a control and adjusting device for the thickness of the extruded material is associated. The opposing gap-bounding lip is likewise constructed as an adjustable structural component. The coarse adjusting mechanism operates on the opposing gap bounding lip. A field translator is employed as at least one of the adjusting elements and of course in the form of either a piezotransistor or a magnetrostriction translator. The control and adjusting device is set up for a fine adjustment in the range between 0.05 and 0.3 mm, preferably between 0.10 to 0.20 mm. |
