Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA LA ELABORACION DE MATERIALES SINTETICOS TERMOPLASTICOS, QUE DISPONE DE UN TORNILLO (13) SINFIN DE ALIMENTACION PARA LOS MATERIALES PLASTICOS DENTRO DE UNA CARCASA (12). LOS MATERIALES A SER PLASTIFICADOS SON SUMINISTRADOS AL TORNILLO (13) SINFIN DE ALIMENTACION MEDIANTE UN DISPOSITIVO (27) A TRAVES DEL ORIFICIO (10) DE ALIMENTACION EN LA CARCASA (12). LA CARCASA (12) DEL TORNILLO (13) SINFIN DE ALIMENTACION ESTA PROVISTA SOBRE SU PARED INTERIOR CON AL MENOS DOS BOLSAS (23,24) AMPLIAS. ESTAS BOLSAS (23,24) SE EXTIENDEN EN LA DIRECCION LONGITUDINAL DEL TORNILLO (13) SINFIN DE ALIMENTACION Y ESTAN SEPARADAS MUTUAMENTE POR MEDIO DE NERVIOS (25,26) ESTRECHOS, CUANDO SE COMPARAN CON LA ANCHURA DE LAS BOLSAS. UNA BOLSA (24) ESTA ABIERTA HACIA EL ORIFICIO (10) DE ALIMENTACION, LA OTRA BOLSA (23) ESTA SELLADA CONTRA EL ORIFICIO (10) DE ALIMENTACION POR MEDIO AL MENOS DE UN NERVIO (25,26) DE LA CARCASA (12) DEL TORNILLO (13) DE ALIMENTACION SINFIN. PARA MEJORAR EL LLENADO DEL TORNILLO (13) SINFIN DE ALIMENTACION, UN DISPOSITIVO (27) DE ALIMENTACION PARA LOS MATERIALES PLASTICOS A SER PROCESADOS ESTA ASOCIADO CON EL TORNILLO (13) SINFIN DE ALIMENTACION. EL DISPOSITIVO (27) DE ALIMENTACION EMPUJA EL MATERIAL PLASTICO DENTRO DEL ORIFICIO (10) DE ALIMENTACION DE LA CARCASA (12) DEL TORNILLO (13) SINFIN CON UN COMPONENTE DE MOVIMIENTO NORMAL CON RESPECTO AL EJE LONGITUDINAL DEL TORNILLO (13) SINFIN DE ALIMENTACION. LA PROFUNDIDAD DE LA BOLSA (24) ABIERTA HACIA EL ORIFICIO (10) DE ALIMENTACION ES AL MENOS CONSTANTE, VISTA EN LA DIRECCION DE GIRO DEL TORNILLO (13) DE ALIMENTACION. DE FORMA ALTERNATIVA O ASOCIADA, UNO DE LOS NERVIOS (25,26) PUEDE SER AJUSTABLE, PARA PERMITIR QUE LA CAPACIDAD DE ALIMENTACION AL TORNILLO (13) SINFIN SEA MODIFICADA DE ACUERDO CON LOS MATERIALES PLASTICOS A SER PROCESADOS.
