Abstract

SE DESCRIBE UN DISPOSITIVO PARA INYECTADO DE UNA CUBIERTA DE PLASTICO EN UN TUBO DE PAPEL CON UNA UNIDAD DE INYECCION GENERAL (2) CON TOBNERAS, ESPIRAL DE EXTRUSION IMPULSADA (4), CILINDRO PLASTIFICADO (13) Y CON UN DISPOSITIVO DE FIJACION POR IMPACTO DEL PLASTICO (22), CON LO QUE LAS TOBERAS SE CONECTAN CON EL CILINDRO PLASTIFICADO (13) Y SE COMPRENDE DESDE EL EXTERIOR AL MENOS PARCIALMENTE DESDE DOS PIEZAS DE MOLDEO EXTERIORES MOVILES Y SE FORMA LA PIEZA DE MOLDEO INTERIOR POR UN MANDRIL MOVIL. PARA DISMINUIR EL COSTE TECNICO Y SIMULTANEAMENTE CONSEGUIR EL MEJOR CUMPLIMIENTO DE LAS NECESIDADES HIGIENICAS EN TALES MAQUINAS, ESPECIALMENTE EN LA ZONA MEDIA DE VIDA, SE PROPONE SEGUN EL INVENTO QUE EL CILINDRO PLASTIFICADO (13) Y LAS TOBERAS SE FIJEN ESTACIONARIAMENTE EN EL ARMAZON DE LA MAQUINA (1), DE MODO QUE LA ESPIRAL DE EXTRUSION (11) SE IMPULSE DESDE UN ELECTROMOTOR (20) Y QUE EL DISPOSITIVO DE IMPACTO DE PLASTICO (22) MUESTRE UNA PALANCA (23) DE DOS BRAZOS IMPULSADA POR UNA UNIDAD DE FUERZA EN MANDO (25) EN CONTACTO CON LA ESPIRAL DE EXTRUSION (11) MOVIL EN DIRECCION A SU EJE LONGITUDINAL.
