Abstract

LA INVENCION SE REFIERE A UNA DISPOSICION EN UNA UNIDAD IMPULSORA (2) PARA UNA UNIDAD DE SELLADO POR ULTRASONIDOS (1). LA UNIDAD IMPULSORA (2) ES DEL TIPO QUE TIENE DE UN NUMERO DE PLACAS DE CERAMICA PIEZOELECTRICAS (7) DISPUESTAS CON CHAPAS METALICAS CONDUCTORAS, INTERYACENTES (8), ACOPLADAS A UNA FUENTE DE C.A. LAS PLACAS CERAMICAS (7) Y LAS CHAPAS METALICAS (8) SON MANTENIDAS JUNTAS CON UN CONTRAPESO (9) MEDIANTE UN TORNILLO DE SUJECION (10) QUE ASEGURA PARCIALMENTE LA UNIDAD IMPULSORA (2) A LA UNIDAD DE SELLADO POR ULTRASONIDOS (1), Y EJERCE PARCIALMENTE UNA FUERZA DE SUJECION EN LA UNIDAD IMPULSORA (2). EL CONTRAPESO (9) TIENE UN DIAMETRO INTERIOR Y UNO EXTERIOR. CON EL FIN DE OBTENER UNA CARGA DE PRESION UNIFORME EN LAS PLACAS CERAMICAS (7), HAY PROVISTA UNA RANURA (12) EN EL DIAMETRO INTERIOR DEL CONTRAPESO (9).
