ULTRASONIC SEALING DEVICE

摘要

Described is an ultrasonic device for sealing material (1) in strips, comprising: a generator (9) of electrical power signals; a converter (9a) for converting the electrical power signals into mechanical vibrations; a sonotrode (2) rotating about a first axis (X2); an anvil (4) rotating about a second axis (X4) parallel to the first axis (X2); the sonotrode (2) having a circular groove (6) and the anvil (4) having a protruding element (7) which is annular in shape; the protruding element (7) is configured to operate in conjunction with the groove (6) along directions parallel to the first axis (X2) and to the second axis (X4) in such a way as to seal the sheet or strip of material (1) moved along a direction (A) transversal to the first (X2) and second (X4) axis of rotation and passing between the sonotrode (2) and the anvil (4) engaging the groove (6) and the protruding element (7).

1. An ultrasonic sealing device, comprising:
an electrical signal generator (9); a converter (9a) for converting the electrical signals into mechanical vibrations; a sonotrode (2) rotating about a first axis (X2) and having a first peripheral surface (3); and an anvil (4) rotating about a second axis (X4) parallel to the first axis (X2) and having a second peripheral surface (5);characterised in that:
one between the first peripheral surface (3) and the second peripheral surface (5) has a circular groove (6); and one between the second peripheral surface (5) and the first peripheral surface (3),respectively, has a protruding element (7) which is annular in shape; the protruding element (7) being configured to engage the groove (6) for a predetermined depth (P) and operating in conjunction at least axially along directions parallel to the first axis (X2) and to the second axis (X4) with the groove (6), in such a way as to seal a material (1) to be sealed, the material being moved along a direction (A) transversal to the first (X2) and second (X4) axis and passing between the sonotrode (2) and the anvil (4) engaging the groove (6) and the protruding element (7).
