Abstract
A sealing head for an inductive cap sealing apparatus includes a outer housing containing a coil bobbin supporting a wire coil wound about a magnetic isolator. The coil bobbin and the magnetic isolator can be axially repositioned independently to vary the magnetic field with respect to a container being sealed placed below the sealing head. The housing has a pair of axial apertures containing spring and push rod assemblies connected to a cap plate. The cap plate is spring loaded away from the outer housing so as to clamp the cap and/or seal against the container being sealed.
Claims18
An adjustable sealing head for use with an inductive sealing apparatus, the sealing head comprising:
- a housing defining a cavity that is disposed about and extends along a central axis;
- a coil bobbin disposed in the housing cavity and having a cylindrical support extending along the central axis;
- a wire coil wound about the cylindrical support and capable of producing a magnetic field when energized;
- and
- an adjustment mechanism for attaching the coil bobbin to the housing and enabling the manual adjustment of the coil bobbin in the axial direction with respect to the housing.
An adjustable sealing head for use with an inductive sealing apparatus, the sealing head comprising:
- a housing defining a cavity that is disposed about and extends along a central axis;
- a coil bobbin disposed in the housing cavity and having a cylindrical support extending along the central axis;
- a wire coil wound about the cylindrical support and capable of producing a magnetic field when energized;
- a magnetic isolator disposed within the cylindrical support and adjustable along the central axis with respect to the coil bobbin;
- and
- an adjustment mechanism for attaching the coil bobbin to the housing and enabling the manual adjustment of the coil bobbin in the axial direction with respect to the housing.
An adjustable sealing head for use with an inductive sealing apparatus, the sealing head comprising:
- a housing defining a cavity that is disposed about and extends along a central axis;
- a cylindrical housing defining a central cavity and a pair of axial apertures in the cylindrical wall;
- a coil bobbin disposed in the housing cavity and having a cylindrical support extending along the central axis, the coil bobbin being connected to the housing by an adjustment mechanism enabling manual adjustment of the coil bobbin in the axial direction with respect to the housing;
- a wire coil wound about the cylindrical support and capable of producing a magnetic field when energized;
- a magnetic isolator disposed within the cylindrical support and adjustable along the central axis with respect to the coil bobbin;
- and
- a pair of spring and push rod assemblies disposed in the pair of axial apertures;
- and
- a cap plate connected to the push rods and biased away from the housing.
