Abstract

Head for bottle closing machines, which being of the type that incorporate a body equipped with means of coupling and attachment to the closing machine that receives both axial and rotary movement of the latter, in whose bosom and through bearings is mounted a core topped by its upper end by a closing cone and provided on its periphery with a set of permanent magnets that, together with another set of magnets associated with the housing establish a magnetic field, variable intensity by positional regulation of said magnets, which limits the drive torque for the core by the housing, to establish the level of tightness of the cap on the bottle, is characterized in that the said closing cone, intended to act as a transfer element that moves the plug from the corresponding feeder to the neck of the bottle, incorporates in its side wall a plurality of radial holes, uniform distributed in those that play both elastically retractable lugs, rounded internal end, so that in the maneuver of coupling the cone to the plug, the latter impinges on the said lugs causing the retraction thereof, which later elastic recovery exerts a pressure on the side wall of the cap that holds it stable within the closure cone, having provided for this purpose that as an elastic recovery means for said lugs these are assisted by an O-ring of rubber or other elastic material, housed in a external perimeter groove of the closing cone, towards which the holes or housings of the lugs open and which acts directly on the external end thereof.
