SYSTEM FOR MEASURING OUT AND CUTTING COMPACTED POWDERS
FIG1 schematically shows a system for packaging compacted powders in three-dimensional view according to an embodiment of the present invention
FIG1 schematically shows a system for packaging compacted powders 100 according to an embodiment of the present invention. As shown in the figure, the powder packaging system 100 comprises a hopper T having an inlet TP through which powders are conveyed inside the hopper T. In the lower part of the hopper T is placed a screw conveyor C which, due to the rotation around its own axis ac, conveys the powders inside a tube positioned in the lower part of the hopper T and through which the powders are conveyed. As shown in FIG1, the packaging system 100 further comprises a vertical packager which comprises a forming tube TF to make it possible to receive a film coming from a reel B. Like all vertical packagers, also in this case, there is a vertical welder (not represented in FIG1) that allows the vertical welding of the packages and there are members (not present in FIG1) capable of making the film slide towards the lower part of the forming tube TF. The forming tube TF internally contains the second tube TR and consequently also the first tube TC. Therefore, a gap is thus formed between the second tube TR and the forming tube TF. Moreover, the axis of the forming tube TF coincides with the axis of the first tube TC.

packaging system
['1. Compacted powders packaging system (100), comprising a first tube (TC), wherein said first tube (TC) comprises a screw conveyor (C) configured to rotate about an axis (ac) inside said first tube (TC) so as to convey the powders towards an outlet (UT) of said first tube (TC), said system (100) comprises a rotatable terminal (TI, TIC) in proximity to said outlet (UT); said rotatable terminal (TI, TIC) comprising internal cutting means (F) configured to cut the compacted powders going out from said first tube (TC) when said rotatable terminal (TI, TIC) rotates, wherein said rotatable terminal (TI, TIC) is positioned so as to contact the end portion of said first tube (TC) which defines said outlet (UT); wherein said rotatable terminal (TI, TIC) includes an internal opening (AP) which is concentric with said first tube (TC) so as to convey the powders through said opening (AP); wherein said cutting means (F) are positioned within said opening (AP); said system (100) being  characterized in that said internal opening (AP) has a diameter at said outlet (UT) of said first tube (TC) which is equal to the inner diameter of said first tube (TC) at said outlet (UT).']
