Abstract:
1. A tablet press machine including a fixed casing which houses a compression assembly comprising: a power-driven rotor that rotates about an axis, the rotor including a matrix disc and another two discs on both sides of the rotor, each disc mounting at least one pair of reciprocating punches opposite and aligned with each other, the matrix disc having at least one through matrix where the at least one pair of reciprocating punches is mounted to delimit between the at least one pair of reciprocating punches an empty space of variable size designed to contain a dosed quantity of powder to be compressed; a first set of cams and a second set of cams both associated with the compression assembly and which, as the rotor rotates, impart on the at least one pair of reciprocating punches a driving motion which moves the at least one pair of reciprocating punches cyclically towards and away from each other to compress the powder contained in the matrix in the matrix disc; sealed separating means designed to delimit separate spaces for housing the compression assembly and at least one of the first set of cams or the second set of cams; and releasable connecting means operating between at least one punch and a corresponding set of cams to enable the compression assembly to be removed from the casing separately from at least one of the first set of cams or the second set of cams.
