Sealing and guiding system for a packaging machine

A sealing and guiding system (1) for a packaging machine (M) comprising a processing zone (S), for receiving products to be processed, and an activation zone (N), that are adjacent each other;

• the system (1) comprises:
• a separating wall (2), for separating the processing zone (S) from the activation zone (N);
• at least one movement actuating element (3), that develops from the activation zone (N) to the processing zone (S), crossing the separating wall (2) and has a longitudinal developing axis (H);
• movement actuating means (4), that are arranged in the activation zone (N), for moving the movement actuating element (3) at least along a first direction (D1), transverse to the respective axis (H);
• wherein, with the system (1), the movement actuating element (3) is not subjected to axial translations;
• wherein the separating wall (2) comprises:
• a first part (20) comprising at least a first housing circular seat delimited by a first circular edge;
• at least a first disk (21), which is inserted in the first circular seat so as to be rotatable with respect to the first part (20) and is coplanar with the first part (20);
• the first disk (21) comprises in turn at least a second circular seat delimited by a second circular edge, that is eccentric with respect to the center (O) of the first disk (21);
• and
• at least a second disk (22), which is inserted in the second circular seat so as to be rotatable with respect to the first disk (21) and is coplanar with the first disk (21);
• the second disk (22) comprises, in turn, a third circular seat delimited by a third circular edge, that is eccentric with respect to the center (P) of the second disk (22);
• wherein movement actuating element (3) is inserted in the third circular seat so as to be rotatable with respect to the second disk (22);
• and
• wherein the system (1) comprises rotary sealing means (200, 210, 220), arranged at the first circular seat, at the second circular seat and at the third circular seat, allowing the sealing between the processing zone (S) and the activation zone (N) and the relative rotation of the first disk (21), of the second disk (22) and of the movement actuating element (3).
