【Sovereign Items】 1. Membrane sealing mechanism for plastic packaging machines, including the film spool (5), the shutter disc (3) on the film spool (5) and the drive connected to the film spool (5). The motor (4) is characterized in that one end of the film winding shaft (5) in the film-receiving mechanism is processed into a thread (5A), and the film film shaft (5) is directly connected with the driving motor (4) through the diaphragm disk (3). A sliding sleeve (6) is arranged on the film film shaft (5), which is in a sliding fit relationship with the film film shaft (5), and 2-4 two-bar linkages are uniformly distributed around the film film shaft (5). The connecting rod is respectively hinged between the sliding sleeve (6) and the diaphragm plate (3), and the opening and closing state of the two connecting rod group is adjusted by the wing nut (1).

[Abstract] The utility model relates to a film-recovering mechanism of a plastic packaging machine, which comprises a film spool whose one end is processed into a thread, which is directly connected with a driving motor through a blocking film disk, and a sliding sleeve is arranged on the film rolling shaft. It is in a sliding fit relationship with the roll film shaft set, and distributes 2-4 two links around the film axis. Each two link is separately hinged to form an adjustable brace structure between the slide sleeve and the diaphragm disk. The wing nut adjusts the opening and closing state of the two-link group.
