Abstract

The utility model discloses a packing device which comprises a machine table, a placing rotary table, a lifting frame, a fixing frame and a roller positioning structure. When a wound polylactic acid film is placed on the placing rotary table, the wound polylactic acid film is in butt joint with the sliding barrel, then the motor is started to enable the worm to rotate, then the gear is driven to rotate, and due to the fact that the gear is in meshed connection with the connecting teeth, and the motor frame and the machine box are both fixed in the sliding barrel, the winding speed of the polylactic acid film is increased. When the gear rotates, the sliding cylinder can move downwards along the surface of the stand column to push and press the rotating rod, so that the pressing plate extends outwards to abut against the inner wall of the wound polylactic acid film, the wound polylactic acid film is positioned, and the wound polylactic acid film can be fixed after being positioned. And the situation that the rolled polylactic acid thin film possibly inclines and collapses during rotation is avoided, the situation that a worker needs to position the rolled polylactic acid thin film when placing the rolled polylactic acid thin film is not needed, and packaging convenience is improved.
