Packaging machine

The utility model relates to the technical field of packaging machines, in particular to a packaging machine which comprises a U-shaped mounting frame, a clamping assembly is rotatably connected to the middle of the inner side of the mounting frame, a winding roller is rotatably connected to the upper portion of the inner side of the mounting frame, a cutting assembly is arranged below the winding roller, and the cutting assembly further comprises two sliding seats. And the two sliding seats are symmetrically arranged on the mounting frame. According to the packaging machine, an aluminum profile is clamped through the clamping assembly, then the clamping assembly is rotated to enable the aluminum profile to be wound around a thin film located on the winding roller, meanwhile, an incomplete gear on the clamping assembly is meshed with a rack to drive a sliding block to move, a cutting wire is driven by the sliding block to move, and the thin film is cut off; the incomplete gear is disengaged from the rack afte
