The invention belongs to the technical field of packaging machines, and relates to a self-adjusting type thin film rolling mechanism. The self-adjusting type thin film rolling mechanism comprises a
machine frame provided with a discharging roller and a storage roller, wherein the discharging roller provided with a thin film in a rolling mode, and the discharging roller and the storage roller are tightened through the thin film. The self-adjusting type thin film rolling mechanism is characterized in that the discharging roller is coaxially provided with a friction wheel, a flat plate is hinged to the part, below the friction wheel, of the
machine frame, a wheel yoke is installed at the position, opposite to the friction wheel, of the flat plate, and a balance weight is fixed to the free end of the flat plate. A supporting axle is arranged at the position, above the discharging roller, of the
machine frame, the supporting axle is provided with a rotary table in a sliding fit mode, the rotary table is connected with a wheel pressing rod, and a pressing wheel connected with the
tail end of the wheel pressing rod presses a thin film face of the discharging roller. A
threaded rod is connected to the rotary table, a spring rod is hung on the
threaded rod, and the lower end of the spring rod is connected with the free end of the flat plate. The speed for unrolling the thin film can be adjusted according to thin film faces with different thicknesses.
