The multi-functional film winding apparatus of claim 1, wherein the rubberizing mechanism comprises a mounting frame, two rotating shafts, a rubberizing assembly, and at least one set of a rubberizing assembly; the two rotating shafts are rotatably arranged on the mounting frame, the axes of the two rotating shafts are parallel to the axis of the rotating shaft, and the two rotating shafts are respectively positioned at the left upper part and the right upper part of the rotating shaft; the glue feeding assembly comprises a first reel, a second reel, two first chucks and two second chucks; the first reel is sleeved on the rotating shaft at the left side, the two first chucks are axially movably arranged on the rotating shaft at the left side, and a first clamping area for locking the first reel is formed between the two first chucks; the second reel is sleeved on the rotating shaft on the right side, the two second chucks are axially movably arranged on the rotating shaft on the right side, and a second clamping area for locking the second reel is formed between the two first chucks; the double faced adhesive tape is wound on the first reel and comprises a tape layer and a lining paper layer which are mutually overlapped, wherein the tape layer is of a fracture type structure or a dispensing type structure; the lining paper layer is fixed on the second reel, and the adhesive tape layer between the first reel and the second reel faces downwards; the glue pressing assembly comprises a lifting component and a pressing plate; the pressing plate is positioned right above the rotating shaft, the upper end of the pressing plate is connected with the mounting frame through the lifting component, the lower end of the pressing plate is provided with an arc surface for adapting to the outer annular surface of the paper cylinder, and rounded transition is arranged between the arc surface and the left side surface and the right side surface of the pressing plate;

When the paper cylinder moves to the position right below the pressing plate, the lifting part drives the pressing plate to press the lining paper layer downwards so as to enable the adhesive tape layer to be in contact with the paper cylinder; and then controlling the paper tube and the two rotating shafts to rotate so that the adhesive tape layers are fully attached to the outer annular surface of the paper tube, and controlling the rotating shafts to continuously rotate clockwise for 120 degrees until the central angle corresponding to the adhesive tape layers on the outer annular surface of the paper tube reaches 30-360 degrees.

6. The multi-functional film winding apparatus according to claim 1, wherein the cutting mechanism comprises a cutter, a lifting assembly and three buffer assemblies; the cutter is arranged at the upper end of the lifting assembly and is positioned right below the rotating shaft; the three buffer assemblies are arranged between the two side plates at equal intervals along the circumferential direction of the rotating shaft, and the three buffer assemblies and the three clamping areas are sequentially and alternately arranged; the buffer assembly comprises a fixed plate, a movable plate, a sliding rod and a buffer spring; a sliding groove is formed in one end, deviating from the rotating shaft, of the fixed plate, and a sliding hole communicated with the sliding groove is formed in one end, close to the rotating shaft, of the fixed plate; the movable plate is movably arranged in the chute along the radial direction of the rotating shaft; the sliding rod is arranged in the sliding hole in a sliding way along the radial direction of the rotating shaft, one end of the sliding rod deviating from the rotating shaft is connected with the movable plate, and one end of the sliding rod, which is close to the rotating shaft, is provided with a limiting part; the buffer spring is arranged in the chute and used for forcing the movable plate to move in a direction deviating from the rotating shaft;

When the paper cylinders full of the films are moved to be aligned with the feeding mechanism, and the next paper cylinder attached with the double-sided adhesive tape is moved to be attached to the films, the movable plate between the two paper cylinders is moved to be right above the cutter, and the films between the two paper cylinders are positioned between the cutter and the movable plate; at this time, the cutter is driven to move upwards by the lifting component, so that the film between the two paper cylinders can be cut off.

7. The multifunctional film winding apparatus according to any one of claims 1 to 6, further comprising a conveyor belt disposed below the feeding mechanism; when the two locking mechanisms at the two ends of the paper tube, which are fully coiled with the film, are controlled to be unlocked, the paper tube, which is fully coiled with the film, automatically falls onto the conveying belt under the action of gravity, so that the paper tube, which is fully coiled with the film, is automatically conveyed to the next station through the conveying belt.
