The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, in a preferred embodiment, the film winding apparatus of the present invention mainly includes a driving motor 1, a frame 2, and a winding mechanism 3. The frame 2 is substantially in an "i" shape, and includes a rotating shaft 4 and two support plates 5 symmetrically disposed at two ends of the rotating shaft 4, and the rotating shaft 4 is connected to the output shaft of the driving motor 1, so that the frame 2 can rotate around the rotating shaft 4 under the driving of the driving motor 1.

The quantity of winding mechanism 3 is two, and the symmetry sets up the both ends at backup pad 5, sets up two winding mechanism 3 and can realize rolling in turn, improves the efficiency of film rolling.

The winding mechanism 3 includes a winding roller 6, a winding motor 7, and a speed change unit 8. The supporting plate 5 is relatively provided with a sliding groove 9, two ends of the winding roller 6 are inserted in the sliding groove 9, and the winding roller 6 can slightly slide along the extending direction of the sliding groove 9. The speed changing unit 8 comprises a stopper 10, an elastic member 11 and a pressure sensor 12, the stopper 10 is arranged in the sliding groove 9 and abuts against the winding roller 6, in the embodiment, one side of the stopper 10 abutting against the winding roller 6 is formed into a circular arc-shaped curved surface matched with the winding roller 6, and therefore the stress of the stopper 10 is uniform. Elastic component 11 adopts the spring, and elastic component 11's one end is connected with dog 10, and the other end is connected with pressure sensor 12, and pressure sensor 12 passes through wire and coiling motor 7 electric connection, and pressure sensor 12 can respond to the pressure of winding up roller 6 to dog 10 to the rotational speed of control coiling motor 7.

The specific operating principle of the gear shift unit 8 is as follows: presetting a normal range of pressure of the winding roller 6 on the stop block 10, and when the pressure of the winding roller 6 on the stop block 10 is larger than the set range, indicating that the rotating speed of the winding motor 7 is too high, controlling the winding motor 7 to slow down by the pressure sensor 12 at the moment, so as to prevent the film from deforming or breaking due to too large tension of the winding roller 6 on the film; when the pressure of the winding roller 6 to the stop block 10 is smaller than a set range, the rotating speed of the winding motor 7 is too low, and the pressure sensor 12 controls the winding motor 7 to accelerate the rotating speed, so that the film is prevented from being wrinkled due to insufficient tension, and meanwhile, the winding efficiency is improved. It should be understood that, in specific implementation, the pressure sensor 12 and the winding motor 7 may be controlled by a known control circuit, such as a single chip, which is not described herein.

The slide seat 13 is used for preventing the winding motor 7 from synchronously sliding along the winding roller 6 when the winding roller 6 slides along the sliding groove 9, so that the winding roller 6 is prevented from being stressed unevenly due to inclination, and the winding of the film is prevented from being influenced. It should be noted that, the seat body 15 and the bottom plate 14 can be connected by a known sliding connection method, such as a sliding rail.
