[0044] See also Figure 1, the film feeding device provided in the embodiment of the present application is now described. The film feeding device includes a frame 1, a feed roll 11, a first tension roller 2, a first tension adjustment component 3, a second tension roller 4, a film feeding platform 5, a second tension adjustment component 6 and a feed roll 12. The feed roll 11 is rotatably mounted on the frame 1 and is used to release the film strip 7. The first tension roller 2 is rotatably mounted on the frame 1 and is disposed on one side of the film feeding platform 5 to detect the tension of the film strip 7 at a first position. The first tension adjustment component 3 is mounted on the frame 1 and is disposed between the feed roll 11 and the first tension roller 2 to adjust the tension of the film strip 7 at the first position. The second tension roller 4 is rotatably mounted on the frame 1 and is disposed on the other side of the film feeding platform 5 to detect the tension of the film strip 7 at a second position. The film feeding platform 5 is mounted on the frame 1 and is disposed between the first tension roller 2 and the second tension roller 4 to support the film strip 7 to achieve film cutting operations. The second tension adjustment assembly 6 is mounted on the frame 1 and positioned between the take-up reel 12 and the second tension roller 4. It is used to adjust the tension of the film strip 7 at the second position. The take-up reel 12 is rotatably mounted on the frame 1 and is used to wind up the film strip 7. The pay-out reel 11 rotates to unwind the film, driven by a motor or other drive element, while the take-up reel 12 rotates to rewind the film.
