The specific implementation mode is as follows:

in order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:

referring to fig. 1-5, an edge film unwinding device comprises an unwinding roller 1 for placing an edge film, and when the edge film unwinding device is used, only a winding core of an edge film 4 needs to be sleeved on the unwinding roller 1. Unreel roller 1 touch one side that the roll up direction corresponds on the limit and be provided with and be rectangular frame 2 of rectifying, frame 2 of rectifying including setting up the stock 21 in 4 both sides of limit membrane respectively to prevent that limit membrane 4 from taking place the off normal when going out to roll up. The two ends of the long rod 21 are movably connected with an upper adjusting rod 22 and a lower adjusting rod 23 which are used for adjusting the width of the deviation rectifying frame 2, and the two long rods 21, the upper adjusting rod 22 and the lower adjusting rod 23 form a rectangular frame which can be sleeved on the side film 4 in a surrounding mode. The long rods 21 are movably connected with the upper and lower adjusting rods 23, the distance between the two long rods 21 can be adjusted according to the width of the rolled film, and the application range is wide.

The lower adjusting rod 23 is movably hinged with a fixed bracket 3 which enables the correcting frame 2 to turn over; the fixed support 3 is provided with a plurality of fixed plates 31 for the lower adjusting rods 23 to pass through, and the fixed plates 31 are connected with the lower adjusting rods 23 in a sliding fit manner, so that the whole deviation correcting frame 2 can turn over by taking the lower adjusting rods 23 as a central shaft.
