Winding device for window sticker processing

The utility model relates to a window sticker processing winding device which comprises a supporting table, two symmetrically-arranged fixing frames are fixedly installed on one side of the top of the supporting table, an adjusting mechanism used for tightening a window sticker again is movably arranged between the two fixing frames, and an auxiliary mechanism used for preliminarily tightening the window sticker is arranged below the adjusting mechanism. An adjusting rod moves downwards, so that a first shifting rod slides on one section of the top of an L-shaped groove, a second shifting rod slides in a sliding groove, and therefore only two rotating frames rotate to be matched with a second guide roller to preliminarily tighten the window sticker; and when the adjusting rod continues to move downwards, the first shifting rod slides on one section of the bottom of the L-shaped groove, so that the two first guide rollers are matched with the second guide roller to tighten the window sticker again, and the tig
