FLATTENING STRUCTURE AND VACUUM WINDING-TYPE COATING DEVICE COMPRISING SAME

The present application relates to the technical field of vacuum winding-type coating, and provides a structure for transversely and synchronously flattening a flexible strip in the vacuum winding-type coating process. The flattening structure comprises: a rack; at least a pair of flattening wheels provided on the rack, wherein a film passing channel is formed between all the flattening wheels and a coating roller, boundaries of both sides of a coated flexible strip pass through the film passing channel, and any flattening wheel is adapted to abut against a boundary area of the coated flexible strip; and an adjusting assembly. According to the flattening structure, the flattening wheels have the function of automatically adjusting an initial angle according to an actual use state to adapt to a transverse pull force; after transversely and continuously flattening a strip to reach an equilibrium state, the flattening wheels automatically swing along with the transverse pull force to a smaller angle required for
