Although the technical scheme can joint the new film and the old film together, the precise butt joint is difficult to realize, and the lap joint of the new film and the old film cannot be realized.

Although the device of the technical scheme can butt joint the new film and the old film together, the device cannot realize the lapping of the new film and the old film and cannot meet different requirements.
Therefore, how to provide a device that can not only realize the butt joint of the new film and the old film, but also realize the lap joint of the new film and the connecting film to meet different requirements, and precisely joint the new film and the old film has become a technical problem to be solved at present.
