Dry method composite all-in-one machine

The utility model belongs to the technical field of plastic films, and particularly relates to a dry method composite all-in-one machine which comprises a material containing box, an operation box is fixedly installed at the top of the material containing box, a filtering box is fixedly installed at the top of the operation box, a first round roller is movably connected to one side of the inner wall of the operation box, and discs are evenly and fixedly installed on the surface of the first round roller. The number of the discs is two. According to the width of a plastic film, a third threaded rod is used for driving two baffles to relatively move to proper positions, so that the two plastic films are clamped between the two baffles, when the plastic films are put on a first round roller to be conveyed, the vertical positions of the two plastic films can be kept uniform, and therefore it is guaranteed that the two plastic films can be flatly bonded together; and the filter box is arranged at the top of the op
