Through setting up first air supporting roller 61 and second air supporting roller 62, the air supporting roller is the non-cladding material one side process that the membrane was rolled up, guarantees that the cladding material face that the membrane was rolled up does not take place the fish tail with the air supporting roller, solves the easy scratch's of membrane roll surface problem. The moving mechanism 40 is arranged to drive the winding roller 4 to reciprocate in the horizontal direction, so that the pressure direction between the winding roller 4 and the main hub 3 is the horizontal direction, the pressure direction and the pressure between the main hub 3 and the winding roller 4 are kept unchanged when the film roll changes along with the winding diameter, the problems that the tightness degree of the film roll is inconsistent and the tension is large or small in the prior art are solved, and the problem that the end face of a part of the film roll is not flat in the prior art is solved. The film rewinding machine has the advantages of being simple and compact in overall structure, small in occupied space, high in working efficiency and good in rewinding effect, and capable of guaranteeing that a film roll has high stability and smoothness in the rewinding process.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
