[0002] During film production, the film needs to be continuously turned over by the air shaft to be wound into a whole roll. In order to improve the production and packaging efficiency, the current turning frame is a double air shaft method. During production, one air shaft is on the production side and the other air shaft is on the waiting side. There are shaft heads on both sides of the air shaft, and the shaft heads are placed on the shaft seat. The top shaft in the shaft seat needs to be pushed onto the air shaft head to lock the air shaft, which is convenient for the subsequent use of the air shaft.
