Abstract

The invention relates to the field of film production, in particular to a PVA film blow molding machine. The PVA film blow molding machine comprises a base, a moving mechanism is arranged on the edgeof one side of the upper surface of the base, the moving mechanism and the upper surface of the base are jointly and fixedly connected with a supporting mechanism, and a driving mechanism is arrangedinside the supporting mechanism. The PVA film blow molding machine has the beneficial effects that when one winding drum needs to be replaced, a film is wound on the other winding drum firstly, then aT-shaped sliding block drives a second supporting plate and a second rectangular rod to move, supporting of the second rectangular rod to the winding drum and limiting of a limiting ring to the winding drum are relieved, at the moment, the wound winding drum can be taken down from a first supporting rod and replaced with a new winding drum, the second supporting plate and the second rectangular rod are reset to support and limit the winding drum, overall replacement is simple and convenient, shutdown is not needed, and film production is prevented from being delayed.

Description

technical field [0001] The invention relates to the field of film production, in particular to a PVA film blow molding machine. Background technique [0002] The film blowing machine is the equipment for producing PVA film. The PVA film is blown and formed into a material roll, and then the material roll is rewound by the winding equipment, which is convenient for the storage and transportation of the PVA film. [0003] However, after the winding operation of the PVA film is completed, the winding equipment needs to take off the winding drum and replace it. The existing winding equipment generally needs to stop the winding equipment when changing the winding drum. To take down the reel and replace it, and the film is easy to deform during the blowing process during the stop process, which will have a certain impact on the quality of some films, and at the same time, the replacement process will affect the production of the film Efficiency, it is necessary to propose a kind ...
