[0002] The film blowing machine is a processing equipment used to heat and melt plastic and blow it into a film. Usually, the film blown out through the die head and the air ring is a cylindrical film, and then it passes through the herringbone plate to obtain a finished sheet film with a two-layer structure. The film blowing machine can be used to blow high and low pressure polyethylene. The products are widely used in composite films, packaging films, agricultural covering films, textiles, clothing bags or films and other packaging. In the film forming process, it is often necessary to use it in conjunction with a film cooling and forming device.

[0003] According to the description in a film cooling and forming device for a film blowing machine disclosed in the patent website (authorization announcement number: CN215921061U), "The utility model discloses a film cooling and forming device for a film blowing machine, which relates to the technical field of film blowing devices, including a film blowing machine body, a connecting platform is provided on the top of the film blowing machine body, a cooling mechanism is provided on the upper surface of the connecting platform, and a static electricity removing control mechanism is provided on the upper surface of the connecting platform. The cooling mechanism includes a fixing plate 1, and the outer surface of the fixing plate 1 is fixedly connected to the upper surface of the connecting platform. The utility model adopts the coordination between the connecting water inlet pipe, the water inlet pipe, the cooling roller and the cooling pump. First, the cooling water is transported to the connecting water inlet pipe through the water inlet pipe and the water inlet branch pipe by the cooling pump, and the cooling roller is coordinated to cool the blown film. The cooling liquid after absorbing heat is introduced into the cooling pump through the water outlet branch pipe and the water outlet pipe for cooling, so as to avoid the problems of incomplete cooling of the film, adhesion and wrinkles, ensure the production quality of the film, and improve the use efficiency of the device."

[0004] In view of the above description, the applicant believes that there are the following problems:

The coolant after absorbing heat flows back to the cooling pump through the water outlet branch pipe and the water outlet pipe. In actual use, since the cooling drum of the device is fixed in position, films of different thicknesses cannot fit well, thereby affecting the cooling efficiency. At the same time, the device uses the cooling pump to dissipate heat, and cannot cool the cooling pump body, affecting the cooling effect. Therefore, it is necessary to improve a film cooling and molding device for a film blowing machine to solve the above problems. Utility Model Content
