Technical Field

[0001] The utility model relates to the technical field of polyester film production, in particular to a heating and mixing device for polyester film production. Background Art

[0002] Polyester film, referred to as PET film, is a high molecular polymer plastic film. Its main raw material is polyethylene terephthalate. This film is made through advanced production processes, including extrusion, casting and biaxial stretching. Due to its excellent physical and chemical properties, polyester film is widely used in many fields.

[0003] For the heating and mixing devices for producing polyester films on the market, most polyester films are prone to uneven distribution of carbon black particles during the production process, and the carbon black particles cannot be evenly mixed with other materials, which eventually causes the black layer of the black polyester film to fall off. In addition, the polyester film needs to be heated and mixed during preparation. Ordinary polyester films heat the inner wall shell through the heating layer, which makes the heating of the mixing shell single, and thus the heating and mixing devices for producing polyester films need to be improved.

[0007] Furthermore, both left and right sides of the top of the mixing shell are connected to a feed hopper, and the bottom of the mixing shell is connected to a discharge hopper, and a control valve is arranged inside the discharge hopper.

[0008] Furthermore, the left side of the top of the mixing shell is connected to a water inlet pipe, and the right side of the top of the mixing shell is connected to an air inlet pipe.

[0009] Furthermore, one end of the water inlet pipe is connected to the liquid material required for the production of the polyester film, and one end of the air inlet pipe 7 is connected to the hot air.

[0010] Furthermore, both sides of the support disc are connected with cross bars, the side edges of the cross bars are fixedly connected with scraper frames, and one side of the cross bars is provided with a pump body.

[0011] Furthermore, the bottom of the cross bar is connected to a nozzle, and the number of the nozzles is several.

[0012] Furthermore, through holes are provided in the left stirring shaft and the right stirring shaft, and a circular hole is provided in the connecting rod.
