Description

Technical Field

[0001] The utility model belongs to the technical field of cast film processing, and in particular relates to a cooling device for cast film production. Background Art

[0002] Cast film is a non-stretched, non-directional flat extruded film produced by quenching the melt. It is characterized by fast production speed and high output. At the same time, the transparency, glossiness and thickness uniformity of the film are excellent. During the production process of cast film, due to the high temperature of heating and melting, the cast film after extrusion also has a very high temperature. Therefore, in order to facilitate its subsequent winding and storage, the high-temperature cast film produced must be cooled by a cooling device. At present, the cooling device used in the production of cast film usually uses a cooling roller to cool the cast film, and the cooling roller is hollow. The roller is made of steel, and a cooling medium is passed into the inside. After a rotating joint is connected at both ends, the cooling medium flows into one end of the cooling roller and flows out from the other end, thereby cooling the cast film. However, when this cooling method is used in practice, due to the rotation of the cooling roller, the flow of the cooling medium in the cooling roller cavity becomes turbulent, which makes the outer surface of the cooling roller prone to uneven temperature, thereby affecting the cooling effect of the cast film. Therefore, in order to solve the above problems, it is necessary to develop a cooling device for cast film production that is easy to operate and has good cooling effect. Utility Model Content
