Description

TECHNICAL FIELD

[0001] The application relates to the technical field of TPU base film production and processing, in particular to a TPU base film production and processing device and a processing technology thereof. BACKGROUND

[0002] TPU is a thermoplastic polyurethane elastomer material, which is a kind of fiber material between rubber and plastic. The TPU base film is a base film processed by taking TPU as a raw material. The TPU has excellent physical properties, can be melted by heating and can be shaped by cooling. The TPU not only has the high elasticity of plastic materials, but also has the high strength of engineering plastics, has high toughness, high wear resistance, high elasticity, high toughness, and excellent comprehensive properties such as solvent corrosion resistance, wear resistance, acid and alkali resistance, and strong shock absorption, and is widely used in shoe materials, cables, films, pipe fittings, automobiles, medical treatment and other fields. The TPU base film has excellent flexibility, stretchability and elasticity, and can bring a certain degree of protection function.

[0003] The production process of the TPU base film mainly includes raw material preparation, mixing, extrusion, cooling, cutting and packaging. When the extruded film is cooled, a cooling roller is generally used for cooling. Since the cooling roller generally directly cools the entire arc-shaped roller surface through a spiral heat conduction pipeline, the cooled arc-shaped roller surface contacts the film and cools it. Therefore, the cooling utilization rate of the cooling roller is low during the entire cooling process, resulting in high cooling cost of the TPU base film. When the arc-shaped roller surface of the cooling roller contacts the film, heat is transferred along the arc-shaped roller surface and the heat conduction pipeline in the cooling roller, resulting in an increase in the temperature of the arc-shaped roller surface of the cooling roller and a decrease in the cooling effect of the cooling roller.
