[0001] The utility model relates to the field of calendering mechanisms, in particular to a calendering mechanism for a heat-conducting insulating film. Background Art

[0002] The calendering mechanism of thermally conductive insulating film is mainly used to process and manufacture thermally conductive insulating film. Thermally conductive insulating film is usually used in electronic products, automotive parts, industrial equipment and other fields for heat dissipation or insulation purposes. The calendering mechanism can process the thermally conductive insulating film through the pressure and temperature of the roller to make it have the required thickness, flatness and surface characteristics to meet the requirements of different products. In the calendering mechanism of thermally conductive insulating film, calendering refers to the process of pressing the thermally conductive insulating film into the required thickness and shape through the pressure of the roller.

[0003] However, most traditional calendering mechanisms for thermally conductive insulating films have problems with uneven heating or cooling, and are unable to effectively heat the thermally conductive insulating films. Uneven heating or cooling can cause inconsistent temperatures at different locations on the thermally conductive insulating films, which may cause unstable product quality and affect product performance and reliability.
