[0002] The automotive non-woven fabric hot pressing device is a device specially used to manufacture non-woven fabric materials for use inside vehicles. In the automobile manufacturing process, non-woven fabric materials are usually used to make car seats, door interiors, car roofs, trunk pads and other parts. The automotive non-woven fabric hot pressing device melts and presses the fiber materials together under high temperature and high pressure to form a non-woven fabric material with high strength and stability. It can flexibly meet the requirements of different automotive parts for non-woven fabrics. The design and production standards of automotive non-woven fabric hot pressing devices are usually adapted to the requirements of the automotive industry to ensure that the non-woven fabrics produced can meet the quality and safety requirements of automobile manufacturing.

[0003] According to the retrieval of China Utility Model Publication No.: CN219260480U, a non-woven fabric hot pressing device for vehicles is disclosed. The utility model preheats the non-woven fabric before hot pressing by setting a feed roller group, thereby reducing the water content inside the non-woven fabric; and achieves uniform hot pressing of the non-woven fabric by setting a hot pressing box, thereby improving the hot pressing effect.

[0004] However, there are some issues that need to be considered when implementing the above technical solutions: First, due to the structure of the heating plate and the heating method, the temperature distribution on the plate surface is uneven, resulting in a large temperature difference. Moreover, due to the large temperature lag of the heating plate, the temperature meter cannot collect and control the plate surface temperature in time, resulting in low temperature control accuracy, which will affect the working stability and thus affect the product quality. Secondly, the equipment is directly taken up by the winding roller after hot pressing. The non-woven fabric will be affected by high temperature and pressure, and its fiber structure will undergo certain changes, which will cause the shape and size of the non-woven fabric to deform.
