[0002] Polyurethane refers to a type of polymer material containing a carbamate characteristic unit in the main chain. This polymer material is widely used in adhesives, coatings, low-speed tires, gaskets, car mats and other industrial fields. In the field of daily life, polyurethane is used to make various foams and plastic sponges. Polyurethane is also used to make condoms and medical equipment and materials. Because polyurethane has a very low thermal conductivity, new wall insulation materials based on polyurethane materials have begun to mature in Western countries such as Europe and the United States.

[0003] In the prior art, a hot melt device is required for hot melting during the processing of polyurethane. However, the traditional hot melt device has relatively simple functions, a slow hot melting speed, and relatively low working efficiency.
