Description

Technical Field

[0001] The utility model relates to the technical field of plastic hot melting, and more specifically, to a high-efficiency hot melting device for thermoplastic polyurethane elastomer. Background Art

[0002] Thermoplastic polyurethane elastomer is also called thermoplastic polyurethane rubber. Thermoplastic polyurethane rubber relies on intermolecular hydrogen bond crosslinking or light crosslinking between macromolecular chains. These two crosslinking structures are reversible as the temperature rises or falls. In the molten state or solution state, the intermolecular force is weakened, and after cooling or solvent evaporation, the strong intermolecular force connects together again, restoring the original solid performance. When producing and processing polyurethane rubber, the raw materials of polyurethane rubber need to be introduced into the hot melt equipment, and the raw materials are extruded and granulated. However, the raw materials of polyurethane rubber currently have different specifications and types. When the raw materials of different specifications are introduced into the raw material bucket, some specifications of raw materials will be stuck at the upper end of the raw material bucket, and workers are required to assist in unloading, which is easy to affect the workers' work safety.
