Description

Technical Field

[0001] This utility model belongs to the field of composite material particle production technology, and in particular relates to a particle melting device for the production of LFTD thermoplastic composite material particles. Background Technology

[0002] LFTD (Low Temperature Low Friction Co-melting Processing) particles, as an innovative thermoplastic composite molding technology, have broad application potential in multiple industries due to their high performance, environmental friendliness, and recyclability.

[0003] The production of LFTD thermoplastic composite granules requires multiple processing steps, among which stirring is a crucial process. However, existing granule melting devices have poor stirring performance, easily resulting in uneven stirring of composite materials and low stirring efficiency, which usually requires a significant amount of time. The stirring efficiency greatly affects the granule melting efficiency. Therefore, we propose a granule melting device for the production of LFTD thermoplastic composite granules. Utility Model Content

[0004] The purpose of this invention is to provide a particle melting device for the production of LFTD thermoplastic composite particles. By setting up a mixing section, specifically, a rotating shaft simultaneously drives a spiral conveyor and an upper bevel gear to rotate.

The lower bevel gear drives a collar to rotate, which in turn drives a fixed ring to rotate. The fixed ring then drives several stirring frames to rotate, which stir the composite material, making the mixture more uniform. This significantly reduces the stirring time required and improves the particle melting efficiency. It solves the problems of poor stirring effect in existing particle melting devices, which easily lead to uneven mixing and low stirring efficiency, often requiring significant time and effort. The stirring efficiency also greatly affects the particle melting efficiency.

After melting is completed, the second motor 316 is started to drive the gear 318 to rotate, the gear 318 drives the toothed ring 317 to rotate, and the toothed ring 317 drives the rotating disk 314 to rotate. The rotating disk 314 and the first limiting disk 311 cooperate to drive the opening and closing plate 312 to move outward.
