Description

Technical Field

[0001] The utility model relates to the technical field of nylon 66 production, in particular to a nylon 66 pelletizer. Background Art

[0002] Nylon 66, or polyhexamethylene adipamide, -[NH(CH2)6NHOC(CH2)4CO]n-, abbreviated as PA66, is one of the earliest developed, largest-volume, and most widely used varieties in the polyamide family. Nylon 66 is a colorless, transparent, semi-crystalline thermoplastic polymer with excellent mechanical properties, wear resistance, self-lubricating properties, corrosion resistance, and good molding processability. However, it has high water absorption, low modulus, poor dimensional stability and electrical properties, and its heat resistance, light resistance, low-temperature impact resistance, and dyeability need to be improved, which limits the scope of application of nylon 66. In order to expand the scope of application of nylon 66, nylon 66 is usually enhanced and modified, that is, modified nylon 66. Glass fiber has the advantages of insulation, heat resistance, weather resistance, corrosion resistance, and high mechanical strength. Its performance characteristics complement those of nylon 66. At the same time, it has poor processability and is cheap. It is a commonly used nylon reinforcement and modification material.

[0003] When producing modified nylon, it is necessary to first add the additive to nylon 66, and melt-mix the additive with nylon 66. After stirring and mixing, nylon 66 and the additive are mixed. After mixing, the additive and nylon 66 are melted at high temperature, and glass fiber is added during the melting process. After the three are mixed, the liquid is squeezed into strips by an extrusion mechanism. After the strips are cooled, they are cut into pellets by a pelletizing device to complete the production of reinforced nylon 66.

[0004] However, when pelletizing the strip-shaped nylon 66, the material needs to be manually fed to the cutter for pelletizing, which increases the workload of the operator. At the same time, only one strip-shaped nylon 66 can be pelletized at a time, which reduces the efficiency of pelletizing nylon 66. Utility Model Content
