Description

Technical Field

[0001] The utility model relates to the technical field of nylon production, in particular to a mixing device for nylon 6 production. Background Art

[0002] Polyamide is commonly known as nylon (Nylon), and its English name is Polyamide (PA for short). It has a density of 1.15g / cm3. It is a general term for thermoplastic resins containing repeating amide groups — [NHCO] — on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer. It was invented by the famous American chemist Carothers and his research team. Nylon is a term for polyamide fiber (nylon), which can be made into long fibers or short fibers. Nylon is the trade name of polyamide fiber, also known as durable Nylon, whose English name is Polyamide (PA for short), is a basic component of aliphatic polyamide connected by amide bonds - [NHCO] -. The chemical and physical properties of nylon 6 are very similar to those of nylon 66, however, it has a lower melting point and a wider process temperature range. Its impact resistance and solvent resistance are better than nylon 66 plastic, but its hygroscopicity is also stronger. Because many quality characteristics of plastic parts are affected by hygroscopicity, this should be fully considered when designing products using nylon 6. In order to improve the mechanical properties of nylon 6, various modifiers are often added.

[0003] After searching, a Chinese patent with publication number CN202143826U discloses a mixing device for semi-dull nylon 6 production, including a mixer, a motor, and a speed change mechanism. The mixer is provided with a material inlet and a material outlet, and a conveying screw is installed on the mixer cavity between the material inlet and the material outlet. The output shaft of the motor is connected to the input end of the speed change mechanism, and the output end of the speed change mechanism is connected to the input end of the conveying screw. With the above structure, since the mixer cavity between the material inlet and the material outlet is equipped with a conveying screw, the material is stirred by the conveying screw from the time it enters the material inlet to the time it flows out from the material outlet, so that the material obtains great kinetic energy, continuously pushes the mixed material forward, and is always in a state of dynamic mixing and stirring during the conveying process, so that the multiple strands of material strengthen the emulsification, dispersion, homogenization, mixing and crushing effects, so that the mixing is more uniform and no material can remain in the mixer.

[0004] However, the position of the stirring rod of the mixing device for producing semi-dull nylon 6 is also fixed when stirring nylon 6, which reduces the comprehensiveness of stirring of nylon 6 and thus creates a stirring dead angle. Utility Model Content
