Description

Technical Field

[0001] The utility model relates to the technical field of plastic nylon, in particular to a plastic nylon extrusion device. Background Art

[0002] Plastic is a polymer compound that is polymerized by addition polymerization or condensation polymerization with monomers as raw materials. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeated amide groups 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.

[0003] After searching, the utility model patent announcement number is CN 216635325 U. The application discloses a plastic extrusion device, which relates to the technical field of masterbatch production, and improves the problems of uneven heating and easy cooling and solidification of plastics in current plastic extrusion devices. It includes a conveying pipe, one end of which is fixedly connected to an extrusion head. The present application sets a stepping motor, a first electric heating pipe and a conveying screw, so that when the first electric heating pipe starts working, the molten plastic flowing inside the conveying pipe can be heated through the conveying pipe, and when the stepping motor starts working, the conveying pipe can be driven to rotate by the gear and the gear ring, so that the molten plastic inside the conveying pipe can be conveyed in cooperation with the conveying screw, and finally extruded from the extrusion head. At the same time, the continuously rotating conveying pipe can make the surface of the conveying pipe heated evenly, so that the molten plastic inside the conveying pipe is heated evenly, thereby effectively reducing the probability of cooling and solidification of the molten plastic inside the conveying pipe.
