Abstract

The invention discloses a polyglycolic acid spinning assembly, which includes a support and a spiral heating device vertically connected to the support. The spiral heating device includes a heating barrel and a central shaft arranged at the axis of the heating barrel. Hopper, the side of the central shaft is provided with a spiral piece, one end of the central shaft is connected to the motor, the other end is provided with a storage chamber, the storage chamber is provided with a feed port leading to the heating barrel and the end extends to the heating barrel Externally, the lower end of the material storage chamber is connected to the electrostatic nozzle, and the electrostatic nozzle is connected to the high-voltage electrostatic generator. A grounding ring and an air-cooled pipe are arranged in sequence directly below the electrostatic nozzle. The present invention adopts the method of electrostatic spraying to produce filamentous polyglycolic acid. Compared with the traditional extrusion method, the outer diameter of the filaments produced by the present invention can be very small. The present invention implements high-frequency vibration on the polyglycolic acid to be spun through the shock ring, so that the polyglycolic acid liquid is mixed more uniformly, and the indicators in all aspects are more stable, which is beneficial to improving the subsequent spinning effect and efficiency.

Description

technical field [0001] The invention relates to the technical field of polyglycolic acid manufacturing equipment, in particular to a polyglycolic acid spinning assembly. Background technique [0002] Polyglycolic acid (PGA) is an ideal fully biodegradable material, which can be completely degraded within 1-3 months, non-toxic and harmless, and the final degradation products are carbon dioxide and water. It has been obtained in the United States, the European Union and Japan and is safe. Biodegradable plastic material certified. [0003] PGA is currently mainly used in high-end medical fields such as absorbable surgical sutures, relying on imports from the United States and Japan. With good biocompatibility, gas barrier property and machinability, it has been applied in the gas barrier layer of food packaging and used as the raw material of degradable plastic products. It has good application and industrialization prospects. [0004] Polyglycolic acid is usually in the sha...
