Abstract

The invention relates to polyglycolic acid drying equipment. The polyglycolic acid drying equipment comprises a base, a drying box, a winding device and an unwinding device. The winding device and theunwinding device are arranged at the two ends of the base correspondingly. The drying box is arranged in the middle of the base. A drying drum is arranged in the middle of an inner cavity of the drying box. The outer wall of the drying drum is provided with a locating seat. The two sides of the locating seat are provided with mounting grooves. Drying fans are mounted in the mounting grooves. Theupper and lower ends of each mounting groove are provided with heating wires. The drying drum is internally and horizontally provided with a plurality of heating chambers. The heating chambers communicate with the mounting grooves through a plurality of vent ports. The drying drum is internally provided with a plurality of electric heating bars. The electric heating bars are distributed in the periphery of each heating chamber. The end, close to the winding device, of the drying box is provided with a line outlet. The end, close to the line outlet, of the interior of the drying box is providedwith two line guide rolls. The two line guide rolls convey suture lines output from the drying drum to the winding device through the line outlet. Thus, the drying equipment can heat the multiple suture lines simultaneously and greatly improves the drying efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical wires, and in particular relates to a polyglycolic acid drying device. Background technique [0002] Polyglycolic acid (PGA), an ideal fully biodegradable material, can be completely degraded within 1-3 months, non-toxic and harmless, and the final degradation products are carbon dioxide and water, which have been obtained in the United States, the European Union and Japan. Biodegradable plastic material certification. PGA is currently mainly used in high-end medical fields such as absorbable surgical sutures, and relies on imports from the United States and Japan. It has good biocompatibility, gas barrier properties, and machinability, and currently has good application and industrialization prospects in medical, oil and gas exploration, packaging and other fields. Suture is one of the most basic and important materials in surgery. It is mainly used for various tissue suturing and hemostasis, ...
