Polylactic resin production equipment capable of improving tensile strength

Abstract

The invention relates to the technical field of polylactic resin production equipment, in particular to polylactic resin production equipment capable of improving tensile strength. The equipment comprises a device shell, and at least a heating melting device, a stirring device, a plugging device, a rubbing device and a sliding device are arranged in the device shell. The heating melting device comprises a heating shell, a feeding pipe is fixedly connected to the top of the heating shell, a discharging pipe is fixedly connected to one side of the bottom of the heating shell, an inclined baffle and a heating plate are fixedly connected to the interior of the heating shell, the stirring device comprises a stirring shell and a stirring mechanism arranged in the stirring shell, and the stirring mechanism comprises a rotating shaft. Two arc groove strips are symmetrically arranged on the outer side of a cylinder of the rotating shaft in a central symmetry mode, the rubbing device comprises a cylindrical rubbing barrel and a rubbing disc arranged in the rubbing barrel, and a rubbing cavity is formed in the rubbing barrel. The equipment mainly solves the problem of insufficient mixing of the polylactic resin and chemical substances for enhancing the tensile strength of the polylactic resin in the production process.

Description

technical field [0001] The invention relates to the technical field of polylactic acid resin production equipment, in particular to a polylactic acid resin production equipment with increased tensile strength. Background technique [0002] Polylactic acid has good thermal stability, the processing temperature is 170-230°C, and it has good solvent resistance. It can be processed in various ways, such as extrusion, spinning, biaxial stretching, and injection blow molding. In addition to being biodegradable, products made of polylactic acid have good biocompatibility, gloss, transparency, hand feeling and heat resistance. The polylactic acid (PLA) developed by Guanghua Weiye also has certain antibacterial and flame retardancy properties. And UV resistance, so it has a wide range of uses, can be used as packaging materials, fibers and nonwovens, etc., mainly used in clothing (underwear, outerwear), industry (construction, agriculture, forestry, paper) and medical and health fiel...
