Embodiment Construction

[0056] The following are specific embodiments of the invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0057] Such as figure 1 As shown, the granulation process of the polylactic acid bamboo fiber composite material, the granulation process is based on the granulation production line. The feeding screw b2 is connected to the main feeding motor. Of course, in order to improve the stability of the rotation of the feeding screw b2, a gearbox is connected to the output shaft of the feeding main motor, and the feeding screw b2 is connected to the gear box, as well as to the conveying channel. Heating mechanism for b1 heating, the heating mechanism includes a steam pipeline surrounding the outer wall of the delivery channel b1, the steam pipeline is connected to the steam source, and a protective cover is set on the outside of the delive...

Abstract

The invention belongs to the technical field of composite material processing, and in particular relates to a granulation process of polylactic acid bamboo fiber composite material. It solves technical problems such as easy carbonization of bamboo fibers in the prior art. The granulation process of the polylactic acid bamboo fiber composite material comprises the following steps: S1, material preparation; S2, feeding; S3, heating; S4, extrusion; S5, cooling; S6, granulation. The present invention has the advantages of: it can prevent the carbonization of bamboo fiber material caused by long-time high-temperature heating in the conveying channel, and improve the product quality; at the same time, because the path through the conveying channel is shortened, the amount of bamboo fiber added can be increased thereby reducing The cost of producing the main material.

Description

technical field [0001] The invention belongs to the technical field of composite material processing, and in particular relates to a granulation process of polylactic acid bamboo fiber composite material. Background technique [0002] Polylactic acid, bamboo fiber and auxiliary materials can be mixed to produce environmentally friendly materials, which are used in various tableware and other food fields. [0003] When various materials are mixed, the current material mixing is concentrated in one place and then heated to produce the final composite material. [0004] Heating is carried out in the transmission channel, and the above-mentioned mixing will cause carbonization of the bamboo fiber material in the transmission spiral channel due to high temperature heating, which destroys the original performance of the bamboo fiber. [0005] Secondly, for the cooling of continuous extruded materials, the cooling efficiency needs to be further improved. Contents of the inventio...
