Problems solved by technology

Among them, in terms of the composition of the billet, resin, additives and other particles and powders are dynamically and accurately measured by the weight loss scale, and there has been no accurate dynamic measurement measure for the amount of fiber introduction, which makes it difficult to determine the composition of the billet during the production process. Only through billet sampling, Weighing before and after calcining the sample to calculate the fiber content of the billet brings a lag to production activities

Abstract

The invention discloses a real-time monitoring method and device for the fiber content of a thermoplastic blank. The device comprises a fiber fixing ring, a fiber guide wheel, an inductor and a tensioning wheel, the fiber fixing ring and the tensioning wheel are arranged on two sides of the fiber guide wheel, an induction stop block is fixedly installed on the fiber guide wheel, and the inductor is installed near the fiber guide wheel and is matched with the induction stop block. According to dynamic metering of fibers, the feeding amount of the fibers can be monitored in real time in the production process, so that the components of the blank are dynamically monitored, and necessary guarantee is provided for the quality of the product.

Description

technical field [0001] The invention belongs to the technical field of composite material detection, and more specifically relates to a method and a device for real-time monitoring of fiber content of thermoplastic blanks. Background technique [0002] LFT-D is an efficient online molding process for Zhangwei reinforced thermoplastic composite materials. Due to its high production efficiency, energy saving and environmental protection, it is gradually being promoted in the industry. During the implementation of this process, the hot resin and long fibers are mixed and extruded continuously by a screw machine to form a billet, which is transported by heat preservation, grabbed into the mold and directly pressed into a product. Among them, in terms of the composition of the billet, resin, additives and other particles and powders are dynamically and accurately measured by the weight loss scale, and there has been no accurate dynamic measurement measure for the amount of fiber ...
