Problems solved by technology

Glass fiber mixed with plastic in twin-screw extruder is still an important way to enhance the performance of plastics. When glass fiber enters the glass fiber port, it is easy to cause glass fiber or materials to return from the glass fiber port due to different entry directions. , so that the glass fiber content is not uniform. In the current production, the direction of the glass fiber is generally adjusted manually and then fixed with a stick, a drawstring or a pipe. To prevent sticks, pull ropes or pipes from falling, it is not only time-consuming and labor-intensive, but also inefficient, and the quality of the product cannot be guaranteed

Abstract

The invention discloses a glass fiber guiding device of a double-screw extruder. The double-screw extruder comprises a double-screw extruder body; a discharging opening is formed in one side of the double-screw extruder body; a feeding opening and a glass fiber opening are formed in the upper surface of the double-screw extruder body; and the double-screw extruder body is provided with a guiding device. The glass fiber guiding device of the double-screw extruder is provided with a guiding ring, a main rod and a branch rod, and the purpose of guiding glass fibers is achieved; a square guiding hole and a guiding body cooperate, and the purpose of guiding the glass fibers is achieved; by a guiding groove and a guiding hole, the purpose of guiding the glass fibers is achieved further; by the guiding device, the glass fibers can be fixed by sticks, digging ropes or tubes without the aid of manual operation, load of workers is reduced, production efficiency is improved, and quality of products is guaranteed; and by a silica gel mat, the purpose of protecting the glass fibers can be achieved, and the glass fibers can be prevented from being abraded.

Description

technical field [0001] The invention relates to the technical field of plastic extruders, in particular to a glass fiber guide device for twin-screw extruders. Background technique [0002] At present, a large amount of plastic waste is generated in the process of production and life. These plastic wastes cannot be degraded when discarded in the natural environment, causing serious white pollution and damaging the environment. The recycling of plastic waste can, on the one hand, reduce white pollution and protect the environment; on the other hand, it can save resources and improve economic benefits. The way to recycle plastic waste is usually to extrude and granulate the recycled plastic waste to form plastic granules that can be used by downstream industries. Glass fiber mixed with plastic in twin-screw extruder is still an important way to enhance the performance of plastics. When glass fiber enters the glass fiber port, it is easy to cause glass fiber or materials to re...
