Problems solved by technology

Because many additives and fillers are added to engineering plastics, the additives and fillers need to be dried in a drying cylinder for several hours before being put into the extruder after mixing. During drying, the additives and filler particles are easy to agglomerate due to the long-term standing of the materials. , leading to uneven mixing of materials in the melting zone of the extruder, and the quality of the finished engineering plastics obtained after extrusion is not good

Abstract

The invention discloses a high-frequency resonance fusion extruder for engineering plastic preparing. The high-frequency resonance fusion extruder comprises an extruder body and a resonance material barrel arranged on the extruder body. The resonance material barrel comprises a barrel body and a cover. The barrel body is of a hollow cylinder structure, the lower end is gradually shrunk, the upperend and the lower end of the barrel body are opened, and the opening in the lower end of the barrel body is a feeding port. The cover is connected with a rotation rod, and an ultrasonic transmitting rod is arranged in the rotation rod. The high-frequency resonance fusion extruder for engineering plastic preparing is provided with the resonance material barrel, materials pass through the resonancematerial barrel, after the materials are subjected to ultrasonic resonance in the material barrel, material particle mixing is more uniform, and the quality of engineering plastic finished products isgreatly improved.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics preparation equipment, in particular to a high-frequency resonance melting extruder for engineering plastics preparation. Background technique [0002] Engineering plastics have excellent comprehensive performance, high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time, and can replace metals as engineering structural materials. . With the increasing application of engineering plastics, people have put forward higher requirements for the performance of engineering plastics. [0003] An extruder is needed in the production process of engineering plastics. The mixed material is melted in the extruder and then extruded, then cooled and granulated. Because many additives and fillers are added to engineering plastics, the additives and fillers need to be dried i...
