Abstract
Description
Technical Field
[0001] The utility model relates to chemical fiber spinning equipment, in particular to a novel screw extrusion device. Background Art
[0002] Screw extruders are often used in the chemical fiber textile industry. The general spinning process is to put the raw materials into the feed pipe through the suction metering device and then transfer them to the screw assembly. After melting, they are transported to the next process. The high-speed rotation of the screw during use will generate a lot of heat. The raw materials are easy to stick to each other at the screw entrance, and the raw materials are also easy to stick to the inner wall of the screw assembly, which will seriously affect the product quality and even cause damage to the equipment. Summary of the invention
