A main unit machine in the chemical fiber spinning unit; refers to the melt spinning, which is used to further supplement the nascent fibers (including filament or short fiber tow, etc.) obtained in processing, and make It is a special machine that forms a certain package form. Melt-spinning winding machines generally have the following four main components: a wet oiling section, a drawing or wire guide section, a winding section, and an electrical drag and control section. According to the different types of fibers processed, there are various types of melt spinning winders: filament winding machines, short fiber winding machines and industrial yarn winding machines; as far as filament winding machines are concerned, they can be divided into For conventional winding machine (winding speed 1000-2000m/min), high-speed winding machine (3000-4000m/min) and ultra-high-speed winding machine (5000-8000m/min) and so on. Winding machine is mainly used for rubber line, nylon, polyester cord, polyester cord winding, high-tech fiber, coated yarn, artificial grass silk, lithium-ion battery production, coated glass fiber, monofilament, multifilament Flat yarn (single yarn or multi-end yarn winding spindle), staggered spindle and other fields.
