Abstract

The invention relates to a combined spinning and drawing machine and a monomer suction device for the spinning machine. The combined spinning and drawing machine includes an extrusion device, a melt piping system, a metering pump, and a spinning device arranged in sequence according to the production process , monomer suction device, cooling device, shaft parts, oiling device, guide wire drafting device and winding device, the monomer suction device is set at the wire feeding end of the cooling device, including suction pipe, injection device and injection In the adsorption area, the suction inlet of the suction pipe is opposite to the filament outlet end of the spinning device, and the suction outlet is connected to the jet adsorption area. The injection device is installed in the jet adsorption area, and its installation height is higher than the suction outlet. The fluid enters the jet adsorption zone. By setting the monomer suction device and using high-pressure water jet to suck the monomer, it overcomes the defect that the monomer crystal adheres to the spinneret and the side air outlet hole in the existing device, which causes the deterioration of spinning conditions and the increase of broken ends. , shorten the production cycle and improve the spinning quality.

Description

technical field [0001] The application belongs to the technical field of spinning machinery and equipment, and in particular relates to a combined spinning and drawing machine and a monomer suction device for the spinning machine. Background technique [0002] Nylon is also called nylon, and its full name is polyamide. It is the third largest synthetic fiber in my country. Its wear resistance is the best among all natural fibers and chemical fibers. It is not only the best choice for down jackets and mountaineering clothes, but also often Blended or interwoven with other fibers to increase the strength and fastness of the fabric. According to the appearance, it can be divided into staple fiber and filament, and according to the nature, it can be divided into civil silk and industrial silk. [0003] The strength of industrial yarn is generally higher than that of civilian yarn, and it is mainly used for cord fabrics, water cloths, industrial cables, fishing nets, conveyor bel...
