High speed spinning machine

Abstract

The invention relates to a spinning device, in particular to a high speed spinning machine. The high speed spinning machine comprises a machine frame, a viscose supplying device, a sliver forming device, a spinning device and winding devices. The forming parts of the winding devices are located on the two sides of the area between two lateral wall plates of the machine frame and on the other side opposite to a spinning face, and the viscose supplying device and the winding devices are located on the outer sides of the wall plates respectively, the winding devices comprise a wet state cake winding device, and / or a wet state cylinder winding device and / or a wet state twist winding device. The winding devices at least comprise a set of spinning rolls, and each set of spinning roll comprises an upper spinning roll and a lower spinning roll responsible for drafting. Due to the fact that the winding devices are arranged outside, in an acid environment, corrosion to sliver forming device, the winding devices and a control system of the sliver forming device and the winding devices is small. The viscose device and the winding devices are located on the outer sides of the wall plates, so that the quantity of the viscose device and the winding devices can be expanded according to different production requirements, and the production capacity of the spinning machine is greatly improved.

Description

technical field [0001] The invention relates to a spinning device, in particular to a high-speed spinning machine. Background technique [0002] Pure methyl cellulose is extracted from cellulose raw material, called pulp. Treat with caustic soda and carbon disulfide to obtain orange-yellow cellulose xanthate sodium, and then dissolve it in dilute sodium hydroxide solution to become viscous spinning stock solution, called viscose. After the viscose is filtered, matured and defoamed, it is wet-spun, and the coagulation bath is composed of sulfuric acid, sodium sulfate and zinc sulfate. Sodium cellulose xanthate in the viscose reacts with sulfuric acid in the coagulation bath to decompose, and the cellulose is regenerated and precipitated. The obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching and drying. Viscose filament is a kind of viscose fiber, which is also made by the above process. [0003] In the process of spinning and post-spi...

Problems solved by technology

[0033] In order to solve the problem that the winding device is easily polluted by water and acidic solution on the spinning roll, the spinning roll integrates structures such as de-drawing, water washing to remove acid, drying and oiling, and there are at least four existing spinning machines. Only one spinning roller can realize the basic function of spinning, which makes the structure of the whole machine complex and increases the energy consumption. In particular, a high-speed spinning machine is proposed, which can ensure that the filaments are not affected by the residual solution on the spinning roller during winding. Pollution, simplification of the structure of the spinning machine, lower energy consumption of the spinning machine, and the ability to obtain weakly acidic wet silk strips according to needs
