Spinning machine

Abstract

The utility model relates to spinning equipment, in particular to a spinning machine. The spinning machine comprises a stander, glue supply devices, strip forming devices, spinning devices and winding devices, wherein forming parts of the winding devices are positioned on the outer side of a region between wall plates on two sides of the stander; two ends of spinning rollers are fixed; the winding devices comprise wet cake winding devices and / or wet barrel winding devices and / or wet strand winding devices. The winding devices of the spinning machine are arranged outside, so that the corrosion to strips, the winding equipment and a control system of the winding equipment is low under an acidic environment, and maintenance and manual operation are facilitated; the conventional centrifugal cylinder needs to rotate at high speed, so that the energy consumption is high; however, the winding devices of the spinning machine only need to meet the speeds of the spinning rollers, and other energy consumption is zero, so that the whole spinning machine is low in power.

Description

technical field [0001] The invention relates to a spinning device, in particular to a 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-spinning treat...

AI Technical Summary

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, and cannot obtain wet filaments with weak acidity, the spinning roll integrates structures such as de-drawing, water washing to remove acid, drying and oiling, etc. The structure of the whole machine is complicated and the problem of energy consumption is increased. In particular, a spinning machine is provided so that the filaments will not be polluted by the residual liquid on the spinning roll when winding, the structure of the spinning machine is simplified, and the spinning The overall energy consumption of the silk machine is reduced, and weakly acidic wet silk strips can be obtained as needed
