spinning machine

Abstract

The present invention relates to a spinning equipment, in particular to a spinning machine, comprising a frame, a glue supply device, a filament forming device, a spinning device and a winding device, the forming part of the winding device is located on the machine The outer side of the area between the wallboards on both sides of the frame, the two ends of the spinning roll are fixed, and the winding device includes a wet cake winding device, and / or a wet drum winding device, and / or Wet skein winding device. Due to the external installation of the winding device of the present invention, it is less corrosive to filaments, winding equipment and its control system in an acidic environment, and is convenient for maintenance and worker operation. Since the existing centrifugal cylinder needs to rotate at a high speed, the The energy consumption is high, but the winding device of the present invention only needs to meet the speed of the spinning roller, and has no other energy consumption, so the power of the whole machine is small.

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
