Control system of semi-continuous and high-speed spinning machine

Abstract

The invention relates to a control system of a semi-continuous and high-speed spinning machine. The control system comprises a central control module, a glue supply control module, a thread-line forming control module, a spinning control module and a winding control module, wherein the central control module is respectively connected with the glue supply control module, the thread-line forming control module, the spinning control module and the winding control module; the spinning control module controls formed thread-lines to walk to a spinning roller which is transversely arranged relative to an operation face of a spinning surface, and the formed thread-lines surround the spinning roller; the spinning control module controls a spinning device to draft, solidify and disacidify the thread-lines by controlling rotation of the spinning roller, and in the processes of drafting, solidifying and disacidifying the thread-lines, the spinning control module controls a washing device to wash the formed thread-lines; the spinning control module controls the formed thread-lines which are drafted, solidified, disacidified and washed to be guided out of the spinning roller to the interior of a hopper. The control system of the semi-continuous and high-speed spinning machine improves the spinning speed, ensures response and walking path of the thread-lines and also ensures the full response of the thread-lines.

Description

technical field [0001] The invention relates to the control of a spinning process, more specifically, the invention relates to a control system of a semi-continuous high-speed spinning machine, which belongs to the technical field of semi-continuous spinning machine spinning. 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, desulfurizati...

Problems solved by technology

[0034] The invention aims to solve the problem that the spinning speed cannot be increased due to the short walking distance of the structural filaments and the insufficient reaction in the production of viscose filaments by the existing semi-continuous spinning machine, and provides a control system for the semi-continuous high-speed spinning machine The system can control the operation of each step in the spinning process, so as to increase the spinning speed while ensuring the walking distance of the sliver reaction, and at the same time ensure the full reaction of the sliver, thereby achieving the goal of ensuring quality, improving production efficiency and reducing costs.
