Problems solved by technology

[0033] The present invention aims to solve the problem that the existing semi-continuous spinning machine, especially the production of viscose filaments by the semi-continuous spinning machine, has a short walking distance and insufficient reaction, resulting in the inability to increase the spinning speed. The spinning process of the semi-continuous high-speed spinning machine with spinning rollers can increase the spinning speed and at the same time ensure the walking distance of the sliver reaction, and at the same time ensure that the sliver reaction is sufficient, thereby ensuring quality, improving production efficiency, and reducing costs. the goal of

Embodiment 1

[0129] A spinning process of a semi-continuous high-speed spinning machine with two spinning rollers, including glue supply, filament forming, spinning and winding, and the spinning is completed by a spinning device 4, which includes two Spinning roll 40 that is arranged laterally with respect to the operating surface 102 of spinning surface 101, thread sliver surrounds spinning roll 40, completes drafting, coagulation and deacidification in the spinning step under spinning roll 40 rotation; The rotating speed control combination of root spinning roll 40 is as follows:

[0130] The rotation speed of the spinning roll 40 that the filaments surround first is controlled to be 30r / min, and the rotation speed of the spinning roller 40 that the filaments surround afterward is controlled to be 900r / min.

[0131] The rotation speed of the spinning roll 40 that the filaments surround first is controlled to be 1000r / min, and the rotation speed of the spinning roller 40 that the filament...

Embodiment 2

[0139] On the basis of embodiment 1, concrete process route is:

[0140] The viscose spinning stock solution is supplied with glue through the rubber supply pipe 202, the flow rate is controlled by the metering pump 201, and then enters the spinneret 301 through the filter 203, and the spinneret on the spinneret 301 sprays out filaments, and the filaments enter the tube to form After the device 303 or the bath forming device 302 is solidified and formed, the formed filaments travel to the spinning roll 40 arranged transversely relative to the operating surface 102 of the spinning surface 101, and the filaments surround the spinning roll 40 and are completed under the rotation of the spinning roll 40. Drafting, coagulation and deacidification in the spinning step, in the process of said drafting, coagulation and deacidification, the silk sliver is also washed by water washing device 42, and the silk sliver is exported from the spinning roller 40 and passes through the funnel, I...

Embodiment 3

[0142] On the basis of embodiment 1, preferred:

[0143] The semi-continuous high-speed spinning machine includes a frame 1, and the two ends of the two spinning rollers 40 are respectively fixed above the two sides of the frame 1, and are connected with a driving device to rotate.

[0144] Furthermore, the two spinning rollers 40 are respectively connected with the driving device, so as to realize independent and real-time speed-adjustable rotation.

[0145] The above solution can more easily control the speed coordination of each spinning roller 40, and can realize real-time online speed regulation, and also can change the specifications and types of filaments online without replacing gears and other transmission components.

Abstract

The invention relates to a spinning technology of a two-spinning-roller semicontinuous high-speed spinning machine, and belongs to the technical field of semicontinuous spinning machines. The spinning technology comprises the steps of glue supplying, thread-line forming, spinning and winding, wherein the spinning is carried out through a spinning device. The spinning device comprises two spinning rollers which are transversely arranged relative to an operating surface of a spun surface, thread lines surround the spinning rollers, and drafting, solidifying and deacidification in the spinning steps are achieved when the spinning rollers rotate. The spinning technology solves the problems that thread lines of a semicontinuous spinning machine in the prior art are insufficient in reaction, the spinning process cannot be accelerated, and production efficiency and the product quality cannot be taken into consideration. The arrangement direction of the spinning rollers is changed so that the thread lines can walk for a longer distance while the spinning process of the spinning machine is accelerated and the structures of other components of original equipment are not changed, the thread lines can be reacted with acid bath more fully, and both production efficiency and product quality are taken into consideration.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process of a semi-continuous high-speed spinning machine with two spinning rollers, belonging 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, desu...
