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 of the sliver 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 while ensuring the walking distance of the sliver reaction. At the same time, it can also ensure that the sliver reaction is sufficient, thereby ensuring quality, improving production efficiency, and reducing costs. the goal of

Embodiment 1

[0131] A spinning process of a semi-continuous high-speed spinning machine with three spinning rollers, including glue supply, filament molding, spinning and winding, and the spinning is completed by a spinning device 4, which includes three relative Spinning rollers 40 arranged laterally on the operating surface 102 of the spinning surface 101, the three spinning rollers 40 are respectively drafting rollers 404, coagulation rollers 405 and acid removal rollers 406, and the filaments 8 surround the drafting rollers 404, The coagulation roll 405 and the acid removal roll 406 complete the drafting, coagulation and acid removal in the spinning step under the rotation of the spinning roll 40; the speed control of the drafting roll 404, the coagulation roll 405 and the acid removal roll 406 is The following combinations:

[0132] The speed of the drafting roller 404 is controlled to be 30r / min; the speed of the coagulation roller 405 is controlled to be 900r / min; the speed of the a...

Embodiment 2

[0149] On the basis of embodiment 1, concrete process route is:

[0150] 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 molding 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 filaments are also washed with water by the washing device 42, and the filaments are exported from the spinning roll 40 and passed through the funne...

Embodiment 3

[0152] On the basis of embodiment 1, preferred:

[0153] The semi-continuous high-speed spinning machine includes a frame 1, and the two ends of the three spinning rollers 40 are respectively fixed above the two sides of the frame 1 and connected to the driving device for rotation.

[0154] Further, the three spinning rollers 40 are respectively connected with the driving device, which can realize independent and real-time speed-adjusted rotation.

[0155] The above solution can more easily control the speed coordination of each spinning roller 40, 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 process of a three-spinning-roller semicontinuous high-speed spinning machine, and belongs to the technical field of spinning of semicontinuous spinning machines. The spinning process comprises the steps of glue supplying, silk strip forming, spinning and winding. The spinning is completed through a spinning device, the spinning device comprises three spinning rollers transversely arranged relative to an operating surface of a spinning face, silk strips surround the spinning rollers, and drafting, solidification and deacidification in spinning steps are completed under rotation of the spinning rollers. The spinning process solves the problem that due to the fact that the silk strips of a semicontinuous spinning machine in the prior art reacts insufficiently, the spinning speed cannot be improved, and consideration cannot be given to production efficiency and product quality at the same time; the distribution direction of the spinning rollers is changed, so the spinning speed of the spinning machine is improved, structures of other parts of original equipment are not changed, meanwhile the silk strips can be moved for longer distances and react with acid bath more sufficiently, and the consideration is given to the production efficiency and the product quality at the same time.

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 three 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, de...
