Embodiment 1

[0133] A kind of coarse denier silk spinning process of semi-continuous high-speed spinning machine, comprises glue supply, filament molding, spinning and winding, and described spinning is finished by spinning device 4, and spinning device 4 comprises 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, coagulation rollers, and Roller 405 and acid removal roller 406 complete the drafting, coagulation and acid removal in the spinning step under the rotation of spinning roller 40; combination:

[0134] The speed of the drafting roller 404 is controlled to be 750r / min; the speed of the coagulation roller 405 is controlled to be 850r / min; the speed of the acid removal roller 406 is controlled to be 900r / min.

[0135] The speed of the drafting ro...

Embodiment 2

[0143] On the basis of embodiment 1, concrete process route is:

[0144] 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

[0146] On the basis of embodiment 1, preferred:

[0147] 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 are connected with a driving device to rotate.

[0148] Further, the three spinning rollers 40 are respectively connected with the driving device, which can realize independent and real-time speed-adjusted rotation.

[0149] 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 heavy-denier-yarn spinning technology of a semi-continuous and high-speed spinning machine, and belongs to the technical field of spinning of the semi-continuous and high-speed spinning machine. The technology comprises the steps of glue supplying, thread-line forming, spinning and winding. The spinning is finished through the spinning device, the spinning device comprises three spinning rollers which are transversely arranged relative to an operation face of a spinning surface, the three spinning rollers are respectively a drafting roller, a solidifying roller and a disacidifying roller, thread-lines sequentially surround the drafting roller, the solidifying roller and the disacidifying roller, and the drafting, the solidifying and the disacidifying in the spinning steps are finished under the rotation of the spinning rollers. The heavy-denier-yarn spinning technology of the semi-continuous and high-speed spinning machine solves the problems that due to the fact that response of thread-lines of a semi-continuous spinning machine in the prior art is insufficient, the spinning speed can not be accelerated, and the production efficiency and the product quality can not be improved at the same time; by changing the arrangement direction of the spinning rollers, the thread-lines can walk a longer distance while the spinning speed of the spinning machine is accelerated and structures of other parts of original equipment are not changed, the thread-lines and acid bath react more fully, and the production efficiency and the product efficiency can be improved at the same time.

Description

Technical field [0001] The present invention involves a spinning technology. More specifically, the invention involves a semi -continuous high -speed spinning machine, which is a semi -continuous spinning wire spinning technology field. Background technique [0002] Pure nailulose is extracted from cellulose raw materials, which are called pulp.Treatment with alkaline and disposol carbonide, orange -yellow cellulose sodium talcate is obtained, and then dissolved in a dilute sodium oxide solution, which becomes a viscous spindle raw liquid, called sticky glue.After filtering, cooked, and off -bubbles, the sticky glue is performed by wet spinning. The solidified bath is composed of sulfuric acid, sodium sulfate and zinc sulfate.The cellulose talcate in the sticky glue decomposes the sulfuric acid in the solidified bath, and the cellulose is regenerated and precipitated. The cellulose fiber is washed, desulfurized, bleached, and dry.The chornes of sticky filaments, that is, the type...
