Description

A kind of spinning technique being applicable to the external high-speed spinning machine of coiler device

Technical field

The present invention relates to viscose filament yarn spinning production technical field, be specifically related to a kind of spinning technique being applicable to the external high-speed spinning machine of coiler device.

Background technology

Extract pure methylcellulose by cellulosic material, be called pulp.With caustic soda, carbon disulfide process, obtain orange-yellow sodium cellulose xanthate, then be dissolved in diluted sodium hydroxide solution, become the spinning solution of thickness, be called viscose glue.Viscose glue after filtration, maturation, after deaeration, carry out wet spinning, coagulating bath is made up of sulfuric acid, sodium sulphate and zinc sulfate.Sodium cellulose xanthate in viscose glue and the effect of sulfuric acid in coagulating bath and decompose, cellulose regenerated and separate out, gained cellulose fibre becomes viscose after washing, desulfurization, bleaching, drying.The one of viscose filament yarn and viscose is also obtained by above-mentioned technique.

In spinning and spinning last handling process, the selection of spinning machine has semicontinuous weaving loom and continuous weaving loom, and from technology and equipment two aspect, these two kinds of spinning machines exist following difference:

1, from the angle of production technology, semi-continuous spinning machine is separated with post processing (post processing comprises washing, oven dry, becomes the steps such as cylinder) spinning, completes separately, semi-continuous spinning machine primary responsibility spinning portion; And continuous spinning machine is that spinning is concentrated in together completed continuously with post processing (post processing comprises washing, oven dry, becomes the steps such as cylinder) operation, continuous spinning be responsible for from spinning to post processing institute in steps.

2, from the angle of device structure, semi-continuous spinning machine comprises glue feed mechanism, thread spraying structure, strand shaping mechanism, spinning roller mechanism, wiper mechanism and winding mechanism, and the product obtained is the spinning cake falling into centrifugal cylinder; And continuous spinning machine has glue feed mechanism, thread spraying structure, strand shaping mechanism, spinning roller mechanism, wiper mechanism, do not have winding mechanism, strand directly enters the mechanism such as drip washing, oven dry, finally obtains the silk cylinder of coiling and molding.

Based on the difference of above two kinds of spinning machines, its respective pluses and minuses are as follows:

1, semi-continuous spinning machine (as shown in Figure 1-Figure 3):

Advantage: owing to there being the post-processing step carried out separately, and the process also having low-temp desulfurization, low temperature long time drying in post-processing step, product has that intensity is high, whiteness is high, the feature that strand is soft beautiful;

Shortcoming: spin speed low, post processing costly, increases production cost.

2, continuous spinning machine:

Advantage: spin speed high, output increased; Spinning and post processing concentrate in together to be carried out, and production cost reduces;

Shortcoming: because strand namely washes namely to dry, strand intensity is low, and whiteness is low, and strand is coarse, quality is not as the product of semi-continuous spinning machine; For increasing strand obvolvent starching, during floss silk dyeing, slurry needs to remove, and increases downstream product production cost; High to raw material (viscose glue) quality requirement.

In prior art modal semi-continuous spinning machine be R535 semi-continuous spinning machine (as shown in Figure 1-Figure 3, comprise frame 1, glue feeder 2, strand shaped device 3, device for spinning 4 and coiler device 5, in device for spinning 4, spinning roller is relative to spinning the operating surface 102 in face 101 for longitudinally arranging), the main flow of its spinning is:

Viscose glue is shaped to strand by spraying in acid bath groove with spinning head after frit through reaction, strand by the drawing-off of drawing-off dish to solidifying roller, strand after the distance of solidifying a fixing turn that roller reels carries out the reaction of a period of time again lifting head to the face of sth. made by twisting acid removing roller, the mode of drip washing of dripping is adopted to carry out disacidify washing to strand above acid removing roller, reel on the acid removing roller distance of a fixing turn of strand imports centrifugal cylinder again, finally obtains spinning cake.

Wherein, spinning roll body is mainly divided into acid removing roller and solidifies roller, each ingot position of spinning machine uses respectively solidifies roller and a pair acid removing roller for a pair, solidify roller and be arranged on the face of spinning, acid removing roller is arranged on sth. made by twisting face, mutually deviate from, the fixed form of roll body is one end and fixes, and the operating surface position that installation direction spins face relative to spinning machine becomes longitudinally installation.Three cylinder air drafts of another now R535 tri-cylinder yarn spinning machine adopt three cylinders with duct exhaust air mode.

Its strand moulding section of existing R535A semi-continuous spinning machine and spinning roll structure and mounting means cannot carry out high speed spinning, and its spinning spins speed at about 70-90m/min.Simultaneously its device structure and mounting means etc. cause that spinning machine equipment floor space is large, energy consumption is high, technological process is complicated, maintenance point is many, the shortcomings such as accessory consumption is large, product cost is high.Three cylinder three cylinders of another R535 tri-cylinder silk mutually form interference with duct exhaust air mode in air draft process, cause exhaust effect poor.

In prior art, modal continuous spinning machine structure as Figure 4-Figure 6, and its first half comprises frame 1, glue feeder 2, strand shaped device 3 and device for spinning 4, and in device for spinning 4, spinning roller is relative to spinning the operating surface 102 in face 101 also for longitudinally arranging.The continuous spinning machine of the Soviet Union improves for spinning roller segment, but producing what obtain due to it is tow, can not obtain spinning cake, so can not directly be applied in semi-continuous spinning machine.

It is CN1356409 that State Intellectual Property Office discloses a publication number in 2000.12.6, name is called the patent of invention of " single channel multifibres is centrifugal to be spun and semi-continuous spinning machine and rayon spinning technique thereof ", a kind of centrifugal semi-continuous spinning machine of this disclosure of the invention, it comprises viscose glue induction system, swing tube assembly, scrape acid, drawing-off dish, solidify roller, acid removing roller, crane and funnel, centrifugal cylinder and electric ingot system, and viscose glue induction system enters the multichannel viscose glue pipe of glue by head and tail two ends simultaneously and supporting mechanism forms; Swing tube assembly by the multi-channel parallel be connected in series with multichannel sebific duct measuring pump, consider overlap, curved tube and shower nozzle form; The acid removing roller assembly be made up of two acid removing rollers above roller, strand walking path being provided with and installing up and down is solidified two; On machine crane, the funnel of device and the same number of synchronization action of strand; Its centrifugal cylinder, electric ingot Operation system setting become the many centrifugal cylinders of every ingot and the electric ingot supporting with it and controlling organization.
