Description
Technical field
The present invention relates to a kind of spinning technique, particularly a kind of spinning technique that is applicable to the semicontinuous high-speed spinning machine of spinning roller horizontally set belongs to the semicontinuous production technical field of spinning of viscose filament yarn.
Background technology
Extract pure methylcellulose by cellulosic material, be called pulp.Handle with caustic soda, carbon disulfide, obtain orange-yellow sodium cellulose xanthate, be dissolved in again in the diluted sodium hydroxide solution, become the spinning solution of thickness, be called viscose glue.Viscose glue after filtration, after the maturation, deaeration, carry out wet spinning, coagulating bath is made up of sulfuric acid, sodium sulphate and zinc sulfate.Sodium cellulose xanthate in the viscose glue and the effect of sulfuric acid in the coagulating bath and decompose, cellulose regenerated and separate out, the gained cellulose fibre becomes viscose after washing, desulfurization, bleaching, drying.Viscose filament yarn is a kind of of viscose, also is to be made by above-mentioned technology.
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 aspects, there is following difference in these two kinds of spinning machines:
1, from view of production technology, semi-continuous spinning machine is that spinning and post processing (post processing comprises washing, oven dry, become step such as tube) separately, are finished separately, and semi-continuous spinning machine mainly is responsible for the spinning part; And continuous spinning machine is that spinning and post processing (post processing comprises washing, oven dry, become step such as tube) operation is concentrated in together and finishes continuously, continuous spinning be responsible for from the spinning to the 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 that obtains is the spinning cake that falls into centrifugal cylinder; And continuous spinning machine has glue feed mechanism, thread spraying structure, strand shaping mechanism, spinning roller mechanism, wiper mechanism, does not have winding mechanism, and strand directly enters mechanisms such as drip washing, oven dry, obtains the silk tube of coiling and molding at last.
Based on the difference of above two kinds of spinning machines, its pluses and minuses separately are as follows:
1, semi-continuous spinning machine (as shown in Figure 1-Figure 3):
Advantage: because the post-processing step that carries out is separately arranged, and also have the process of low-temp desulfurization, low temperature long time drying in the post-processing step, product has intensity height, whiteness height, the characteristics that strand is soft beautiful;
Shortcoming: it is low to spin speed, and post processing expense height increases production cost.
2, continuous spinning machine:
Advantage: it is high to spin speed, and output improves; Spinning and post processing concentrate in together to be carried out, and production cost reduces;
Shortcoming: because strand is namely to wash i.e. baking, strand intensity is low, and whiteness is low, and strand is coarse, and quality is not as the product of semi-continuous spinning machine; For increasing strand obvolvent starching, slurry need be removed during floss silk dyeing, increases the downstream product production cost; To raw material (viscose glue) quality requirement height.
In the prior art modal semi-continuous spinning machine be the 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, the spinning roller is vertically setting with respect to the operating surface 102 that spins face 101 in the device for spinning 4), the main flow process of its spinning is:
Viscose glue sprays in the acid bath groove with spinning head by filter filtration back and is shaped to strand through reaction, strand by the drawing-off of drawing-off dish to solidifying roller, strand carries out rising head again to twisting with the fingers the face acid removing roller after the reaction of a period of time solidifying the reel distance of a fixing turn of roller, the acid removing roller top adopts the mode of the drip washing of dripping that strand is carried out the disacidify washing, strand imports centrifugal cylinder again in the distance of acid removing roller coiling one fixing turn, obtains spinning cake at last.
Wherein, the spinning roll body mainly is divided into acid removing roller and solidifies roller, each ingot position of spinning machine is used a pair of roller and a pair of acid removing roller of solidifying respectively, solidify roller and be installed in the face of spinning, acid removing roller is installed in the sth. made by twisting face, deviate from mutually, the fixed form of roll body is an end and fixes, and installation direction becomes vertically to install with respect to the operating surface position that spinning machine spins face.Now three cylinder air drafts of R535 three cylinder silk spinning machines adopt three cylinders with air channel air draft mode in addition.
Existing its strand moulding section of R535A semi-continuous spinning machine and spinning roll structure and mounting means can't carry out high speed spinning, and its spinning is spun speed about 70-90m/min.Simultaneously its device structure and mounting means etc. cause that the spinning machine equipment floor space is big, energy consumption is high, technological process is complicated, maintenance point is many, shortcomings such as accessory consumption is big, product cost height.Three cylinders, three cylinders of R535 three cylinder silks form mutually in the air draft process with air channel air draft mode and disturb in addition, cause the air draft weak effect.
Modal continuous spinning machine structure such as Fig. 4 in the prior art-shown in Figure 6, its first half comprises frame 1, glue feeder 2, strand shaped device 3 and device for spinning 4, the spinning roller also is vertically setting with respect to the operating surface 102 that spins face 101 in the device for spinning 4.The continuous spinning machine of Soviet Union's system improves for the spinning roller segment, but because its production obtains is tow, can not obtain spinning cake, so can not directly be applied in the 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 " the single channel multifibres is centrifugal to be spun and semi-continuous spinning machine and rayon spinning technology thereof ", this disclosure of the Invention a kind of centrifugal semi-continuous spinning machine, it comprises viscose glue induction system, swing tube assembly, scrape acid, the drawing-off dish, solidify roller, acid removing roller, crane and funnel, centrifugal cylinder and electric ingot system, and multichannel viscose glue pipe and supporting mechanism thereof that the viscose glue induction system is advanced glue simultaneously by head and tail two ends are formed; The swing tube assembly is made up of measuring pump, worry cover, curved tube and the shower nozzle of the multi-channel parallel that is connected in series with the multichannel sebific duct; Two solidify roller above the strand walking path be provided with up and down the acid removing roller assembly of installing of being formed by two acid removing rollers; On the machine crane, the funnel of device and the same number of synchronization action of strand; Its centrifugal cylinder, electric ingot system are set to the many centrifugal cylinders of every ingot and electric ingot and the controlling organization supporting with it.
Foregoing invention can be produced multi-filament simultaneously, increased substantially the output of viscose filament yarn, but this invention is because each ingot position of its spinning machine is used a pair of roller and a pair of acid removing roller of solidifying respectively, solidify roller and be installed in the face of spinning, acid removing roller is installed in the sth. made by twisting face, deviate from mutually, the fixed form of roll body is an end and fixes, and installation direction becomes vertically to install with respect to spinning machine operating surface position.The problem that said structure brings is as follows:
1, said structure has limited the length of roller, viscose filament yarn is short in the time that roller is walked, and the viscose filament yarn curring time is short, if carry high-speed spinning, will inevitably cause the viscose filament yarn reaction time to reduce product quality inadequately, so adopt traditional semi-continuous spinning machine efficient to reduce;
2, in order to raise the efficiency, can process the multi-filament bar simultaneously usually, but many viscose filament yarns hank knotting easily again when being wrapped on the existing spinning roller causes the viscose filament yarn fracture, influences the product quality of viscose filament yarn;
3, in addition, the fixed form of described spinning roller is that an end is fixed, and such fixed form is cantilevered, when the spinning roller rotates, is in a kind of unsure state, breaks down easily;
4, all spinning rollers all are that an end is fixed, certainly will need the extremely complicated transmission mechanism of structure to drive the rotation of spinning roller, so also can cause the rising of fault rate, and changing the silk thread kind, when changing velocity of rotation, need to stop, carry out the replacing of transmission system middle gear again, make production efficiency reduce like this, production cost increases.
It is CN2292097 that State Intellectual Property Office discloses a publication number in 1998.9.23, name is called the utility model patent of " continuous viscose filament spinning machine ", this patent relates to a kind of continuous viscose filament spinning machine, can finish spinning, washing continuously, dry, oil, coiling etc., it spins scooter 120m/min, the utility model arranges the viscose filtration device before the spinning machine board, utilize the spinning machine pump shaft to drive the measuring pump running, it is simple in structure, clean easy to maintenancely, filtered the impurity in the viscose glue effectively; In the spinning bath box spinning head is placed the swing pipe end, guaranteed the concentricity of spinning head and glass tube, can avoid producing lousiness, flexible operation, work efficiency height; The strand twin-steer is adopted in the glass tube exit, has reduced the frictional force between strand and the godet roller, and draw ratio is distributed rationally, becomes the yarn quality height.
Above-mentioned because strand is namely to wash i.e. baking, and 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, slurry need be removed during floss silk dyeing, increases the downstream product production cost; To raw material (viscose glue) quality requirement height.In addition, the spinning roller of above-mentioned continuous spinning machine still is vertically to arrange with respect to workman's operating area, fixes so its mounting means also is an end, still has first piece of problem in the prior art patent.
