Description
Technical field
The present invention relates to a kind of textile machine, especially a kind of weaving is with the introducing-type magnetic suspension double twisting energy-saving spindle on the fine spining machine.
Background technology
Ring throstle is a kind ofly will spin good rove, through the machinery of unwinding, drawing-off, twisting, coiling and molding spinning resultant yarn.Be contained in rove on the lift spindle through unwinding, enter draw zone through lever jack, horn mouth, the yarn after the drawing-off passes the steel traveler on twizzle, the rings, is wound up on the bobbin that tightly is enclosed within on the spindle.Bobbin rotates at a high speed under spindle drives, the tension force of yarn drags steel traveler and turns round along rings, at this moment, yarn one end is gripped by front roller nip, the other end again under steel traveler drives around itself axis revolution, steel traveler returns and circles, make steel traveler obtain a turn to front roller nip, because frictional resistance and air drag that steel traveler is subjected on the rings runway make the steel traveler velocity lag in spindle speed, both speed differences have just produced coiling.Simultaneously, because the oscilaltion with the motion of ring rail of rings steel traveler makes spun yarn carry out the taper shape coiling along the length direction of bobbin.Its spinning suiting is strong, and yarn quality is good, and can spinning, it is high to prop up.With regard to its spinning principle, have many advantages.But because of steel traveler high speed rotary on rings under the drive of yarn, steel traveler very easily burns; Steel traveler suffered frictional resistance and air drag on the rings runway, and the suffered air drag of ballooning of yarn (general designation spinning tension), increase with speed strengthens, when spinning tension during greater than yarn strength, cause broken end, these have all limited the further raising of spindle speed, and cop can highlight the contradiction that runs up with large package with the spindle high speed rotating.These contradictions have restricted further developing of traditional ring throstle.
Summary of the invention
Technical problem to be solved by this invention is, a kind of JW introducing-type magnetic suspension double twisting energy-saving spindle is provided, and can directly produce a yarn on fine spining machine, can eliminate the bobbin winder in the conventional spinning flow process, optimizes spinning process.It can be applied to the production of new system fine spining machine, also can transform existing fine spining machine, can also be applied to doubling twisting.When increasing considerably product yield, reducing recruitment, reduce power consumption, and the product quality of corresponding raising.
The present invention realizes like this, it has spindle support JW introducing-type magnetic suspension double twisting energy-saving spindle, spindle blade, yarn-guide tube, duplex bearing, the yarn-guide tube endoporus communicates with the spindle blade endoporus, closely be sleeved on the sleeve pipe on the duplex bearing, the sleeve pipe upper fixed has ceramic ring, can slide up and down pallet in relative rotation at sleeve pipe, the pallet side is fixed with interior alnico magnets, outer alnico magnets hold pallet by internal permanent magnet, the pallet top has roller seat and bobbin carrier base respectively, drum shaft and reverse-flighted screw are housed respectively on the roller seat, be fixed with cylinder on the drum shaft, bearing, gear and rotating disc, yarn-guide mouth is housed on the reverse-flighted screw, bearing and gear (also directly the tankage tube replaces cylinder and reverse-flighted screw), the bobbin support is housed on the bobbin carrier base, on the bobbin support bobbin is housed, bobbin contacts with cylinder (groove drum), the gear that is equipped with on the drum shaft is meshed with gear on the reverse-flighted screw, rotating disc on the drum shaft is corresponding with the rotating disc on the servomotor, be inlaid with the polylith alnico magnets on each rotating disc and (press N, S, N, S is spaced), utilized the principle of inhaling rear-guard before the type of drive of magnetic suspension train, when servomotor rotates, driven cylinder and rotate synchronously; The annular alnico magnets homopolarity that adsorbs on the fixing annular alnico magnets in pallet below and the rail is relative, utilize the principle of magnet homopolar-repulsion, pallet (comprising all objects on the pallet) upwards floats, expansion along with the come-up distance, its mutual expelling force weakens relatively, when mutual expelling force equals the suffered gravity of all objects on pallet and the pallet, pallet suspends fixedly, at this moment, the weight of all objects on pallet and the pallet is pressed on the rail, two-for-one twisting spindles on load has sleeve pipe and yarn-guide tube, and load reduces significantly.
JW introducing-type magnetic suspension double twisting energy-saving spindle has adopted 2 advanced technologies of magnetic suspension train.
1 has adopted the basic principle magnetic suspension of magnetic suspension train
2 have adopted and have scolded (front haulage rear drive) after inhaling before the type of drive of magnetic suspension train
Adopt the JW introducing-type magnetic suspension double twisting energy-saving spindle of said structure, changed traditional ring spinning mode, can directly on fine spining machine, produce a yarn, eliminated the bobbin winder in the conventional spinning flow process, optimize spinning process.
When fine spining machine spinning yarn, yarn enters yarn-guide tube from the ceramic ring that front roller spues through the yarn-guide tube top, pass from the ceramic ring on the sleeve pipe through the spindle blade endoporus, be wound up on the bobbin of cylinder (or groove drum) frictional drive through yarn-guide mouth (or directly through groove drum groove), adjust the driver of servomotor, the speed of its winding speed that drives cylinder (or groove drum) rotation and front roller output yarn is consistent at any time.And because of the characteristic of two-for-one twisting spindles, it revolves to turn around and adds two twists, and output is enhanced about more than once under the equal rotating speed.
When doubling twisting, yarn more than 2 or 2 is drawn doubling plying behind tensioner from bobbin respectively, yarn behind the doubling plying enters yarn-guide tube through ceramic ring, ceramic ring from sleeve pipe passes, be wound up on the bobbin of cylinder (groove drum) frictional drive through yarn-guide mouth (or directly through groove drum groove), adjust the driver of servomotor, make its winding speed can satisfy the twist design requirement.
The 1 rings steel traveler because of the speed-raising of restriction spindle is cancelled, and makes the spindle speed-raising become possibility; And output is enhanced about more than once under the equal rotating speed; Direct Spinning is made a yarn, and having reduced doffs stops platform, has increased output efficiency.Therefore output will significantly improve, for the 3-4 of traditional ring spinning yarn doubly.
2 because of when spinning air ring in the enclosed environment yarn-guide tube, spinning tension disappears substantially, spinning broken end phenomenon drops to minimum.
3 have cancelled rings, steel traveler, reduce steel traveler friction to yarn when rotating at a high speed, and product quality is improved; Flyings are reduced, and workshop condition takes a turn for the better, and quality is taken a turn for the better.
4 because of a spindle load has sleeve pipe and yarn-guide tube, and load reduces; Spindle whenever turns around and adds two twists, and output doubles; Winding mechanism in traditional ring throstle and the winding procedure in the spinning technological process have been cancelled: its power consumption is reduced significantly.
5 in sum, and workman's amount of labour reduces significantly, and recruitment reduces in a large number, the 1/5-1/10 (being spun kind and equipment difference) of ten thousand ingot recruitments spun yarn winder two-step during only by existing ring spinning, and as by specific yield calculating per capita, recruitment will be lower.
6 when doubling twisting, compares with existing two-for-one twister, has cancelled the doubling operation, does not need to change the yarn joint midway, and its application magnetic suspension principle, has both reduced energy consumption, has reduced workman's amount of labour again, has reduced recruitment; Compare with traditional twisting machine, advantages such as output efficiency, power consumption, recruitment will be more obvious.
