Description
Technical field
The present invention is about a kind of reel cage with polishing voltage regulation function, especially a kind of have be wholely set with the reel cage rigidity, possess many grades of pressurization functions independently voluntarily pressing mechanism with the spinning machine reel cage of effective elimination resultant yarn twist triangle zone yarn.
Background technology
In spinning process, sliver is clamped sliver by a kind of pressue device (being reel cage) usually and is carried out drawing-off, with the spinning resultant yarn.Through the rove that forms after the reel cage drawing-off,, at this moment form the zone and will form so-called spinning triangular zone at yarn owing to exist than big-difference between the resultant yarn width of the yarn width of drawing-off and twisting back sliver.Because the spinning triangular zone loose fibres can not be well controlled, many fibers around the fibre bundle can be scattered in advance or can not be controlled fully.Thereby, the fiber of spinning triangular zone edge yarn, when twisting usually can not be twisted with the fingers in the yarn and become that flyings lose or since seldom bag advance in the yarn, make the fiber of many edges and bottom stretch out yarn and promptly form filoplume outward.Simultaneously, because the heterotonia of each fiber in the spinning triangular zone in twisting process, in the yarn fiber alignment stretch inadequately, parallel, tight, cause resultant yarn when bearing pulling force, the brute force of yarn is lower than the summation of each root fiber bearing capacity on the yarn cross section, and makes that the integral body that can reduce resultant yarn is powerful.
Therefore, all there is very big deficiency in the yarn quality of traditional spinning machine as indexs such as filoplume, brute force, bar evenness and fiber losses.For traditional spinning technique is significantly improved on yarn quality, just must improve the conveying form of fiber before the twisting, promptly reduce before the twisting or eliminate twist triangle zone, make fiber parallel, stretch and as far as possible closely arrangement mutually.For this reason, the method that adopts is to install collector in drafting unit additional usually, the resultant yarn filoplume situation is improved, but its resultant yarn bar evenness has been subjected to bad influence.
Related art such as Chinese invention patent ZL00135183.4 and Chinese invention patent application CN03116466.8, CN021124468.X etc., fibre strand integrated composite device is all adopted in these three patents and patent application, to eliminate the filoplume phenomenon that produces at the yarn twist triangle zone in the spinning process as far as possible.Wherein, the disclosed fibre strand integrated composite device for ring spindle spinning of ZL00135183.4, comprise by the gather roll axis deck of M shape spring steel wire, band groove, M shape spring carrier that band triangle pressure block is formed with by a pair and gather the roller that gathers that roller, gather roll axis, abutment sleeve form.This pair of gathering roller is gathered and is had splitting guide groove on the roller and gather groove, can reduce the twist triangle zone that produces Yarn filoplume to a certain extent.
Application for a patent for invention CN03116466.8 then provides a kind of Lear Ring Air Groove Poly Fiber Strand Collection Device.It comprises that front leather roller, front roller, reel cage, negative-pressure air fan, negative pressure suction tube, additional with groove bottom roll, a secondary light quality apron roller and light quality apron roller shaft, U-shaped support, subband hole apron Xiao, a subband gather the apron of groove and eyelet.The apron that gathers groove and eyelet at this device overdraught by band, under the guiding of air-flow, fiber strip polymerization and close mode gradually in gathering groove, this gathers process and finishes on the apron surface, gather process and have the long distance and the time interval, the axially parallel degree of the fiber in the yarn is greatly improved for this reason, and the above hairiness number of yarn appearance 3mm is reduced significantly.
And the disclosed fiber strand aggregating device for air slide of another part application for a patent for invention CN02112468.X then is provided with a kind of new splitting guide groove and the groove that gathers of band pore.This gathers the preceding jaw that groove is located at the fine spining machine draw zone and exports between the spinning section, form a fiber jaw again with fiber strand aggregating device for air slide and front roller, gather air-flow by additional several strands of this device, provide a kind of flow field guiding groove and the fiber that gathers in the groove.The compartition of fiber strip is guided and gathers the guiding of air-flow in the groove via guiding groove, fiber strip is subjected to gathering of air-flow again in gathering groove, make fiber strip be able to tight twisting in the groove gathering, thereby make the fiber filoplume amount of yarn appearance obtain very big improvement, and yarn strength also is improved largely.
Similarly, Chinese utility model patent ZL02216530.4 also discloses a kind of compact spinning apparatus of fine spining machine.It is being set up with lower member on conventional drafting system basis: two ends are fixed on adjacent two roller stands and with the air intake duct of air-breathing skewed slot and exhaust outlet, air intake duct is with the thin-walled cylinder that circumferencial direction has aperture outward.Described cylinder two ends close-fitting has self-lubricating bearing, and cylinder can be turned round around air intake duct, is lined with the pad of concentrating negative pressure between cylinder and the air intake duct, and the pressurization roller of cylinder is by driving member and the interlock of front roller pressurization roller.Under the reel cage pressurized state, the pressurization roller of cylinder presses cylinder surface, drives the cylinder revolution.
Above prior art has a common starting point, promptly is to be conceived to reduce even the twist triangle zone of elimination on the resultant yarn of the preliminary spinning of reel cage as far as possible.The concrete technical scheme that is adopted also has a common ground, promptly is that certain device (normally increasing a roller that gathers usefulness) of design makes the yarn of resultant yarn twist triangle zone carry out gathering to a certain degree.Early stage design, as ZL00135183.4, its pair of gathering roller is gathered roller and is provided with splitting guide groove and gathers groove, to attempt to reach the purpose of the yarn that is reduced to the yarn twisting trigonum.The mentality of designing of main flow is to increase the roller that gathers with air-breathing function at present, as above-mentioned Chinese utility model patent ZL02216530.4, Chinese invention patent application CN03116466.8, CN021124468.X etc.
Yet, if only adopt the apparatus for collecting or the compact spinning apparatus of above-mentioned prior art, because preliminary resultant yarn is during via above-mentioned apparatus for collecting or compact spinning apparatus, though owing to gather the getter action of groove or corresponding suction hole, the yarn of resultant yarn twist triangle zone both sides and below can be twisted with the fingers in the yarn by being gathered to a certain extent or the resultant yarn twist triangle zone can be inhaled in the air intake duct by the yarn of below, thereby can reduce the filoplume phenomenon of resultant yarn.But the yarn of resultant yarn twist triangle zone top still can't be eliminated effectively.Therefore, just be necessary above the resultant yarn twist triangle zone, to be provided with certain device, gather the yarn of twist triangle zone top, with the filoplume phenomenon of further elimination resultant yarn.
The existing general practice is the conjunction of external plastics or other material on the front upper roller of reel cage, installs a polishing top-roller leather roller simultaneously additional, to be implemented on original reel cage drawing-off basis, reaches the polishing effect to resultant yarn unhairing plumage.
Chinese invention patent application CN03115186.8 has promptly disclosed a kind of like this compact spinning apparatus of ring throstle, comprises that drawing rollers are to, roller stand and reel cage pressue device.Be primarily characterized in that and be provided with also that two ends are fixed on adjacent two roller stands and the air intake duct of band position, inlet scoop, it is outer and have a cohesion cover of collection surface at the circumferencial direction corresponding to the position, inlet scoop to be enclosed within air intake duct, be stuck in the tensioning apparatus in the cohesion cover chute, be enclosed within the ventilative conveying circle on collection surface and the tensioning apparatus, and the ventilative transmission pressue device of carrying circle.This transmission pressue device is installed on the reel cage body fore paw, comprise gear frame, two backer rolls with two respectively with the coaxial synchronous pulley that is connected of aforementioned two backer rolls.Two pressurization rollers are fixed on the gear frame by pressing plate, and two synchronous pulleys drive backer roll by the synchronous band on it and rotate, and are rotated by the ventilative circle of carrying of one of them backer roll drive.
The transmission pressue device (being similar to above-mentioned polishing top-roller leather roller device) that above-mentioned patented technology adopts can solve aforementioned the deficiencies in the prior art to a certain extent.But, shortcoming is: transmission pressue device that adds or polishing top-roller leather roller device do not have stepped voltage regulation mechanism, be sandwiched in its backer roll and can only fix wearing, can't come to adjust flexibly this pressure as the case may be with the resultant yarn institute applied pressure between the corresponding polishing bottom roll (the similar roller that gathers).Thereby its effect of eliminating the resultant yarn filoplume phenomenon is also also very good.
In addition, because newly-increased polishing top roller is by being installed at the pressurization conjunction (gear frame etc.) in reel cage proparea, obtaining the pressurization of pressure source enforcement to the polishing bottom roll.Therefore, in pressure process, can produce tangible component to the reel cage proparea, thus the drawing-off pressure of influence spinning, the quality of reduction resultant yarn.And its polishing top roller backer roll is fixed on the gear frame (pressurization conjunction) by pressing plate, and synchronous pulley also is coaxial being connected on the backer roll simultaneously, makes its loading and unloading and adjustment get up very inconvenient.
