Description
Technical field
The present invention relates to the submissive bright and clean spinning apparatus of the spacing centralization type of a kind of groove, belong to technical field of textile processing.
Technical background
Filoplume is one of important indicator weighing yarn qualities.Yarn filoplume not only affects the production efficiency of the rear operation such as woven, knitting, and affects the presentation quality of final products, particularly high speed shuttleless loom today of generally applying, reduces Yarn filoplume tool and is of great significance.Because filoplume results from spinning process, so reducing fuzzy yarn is reduce basis and the key of filoplume.
Yarn filoplume results from the spun yarn manufacturing procedure of ring spinning.The spinning process key issue of common ring ingot spinning is: fiber strip pressure holding is flat belt-like by front roller nip, under the effect of twisting twisting resistance, there is inside and outside transfer in the fiber in flat belt-like fiber strip, when fiber a part has entered yarn body by inside and outside transfer, after now this fiber exposes the head portion disengaging front roller nip gripping effect of yarn body, cannot again enter or looping on yarn body trunk, so formed filoplume.China Intellectual Property Office's on 07 11st, 2007 invention disclosed patents " a kind of flatiron spinning method improving yarn property ", the patent No. 200610166509.9; Department of Intellectual Property of the U.S. discloses patent of invention " Methodandapparatusforproducinghighqualityyarnonaring-spi nningmachine ", patent publication No. 7552580B2 on June 30th, 2009.These two application complicated legal cases together provide a kind of flatiron spinning method that can heat to improve to fiber in spinning triangular zone yarn quality; Specifically, there is provided a kind of submissive bright and clean spinning apparatus carrying out pressing process to the fiber in the fiber in institute's yarn particularly twist triangle zone, can Yarn filoplume be greatly reduced, reduce spun yarn moment of torsion, improve yarn qualities.Be at present no matter side-mounted, underneath type or the submissive bright and clean spinning apparatus of overhead, common feature only adopts the flatiron work of single ironing apparatus to process in the face of sliver.Due in spinning process, spinning section sliver not only produces air ring and rocks, and sliver constantly changes height and angle with twizzle lifting, make sliver in the soft clean spinning process of whole flatiron formula, contact not tight, unanimously uneven with the flatiron working face of ironing apparatus, cause spun yarn fineness coefficient of variation large, product quality uniformity is poor.And the flatiron work of single ironing apparatus processes in the face of sliver, the winding tightness reducing Yarn filoplume is inadequate, easily rebounds in a large number in follow-up winding procedure process, can not meet high bright yarn Production requirement veritably.
Summary of the invention
For above-mentioned existing problems, the object of the present invention is to provide the submissive bright and clean spinning apparatus of the spacing centralization type of a kind of groove, to achieve these goals, technical solution of the present invention is:
The submissive bright and clean spinning apparatus of a kind of spacing centralization type of groove, comprise by heater block, adiabatic protecting cover, linking arm, the submissive bright and clean spinning apparatus of pedestal composition, arrange first on the top of submissive bright and clean spinning apparatus support arm and spacingly gather bar, first spacing to gather bar parallel with the flatiron working face of heater block, the first spacing periphery gathering bar has and spacingly gathers groove perpendicular to first of its axis, first spacing to gather groove bottom land center corresponding with the flatiron working face center of heater block, and first spacing gather groove bottom land and the flatiron working face of heater block tangent, in the bottom of submissive bright and clean spinning apparatus support arm, contiguous block is set, contiguous block is arranged second and spacingly gather bar, second spacingly gathers bar and first spacing to gather bar parallel, the second spacing periphery gathering bar has and spacingly gathers groove perpendicular to second of its axis, second spacing groove bottom land and the first spacing groove bottom land that gathers of gathering is in same plane, first spacingly gathers bar, second spacing to gather bar parallel with the pedestal of submissive bright and clean spinning apparatus.
The first spacing groove width gathering groove is 0.6-2 millimeter, and the first spacing groove depth gathering groove is more than or equal to 1.5 millimeters.
The second spacing groove width gathering groove is 0.6-2 millimeter, and the second spacing groove depth gathering groove is more than or equal to 1.5 millimeters.
Owing to have employed above technical scheme, compared with prior art, the submissive bright and clean spinning apparatus of the spacing centralization type of groove of the present invention, its advantage is: the present invention adopts and to arrange first on the top of submissive bright and clean spinning apparatus support arm and spacingly gather bar, the first spacing periphery gathering bar has the first spacing structural design gathering groove perpendicular to its axis, carry out spacing to spinning section sliver, ensure that sliver is located at the flatiron working face near center location operation of heater block all the time, avoid in ring spinning process because traversing technique causes sliver to depart from flatiron working face, cause Yarn break and yarn quality difference, solve the problem that the yarn quality difference of original device production is large, first spacing the first spacing groove that gathers gathered on bar not only carries out gathering looping process in advance in time to the fiber after heating softening simultaneously, significantly improve filoplume and be wound around tightness, and to the sliver vibration effectively controlled in big or middle yarn spinning process, ensure the flatiron working face of heater block when sliver is close to all the time, make its abundant softening looping.Adopt and contiguous block is set in the bottom of submissive bright and clean spinning apparatus support arm, contiguous block is arranged second and spacingly gather bar, the second spacing periphery gathering bar has the second spacing structural design gathering groove perpendicular to its axis, not only gather looping process to carrying out tight type thoroughly through the first spacing sliver surface hairiness gathering groove, the further filoplume that improves is wound around tightness, and to the sliver vibration effectively controlled in little middle yarn spinning process, ensure the flatiron working face of heater block when sliver is close to all the time, make its abundant softening looping, significantly promote submissive bright yarn quality, not only eliminate original device large at spinning, in, there is larger difference sex chromosome mosaicism in the yarn quality occurred during little yarn, and it is inadequate from more originally solving the winding tightness of original device to Yarn filoplume, the technical barrier that filoplume easily rebounds.The present invention is rational in infrastructure, easy to operate, is easy to spread and uses.
