Description
Technology neck city
The utility model relates to a kind of ring throstle, relates in particular to the improvement with the drafting system of ring spinner that gathers the tight fibers strip device.
Background technology
Drafting system is one of most important parts in the ring throstle, and rove or strip have only through drafting system, could be taken out long drawing-down equably to resultant yarn desired number.Therefore, the structural shape of drafting system is directly determining the quality of quality index such as the bar of finished product yarn is done, filoplume, brute force.
Three roller drafts before, during and after common drafting system of ring spinner mainly adopts, three rollers are divided into front draft zone and first break draft district with drafting system.During spinning, the rove of unwinding from the flyer bobbin, the rear roller jaw through guide horn mouth feeding back roller and rear roller are formed successively enters first break draft district and front draft zone, arrives front roller nip, exports the drawing-off yarn from front roller nip, through twisting into the finished product yarn.
Because the rove of feeding rear roller jaw has the twist, rove is subjected to the drafting tension effect during drawing-off, and outer layer fiber stretches trend and presses to its axle center, and makes the contact of rove fibre compact.Thereby when spinning the rear roller jaw must keep enough grasping forces, otherwise the drawing-off rove will skid at the rear roller jaw, it is irregular that the lighter is worsened the sliver long segment, weight person produces deviation of weight.Yet the increase of nipper pressure has increased the weight of the burden of rear roller with the back roller again, and destructions such as the concave of roller, be full of cracks cause the jaw grasping force to descend and the adhesive tape fiber after very easily causing, and cause to grip inefficacy.For this reason, guide horn mouth on the fine spining machine in fact all is contained on the slow reciprocating traverse bar at present, the feeding of rove is not to enter from position of rear roller jaw, but has certain scope of traversing, alleviate the damage of nipper pressure with this, prolong its service life back roller and rear roller.
The fiber strip that forms through drawing-off, when leaving the front draft jaw, again because there be one so-called " twist triangle zone " in front roller nip, at the stressed skewness of each fiber of this twist triangle zone, fiber takes place inside and outsidely to shift and be in runaway condition substantially, and single thread force, filoplume, the bar that finally influences yarn such as does at the yarn quality index.
Compact spinning technology at " twist triangle zone " has appearred for this reason, it is to install the suction channel that has suction slot before front roller nip additional, be wound with ventilative conveyer belt on the suction channel slidably, on ventilative conveyer belt, be equipped with and gather roller, during work, the fiber strip of drafting system output, through the conveyer belt of breathing freely gather closely knit after, export and twist from gathering the formed jaw that gathers of roller and suction channel, indexs such as the mechanical performance of resultant yarn and bar are done, filoplume are able to obvious improvement.But because the existence of rear roller rear positions feeding horn mouth traverse motion, and the suction slot in the compact spinning apparatus is positioned on the hard-wired suction tube; The traverse motion of ribbon, making ribbon arrive suction slot always is not a same position, this periodicity reciprocating motion causes the ribbon can not be fully by gripping that suction slot gathers, tight apparatus for collecting is greatly affected to the fiber aggregate effect, and the compact spinning technical advantage is difficult to be not fully exerted.
Chinese patent application (application number 01138544.8) discloses the device of a kind of drawing-off and collecting ribbon, it is that suction tube is connected on the transverse transmission mechanism with traversing gear synchronous operation, though this has solved traversing gear to gathering the periodicity influence of ribbon, but its structure is very complicated, and installation and use all very bother, thereby actually rare this series products in market.
Summary of the invention
In order to overcome the existing in prior technology deficiency, technical problem to be solved in the utility model is, provide a kind of ribbon that traverses can pass through suction slot exactly, yarn quality be not subjected to ribbon traverse the feeding influence and the device that is used for the set tight fibers bar on the fine spining machine simple in structure.
Technical solution of the present utility model is: a kind of device that is used for fine spining machine upper set tight fibers bar, it comprises the horn mouth that traverses that is positioned at drafting system rear roller jaw rear side, is positioned at the suction tube of drafting system front roller nip front side and gathers roller, this suction tube is provided with suction slot and is wound with ventilative conveyer belt, collector is equipped with in first break draft district at drafting system regularly, and this first break draft district is positioned between rear roller and the middle roller.
Further embodiment of the present utility model is that described collector is installed on the middle roller slide by the collector mounting rod.This collector is the open type collector.
Further embodiment of the present utility model is, describedly gathers roller and front leather roller all is installed on the roller support, at this roller support and be locked in that roof pressure has the pressing spring bar between the pressurization pole on the reel cage.
In the utility model, owing in the first break draft district between rear roller and middle roller collector is housed regularly, thus both guaranteed that bell-mouthed periodicity traversed, protected back roller effectively, prolonged the service life of back roller; Eliminated ribbon again up hill and dale and traversed feeding, made ribbon strengthen gathering of ribbon closely knit exactly through the suction slot of compacting means to the negative effect that compact spinning apparatus brings.Also owing between rear roller and middle roller, collector is housed, further strengthened contraction to the fiber strip width, both made overhanging filoplume fiber lodging, increased the tightness of ribbon again, resultant yarn filoplume is further reduced, bar is done and powerful index further improves, and has the closely knit effect of even more ideal fiber aggregate, has also reduced end breakage rate simultaneously effectively.Also since collector by mounting rod regularly clamping be installed on the middle roller slide, it is simple in structure, installs easy to manufacture, easy for operation.
In addition, collector adopts the open type structure, has not only made things convenient for the processing and manufacturing of collector, and more helps using operation, can very easily ribbon be introduced collector from opening part during operation.Also owing to roof pressure between roller support and pressurization pole has the pressing spring bar, gather the normal pressure of roller on suction tube thereby stably increased, not only improved the frictional power of gathering between roller and the ventilative conveyer belt that pulls, and guaranteed to gather roller gathering the control action of fibre bundle.
