Technical field
The present invention relates to a kind of ring throstle, specifically relate to ring throstle drafting system fibre strand integrated composite compacting apparatus.
Background technology
In traditional spinning unit, when the back area draft of fiber strip process ring throstle drafting system and proparea drawing-off arrive the front roller nip place, the output fiber strip is to there being a spinning triangular zone that does not have turn between the twisting point of twisting into spun yarn, because fiber is in runaway condition substantially in this trigonum, particularly the fiber at edge, trigonum can not be gathered and be twisted with the fingers in the fibre bundle, very easily break away from and stretch out this zone and become flyings and filoplume, each position tension force that fiber bears of this trigonum is also inconsistent in addition, the final powerful index that influences the spun yarn resultant yarn, therefore, the existence of spinning triangular zone is the key factor that seriously restricts yarn row yielding and yarn quality.
In order to eliminate the negative effect of spinning triangular zone, the compact zone that gathers of a fiber strip has appearred being provided with before drafting system output jaw, fiber strip have only through this fibre dense district gathered with closely knit after, could twist yarn, thereby eliminated the spinning triangular zone that people worried, so it is more all even solid that the yarn that is spinned becomes, and filoplume seldom.
At present, this to fiber strip gather with closely knit device in, type of drive to conveyer belt all adopts friction-driven, it is front roller frictional drive anterior epithelium cornea roller, the anterior epithelium cornea roller drives by gear drive and gathers roller, gather roller and be placed in conveyer belt on the aspiration channel by frictional drive again, have the two-stage friction transmission on the one hand in this device, transmission of power is just unreliable; More outstanding one side is, because gathering roller can not provide enough big thrust, otherwise both made structure complicated, may form new spinning triangular zone again, thereby can not provide enough frictional power to conveyer belt, such as the influence of factors such as vibration equipment, the conveyor belt surface linear velocity is difficult to keep stable and coupling with the output speed of front roller nip in addition, thereby very easily form irregular misdraft, directly influence the yarn quality index fiber strip.
Summary of the invention
Be difficult to guarantee jaw output speed and the mutually unstable deficiency of conveyer belt linear velocity in order to overcome existing fiber gathering device, the invention provides a kind of ring throstle fiber gathering device, this apparatus for collecting can not only be avoided spinning triangular zone effectively, and can keep the balanced mutually coupling of front roller nip output speed and conveyer belt linear velocity.
The technical solution adopted for the present invention to solve the technical problems is: the ring throstle fiber gathering device, it comprises front roller, anterior epithelium cornea roller, gathers roller and is arranged at the aspiration channel that gathers the roller below, have the air draught groove on this aspiration channel, conveyer belt is socketed on described aspiration channel and the middle live-roller, live-roller in the middle of front roller drives by the band transmission, and power is transferred to conveyer belt.
After adopting said structure, because conveyer belt is socketed on the aspiration channel of band air draught groove slidably, fibre bundle one in the spinning process leaves front roller gripping jaw and promptly enters on the conveyer belt, and be subjected to the control and the compression of negative pressure trough negative-pressure air-flow, fiber strip is gathered and closely knit, thereby avoided spinning triangular zone.More because conveyer belt provides frictional power by front roller rather than by gathering roller, this structure makes conveyer belt and gathering in the frictional drive of roller, and conveyer belt has become driving link, and gathering roller becomes driven member; The linear resonance surface velocity of conveyer belt is no longer gathered the influence of roller thrust size, also be no longer dependent on itself and the frictional force size of gathering roller, and directly depend on front roller, thereby guaranteed the stable mutually and coupling of front roller nip output speed and conveyer belt transporting velocity effectively, yarn quality is better.
