Abstract
A device for compressing a drafted assembly of fibers is arranged downstream from a pair of delivery rollers in the drafting equipment of a spinning machine. The compression area comprises a suction roller which lies adjacent to two driven rollers forming two clamping points for clamping the assembly of fibers. A suction slot is located inside the suction roller between the clamping points. Said slot defines the length of the compression area. The first clamping point in the direction of conveyance of the assembly of fibers is formed with a driven lower roller belonging to the pair of delivery rollers in the drafting equipment, whereby the assembly of fibers to be compressed is guided in a continuously effective manner from the drawing area to the end of the compressing area.
Description
The present invention relates to the device at fine spining machine upper set one one ribbon, it comprises a set district that is positioned at the front roller of drafting system to the downstream.There is a suction roller in this set district, and it is pasting on the roller of two velamens driving under the situation that forms two gripping fiber strip jaws, and suction roller inside has one to be positioned between two jaws and suction slot that determine the set section length.
Be in when directly being switched to the right ribbon of drafting system front roller when spinning twisting is assigned to, a so-called spinning triangle has just formed at the right jaw line place of front roller.Therefore, make the ribbon of the width in accordance with regulations of drawing-off leave drafting system and twist into a thinner yarn.The spinning triangle contains not according to the edge fiber that normally is incorporated in the twisted yarn, and they seldom or at all are helpless to the brute force of resultant yarn.Therefore, take transition method in recent years, a so-called set district promptly is set in the draw zone downstream of drafting system, the latter is subjected to the restriction of a jaw at outlet side.After jaw, give yarn with the spinning twist.Fiber is boundling or set in draw zone, and like this, ribbon has tapered to the degree that fearful spinning triangle can not be formed when leaving a back jaw.Relatively more even, the powerful higher and less filoplume of spun yarn.
The above-mentioned this device that has a set district can be learnt from the prior art of Fig. 2 of DE19815052A1.In this known devices, must be before the suction surface of roller of the ribbon of drawing-off under it arrives the set district through certain distance under unsupported situation.This need be drawing to its final fineness and as yet the ribbon of spinning twisting that yes is very easily broken, the danger that produces misdraft is arranged, even the danger of ribbon fracture.
Task of the present invention is to improve above-mentioned this device, thereby prevents the danger of misdraft and ribbon fracture.
So finish this task, promptly first jaw by the ribbon throughput direction is to constitute together with the right driven bottom roll of the front roller of drafting system.
On the basis of this technical scheme, drawing-off but still untwisted ribbon be attached to all the time on the outer peripheral face of a roller to terminal from draw zone terminal to set district.At first, this is the part of preceding bottom roll circumference, exactly is the part before first jaw, promptly at this place suction roller bottom roll that reclining.Then, the ribbon looping in set district exactly is before second jaw on the periphery of suction roller, and the spinning twisting behind the jaw is awarded the ribbon of having gathered.Like this, ribbon is being able to good guiding on the whole distance that might rupture.
By dependent claims and below an embodiment in obtained other advantage of the present invention and feature.
Fig. 1 cuts open side view according to the office of a device of the present invention;
Fig. 2 is the view according to the arrow II direction of Fig. 1.
Device shown in Fig. 1,2 is a fine spining machine, and it mainly is the part of a spinning spindle position of ring throstle.Device 3 is in the downstream of the drafting system 1 of a drawn fiber bar or rove 2, and purpose is to make drawing-off but still untwisted ribbon 4 is gathered by the avris cohesion of its fiber.
Under normal conditions, drafting system 1 comprises a pair of rear roller 5, a pair of apron roller 6 and a pair of front roller 7.The bottom roll 8 that the latter is driven by a velamen and pressurization roller 9 are formed.On drafting system 1, ribbon or rove 2 generally are drawing to desired fineness by throughput direction A.The draw zone of drafting system 1 ends at roller to 7 preceding jaw line 10 places.
In a collection area in drafting system 1 downstream, drawing-off but the ribbon 4 of spinning twisting before it obtains twisting afterwards, gathered.Set district 11 is subjected to first jaw 12 and is subjected to the restriction of second jaw 13 at outlet side at entrance side.When spinning twisting subsequently was endowed spun yarn 14 in the spinning, second jaw 13 played only sth. made by twisting effect, so that make spinning twisting not return set district 11.If spun yarn 14 is admitted to not shown twisting apparatus as on the ring ingot by throughput direction B, the triangle that then spins just can not form at second jaw, 13 places.
The device 3 of collecting ribbon has a suction roller 15, and its periphery is equipped with eyelet, and like this, the shell of suction roller 15 is breathed freely in certain workspace as everyone knows.Suction roller 15 does not hold in a not shown manner on a fixing air intake duct 16, also is mounted with an adjustable suction unit 17 on this air intake duct.Suction unit 17 has a suction slot 18, and it extends and determined the length in set district 11 basically by throughput direction A.See that from Fig. 2 the direction of motion that suction slot 18 is configured to aspirate relatively roller 15 peripheries is slight inclination, so, the ribbon 4 that should gather moves along the limit of suction slot 18 and obtain slight false twisting in aggregation process.
Suction roller 15 is not only reclining front roller to driven bottom roll 8 of 7, the bottom roll 19 that another velamen that also reclining drives, thus form two so-called jaws 12 and 13.Because bottom roll 8 and 19 is relative to each other aspect transmission, so they have identical peripheral speed.Bottom roll 8 and 19 has disposed elasticity clad 20 and 21 respectively, and this is because of the suction metal surface of roller 15 but suitable.
See that from Fig. 1 front roller its nearly 90 ° periphery to 7 bottom roll 8 by ribbon 4 loopings.Ribbon 4 not only is between the jaw 12 and 13 in set district 11, and jaw line 10 beginnings in the past, and it has been on the seating surface always.Therefore, after drawing-off, guide ribbon 4 best, till authorizing the twist always.
