Description
Technical field
The present invention relates to a kind of device that is used to produce charging yarn (Scheinzwirnes), this device is equipped with a drafter, and being used for provides two fiber strips of motion drawing-off side by side for the compressional zone on output jaw line.The terminal of compressional zone is a feeding jaw line that causes twisting stopping, and is positioned at the place that segment distance interval is arranged with output jaw line, and feeding jaw line is a twisting mechanism that is used for twisting the fiber strip that has compressed at the back.
Background technology
Charging yarn is with the real difference of twisting thread: the twist direction that is used to produce the component of charging yarn is consistent with the twist direction of the charging yarn that processes.And for real twisting thread, forming the component of twisting thread is different with the twist direction of twisting thread that processes.The manufacture process of charging yarn is such: on spinning position with two fiber strips or roving-drafting, in the later operation of drawing-off before twisting apparatus with two fiber strips and together, and together twisting.
The spinning twisting if said components will begin in a minute behind the output jaw line of drafter, this device just exposes its shortcoming, and promptly each component the spinning triangle with relative broad basal plane (Basis) can occur on output jaw line.This is on output jaw line, to have relatively large width because be used for forming the drawn fiber yarn of the component of charging yarn, and the spinning of introducing twisting can form less diameter.Have the edge fiber on the spinning triangle of wide basal plane, it does not have any effect not quite in other words to the intensity effect of the yarn produced.People's effort dwindles as much as possible the basal plane of spinning triangle through the fiber strip of bunchy or side compression drawing-off.Should avoid in twisting, not having the edge fiber of regular bunchy (einbinden) thus to a great extent.
One produce charging yarn, have and place the said types of devices of beginning of the compressional zone after the drafter known by prior art DE 102 18 794 A1.The fiber strip of two drawing-offs is pneumatic in this compressional zone that passes through, and produces the air-flow to the fiber strip effect from the side, and the collection (Zusammenfassen) that air communication is crossed the edge fiber comes the conpressed fibers yarn.Because negative pressure is essential, so the energy input of having relatively high expectations in the compressional zone of pneumatic action.
Summary of the invention
Task of the present invention provides a kind of device of producing charging yarn, and its compressional zone is without any need for negative pressure.
This task solves through a kind of device that is used to produce a kind of charging yarn; This device has a drafter; It is that a compressional zone provides two fiber strips of motion drawing-off side by side that this drafter is used on an output jaw line; The terminal of this compressional zone is a feeding jaw line that causes twisting stopping, and this feeding jaw line is spaced apart with output jaw line, and this feeding jaw line is a twisting mechanism that is used for carrying out for the fiber strip that had compressed co-twisted at the back.According to the present invention, have a mechanical compressor reducer on the compressional zone, have on it two that settle side by side, along the pressure channel that the fiber strip throughput direction narrows down, this pressure channel is closer to each other along throughput direction.
Although it is known by prior art WO 03/,095 723 A1 to be connected to the mechanical type compressor reducer of drafter, the there face does not have the device of known any production charging yarn.
These two pressure channels can preferably respectively have the bearing-surface that corresponding fiber strip is turned to of a bending.This bearing-surface can be made up of the spigot surface that moves along corresponding fiber strip throughput direction.Spigot surface for example can be considered the circumference of the delivery roller on the correspondence output jaw line of drafter.Spigot surface can be compressed the form covering of device with passage.Delivery roller can be except that output jaw line, also directly corresponding to feeding jaw line.
The particularly advantageous structure of the present invention is that pressure channel is closer to each other along throughput direction.The advantage of this design is, the fiber strip after two drawing-offs and the compression just can merge in the very short distance behind feeding jaw line becomes charging yarn.
Description of drawings
Description through following embodiment can further embody other advantage of the present invention and characteristic.
Show among the figure:
Fig. 1 is the partial cross-sectional side-elevation view at the place, compressional zone of device of the present invention,
Fig. 2 is with respect to the enlarged drawing of Fig. 1, and promptly the direction of arrow II is seen and the view of compressional zone in the past do not comprised corresponding roller in Fig. 1,
The profile of Fig. 3 III-III line that is the compressional zone in the figure two.
According to Fig. 1 to 3, the building block that is used to produce the device 1 of charging yarn comprises a drafter 2, and a compressional zone 3 and coupled twisting mechanism 4 are arranged thereafter.
Drafter 2 has only been depicted delivery roller basically to 5 and 6, and it is made up of the bottom roll of being with driving 5 and pressure resilient top roller 6 above that.As everyone knows, the belt lace that is used for carrying two fibre bundles or rove 7 and 8 places before delivery roller 5 and 69 and 10 in known manner.Fiber strip that is running parallel or rove 7 and 8 along throughput direction A in drafter 2 drawing-off until the fineness of needs.The draw zone of drafter 2 ends at delivery roller on 5 and 6 the output jaw line 11.
Behind output jaw line 11, have two drawing-offs but also not have the fiber strip 12 and 13 of twisting, they will should compress according to above-mentioned principle in ensuing compressional zone 3.At outlet side, compressional zone 3 is by 14 restrictions of feeding jaw line.Structure feeding jaw line 14 makes twisting stop roller 15, is spaced a distance with output jaw line 11, is pressed on the bottom roll 5.
Article two, the fiber strip 16 that compressed and 17 comes out from compressional zone 3, is transported in the ring ingot 19 to B is called as twizzle through one air ring thread-carrier 18 along the supplier.Through ring ingot 19 these two fiber strips 16 and 17 through overcompression are twisted together; On the fiber strip 16 and 17 of compression, produce spinning twisting, and merge the charging yarn 1 that the back produces the identical twist direction twisting in edge at merging position 20 place's fiber strips 16 and 17.
Compressional zone 3 between output jaw line 11 and feeding jaw line 14 contains a mechanical type compressor reducer 21, and two pressure channels that are installed with side by side 22 and 23 are arranged on it.Pressure channel 22 and 23 narrows down along throughput direction A simultaneously.At first as shown in Figure 2, pressure channel 22 and 23 madial wall 24 and 25 move closer to each other, are used for fiber strip 12 and 13 side direction bunchy in its course of conveying.Cross section as shown in Figure 3 on the other hand constitutes V-arrangement with pressure channel 22 and 23 at least in the scope of feeding jaw line 14, the bunchy effect is perpendicular to side 24 and 25 thus.
As shown in the figure, the circumference of the bottom roll 5 that compressor reducer 21 will drive along twist direction C with its pressure channel 22 and 23 has covered with the form of passage.Madial wall 24 and 25 can be placed on the circumference of bottom roll 5 smoothly.And in the same way for each fiber strip 12 and 13, the bearing-surface 26 that forms motion and bending turns to fiber strip 12 and 13.No matter be that compressor reducer 21 or top roller 6 stops roller 15 with twisting and all be placed on the bottom roll 5.Reasonability is that the diameter of bottom roll 5 is bigger with the diameter that twisting stops roller 15 than top roller 6 thus.
Can find out obviously that from Fig. 2 pressure channel 22 and 23 close to each other along throughput direction A is till distance each other is relatively shorter.This spacing is as much as possible little, and its size makes the fiber strip 16 and 17 after the compression just can be separately just passable on feeding jaw line 14.Be compressed in compressional zone 3 through fiber strip 12 and 13, fluffing has tailed off, so that above-mentioned spacing needs only several millimeter is just much of that.This has very big advantage, promptly just can be very little with the distance between the feeding jaw line 14 with the merging position between the charging yarn 1 20 at the fiber strip that compressed 16 and 17.Can obviously improve the stability of spinning like this, reduce the risk of yarn breakage.
