Description
Technical field
The present invention relates to a device that is used for compressing fiber assembly on a fine spining machine, this device has a pair of output drawing rollers that are positioned at a drafting system to compacting zone afterwards; Have one and transport the conveyer belt of the gas permeability of a fibre bundle through compacting zone thus; Has a suction channel that is arranged in this compacting zone; Have one be arranged on the suction channel, the guiding sliding surface conveyer belt, that be reinforced; Has a suction slit that is arranged in this sliding surface; And have one and on the jaw of the end in this suction slit, this fiber strip is pressed on the conveyer belt and this conveyer belt is pressed on gripping roller on the sliding surface.
Background technology
If the delivery roller that the fiber strip of drawing-off is directly connected to drafting system on twist, on the right jaw line of this delivery roller a so-called spinning triangle will appear then.This is because the fiber strip of drawing-off leaves drafting system with a fixing width, and co-twisted becomes a yarn that diameter is less.The spinning triangle has abandoned not enrolling in accordance with regulations the edge fiber in twist yarn, therefore seldom or at all is helpless to the intensity of institute's spun yarn.Therefore recently people transfer to and are provided with one are rolled the so-called compacting zone that a little is limited in outlet side by one behind the draw zone of drafting system, have only after this and could twist yarn.Fiber in compacting zone by boundling or compacting, thereby make fiber strip when leaving last roll, become very thin, and the spinning triangle worried no longer takes place.So the yarn that is spinned will be more all even solid, and fine hair seldom.
In DE199 03 113 A1, a kind of this paper starts the device that is used for compressing fiber assembly of described type and has represented this prior art.In this device, the sliding surface of suction channel is made of a thin metal film, and this metal film has a window formula gap that is suitable for the profile in this suction slit, and this gap is slightly less than the suction slit.This metal film can be designed to have the open type strip of two joints, and they are positioned at outside the sliding surface.The width of this metal film is corresponding to the width of conveyer belt.
The a plurality of spinning of this known suction channel extend past position and in each spinning position, all comprise a described thin metal film.These metal films are because wearing and tearing, must be constantly can be with new replacement.When in known device, changing a metal film, this suction channel must be taken off from machine, in view of the above, before a metal film to be replaced can be reinstalled, the whole metal film that is installed on the suction channel must be removed by the promotion of side direction.This replacing is time-consuming and trouble.
Summary of the invention
Task of the present invention is, finishes the reinforcing that this paper is started the suction channel of described class device, and this reinforcing is limited in the frayed position of sliding surface and can changes easily.
This task can solve like this, promptly partly form sliding surface by a appearance profile with the parts of the concordant extension of outer surface of this suction channel, these parts are embedded in the suction channel, and it is replaceable, these parts will aspirate that the slit is whole to surround, and the whole working width of extend past jaw on the jaw position at least.
Therefore these parts according to the present invention are formed is not the sliding surface of whole suction channel, and only is this position of being worn and torn especially.For this reason, the appearance profile of these parts evenly is provided with respect to all the other outer surfaces of suction channel.Because the wearing and tearing of suction channel are gripping the jaw location maximum of roller, so these parts working width of the whole gripping roller of extend past on this position at least.The wearing and tearing danger at all the other positions of sliding surface is less, so these parts can be narrower in case of necessity.Therefore the suction slit that surrounds outside the jaw is just enough with needing only this component framework formula.
Because the conveyer belt of this gas permeability is designed to around the running of this suction channel, so certain steering position is arranged, therefore, especially this is a narrow especially guider that turns at the output drawing rollers of drafting system to the steering position on the position.Do for this reason so to arrange: what the appearance profile that these parts belong to sliding surface surrounded suction channel is positioned at the output drawing rollers to the guider that turns on the position.
Because the compacting of fiber strip is subjected to the promotion of suction air, so produce fibre fluff simultaneously, these fibre fluffs partly are excluded by suction slit and suction channel.Demonstrate, when these parts by slotted eye with the air inlet slit during to the inner lengthening of suction channel, effective especially for the eliminating of fibre fluff.Than turning to the guiding device position manyly outstanding, this is because rule of thumb to this slotted eye at the jaw position, and fibre fluff occurs more frequently in the end in suction slit than the original position in the suction slit.
This transport tape that is driven from the outside by the gripping roller should rub on the sliding surface of suction channel or these parts and slide lessly.Therefore do so to arrange: the appearance profile of these parts is provided with one and reduces the structure that rubs between these parts and the conveyer belt.Can be for example a kind of minute groove line, a kind of reticulate pattern or a kind of orange peel shape surface texture of the direction of motion along conveyer belt herein.
Description of drawings
Other advantage of the present invention and feature can be known from the explanation of an embodiment described below.Accompanying drawing is depicted as:
Shown in Figure 1 is by a partial cut away side views according to device of the present invention.
The direction that shown in Figure 2 is along arrow II among Fig. 1, the view of seeing from the position of these parts.
The specific embodiment
According to Fig. 1 and Fig. 2, the device 1 that is used for compacting fiber strand 2 is the member of a fine spining machine, is preferably the member of a ring spinner.Each spinning position of this fine spining machine has an only drafting system 3 shown in the part, here this drafting system only show a pair of output drawing rollers to 4 and a pair of preposition apron to 5,6.
These output drawing rollers comprise a bottom roll 7 to 4, and its structure is along the fluted roll machine longitudinal extension, driven, and are provided with a drawing-off top roller 8 in each spinning position.Bottom roll 7 and drawing-off top roller 8 form output jaw line 9 mutually, and it stops the front draft zone of drafting system 3.
Article one, ribbon or a rove 10 are fed to drafting system 3 along throughput direction A, and are drawing to desired fineness in known manner in drafting system 3.The output drawing rollers that compacting zone 11 is positioned at drafting system 3 are to after 4, and this is drafted in this compacting zone 11, still untwisted fiber strip 2 should or be compacted by boundling.This device that for this reason exists 1 comprises the conveyer belt 12 of a gas permeability, and it carries fiber strip 2 through compacting zone 11.The structure of conveyer belt 12 is preferably the webbing of the thin detailed catalogue that is made into polyamide yarn.
The outlet side end of compacting zone 11 is by jaw 13 restrictions, and this jaw 13 plays the resistance twist device simultaneously, and fiber strip 2 keeps non-twist state in compacting zone 11 like this.Form yarn 14 in the junction with jaw 13, it is directed to a unshowned twisting apparatus along outbound course B, and for example one is encircled ingot, and obtains its spinning twisting here.
This device 1 also comprises a suction channel 15, and this suction channel preferably is made of a section tube that is under the negative pressure.Suction channel 15 preferably extends across a plurality of spinning position, and all is connected on the low pressure source of not drawing by a negative pressure tube connector 16 in each machine part.
The lateral surface in the face of conveyer belt 12 of this suction channel 15 is designed to sliding surface 17, and this sliding surface guides conveyer belt 12 in this scope.
Be furnished with a suction slit 18 of extending generally along throughput direction A in sliding surface 17, it is transferred is with 12 coverings, and approximately extends to jaw 13 places.As shown in Figure 2, suction slit 18 is arranged obliquely with respect to the direction of motion of conveyer belt 12.
In order to realize that at jaw 13 places necessary twisting stops, being furnished with one and gripping roller 19, this grips roller 19 driving conveyer belts 12 and fiber strip 2 is pressed on the conveyer belt 12, and with certain pressure conveyer belt 12 is pressed to sliding surface 17.Grip roller 19 itself and obtain driving by the drawing-off top roller 8 of drafting system 3 it by a flat-toothed belt 20.
Wearing and tearing for sliding surface 17 pressure arranged owing to grip roller 19,, form certain wearing and tearing, so should be eliminated especially at the position of jaw 13.Be furnished with removable parts 21 for this reason, it will be described in detail hereinafter.Though these parts are designed to be more wear-resisting, for example constitute by wear-resisting relatively plastics, also should be designed to the wear-out part that a moment can change.
As shown in Figure 1, the outer surface 22 of suction channel 15 has a big relatively radius.But this radius is impossible at the output drawing rollers to the position of 4 preceding jaw line 9, turns to guider 24 because be furnished with one there, and it has an especially little radius.Because jaw line 9 places before suction slit 18 should closely be directed to are so this is necessary as far as possible.Because turn to guider 24, so the appearance profile that belongs to sliding surface 17 23 of parts 21 surrounds the guider 24 of turning to of suction channel 15 to enter on to 4 position at the output drawing rollers also owing to the less reason of radius is easily frayed.
When a fibre bundle 2 is provided the suction air, always produce fibre fluff.This can directly get rid of by suction slit 18 usually.In order to get rid of fibre fluff especially effectively, parts 21 so design: will aspirate slit 18 by a slotted eye 25 and extend in suction channel 15.So as seen, sliding surface 17 is less polluted by fibre fluff.
Pass through friction-driven conveyer belt 12 from the outside because grip roller 19, so must guarantee a good frictional drive at this.On the other hand because conveyer belt 12 slippage on sliding surface 17 is so should reduce the friction of sliding surface 17 as far as possible.This also is specially adapted to the appearance profile 23 of parts 21.Do for this reason so to arrange: the appearance profile 23 of parts 21 has a structure 26 that reduces friction between these parts 21 and the conveyer belt 12.The notion of " structure " hereto can be for example a kind of minute groove line, a kind of reticulate pattern or a kind of orange peel shape structure of the direction of motion along conveyer belt 12.
