This conveyer belt having an air permeable lattice-shaped region including thermoplastic filaments is provided by crossing warp yarns and weft yarns for overlapping, then performing a heating/melting treatment for melt-bonding the crossing points of both yarns each other and fixing to form a nonwoven fabric sheet in which the lattice-shaped region is formed with the warp yarns and weft yarns, and using the same as the conveyer belt.
Description
Technical field
The present invention relates to a kind of conveyer belt that is used to carry a fiber strip that will condense with air-flow, this conveyer belt has a latticed position of breathable that contains thermoplastic filament.
Background technology
When one the fiber strip of the drawing-off front roller that on a spinning machine, is next to a drafting system then form a so-called spinning triangular zone when locating to obtain a turn at the right jaw line place of front roller.Here make therefore that the drawn fiber yarn with a Rack leaves drafting system, and make it twist into the yarn of thin diameter.Described spinning triangular zone contains unordered edge fiber of entwining in the yarn of having twisted, thereby seldom or fully is helpless to the intensity of resultant yarn.Therefore in recent years, people more and more tend to replenish so-called condensation region of layout to the draw zone of drafting system, and this is boundary in outlet side by a jaw line for this condensation region.Yarn just obtains twisting after this boundary.Fiber is in condensation region boundling or cohesion, and fiber strip becomes very thin when leaving last jaw like this, makes fearful spinning triangular-defects no longer seem important.Institute's resultant yarn seems that evenly, intensity is better and pile is few.
The different device that condenses an one fiber strand is that everybody is known.Many described devices carry out work with a ventilative conveyer belt, this conveyer belt make will aggegation fiber strip carry slidably by a suction slot.A kind of like this device is for example open in DE 198 37 182 A1.Having described conveyer belt in the document in addition can be made by a kind of fabric that contains thermoplastic filament.Thicker and thinner in case of necessity here long filament can be interweaved.The conveyer belt side seamed edge that is made into can be in case of necessity by the cutting tool cutting of a heating, to improve the hardness of seamed edge.
Here it should be noted that, in " air-flow cohesion " concept term of this patent application, also should comprise this device, wherein except the effect of playing inspiratory flow mechanism, also can play the effect of another kind of mechanism simultaneously, such as being used as a conveying assembly of tiltedly locating suction slot facing to one.
Summary of the invention
Task of the present invention is, creates a kind of novel conveyer belt in order to condense an one fiber strand with air-flow, and with prior art, this conveyer belt is that people do not know so far.
The throughput direction that the described long filament of the representation of concept of " organizine " is pressed fiber strip extends.Correspondingly " tram " extends transverse to the fiber strip traffic direction that transports.
A kind of breathable conveyer belt that produces by means of the present invention contains thermoplastic filament, and organizine and tram are such like an elephant having in the fabric, but they are not interweaved.Do not have genuine fabric structure, but form ventilative grid.This is the combination because mutually stacked up and down organizine and the tram heating process by thermoplastic filament interfixes, but should keep the desired gas permeability of conveyer belt.Should be noted also that and use a conveyer belt of producing like this between conveyer belt and one are disposed at the transmission roller of this conveyer belt, to have contact preferably.
Although the basic design of invention is, the thermoplastic filament that organizine and tram can application standards, such as polyamide filament, preferred version of the present invention is, and organizine and/or tram are made by the multicomponent long filament, and they have a fusible top layer.Described multicomponent long filament especially can be two composition long filaments.Be the top layer fusion during heating and latticed position fixed, and not fusion-or have a higher melt-sandwich layer guarantees the shape stability of conveyer belt.For example this pair of composition long filament can be made by two kinds of different aramid layers.
If tram is arranged on the side that is disposed at fiber strip, the attendant advantages that then obtains is, forms a kind of micro-textured on the side of the bearing fiber yarn of conveyer belt, improves the pull(ing) effect of conveyer belt like this by the transmission roller.Relevant details is illustrated below with reference to an enlarged drawing.
Conveyer belt is anlistatig in other scheme of the present invention.This for example can obtain by chemically treated antistatic finish, or uses anlistatig polyamide, this material to be included in the thermoplastic filament or add and advance in the described long filament.

Be positioned at a part figure who grips the roller position who uses as resistance twist among Fig. 1 of Fig. 5 approximate diagram 3 ratios, this gripping roller and grid-shaped position constitute a kind of miniature engagement;
The view of the similar Fig. 5 of Fig. 6 according to the conveyer belt of aforesaid prior art.
The specific embodiment
A spinning machine among Fig. 1 and 2, particularly ring throstle only express be used to condense one drawing-off, also do not have a position of a device 1 of the fiber strip 2 of twisting.Device 1 is right after after a drafting system 3, and drafting system has only been represented a pair of front roller 4 and a pair ofly be arranged in the apron roller 5 before this front roller along throughput direction A that this apron roller has a following apron 6 and a upper leather ring 7.Front roller comprises one by the preceding bottom roll 8 of transmission and a preceding pressure roller 9 that flexibly this preceding bottom roll is pressurizeed to 4.Front roller is to the 4 output jaw lines 10 that therefore define the terminal of the draw zone that constitutes drafting system 3.
In drafting system 3, an one fiber strand or rove 11 are drawing to the fineness of requirement in due form by throughput direction A.Described drawing-off stops at output jaw line 10 places, yet and lights also fiber strip 2 chargings of spinning twisting of described drawing-off from this.In order to dwindle known and harmful spinning triangular zone, fiber strip 2 is right after after output jaw line 10 and condenses in a condensation region 12.The device 1 that is provided with for cohesion comprises a ventilative conveyer belt 13, and the fiber strip 2 that this conveyer belt will be to be condensed is carried by condensation region 12.In addition, device 1 has an aspirating air pipe 14, and this pipe design becomes to be in the special-shaped hollow pipe in the low pressure, and many spinning spindle positions of extend past.Aspirating air pipe 14 is at its sliding surface 15 that is designed to guide conveyer belt 13 in appearance towards the condensation region.
Article one, suction slot 16 is arranged in sliding surface 15, and it is arranged for the moving direction slight slope ground of conveyer belt 13, thereby a side seamed edge of suction slot 16 is designed to fiber slide guide limit 17 about fiber strip to be condensed 2.Fiber strip 2 moves along this fiber slide guide limit 17 when coacervation process, be in fiber in the fiber strip like this transverse to the traffic direction boundling or the cohesion of conveyer belt 13, and fiber strip 2 is therefore curling slightly.Aspirating air pipe 14 is received the low pressure source of not representing among the figure by a low-pressure connection tube 18, and this low-pressure connection tube and suction slot 16 keep at interval.As long as aspirating air pipe 14 extends through many spinning spindle positions, then 14 need of every aspirating air pipe have a low-pressure connection tube 18.
The outlet side of condensation region 12 grips roller 19 by one and delimits, and this gripping roller is pressed onto fiber strip 2 and conveyer belt 13 on the sliding surface 15, determines output jaw line 20 simultaneously, and this jaw line plays the resistance twist effect for the twist that will obtain.Grip roller 19 and drive conveyer belt 13, and this gripping roller itself begins to be subjected to transmission by one such as 21 the past of the transfer wheel pressure roller 9 that is designed to gear.
The yarn 22 that forms after output jaw line 20 by described yarn being transported among the figure not the twisting mechanism of expression along outbound course B, encircling the twist that ingot obtains described yarn such as one.Aspect spinning twisting, jaw line 20 plays the resistance twist effect, and spinning twisting can not be stretched in the condensation region 12 to reaction like this.
As seen from Figure 2, the initial position 24 of suction slot 16 is widened, and its objective is to make slightly under any circumstance can be collected by suction slot 16 by the fiber strip 2 that laterally moves.Described laterally moving particularly can obtain the long life-span for preceding pressure roller 9.
Below with reference to the Fig. 3 to Fig. 6 that amplifies to installing 1 central component, being that novel ventilative conveyer belt 13 elaborates.
Can see the grid-shaped position 25 of conveyer belt 13 from the schematic diagram 3 that amplifies.Thermoplastic filament is as organizine 26 and tram 27 overlapping placements, and they just merge mutually like this.This process is to implement like this: in grid-shaped position 25, maintain passage 31, on this passage principle as common woven conveyer belt.Difference with the prior art is that organizine 26 and tram 27 are not as the mutual weave in of fabric, does not therefore form mesh, but the binding that produces thermoplastic filament by a heating process.
The thermoplastic filament partial schematic diagram that expression is amplified more in Fig. 4, this long filament are two composition long filaments.This long filament has a fusible top layer 30, and it surrounds one can not fusion or the sandwich layer 29 of higher melt arranged.When the grid-shaped position that makes according to Fig. 3 is top layer 30 fusions, and sandwich layer 29 guarantees conveyer belts 13 desired shape stabilities.
The local figure Fig. 5 that more amplifies than Fig. 1 has showed the position of the output jaw line 20 that grips roller 19 and conveyer belt 13 formation.Owing to the fiber strip 2 of the reason of describing with pending cohesion dispenses in Fig. 5.As seen from the figure, produce a kind of micro-textured between elasticity cladding thing that grips roller 19 and conveyer belt 13, this reticulate pattern particularly works when attaching troops to a unit on the side 32 of fiber strip 2 when tram 27 is arranged in very much.
From the Fig. 6 that represents aforesaid prior art, can know and see, if conveyer belt is a kind of woven fabric of producing with organizine 26 ' and tram 27 ' by common mode, the so-called micro-textured between the elasticity cladding thing that grips roller 19 and conveyer belt 13 ' just seldom plays effect.
