Description
Technical field
The present invention relates to a kind of saw tooth metal wire that is used to make the sawtooth all-steel card clothing that is used for processing textile fibres, especially for the sawtooth all-steel card clothing of making the carding machine doffer.This wire has a plurality of teeth that vertically are provided with continuously along wire, and each tooth has the increment face that extends from tooth root towards the crown direction, reaches the back of tooth that extends towards next tooth root direction from crown.
Background technology
Combing
Carding machine is provided with various cleanings and/or combing zone.Fiber feed is that the form with cotton-wool supplies to carding machine.Described cotton-wool is at first by licker-in (also claiming licker-in roller in the past) pre-cleaning.Described licker-in comprises one to three roller with coarse relatively card clothing, and this bodkin cloth is further opened cotton-wool, transfers them to cylinder then.Fiber with the form of nonwoven fabric material from cylinder doff and the outlet that is sent to carding machine to form ribbon.The operational mode of doffer is known for one of ordinary skill in the art, and for example summed up and explained: (author W. gram Lay mattress between blowing room and comb and parallel cotton fibers prior to spinning in the 2nd in textile machine handbook " short staple spinning factory ", publisher: weaving association), the 50th page.
Bondedfibre fabric doffs
In having the carding machine of relative traditional structure, be known that and produce some problems relevant with the card clothing of doffer.According to document EP-A-1136599, what shown is, can be by the fiber matting that doffer is taken away prematurely from the doffer shredding, and particularly under high product weight, this can have problems in the further processing of fibrous material.In order to eliminate these problems, the sawtooth that has proposed the sawtooth all-steel card clothing of doffer should be provided with horizontal roll groove structure.
Yet, detailed description according to EP-A-1136599, shown also that particularly in output be in 80kg or the above high yield carding machine, under the high peripheral speed of the doffer that therefore reaches, although the roll groove structure of the flank of tooth has improved confining force, fiber matting still can take place from the too early shredding of doffer.Therefore EP-A-1136599 has proposed another kind of solution at this problem, solves solution according to this, and the back of tooth has the cross section of special shaping, and the confining force that is produced by the card clothing on the bondedfibre fabric will be improved in this cross section.Yet this EP specification does not propose other change on the geometry of tooth.The improvement of the tooth of discussing among the EP-A-1136599 can be used in combination with the present invention, though these improve the following problem under various situations that do not solve.
In the high yield carding machine of latest generation, for example, the special C60 in lining, the working width of the cylinder present conventional value in the 1m scope are increased to 1.5m.In addition, the diameter of cylinder is reduced to about 0.814m from the 1.3m of present routine.Carding machine with the cylinder diameter that reduces is more suitable for moving under high relatively rotating speed, to obtain bigger centrifugal force.Because improved physical dimension and corresponding improved machined parameters, carding machine now can be with the output processing cotton-wool greater than 180kg/h.But, at least for some cotton mill, for example in the Asia, the carding machine of the type also can be produced thin relatively ribbon (for example the ribbon number is in 4 to 6,000 spies' (ktex) scope), this causes the high relatively velocity of discharge, also means to have brought the relative high rotating speed of all rollers in doff zone and discharging area thereupon.
These improved operative relations have direct influence to the lip-deep fibre density of doffer (doffer " occupying ").Bondedfibre fabric in the doffer card clothing relative thin (pine) that becomes.Therefore, the problem of the too early shredding of fiber matting takes place day by day, particularly at the downside of doffer.Under roller rotating speed that also will be higher at present under consideration for the carding machine of working width, because the low problem that causes of the bondedfibre fabric density on the doffer also can take place in these machines with about 1m.
Summary of the invention
In view of these problems of the prior art, the object of the present invention is to provide a kind of saw tooth metal wire, it can be used for making the sawtooth all-steel card clothing of the doffer of carding machine, and described sawtooth all-steel card clothing can be avoided the too early shredding of fiber matting reliably.
According to the present invention, this purpose is to finish by the technical characterictic of independent claims.
The saw tooth metal wire that is used for textile fabric processing can be made like this, forms the wire with laminar cross section, punching press sawtooth on this laminar cross section then by the processing original material.

The specific embodiment
Fig. 1 is the schematic diagram that shows the revolving flats carding machine, for example in special C60 carding machine, it has the working width greater than 1.3m, particularly 1.5m.Principle of the present invention can be applied to the working width until 2m, and also can be used for having the carding machine of the conventional operation width of about 1m.The working width of carding machine is determined effectively by the axial length on the card clothing surface on the cylinder 1.
Be in operation, fibre bundle is carried through different opening picking process segment (not shown) by Pneumatic conveying pipeline, forms cotton-wool then in the feed chute 16 of carding machine.Skewed slot 16 among Fig. 1 is designed to so-called " cleaner skewed slot ", and it has the cleaning module 15 between skewed slot top and skewed slot bottom.Yet this is unessential for the present invention, also can be provided with conventional feed chute and replace the cleaner skewed slot.This skewed slot is transported to carding machine with fiber with the form of cotton-wool then, particularly is transported to known feed arrangement (not illustrating especially), and this feed arrangement is pulled into cotton-wool in the carding machine at a predetermined velocity.
Feed arrangement is fed into licker-in module 3 with fiber.Licker-in module 3 among Fig. 1 comprises a plurality of licker-in rollers, but also can only be provided with a licker-in.Fibre bundle is by further shredding in licker-in module 3, and some dirt particles are removed.Should (last) licker-in roller transmitting fiber tow be passed to combing cylinder 1.Combing cylinder (angular range ∑) in so-called main combing scope 8 is cooperated with cover plate 7, whereby with fiber opener and further cleaning.Cover plate 7 drives by driving belt, and this driving belt is by the guiding roller or drive roller 6 guiding.Cover plate 7 tegmentum board cleaning devices 14 cleanings, and finally polished again by sanding apparatus.
The pre-comb zone is between licker-in and main combing zone, and back combing zone is located between main combing zone and the doffer.Fixing cleaning element arranges for example have the securing cover plate of card clothing, cutter and aspirator, is arranged on usually in pre-comb district and the combing district, back.
Inferior combing district is positioned between doffer 4 and the licker-in, and it is differently constructed according to manufactured goods.
Fiber the part after repeatedly rotating on the combing cylinder 1, fiber is removed from combing cylinder 1 by doffer 4 with the form of soft bondedfibre fabric, and be sent to discharging area 5, leave in the bar tube (not shown) as ribbon by means of can coiler at last.As restraining the Lay mattress described in the aforementioned handbook, doffer 4 must be provided with special Card Clothing finishing the work.The standard design of this card clothing uses at present anterior angle α in 20 ° to 30 ° scopes (to consult gram Lay mattress, the card clothing form of the 54th page in above-mentioned handbook and the 55th page; Also can be referring to EP-A-1136599, the 5th hurdle, the 1st to 3 row).The gyratory directions of doffer 4 represents with arrow A that in Fig. 1 Reference numeral Z represents one " card clothing tooth ", and this card clothing tooth is exaggerated in this figure and illustrates, so that the layout of the circumferential surface of the relative roller 4 of the schematically illustrated flank of tooth.
As described in the preamble, the doffer card clothing may apply too low holding power to the fiber matting that almost can not bond mutually.As among Fig. 1 by arrow P schematically illustrated, at the downside of doffer 4, so bondedfibre fabric is easy to unclamp and fall or take off from card clothing.This may be in operation and cause sizable interference.A kind of part solution is to install the downside of a coaming plate to doffer.But this can not eliminate the cause of problem.
Therefore, the present invention seeks a kind of remedying in the new improvement of doffer card clothing or saw tooth metal wire for this reason, as hereinafter described with reference to Fig. 3 and Fig. 4.With reference to Fig. 2, at first describe prior art in detail.
