Description

Prewoven machine, particularly combing machine, the assembling of carding machine etc.

This invention is about prewoven machine, combing machine especially, carding machine and similarly have the assembling of the machine of or several zigzag card wires, the tooth that its card wire base portion is used for fixing on lonely shape card wire plate and has several to tilt to stretch out along the combing direction.Crown has a predetermined distance with respect to base portion, is called tooth depth.

The assembling of the profile of tooth card wire of the above-mentioned type, according to various purposes, its structure has various ways.For example, the ring like steel wire card clothing of a stretching is as the assembling form of a profile of tooth card wire, or each profile of tooth card wire only has a tooth, with a few row's card wire base portion welding, the assembling form that is fixed together.

But what particularly point out is to having the assembling of multiple tooth profile of tooth card wire, in a row settles successively as six teeth, and the tooth that several rows are such is installed on doffer's the curved comb needle plate with the method for joggle.

Investigation shows that in order to reach the carding effect of expection, except that some other parameter, crown is high to have played important function with the crown spacing of facing the profile of tooth card wire mutually that is parallel to each other.

The spacing of facing the dentation card wire mutually plays a decisive role to the free path of fiber.If spacing is little, under very big pressure, can not make the mutual alignment of each single fiber, thereby may reduce carding effect, on the other hand, spacing is too small to be that corresponding free path is too small, may make fiber can not obtain enough stretchings and combing.Be pulled through on the needle point and only float over, and combing sometimes less than.

For above-mentioned reasons, this invention is logical and flow and a kind of assembling form of considering to propose for the comb that improves fiber.

The present invention can realize this purpose.When seeing perpendicular to the combing direction, the dentation card wire has two kinds of different height (with regard to the doffer, be parallel to this doffer's rotor shaft direction and promptly think perpendicular to the combing direction) at least.By this structure in this invention, the kinematics of fiber carding process influences carding effect effectively.Because the effect of short tooth.Fiber is held and brings into the concentrated combing district that tooth root forms.In this zone, short tooth also produces certain pressure to fiber, has played the effect that removal of impurities and comb are led.Therefore, according to this invention,, can avoid the floating of fiber to move because drawing zone produces relatively large free path.On the other hand, because enough concentrated combings have been guaranteed in the effect of short tooth.Particularly when length tooth tooth depth difference greater than long tooth 1/5 the time effect better.

According to the method for optimizing of embodiment, the profile of tooth card wire of different tooth depths is provided, the tooth depth of single card wire self is identical, and the card wire of different tooth depths is installed along replacing in a row perpendicular to the combing direction.

Owing between the profile of tooth card wire of big tooth depth, formed the path that is parallel to profile of tooth card wire face, denticulate profile of tooth card wire be installed in the bottom of this path.In order to improve carding effect, the plane that can make the profile of tooth card wire acutangulates (this mode will have narration later) with doffer's frontal plane perpendicular to rotating shaft.

Under any circumstance, fiber is drawn in above-mentioned path reliably by long tooth, and all by the combing once more of short tooth.The spacing size that vertically goes up between the crown along the curved comb crown is to determine according to the raw material of being processed is different.This layout can make each profile of tooth card wire root abut against together, and makes crown obtain certain clearance by the abrasive point tooth, and the pad identical with the base portion height or pad and base portion are made one become shoulder (will there be narration this kind mode back) of also can packing into.

According to the present invention, the method for another kind of embodiment is along the pin tooth of alternately arranging and having different tooth depths on the combing direction with each profile of tooth card wire.The advantage of this structure is only to use the profile of tooth card wire work of same structure, and in fact, this also is the special benefits of annular card wire assembly structure.

This structure makes the little tooth of each platoon leader's between cog form path on a direction.Along the arranging successively of vertical face, the direction of this path forms an angle with doffer's frontal plane perpendicular to rotating shaft according to selected dentation card wire.The working method of this structure is identical with principle mentioned above.

In the method for these two kinds of embodiment, more preferably the profile of tooth card wire is along in a row settling perpendicular to the combing aspect, the crown of arranging the profile of tooth card wire of putting one by one is interlaced, its spacing is half of two adjacent card wire tooth pitches, this effect can have the locating slot of different rigging positions by the base portion at the dentation card wire, can obtain staggered assembling naturally.By this staggered assembling, can make the distribution of crown on fitting surface even as far as possible.

Mentioned two types profile of tooth card wire to this, every kind of card wire has different tooth depths.The tooth depth of short tooth be preferably long tooth crown high 1/20 to 2/3.When specifically being used for comb and parallel cotton fibers prior to spinning, tooth depth is preferably 8: 20, and when being used for carding, the tooth depth ratio is 8: 25.

The regularly arranged effect of crown is better, if but in fact the dentation card wire of little tooth depth has only close external diameter, on principle, also can obtain the effect that this invention will reach.Each tooth is all arranged regularly, and for each tooth, also unnecessary with a position of fixing is arranged between its tooth mutually.

From following elite embodiment, can further see feature, advantage and the characteristic of this invention.

Fig. 9 is corresponding to Fig. 8, is used for the side view of the embodiment of carding.

In Fig. 1, represent the profile of tooth card wire 1 of design with a so-called ring-type card wire according to the present invention.In the preparation of strip card wire,

tooth

5,6 is positioned at and shoulder pad platform 3, and top seamed edge 4 is on the base portion 2 of one.Tooth depth H is defined as the distance from the top seamed edge 4 on the division base portion to tooth 5 tops.Tooth 6 is risen than tooth 5 and is risen the little X of H.

Figure 2 shows that corresponding card wire, this figure is a sectional view, and two row's pin teeth replace overlapping and separated by pad 7.In above-mentioned arrangement, part 8,9 is interlaced, and its little tooth 6 just is positioned at after the canine tooth that tooth depth is H.

Figure 3 shows that 10, the 11 overlapped configurations of two kinds of profile of tooth card wires.This moment, front-seat dentation card wire 10 was little tooth entirely, and the more front-seat high X of tooth depth of the tooth 5 of row's dentation card wire 11 after placing.Profile of

tooth card wire

10 and 11 so mutual alternate configurations form the crowns, and the crown passes slotted eye 12 on

card wire

10,11 base portions 13 and fixing (not shown) by the connecting rod that longitudinally stretches out.

The

crown

14,15 of profile of

tooth card wire

10,11 is interlaced.Staggered half of two adjacent teeth point 14 spacing A of being approximately apart from V.

Profile of

tooth card wire

10,11 closely row is put, and crown is subjected to the influence of the grinding situation of

tooth

5 or 6 apart from S.

As shown in Figure 7, the crown of profile of

tooth card wire

10,11 in a row can be fixed on the curved comb crown 17 by dovetail groove 16.

This mounting means make the crown 15 of the crown 14 of canine tooth 5 and little tooth 6 lay respectively at run-on point M be the center circular arc 18 and 18 ' on.The radius R of outer arc 18 can be used to represent the tolerance of corresponding tooth depth H.

Structure shown in Figure 4 is equivalent to Fig. 3 structure on principle.But in the structure of this tooth, right rather than represent different profile of

tooth card wires

10,11 with the difference of tooth depth although the per tooth height is identical, but shown in profile of tooth card wire 19, when when direction of rotation D observes, canine tooth 5 and little tooth 6 replace mutually.In this instantiation, its base portion 20 have one with the corresponding shoulder pad platform 21 of Fig. 1 embodiment.

Among the embodiment shown in Figure 5, profile of tooth card wire 22,23 has only a kind of

tooth

5 or 6 respectively.Profile of tooth card wire 22 has long tooth 5, and card wire 23 has short tooth 6.Profile of tooth card wire 22 and 23 is alternately settled mutually, and its base portion is linked together with soldering.

Fig. 6 is a kind of change according to the embodiment of Fig. 5, accompanies pad 25 between profile of tooth card wire 22 and 23.

The layout of the profile of

tooth card wire

10,11 of Fig. 7 presentation graphs 3 shown types and be fixed on only reduced representation among the doffer 26(figure) on the connection of arc needle plate 17.Profile of

tooth card wire

Be also pointed out that the profile of tooth card wire might not be assemblied on the supporting mass by a fixed head such as curved comb needle plate in the present invention.The profile of tooth card wire also can directly be fixed on supporting mass and promptly be fixed on the doffer.

Fig. 8,9 corresponds essentially to concrete mechanism shown in Figure 3 from describing in detail perpendicular to the combing direction or perpendicular to direction of rotation D and the direction that is parallel to doffer 26 center longitudinal axis.Having short tooth 6(tooth depth is H-X) profile of tooth card wire 10 with to have long tooth 5(tooth depth be H) 11 one-tenth rows of mutually staggered of profile of tooth card wire settle.Concrete mechanism shown in Figure 8 is particularly suitable for comb and parallel cotton fibers prior to spinning, and the concrete mechanism of Fig. 9 can obtain good especially effect when carding.

In the embodiment shown in fig. 8, auxiliary limit before and after canine tooth has, when direction of rotation is seen, its gradient difference.The inclination angle on top 31 is bigger, and 32 inclination angles, bottom are less.Short tooth 6 is also similar substantially, and is just slicker and more sly.The tooth depth H-X of tooth 6 is roughly 8: 25 with respect to the ratio of the tooth depth H of canine tooth 5.

In the embodiment shown in fig. 9,

zone

31 and 32 is distinguished more mutually by break 33, and the tooth front side also is like this in principle.

High-quality assemble mechanism with assemble mechanism shown in Figure 8 and canonical form was made contrast test.What use in the test is cheap second-rate the Sudan cotton, and the specific question that this grows cotton for combing is that it contains sticky contaminant.The per 1000 meters long thick cotton hop count of result of the test reduces to 154 from 211, and per 1000 meters cotton junction number is kept to 128 by 211.

According to assemble mechanism shown in Figure 9, make in the contrast test of wool, the mean fracture load of wool by 2 grams rise to 294.6 grams, per 1000 meters thick cotton hop count reduces to 12 by 37, per 1000 meters cotton junction number reduces to 46 by 94.

The above results shows that even compare with the high-quality crown assembling of standard design form, this invention still obtains significant effect.
