Description

Combing element

Technical field

The present invention relates to a kind of combing element that is used for the cylinder needle plate seat board of cylinder roller, it can rotate around rotation in weaving loom of combing cotton fiber being used for.

Background technology

Be used in the combing machine comb since disclosed previous application be well-known, wherein on a matrix, at least one combing element is set, it with treat that the cotton fiber of combing is chimeric.Effective combing district of one of them circle comb for example can be 78 °, 90 °, 111 °, 180 ° or whole circumference of circle comb outer body line circumference.One has along the circle comb in effective combing district of whole circumference and is called 360 ° of circle combs.Color pin, pin bar, serrated teeth steel wire section, broach or the punching press of zigzag part are as combing element, and wherein the combing element of prepackage is called tie-rod or cylinder pin holder.

The cylinder pin holder has for example many toothed combing elements that are arranged side by side along cylinder rotation axis of roller direction, the for example tooth of zigzag stamping parts or fluted disc form.Tooth and it influence the carding effect of cylinder pin holder around the layout of the direction of rotation of rotation on cylinder pin holder upper edge rotation direction and edge.In addition, the fiber that cleaning is combed out from the fluted disc of cylinder pin holder also depends on the moulding and the layout on the cylinder pin holder thereof of tooth.

DE3904178A1 illustrate one have many combing elements the cylinder pin holder, combing element has a large amount of different teeth respectively.By the known tooth of DE19956911A1 with non-rectangle cross-sectional geometry, the non-rectangle zone line between the tooth of the adjacent combing element of formation cylinder pin holder.

Combing effect to fiber embeds the fiber assurance of treating combing through tooth, and wherein institute's carded fiber is through the middle cavity between two adjacent teeth of cylinder pin holder.Combing effect strengthens when the size of middle cavity reduces in principle, but has reduced the accessibility of tooth middle cavity thus, and particle and/or fibre composition that its cleaning, particularly removal are combed out are difficult more.Therefore demonstrate for tie-rod and hope high carding effect and the conflicting structural requirement of accessibility that the between cog cavity is good on the other hand on the one hand.

Summary of the invention

The objective of the invention is, improve the combing element of the cylinder pin holder that is used for the combing cotton like this, make and in addition can clear up the between cog cavity without a doubt with high carding effect.

According to the present invention, achieve this end through combing element with the characteristic that in claim 1, provides.

Be used for and can comprise around the combing element of this invention of the cylinder pin holder of the cylinder roller of rotation rotation: root, this root have one along the crooked shell surface of surface line; The a plurality of teeth that extend radially outward with respect to rotation and be provided with along the surface line order from shell surface; And a plurality ofly being separately positioned on two between cog cavitys between the adjacent tooth, said between cog cavity makes the fiber of institute's combing under the situation of certain radially insert depth, can pass through along the fiber direction of passage respectively.Wherein each tooth has four tip surface limits; Wherein in a between cog cavity, one limit the between cog cavity first tooth confirm an imaginary along the surface line front with along between the tip surface limit of fiber direction of passage back, and the combing angle α of at least 15 ° of surface line and connecting clamp along second tooth surface line back and limit the between cog cavity along the tip surface limit and of fiber direction of passage front.Through the present invention the regulation of meshingangle is realized that best comb is clean owing to treat the high carding effect of combing cotton fiber, and guarantee the operation that each root fiber is soft on the other hand, make and have only the small amount of fibers fracture and shorten thus.Combing element of the present invention also can be used for such cylinder pin holder, its be installed on the cylinder roller and greater than 450 combing circulation/minute and greater than 500 combing circulation/minute situation under move.There is such danger in high like this combing rotating speed, i.e. the fiber of institute's combing confirms promptly that almost in the outer end of tooth the so-called combing radius of an envelope cylinder is flown over, because fiber does not fully embed the between cog cavity.Make fiber be convenient to get into the between cog cavity through combing element, thereby even when described high combing rotating speed, also avoid fiber to fly over from the side by structure of the present invention.The combing angle is radially strengthened at least piecemeal, and the difference according to the fiber type of institute's combing has improved the requirement of carding effect with the cleaning possibility thus.

In combing element structure, individually require carding effect and cleaning possibility to be complementary according to the fiber type of treating combing by

claim

2 or 3.

Making by the combing element of claim 4 can be good especially, stable and have the carding process of high carding effect continuously; Because tooth remains in the between cog cavity the active force of the fiber fiber with institute's combing, and prevent thus for example to make fiber all of a sudden leave the between cog cavity owing to move up.

Structure by means of by the combing element of claim 5 to 7 can obtain along the favourable influence of the combing angle α of combing element surface line.Can change carding effect thus and in a combing element cleaning possibility of between cog cavity so that for example improving carding effect in the situation lower edge surface line that insert depth remains unchanged.For this reason, strengthen combing angle α or increasing step by step along surface line.Cycle through along surface line combing angle α is strengthened the carding effect that the cycle that reaches changes.It is characterized in that, on the one hand through adopting the tangible pulling force of circle comb of the present invention different sizes of effect on the fiber of institute's combing.Produce different strong and weak power through the friction of fiber on the tip surface limit for this reason, thereby strengthened the cleaning of fiber thus and improved carding effect generally.In single fiber, cause different tension force on the other hand, therefore in general reduce fibre matting.

The combing element with combing angle α by claim 8 is particularly suitable for the long fiber cotton that noil length surpasses 33mm; It needs at least 18 ° meshingangle; And be suitable for processing the mixture of cotton and synthetic fiber, the combing element that this is had at least 20 ° of combing angles is favourable.

Improved by the combing element of claim 9 and to have confirmed aspect the α of combing angle and particularly to change along the various shapes property of the combing angle α of combing element surface line.

It is good especially being proved to be reaching aspect the carding effect by the combing element structure of claim 10 to 12.The fiber of combing in the between cog cavity is when the contrary radial direction in combing angle reduces because at the bottom of the reaction force on tip surface limit drawn in tooth by contrary radial direction in maximum combing angular region.Therefore stable especially with the carding process of the combing element of this moulding.Especially high greater than 450 combing circulation/minute and greater than 500 combing circulation/minute the combing rotating speed time, avoid fiber to fly over through such method, thereby cause the improvement of carding effect at the outer most advanced and sophisticated place of tooth.

Combing element moulding by claim 13 makes tooth can mildly embed the fiber of institute's combing.By the tip surface limit of tooth rounding, the stress of the fiber of institute's combing through the between cog cavity time reduces, thereby reduces the danger of fibrous fracture.Correspondingly, confirm combing angle α through the contact point of fiber on the tip surface limit of rounding.
