Abstract
The invention relates to a rifle-shaped felting needle. The felting needle consists of a needle rod, a middle section and a working section which are integrated; the ridge of the working section is rifle-shaped; and fiber storage grooves are formed between the adjacent ridges. The designed needle form is particularly suitable for weaving of thick and compact fibers, and weaving of nonwoven fabric which has high fragility (such as ceramic fiber, glass fiber and the like) or nonwoven fabric which has high friction force (such as carbon fiber, stainless steel fiber, aramid fiber, high-strength polyethylene fiber and the like). The felting needle can be used for weaving carbon fiber members used for aerospace.
Description
Technical field
The present invention relates to a kind of equipment of producing non-weaving cloth, particularly a kind of needing machine parts.
Background technology
Pricker is the important devices of producing nonwoven fabric, and it is puncture up and down at a high speed on fiber web layer, makes fiber and fiber entangled to each other, forms various non-weaving cloths.Traditional nonwoven pricking pin is made up of the shank that is made into integration, middle shank and coupler body, and the crochet hook body is triangular prism, and each rib is the peak shape, all is arranged in order a plurality of briar tooths on it.Because a plurality of briar tooths are arranged in a straight line, in piercing process, after first briar tooth colluded fiber at random, the probability that briar tooth thereafter colludes fiber will obviously reduce, and operating efficiency is low.
The patent No. is: 200620101167.8; Patent name is the triangular spiral pricker that head it off discloses a kind of crochet hook body for the utility model patent of " spirality nonwoven pricking pin "; The triangular briar tooth that is provided with; Like this; See with respect to knitting laminar surface; Each briar tooth on each rib all has the effect of first tooth; Therefore; In piercing process, the probability that colludes fiber at random significantly improves, and obviously enhances productivity; Solved the loose of no latitude thin non-woven fabric; Shortcomings such as tensile strength difference; Though this pin type has improved production efficiency, because it is specially adapted to low grammes per square metre; The production of the thin non-woven fabric of no graticule, thereby range of application is narrow.
But along with development of science and technology, the Application Areas of non-weaving cloth is more and more wider, and the specialty fibers member that some special dimensions use is higher to the performance requirement of non-weaving cloth, belongs to the specialty fibers of thick and heavy type tight type.As: ceramic fibre; Unlubricated formulation fibers such as carbon fiber, glass fibre, stainless steel fibre, aramid fiber; Because fiber itself fragility is bigger; Frictional force between fiber and the fiber is bigger, and coefficient of friction is big, thereby; Existing pin type is heavier to pulling of fiber itself; Fiber itself is destroyed, and causes fiber web layer to form defectives such as layering, has directly destroyed the performance of nonwoven.
Each item performance indications of the carbon fiber construction that Aero-Space are used require very strict, have higher entanglement power and cohesive force between special demands fiber and the fiber, yet, use the existing woven non-weaving cloth of pin type can not satisfy related request.
Summary of the invention
The object of the invention is primarily aimed at the shortcoming of prior art, provide a kind of reduce the frictional force between fiber and the fiber and guarantee that top fiber is smooth and easy penetrate the rifle shape pricker that fibre web and lower floor's fiber fully tangle.
Technical scheme of the present invention is: a kind of rifle shape pricker, to form by the shank that is made into integration, interlude and active section, and the rib crestal line of described active section is the rifle shape, is provided with fibre storing groove between adjacent two rib crestal lines.
Preferably: described fibre storing groove is set to groove, and is provided with a fibre storing groove at least between adjacent two rib crestal lines.
Preferably: the active section of described pricker is set to the triangle cylindricality, and the rib crestal line of active section is the rifle shape, and the both sides of rib crestal line are provided with fibre storing groove.
Preferably: the active section of described pricker is set to triangular pyramid shape, and the rib crestal line of active section is the rifle shape, and the both sides of rib crestal line are provided with fibre storing groove.
Preferably: the active section of described pricker is set to the star cylindricality, and the rib crestal line of active section is the rifle shape, and the both sides of two rib crestal lines are provided with fibre storing groove.
Preferably: the active section of described pricker is set to star awl cylindricality, and the rib crestal line of active section is the rifle shape, and the both sides of two rib crestal lines are provided with fibre storing groove.
Preferably: the active section of described pricker is set to quadrangular prism shape, and the rib crestal line of active section is the rifle shape, and the both sides of rib crestal line are provided with fibre storing groove.
Preferably: the active section of described pricker is set to the quadrangular pyramid cylindricality, and the rib crestal line of active section is the rifle shape, and the both sides of rib crestal line are provided with fibre storing groove.
Preferably: the cross sectional shape of described groove is circular arc, trapezoidal, rectangle, triangle, involute shape, parabola shaped or corrugated.
Preferably: described rib crestal line is provided with the thorn hook, and the quantity of thorn hook is set to 1-32.
Beneficial effect of the present invention is: the pin type of the present invention's design is specially adapted to weaving of thick and heavy type tight type fiber; Be specially adapted to fragility big (as: ceramic fibre, glass fibre etc.), frictional force is the weaving of nonwoven of the fiber of big (as: carbon fiber, stainless steel fibre, aramid fiber, high-tenacity polyethylene fibre etc.).Can be used for weaving the Aero-Space carbon fiber construction.
The present invention derives from rifling in the rifle chamber; The principle of rotation after allowing bullet fly out; In pricker puncture fiber web process; The fiber that is squeezed is hidden in the fibre storing groove of good fortune wire; With thorn needle penetration fiber web,, help combining between fiber and the fiber more to reach protection fiber and the effect of the fiber that institute is colluded hold along rifle formation helical fiber post; Make that the cohesive force of product is stronger, defectives such as nonwoven layering can not occur.Owing to be provided with fibre storing groove; During entanglement, reduced the direct friction between fiber and the fiber, avoided pulling and fibrous fracture that frictional resistance causes greatly fiber itself; Improved the delamination power of fabric greatly and, promoted the performance of fabric on the whole in length and breadth to pulling force.Simultaneously, structural design of the present invention has strengthened the bending resistance of needle body, the anti-performance that fractures greatly.
The present invention form perpendicular to the infiltration more easily when impregnate with bitumen filler or epoxy resin filler when the fibrous structures deep processing of the helical fiber post of fiber web layer.
