Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of pricker, the anti-disconnected nonwoven pricking pin of particularly a kind of star.
Background technology
In making needle punched non-woven fabrics, the triangle pricker be main also be the most general pricker, it is applied to the manufacturing of all kinds of nonwoven fabric in a large number.In general acupuncture nonwoven production process, no matter rationally the selecting for use of common triangle pricker is in pre-thorn, main thorn or have a shave aspect pin, can satisfy production requirement basically.
But along with the improvement of technology and the raising of nonwoven production requirement, this type of triangle pricker can not be satisfied with new production requirement far away, the limitation that common triangle working face exists, make it seem beyond one's ability, can't satisfy the bondedfibre fabric production requirement of some high density, high strength acupuncture effect in application facet such as high strength, crude fibres.Common cutting needle seems on the industrial blanket of producing such as the high grammes per square metre of high thickness and greatly reduces service life by easy to wear, easy broken needle.In addition, this type of triangle pricker also can't satisfy the requirement on the fibre matting rate.
Find no this by retrieval and be specifically designed to the anti-disconnected type pricker that improves fabric property; therefore; therefore; just need invention to be used for the pricker of high-density high-strength fabric; on the basis of common pricker, improve and promote the anti-disconnected property of pricker; reach desirable efficiently acupuncture effect, when improving the quality of products, farthest protect fiber again.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, provide a kind of simple in structure, hardness is higher, tension and breaking strength preferably, service life is long, and can significantly improve the anti-disconnected nonwoven pricking pin of star of fibre matting rate.
The purpose of this utility model can realize by following technical proposal: the anti-disconnected nonwoven pricking pin of a kind of star, comprise shank and the operate portions of being located at shank end, described operate portions has needle point foremost, described operate portions is prism-shaped, it is characterized in that, the cross section of described operate portions is star, is provided with several briar tooths on the operate portions seamed edge.
The anti-disconnected nonwoven pricking pin of this star is specifically designed to produces high-density high-strength, high grammes per square metre high-performance bondedfibre fabric.Shank is used for linking with machine, operate portions is used for the fiber that punctures, the star design in the cross section of operate portions, compare with traditional standard operation portion, the advantage of this pricker uniqueness has been given in the cross section of star, anti-disconnected wear-resisting, has higher service life, combine powerful working position and star cross section, improved acupuncture efficient greatly, especially be used in and make high grammes per square metre geotextiles of high density and the industrial blanket of various science and technology, the anti-disconnected nonwoven pricking pin of this star does not damage under the prerequisite of fiber having guaranteed, largely improve the entanglement rate of fiber, improved the fabric flow velocity, thereby reached better economic benefit.
In the anti-disconnected nonwoven pricking pin of above-mentioned star, described operate portions is the quadrangular shape, and is concave arc shape between the two adjacent seamed edges, and the cross section of described operate portions is four jiaos of starriness.Several briar tooths of offering on operate portions and adjacent two seamed edges are designed to be concave arc shape make this pricker in the processing and manufacturing process of nonwoven fabric, can more effectively bring the fiber of q.s into.The Cross section Design of operate portions is become four jiaos of starriness, compare, four briar tooths are arranged on the equal depth of needling with traditional triangle pricker, more multi-fibre enables to tangle, increase the elasticity of fabric, reached more intensive acupuncture effect, thereby promoted the density and the intensity of fabric.When the assurance quality of production is reliable and stable, improved the economic benefit of acupuncture greatly.
In the anti-disconnected nonwoven pricking pin of above-mentioned star, described shank is made up of shank one and shank two, and shank one, shank two and above-mentioned operate portions are integral structure.The three is designed to integral structure, makes the firm performance of this pricker better, also reduced the processing technology of making this pricker.
In the anti-disconnected nonwoven pricking pin of above-mentioned star, described shank and operate portions all adopt ZH041 eedle proprietary material to make.The shank and the operate portions that adopt ZH041 eedle proprietary material to make have very high rigidity intensity and hardness, make this pricker have higher anti-disconnected performance and more superior stability like this, have also prolonged the service life of this pricker certainly.
In the anti-disconnected nonwoven pricking pin of above-mentioned star, the external diameter of described shank one is greater than the external diameter of shank two.With the external diameter of shank one external diameter, make this pricker be convenient to puncture greater than shank two.
In the anti-disconnected nonwoven pricking pin of above-mentioned star, described shank one end also has with shank 11 decides the connecting portion of angle.Make things convenient for pricker to be connected by this connecting portion with machine.
Compared with prior art, the anti-disconnected nonwoven pricking pin of this star has the following advantages:
1, the cross section of the operate portions of the anti-disconnected nonwoven pricking pin of this star is four jiaos of starriness, makes operate portions all have briar tooth at the four direction of solid, makes briar tooth bring more fiber into, and stressed evenly it is also more even to distribute, and guarantees the neat and consistent of fabric.
2, make it to puncture more multi-fibre and keeping consistency of the anti-disconnected designed angle of the every seamed edge of nonwoven pricking pin operate portions of this star, do not damage fiber when guaranteeing the high entanglement rate of fiber, increased the elasticity and the surface smoothness of fabric with the briar tooth that designs on the seamed edge of certain fillet and the rib.
3, the shank of the anti-disconnected nonwoven pricking pin of this star and operate portions adopt ZH041 eedle proprietary material to make, and make this pricker have higher rigidity intensity, hardness and anti-disconnected property.
4, the anti-disconnected nonwoven pricking pin applied range of this star, useful fiber thickness scope is big, and some specialty fibers such as various artificial fibres, PP, PET and blended fiber all can be used.Particularly be applied in and make in high thickness, the industrial blanket of high grammes per square metre, as antifouling blowdown apparatus, waterproof bed course etc., the anti-disconnected nonwoven pricking pin of this star more can manifest its superiority.
5, the operate portions of the anti-disconnected nonwoven pricking pin uniqueness of this star and briar tooth design have promoted the anti-disconnected performance of pricker greatly, have improved service life, reduce adjusting machine time and shutdown loss, have reached the acupuncture effect of efficient unanimity.
