Abstract
The invention belongs to the technical field of machinery, relates to a non-woven felting needle, and particularly relates to a felting needle special for nonwoven fabric surface raising. The felting needle comprises a needle handle and a joint pin arranged at end part of the needle handle, wherein a needle tip is arranged at the most front end of the joint pin; and a hooked thorn is arranged between the needle tip and the joint pin. The felting needle is characterized in that the section of the hooked thorn is triangular, each corner of the triangle is provided with a hooked thorn, the distance between hooked thorns of every two corners is only 0.1 millimeter, so that the fact that fibres can be simultaneously caught in a raising process is guaranteed. The needle handle, the joint pin and the hooked thorn and the needle tip are designed into an integrated structure which is characterized in that the hooked thorn is in a coronary shape and the diameter of the needle handle is larger than that of the joint pin, so that the tensile and breaking strength of the felting needle is improved, the technical problem that the requirements on fibre transfer efficiency are met is solved, and in the process of finally processing an automobile lining or a carpet, a layer of tight and high quality plush surface can be formed at the surface of the automobile lining or the carpet, and needle marks do not exist.
Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of nonwoven pricking pin, particularly a kind of nonwoven surface napping Special felting needle.
Background technology
In making nonwoven fabric pricker process, common pricker is the pricker of commonly using, he is widely used in weaving of all kinds of nonwoven fabric, but along with the improvement of technique and the raising of nonwoven production requirement, add the specific demand of relevant napping operation, above-mentioned pricker can not meet relevant needs far away, original pricker does not work in the surface nappy operation of inner lining of automobile or carpet, be badly in need of that design is a kind of can, at the Special felting needle of the surface nappy of inner lining of automobile or carpet, meet above-mentioned need of production.
Find no special pricker as inner lining of automobile or carpet surface napping operation through retrieval, just be badly in need of the nonwoven surface napping Special felting needle of this special use of invention, make it to reach efficient desirable napping effect, be both and protect to greatest extent fiber.
Summary of the invention
The objective of the invention is to improve for existing above-mentioned technical problem, design a kind of simple in structure, hardness is higher, tension and breaking strength Special felting needle preferably, and service life is longer, reaches and significantly improves the napping effect.
the present invention can realize by following scheme: a kind of nonwoven surface napping Special felting needle, comprise needle handle and the joint pin of being located at the needle handle end, described joint pin has needle point foremost, be provided with between needle point and joint pin and hook thorn, it is characterized in that, the cross section of described hook thorn is triangular in shape, each corner of triangle is provided with one and hooks thorn, the H value of the A angular distance needle point in triangle is 3.2 millimeters, the H value of B angular distance needle point is 3.3 millimeters, the H value of C angular distance needle point is 3.4 millimeters, making each angle hook the thorn distance is only 0.1 millimeter, can guarantee can catch simultaneously fiber in the napping process, and with the form of the looped pile that is shaped uniformly, pass fabric.
This nonwoven surface napping Special felting needle is to be used for specially Special felting needle at the surface nappy of inner lining of automobile or carpet, therefore needle handle, joint pin, hook thorn, needle point are designed to as the integral type structure, it is characterized in that hooking thorn and be " crown " shape, the diameter of needle handle is greater than the diameter of joint pin, can improve its tension and breaking strength, meet the technical problems such as requirement on the fiber efficiency of transmission, finally add man-hour at inner lining of automobile or carpet, can produce on its surface one deck high-quality lint surface closely, and not produce pin trace phenomenon.

Fig. 2 is that K of the present invention is to (needle point direction of observation) zoomed-in view
Fig. 3 is that the present invention hooks thorn and tip portion partial enlarged view
Description of drawings
a kind of nonwoven surface napping Special felting needle, comprise needle handle 1 and the joint pin 2 of being located at the needle handle end, described joint pin 2 has needle point 4 foremost, be provided with between needle point 4 and joint pin 2 and hook thorn 3, it is characterized in that, the cross section of described hook thorn 3 is triangular in shape, each corner of triangle is provided with one and hooks thorn 3, the H value of the A angular distance needle point 4 in triangle is 3.2 millimeters, the H value of B angular distance needle point 4 is 3.3 millimeters, the H value of C angular distance needle point 4 is 3.4 millimeters, making each angle hook thorn 3 distances is only 0.1 millimeter, can guarantee can catch simultaneously fiber in the napping process, and with the form of the looped pile that is shaped uniformly, pass fabric.
This nonwoven surface napping Special felting needle is to be used for specially Special felting needle at the surface nappy of inner lining of automobile or carpet, therefore needle handle 1, joint pin 2, hook thorn 3, needle point 4 are designed to as the integral type structure, it is characterized in that hooking thorn 3 and be " crown " shape, the diameter of needle handle 1 is greater than the diameter of joint pin 2, can improve its tension and breaking strength, meet the technical problems such as requirement on the fiber efficiency of transmission, finally add man-hour at inner lining of automobile or carpet, can produce on its surface one deck high-quality lint surface closely, and not produce pin trace phenomenon.
