Description
Technical field
The present invention relates to a kind of device for textile industry, is a kind of pricker producing non-weaving cloth, particularly relates to a kind of random point position pricker, and this pricker the mode of array can form bed use, in strengthening non-weaving cloth.
Background technology
Non-weaving cloth (non-wovenfabric, non-wovencloth) nonwoven fabric, Nonwovens is had another name called, textile staple or long filament are carried out orientation or supports row at random, form fibre net structure, then tailor's cushion machinery or the various fibrous raw material of carding machine process is adopted, with a kind of cloth-like thing that high pressure is formed or bonding is produced.Fiber can be the broken or artificial fibre synthetic fiber (glue, resin etc.) of cloth.
Non-weaving cloth to form by through knitting device unlike weaving cotton cloth, making of non-weaving cloth changes to some extent along with the difference of technique, as tailor's cushion method is through thousands of acupunctures constantly upper and lower acicular hook fiber, fiber is allowed to be entangled with each other, being entangled with each time can allow fiber more and more sturdy, thus forms the entirety of an agllutination reality.
Experiment shows, intensity and the puncture technique of non-weaving cloth have close relationship, especially more obvious in isotropic non-weaving cloth.Puncture number of times is more, more intensive, is just entangled with tightr between fiber, and the intensity of obtained non-weaving cloth is also higher; Otherwise, its intensity step-down can be caused.
In prior art, in order to obtain the non-weaving cloth of high strength, must repeated multiple times ground puncture.A non-weaving cloth often needs could obtain higher intensity through multiple stage pinprick machine puncture.Trace it to its cause, because comparatively unfixing with the puncture position of pricker, acupuncture can not prick each position of whole non-weaving cloth, can only at fixing position puncture repeatedly, pricked the position arrived, no doubt form fiber and be entangled with, but, prick less than position be still loose state, even occur cracking or cut.So in order to make each position of whole non-weaving cloth can be arrived by puncture, just with the multiple row acupuncture puncture in turn that position offsets one from another, mutually making up cannot the position arrived of puncture.Hundreds and thousands of acupunctures are staggered installation of on needle-bar, and are aided with reciprocal puncture action at a high speed, till the intensity of non-weaving cloth reaches requirement.
As mentioned above, prior art can be arrived by puncture to make each position of whole non-weaving cloth, adopts acupuncture (needle-bar) puncture fast of a large amount of intervening portion, although this mode can make up the puncture blind area (position cannot arrived by puncture) between each acupuncture; But, the position of acupuncture is fixing after all, so, no matter repeat how many times puncture, the mechanical property of gained non-weaving cloth is not isotropism truly eventually, but only can show as isotropism among a small circle one, when investigating expanded range, its mechanical characteristics will transfer anisotropy to by isotropism, and this transition phenomenon is referred to as " counting mutation greatly ", and its isotropism mechanical characteristics interior is among a small circle referred to as " the same tropism in local ".
Local is actually the embodiment of prior art puncture technique with tropism's feature.No matter because the how intensive complexity of arrangement of existing pinprick technique needle-bar, it can be regarded as the superposition of multiple regular pricker behavior eventually, its result necessarily has rule and can say, just weakened due to number of samples little (namely Sampling Area is little) in this rule of a subrange, along with increasing (namely expanding Sampling Area) of sampling number, its regular increase, and then show anisotropic feature, namely there is the mutation of large number.Specifically, existing Nonwovens In Technology is difficult to obtained large-area isotropism cloth, and isotropism cloth product is the less cloth of area mainly.
In order to solve above-mentioned technical barrier, urgently research and develop a kind of Novel acupuncture device.In view of this, the present inventor, through creative thinking, proposes a kind of random point position pricker, to solve the problem.
Summary of the invention
The object of the present invention is to provide a kind of random point position pricker, fix to solve pricker puncture position, can only puncture fixed position, cannot the problem of pricker optional position randomly, and improve the local sex chromosome mosaicism in the same way of non-weaving cloth.
