Non-woven fabrics continuous needle structure
Art
The present invention relates to textile processing equipment field, especially, be a kind of continuous needle structure for nonwoven production.
Background technology
Needle punched non-woven fabrics is a kind of in dry non-woven cloth, be by chopped fiber through shredding, combing, be paved into fleece, so
After fleece is reinforced into cloth by pricker, pricker has hook to sting, and by fleece repeated localised puncture, hook strip is fiber reinforced, formed acupuncture
Non-woven fabrics.Produce non-woven fabrics with needle point method and be entirely the pricker puncture effect by a kind of mechanism, i.e. needing machine, by fluffy
Fibre web reinforce obvolvent and obtain strength.Ultimate principle is: utilize the pricker of triangle section seamed edge band barb to carry out fibre web instead
Multiple puncture.When barb is through fibre web, web surface and local nexine fiber are forced and thrust inside fibre web.Between fiber
Rubbing action, the most fluffy fibre web is compressed.When pricker exits fibre web, the fibre bundle barb that thrusts and stay fibre web
In, so, many fibre bundles tangle fibre web makes it can not recover original fluffy state again.Through acupuncture many times, phase
When many fibre bundles are pierced fibre web, make fiber in fibre web entangled to each other, thus formed and there is certain strength and the acupuncture of thickness
Method non-woven material.
Non-woven fabrics is punctured by traditional acupuncture mode by pricker repeatedly, and this mode is made due to motion mode back and forth
Becoming kinetic energy loss repeatedly, acupuncture speed is due to the restriction of mechanical strength simultaneously, and frequency can not be the highest.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of non-woven fabrics continuous needle structure, this non-woven fabrics
Continuous needle structure can the continuous needle non-woven fabrics of high-speed and energy-saving.
The technical solution adopted for the present invention to solve the technical problems is:
This non-woven fabrics continuous needle structure includes double end card wire and transmits the deflector roll of non-woven fabrics, the transport plane two of non-woven fabrics
Side is provided with at least one card wire circulation canal passing non-woven fabrics transport plane, and described card wire is circulated by non-woven fabrics transport plane
Channel segmentation composition from two parts, described card wire circulation canal inwall is provided with the induction coil of spiral extension, described double
The magnet arranged along axis it is provided with in comb pin.
As preferably, it is divided into the line of induction in the oral area of two-part described card wire circulation canal by non-woven fabrics transport plane
Circle number of turn density is more than two times of normal number of turn density.
As preferably, the oral area being divided into two-part described card wire circulation canal by non-woven fabrics transport plane is horn-like.
As preferably, between described card wire circulation canal, it is provided with magnetic masking layer.
It is an advantage of the current invention that:
Double end card wire in described magnetic induction coil energising rear drive card wire circulation canal, entering of described double end card wire circulation
Going out to be positioned at the card wire circulation canal of non-woven fabrics transport plane, the repeated puncture non-woven fabrics of circulation, described double end card wire is not owing to having
Shuttle motion but use the shuttling movement of annular, therefore kinetic energy loss is little, simultaneously can high-speed cruising, increase acupuncture
Frequency.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
In the present embodiment, refering to Fig. 1 and Fig. 2, this non-woven fabrics continuous needle structure includes double end card wire 400 and transmits nothing
Spinning the deflector roll 310,320 of cloth, the transport plane both sides of non-woven fabrics 10 are provided with at least one through non-woven fabrics 10 transport plane
Card wire circulation canal 110, described card wire circulation canal 110 is divided into two parts of separation by non-woven fabrics 10 transport plane, described
Card wire circulation canal 110 inwall is provided with the induction coil 200 of spiral extension, is provided with and institute in described double end card wire 400
State the magnet arranged along axis that induction coil 200 coordinates.
Above-mentioned non-woven fabrics continuous needle structure, is divided into the circulation of two-part described card wire by non-woven fabrics 10 transport plane logical
In the oral area in road 110 more than two times that induction coil 200 number of turn density is normal number of turn density, make described double end card wire 400
When puncturing non-woven fabrics 10 (around the most sensed coil 200 surround state), the line of induction at enhancing double end card wire 400 two
The magnetic induction of circle 200, makes double end card wire 400 be easier to penetrate non-woven fabrics 10.
Above-mentioned non-woven fabrics continuous needle structure, is divided into the circulation of two-part described card wire by non-woven fabrics 10 transport plane logical
The oral area in road 110 is horn-like, makes double end card wire 400 be easier to enter described card wire circulation canal 110, improves serious forgiveness.
Above-mentioned non-woven fabrics continuous needle structure, is provided with magnetic masking layer 120 between described card wire circulation canal 110, anti-
Only the magnetic field between each card wire circulation canal 110 produces interference.
The working method of above-mentioned non-woven fabrics continuous needle structure: the described magnetic induction coil 200 rear drive card wire that is energized follows
Double end card wire 400 in ring passage 110, the turnover of described double end card wire 400 circulation is positioned at the card wire of non-woven fabrics 10 transport plane
Circulation canal 110, the repeated puncture non-woven fabrics 10 of circulation.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included in protection scope of the present invention.
