Description
Technical field
The invention belongs to field of non-weaving textile machinery technology, and in particular to a kind of cotton feeding device of random web-laying equipment.
Background technology
The function of random web-laying equipment is by by the on-woven fiber shape after the fibre-opening unit of preceding working procedure i.e. opener
Into web, and it is delivered to the modular system in rear road and is shaped into such as non-woven fabrics, insulation material, deadening felt, automotive upholstery, family
Occupy bedding supplies（Such as back cushion）Etc product.Foregoing modular system such as needing machine and spun-laced machine.
From the foregoing, random web-laying equipment is set on complete on-woven production streamline in fibre-opening unit with sizing
Between standby.Random web-laying equipment is that the cotton carding roller rotated while comb divide to on-woven fiber using high speed makes on-woven fine
Dimension is dispersed in airflow field and makes on-woven fiber be in distributed in three dimensions state, that is, forms substantially omnidirectional（No yield point）State.
Have due to airlaid to fiber wide adaptability（For example suitable for polypropylene fiber, terylen fiber, flaxen fiber, natural fiber with
Various composite fibre that chemical fibre is mixed, etc.）And the fiber number of fiber can length into the net from more than 15d-30d
Place, thus be widely used in the production of on-woven product.
As complete random web-laying equipment, generally it is made up of lower three parts：One is cotton feeding device, for receiving by preceding road work
The on-woven fiber inputted after the opener of sequence and by the cotton transport curtain of opener, the core component of the cotton feeding device is comb
Cotton roller, its surface is provided with pin cloth, is taken by cotton carding roller comb and comes from the cotton transport curtain i.e. on-woven fiber of opening fiber convoying curtain；Two are
Consolidation means, its core component is cotton roller（Industry custom claims dust cage）, the effect for preventing web elegant is played by cotton roller；Three
It is web forming device, the web forming device corresponds to the lower section of foregoing consolidation means, and its core component is cotton transport curtain, will by cotton transport curtain
The on-woven fiber web for coming from the cotton output port of cotton-entering channel is exported under the synergy of cotton roller, and the shaping in road is set after supply
Standby shaping.
In airlaid, the quality of the thickness uniformity of the cellucotton stratum reticulare exported after web forming device networking is depended on
Cotton feeding device, this is industry early established common recognition.Equally, whether the grammes per square metre of on-woven product is consistent also close with cotton feeding device
It is related.It follows that being satisfied the on-woven product of the desired degree of consistency of industry to obtain grammes per square metre, then must be by
Cotton feeding device rational in infrastructure is pre- with guarantee.
It can be seen in disclosed Chinese patent literature and be intended to improve cellucotton net thickness uniformity to expect to make on-woven
The consistent technical information of the grammes per square metre of product, such as CN2663451Y recommends have " the improved cotton feeder of structure ", and the patent formula can have
The air in on-woven fiber is displaced on effect ground（Using lateral negative-pressure ward）, make the web led on cotton transport curtain closely knit, it is to avoid
Excessively fluffy situation is produced, to improve the thickness uniformity of web.The patent formula is except its specification final stage of page 1
Also there is the terse strong point of structure outside technique effect.In addition with such as CN2091877U（1.5 meters of breadth degree chemical fibre acupuncture nonwoven felts
Random web-laying equipment）、CN2818508Y（A kind of random web-laying equipment for being used to produce non-woven fabrics）、CN201212072Y（Production industry
With the random web-laying equipment of felt）、CN201406502Y（Airlaid output fiber networking sub-controlling unit）、CN101845712A
（The negative suction system of random web-laying equipment）、CN203834132U（Random web-laying equipment）And CN104514093A（It is airlaid
Machine）, etc..
Typical " lapper of air-flowing type lapper " provided such as invention patent mandate notification number CN102505202B
" random web-laying equipment " introduced with CN102373516B.By taking CN102373516B as an example, it is deposited for foregoing CN2663451Y
Deficiency and propose, for details, reference can be made to the 0003rd to 0004 section of the specification and 0020- of the CN102373516B
0035 section.
It is not limited to all patents exemplified above and patent application scheme and does not provide possess how cotton feeding device to change
The technical inspiration of the even scattered effect of kind fiber, that is to say, that only make fiber is fully even to dissipate by means of air-flow, on-woven could be ensured
The Forming Quality of product.By taking foregoing CN2663451Y and CN102373516B as an example, due to being by dust cage i.e. cotton roller
Suction the thickness of cellucotton stratum reticulare is tended to be uniform, thus substantially a kind of measure controlled table rather than effected a permanent cure because
Fiber it is even dissipate it is not sufficiently effective with embodiment on the premise of the simple suction by subsequent work stations do not realize cellucotton stratum reticulare really
Grammes per square metre is consistent.
It is that this applicant has made lasting and beneficial exploration with setting for above-mentioned prior art, it is necessary to improved
Meter, forms technical scheme described below, and deduce examination through computer simulation in the case where taking secrecy provision finally
Test, be as a result proved to be practicable.
The content of the invention
The task of the present invention is to provide a kind of even scattered property for helping to significantly improve fiber and use guarantee by rear road
The grammes per square metre of the cellucotton stratum reticulare of web forming device formation is consistent and random web-laying equipment of ultimate guarantee on-woven product quality gives cotton
Device.
