Description
Technical field
The invention belongs to Personal hygiene field, relate to a kind of disposable sanitary product such as: sanitary towel, mistake
Prohibit pad, diaper etc., particularly relate to: the disposable sanitary products such as sanitary towel, incontinence pad, diaper
Absorbent cores uses Apparatus for () and method therefor prepared by mould wheel laminar flow, reaches disposable sanitary product absorbent cores tool
There is ultra-slim features, there is layering absorption, quick imbibition performance simultaneously.
Background technology
On market, existing disposable absorbent article is such as: the absorbent cores of sanitary towel, incontinence pad, diaper etc.,
Make after being added SAP (High hydrophilous resin) compacting by Time of Fluff Slurry, traditional absorbent cores processing technology
Being to be simultaneously introduced SAP and Time of Fluff Slurry in mould wheel cover, wherein SAP is that freely falling body mode enters mould wheel
In cover；Time of Fluff Slurry is to enter in mould wheel cover under the wind-force rotated at fiber uncoiling machine drives, the SAP in mould wheel cover
With Time of Fluff Slurry under the effect of external negative-pressure air fan, SAP is adsorbed in rotation with Time of Fluff Slurry simultaneously continuously
Mould wheel mould race in, the shortcoming of this technique is apparent from, such as:
In mould wheel cover, the mixing of the Time of Fluff Slurry that the SAP of freely falling body drives with wind-force is a kind of unordered mixed
Close, the SAP in mould wheel cover fail to be sufficiently mixed with Time of Fluff Slurry equably just by mould take turns negative-pressure adsorption at mould
In race, so the mixing of SAP and Time of Fluff Slurry is uneven.
Unordered mixed SAP and Time of Fluff Slurry are in mould race, by the negative-pressure air fan absorption within mould wheel,
Having more SAP and be sucked away from mould race by negative pressure, on the one hand this situation can make the SAP stream in absorbent cores
Lose, affect the imbibition ability of absorbent cores, make the absorbent cores quality after production uncontrollable simultaneously, another
Aspect: this phenomenon also results in absorbent cores and produces the significant wastage of material, namely a kind of natural resources
Significant wastage.
The SAP of unordered mixing and Time of Fluff Slurry, often occur that SAP piles up, and the phenomenon such as Time of Fluff Slurry conglomeration,
The absorbent cores being finally made, it may appear that absorbent cores lump is many, and product does not has the defects such as comfort level, seriously
Affect the use function of product.
As it has been described above, limited by unordered hybrid technique, in existing absorbent cores, the adding proportion of SAP is all
Less, if improving the most merely SAP addition, and SAP and the fine hair of addition can not be made
Slurry is sufficiently mixed, and absorbent cores product there will be degradation absorbent cores under layering, pliability cannot service condition.
So in the case of requiring that absorbent cores is frivolous, such as the imbibition ability of absorbent cores to be increased, it is necessary to assure
Absorbent cores is added a high proportion of SAP and is sufficiently mixed.
Above-mentioned situation often occurs in absorbent cores manufacturing process, and makes absorbent cores hydraulic performance decline,
Natural resources is caused significant wastage simultaneously, by changing the processing technology of absorbent cores, simultaneously improve mould
The structure of wheel, so that absorbent cores i.e. ensures that absorbent cores is frivolous, keeps absorbent cores quick imbibition simultaneously
Characteristic, this is the major issue that the invention solves the problems that.
Summary of the invention
The invention belongs to Personal hygiene field, relate to a kind of disposable sanitary product such as: sanitary towel, mistake
Prohibit pad, diaper etc., particularly relate to: the disposable sanitary products such as sanitary towel, incontinence pad, diaper
The laminar flow preparation method of absorbent cores, makes disposable sanitary product absorbent cores have ultra-slim features, has simultaneously
There are layering absorption, quick imbibition performance.
This technology solve SAP and Time of Fluff Slurry can not a well-mixed difficult problem, fundamentally solving simultaneously:
During mould wheel joins the absorbent cores of sanitary towel, incontinence pad, diaper etc. with transfer wheel, the unrestrained of SAP is asked
Topic.
The present invention need solve first problem be: the SAP in die cavity can not equably with Time of Fluff Slurry
It is sufficiently mixed.Know from prior art: in the unit interval, producing the feelings that the board speed of service is constant
Under condition, after fiber uncoiling machine solution fibre, the Time of Fluff Slurry unit mass entering mould wheel is constant, in mould wheel
Exist again negative pressure, SAP and Time of Fluff Slurry be all by mould wheel die cavity in negative-pressure adsorption mould wheel die cavity in
, mould wheel die cavity gradually adsorbs SAP and Time of Fluff Slurry in rotation.Can exist by controlling SAP
Traffic direction in die cavity and speed, in mould wheel cover, specific position is filled with high-speed compressed air, high
Carrying SAP in speed compressed air, and make airflow direction controlled, the high-speed compressed air being filled with is taken turns at mould
Laminar flow is formed at cover top, and this laminar flow is by forming tumble mixed gas after vacuum suction in mould wheel in laminar flow bottom
Stream, SAP and Time of Fluff Slurry tumble mixed in tumble mixed air-flow, reach SAP and mix in order with Time of Fluff Slurry
The purpose closed.In mould wheel cover, specific position is filled with high-speed compressed air and can control in the unit interval
The SAP paving amount of spilling in mould wheel die cavity and position, thus also just control the mixing of SAP and Time of Fluff Slurry
State and ratio.A device is designed, by the SAP operation side within this device for this present invention
To just can be controlled；Adjustable compressed air it is filled with, inside this device in this device
SAP speed can also be controlled, this addresses the problem SAP can not be sufficiently mixed with Time of Fluff Slurry equably
Problem.
The present invention need solve Second Problem be: the SAP of uneven mixing is often deposited on mould
Bottom wheel mold cavity, when mould wheel and the absorbent cores of transfer wheel handing-over sanitary towel, incontinence pad, diaper etc.,
It is deposited on the SAP bottom mould wheel mold cavity can not shift completely, it will usually trickle down at mould wheel and transfer wheel
Seam crossing, thus cause the decline of the imbibition ability of the absorbent cores of sanitary towel, incontinence pad, diaper etc..
Experiment proves that mixed uniformly SAP also has a small amount of SAP and deposits under the effect of negative pressure in mould wheel mold cavity
Bottom mould wheel mold cavity, for this, we devise a division board at mould wheel intracavity, and this division board can
With by Time of Fluff Slurry and isolate SAP simultaneously, first pass through negative in mould wheel die cavity of the Time of Fluff Slurry of division board
Under pressure adsorption, first adsorb in mould wheel die cavity, the most just absorption SAP and the mixing of Time of Fluff Slurry
Thing, say, that: at SAP before by mould wheel die cavity absorption, there is one layer of Time of Fluff Slurry firmly to inhale
It is attached to bottom mould wheel die cavity, when the suction of mould wheel with transfer wheel handing-over sanitary towel, incontinence pad, diaper etc.
When receiving core, SAP also would not be had to spill.
Traditional handicraft is directly to add the mode that SAP, SAP are freely falling bodies in mould wheel cover to enter mould
Wheel cover, this technology changes to: is carried SAP by high-speed compressed air and enters in mould wheel cover, its operation side
To being to there is specific angle direction and can regulate, it is therefore an objective to: due to the injection of high-speed compressed air,
A new laminar flow is formed in mould wheel cover, after this laminar flow crosses with original negative-pressure air-flow in mould wheel,
Form a tumble mixed air-flow in laminar flow bottom, the SAP of high-speed cruising and Time of Fluff Slurry are in tumble mixed
Under airflow function, produce between centers and move and rolled and uniformly mix, through mixed uniformly SAP with
Time of Fluff Slurry is under the continuous adsorption of negative pressure that mould is taken turns, then is adsorbed in mould wheel.In this technology makes mould wheel cover
Air-flow become laminar flow, tumble mixed air-flow, negative-pressure adsorption 3 from the negative-pressure adsorption air-flow of traditional handicraft
