Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Referring to Fig. 1, the paper machine 100 of the present invention one better embodiment, it includes that one is single
The forming section 20, one that the head box 10 of layer is connected with this head box 10 is dehydrated device 40
And a sound wave controlled device 60.This forming section 20 include a forming face 22 and with forming face 22
Opposing outer surface 24.Described dehydration device 40 adjoins described outer surface 24 and arranges.
In the present embodiment, this forming section 20 is long mesh paper making machine forming section.It should be understood that root
According to being actually needed, this forming section 20 can be also the paper machine that the other types such as folder net forming section shape
Forming section.It should be understood that according to actual needs, this dehydration device 40 can be schemed incessantly
One shown, can arrange multiple.
Described sound wave controlled device 60 can send acoustic wave action fiber in slurry.Due to sound
Ripple is relevant with the size of fiber (such as length, diameter etc.) to the size of the active force of fiber, as
The fiber stress that the fiber stress of thick length is short greatly and carefully is little, and such sound wave controlled device 60 can root
Size and thickness according to fiber carry out AUTOMATIC ZONING process to the fiber in slurry.This sound wave control
Device 60 processed includes sonic generator 62 and acoustic receiver 64.This sonic generator 62
Neighbouring described forming face 22 is arranged.This acoustic receiver 64 is arranged adjacent to described outer surface 24,
So that the sound wave that sonic generator 62 is launched can be through spraying from head box 10 and flowing to
The slurry of forming section 20, is then received by acoustic receiver 64.This sound wave controlled device 60
It is preferably ultrasound wave and controls device.It is preferred that in the present embodiment, described sonic generator 62
It is perpendicular to described forming section 20 with the line of acoustic receiver 64.Namely described sound wave occurs
The sound wave that device 62 sends is perpendicular to this forming section 20 to the direction of the active force of slurry.
It is preferred that the direction that the sound wave that sends of described sonic generator 62 is to the active force of fiber
It is perpendicular to this forming section 20, so can improve the efficiency that fiber AUTOMATIC ZONING processes.
It is preferred that described sound wave controlled device 60 to be positioned adjacent to described forming section 20 close
One end of described head box 10 so that slurry in time having just enter into forming section 20 at sound wave
It is layered under effect, improves the work efficiency of this paper machine 100.
During applying this paper machine 100 to carry out papermaking, it is filled with in this head box 10
The slurry of the suspension of flowing.This slurry flows out along the direction of arrow a from head box 10, and
The relative other end is flowed to by one end of forming section 20.This slurry includes size different
At least two fiber, such as long fibre and chopped fiber, described long fibre, chopped fiber random distribution
In the slurry.This sonic generator 62 launches the sound wave direction along arrow b through suspension
Slurry points to described acoustic receiver 64.The direction of transfer of this sound wave and the direction of pulp flow
Vertically.Under the thrust of sound wave, slurry medium-length fibre is because of the thrust of sound wave that is subject to relatively
Ambassador its along the direction (i.e. the direction of arrow c) of arrow a and arrow b synthesis towards shaping
The outer surface direction in portion 20 is moved, and is gradually deposited in forming section 20, and chopped fiber
Fiber is because of less and be suspended in long stapled top by the thrust of sound wave.So, at slurry
Size difference fiber AUTOMATIC ZONING under the effect of sound wave in flow process, in slurry.
The present invention provides the method for this paper machine papermaking of an application, mainly comprises the steps:
Described paper machine 100 is provided.
The slurry being used in the suspension shaping paper sprays from head box 10, and by forming section
One end of 20 flows to the relative other end.This slurry includes at least two that size is different
Fiber, such as long fibre and chopped fiber, described long fibre, chopped fiber random distribution are in the slurry.
Open described sound wave controlled device 60, under the effect of sound wave, size and thick in slurry
The fiber carefully differed is in flow process AUTOMATIC ZONING.Owing to the thrust of sound wave is consequently exerted at slurry
On the erose fiber of middle tool, during fiber deposits, fiber itself also can
Occur spinning to reduce the thrust by sound wave, make few fibers be approximately perpendicular to forming section
20, thus improve the thickness of paper and looseness prepared through the method, improve the suction of paper
Fluidity energy, and improve the Surface feel of paper.
Use described dehydration device 40 that the slurry of above-mentioned layering is carried out processed.Due to
Forming part 20 forming face 22 direction deposition be long fibre rather than chopped fiber is (long stapled
The relatively chopped fiber that interweaves is loosened), and few fibers is approximately perpendicular to forming section 20, make fiber it
Between intertexture the most loose, the long fibre precipitation to forming net 20 direction makes free water in slurry
It is prone to be removed through forming net 20, and then improves the dewatering speed of slurry.And because
Chopped fiber and fiber fines deposit to be dehydrated and easily block net blanket on the net blanket of device, and this
Long stapled deposition after bright layering, so the blocking of net blanket can be reduced, and then improves described paper
Open the production efficiency of manufacturing process.
Dehydration disposed slurry is carried out drying and processing, i.e. prepares required paper.This paper includes
At least two fibrous layers, each described fibrous layer is mainly made up of various sizes of fiber.
Refer to Fig. 2, a kind of by the paper obtained by said method.This paper includes at least
Two fibrous layers, each described fibrous layer is mainly made up of various sizes of fiber.The present embodiment
In, described paper 200 includes one first fibrous layer 220 and is laminated in the first fibrous layer 220
On the second fibrous layer 240.The described first main long fibre of fibrous layer 220 is interwoven.
Described second fibrous layer 240 is mainly interwoven by chopped fiber.
Compared with prior art, the present invention without using multilamellar or multiple head box, only with
Sound wave controlled device 60 and single-layer headboxes 10 i.e. can reach make in slurry various sizes of
The effect that fiber such as long fibre and chopped fiber are layered effectively, reduces sheet formation work
The equipment cost of skill, energy consumption, shorten the length of forming section 20, greatly reduce described in make
Paper machine 100 is taken up space.Further, since during sheet formation, long fibre is near becoming
The direction deposition in shape portion 20, improves the water filtering performance of forming section 20, improves paper machine
100 work efficiencies；The paper 200 prepared by the method also can be made to have high thickness and height
Absorbency.
It addition, those skilled in the art also can be in the claims in the present invention scope of disclosure and essence
Make the various amendments in other form and details in god, add and replace.Certainly, these depend on
The various amendments made according to present invention spirit, add and the change such as replacement, all should be included in this
Invent within the scope of claimed.
