Description
Technical field
The present invention relates to air-laying technique field, particularly relate to the thin net air lay equipment of a kind of twice molding.
Background technology
Random web-laying equipment be exactly by by front road through the fiber of preliminary shredding, utilize aerodynamic principle, defeated by air stream
Sending fiber, making fiber is that unordered atactic uniformly fleece delivers to defeated lace curtaining, then is given the arrangement in rear road by defeated lace curtaining and set
Standby, conveniently it is directly prepared into non-weaving cloth.This technology instead of traditional traditional machine as representative with carding machine and cross lapping machine
Tool production technology, is developed rapidly, such as the nineties in 20th century in the world: Le K12 random web-laying equipment, U.S. orchid are taken in Austria
The random web-laying equipment of many companies, Austria the DOA random web-laying equipment of DOA company, U.S.'s Procktor. the PS air-flow of assorted Watts becomes
Net machine etc., the domestic random web-laying equipment also having design, is installed additional by Shanghai City Spinning Science Institute the beginning of the sixties on carding machine
Air-flow conveying, one-tenth net absorption etc..
The product that random web-laying equipment produces, fiber alignment is non-directional, and the vertical, horizontal intensity of product is of substantially equal, product
Soft, fluffy, compared with traditional non-weaving cloth, the thickness of the goods of same fiber consumption improves many, and product has well
Elasticity and breathability.Production process does not use lapping machine, and the speed of production of whole production line is greatly improved.Air-laid process
The special fibre (such as carbon fiber, glass fibre, ceramic fibre) bigger to fragility and higher fiber (metallic fiber, the fiber crops of hardness
Fiber) net can be processed into, solve traditional handicraft after combing, lapping, then through acupuncture, the difficult problem that fleece ruptures.
The random web-laying equipment of patent disclosure has the double dust cage gas of Yizheng Hairun Textile Machinery Co., Ltd., Jiangsu Prov. at present
Stream lapper CN 102505204A and random web-laying equipment CN 102373516 A of Yingyang Non-Woven Machinery Co., Ltd., Jiangsu.Double
Dust cage random web-laying equipment, solves mono-dust shroud random web-laying equipment and yields poorly, improve production production capacity, meets sun nonwoven Machine Design
Random web-laying equipment, is by the fiber through shredding, through being arranged on before cylinder two rollers, roller and Bearded-needle knitted cloth crown phase
Right, opposite direction rotating, the centrifugal force that high rotating speed produces makes the fiber of mixed and disorderly surface of roller become being suspended in stannum from tensioning straight condition
Relaxed state on woods card clothing tooth top, fiber is randomly distributed in cylinder, by air exhauster by web through air channel, fiber lapping is turned
Turning to finished product, convulsion uses bottom drawing, reduces web output resistance, improves into net spee and stops the blocking of passage web now
As.
, there is following defect in above-mentioned random web-laying equipment:
A, Double-dust-cage air laying machine are only applicable to the product producing grammes per square metre at 4000~6000g/m2 thicker stratum reticulares, equal to product
Evenness requires relatively low, is not suitable for the product producing ultrathin grammes per square metre 60~100g/m2, uniformity requirements is high.
The random web-laying equipment of B, Ying Yang company design, though having made air draft mechanism to improve, but controls also web uniformity
Existing problems, and before fiber enters cylinder, use a pair roller transfer fiber, roller is cylindrical roller, deposits between two rollers
In certain space, fiber easily falls between two roller spaces, and after cylinder runs up certain time, interstitial fiber knot is poly-
When measuring many, fiber balling on cylinder, pockets of fiber is caused to enter into wet end with air-flow, cause into net uneven, affect product
Quality.
Random web-laying equipment key technology is that by airflow blow and suction, the relaxed state fiber on Bearded-needle knitted cloth crown is become net, for
Ensure that air-flow is uniform, use the principle of Venturi effect, air-flow from the coarse to fine, to accelerate gas flow rate, make gas Wen
The rear side of pipe outlet forms " vacuum " district.Cross section is gradually reduced, and compressed-air actuated pressure reduces, and flow velocity becomes big, causes week
Enclosing fiber to be inhaled in Venturi tube, the compressed air of band fiber becomes net along with induced-draught fan enters lapping curtain together.Venturi tube is led to
Cross volume-diminished, become larger, do not make gas flow optimized, air motion direction and the friendship becoming lace curtaining (or dust cage) cohesion face in pipeline
Angle is big, then fiber easily pours mesh, forms coma, causes into net and attracts the disorder of air-flow, brings the uniform of fleece, the most just
The uniform of slim stratum reticulare cannot be ensured.
