Spun-bond process is also known as filature fleece formation method, it is most important in non-woven cloth, a kind of most widely used method.It is benefit
With synthetic fiber spinning principle, lay networking using continuity filament fiber during polymer spinning, fibre web through mechanical, chemistry or
Hot method, which is reinforced, forms non-woven cloth.Its detailed process is as follows:
It after hopper is added in polymer chips, is fed into screw extruder, screw rod has heating function, is sliced in screw rod
It melts and squeezes out, melt after filtering is transported on filament spinning component by metering pump by certain flow, and filament spinning component is equipped with very much
The spinneret of aperture, melt are flowed out out of spinneret aperture, form many threads, melt stream after side-blown air cooling,
It is cooled to fiber, enters back into drafting system, is acted on by the drawing-off of the high-speed flow in drafting system, the macromolecular of fiber carries out
Orientation and crystallization, fiber obtain good mechanical property, and after drawing-off fiber lay down enters to the following networking for having air intake device
On curtain band, it is then sent to bracing means, hot rolling, chemical adhesion, needle thorn, spun lacing etc. are any or two methods are reinforced,
Become filature fleece formation non-woven cloth.
Wherein, cross air blasting directly affects the crystallinity and mechanical property of fiber to the cooling situation of melt stream.Cross air blasting
Wind-warm syndrome, wind speed and cross air blasting height determine the quality of cooling effect.
The disadvantage is that:
Since in actual production, due to the variation of product specification, the fiber number (thickness) of fiber also has bigger change
Change.Its requirement to the blowing height of cross air blasting of the fiber of different fiber numbers is different.Thin fiber is cooling to be easy, it is therefore desirable to
Cross air blasting blowing height it is shorter；Thick fiber cooling difficulty, thus the blowing height of the cross air blasting needed is longer.But mesh
Its height of drying of preceding cross air blowing device is to immobilize, and is not adjustable.Therefore, thin fiber, blowing height are being produced
It is too long, it causes to waste, and producing in thick fiber, blowing height is too short, be easy to cause fiber cooling inadequate.
Utility model content
The shortcomings that the utility model is overcome in the prior art provides a kind of height-adjustable spunbonded nonwoven cross air blasting
Device can ensure that the Investigation of Optimum Cooling Condition of fiber, improve production according to its blowing height of the thickness de-regulation of fiber
The quality of stability and product improves production stability, improves the performance of fiber, reduces waste.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
A kind of height-adjustable spunbonded nonwoven cross air blowing device, including air duct, the air duct include roof and two sides
Wall, the lower part in the air duct are a pressing plate, and the middle part of the pressing plate is equipped with hinged supporting means, and one end of the pressing plate is resisted against
Above winding device, the one end of the pressing plate far from the winding device is air inlet, the winding device by membrane body wound on
Formed on wireline reel, the wireline reel by can the first motor of positive and negative rotation drive rotation, to generate winding and backing off, the film
One end that body is stretched out to outside the winding device connects slide-bar, and the slide-bar is located in vertical chute, and the vertical chute is located at
Air opening end, the air opening end are equipped with strainer on the outside of the sliding slot.
Further, the lower part of the roof is equipped with aerofoil, and the aerofoil is swung by the second motor driven.
Further, Cellular Networks are equipped between the strainer and sliding slot.
Further, the membrane body is plastic foil.
Further, the slide-bar also stretches out horizontal wind deflector.
Compared with prior art, the utility model has the beneficial effects that
The utility model realizes the controllability of blowing height, this is to make plastics film length by the restriction effect of sliding slot
Change transitions at slide-bar height variation, thus realize blowing height variation.
