When in use, the yarn separating device is installed between the outlet of an air spinning channel and a fiber collecting device, the front yarn guide plate is positioned at a yarn outlet of a drawing apparatus, one yarn extending out of the drawing apparatus is divided into two yarns at equal interval in relation to the machine operating direction under the guide of a specific air guide device by using the inherent process air flow in the air flow drawing process, so that the yarn falling area is expanded on a web former, the density difference is reduced, and the evenness of the web placement is improved.
Description
Technical field
[0001] the utility model relates to a kind of branch silk device of spun-bond process non-weaving cloth, is applicable to the spun-bond process non-weaving cloth production line that adopts rectangle malleation air-flow extension apparatus.
Background technology
At present mainly contain the negative pressure drawing-off in the production of spun-bond process non-weaving cloth, the tubular type malleation is stretched oneself and yawn and the different drawing-off mode of rectangle malleation drawing-off three classes.The draft speed of rectangle malleation drawing-off improves easily, favourable raising Production Line efficient, and simultaneously some being needed the higher polymer of draft speed then is to have to use.But use rectangle malleation extension apparatus because the muzzle velocity of air-flow and silk is all very high, and the area that falls on lapper is less, the lay uniformity that makes fibre web is not as the negative pressure draft process.Improve its lapping uniformity is one of target of nonwoven fabric industry technology personnel effort always.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of branch silk device of spun-bond process non-weaving cloth is provided, and it can be with the more uniform lay of fiber that comes out in the rectangle malleation air-flow extension apparatus to collecting on the lace curtaining.
The technical scheme that the utility model adopted is: a kind of branch silk device of spun-bond process non-weaving cloth, comprise branch silk device, described branch silk device is made up of two preceding thread plates that form an angle and back thread plate, the traffic direction of thread plate upper edge silk has the equally spaced trapezoidal groove that falls before described, and described back thread plate is dull and stereotyped or has and the staggered rectangular through slot of the trapezoidal groove of falling of preceding thread plate along the traffic direction of silk.The angle of preceding thread plate and back thread plate is generally 8 °-20 °.
Well-behaved silk device is installed between the outlet and fiber collecting device of rotor spinning passage during use, preceding thread plate is positioned at the filament mouth of tractor, and the width of thread plate can splice, and its overall width equals or be slightly larger than the width of slinning cabinet (extension apparatus outlet).
The beneficial effects of the utility model: the branch silk device that adopts said structure, utilize intrinsic process gas flow in the air drawing technology, under specific airflow guiding device guiding, can earlier the equally spaced relative machine run direction of one " sheet " silk of coming out in the extension apparatus be divided into two, thereby enlarge the fall thread area of silk on lapper, this moment, every silk presented equally spaced density state in vertical machine run direction.Further the silk in each sheet reduces density difference in the diffusion of the effect lower edge of air pressure cross machine under the effect of airflow guiding device, finally drops on and collects on the lace curtaining.Its effect is equivalent to have two extension apparatus one in front and one in back to spread silk simultaneously along the machine run direction, thereby has improved the uniformity of lapping.
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
Description of drawings
Fig. 1 adopts the utility model to divide the spinning equipment the Silk Road schematic diagram of silk device.
Fig. 2 is that the utility model divides a kind of embodiment of silk device the wherein stereogram of one section branch silk device (plate).
Fig. 3 is that the A of Fig. 2 is to view.
Fig. 4 is that 2 B is to view.
Fig. 5 is that 2 C divides silk to pull view forward.
Fig. 6 is that 2 C divides silk to pull view backward.
Drawing explanation: the 1. silk sheet of a formation, 2. air-flow tractor, 3. minute silk device, 4, silk sheet and air-flow, 5. preceding branch silk is pulled, and 6. the back divides silk to pull, and 7. falls trapezoidal groove (abcd), 8. rectangular through slot (a ' b ' c ' d ') is 9. installed and is pulled, the angle of thread plate and back thread plate before the g..
The specific embodiment
As Fig. 2, Fig. 3, Fig. 4, Fig. 5, embodiment illustrated in fig. 6, one's duty silk device 3 is made up of preceding thread plate 5 and the back thread plate 6 of two g that form an angle, and both angle g are generally 8 °-20 °.It is trapezoidal abcd among Fig. 5 that the traffic direction of described preceding thread plate 5 upper edge silks has the equally spaced trapezoidal groove 7(of falling), promptly near slinning cabinet end is wide, and the traffic direction of edge silk narrows down.Described back thread plate 6 be dull and stereotyped or along the traffic direction of silk have with the trapezoidal groove 7 staggered rectangular through slot 8(of falling of preceding thread plate be rectangle a ' b ' c ' d ' among Fig. 6), present embodiment adopts the back thread plate that is provided with rectangular through slot 8, promptly as shown in Figure 6, flat c ' d ' e ' f ' that pulls equidistantly forms continuously with rectangular through slot a ' b ' c ' d ' is staggered by some rectangles, divides a silk effect with further raising.The width of wire sub-panel can splice, and its overall width (promptly dividing silk device width) equals or be slightly larger than the width of slinning cabinet (extension apparatus outlet).Hem width ad greater than trapezoidal groove is divided a hem width d ＇ e ＇ of the rectangular slab of pulling in the back.
During installation, the back is divided the perpendicular bisector on the c ＇ f ＇ limit that silk pulls 6 rectangular flat and preceding branch silk to pull 5 the perpendicular bisector on ad limit of dovetail groove 7 of falling to overlap, harden on the zygonema two, the ad limit of trapezoidal groove of falling on the preceding wire sub-panel is dropped on the back fully and is divided in the rectangular slab that silk pulls (d ＇ e ＇＞ad).Branch silk device 3 after the assembly unit is pulled 9 by the installation on it and is fixed on the tractor below, and preceding thread plate is positioned at the filament mouth of tractor.
When air-flow clamping silk arrives the extension apparatus outlet,, force silk to be affixed to wire sub-panel because the effect of entrainmenting of jet forms a low-pressure area between silk sheet and wire sub-panel.Silk before dropping in the wire sub-panel de zone will continue descending along preceding wire sub-panel, and the minimum pressure area of Si Zeyin before dropping in the wire sub-panel ad zone is to be forced to be affixed to the back wire sub-panel at wire sub-panel d ＇ e ＇ place, back, and continues descending along the back wire sub-panel.Thereby, from the silk sheet of extension apparatus ejection air-flow and divide under the acting in conjunction of silk device by continuously, at interval be divided into two, divide silk sheet whereabouts along preceding branchs silk sheet and back separately.Because of air-flow is also cut apart by a minute silk device, the de section has high velocity air and silk on preceding branch silk sheet, and the ab section does not have, and also can the distribution of silk in the every silk be tended to evenly along the width diffusion of minute silk device at air-flow and silk from ad end diffusion tow with air-flow when the cf section is mobile.
