Abstract

The utility model relates to a wire oscillator for a unitary drafting device, which comprises a wire leading device and a wire oscillating device. A front and a back wire leading plates are arranged in parallel to form the wire leading device, and a wire bundle passage is formed between the front and the back wire leading plates. The upper end of the wire bundle passage is a flat and straight passage, and the outlet of the lower end is a sine curve-shaped passage. The wire leading device is fixedly connected with a drafting device. A front and a back wire oscillating plates are arranged in parallel to form the wire oscillating device, and a wire bundle passage is formed between the front and the back wire oscillating plates. The upper end of the wire bundle passage is a flat and straight passage, and the outlet of the lower end is a sine curve-shaped passage. The wire oscillating device can move breadthwise, and is arranged below the wire leading device. The utility model can greatly enhance the transverse brute force of spunbonded nonwoven and reduce the difference of the longitudinal brute force and the transverse brute force.

Description

The used wire oscillator of whole extension apparatus

The utility model belongs to a kind of device that the direct Cheng Buzhong of melt spinning air drawing increases the non-weaving cloth cross force.

The air drawing that the production of spun-bond process non-weaving cloth is adopted is identical with the drawing-off principle that common chemical fibre is produced, and air drawing is to make it with its operation fiber to be attenuated with the frictional force between the tow by the high velocity air in the extension apparatus.High velocity air is being carried tow secretly and is being sprayed from extension apparatus, carries out lapping again.Lapping be by certain means make tow according to certain rules or mixed and disorderly lay to the one-tenth lace curtaining of lapper operation, form fibre web.

Extension apparatus roughly has three kinds of structures at present: 1, cis is arranged the slit extension apparatus more.Carry out air drawing along becoming the lace curtaining traffic direction that many row's slit extension apparatus are housed.For the horizontal brute force that increases non-weaving cloth with improve uniformity, be equipped with round roll-type pendulum wire device, utilize the next door effect of air-flow to carry out the pendulum wire lapping.2, tubular type extension apparatus.Above becoming lace curtaining many tubular type extension apparatus are installed laterally, it adopts pendulum formula pendulum wire device to break up lapping, to increase the uniformity of cloth.3, the whole extension apparatus of horizontal type.It mainly is that tow is evenly distributed in the horizontal that above-mentioned two kinds of extension apparatus adopt the purpose of pendulum wire device.Along with technological progress and scientific development, the appearance of the whole extension apparatus of horizontal type, the uniformity of cloth improves a lot.Wire oscillator also is not installed at present, so the horizontal brute force of cloth is lower.

The purpose of this utility model provides a kind of wire oscillator that increases the horizontal brute force of cloth.

The purpose of this utility model adopts following technical proposals to realize, that is:

The used wire oscillator of whole extension apparatus comprises fiber guiding device and pendulum wire device.Fiber guiding device by draw before be arrangeding in parallel filament plate and after draw filament plate and form, before draw filament plate and after to draw filament plate all fluted, forward and backward draw filament plate involutory after, formation～shape passage, be sinusoidal, bundle channel, fiber guiding device upper end passage inner edge is parallel shape linearly, fiber guiding device lower end passage inner edge is sine curve, and the fiber guiding device channel width is the flaring type.Fiber guiding device is installed on the extension apparatus outlet.The pendulum wire device is made up of forward swing filament plate that be arranged in parallel and back pendulum wire plate, and is all fluted on the forward and backward pendulum wire plate, after forward and backward pendulum wire plate is involutory, and formation～shape bundle channel.Pendulum wire device upper end passage inner edge is parallel shape linearly, and pendulum wire device outlet at bottom inner edge is sine curve, and channel width is gradual shrinkage.Pendulum wire device passage also can be flaring type or gradually-reducing-expanding type, but both sides of the edge, the narrowest place of passage should be sine curve.Pendulum wire device and fiber guiding device align setting up and down, and identical with the sinusoidal cycle of fiber guiding device, and amplitude is close.Pendulum wire device two ends are supported by the support of band slideway, and the one end is connected on the power set that have crank connecting link.

When high velocity air is being carried tow secretly from extension apparatus outlet ejection, enter fiber guiding device, fiber guiding device～type passage is laterally fixed tow, reduce horizontal looseness, identical shaped～type passage through the pendulum wire device clamps tow and teeter then, be taped against on the lace curtaining, the horizontal brute force and the uniformity of cloth are increased substantially.

The transverse strength that the utility model is simple in structure, easy for installation, can improve the spun-bond process woven cloths effectively.

Fig. 1 is the schematic appearance of a kind of embodiment of the present utility model, and Fig. 2 is the fiber guiding device vertical view, and Fig. 3 is the fiber guiding device upward view, and Fig. 4 is the vertical view of pendulum wire device, and Fig. 5 is the upward view of pendulum wire device.The utility model is described in further detail below in conjunction with accompanying drawing.

The used wire oscillator of whole extension apparatus comprises fiber guiding device 1, pendulum wire device 2, has the support 3 of slideway.Fiber guiding device by preceding draw filament plate 4, after draw filament plate 5 and form, preceding draw filament plate 4 and after draw filament plate 5 and be arranged in parallel, its two ends are fixed together.Before draw filament plate 4, after draw on filament plate 5 inwalls a plurality of grooves all arranged.Before draw filament plate 4 and after draw between the filament plate 5 and constitute bundle channel.This bundle channel upper end is straight shape passage 6, and its lower end outlet is sinusoidal passage 7.Bundle channel is vertical, is convergent shape from bottom to top.Fixedly connected with extension apparatus in the fiber guiding device two ends.The pendulum wire device is made up of the forward swing filament plate 8 that be arranged in parallel, back pendulum wire plate 9, on the inwall of forward swing filament plate 8, back pendulum wire plate 9 a plurality of grooves is arranged.After forward swing filament plate 8 and back pendulum wire plate 9 fasten, form bundle channel, the upper end of this bundle channel is straight shape path 10, and its lower end outlet is sinusoidal passage 11, and bundle channel is vertical, upwards is convergent shape.Fiber guiding device sinusoidal passage 7 is identical with the cycle of the sinusoidal passage 11 of pendulum wire device 2, and amplitude is close.Pendulum wire device 2 is vertically set on the below of fiber guiding device 1, and its two ends are placed in the slideway on the support 3.Pendulum wire device 2 is connected by the power set of connecting rod 12 with the band crank.
