(running action)
Below, the running action of this artificial cotton manufacturing installation 1 is described.
At first, at material feed mechanism 50, PTFE fiber, ETFE fiber or a plurality of fibrous materials 2 that contain these fibers and other fibers are supplied to roller unit 10 from each bobbin 51 by guide roller 52,53 and niproll 54,55.Fibrous material 2 is pressed in the housing 11 from the supply port 11a of housing 11, by flowing to outlet 11b between lower house 11d and the faller gill roller 12.
This staple fibre 3 is blown out in the wind-tunnel 30.By the forced exhaust of exhaust gear 60, the inside of wind-tunnel 30 produces downward air flow, and described staple fibre 3 accumulates in the surface of inserting paper 20 simultaneously along with this air flow disperses in wind-tunnel 30.
Herein, staple fibre agitating plate 32 is that main channel, front plate 30a side (roller unit 10 sides) are subaisle with backplate 30b side relatively, from the chokes part of wind-tunnel 30 top inhaled airs by the both sides of main channel and subaisle.And, because air is necessarily by two place's chokes parts, so the negative pressure in its downstream is bigger than in the past, in the stronger injection stream of outlet generation of chokes part.The interaction of the injection stream that utilization produces at two places is evenly stirred staple fibre 3 in wind-tunnel 30.It is also relevant with following situation to produce strong injection stream, that is, the air flow that eddy current forms plate 34 and subaisle intersects turns round air flow, eddy current form between plate 34 and the roller unit 10 the flowing resistance change greatly.
And, in the downstream of the chokes of subaisle side part, shown in the air flow that Fig. 8 represents, by blow blow out air and produce eddy current of the faller gill roller 12 by rotation at a high speed from the effect of the injection stream of this chokes part.This eddy current forms the below of plate 34 and moves along baseplate part 33 circulations from eddy current, very fast and merge from the air flow of subaisle.Therefore, air can side not be detained below eddy current forms plate 34 and baseplate part 33, so staple fibre 3 can not be detained yet, can not produce problems such as staple fibre 3 adheres to.In addition, utilize the mixing effect that produces by eddy current, staple fibre 3 is uniformly dispersed in wind-tunnel 30.
In addition, produce blow out air upwards, but as previously described, owing to partly produce strong injection stream from the chokes of subaisle, staple fibre 3 can not be blown out to the machine outside because of ascending air at the outlet 11b of roller unit 10.
Like this, a plurality of staple fibres 3 that disperse in wind-tunnel 30 are along with air flow is transferred, and tangle mutually, assemble arriving also to receive when inserting paper 20 surperficial from the effect of the attraction of exhaust gear 60.And, when slotting paper 20 flows to work beam 70 from inserting paper bowl 21, accumulate in slotting paper 20 lip-deep staple fibres 3 and push by niproll 41, form artificial cotton.In addition, also can heat when roller 41 is pushed being held, make staple fibre bonded to one another.In addition, the artificial cotton of manufacturing will be inserted paper in use and peel off the back use.
(effect of embodiment)
The downside end 33a of baseplate part 33 that is configured to make staple fibre agitating plate 32 in this embodiment is near the backplate 30b of wind-tunnel 30, eddy current forms the front end 34a of plate 33 near roller unit 10, when air is by two place's chokes parts, air flow turns round in the subaisle side, thereby improve the negative pressure in the wind-tunnel 30, the chokes separately of main channel and subaisle part go out the strong injection stream of interruption-forming, so can utilize the interaction of two place's injection streams evenly to stir staple fibre 3.Therefore, can suppress the deviation (skew) of the staple fibre 3 in the wind-tunnel 30, can manufacturer's area on the artificial cotton of weight unanimity.
In addition,, utilize the eddy current that produces by effect from the discharge air of roller unit 10 and described injection stream in the subaisle side, can prevent staple fibre 3 be detained near the wall or attached to wall on.And, utilize the injection stream of roller unit 10 sides to suppress ascending air in the wind-tunnel 30, so staple fibre 3 can not disperse to the machine outside.
In addition, with staple fibre agitating plate 32 tilted configuration, and make end 33a with roller unit 10 opposite sides at lower, so can adjust the air quantity of main channel side and subaisle side, can adjust the intensity of injection stream and the intensity of eddy current etc. simply thus by changing this inclined degree.
And, about faller gill roller 12, if the periphery of faller gill 14 opposed roller main bodys 13 vertical (along diametric(al)) or tilt to the direction of rotation rear, the cutting action of the fibrous material 2 in the faller gill 14 relative housings 11 strengthens easily, the staple fibre 3 that is formed by fibrous material 2 shortens, might make staple fibre 3 easy entanglement not to each other, but in the present embodiment, make the diameter inclination of faller gill 14 opposed roller main bodys 13 and make its front end be positioned at direction of rotation the place ahead of faller gill roller 12, prolong the thorn angle of incidence of faller gill 14 relative fibrous materials 2 thus, eliminated the trend that staple fibre 3 shortens.Therefore, can form the staple fibre 3 of longer dimension, when a plurality of staple fibres 3 of gathering are made artificial cottons, produce the effect that staple fibre 3 fully tangles to each other, can make the good artificial cotton of intensity.
