The specific embodiment
Fig. 1 shows the Weft insertion nozzle 1 of spraying type weaving machine of the present invention, the profile of Fig. 2 for cutting open along the A-A line among Fig. 1, the profile of Fig. 3 for cutting open along the B-B line among Fig. 1.In these figure, Weft insertion nozzle 1 comprises: knitting needle 3 and the nozzle body 5 that is provided with water supply hole 4 with thread guide eyelet 2.Nozzle body 5 is a tubular, and have the nozzle bore 13 that is communicated with water supply hole 4 and lead to nozzle bore 13 but internal diameter than its little exit wound of bullet 10.Water supply hole 4 is communicated with not shown pump as the press water supply source, and towards nozzle bore 13 openings.
Knitting needle 3 is inserted in the nozzle bore 13, between the side face of the outer peripheral face of knitting needle 3 and nozzle bore 13, that is and the inner peripheral surface of nozzle body 5 between formed the ring-type stream 6 that is communicated with water supply hole 4.In illustrated scope, ring-type stream 6 is by the rectification stream 8 that is provided with a plurality of commutators 7 (first commutator 14 and second commutator 15) along the picking direction be located at rectification stream 8 downstreams and more little, its section of the one effluent road area of section constitutes by continuous in a circumferential direction round-formed acceleration stream 9 and by the big footpath stream 21 that exit wound of bullet 10 forms the closer to the downstream.
Never illustrated pump, by water supply hole 4 for the press water that comes, flow into ring-type stream 6 and in rectification stream 8 by rectification after, be brought to together quickening stream 9 to be accelerated the back again, in the stream 21 of big footpath, expand, eject towards the picking direction as the exit wound of bullet 10 of jet water course from front end.
More particularly, knitting needle 3, its rear end seamlessly is inserted in the nozzle bore 13, and is fixed on the nozzle body 5 by nut 11 is installed, and the O type of having packed between nozzle bore 13 and knitting needle 3 circle 12, press water just can not drain to wire guide 2 one sides.The leading section 17 of knitting needle 3, its front end is thin, and is more outstanding in the cylinder part 16 of part foremost from be inserted in nozzle bore 13, towards exit wound of bullet 10.
And knitting needle 3 comprises first commutator 14 as the commutator 7 of upstream one side, and is formed with the first rectification stream 8a.The inner peripheral surface of first commutator 14 from the outer peripheral face of knitting needle 3 towards nozzle body 5 be outstanding radially, and form in a circumferential direction a plurality of first rectification wall 14a that arranging, extending along radial direction with a plurality of intervals thus.In this embodiment, first commutator 14 forms a plurality of rectifier tanks 18 by machining knitting needle 3, by constituting one with knitting needle 3 same parts, can obtain the high-axiality with knitting needle 3 with this.The end of a plurality of first rectification wall 14a in first commutator 14, or contact or leave certain clearance with the inner peripheral surface of nozzle body 5, on the axis direction of knitting needle 3, extend.The bottom of rectifier tank 18, for the closer to spraying just dark more inclined plane shape of a side channel, downstream one side end of bottom is connected on sleekly by circular-arc outer peripheral face 20 on the leading section 17 of knitting needle 3.
In (1) of Fig. 2, the outer edge of first commutator 14 seamlessly contacts with the inner peripheral surface of nozzle body 5.Like this, even or the distortion that causes because of press water or become inner peripheral surface that a part or the whole first rectification wall 14a leave nozzle body 5 because of machining accuracy, installation accuracy, be discord inner circumferential surface state of contact, but the gap that produces owing to this separation is also very little.Therefore, all press water all passes through rectifier tank 18 and by rectification.In this embodiment, the section of rectifier tank 18 forms and is rectangle by being parallel to diametric.
And (2) of Fig. 2 and (3) show other examples of first commutator 14.At first, the external diameter of first commutator 14 in Fig. 2 (2) is littler than the aperture of nozzle bore 13.Compare with the sort of situation shown in (1) of Fig. 2, because the inner peripheral surface contact of first rectification wall 14a discord nozzle body 5 at this moment, so even the external diameter of the first rectification wall 14a has deviation, also first commutator 14 can be inserted in the nozzle bore 13 reliably, so be easy to Weft insertion nozzle 1 is assembled.In this case, can around the central shaft of thread guide eyelet 2, not separate along the current of the press water of the inner peripheral surface of nozzle body 5, also just can not be by rectification, but can be by the in addition rectification of second commutator 15 in downstream.In addition, first commutator 14 in Fig. 2 (3), the section of its first rectification wall 14a forms and for rectangle, rectifier tank 18 forms triangle by being parallel to diametric.It is become after such section shape, and the width of the base portion of rectification wall 14a (center one side) and leading section (nozzle body 5 interior Monday side) has just equated.Its benefit is, can improve the strength of parts of first commutator 14, obtains bigger stream section, compares with (1) of Fig. 2, the situation shown in (2), can not weaken flowing of press water.
Any situation among Fig. 2 all is to form the first rectification wall 14a by being parallel to diametric, so the situation that flow path cross sectional area diminish, flow path resistance increase such of the first rectification wall 14a at the expansion of rectifier tank one side, rectifier tank 18 can not occur.Like this, just can be under the situation of the force and velocity of a current that does not weaken press water, the current of press water are carried out rectification.In addition, as shown in Figure 1, the part with the axis normal of knitting needle 3 is all contained in the end of upstream one side of the first rectification wall 14a and the end of downstream one side.Therefore, can be under the state of the length of the axis direction of keeping first commutator 14, form and the first big rectification wall 14a of contact area of press water, and effectively with the press water rectification.
On the other hand, as second commutator 15 of the commutator of downstream one side, constituting for nozzle body 5 is the part of the cylinder part 16 of other parts.Cylinder part 16 with the same line of central shaft of first commutator 14 (knitting needle 3) on have bellmouth 16a, its external peripheral zone is entrenched in the nozzle bore 13.One side attenuates bellmouth 16a towards the downstream, and more toward front end between the outer peripheral face of the leading section 17 of thin more knitting needle 3, form the second rectification stream 8b and quicken stream 9.The ring-type stream section of the second rectification stream 8b and acceleration stream 9 all forms the form that reduces gradually towards the downstream.And, consider that commutator 7 (first commutator 14 and second commutator 15) can wear and tear because of press water, wait by pottery, carbide alloy or stainless steel and make commutator 7 (first commutator 14 and second commutator 15).
In the second rectification stream 8b, second commutator 15 is outstanding towards the outer peripheral face of the leading section 17 of knitting needle 3 from inner peripheral surface one side of nozzle body 5, forms a plurality of triangle rectification wall 15a that a plurality of compartment of terrains are arranged, extended along radial direction in a circumferential direction thus.Though cylinder part 16 is different parts with nozzle body 5, but because of the same with knitting needle 3, cylinder part 16 seamlessly is entrenched in the nozzle bore 13, so both kept the high-axiality of relative knitting needle 3, and can between the leading section 17 of it and knitting needle cylindraceous 3, form the second rectification stream 8b again and quicken stream 9.And, if can process, then can with cylinder part 16 (the second rectification stream 8b and quicken stream 9) as and nozzle body 5 same parts and forming as one.
A plurality of second rectification wall 15a process a plurality of rectifier tanks 19 by the peristome in the upstream of cylinder part 16 side and form.The peristome that the degree of depth of rectifier tank 19 is processed to one side from the upstream towards downstream a side shoal gradually, can't see at the middle part of cylinder part 16 seam ground sleekly with quicken stream 9 and couple together.In addition, the inner peripheral surface of the second rectification wall 15a of second commutator 15 is consistent in the gradient of axis direction with the inner peripheral surface that quickens stream 9.Therefore, by the press water of rectification with along the press water of the inner peripheral surface of the second rectification wall 15a, can in quickening stream 9, flow on non-resistance ground, can not weaken its force and velocity of a current at the second rectification stream 8b.
Then, illustrate that the desirable position between first commutator 14 and second commutator 15 concerns.In order to carry out rectification not hindering under the situation about flowing of press water, allow the rectifier tank 18 of first commutator 14 and rectifier tank 19 quantity of second commutator 15 equate, and for pairing each rectifier tank 18,19 is point-blank being alignd the circumferencial direction of knitting needle 3 and the circumferencial direction of cylinder part 16 on angle on the axis direction.And, because if between first commutator 14 and second commutator 15 slit is arranged, the movement disorder of (interval between the first rectification stream 8a and the second rectification stream 8b) press water in this interval then is so allow them approaching as best one can when preferably arranging first commutator 14 and second commutator 15.
But, if assemble first commutator 14 and second commutator 15 in a circumferential direction with departing from, then first commutator 14 and second commutator 15 near can causing turbulence state on the contrary, consider assembly error and with the two form of being arranged to suitably leave so be actually.Therefore, preferably arrange first commutator 14 and second commutator 15, the interval of first commutator 14 and second commutator 15 is all lacked than the length of any one in first commutator 14 and second commutator 15, in the example of Fig. 1, arrange knitting needle 3 and cylinder part 16, make the part of downstream one side end of first commutator 14 and circular-arc peripheral part 20 partly overlapping.Setting the length of the axis direction of circular-arc peripheral part 20 all lacks than the length of any one in first commutator 14 and second commutator 15.Press water by first commutator 14 just flows in second commutator 15 under the situation that does not become turbulence state thus.
As mentioned above, flow through the press water of ring-type stream 6, earlier carry out rectification by the first rectification stream 8a that is from the current that 14 pairs outstanding radially in first commutator of knitting needle 3 is mainly lateral element in the radial direction, then, carry out rectification by rectification stream 8b that is from the inner peripheral surface of nozzle body 5 current that 15 pairs outstanding in second commutator is mainly lateral element radial direction outside towards the axle center again, in acceleration stream 9, gather and speedup again.Afterwards, this press water arrives big footpath stream 21 and expands sharp, becomes injection stream and sprays at high speed from ejiction opening 10.
Because the leading section 17 of knitting needle 3 is outstanding very little from cylinder part 16, so the jet water course of emitting from acceleration stream 9 advances along the described ledge outside of knitting needle 3, thus, the advancing property to preshoot of jet water course can improve.And, because of jet water course is guided by big footpath stream 21 and knitting needle guided rings 22, so but advancing property is kept on the limit, and eject from ejiction opening 10 on the limit.The ring-type jet water course that is sprayed is drawn weft yarn from thread guide eyelet 2, and the surrounding edge guiding weft yarn that the limit surrounds weft yarn carries out picking.
Secondly, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8 show other embodiments of the invention.At first, in Fig. 4 and Fig. 5, nozzle body 5 has body abutment seat 23 supporting of head race 24 by inside, and for the press water that comes, the endless groove 25 and the water supply hole 4 of the outside by being formed on nozzle body 5 are supplied in the ring-type stream 6 from head race 24.In addition, for ease of processing, omitted the inclined-plane in the bottom of the rectifier tank 18 of first commutator 14.Equally, also make second commutator, 15 parts of cylinder part 16 also omit the inclined-plane, make second commutator 15 for slot-shaped, its rectification wall is kept by acceleration stream 9 parts of cylinder part 16.
In Fig. 6 and Fig. 7,, make first commutator 14 be different parts with knitting needle 3 for ease of making.First commutator 14 is made of with the jut 26 that is entrenched in the outer peripheral face of knitting needle 3 the first rectification wall 14a, and they constitute one.In this case, can be by the outer peripheral face that method is fixed to jut 26 on knitting needle 3 such as being pressed into or bonding.But,, preferably make the external diameter of jut 26 littler than the external diameter of the outer peripheral face of the adjacent knitting needle 3 of upstream one side for controlled pressure water strikes the jut 26 of first commutator 14.And, in this embodiment, for easy processing component, constitute the second rectification stream 8b and quicken stream 9 by two cylinder parts 27,28, but at this moment in order not hinder flowing of press water, the outer peripheral face of preferably arranging the inner peripheral surface of rectification wall of cylinder part 27 and cylinder part 28 does not have step and the gradient on axis direction consistent.And, if pay attention to rectification effect, also can allow the outer peripheral face of leading section 17 of the inner peripheral surface of rectification wall of second commutator 15 of cylinder part 27 and knitting needle 3 contact.Like this, just can carry out rectification by the current of the radial direction inboard of 15 pairs of press waters of second commutator.
And then in Fig. 8, shown for the leading section 17 of knitting needle 3 not from quickening the type that stream is 9 outstanding, omitted big footpath stream 21.
As mentioned above, in embodiment shown in Figure 8, be provided with first commutator 14 and second commutator, 15 these two commutators as commutator 7 at Fig. 1, but also can multistage on the axis a plurality of commutators 7 more than 3 are set.
