Abstract
The invention discloses an auxiliary nozzle mechanism, which comprises an auxiliary nozzle, a nozzle seat, a nozzle support and a servo motor. The tail of the auxiliary nozzle is inserted into a center hole of the nozzle seat, a rack is arranged on one side of the nozzle seat, the servo motor is mounted on the nozzle support, and a gear is mounted on an extending shaft of the servo motor and meshes with the rack. When auxiliary airflow is needed, the auxiliary nozzle extends into the middle of warps, and can return to a standby position after jetting is finished. Contacting time of the auxiliary nozzle with warp flows can be shortened and resistance force to the warps from the auxiliary nozzle is reduced, so that the warp flow can be leveled and ultrathin warps can be woven favorably.
Description
Technical field
The invention belongs to the loom field, relate to air-jet loom, relate to a kind of telescopic pilot jet mechanism specifically.
Background technology
Leap in the shed open process at weft yarn, pilot jet provides secondary air, and pilot jet must be inserted into when jet-stream wind in the shed open, and pilot jet is evenly distributed the resistance shelves that the pilot jet in the insertion warp thread has become warp thread to flow along reed width.
For fear of damage yarn, the pilot jet profile is made round flat shape, and head is made smooth streamlined.The injection direction of assistant nozzle air current makes progress more slightly, and plane inclined slightly is processed in the side of nozzle head, on the direction perpendicular to this plane, processes spray-hole.
Under the filling insertion way of special-shaped reed, the installation site of pilot jet receives the very big restriction of weaving process.When weaving the fabric of special thin warp thread, the thickness of pilot jet has become a kind of obstacle, and pilot jet is evenly distributed between the warp thread, and thicker pilot jet forms the sudden change of warp thread stream, has influenced the ability that air-jet loom is knitted special thin warp thread.
The continuity of weft tracting flow mainly relies on auxilliary gaseous blast, and therefore, the profile of auxilliary nozzle is the key technology of wefting insertion quality with direction, speed, the flow of the auxilliary gaseous blast of control.Under special-shaped reed filling insertion way, through gas channel, the thickness of nozzle produces bending greater than the splits between the reed wire during warp thread stream process nozzle to warp thread, causes warp thread stream not smooth from vertical direction.
Summary of the invention
For overcoming deficiency of the prior art, the present invention aims to provide a kind of telescopic pilot jet mechanism, to reduce the contact time of pilot jet and warp thread stream, reduces the resistance shelves of pilot jet to warp thread stream, and warp thread stream is tended to be steady.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of pilot jet mechanism; It comprises a pilot jet, a nozzle carrier, a nozzle holder and a servomotor; The afterbody of said pilot jet is inserted in the centre bore of said nozzle carrier, is provided with a tooth bar in a side of said nozzle carrier, and said servomotor is installed on the said nozzle holder; And a gear is installed on the projecting shaft of said servomotor, said wheel and rack meshes.
Further, said nozzle holder is installed in the T type groove of slay.
Further, offer a guide groove on the said nozzle holder, said nozzle carrier is along the removable 5-5.5mm of said guide groove.
Further, said servomotor is electrically connected a microcomputer, the stretching motion of the said pilot jet of the said driven by servomotor of said control of microcomputer.
Compared with prior art, the present invention has following beneficial effect:
Pilot jet of the present invention mechanism, when the needs secondary air, pilot jet puts in the middle of the warp thread, waits AEI After End of Injection, and pilot jet is got back to holding fix.Reduce pilot jet to the contact time that warp thread flows, reduce the resistance shelves power of pilot jet, warp thread stream is tended to be steady, help knitting special thin warp thread warp thread.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. detailed description.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.

Label declaration among the figure: 1, pilot jet, 2, nozzle carrier, 3, nozzle holder, 4, servomotor, 5, gear, 6, tooth bar, 7, slay, 8, T type groove.
The specific embodiment
Below with reference to accompanying drawing and combine embodiment, specify the present invention.
Referring to illustrated in figures 1 and 2; A kind of pilot jet mechanism, it comprises a pilot jet 1, a nozzle carrier 2, a nozzle holder 3 and a servomotor 4, the afterbody of said pilot jet 1 is inserted in the centre bore of said nozzle carrier 2; Side at said nozzle carrier 2 is provided with a tooth bar 6; Said servomotor 4 is installed on the said nozzle holder 3, and a gear 5 is installed on the projecting shaft of said servomotor 4, said gear 5 and said tooth bar 6 engagements.
Further, referring to shown in Figure 3, said nozzle holder 3 is installed in the T type groove 8 of slay 7.
Further, offer a guide groove on the said nozzle holder 3, said nozzle carrier 2 is along the removable 5-5.5mm of said guide groove.
Further, said servomotor 4 is electrically connected a microcomputer, and the said servomotor 4 of said control of microcomputer drives the stretching motion of said pilot jet 1.
Operation principle of the present invention referring to shown in Figure 4, is represented the operating angle that every group of pilot jet is flexible; Bent axle one changes 360o; The crank angle is the angle position of bent axle, and oblique line is represented the flight angle of weft yarn, and Fig. 4 shows that the flexible angle of pilot jet must match with the arrival angle of weft yarn.The expanding-contracting action of pilot jet is by driven by servomotor, and the action of each pilot jet receives system controlled by computer, presses the position at the relative reed width of pilot jet place, and in the reed width scope, pilot jet is divided into 4-8 group, and the actuation time of every group of pilot jet is just the same.Every group of pilot jet of system controlled by computer stretches out at certain degree in crank angle, in certain degree in crank angle withdrawal.
The above is merely preferred case study on implementation of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
