Abstract
The utility model discloses an auxiliary nozzle mechanism which comprises an auxiliary nozzle, a nozzle base, a nozzle bracket and a servo motor, wherein the tail of the auxiliary nozzle is inserted into a central hole of the nozzle base; a rack is arranged on one side of the nozzle base; the servo motor is mounted on the nozzle bracket; a gear is mounted on an extending shaft of the servo motor; and the gear is engaged with the rack. The auxiliary nozzle mechanism provided by the utility model is characterized in that the auxiliary nozzle extends into warps when the auxiliary airflow is required and the auxiliary nozzle returns to a waiting position after the ejection is ended; the contact time between the auxiliary nozzle and the warp flow is reduced; the resisting force of the auxiliary nozzle to the warps is reduced; the warp flow is tended to be stable; and the auxiliary nozzle mechanism is beneficial to the weaving of ultrafine warps.
Description
Technical field
The utility model belongs to the loom field, relates to air-jet loom, relates 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.
The utility model content
For overcoming deficiency of the prior art, the utility model 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 utility model is realized 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 utlity model has following beneficial effect:
The pilot jet mechanism of the utility model, 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 the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment and the conjunction with figs. detailed description of the utility model.The specific embodiment of the utility model 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 utility model.
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.
The operation principle of the utility model 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 preferred case study on implementation that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
