The rollback point of motion, then the space of top shed 49 reach maximum.Under the change of shed open, weft yarn is incorporated into by upper strata shuttle 27
In the top shed 49 of woven new opening and on fabric, next group of weft yarn by it is next upper strata shuttle 27 carry introduce it is next
Individual top shed 49 (being opened in succession with first shed open).
Under lower floor's shed open open mode, lower shed 50 is formed by middle level warp thread group 47-2, lower layer warp yarns group 47-3
One shed open space, now lower floor's shuttle 24 carries weft yarn and rotated in lower-layer gate door track 35, while weft yarn is incorporated into
In lower shed 50, and it is urgent on fell ring gauge 26.If outer layer heald frame heald eyelet 15-1 and internal layer heald frame heald eyelet 13-
If 1 is located at the same horizontal position, then lower shed 50 is closed, and middle level warp thread group 47-2, lower layer warp yarns group 47-3 also are located at same
Plane.The size in the space of lower shed 50 is determined by two groups of warp thread, and middle level warp thread group 47-2, lower layer warp yarns group 47-3 positions are not
Disconnected change forms shed open.Since being started shed closed, if middle level warp thread group 47-2, lower layer warp yarns group 47-3 are located at their phases
To the rollback point of itself alternating movement, then the space of lower shed 50 reaches maximum.Under the change of shed open, weft yarn is by lower floor's shuttle
Son 24 is incorporated into the lower shed 50 of woven new opening and on fabric, and next group of weft yarn carries lower floor's shuttle 24 by next
And introduce next lower shed 50 (being opened in succession with first shed open).
In the present invention, cause upper strata shuttle to being passed through alternating current in upper strata magnet exciting coil 32 and lower floor's magnet exciting coil 37 respectively
Son 27 and lower floor's shuttle 24) around form respective magnetic field respectively, magnetic field produces with the change in size of current and direction
The magnetic field that the waveform magnetic field of sinusoidal variations rule, upper strata permanent magnet 33 and lower floor's permanent magnet 36 are formed is fixed, so encouraging
The magnetic field that magnetic coil is formed and the magnetic field interaction of permanent magnet itself, thrust is produced to upper strata shuttle 27 and lower floor's shuttle 24 and made
With the speed that upper strata shuttle 27 and lower floor's shuttle 24 move is determined by the pace of change in waveform magnetic field.Using linear electric motors come real
Existing electromagnetism wefting insertion, electromagnetism weft insertion system reduce the complexity of mechanical driving device to a certain extent, while also improve existing
There are some defects of shuttle sliding device wefting insertion, compensate for restriction of the existing wefting insertion shuttle to loom characteristic, add the reliability of system,
Also solves the problems, such as the weaving of wide format simultaneously.
In addition, lease rod 25 can preferentially be arranged in warp inlet side, electromagnetism picking motion is arranged in shedding mechanism, weaving
Between ring gauge 26, and upper strata shuttle 27 and lower floor's shuttle 24 be in round reed it is equidistant circumferentially, and circulate successively
Rotate.Motor A2 is connected by shaft coupling with decelerator 3, transmits power to rotating shaft F44, rotating shaft F44 after the deceleration of decelerator 3
Power is transmitted to conical gear C45 and conical gear D46, conical gear D46 drives rotating shaft B28 rotations, and rotating shaft B28 is by power
Transmitting to conical gear A30 and conical gear B31, conical gear B31 drives rotating shaft C 29 to rotate, and rotating shaft C 29 drives scroll cylinder 17
Rotation.The tubular fabric 48 of production is to concentrate arrangement woven from the weaving ring gauge 26 arranged to inner side, then by coiler drum
17 batch upwards, and the fabric of formation is as shown in figure 13.
From the weaving principle of 3-dimensional multi-layered tubular fabric, the loom in the present invention mainly realizes three mechanical movements,
It is that the opening of three layers of heald frame in shedding mechanism moves back and forth the circulation motion of weft-insertion with electromagnetism shuttle in electromagnetism weft insertion system respectively,
And the fabric take-off motion of spooler.
