In the present embodiment, as shown in fig. 6, 7 and 8, due to the principle of electromagnetic induction, the E-type coil 53 has different magnetic poles, when the E-type coil 53 is located at one side of the driving track 23 where N, S, N, S … … are arranged, due to the interaction between the permanent magnet magnetic field and the electromagnetic magnetic field, the permanent magnet on the driving track 23 generates two forces of F (N-N) and F (N-S) to the E-type coil 53, under the driving of the two forces, the E-type coil 53 moves along the driving track 23, when the E-type coil 53 completes one movement, the N pole of the E-type coil 53 moves to the N pole on the driving track 23, the magnetic pole change of the permanent magnet of the driving track 23 is detected by the magnetic pole sensor 51 in front, the current direction in the E-type coil 53 is changed by the control board, so that the magnetic pole of the E-type coil 53 changes from N to S, the magnetic poles of the iron cores on both sides of the E-type coil 53 are changed from S to N, so that the driving track 23 generates two new forces F (S-S) and F (S-N) to the E-type coil 53, and the E-type coil 53 continues to move forward along the driving track 23 under the driving of the two new forces. The control board continuously changes the direction of the current of the E-coil 53 to cause the E-coil 53 to continuously move along the drive track 23. When the brake is required to be stopped, a reverse current is introduced to enable the E-shaped coil 53 to generate a force opposite to the movement direction, so that the electromagnetic force acts reversely to perform deceleration braking on the E-shaped coil 53. Because the four E-shaped coils 53 are arranged between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, and the four E-shaped coils 53 are grouped in pairs, when one group of E-shaped coils 53 just exits from the driving magnetic track 23, the other group of E-shaped coils 53 enters the driving magnetic track 23, and a pair of E-shaped coils 53 always drive the weft insertion device 3, the weft insertion device component 3 continuously and circularly moves on the track, and the weft insertion process is completed.

In this embodiment, the above-mentioned one-time movement of the E-type coil 53 means that the weft insertion device 3 advances one magnetic pole on the driving magnetic track 23 along the driving magnetic track 23, and each time one magnetic pole advances, the control board controls the electromagnetic field of the E-type coil 53 to change, and further the magnetism of the three electromagnetic poles of the coil fixing seat 52 also changes synchronously, that is, the coil fixing seat 52 changes alternately between N, S, N and S, N, S, so as to match the magnetic field change of each magnetic pole advancing on the driving magnetic track 23, and further provide a continuous driving force for the movement of the weft insertion device 3 in the weft insertion slot rail 2.
