In order to further understand the contents, features and functions of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
To the problem that prior art exists, the utility model provides an exchange formula super wide width electromagnetic drive wefting insertion device, it is right to combine below the attached drawing 1 to fig. 8 the utility model discloses do detailed description.
An alternating current type ultra-wide electromagnetic drive weft insertion device comprises an electromagnetic weft insertion guide rail. The electromagnetic weft insertion track comprises an electromagnetic coil 7, an iron core 5 and a weft insertion device 6. The current passed by the electromagnetic coil 7 is alternating current, the electromagnetic coil 7 is wound on the iron core 5, and when the electromagnetic coil 7 is electrified, the electromagnetic coil 7 interacts with the permanent magnet 16 on the weft insertion device 6 to push the weft insertion device 6 to move forwards continuously. The iron core 5 is made of aluminum. The weft insertion device 6 is provided with two permanent magnets 16. When the fabric 1 is going to perform weft insertion movement, the controller turns on the power supply to energize the coils on the iron core 5, and the weft insertion device 6 moves towards the opposite side through the shed formed by the warp threads at a stable and controllable speed under the action of electromagnetic force.
As shown in fig. 2, the weft insertion device 6 is located in a guide groove formed by the side-by-side cores 5.

The permanent magnet 16, which constantly changes the direction of the magnetic field, interacts with two permanent magnets 16 on the weft insertion device 6, so that the weft insertion device 6 can be moved. The weft insertion device 6 advances because the permanent magnet S pole at the head of the weft insertion device 6 is attracted by the electromagnet N pole at the back and is repelled by the electromagnet (S pole) at the front at the same time. When the weft insertion device 6 reaches the next position, the current flow in the weft insertion coil 2 is reversed. The result is that the original N-pole coil now becomes the S-pole coil.
