[0032] In this embodiment, the present invention provides a first suspension magnetic track 23 and a second suspension magnetic track between the weft insertion device 3 and the weft insertion groove track 2, so that the weft insertion device 3 can be suspended above the weft insertion groove track 2; and by providing a driving magnetic track 22 on the two side walls of the weft insertion groove track 2, a magnetic pole sensor 32 is provided in the weft insertion device 3, and the magnetic pole sensor 32 generates different magnetic poles according to the stimulation change of the driving magnetic track 22, and then drives the weft insertion device 3 to move along the driving magnetic track 22 through the magnetic pole change, and the yarn carrier 4 on the weft insertion device 3 pulls the yarn to follow the movement of the weft insertion device 3; by adopting magnetic suspension and magnetic force to drive the weft insertion device 3 to move, the weft insertion device 3 moves in the weft insertion groove track 2, with fast speed, less mechanical friction, no mechanical impact, high weft insertion efficiency, low noise, and can realize full-automatic weft insertion, greatly reducing the difficulty of operation, and improving the production efficiency of the three-dimensional multi-layer cylindrical loom. Therefore, the present invention is not only simple in structure, labor-saving, but also high in work efficiency.

[0033] In this embodiment, if Figure 5 As shown, specifically, the magnetic pole sensor 32 is an E-type coil group, which includes a coil fixing seat 52, an E-type coil 53 and two magnetic pole sensors 51. The two magnetic pole sensors 51 are symmetrically arranged on both sides of the coil fixing seat 52, and the E-type coil 53 is arranged on the coil fixing seat 52; the coil fixing seat 52 is provided with three iron cores at equal intervals in sequence, and the E-type coil 53 is installed on the middle iron core. When the E-type coil 53 is energized, the adjacent iron cores on the same coil fixing seat 52 have different magnetic properties.

[0034] In this embodiment, the magnetic pole sensor 32 energizes the E-type coil 53, so that the E-type coil 53 generates an electromagnetic field, thereby causing the coil fixing seat 52 to generate three electromagnetic poles, and because the middle electrode is located inside the E-type coil 53, the magnetic properties of the middle electromagnetic pole are different from those of the electromagnetic poles on both sides; specifically, the power source for generating the electromagnetic field is a battery arranged inside the weft inserter 3.

[0035] In this embodiment, if Figure 3 As shown, specifically, the weft insertion groove rail 2 is a circular groove rail, and the weft insertion device 3 includes an arc-shaped upper weft insertion shuttle plate 33 and a lower weft insertion shuttle plate 34, and a plurality of magnetic pole sensors 32 are evenly arranged between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, and the second suspended magnetic rail is arranged at the bottom of the lower weft insertion shuttle plate 34.

[0036] In this embodiment, if Figure 3 As shown, specifically, four magnetic pole sensors 32 are evenly arranged between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, and the magnetic poles of two adjacent magnetic pole sensors 32 face the driving magnetic rails 22 on different sides.

[0037] In this embodiment, as an option, a control board is further provided between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, and the control board is used for changing the magnetic poles of the plurality of magnetic pole sensors 32; and the end surfaces of the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34 are both provided with a plurality of guide wheels 31.

[0038] In this embodiment, specifically, the control board uses an STM32 single-chip microcomputer development board and a dual-path H-bridge circuit board, and is used to simultaneously control the direction and magnitude of the current in the four E-type coils, thereby controlling the magnetic changes of the three cores of the coil fixing seat 52.

[0039] In this embodiment, if Figure 3 As shown, specifically, the upper end surface of the upper weft insertion shuttle plate 33 and the lower end surface of the lower weft insertion shuttle plate 34 are each provided with four guide wheels 31, and the four guide wheels 31 are respectively distributed at the four vertex corners of the upper end surface of the upper weft insertion shuttle plate 33 or the lower end surface of the lower weft insertion shuttle plate 34.

[0040] In this embodiment, if Figure 2 As shown, the two driving magnetic rails 22 are arranged at the same height position on the two side walls of the weft insertion groove rail 2, and the driving magnetic rails 22 include a plurality of driving magnetic poles. The magnetic properties of two adjacent driving magnetic poles are different, and the driving magnetic poles are all permanent magnets.

[0041] In this embodiment, specifically, the weft insertion groove rail 2 includes two mounting side walls 21 and a bottom wall, the first suspension magnetic rail 23 is mounted on the bottom wall, the driving magnetic rail 22 is mounted at the same height of the two mounting side walls 21, and at the same time, the two mounting side walls 21 are provided with limiting portions to prevent the weft inserter 3 from detaching from the weft insertion groove rail 2.

[0042] In this embodiment, if Figure 8 As shown, the first suspension magnetic track 23 and the second suspension groove track have the same magnetic poles at corresponding positions.

[0043] In this embodiment, specifically, the magnetic pole sensors 51 are fixed on the front and rear sides of the movement direction of the E-type coil 53. The magnetic pole sensors 51 on the front and rear sides are used to detect the instantaneous magnetic pole change in front of the driving magnetic track 22 on the side of the E-type coil 53 in different movement directions. The E-type coil 53 is made of an E-type iron block, and copper wire is wound on the iron core in the middle of the iron block. A total of 4 E-type coils are fixed on the weft insertion shuttle plate to jointly drive the weft insertion shuttle plate. The E-type coil 53 is fixed between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, and the yarn carrier 4 is installed on the upper weft insertion shuttle plate 33. The second suspension magnetic track at the bottom of the lower weft insertion shuttle plate 34 and the first suspension magnetic track 23 at the bottom of the weft insertion groove track 2 are both permanent magnet magnetic tracks, and the magnetic poles at the corresponding positions of the second suspension magnetic track and the first suspension magnetic track 23 have the same magnetism, that is, both are N-pole magnetic tracks or both are S-pole magnetic tracks, thereby forming a mutually repulsive force, so that the weft insertion device 3 is suspended in the weft insertion groove track 2, and the E-type coil 53 after being energized moves in a circular direction under the traction force in the magnetic field to complete the circular weft insertion movement. When the weft line needs to be stopped after the weft line is inserted, a reverse current is introduced to make the magnetic field generate a reverse force on the E-type coil, so that the weft insertion device 3 completes the braking stop.

[0044] In this embodiment, specifically, two rows of first suspension magnetic rails 23 are laid at the bottom of the weft insertion groove 2, one row of the first suspension magnetic rails 23 is an N-grade magnet, and the other row of the first suspension magnetic rails 23 is an S-grade magnet 73; in addition, there are two corresponding arc-shaped magnets at the bottom of the lower weft insertion shuttle plate 34, and the entire weft insertion device 3 is suspended by the mutual repulsion of like magnetic poles. At the same time, driving magnetic rails 22 are laid on both sides of the groove, and the driving magnetic rails 22 are arranged in the order of N, S, N, S, N...S magnetic poles. Four magnetic pole sensors 32 are fixed between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, and the four magnetic pole sensors 32 are grouped in pairs, one group of magnetic pole sensors 32 faces the inner ring side driving magnetic rail 22 and is pulled by the inner ring side driving magnetic rail 22, and the other group of magnetic pole sensors 32 faces the outer ring side and is pulled by the outer ring side driving magnetic rail 22, thereby driving the weft insertion device components to move and complete the circular weft insertion action.

[0045] In this embodiment, if Figure 6 , Figure 7 and Figure 8As shown, due to the principle of electromagnetic induction, the E-type coil 53 will have different magnetic poles. When the E-type coil 53 is located on one side of the driving magnetic track 22 arranged in N, S, N, S..., due to the interaction between the permanent magnet magnetic field and the electromagnetic magnetic field, the permanent magnet on the driving magnetic track 22 will generate two forces F(NN) and F(NS) on the E-type coil 53. Driven by these two forces, the E-type coil 53 will move along the direction of the driving magnetic track 22. When the E-type coil 53 completes one movement, the N pole of the E-type coil 53 moves to the driving magnetic track 22. At the N pole on the moving magnetic track 22, the magnetic pole sensor 51 in front detects the change of the magnetic pole of the permanent magnet of the driving magnetic track 22, and changes the direction of the current in the E-type coil 53 through the control board, so that the magnetic pole of the E-type coil 53 changes from N to S, and the magnetic poles of the iron cores on both sides of the E-type coil 53 change from S to N. In this way, the driving magnetic track 22 will generate two new forces F (SS) and F (SN) on the E-type coil 53. Driven by these two new forces, the E-type coil 53 will continue to move forward along the driving magnetic track 22. The control board continuously changes the current direction of the E-type coil 53, prompting the E-type coil 53 to move continuously along the driving magnetic track 22. When it is necessary to stop, a reverse current is passed to make the E-type coil 53 generate a force opposite to the direction of movement, thereby performing reverse work through the electromagnetic force to decelerate the E-type coil 53. Since four E-type coils 53 are arranged between the upper weft insertion shuttle plate 33 and the lower weft insertion shuttle plate 34, the four E-type coils 53 are grouped in pairs. When one group of E-type coils 53 just leaves the driving magnetic track 22, the other group of E-type coils 53 enters the driving magnetic track 22. There is always a pair of E-type coils 53 driving the weft insertion device 3, thereby realizing the continuous circular motion of the weft insertion device components on the track to complete the weft insertion process.

[0046] In this embodiment, the above-mentioned E-type coil 53 completes one movement, which means that the weft inserter 3 advances one magnetic pole along the driving magnetic track 22. Every time it advances one magnetic pole, the control board will control the electromagnetic field of the E-type coil 53 to change, and then the magnetism of the three electromagnetic poles of the coil fixing seat 52 will also change 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 on the driving magnetic track 22, thereby providing a continuous driving force for the movement of the weft inserter 3 in the weft insertion groove track 2.
