The magnetic support device 101 is used to support the magnetic conveying belt 300, and the magnetic tension device 102 is used to provide upward tension to the magnetic conveying belt 300. The magnetic support device 101 and the magnetic tension device 102 are arranged to jointly act on the magnetic conveying belt 300 and the material 2000 thereon to make the magnetic conveying belt 300 and the material 2000 thereon run in the air. In the return section 1002, the magnetic suspension support 100 comprises a magnetic attraction device 103 cooperating with the magnetic conveying belt 300 and located above the magnetic conveying belt 300 and a return supporting roller 104 located below the magnetic conveying belt 300. The magnetic attraction device 103 is used to provide an attractive force to the magnetic conveying belt 300 to make it float in the air. The return supporting roller 104 is used to support the magnetic conveying belt 300 in the shutdown state. The magnetic support device 101, the magnetic tension device 102 and the magnetic attraction device 103 can be electromagnets or permanent magnets, preferably electromagnets, so that the air gap and the running posture of the magnetic conveying belt 300 can be adjusted in real time by controlling the magnetic field of the electromagnets.

[0023] Referring to Figure 2 And Figure 4The magnetic conveying belt 300 comprises a main body 1, a plurality of energized coils 2 embedded in the interior of the main body 1 for forming a magnetic field, a pantograph connector 3 arranged at the bottom of the main body 1, a pantograph 4 mounted on the pantograph connector 3, and a magnetic conductor suspension device 5 arranged at the two side edges of the main body 1 respectively. In this embodiment, from top to bottom, the main body 1 comprises an upper cover rubber 11, a first reinforcing layer 12, a coil limiting rubber layer 13, a second reinforcing layer 14, and a lower cover rubber 15. The upper cover rubber 11 can be made of rubber, thermoplastic polyolefin or the like, and is used for contacting and carrying the material 2000. The lower cover rubber 15 can be made of rubber, thermoplastic polyolefin or the like, and is used for contacting the bottom support in the non-working state. The coil limiting rubber layer 13 is used for covering the plurality of energized coils 2, and can be made of rubber, thermoplastic polyolefin or the like, and is used for limiting and protecting the plurality of energized coils 2, and can limit the plurality of energized coils 2 in a specific position area and space, effectively play the function of generating a magnetic field, and effectively protect the plurality of energized coils 2.

[0024] Continuing with the description of the magnetic conveying belt 300, Figure 2 and Figure 4 The middle region of the main body 1 is a magnetic region M, which is preferably an electromagnetic region. The adjacent surface of the magnetic region M and the magnetic support device 101 has the same magnetic pole; the adjacent surface of the magnetic region M and the magnetic attraction device 103 has the opposite magnetic pole. The magnetic support device 101 and the magnetic conveying belt 300 are in a non-contact magnetic levitation state by using the principle that the same magnetic poles repel each other; the magnetic attraction device 103 can attract the magnetic conveying belt 300 to levitate in the air by using the principle that the opposite magnetic poles attract each other. Arranging the middle region of the main body 1 as a magnetic region M can make the magnetic repulsion of the magnetic support device 101 to the magnetic conveying belt 300 act on the part that needs the most force in the middle.

[0025] Referring to the magnetic conveying belt 300, Figures 2 to 4The magnetic suspension conveyor 1000 includes the conductive wire 6 matched with the pantograph 4, and the magnetic conveyor belt 300 is continuously powered through the conductive wire 6 to achieve the purpose of continuously generating the required electromagnetic magnetic field. In this embodiment, the conductive wire 6 includes a first conductive wire 61 arranged on the material carrying section 1001 and a second conductive wire 62 arranged on the return section 1002. In combination with Figure 1 In the transverse direction perpendicular to the moving direction F of the magnetic conveyor belt 300, the magnetic support device 101 includes oppositely arranged first and second magnetic support devices 1011 and 1012, and the first and second magnetic support devices 1011 and 1012 are spaced apart to form a first active space 1013 matched with the pantograph 4 therebetween. In the transverse direction perpendicular to the moving direction F of the magnetic conveyor belt 300, the magnetic attraction device 103 includes oppositely arranged first and second magnetic attraction devices 1031 and 1032, and the first and second magnetic attraction devices 1031 and 1032 are spaced apart to form a second active space 1033 matched with the pantograph 4 therebetween. In this way, on the one hand, it is more conducive to the arrangement of the relevant components of the magnetic suspension conveyor 1000; on the other hand, when the magnetic suspension conveyor 1000 is in a stopped state, the gravity of the magnetic conveyor belt 300 and the material 2000 thereon can be reduced or even avoided to exert excessive pressure on the pantograph 4 and damage the pantograph 4 and the main body 1. The matching relationship between the pantograph 4 and the first active space 1013 can be determined according to specific conditions, for example, in the running state and the stopped state, the pantograph 4 extends into the first active space 1013, and in this embodiment, the first conductive wire 61 passes through the first active space 1013 in both states; for another example, in the running state and the stopped state, the pantograph 4 penetrates through the first active space 1013, and in this embodiment, the first conductive wire 61 is located below the first active space 1013 in both states; for another example, in the running state, the pantograph 4 extends into the first active space 1013, and in the stopped state, the pantograph 4 penetrates through the first active space 1013, and in this embodiment, in the running state, the first conductive wire 61 passes through the first active space 1013, and in the stopped state, the first conductive wire 61 is located below the first active space 1013. The height of the first conductive wire 61 is preferably adjustable. The matching relationship between the pantograph 4 and the second active space 1033 is the same as or similar to that between the pantograph 4 and the first active space 1013, and will not be described here. Of course, in other embodiments, the power supply of the pantograph 4 on the material carrying section 1001 and the return section 1002 can also be provided by the same conductive wire.

With such an arrangement, on the one hand, the magnetic support device 101 and the magnetic pulling device 102 work together with the magnetic conveyor belt 300 and the material 2000 thereon, so that the magnetic conveyor belt 300 and the material 2000 thereon are suspended in the air; on the other hand, the magnetic conveyor belt 300 can be made into a trough-shaped structure in the material-carrying section 1001, which is more convenient for conveying the material 2000. The first horizontal limiting device 1022 and the second horizontal limiting device 1024 are used to balance the lateral force of the magnetic conveyor belt 300, prevent the magnetic conveyor belt 300 from deviating, and prevent the magnetic conveyor belt 300 from shrinking toward the center under the weight of the material 2000.
