[0029] like Figures 1 to 4 As shown, an embodiment of the present invention provides a conveying device, and the conveying device can be used to convey a workpiece 600 such as a plate such as a steel plate, or a coiled material strip after unwinding a coil, or a wheel hub or a fender, etc. Figure 3 In the embodiment, the workpiece 600 being conveyed is a plate. The conveying device includes: a conveying roller 100, a magnetic drive mechanism 200, and a support rod 300. A plurality of conveying rollers 100 are provided, and the conveying rollers 100 are rotatable, thereby facilitating the movement of the conveyed workpiece 600. All conveying rollers 100 are arranged at intervals along the conveying direction of the conveying device. Preferably, the axial direction of the conveying rollers 100 is arranged perpendicular to the conveying direction of the conveying device. Magnetic members 120 are provided at both ends of the axial direction of each conveying roller 100. The magnetic members 120 can be permanent magnets or electromagnets. The number of magnetic drive mechanisms 200 should be twice the number of conveying rollers 100. The magnetic drive mechanisms 200 are arranged in a one-to-one correspondence with the magnetic members 120. The magnetic drive mechanisms 200 are arranged opposite to the corresponding magnetic members 120. During the operation of the conveying device, the magnetic drive mechanisms 200 can generate a magnetic attraction force with the corresponding magnetic members 120. In this way, under the action of the magnetic members 120 at both ends of the conveying rollers 100 and the magnetic drive mechanisms 200, the conveying rollers 100 can be located in a suspended posture within the support frame. The support rods 300 extend along the conveying direction of the conveying device and are also connected to each conveying roller 100. The support rods 300 are mainly used to fill the gap between the two connected conveying rollers 100. To this end, the portion of the support rods 300 in contact with the conveyed workpiece 600 is lower than the portion of the conveying roller 100 in contact with the conveyed workpiece 600, or the portion of the support rods 300 in contact with the conveyed workpiece 600 is flush with the portion of the conveying roller 100 in contact with the conveyed workpiece 600.

[0030] In the conveying device provided in this embodiment, the conveying roller 100 is able to levitate under the action of the magnetic member 120 and the magnetic drive mechanism 200. When the workpiece 600 being conveyed contacts the conveying roller 100, the position of the conveying roller 100 can be adaptively adjusted according to the weight of the workpiece 600 being conveyed. Compared with the prior art, this can reduce the wear of the conveying roller 100 and increase the service life of the conveying roller 100. The support rod 300 can fill the gap between two adjacent conveying rollers 100, thereby preventing the head of the conveyed workpiece 600 from falling into the gap between the two adjacent conveying rollers 100.

[0031] Optionally, in the embodiment, the magnetic attraction force between the magnetic driving mechanism 200 and the magnetic member 120 should meet the load bearing requirement of the conveying roller 100, so as to avoid the falling of the conveying roller 100 due to the load bearing of the conveying roller 100.

[0032] In the optional implementation of the embodiment, the conveying roller 100 is provided with an annular groove 110 corresponding to the supporting rod 300, and the supporting rod 300 is located in the groove, so that the part of the supporting rod 300 in contact with the conveyed workpiece 600 is lower than the part of the conveying roller 100 in contact with the conveyed workpiece 600, or the part of the supporting rod 300 in contact with the conveyed workpiece 600 is flush with the part of the conveying roller 100 in contact with the conveyed workpiece 600.

[0033] In the embodiment, it is preferred that the part of the supporting rod 300 in contact with the conveyed workpiece 600 is lower than the part of the conveying roller 100 in contact with the conveyed workpiece 600, and the height difference between the part of the supporting rod 300 in contact with the conveyed workpiece 600 and the part of the conveying roller 100 in contact with the conveyed workpiece 600 is greater than or equal to 5 mm.

[0034] Further, the conveying device provided by the embodiment is provided with a supporting member 310 on the part of the supporting rod 300 away from the part in contact with the conveyed workpiece 600, the supporting member 310 can be integrally formed with the supporting rod 300 or can be installed on the supporting rod 300 by welding or riveting, the supporting member 310 is provided in one-to-one correspondence with the conveying roller 100, and the supporting member 310 can be connected into the annular groove 110 of the corresponding conveying roller 100. The supporting member 310 can be "L" shaped or arc-shaped, etc.

[0035] The conveying device provided by the embodiment not only can fill the gap between the adjacent two conveying rollers 100 to prevent the head of the conveyed workpiece 600 from falling into the gap between the adjacent two conveying rollers 100, but also can connect the front and rear two conveying rollers 100 to play a role of overall support and rigidity, so as to avoid the problems of large displacement, misplacement and bouncing of the conveying roller 100 due to uneven force, and the problem of sudden falling of the conveying roller 100 due to the failure of the magnetic driving mechanism 200 and other structures; and the cooperation of the supporting rod 300 and the annular groove 110 on the conveying roller 100 can also play a role of limiting the conveying roller 100 in the axial direction to avoid the left and right deviation of the conveying roller 100.

[0036] As preferred, the supporting rod 300 is provided in plurality, so as to improve the support, rigidity and limiting effect of the supporting rod 300.

When the workpiece leaves the conveying rollers 100, the conveying rollers 100 are reset, and the magnetic driving mechanisms 200 are reset synchronously with the conveying rollers 100 in the support mechanism 400. By arranging the support mechanism 400, the reliability of the conveying device can be improved.

[0041] Preferably, in the embodiment, the magnetic driving mechanisms 200 and the corresponding support mechanisms 400 are arranged outside the two side plates 510, so as to avoid the phenomenon that impurities interfere with the magnetic driving mechanisms 200 and the support mechanisms 400 during operation of the conveying device, protect the magnetic driving mechanisms 200 and the support mechanisms 400 to a certain extent, and prolong the service life.
