[0002] During the processing and production of NdFeB permanent magnet materials, a circulating material cart is required to transfer the NdFeB permanent magnet materials. During the loading and unloading process of the NdFeB permanent magnet materials, the existing loading and unloading circulating material cart is not convenient for adjusting the loading and unloading height of the circulating material frame, and the lifting mechanism on the existing loading and unloading circulating material cart that is convenient for adjusting the loading and unloading height of the circulating material frame is integrated with the trolley, and the structure is bulky and inconvenient.

[0003] According to patent CN 216902524 U, a high-performance sintered NdFeB permanent magnet material loading and unloading transfer vehicle includes a transfer trolley and a lifting mechanism coordinated with the transfer trolley, wherein the lifting mechanism includes a rectangular concave box with an opening on the rear side, four first self-locking universal wheels and four adjustable casters fixedly arranged at the bottom of the rectangular concave box, a folding shutter protective cover slidably arranged in the opening, a vertical screw rod transmission-arranged on the inner side of the rectangular concave box, a moving seat transmission-connected to the vertical screw rod through a screw nut, a U-shaped fixed plate fixedly connected to the moving seat and slidably arranged on the outer side of the rear side of the rectangular concave box, and two longitudinal plug rods fixedly arranged on the rear side of the U-shaped fixed plate and plugged in with the transfer trolley.

[0004] The patent sets the lifting mechanism at the station where high-performance sintered NdFeB permanent magnet materials need to be taken and discharged. The NdFeB permanent magnet materials are loaded on the material turnover basket on the transfer cart.

[0015] 1. The high-performance sintered NdFeB permanent magnet material loading and unloading flow material cart places the material turnover frame on the first connecting plate through the lifting and clamping mechanism, and then starts the motor to rotate the first gear. Since the first gear is meshed with the second gear, the rotation of the first gear will cause the second gear to rotate, thereby causing the screw to rotate.

[0016] 2. The high-performance sintered NdFeB permanent magnet material loading and unloading flow material cart uses a fixing mechanism. Before using the device, rotate the rotating block to rotate the rotating shaft. The rotation of the rotating shaft will cause the top of the third connecting plate to move away from the bottom of the limit plate. Then the guide rod will move downward through the elastic force of the second spring, thereby moving the rubber plate downward so that the bottom of the rubber plate is tightly attached to the ground and the device is fixed. Before moving, pull the limit plate by hand to pull the limit plate to the bottom of the third connecting plate. Then rotate the rotating shaft in the opposite direction so that the third connecting plate is located at the bottom of the limit plate. Then release the limit plate so that the top of the bottom of the third connecting plate is against the bottom of the limit plate, so that the rubber plate is driven off the ground.
