Description

Technical Field

[0001] The utility model belongs to the technical field of NdFeB sorting machines, and particularly relates to an automatic feeding device for an NdFeB sorting machine. Background Art

[0002] The NdFeB sorting machine, as a kind of magnetic separation equipment, mainly utilizes the strong magnetism of the high-performance rare earth permanent magnet material NdFeB (neodymium iron boron) to realize the magnetic separation of materials. The NdFeB sorting machine generates a strong magnetic field through the NdFeB magnetic system inside it. When the material passes through the sorting machine, magnetic materials (such as iron powder, ferromagnetic impurities, etc.) are attracted by the magnetic field and adsorbed on the magnetic components of the sorting machine, while non-magnetic materials are not affected by the magnetic field and continue to pass through the sorting machine, thus realizing the separation of magnetic materials and non-magnetic materials.

[0003] In the prior art, for example, the Chinese utility model patent with the authorization announcement number CN203778351 U discloses an automatic feeding device for an NdFeB workpiece sorting machine. Its structure includes a frame, on which there is a circular turntable, a detection device and a sorting device arranged along the edge of the circular turntable. The frame is provided with a feeding conveyor belt and a stepping motor for driving the feeding conveyor belt to run. The side of the feeding conveyor belt is tangent to the side of the circular turntable, and the upper surface of the feeding conveyor belt is flush with the upper surface of the circular turntable. Above the feeding conveyor belt, a first stop block and a second stop block are arranged in sequence along the conveying direction. There is an angle of 30 - 45° between the first stop block and the feeding conveyor belt, and an angle of 45 - 60° between the second stop block and the feeding conveyor belt. The end of the second stop block is located at the position where the feeding conveyor belt is tangent to the circular turntable. The above feeding device solves the problems of workpiece overlap and non-constant feeding frequency during the feeding of NdFeB workpieces, and thus improves its detection accuracy and detection efficiency.

[0004] However, the above prior art uses two groups of stop blocks to block and disperse the NdFeB workpieces during feeding. However, when the stop blocks control the NdFeB workpieces, they can only control the continuity of the feeding of NdFeB workpieces, and cannot completely control the effect of avoiding overlap when the NdFeB workpieces are fed, resulting in the phenomenon of overlap and blockage still occurring during the feeding process of the NdFeB workpieces, and reducing the feeding efficiency of the NdFeB workpieces. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an automatic feeding device for a neodymium iron boron sorting machine, aiming to solve the problem that the above-mentioned disclosed patent uses two sets of stoppers to block and disperse the feeding of neodymium iron boron workpieces. However, when the stoppers are used to control the neodymium iron boron workpieces, they can only control the continuity of the feeding of the neodymium iron boron workpieces, and cannot completely control the effect of avoiding overlap when the neodymium iron boron workpieces are fed, resulting in the phenomenon of overlap blockage still occurring during the feeding and conveying process of the neodymium iron boron workpieces, and reducing the feeding and conveying efficiency of the neodymium iron boron workpieces.

The top end of the fixing rod is movably connected to a telescopic rod, and the top end of the telescopic rod is connected to a baffle.

[0028] Preferably: A stop block 11 is installed on the surface of the substrate 2 near the feeding belt 9. The stop block 11 is inclined with respect to the feeding belt 9.

[0029] During specific use, the sorter 4 belongs to the prior art. For the specific working principle, refer to the published patent: CN203778351U;

[0030] Preferably: The threaded rod 13 is threadedly connected to the side plate 12. The threaded rod 13 forms a rotating structure through the opening on the surface of the positioning block 14 with the rotating block 15.

[0031] During specific use, by adjusting the screw rod 13 up and down, it is convenient to drive the seasoning plate 16 to move.

[0032] Preferably: The seasoning plate 16 is made of stainless steel, and the seasoning plate 16 and the opening on one side of the guide plate 17 form a sliding connection structure.

[0033] During specific use, by sliding the seasoning plate 16 along the opening on one side of the guide plate 17, it is convenient to adjust the height of the seasoning plate 16 and control the spacing.

[0034] Preferably: A fixed rod 18 is installed on the surface of the substrate 2 close to the feeding belt 9. The top of the fixed rod 18 is movably connected to a telescopic rod 19, and the top of the telescopic rod 19 is connected to a baffle 20.

[0035] During specific use, by using the baffle 20, it is convenient to limit the neodymium iron boron workpiece, avoid the phenomenon of the neodymium iron boron workpiece falling during the feeding process, and improve the feeding efficiency.

[0036] Preferably: A movable rod 21 is penetrated and connected to the outer side wall of the fixed rod 18. The other end of the movable rod 21 is connected to a linkage plate 22.

The specific process is to rotate the threaded rod 13, causing the threaded rod 13 to move up and down along the side plate 12. During this process, the rotating block 15 at the bottom end of the threaded rod 13 rotates along the opening on the surface of the positioning block 14, thereby driving the seasoning plate 16 to slide along the opening inside the guide plate 17. At this time, the workpieces enter the feeding belt 9 in sequence through the vibrating disk. Then, the overlapping neodymium iron boron workpieces are controlled and dispersed by the adjusted seasoning plate 16. After that, the arranged neodymium iron boron workpieces are transported to the circular turntable 3 through the baffle 11. Then, detection and sorting are carried out, so as to make the feeding of the neodymium iron boron workpieces constant, avoid overlapping at the same time, and ensure the subsequent detection efficiency. Additionally, by pulling the movable rod 21, then sliding the telescopic rod 19 along the opening on the surface of the fixed rod 18, the baffle 20 is driven to rise, making the baffle 20 exceed the highest point of the feeding belt 9. Then, release the movable rod 21. At this time, the compressed linkage spring 23 rebounds, driving the pin 24 on one side of the linkage plate 22 to fit into the opening on one side of the telescopic rod 19, facilitating the stable installation of the baffle 20, and thus avoiding the phenomenon of the neodymium iron boron workpieces falling during the feeding process.
