The rotating arm 221 rotates around the first rotating shaft, and the rotating arm 221 drives the outer cylinder 22 to be lifted and rotated, pouring the ground workpiece and abrasive into the feed port 321.

[0027] In some embodiments, such as Figure 1 , 4 As shown in Figures 5 and 6, the screening assembly 3 includes: a screening base frame 31, the bottom of which is connected to the main frame 11 via a vibrating spring 311, and a vibrating motor 312 is also provided at its bottom, which can drive the entire screening base frame 31 to vibrate; a vibrating frame 32, which is located above the screening base frame 31 and has the feed inlet 321 on it; a first screening section 33, which is located above the screening base frame 31 and is connected to the vibrating frame 32; and a second screening section 34, which is located above the screening base frame 31 and is connected to the first screening section 33, with the discharge port 35 located at the end of the second screening section 34. Specifically, in this embodiment, the abrasive and the workpiece are conveyed to the first screening section 33 by the vibration of the screening vibrating frame. After the first screening section 33 undergoes a first round of screening, it is conveyed to the second screening section 34, where a second screening is completed, so that the abrasive and the workpiece are completely separated.

[0028] In some embodiments, such as Figure 1 , 4As shown in Figures 5 and 6, the first screening unit 33 includes two first screening frames 331. A first magnetic drive roller 332 and a first follower roller 333 are rotatably arranged between the two first screening frames 331.

Specifically, the first motor 336 is connected to one end of the first magnetic drive roller 332 through a belt and a linkage wheel structure. The structure of the belt and linkage wheel is prior art and will not be described in detail here. The first motor 336 drives the first magnetic drive roller to rotate. The first magnetic drive roller will be magnetically attracted, so that the workpiece is driven by the first conveyor belt 334 and conveyed to the second conveyor belt 344. A first discharge circulation port 337 is provided below the first screening section 33. The first discharge circulation port 337 can guide the abrasive to the recycling component 5, while the abrasive that is not magnetically attracted is transported to the recycling component 5 through the first discharge circulation port 337 below the first screening section 33. The first discharge circulation port 337 can be connected to the top of the recycling component 5 through a structure such as a pipe to transport the abrasive to the top of the recycling component 5.

A second magnetic drive roller 342 and a second follower roller 343 are rotatably arranged between the two second screening frames 341. A second conveyor belt 344 is sleeved between the second magnetic drive roller 342 and the second follower roller 343. A second fixed frame 345 is arranged above the second screening frame 341. A second motor 346 is arranged on the second fixed frame 345. The output end of the second motor 346 is connected to the second magnetic drive roller 342. Specifically, after screening by the first screening section 33, most of the workpieces and abrasives have been separated. A small portion of abrasives is still squeezed between the workpieces and has not been separated. A buffer gap 347 is formed between the first screening section 33 and the second screening section 34. A second discharge circulation port 348 is arranged below the second screening section 34. The buffer gap 347 is connected to the second discharge circulation port 348. The recycling component 5 is located above the second discharge circulation port. Specifically, when the abrasive and the workpiece fall into the buffer gap 347, the workpiece will be magnetically attracted by the second magnetic drive roller 342 and transported on the second conveyor belt 344, while the abrasive will be transported to the recycling component 5 through the second discharge circulation port 348. Through the screening of the second screening section 34, the separation of the abrasive and the workpiece is completely realized.

[0030] In some embodiments, such as Figure 1 and 4 As shown, the recycling assembly includes a recycling slide bar 51 disposed below the main frame 11.

Specifically, the recycling drive mechanism is a motor-driven belt linkage structure, which is prior art and will not be described in detail here. In this embodiment, the recycling drive mechanism can drive the recycling conveyor belt 56 to rotate forward or reverse, and the recycling drive cylinder 57 drives the entire recycling conveyor belt 56 to approach the feeding assembly 6. The feeding assembly 6 is located on both sides of the recycling conveyor belt 56. Therefore, the recycling drive cylinder 57 drives the recycling conveyor belt 56 to move back and forth between the two feeding assemblies 6. At the same time, the recycling drive mechanism drives the conveyor belt to rotate forward or reverse so as to evenly distribute the abrasive on the two different feeding assemblies 6.

[0031] In some embodiments, such as Figure 1 and 2 As shown, the feeding assembly 6 includes a feeding cylinder 61 and a feeding hopper 62. The output end of the feeding cylinder 61 is rotatably connected to the feeding hopper 62. Two second bearing shafts are provided on the sub-frame 12, and two second rotating shafts 64 are rotatably provided on the two second bearing seats 63. The rear side of the top of the hopper is connected to the second rotating shafts 64, and the feeding cylinder 61 is located below the second rotating shafts 64. The feeding hopper 62 includes a hopper groove 621 and a feeding port 622, which are connected. Specifically, in this embodiment, the recycling conveyor belt 56 transports the abrasive to the hopper groove 621, and then the feeding cylinder 61 drives the feeding hopper 62 to rotate around the second rotating shaft 64. The abrasive located in the hopper groove 621 is discharged from the feeding port 622 and poured into the eddy current grinding assembly 2, realizing the recycling of the abrasive.
