Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron permanent magnet material processing technology, specifically a grinding device for processing neodymium iron boron permanent magnet materials. Background Technology

[0002] Neodymium iron boron (NdFeB) is a permanent magnet material that is rapidly developing and widely used due to its excellent performance, abundant raw materials, and low price. It is mainly used in electroacoustic devices, instruments, automobiles, petrochemicals, nuclear magnetic resonance, magnetotherapy and health care, and other fields that are closely related to our daily lives. Its main production processes include batching, smelting, powdering, molding, sintering and tempering, magnetic testing, grinding, cutting, and electroplating. When processing NdFeB, the material needs to be ground. Chinese Patent Publication No. CN217962847U discloses a magnetic material grinding device, including a housing, a first grinding chamber, a through cavity, and a second grinding chamber. The two ends of the through cavity are respectively connected to the first and second grinding chambers. A feed hopper is fixedly connected to the top of the housing. This invention allows the magnetic material to be discharged intermittently and evenly by the reciprocating left and right movement of the sealing plate, ensuring the grinding effect. By performing coarse and fine grinding on the magnetic material, a good grinding effect is achieved.

[0003] In the prior art, when grinding neodymium iron boron permanent magnet materials, material residue is easily left on the side wall of the device, making it inconvenient to open the outer shell of the device and thus difficult to clean the residue inside, resulting in material waste and affecting the next grinding. To address this, we propose a grinding device for processing neodymium iron boron permanent magnet materials. Utility Model Content

[0006] As a further description of the above technical solution: The lifting mechanism also includes connecting blocks symmetrically fixed to the bottom of the threaded disc, and a connecting groove is provided in the center of the top of the top plate.

[0007] As a further description of the above technical solution: The slide rod passes through the top of the top plate and is slidably connected to the top plate, and the screw passes through the top of the top plate.

[0008] As a further description of the above technical solution: Both the grinding motor and the drive motor are electrically connected to the control switch, and the driving gear and the driven gear are meshed together.

[0009] As a further description of the above technical solution: The connecting block is connected to the inside of the connecting groove, and the grinding motor is located inside the fixing frame.

[0010] As a further description of the above technical solution: The top of the cover plate is symmetrically provided with an intermittent feeding mechanism. The intermittent feeding mechanism includes a storage box symmetrically fixed to the top of the cover plate. A discharge port is opened through the middle of the bottom of the storage box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This grinding device for processing neodymium iron boron permanent magnet materials works by starting a drive motor, which drives the drive gear to rotate, thereby causing the driven gear to rotate and driving the threaded disc to rotate. The threaded disc is screwed to a screw, and when the threaded disc rotates, the screw moves, which in turn drives the fixed frame to rise, and the cover plate to rise, thereby raising the grinding disc. This makes it easy to open the grinding cylinder, which facilitates rinsing the outside of the grinding disc and the inside of the grinding cylinder to prevent residue, collect the material, avoid waste, and prevent it from affecting subsequent grinding.

[0013] This grinding device for processing neodymium iron boron permanent magnet materials works by placing the material inside the storage box, starting the rotating motor to drive the turntable to rotate, causing the extrusion shaft to move in a circular motion and extrude the side wall of the through groove. This causes the partition to move back and forth, periodically aligning the through opening with the discharge port, thus causing the material to fall periodically. This avoids too much material entering at once, which would lead to insufficient grinding and improves the practicality of the device. Attached Figure Description

[0019] This utility model provides a grinding device for processing neodymium iron boron permanent magnet materials. It facilitates rinsing of the outer side of the grinding disc and the inner side of the grinding cylinder to prevent residue, collects material to avoid waste, and avoids affecting subsequent grinding. Please refer to [link / reference]. Figure 1 It includes a base plate 100, a support rod 200, a top plate 300, a control switch 400, and a support column 500; Please refer to it again. Figure 1 The base plate 100 is used to install the support rod 200, the top plate 300, the control switch 400, and the support column 500; Please refer to it again. Figure 1 The support rod 200 is fixed at the top four corners of the base plate 100, the top plate 300 is fixed at the top of the support rod 200, the control switch 400 is fixed at the top edge of the top plate 300, and the support column 500 is evenly fixed at the top of the base plate 100. Please refer to it again. Figure 2 A grinding cylinder 510 is fixed to the top of the support column 500. A discharge port 511 is opened through the middle of the bottom of the grinding cylinder 510.

Figure 3 The top of the cover plate 520 is connected to a lifting mechanism 600. The lifting mechanism 600 includes a fixing frame 610 fixed to the middle of the top of the cover plate 520. A sliding rod 620 is symmetrically fixed to the top of the cover plate 520. A screw 630 is fixed to the middle of the top of the fixing frame 610. Please refer to it again. Figure 3 A threaded disc 640 is screwed to the outer wall of the screw 630. A driven gear 650 is fixed to the outer wall of the threaded disc 640.

A drive gear 680 is fixed to the end of the output shaft of the drive motor 670.

[0020] In summary, by starting the drive motor 670, the driving gear 680 rotates, which in turn causes the driven gear 650 to rotate, driving the threaded disc 640 to rotate. The threaded disc 640 is screwed to the screw 630. When the threaded disc 640 rotates, the screw 630 moves, which in turn causes the fixed frame 610 to rise, and the cover plate 520 to rise, thereby raising the grinding disc 550. This makes it easier to open the grinding cylinder 510, allowing for rinsing of the outside of the grinding disc 550 and the inside of the grinding cylinder 510 to prevent residue, collect the material, avoid waste, and prevent interference with subsequent grinding.

[0021] Please refer to it again. Figure 4The lifting mechanism 600 also includes connecting blocks 641 symmetrically fixed to the bottom of the threaded disc 640, and a connecting groove 642 is provided in the middle of the top of the top plate 300.

[0022] Please refer to it again. Figure 3 The slide rod 620 passes through the top of the top plate 300 and is slidably connected to the top plate 300. The screw rod 630 passes through the top of the top plate 300.

[0023] Please refer to it again. Figure 3 The grinding motor 530 and the drive motor 670 are both electrically connected to the control switch 400, and the driving gear 680 and the driven gear 650 are meshed together.

[0024] Please refer to it again. Figure 3 The connecting block 641 is connected to the inside of the connecting groove 642, and the grinding motor 530 is located inside the fixing frame 610.

[0025] Please refer to it again. Figure 5 An intermittent feeding mechanism 700 is symmetrically arranged on the top of the cover plate 520. The intermittent feeding mechanism 700 includes a storage box 710 symmetrically fixed to the top of the cover plate 520. A discharge port 720 is opened through the middle of the bottom of the storage box 710. A partition 730 is slidably slidably slidably through one side of the storage box 710. A through opening 740 is opened through the top of the partition 730. A through groove 750 is opened through the top edge of the partition 730. A rotating motor 760 is fixed to one side of the storage box 710. A turntable 770 is fixed to the end of the output shaft of the rotating motor 760. An extrusion shaft 780 is fixed to the bottom edge of the turntable 770.

[0026] Please refer to it again. Figure 5 The rotating motor 760 is electrically connected to the control switch 400. The extrusion shaft 780 is located inside the through groove 750, and the deflection circumference diameter of the extrusion shaft 780 is smaller than the length of the through groove 750.

[0027] In summary, by placing the material inside the storage box 710, starting the rotating motor 760, driving the turntable 770 to rotate, and causing the extrusion shaft 780 to move in a circular motion, the side wall of the through groove 750 is extruded, thereby causing the partition plate 730 to move back and forth, so that the through opening 740 periodically aligns with the discharge port 720, thereby causing the material to fall periodically, avoiding too much material entering at once, which would lead to insufficient grinding, and improving the practicality of the device.

[0028] In practical use, when grinding, those skilled in the art pour the material into the storage box 710, and start the rotary motor 760 and grinding motor 530 by controlling the switch 400. The start of the rotary motor 760 drives the turntable 770 to rotate, causing the extrusion shaft 780 to move circumferentially, extruding the sidewall of the through groove 750. This causes the partition 730 to move back and forth, periodically aligning the through opening 740 with the discharge port 720, thus causing the material to periodically descend. After grinding is complete, the rotary motor 760 and grinding motor 530 are turned off. Motor 530 starts the drive motor 670, which drives the drive gear 680 to rotate, thereby causing the driven gear 650 to rotate, which in turn drives the threaded disc 640 to rotate. The threaded disc 640 is screwed to the screw 630. When the threaded disc 640 rotates, the screw 630 moves, which in turn drives the fixed frame 610 to rise, and the cover plate 520 to rise, thereby raising the grinding disc 550, making it easier to open the grinding cylinder 510 and to wash the outside of the grinding disc 550 and the inside of the grinding cylinder 510.
