The fully automatic magnet grinding machine according to claim 1, characterized in that, The cylinder (3) includes a cylinder body (301) fixedly connected to the bottom of the grinding machine box (2), a rotating plate (302) rotatably connected to one end of the cylinder body (301), an elastic element (303) fixedly connected to the end of the cylinder body (301) away from the rotating plate (302), and a movable plate (304) slidably connected inside the cylinder body (301).

3. The fully automatic magnet grinding machine according to claim 2, characterized in that, The electromagnet (4) includes a cylinder (401) fixedly connected to the rotating plate (302) and a dial plate (402) evenly arranged on the cylinder (401) in a circular pattern. The collection box (5) is provided with a push switch (7) for controlling the on and off of the electromagnet (4) circuit.

4. The fully automatic magnet grinding machine according to claim 3, characterized in that, A push rod (1151) is fixed on the push plate (115). The push rod (1151) moves against the movable plate (304). The lower opening (12) of the cylinder (3) includes a first material inlet (121) and a second material inlet (122). The cylinder (3) is connected to the first collection trough (501) through the first material inlet (121) and to the second collection trough (502) through the second material inlet (122).

5. The fully automatic magnet grinding machine according to claim 4, characterized in that, The spray assembly includes a water tank (6) fixed on a cylinder (3), a water pump (601) fixed on the water tank (6), a drain pipe (602) connected to the water outlet of the water pump (601), and a rotating nozzle (603) set at the end of the drain pipe (602). The rotating nozzle (603) is set inside the grinding machine box (2), and the water pump (601) is placed inside the water tank (6).

6. The fully automatic magnet grinding machine according to claim 5, characterized in that, The upper side of the cylinder (3) is provided with a communication port (14) that is connected to the bottom of the water tank (6). The movable plate (304) can block the communication port (14) when it is not moved by force.

7. A method of using the fully automatic magnet grinding machine according to claim 6, characterized in that, Includes the following steps: S1: Place the magnet to be polished inside the grinding machine box (2), close the door of the grinding machine box (2) and start the equipment; S2: The water pump (601) is started and water is sprayed into the grinding machine box (2) through the rotating nozzle (603) to suppress dust. The grinding machine body grinds the magnet simultaneously, and the waste chips flow into the cylinder (3) through the feed port with the water. S3: Magnetic waste is attracted by electromagnet (4), and the falling water impacts the deflector (402), causing electromagnet (4) to rotate and evenly attract magnetic waste. Non-magnetic waste falls into the first collection tank (501) through the first feed port (121); S4: After the magnet is polished, the swing plate (13) is pressed down, the upper baffle (8) and the lower baffle (10) are closed respectively to the feed port and the first feed port (121), the electromagnet (4) is de-energized and releases the magnetic waste, the magnetic waste falls on the inner wall of the bottom of the cylinder (3) and the lower baffle (10), ensuring the electromagnet (4)'s ability to adsorb magnetic waste during subsequent work; The lead screw (111) rotates, thereby driving the push plate (115) to push the magnetic waste to the second feed port (122). The movable plate (304) no longer blocks the second feed port (122) and the connecting port (14). The magnetic waste falls into the second collection tank (502), and the water in the water tank (6) washes away the residual waste through the connecting port (14). S5: Finally, the force applied to the swing plate (13) is released, and the swing plate (13) is reset under the action of the torsion spring, ready for the next round of magnet processing and polishing.
