[0033] Step 2: When the magnetic material is heated to the Curie temperature, the magnetic material will be demagnetized and fall from the iron plate 13. After being demagnetized, the magnetic material will fall on the surface of the metal conveyor belt 6 and will immediately contact the temperature detector 10 on the surface of the metal conveyor belt 6 to detect the temperature.

[0034] Step three: When the magnetic material falls on the metal conveyor belt 6, it will press the lower elastic plate 9 to deform. After the lower elastic plate 9 is deformed, it will contact the lower push switch 8.

[0035] Working principle: during detection, the heating ring 11 will continuously heat the magnetic material attracted under the iron plate 13. When the magnetic material is heated to the Curie temperature, the magnetic material will be demagnetized and fall from the iron plate 13. After demagnetization, the magnetic material will fall on the surface of the metal conveyor belt 6 and contact the thermometer 10 on the surface of the metal conveyor belt 6 at the first time, and detect the temperature, so that the thermometer 10 can detect the temperature of the magnetic material at the first time without detecting the temperature inside the device, and then accurately detect the Curie temperature of the magnetic material.

At this time, the new magnetic material has not reached the Curie temperature, so the new magnetic material will be absorbed on the iron plate 13. At this time, the heating coil 11 will heat and detect the next magnetic material again, so that the automatic feeding of the magnetic material can be realized without manual operation by the workers, so as to prevent the workers from being scalded.

[0037] When the magnetic material reaches the Curie temperature and falls on the metal conveyor belt 6 and is driven to be discharged, the magnetic material will move to the discharge plate 31 and slide downward along the discharge plate 31 by gravity. When the magnetic material slides to the right elastic plate 34, it will be blocked by the right elastic plate 34, and the right elastic plate 34 will slowly deform and shrink into the discharge plate 31. During the time when the magnetic material is blocked, it will be blown by the fan group 33 for heat dissipation, which can quickly cool the magnetic material and facilitate the subsequent handling of the magnetic material. The right elastic plate 34 can also block and buffer the magnetic material through elastic force to prevent the magnetic material from directly sliding through the discharge plate 31, thereby causing collision and damage to the magnetic material.

[0038] When the heating coil 11 heats the magnetic material, the movable plate 43 below the heating coil 11 will block the heat to prevent the heat from overflowing through the gap below, resulting in a reduced heating effect of the magnetic material. When the magnetic material reaches the Curie temperature, it will demagnetize and fall on the movable plate 43. The weight of the iron plate 13 will decrease due to the fall of the magnetic material, and then it will reset and move upward under the action of the spring below the fixed plate 12. After the iron plate 13 moves upward, it will contact the upper push switch 411. The upper push switch 411 will generate an electrical signal to the motor 41, so that the motor 41 starts and drives the gear 1 42 to rotate. The gear 1 42 will drive the movable plate 43 to move through the upper teeth 44, and the movable plate 4 The movement of the movable plate 43 will drive the second gear 49 to rotate through the lower teeth 45, and the second gear 49 will drive the slide plate 46 to move toward the magnetic material through the teeth 1 48, and the magnetic material will stay in the original position under the limit of the heating ring 11, and after the moving plate 43 moves, the magnetic material will fall on the slide plate 46 moving toward the magnetic material, and when the magnetic material falls on the slide plate 46, the two clamping plates 47 will be pressed by gravity to push the torsion spring to rotate, so that the two clamping plates 47 are slowly opened and the magnetic material slowly falls on the metal conveyor belt 6, so that both the magnetic material and the metal conveyor belt 6 can be protected to prevent the magnetic material from hitting the metal conveyor belt 6, causing damage to both parties.
