[0013] The working principle and beneficial effects of the present invention are:

[0014] 1. By setting up the coordination of electromagnetic heating coils and other parts, the electromagnetic heating coils are started. The operation of the electromagnetic heating coils will generate an alternating magnetic field around them, so that the alternating magnetic field will generate eddy currents in the ladle. When the eddy currents flow inside the metal, they will generate heat, thereby making the ladle itself hot. In this way, there is no need for flame heating, thereby reducing energy loss and optimizing the surrounding working environment;

[0015] When the ladle is running, the third drive motor can be started, and the output end of the third drive motor drives the reciprocating screw to rotate slowly, thereby driving the sliding seat to drive the electromagnetic heating ring to move back and forth, so that the magnetic field generated by the operation of the electromagnetic heating ring can be evenly distributed inside the ladle, and the ladle does not need to be heated slowly from bottom to top, thereby improving the efficiency of baking the ladle;

[0016] 2. By setting up the cooperation of the fourth drive motor and other parts, when the sliding seat drives the electromagnetic heating coil to move, the fourth drive motor is started, and the output end of the fourth drive motor can be forward and reversed. When the output end of the fourth drive motor rotates forward, it can drive the winding roller to release the wire, so that the electromagnetic heating coil can always be powered. At the same time, when the electromagnetic heating coil moves down to the maximum position and resets, the output end of the fourth drive motor reverses to rewind the wire, thereby realizing the function of winding and releasing the wire, thereby avoiding the entanglement of the wire during use, and thus improving the overall practicality of the device;

[0017] 3. By setting an auxiliary folding component, the output end of the second driving motor drives the slider to move away from the center position of the ladle. When the slider is moving, the spur gear contacts the spur rack, and the spur gear can be driven by the spur rack to drive the rotating shaft to rotate through the connecting block, thereby driving the connecting seat to rotate. When the slider stops moving, the connecting seat rotates ninety degrees, thereby realizing the folding of the U-shaped frame and the electromagnetic heating ring, so that the electromagnetic heating ring can be moved out without lifting the insulation cover to a higher position, thereby improving the overall practicality of the device;

[0018] Before the electromagnetic heating coil is used, the slider can be moved to the center of the ladle, so that the electromagnetic heating coil can be in the center of the ladle, thereby ensuring that the magnetic field generated by the electromagnetic heating coil can be evenly distributed inside the ladle, thereby improving the uniformity of heating the ladle;

[0019] 4. By setting up a lifting component, when the connecting block drives the connecting seat to rotate and fold through the rotating shaft, the electromagnetic heating coil is reset to the initial state, and the connecting block drives the disc to rotate, and then the rotary push column drives the return rod to drive the power rod to move upward, thereby pushing the fixed frame upward through the movable block, so that the wire wound on the winding roller always maintains a certain length with the connected part on the electromagnetic heating coil, thereby avoiding the entanglement of the wire during use, thereby further improving the overall practicality of the device.
