[0002] Melting refers to the process in which the kinetic energy of the thermal motion of molecules increases when the temperature rises, resulting in the destruction of crystallization and the transformation of the material from the crystalline phase to the liquid phase. It is a first-order phase transition with an increase in enthalpy, entropy and volume. When metals are melted, a metal melting furnace is required for melting processing.

[0003] For example, a metal melting furnace with the application publication number "CN10701420A" can automatically and conveniently realize the lifting and lowering of the tray, and then can ensure that small metal parts can be stably placed at the bottom of the furnace for melting, and has strong stability. However, the metal melting furnace requires the operator to manually put the metal into the melting furnace, which requires the operator to measure the amount of metal entering, which increases the workload of the operator. At the same time, after the melting of the metal melting furnace is completed, the processed metal cannot be discharged from the melting furnace, and the operator needs to manually collect the molten metal inside the melting furnace, which increases the working time of the metal melting furnace, thereby reducing the working efficiency of the metal melting furnace.

The above method can make it more convenient for the operator to collect and organize the molten metal, which reduces the time required for cleaning the metal melting furnace, thereby improving the working efficiency of the metal melting furnace.

[0026] Working principle:

[0027] When a metal melting furnace is needed to melt metal:

[0028] Metal charging stage:

[0029] First, the operator pours the metal to be molten into the feed pipe 5, and then the operator rotates the knob 401, the knob 401 drives the incomplete gear 402 to rotate, the incomplete gear 402 drives the gear 403 to rotate, the gear 403 drives the torque spring 405 to deform and drives the first slider 406 to move, the first slider 406 drives the second connecting rod 407 to move, the second connecting rod 407 drives the third connecting rod 410 to move, the third connecting rod 410 drives the first baffle 408 and the second baffle 409 to move at the same time, and the first The baffle 408 and the second baffle 409 alternately block the feed pipe 5, so that only a small portion of the metal falls vertically into the furnace body 2 each time.
