[0032] Specifically, the control mechanism 4 includes a first transmission shaft 41, a first mounting seat 42, a second mounting seat 43 and a third mounting seat 44. The first transmission shaft 41 passes through the side wall of the box body 1, the first mounting seat 42, the second mounting seat 43 and the third mounting seat 44, and one end of the first transmission shaft 41 is connected to the output end of the motor 3. A first lead screw 45 is provided between the third mounting seat 44 and the heat insulation board 6. The two ends of the first lead screw 45 are rotatably connected to the upper end of the third mounting seat 44 and the lower end of the heat insulation board 6 respectively. A second lead screw 46 is provided between the second mounting seat 43 and the heat insulation board 6. The second lead screw 46 is provided between the second mounting seat 43 and the heat insulation board 6. The two ends of 6 are rotatably connected with the upper end of the second mounting seat 43 and the lower end of the heat insulation plate 6 respectively, and the supporting device 7 is slidably installed on the first lead screw 45 and the second lead screw 46. The second transmission shaft 8 is rotatably installed on the upper end of the first mounting seat 42. The second transmission shaft 8 passes through the heat insulation plate 6 and the second box cover 22, and the end of the second transmission shaft 8 away from the first mounting seat 42 is fixedly connected to the spur gear 23. The first transmission shaft 41 is located between the first mounting seat 42 and the second mounting seat 43 and is close to the first mounting seat 42. A first bevel gear 47 is provided on the first transmission shaft 41 at the first mounting seat A third bevel gear 48 is provided between the seat 42 and the second mounting seat 43 and on a side close to the second mounting seat 43, a fifth bevel gear 49 is provided on an end of the first transmission shaft 41 away from the third mounting seat 44, a second bevel gear 81 is provided on an end of the second transmission shaft 8 close to the first mounting seat 42, a fourth bevel gear 461 is provided on an end of the second lead screw 46 close to the second mounting seat 43, a sixth bevel gear 451 is provided on an end of the first lead screw 45 close to the third mounting seat 44, the first bevel gear 47 and the second bevel gear 81, the third bevel gear 48 and the fourth bevel gear 461, and the fifth bevel gear 4 9 and the sixth bevel gear 451 are tightly meshed respectively, the sizes and the number of teeth of the first bevel gear 47, the fourth bevel gear 461 and the sixth bevel gear 451 are respectively smaller than the sizes and the number of teeth of the second bevel gear 81, the third bevel gear 48 and the fifth bevel gear 49, so as to control different transmission ratios, the supporting device 7 comprises a bottom plate 71, a supporting column 72 is fixedly mounted on the upper end of the bottom plate 71, the supporting column 72 passes through the insulation board 6, and a supporting claw 73 is arranged at one end of the supporting column 72 away from the bottom plate 71, which is used to support the furnace body 52 during heating and to assist the furnace body 52 to rise out of the box when smelting is complete.

[0033] By adopting the above technical solution, the motor 3 is started to drive the first transmission shaft 41 to rotate, so that the first bevel gear 47, the third bevel gear 48 and the fifth bevel gear 49 rotate, and the second transmission shaft 8, the first lead screw 45 and the second lead screw 46 rotate through the gear meshing transmission. The rotation of the second transmission shaft 8 drives the spur gear 23 to rotate, thereby controlling the opening and closing of the box cover 2. Since the first lead screw 45 and the second lead screw 46 are connected to the bottom plate 71 through threads, the rotation of the first lead screw 45 and the second lead screw 46 causes the bottom plate 71 to move in the vertical direction, thereby The entire support device 7 slides in the vertical direction. Since the sizes and the number of teeth of the first bevel gear 47, the fourth bevel gear 461 and the sixth bevel gear 451 are respectively smaller than the sizes and the number of teeth of the second bevel gear 81, the third bevel gear 48 and the fifth bevel gear 49, and the sizes and the number of teeth of the third bevel gear 48 and the fifth bevel gear 49, the fourth bevel gear 461 and the sixth bevel gear 451 are equal, the two groups of support devices 7 can be controlled to rise and fall synchronously. By controlling the different transmission ratios, when the box cover 2 is fully opened, the furnace body 52 can be pushed out of the box body 1 by the support device 7.

[0034] Specifically, the heating mechanism 5 includes a first coil 51, a furnace body 52 and a heating unit 53. The furnace body 52 is arranged on the supporting claw 73. The first coil 51 is wound around the surface of the furnace body 52 and a gap is left between the first coil 51 and the surface of the furnace body 52. ​​The heating unit 53 is arranged on the outside of the first coil 51. The heating unit 53 includes a servo motor 531. The output end of the servo motor 531 is provided with a third screw 532. A slider 533 is slidably provided on the third screw 532.

The distance between the upper and lower ends of the first coil 51 is greater than the distance between the two ends of the second coil 534.

[0035] By adopting the above technical solution, the first coil 51 first preheats all the aluminum materials in the furnace body 52, and the second coil 534 gradually heats and smelts the aluminum materials in the furnace body 52 from bottom to top. Since the small aluminum parts at the bottom are easier to melt than the large aluminum parts at the top, 534 is first used to heat the aluminum parts at the bottom. After the aluminum parts at the bottom are melted, 534 is moved upward to heat the large aluminum materials above, thereby improving the melting efficiency and saving energy.

[0036] Specifically, a mesh 521 is provided in the middle of the furnace body 52 for separating aluminum profiles of different sizes, so that small aluminum profiles that are easy to melt are deposited at the bottom of the furnace body 52, while larger aluminum profiles are above the mesh 521, and gradually heated from bottom to top by the second coil 534, which can improve the heating efficiency. A temperature sensor 522 is provided on the outer wall of the furnace body 52 for transmitting signals to the servo motor 531 to control the operation of the servo motor 531. The melting point of aluminum is 660°C. When the temperature of the lower part of the furnace body 52 rises to 700°C, the temperature sensor 522 sends a signal to control the servo motor 531 to start, drive the third screw 532 to rotate, and make the slider 533 slide away from the servo motor 531, so that the second coil starts to heat the aluminum profile in the upper part of the furnace body 52.

[0037] Specifically, all the mechanisms are made of high temperature resistant materials. Since the melting point of aluminum is 660° C., the temperature of the working environment is relatively high. The use of high temperature resistant materials can extend the service life of the present invention.

[0038] Working principle: When in use, the motor 3 is started to rotate forward, driving the first transmission shaft 41 to rotate, so that the first bevel gear 47, the third bevel gear 48 and the fifth bevel gear 49 rotate, and through the gear meshing transmission, the second transmission shaft 8, the first lead screw 45 and the second lead screw 46 are driven to rotate. The rotation of the second transmission shaft 8 drives the spur gear 23 to rotate, thereby controlling the opening of the box cover 2. The rotation of the first lead screw 45 and the second lead screw 46 causes the support device 7 to slide in the direction close to the box cover 2, so that the furnace body 52 is pushed out of the box body 1. At this time, the aluminum material to be smelted is added. After the filling is completed, the motor 3 is started to reverse, so that the furnace body 52 returns to the original position in the box body 1, the box cover 2 is closed, the power is turned on, and the aluminum material begins to be heated and melted. The first coil 51 first preheats all the aluminum materials in the furnace body 52. ​​Since the small aluminum parts at the bottom are easier to melt than the large aluminum parts at the top, the second coil 534 gradually heats and smelts the aluminum materials in the furnace body 52 from bottom to top. A leakage net is provided in the middle position inside the furnace body 52 521 is used to separate aluminum profiles of different sizes, so that small aluminum profiles that are easy to melt are deposited at the bottom of the furnace body 52, while larger aluminum profiles are above the filter 521. The second coil 534 is used to heat the aluminum profiles gradually from bottom to top, and the small aluminum profiles are heated first. A temperature sensor 522 is provided on the outer wall of the furnace body 52, which is used to transmit signals to the servo motor 531 to control the operation of the servo motor 531. The melting point of aluminum is 660°C. When the temperature of the lower part of the furnace body 52 rises to 700°C, the small aluminum profiles are completely melted. The temperature sensor 522 sends a signal to control the servo motor 531 to start, drive the third lead screw 532 to rotate, and make the slider 533 slide away from the servo motor 531, so that the second coil starts to heat the aluminum profiles in the upper part of the furnace body 52, and the first coil 51 keeps the aluminum profiles in the lower part of the furnace body 52 completely heated. After a certain period of time, when the aluminum profiles are completely melted, the motor 3 is started to rotate forward, so that the furnace body 52 is ejected out of the box 1, and the subsequent process is carried out after the staff takes it out.

[0039] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention.

The rotation of the second transmission shaft (8) drives the spur gear (23) to rotate, thereby controlling the opening of the box cover (2). The rotation of the first lead screw (45) and the second lead screw (46) causes the support device (7) to slide in a direction close to the box cover (2), so that The furnace body (52) is pushed out of the box body (1), and the aluminum material to be smelted is added. After the filling is completed, the motor (3) is started to reverse, so that the furnace body (52) returns to its original position in the box body (1). The box cover (2) is closed, and the power is turned on to start heating and melting the aluminum material. The first coil (51) first preheats all the aluminum material in the furnace body (52). Since the small aluminum pieces at the bottom are easier to melt than the large aluminum pieces at the top, the second coil (534) gradually heats and smelts the aluminum material in the furnace body (52) from bottom to top. The middle position of the furnace body (52) is provided with a A mesh (521) is provided to separate aluminum profiles of different sizes, so that small aluminum profiles that are easy to melt are deposited at the bottom of the furnace body (52), while larger aluminum profiles are above the mesh (521). The second coil (534) is used to heat the small aluminum profiles gradually from bottom to top, and the small aluminum profiles are heated first. A temperature sensor (522) is provided on the outer wall of the furnace body (52) to transmit a signal to the servo motor (531) to control the operation of the servo motor (531). The melting point of aluminum is 660°C. When the temperature of the lower part of the furnace body (52) rises to 700°C, the small aluminum profiles melt. When the furnace is completely heated, the temperature sensor (522) sends a signal to control the servo motor (531) to start, driving the third lead screw (532) to rotate, so that the slider (533) slides in a direction away from the servo motor (531), so that the second coil starts to heat the aluminum material in the upper part of the furnace body (52), and the first coil (51) keeps the aluminum material in the lower part of the furnace body (52) completely heated. After a certain period of time, when the aluminum material is completely melted, the motor (3) is started to rotate forward, so that the furnace body (52) is ejected out of the box body (1), and the subsequent process is carried out after the staff takes it out.
