[0025] As Figures 1 - 2 shown, mounting holes 101 are opened on the upper surface of the base 1. A controller 201 is fixedly connected to the front surface of the heating box 2. The controller 201 is electrically connected to the resistance wire heating plate 203. A box door 202 is hinged to the front surface of the heating box 2.

[0026] In this embodiment, the controller 201 is used to connect to an external power supply to control the resistance wire heating plate 203. The use of the controller 201 is a mature prior art and will not be elaborated in this article. The mounting holes 101 are used to cooperate with threaded components to connect to the ground, improving the stability of the device.

[0027] As Figures 3 - 4As shown in the figure, the adjustment module 4 includes a pedestal bearing 401, which is fixedly installed on the inner wall of the heating box 2. The number of pedestal bearings 401 is four. A guide rod 402 is fixedly connected to the inner ring part of the pedestal bearing 401, and a double-headed lead screw 403 is fixedly connected to the inner ring part of the pedestal bearing 401. A first reduction box 404 is fixedly connected to the outer surface of the heating box 2, and a first stepping motor 405 is fixedly connected to the upper surface of the first reduction box 404.

[0029] Embodiment Two

[0030] On the basis of Embodiment One, in order to make up for the problem that it is not convenient to cool the copper wire in Embodiment One.

[0031] As Figures 1 - 4 shown, the air intake module 5 includes mounting seats 501. The number of mounting seats 501 is four, and the mounting seats 501 are fixedly installed on the inner wall of the heating box 2. A guide rod 502 is fixedly connected inside the mounting seat 501. A spring 503 is nested on the outer surface of the guide rod 502, and a sliding seat 504 is nested and slidably connected to the outer surface of the guide rod 502. A rotating shaft 505 is rotatably embedded in the top surface of the heating box 2, and an oval pressing plate 507 is fixedly connected to the lower end of the rotating shaft 505. The oval pressing plate 507 contacts one of the sliding seats 504. An air intake frame 602 is fixedly connected to the lower surface of the sliding seat 504.

A rotating frame 603 is rotatably connected to the outer surface of the air intake frame 602, and a counterweight 604 is fixedly connected to the end of the rotating frame 603.

[0032] In this embodiment, during use, the external nitrogen pipeline is connected to the intake pipe 6. The gas enters the metal hose 601 and the intake frame 602 in sequence through the intake pipe 6, and then is discharged from the air outlet at the position of the rotating frame 603. When the elliptical extrusion disk 507 rotates, it extrudes the sliding seat 504, causing the sliding seat 504 to extrude the spring 503. Thus, the sliding seat 504 can drive the intake frame 602 to slide on the guide rod 502. When sliding, the rotating frame 603 drives the counterweight piece 604 to swing, guiding the gas discharged from the intake frame 602 and making the gas distribution more uniform, improving the effect of nitrogen in preventing the copper wire from being heated and oxidized.

First synchronous pulleys 506 are fixedly connected to the outer surfaces of the second stirring shaft 704 and the rotating shaft 5, and a second synchronous belt 707 is meshed with the outer surface of the first synchronous pulley 506. A heat exchange pipeline 708 is embedded and fixedly connected to the side surface of the water tank 701.

[0034] In this embodiment, the copper wire passes through the heat exchange pipeline 708 on the side surface of the water tank 701 to prevent the heat exchange pipeline 708 from directly contacting the water. The heat exchange pipeline 708 cooperates with the cold water in the water tank 701 for cooling. The external water supply pipeline is connected to the water tank 701. This belongs to the prior art and will not be elaborated here. A second reduction gearbox is fixedly connected to the upper surface of the water tank 701. A second stepping motor is fixedly connected to the upper surface of the second reduction gearbox. The output end of the second reduction gearbox is fixedly connected to the second stirring shaft 704. Therefore, after starting the second stepping motor, the second stirring shaft 704 drives the first stirring shaft 702 to rotate through the second synchronous pulley 705 and the first synchronous belt 706, causing the stirring blades 703 to stir the water in the water tank 701 and making the temperature distribution of the water more uniform. The first synchronous pulley 506 drives the rotating shaft 5 to rotate through the second synchronous belt 707, providing power for the rotation of the elliptical extrusion disk 507.
