[0036] The servo motor 210 works to drive the worm 220 connected to the shaft 211 to rotate, and at the same time drives the worm wheel 230 that cooperates with the worm 220 to rotate synchronously;

[0037] Please continue reading Figure 1 , Figure 3 and Figure 4 The translation stirring component 300 is slidably connected to the melt box 100, and moves synchronously with the power component 200 to stir the melt in the melt box 100;

[0038] The translation stirring component 300 includes a threaded screw 310 connected to the outside of the worm gear 230 through a positioning bolt and rotates synchronously with the worm gear 230. A threaded seat 320 is screwed on the threaded screw 310.

[0040] Translation action:

[0041] The threaded screw 310 rotates synchronously with the worm gear 230. Since the threaded seat 320 is threadedly engaged with the threaded screw 310, and the rotation direction of the threaded seat 320 is limited by the guide groove 111 and the guide seat 321, when the threaded screw 310 rotates, the threaded seat 320 drives the mounting frame 330 to translate along the top of the melt box 100, thereby driving the lateral position of the stirring member composed of the stirring blade 342 and the stirring motor 340 to change, thereby increasing the stirring range and improving the melting efficiency of the melt.

[0044] Air supply action:

[0045] During the rotation of the shaft 211 , the linkage gear set consisting of the driving gear 410 and the driven gear 420 is driven to rotate, and then the fan blades 422 are driven to rotate to generate wind force. The wind force acts on the melt box through the connecting pipe 431 to form warm wind to maintain the internal temperature of the melt box 100 .

[0046] Working principle: When the utility model is in use, the servo motor 210 drives the worm 220 to rotate, and drives the worm wheel 230 that cooperates with the worm 220 to rotate synchronously. At the same time, the threaded screw 310 rotates synchronously with the worm wheel 230. Since the threaded seat 320 is threadedly matched with the threaded screw 310, and the rotation direction of the threaded seat 320 is limited by the guide groove 111 and the guide seat 321, when the threaded screw 310 rotates, the threaded seat 320 drives the mounting frame 330 to translate along the top of the melt box 100, and then drives the lateral position of the stirring member composed of the stirring blade 342 and the stirring motor 340 to change, thereby increasing the stirring range and improving the melting efficiency;

[0047] Furthermore, during the rotation of the shaft 211, the linkage gear set consisting of the driving gear 410 and the driven gear 420 is driven to rotate, thereby driving the fan blades 422 to rotate to generate wind force, and the wind force acts on the melt box through the connecting pipe 431 to form warm wind to maintain the internal temperature of the melt box 100.

[0048] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
