[0032] Specifically, after melting inside the furnace body 3, the cored wire will enter the cooling tube 2 through the discharge pipe 7. In order to cool the cored wire, a circulating pump 11 is used to extract the coolant in the water tank 5 and input it into the threaded tube 8. The threaded tube 8 surrounds the outer wall of the discharge pipe 7, thereby cooling the cored wire inside the discharge pipe 7. The coolant is discharged back to the water tank 5 through the threaded tube 8 to form a circulation system so that the coolant can be repeatedly used to cool the cored wire. After cooling, the fixed winding drum 6 is fixed by the fixed roller 13, and the fixed roller 13 is driven to rotate by the motor 12, so that the winding drum 6 can wind up the cooled cored wire.

[0033] Reference Figure 1 and Figure 2 The outer wall of the cooling pipe 2 is provided with a fixing assembly, the fixing assembly includes a flange 9 and a flange 2 10, the inner wall of the flange 9 is fixedly connected to one side of the outer wall of the cooling pipe 2, the inner wall of the flange 2 10 is fixedly connected to one side of the outer wall of the furnace body 3, one side of the outer wall of the flange 9 is fixedly connected to one side of the outer wall of the flange 2 10, and the top of the furnace body 3 is fixedly connected with a feed valve 4;

[0037] Working principle: the cored wire after melting inside the furnace body 3 will enter the discharge pipe 7 inside the cooling pipe 2, and then the coolant inside the water tank 5 will be extracted by the circulating pump 11, and input into the threaded pipe 8, and then guided back to the water tank 5 by the threaded pipe 8 for recycling, and the threaded pipe 8 is wound around the outer wall of the discharge pipe 7, so as to cool the cored wire inside the discharge pipe 7, and then the fixed roller 13 is fixed to the winding drum 6, and then the fixed roller 13 is driven by the motor 12 to rotate, so that the winding drum 6 can wind up the cooled cored wire, and when the winding drum 6 is fixed, the forward and reverse screw rods 15 can be driven by the motor 2 14 to rotate, and the forward and reverse screw rods 15 can drive the movable blocks 17 on both sides to move synchronously toward the center, and then the movable block 17 on one side will push the transmission rod 1 19, and the movable block 17 on the other side will push the transmission rod 2 20, so that the two cooperate to support the top of the support plate 18, and the support plate 18 can fix the winding drum 6, which is convenient for fixing and replacing the winding drum 6.
