The first rotating wheel 13 is connected to the output shaft of the first conveying motor 12. When the mandrel falls, When the mandrel reaches the bottom of the silo 11, the first rotating wheel 13 is used to fix and convey the mandrel. When the mandrel at the bottom of the silo 11 is conveyed, the remaining mandrels will fall to the bottom of the silo 11 in turn, and the mandrels are separated and conveyed in a reciprocating manner; the copper tube separation unit 2 is used to complete the separation of the copper tube. The structure of the copper tube separation unit 2 is exactly the same as that of the mandrel separation unit 1.

Due to the design of the arc surface of the Y-shaped silo wall in the core rod separation unit 1 and the copper tube separation unit 2 and the influence of the gravity of the copper tube or the core rod itself, the copper tube and the core rod will roll down to the discharge part of the Y-shaped silo in turn. The control system controls the first conveying motor 12 to rotate, and the first rotating wheel 13 drives the bottom core rod to the right to the bottom copper tube on the right by relying on friction, completing a rod insertion task; then the control system controls the second conveying motor 22 to rotate, and the second rotating wheel 23 drives the finished product that has completed the rod insertion task to continue to be conveyed to the right by relying on friction, and then the third conveying motor 3 rotates to convey the finished product to the groove 41 in the turntable 4. Then the first rotating motor 5 drives the turntable 4 to rotate a certain angle. Due to the influence of gravity, the finished product slides into the receiving funnel 6, and the finished product slides into the "double-helix" sintering furnace 7 through the holes of the receiving funnel 6, completing a heat pipe separation and transmission rod insertion task; then the second rotating motor 73 at the bottom of the "double-helix" sintering furnace 7 rotates a certain angle, so that the next empty hole in the orifice plate 71 of the "double-helix" sintering furnace 7 rotates to the bottom of the receiving funnel 6 according to the designed double-helix trajectory, and then the control system controls the third transmission motor 3 to repeat the above action, and repeats this reciprocating process. After the second rotating motor 73 at the bottom of the "double-helix" sintering furnace 7 completes the designed double-helix track, the finished product can completely fill the sintering furnace hole.
