[0019] By setting up two upper and lower conveying mechanisms 2, the material is fed alternately to the thread rolling machine 1; when the pressure wheel 23 is at the top dead center, the distance from the V-groove wheel 22 is the farthest, which can facilitate the placement of the pull rod 5 into the V-groove wheel 22, and when the V-groove wheels 22 of the two conveying mechanisms 2 are both placed with the pull rod 5 to be processed, the upper conveying mechanism 2 is at the processing height, and the material is fed first, and the first driving motor 21 of the upper conveying mechanism 2 drives each V-groove wheel 22 to rotate synchronously, so that the V-groove wheel 22 conveys the pull rod 5 to the thread rolling machine 1, and a photoelectric proximity switch 11 is provided just above the gap between the two rolling wheels of the thread rolling machine 1, which can detect the end position of the pull rod 5, and when the photoelectric proximity switch 11 detects the end of the pull rod 5, the first driving motor 21 The machine 21 stops working, at which time the drawing rod 5 moves to the thread processing position, and then the pressure wheel 23 descends, approaches the top of the drawing rod 5 or contacts the top of the drawing rod 5, thereby limiting the upward movement of the drawing rod 5 on the V-groove wheel 22; then the thread rolling machine 1 works, and the two thread rolling wheels move closer to each other to perform thread processing on the drawing rod 5; after the thread processing is completed, the two thread rolling wheels of the thread rolling machine 1 move away from each other, and the lifting mechanism 3 drives the lifting frame 4 to rise, so that the lower conveying mechanism 2 moves to the processing height for feeding; at the same time, the first drive motor 21 of the upper conveying mechanism 2 rotates in the opposite direction, driving the V-groove wheel 22 to rotate in the opposite direction, thereby driving the processed drawing rod 5 away from the thread rolling machine 1, and unloading the drawing rod 5.

[0020] In a preferred embodiment, in order to facilitate the lifting of the lifting frame 4, please refer to Figure 1 and Figure 3The lifting mechanism 3 includes a frame 31, a linear actuator 32, a guide sleeve 33 and a guide rod 34.

The wheel axle 24 corresponds to the V-groove wheel 22 one by one. The wheel axle 24 is rotatably mounted on the lifting frame 4. The V-groove wheel 22 is fixedly mounted on the wheel axle 24. Adjacent wheel axles 24 are connected by the chain transmission assembly 25. The first drive motor 21 is connected to one of the wheel axles 24 through a coupling. The first drive motor 21 drives the wheel axle 24 to rotate, and then drives the remaining wheel axles 24 to rotate through the chain transmission assembly 25, and then drives the V-groove wheel to rotate.
