[0017] The drive mechanism includes a servo motor 5 and a servo motor 10. Both servo motor 5 and servo motor 10 are fixedly mounted on the frame 4. The output end of servo motor 5 is fixedly connected to a rotating wheel 1. A belt 6 is provided between the rotating wheel 1 and the wheel 305. The rotating wheel 1 and the wheel 305 are connected by the belt 6. A connecting frame 7 is fixedly connected to the frame 4. A fixing plate is fixedly connected to the outer wall of the connecting frame 7. A shaft is fixedly connected to the inner wall of the fixing plate. A drive wheel 8 is fixedly connected to the rear end of the shaft. A rotating disk 9 is fixedly connected to the front end of the shaft. The output end of the servo motor 10 is fixedly connected to the rotating wheel 2. A belt 2 11 is provided between the rotating disk 9 and the rotating wheel 2. The rotating disk 9 and the rotating wheel 2 are connected by the belt 2 11. The adjustment mechanism 2 includes an adjustment frame 201, with a fixed block 202 fixedly connected to the inner wall of the adjustment frame 201. A rotating rod is rotatably connected to the inner wall of the fixed block 202. A pre-treatment roller 203 is fixedly connected to the front end of the rotating rod, and a driven wheel 204 is fixedly connected to the rear end of the rotating rod. During the pre-treatment process, the servo motor 10 is started, and the belt 11 drives the rotating disk 9 and the drive wheel 8 coaxial with it to rotate. The drive wheel 8 drives the driven wheels 204 on the two adjustment mechanisms 2 to rotate through the belt 12. The driven wheels 204 drive the pre-treatment roller 203 to rotate through the rotating rod. Under the action of the elastic clamping mechanism, the rotating pre-treatment roller 203 and the pre-treatment roller 209 work together to perform preliminary straightening and cleaning on the welding wire before it enters the fine drawing die 303, removing larger dirt or bends, ensuring that the welding wire enters the fine drawing die 303 in a straight and clean state, protecting the fine drawing die 303 and optimizing the fine drawing effect.

[0018] An adjusting screw 205 is threadedly connected to the inner wall of the adjusting frame 201. A movable block 206 is rotatably connected to the lower end of the adjusting screw 205.

Dynamic connection; depending on the initial diameter of the welding wire and the required specifications after fine drawing, the gap between the pretreatment roller 209 and the pretreatment roller 1 203 can be adjusted by rotating the adjusting screws 205 on the two adjusting mechanisms 2. Rotating the adjusting screws 205 will drive the movable block 206 to move up and down along the inner wall of the adjusting frame 201, thereby changing the position of the pretreatment roller 209. The design of the compression spring 207 and the sliding block 208 constitutes an elastic clamping structure, which can provide a stable clamping force with a certain buffering effect for the welding wire, ensuring that the welding wire is effectively straightened and guided, and avoiding the possible flattening of the welding wire or leakage of flux due to rigid clamping.

[0019] In this implementation scheme, the operator inserts the flux-cored welding wire to be finely drawn into the fine drawing mechanism 3 between the pretreatment roller 1 203 and the pretreatment roller 209 of the left adjustment mechanism 2. The flux-cored welding wire passes through the through hole 306 of the rotating shaft 302 in the fine drawing mechanism 3, the fine drawing die 303, the left rotating shaft 302 and its through hole 306, and finally exits between the pretreatment roller 1 203 and the pretreatment roller 209 of the right adjustment mechanism 2, and is guided to the subsequent winding device. Before the equipment is started, according to the initial diameter of the welding wire and the required specifications after fine drawing, the gap between the pretreatment roller 209 and the pretreatment roller 1 203 can be adjusted by rotating the adjusting screws 205 on the two adjustment mechanisms 2. Rotating the adjusting screws 205 will drive the movable block 206 to move up and down along the inner wall of the adjustment frame 201, thereby changing the position of the pretreatment roller 209. This is achieved by compressing the spring 207 and the sliding... The design of the moving block 208 constitutes an elastic clamping structure, which can provide a stable clamping force with a certain buffering effect for the welding wire. This ensures that the welding wire is effectively straightened and guided, while avoiding the flattening of the welding wire or leakage of flux due to rigid clamping. Then, the servo motor 5 is started, which drives the rotating wheel 1 and the wheel disk 305 to rotate synchronously through the belt 6. The wheel disk 305 is fixed on the right rotating shaft 302, thereby driving the entire precision drawing die 303 to rotate around the rotating shaft 302 as the axis. When the welding wire passes through the precision drawing die 303, the welding wire holes on several precision drawing blocks 304 inside it perform a rotating scraping and rolling on the outer surface of the welding wire, achieving high-precision sizing, compaction and surface finishing. This effectively removes the oxide layer and minor defects on the surface of the welding wire, and makes the diameter of the welding wire more uniform. At the same time, it further compacts the flux core and improves the welding quality of the welding wire.

[0020] Working principle: Before operation, based on the initial diameter of the welding wire and the required specifications after fine drawing, the gap between the pretreatment roller 209 and the pretreatment roller 1 203 can be adjusted by rotating the adjusting screws 205 on the two adjusting mechanisms 2. Rotating the adjusting screws 205 will cause the movable block 206 to move up and down along the inner wall of the adjusting frame 201, thereby changing the position of the pretreatment roller 209. The design of the compression spring 207 and the sliding block 208 constitutes an elastic clamping structure, which can provide a stable clamping force with a certain buffering effect for the welding wire, ensuring that the welding wire is effectively straightened and guided, while avoiding the rigidity of the wire. The clamping mechanism may cause the welding wire to flatten or the flux to leak. During operation, the servo motor 5 is started, and the belt 6 drives the rotating wheel 1 and the wheel disk 305 to rotate synchronously. This drives the entire precision drawing die 303 to rotate around the rotating shaft 302. When the welding wire passes through the precision drawing die 303, the welding wire holes on several precision drawing blocks 304 inside the die perform a rotating scraping and rolling motion on the outer surface of the welding wire. This achieves high-precision sizing, compaction, and surface finishing, effectively removing the oxide layer and minor defects on the surface of the welding wire, making the diameter of the welding wire more uniform, and further compacting the flux core to improve the welding quality of the welding wire.
