The motor drive gear 15 and the main shaft gear 14 cooperate to achieve transmission. A schematic diagram of its structure is shown below. Figure 2 .
[0031] Two wire-twisting wheels 5 are also provided on the main shaft 6. Each wire-twisting wheel is fixed with multiple spool supports, and each spool support is equipped with a corresponding wire-feeding spool 13. The wire-feeding spool 13 can also be set on the first fixed bracket 2 and is inserted through the round hole of the sleeve 3 into the smooth hollow round rod of the main shaft 6 for wire feeding.

[0035] Installation method of miniaturized dissimilar metal multi-wire stranding device: First, fix the first fixed bracket above the working environment. Then, pass the small stranding end adjustable speed motor shaft through the pre-drilled hole in the first fixed bracket and fix it. A motor drive gear is installed on the small stranding end adjustable speed motor shaft and fixed with positioning screws. Next, fix the first bearing and one end of the main shaft to the first fixed bracket by embedding. Then, at the corresponding position of the motor drive gear, fit the main shaft gear onto the main shaft. Next, sequentially fit the two rotating wheels into the main shaft and continue to fix them with positioning screws. Then, combine the auxiliary stranding device with the second fixed bracket and the second bearing by embedding, connect and fix it to the other end of the main shaft. Finally, install and fix the wire feeding spools in their respective positions, including but not limited to the spool supports corresponding to the first fixed bracket, the first stranding wheel, and the second stranding wheel. The wire feeding end installation is now complete. Fix the take-up end base to one end near the auxiliary stranding device. After fixing the take-up end motor mounting bracket, the small take-up end adjustable speed motor, and the take-up wheel in sequence, the entire device is assembled. After placing the assembled miniaturized dissimilar metal multi-wire stranding device into the working environment, add welding wire, and it is ready to start working.
[0036] Working state of the miniaturized dissimilar metal multi-wire stranding device: This miniaturized dissimilar metal multi-wire stranding device is equipped with multiple wire feeding spools (fixed to the spool support of the stranding wheel by screws in the pre-drilled holes), which can adjust the type and quantity of strands required according to the needs, so as to achieve the diversity of finished products.
[0037] The specific operation process is as follows: This embodiment takes the twisting of four types of welding wire as an example. One type of welding wire is selected as the main wire, and the other three are auxiliary wires. The main wire is wound around the wire feeding spool on the first fixed bracket (or a wire feeding spool with the main wire wound on it is directly selected). It passes through the round hole in the middle of the sleeve into the main shaft and exits from the second fixed bracket into the merging hole of the first wire twisting rod of the auxiliary wire twister. The other three auxiliary wires are wound evenly on the wire feeding spool of the first wire twisting wheel near the first fixed bracket (the included angle between each pair of wire feeding spools is 120°). The auxiliary wires pass through the twisted wire in the same direction (clockwise or counterclockwise). The hollowed-out portion near the outer ring of the rotating wheel extends towards the second twisting wheel, which is closer to the second fixed bracket. It then passes through three corresponding holes in its inner ring (each pair with an included angle of 120°) and moves towards the auxiliary twisting device on the second fixed bracket. After passing through the holes on the disc of the auxiliary twisting device, it merges with the main wire at the merging hole. Driven by a small adjustable-speed motor at the twisting end, it drives the rotation of the main shaft and the two rotating wheels and auxiliary twisting device fixed thereon via gear transmission. This causes the main wire and auxiliary wire to twist together at the merging hole. Finally, the twisted product is collected by the take-up wheel, driven by a small adjustable-speed motor at the take-up end. Similarly, by removing the main wire, a twisting method can be achieved for three types of welding wire without a main wire.
[0038] Taking the stranding of seven types of welding wire as an example, one type of welding wire is selected as the main wire, and the other six are used as auxiliary wires. The main wire is wound around the wire feed spool on the first fixed bracket, passes through the round hole in the middle of the sleeve, enters the main shaft, and exits from the second fixed bracket into the merging hole of the first stranding rod of the auxiliary wire stranding device. Three of the other six auxiliary wires are wound around the wire feed spool of the first stranding wheel near the first fixed bracket (the included angle between each pair of wire feed spools is 120°). The auxiliary wires pass through the hollowed-out part near the outer ring of the stranding wheel in the same direction (clockwise or counterclockwise), extend towards the second stranding wheel near the second fixed bracket, and then pass through the corresponding three holes in its inner ring (the included angle between each pair is 120°) towards the auxiliary wire stranding device on the second fixed bracket. After passing through the holes on the disc of the auxiliary wire stranding device, they enter the merging hole of the first stranding rod of the auxiliary wire stranding device. Additionally... Three types of auxiliary filaments are wound onto the feed spools of the second twisting wheel near the second support end (the included angle between each pair of feed spools is 120°). The position of the feed spools is offset from the spools on the first twisting wheel (the included angle between each pair of the six feed spools is 60°). The auxiliary filaments pass through the hollow part near the outer ring of the second twisting wheel in the same direction as the auxiliary filaments on the first twisting wheel, and move towards the auxiliary twisting device on the second fixed support. After passing through the holes on the disc of the auxiliary twisting device, they merge with the main filament and the other three auxiliary filaments at the merging hole. Driven by the small adjustable speed motor at the twisting end, the main shaft and the two wheels and auxiliary twisting device fixed on it are rotated through gear transmission, so that the main filament and auxiliary filaments are twisted at the merging hole. Finally, the twisted product is collected by the take-up wheel driven by the small adjustable speed motor at the take-up end.
[0039] Taking the stranding of thirteen welding wires as an example, one type of welding wire is selected as the main wire, and the remaining twelve types are used as auxiliary wires. The main wire is wound around the wire feed spool on the first fixed support, passes through the round hole in the middle of the sleeve to enter the main shaft, and exits from the second fixed support to enter the merging hole of the first stranding rod of the auxiliary wire stranding device. Six of the other twelve auxiliary wires are wound around the wire feed spool of the first stranding wheel near the first fixed support (each pair of feed spools has a 60° angle). The auxiliary wires pass through the hollowed-out part of the outer ring of the stranding wheel in the same direction (clockwise or counterclockwise), extending towards the second stranding wheel near the second fixed support. They then pass through the corresponding six holes in the inner ring (each pair has a 60° angle) towards the auxiliary wire stranding device on the second fixed support, and after passing through the holes on the disc of the auxiliary wire stranding device, enter the merging hole of the first stranding rod of the auxiliary wire stranding device. The six auxiliary filaments are wound onto the feed spools of the second twisting wheel near the second support (each pair of feed spools is at a 60° angle). The position of the feed spools is offset from that of the spools on the first twisting wheel (each pair of the twelve feed spools is at a 30° angle). The auxiliary filaments pass through the hollowed-out part near the outer ring of the second twisting wheel in the same direction as the auxiliary filaments on the first twisting wheel, and move towards the auxiliary twisting device on the second fixed support. After passing through the holes on the disc of the auxiliary twisting device, they merge with the main filament and the other six auxiliary filaments at the merging hole. Driven by the small adjustable speed motor at the twisting end, the main shaft and the two wheels and auxiliary twisting device fixed on it are rotated through gear transmission, so that the main filament and auxiliary filaments are twisted at the merging hole. Finally, the twisted product is collected by the take-up wheel driven by the small adjustable speed motor at the take-up end.
