The working principle of the invention is as follows: when in use, firstly, the telescopic rod 401 is adjusted, the support rod 402 is used for adjusting the inclination angle and the guiding direction of the first guide pipe 403, one end of the welding wire on the unreeling roller 101 penetrates into the second guide pipe 404 through the bell mouth 406 and is clamped by the traction roller 405, then the welding wire is led out through one end of the first guide pipe 403 and enters the straightening and tensioning mechanism 2, when the welding wire is supported and adjusted by the support adjusting mechanism 4, because the unreeling roller 101 has a certain width, and the position of the welding wire entering the straightening and tensioning mechanism 2 is certain, at the moment, through the swinging of the second guide pipe 404, the problem that the swinging amplitude of the welding wire is too large due to the width of the unreeling roller 101 can be reduced, the swinging amplitude of the welding wire in the unreeling process can be reduced, the situation that the welding wire is broken can be avoided, and the direction of the first guide pipe 403 can be adjusted according to the support rod 402, the self-adaptive adjustment can be carried out according to actual needs;

when the welding wire enters the straightening and tensioning mechanism 2, the welding wire firstly passes through the first limiting wheel 2021 and the second limiting wheel 2022, then is wound back and forth between the two winding and tensioning wheels 203, and finally enters the straightening mechanism 207 through the guide wheel 206, under the action of the straightening mechanism 207, the welding wire is straightened, and then enters the winding mechanism 3 through the guide wheel 301, when the welding wire is loosened inside the straightening and tensioning mechanism 2, the position of one winding and tensioning wheel 203 is adjusted through the adjusting cylinder 205, so that the welding wire is tensioned, and an adjusting signal is transmitted to the unwinding mechanism 1, so that the unwinding speed of the unwinding mechanism 1 is slowed down;

before entering the winding mechanism 3, firstly, the clamping mechanism 302 is needed to clamp the welding wire, one end of the welding wire is clamped into a Z shape, then the manipulator is used to clamp one end of the welding wire, one end of the welding wire is sent to the position of the insertion groove 3061 of the welding wire disc 306, one end of the welding wire is inserted into the insertion groove 3061, then the welding wire is clamped in the fixing groove 3062, at the moment, the driving motor is used to drive the rotating column 304 to rotate, so that the rotating column 304 drives the welding wire disc 306 to rotate, the welding wire is wound by the welding wire disc 306, after the welding wire on the welding wire disc 306 is wound, the clamping mechanism 302 is used again to clamp the welding wire, then the cutting-off 303 is used to cut off the welding wire, at the moment, the manipulator is used again to transfer the other end of the welding wire to the position of the welding wire disc 306, the other end of the welding wire is inserted into the bending groove 3063, at the moment, the welding wire passing through the bending groove 3063 is clamped by the bending clamp 3010, the welding wire penetrating into the bending groove 3063 can be bent by utilizing the rotation of the rotary cylinder 309, so that the welding wire is fixed on the welding wire disc 306;

after the wire reel 306 is completely wound with a welding wire, the whole rotary column 304 is communicated with the wire reel 306 and is transferred backwards together by using the telescopic cylinder 3081, then the fixing cylinder 3051 is used for extending, the driving seat 3052 is driven to drive one end of the L-shaped fixed rod 3054, the L-shaped fixed rod 3054 is enabled to release the fixation of the wire reel 306, the whole fixing device 305 is returned by using the returning cylinder 307, at the moment, the bottom end of the wire reel 306 extends out of the cylinder to support the wire reel 306, then the position of the rotary column 304 is adjusted by using the fine adjustment cylinder 3082, the rotary column 304 is separated from the wire reel 306, and the fine adjustment cylinder 3082 is used for adjustment, so that the stroke of the cylinder is shorter, and the whole design structure is more compact;

then the extended cylinder retracts, and the wire reel 306 wound with the welding wire is sent out through the channel;

then install new wire reel 306 again, reuse fixing device 305 to fix it, reuse telescopic cylinder 3081 to send wire reel 306 back to the normal position, reuse manipulator to insert the one end of the welding wire that fixture 302 gripped in inserting groove 3061, repeat the above-mentioned operation, the interface realizes automatic twines the welding wire, has practiced thrift the manpower, and, degree of automation is higher.
