[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A mobile MIG / MAG welding machine for steel beam welding includes a welding machine body 1. Retrieval mechanisms 2 are installed on both the left and right sides of the welding machine body 1 for automatic retrieval of the welding wire and ground wire. The retrieval mechanism 2 includes:

[0025] The gathering unit 21 is located on the left and right sides of the MIG welding machine body 1 and is used to place the welding wire or ground wire.

[0026] The take-up and take-down unit 22 is located above the take-up unit 21 and includes a mounting base 222. A motor 223 is fixedly mounted on the outside of the mounting base 222, and a main rotating wheel 224 is fixedly mounted through the output end of the motor 223 through the mounting base 222. A cross slide groove 225 is opened inside the mounting base 222, and a cross slider 226 is slidably mounted inside the cross slide groove 225. An auxiliary rotating wheel 227 is rotatably mounted on the inside of the cross slider 226. The main rotating wheel 224 is driven to rotate by the motor 223 to realize the automatic retraction of the welding wire or ground wire.

[0027] The motor 223, model KV3SF-8521F-WR, is electrically connected to an external power supply and is operated by a human-controlled control panel. The welding wire or ground wire passes through the lower guide ring 2210, between the auxiliary wheel 227 and the main wheel 224, and the upper guide ring 229. Rotating the lead screw 228 drives the cross slider 226 to move towards the main wheel 224. The auxiliary wheel 227 moves synchronously and clamps the welding wire or ground wire through the main wheel 224. Then, the motor 223 runs and drives the main wheel 224 to rotate, so that the welding wire or ground wire is collected into the take-up hopper 212, thereby realizing the automatic recycling of the welding wire or ground wire and reducing the labor intensity of the operator.

[0028] In this embodiment, a lead screw 228 is rotatably mounted inside the cross slide groove 225, and a cross slider 226 is threadedly mounted on the surface of the lead screw 228. The distance between the main rotating wheel 224 and the auxiliary rotating wheel 227 is adjusted by driving the cross slider 226 to move through the lead screw 228.

[0029] The distance between the main rotating wheel 224 and the auxiliary rotating wheel 227 is adjusted by rotating the lead screw 228 to drive the cross slider 226 to move, thereby adjusting the clamping force of the main rotating wheel 224 and the auxiliary rotating wheel 227 on the welding wire or ground wire and avoiding slippage when retrieving the welding wire or ground wire.

[0030] In this embodiment, a fixing bracket 221 is fixedly installed on the outer side of the mounting base 222, an upper guide ring 229 is fixedly installed on the top of the mounting base 222, and a lower guide ring 2210 is fixedly installed on the bottom of the mounting base 222 to guide the welding line or ground line.

[0031] The welding wire or ground wire passes through the interior of the lower guide ring 2210, between the auxiliary wheel 227 and the main wheel 224, and inside the upper guide ring 229, thereby guiding the welding wire or ground wire.

[0032] In this embodiment, the gathering unit 21 includes a base 211 fixedly installed on the side of the MIG welding machine body 1. A take-up drum 212 is fixedly installed on the top of the base 211. A winding drum 213 is fixedly installed inside the take-up drum 212. A top cover 214 is fixedly installed on the top of the winding drum 213. A mounting base 222 is fixedly installed above the top cover 214 through a fixing bracket 221. The space between the winding drum 213 and the take-up drum 212 is used for winding welding wire or ground wire. A motor 215 is fixedly installed at the bottom of the top cover 214. A rotating rod 216 is fixedly installed through the top cover 214. A ring 217 is fixedly installed at the end of the rotating rod 216.

[0033] Motor 215 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and its opening and closing operation is achieved through a human-operated control panel. The welding wire or ground wire passes through the take-up cassette 212 and enters the space between the take-up cassette 212 and the drum 213, and passes through the inside of the ring 217. When the welding wire or ground wire is taken into the space between the take-up cassette 212 and the drum 213 through the take-up and untake-down unit 22, the motor 215 drives the rotating rod 216 and the ring 217 to rotate, and at the same time drives the welding wire or ground wire to wind around in the space between the take-up cassette 212 and the drum 213, thereby realizing the orderly take-up of the welding wire or ground wire into the space between the take-up cassette 212 and the drum 213.

[0034] In this embodiment, heat dissipation grooves 218 are provided on both the front and rear sides of the drum 213 to dissipate the heat generated by the operation of the motor 215 inside the drum 213.

[0035] The heat dissipation grooves 218 opened on both the front and rear sides of the drum 213 are used to dissipate the heat generated by the operation of the motor 215 inside the drum 213.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, the welding wire or ground wire first passes through the take-up hopper 212 into the space between the take-up hopper 212 and the drum 213, and passes through the inside of the ring 217. At the same time, it passes through the inside of the lower guide ring 2210, between the auxiliary wheel 227 and the main wheel 224, and inside the upper guide ring 229. At this time, the screw 228 is rotated to drive the cross slider 226 to move towards the main wheel 224. The auxiliary wheel 227 moves synchronously and clamps the welding wire or ground wire through the main wheel 224. Then, the motor 223 runs and drives the main wheel 224 to rotate, so that the welding wire or ground wire is drawn into the inside of the take-up hopper 212. At the same time, the motor 215 runs and drives the rotating rod 216 and the ring 217 to rotate, so that the welding wire or ground wire is wound around the space between the take-up hopper 212 and the drum 213, so that the welding wire or ground wire is orderly drawn into the space between the take-up hopper 212 and the drum 213, completing the automatic retrieval of the welding wire or ground wire.
