Description

Technical Field

[0002] Wire feeding is a very important operation link in the welding process. The wire feeder is a device used for welding. Its working principle is to use the main shaft to drive the gear to rotate. The four wire feeding wheels apply an axial thrust to the welding wire, reduce the forward resistance of the welding wire, make the welding wire more smoothly transported forward, and deliver the welding wire to the designated position, thereby improving the quality of the welding weld and production efficiency.

[0003] According to the Chinese patent application number 202323164539.4, a four-wheel auxiliary wire feeder is disclosed, which includes a shell, an adjusting component is provided on the top of the shell, and the adjusting component includes an internal threaded tube welded to the top of the shell, an adjusting screw is sleeved through the internal threaded tube, and the bottom end of the adjusting screw is located inside the shell and is connected to a layer plate through a bearing, and pressure groove wheels are installed at both ends of the bottom of the adjusting component through a mounting frame, and an air motor is fixed to one side of the shell by bolts. By rotating the adjusting screw, the layer plate is pushed down, so that the pressure groove wheels at both ends of the bottom are moved down, and the welding wire is pressed on the two groove wheels. After the external compressed air passes through the air motor, it drives the large gear to rotate. The rotation of the large gear drives the shaft rod and the groove wheels on its outside to rotate through the small gear, and the rotation of the groove wheels transports the welding wire.

[0004] However, when the four-wheel auxiliary wire feeder adjusts the two pressing groove wheels to press the material, the staff needs to manually turn the adjustment screw to adjust the alignment, which increases the workload of the staff and reduces the practicality of the four-wheel auxiliary wire feeder. For this reason, we propose a wire feeding wheel assembly for the wire feeder. Utility Model Content
