When welding the steel plates in a factory, workers need to use a fixing plate to fix the three steel plates with screws and nuts, and then weld the right-angle gaps on the non-fixed surfaces of the steel plates. After welding one side, the fixing plate is removed and the other side is welded. After the welding work is completed, workers are required to grind the welds. Such a process is too complicated and inefficient, which greatly increases the workload of workers.

When the roller assembly 4 rotates one circle, the internal steel plate is welded, and the unwelded steel plate is pushed into the roller assembly 4. At the same time, the first baffle assembly 6 and the second baffle assembly 8 are opened, and the end of the roller assembly 4 is no longer closed. The DC motor 1004 rotates, and the transmission Under the action of the assembly 10, the welded steel plate moves toward the discharge port 105. After the welded steel plate completely leaves the roller assembly 4, the first baffle assembly 6 and the second baffle assembly 8 are closed again to seal the end of the roller assembly 4. Under the action of the left transmission support plate 106 and the right transmission support plate 104, the welded steel plate will not fall during the movement toward the discharge port 105. Before the welded steel plate is about to be discharged from the discharge port 105, the grinding gun 901 inside the discharge port 105 will grind the weld of the steel plate, and the steel plate will be received by the worker after extending from the discharge port 105.
