A second motor 16 is fixedly connected to the outside of the limit frame 3, and the output shaft of the second motor 16 is fixedly connected to a one-way threaded rod 17 connected to the internal thread of the scraper 5.
[0029] In this embodiment, the second motor 16 is started to rotate the one-way threaded rod 17, which then drives the scraper 5 to slide inside the limit frame 3, thereby scraping the welding slag off the processing table 1 through the strip hole 4 in time.
