Powder scraping device for roller table

The utility model discloses a powder scraping device for a roller table. The powder scraping device is erected on a rack, and comprises two rails (1) laid along the two sides of the rack, and a driving shaft (2) and a driven shaft (3), which are fixedly arranged at the two ends of the rails, wherein the driving shaft (2) is driven by a motor (4), and forms transmission with the driven shaft (3) through a synchronous belt (5); a powder scraper (6) is fixedly arranged on the synchronous belt (5); pulleys (7) are arranged at the two ends of the powder scraper, are matched with the rails (1), and reciprocally slide along the rails. The powder scraping device is simple and reasonable in structure, and can be applied to the scraping of powder accumulated on a bottom plate of the roller table; the powder scraper is fixedly arranged on the synchronous belt for transmission between the driving shaft and the driven shaft, and intermittently and reciprocally moves along the rails under the support of the rails to realize automatic powder scraping operation; the device can stably and reliably run; the environment of a workshop can be favorably kept clean.
