Portal frame type multi-station numerical control carving machine

The utility model discloses a portal frame type multi-station numerical control engraving machine, which relates to the field of engraving machines and comprises a base, a mounting table, a movable groove, a portal frame, a traveling mechanism, a transverse adjusting mechanism and a fixing frame, and a cleaning mechanism is arranged on the outer side of the fixing frame. According to the engraving machine, the sweeping mechanism is arranged, and the sucking pump is started, so that chippings generated in the engraving process are sucked by suction force generated by the sucking pump, enter the collecting pipe after being gathered through the suction nozzle, and then enter the collecting box; the ventilation plate blocks the chippings, so that the chippings are prevented from entering the air extracting pump through the connecting pipe, and the air extracting pump is prevented from being damaged; and after the carving work is completed, the collecting box is taken down from the outer wall of the fixing frame,
