Abstract

The utility model discloses an automatic adjusting edge-scraping mechanism which comprises a rack, an edge-scraping cutter and a bi-directional shifting seat arranged on the rack and controlling the edge-scraping cutter to feed. A workpiece feed mechanism is arranged on one side of the rack, an adjusting device controlling a workpiece to move transversely on the workpiece feed mechanism is arranged above the edge-scrapping cutter, and a synchronous connection piece is arranged between the adjusting device and the edge-scraping cutter. During the working process of the automatic adjusting edge-scraping mechanism, when the thickness of an edgeband changes, the adjusting device works and changes the position of the workpiece on the feed mechanism to guarantee the accordance of the thickness of a scraping edge and the thickness of the edgeband. Meanwhile, the adjusting device drives the edge-scraping cutter through the synchronous connection piece and changes the contacting position of the blade of the edge-scrapping cutter and the workpiece, the arc center section of the blade of the edge-scraping cutter is made to be close to the edge-scrapping surface of the workpiece, and therefore the effects that radian is larger and evenness is better are achieved. According to the automatic adjusting edge-scraping mechanism, the synchronous connection piece takes the place of a dual-motor structure, and therefore, processing cost is effectively saved, and the automatic adjusting edge-scraping mechanism is suitable for the field of wood-working machines.
