<p>A circulating type conveying mechanism (10) comprises a frame (20), on which a chain unit (30) is mounted. The chain unit having two parallel chains can circularly rotate along the horizontal direction and the vertical direction, wherein one horizontal end of the chain unit is the first end (38a), and the other horizontal end of the chain unit is the second end (38b). A bracket (40) is connects with the two chains (32, 34) of the chain unit, one side of which is a bearing surface. A first guiding component (50) assembled on the frame corresponds to the first end (38a) of the chain unit (30), and a second guiding component (60) assembled on the frame (20) corresponds to the second end (38b) of the chain unit (30). The bracket (40) can circularly rotate with the chain unit (30) along the horizontal direction and the vertical direction, and the bracket can be limited by the first guiding component and the second guiding component when being switched between the horizontal direction and the vertical direction, which keeps the bearing surface of the bracket upward. Consequently, it needs only one operator to place the workpiece to be processed and take out the processed workpiece.</p> |
