The technical purpose of the invention is realized by the following technical scheme: the utility model provides a clamping piece material feeding unit, including the row material seat, be provided with horizontal row's silo in arranging the material seat, still include the drive arrangement that the drive clamping piece removed along row's silo, arrange the material seat outside and be provided with the shelves pole one and the shelves pole two that penetrate row's silo, still include the ejector pad, the ejector pad is installed on pusher, the ejector pad can reciprocate and along row's silo direction horizontal pushing under pusher's effect, row's silo front end is provided with the elastic positioning device who blocks the clamping piece, row's silo between elastic positioning device and the shelves pole one is the propelling movement section.
Through above-mentioned technical scheme, the row material tank rear end can link to each other with loading attachment such as vibration dish and make the clamping piece send into one by one in the row material tank to transversely arrange in row material tank. And then the clamping piece moves towards the front end of the discharge groove under the action of the driving device. The first blocking rod and the second blocking rod extend into the discharge groove, and can extend into or withdraw from the discharge groove under the action of the power device. And only one clamping piece can be placed in the space between the first blocking rod and the second blocking rod. The first blocking rod and the second blocking rod are matched to separate the clamping pieces, so that the clamping pieces are conveyed to the front end of the discharge groove one by one. Because the whole length of clamping piece is less to the laminating is comparatively inseparable between the adjacent clamping piece, does not set up two shelves poles and can't separate the clamping piece one by one accurately, if can't separate the clamping piece one by one the ejector pad can't accurately stretch into the clamping piece rear, thereby promotes the clamping piece and removes to row silo front end. The elastic positioning device can position the single clamping piece moved to the front end of the discharge groove to enable the single clamping piece to be positioned in front of the initial position of the push block, and then the push block moves downwards to push the clamping piece to overcome the blocking of the elastic positioning device and send the clamping piece into the clamping seat.
