Automatic feeding mechanism of feed cylinder

The invention discloses an automatic feeding mechanism of a feed cylinder. The mechanism comprises an accumulating frame (2), a transport channel (6) and a centering device (10); the centering device is arranged on the transport channel (6) and comprises two ejector blocks (12) which are symmetrically arranged along the central axis of the transport channel (6), when a workpiece reaches a discharging portion (8), the ejector blocks (12) can at least complete clamping motion of the workpiece one time, and the workpiece is located over the central axis of the transport channel (6). Automatic feeding of the feed cylinder and precise positioning after feeding can be achieved, and problems in the prior art are solved; and the production efficiency is improved, and automation production is achieved. 本发明公开了种料筒自动送料机构，包括累料架(2)、运输通道(6)，以及定心装置(10)，所述定心装置设置在所述运输通道(6)上，其包括两块沿着所述运输通道(6)的中心轴线对称设置的顶块(12)，所述顶块(12)在有工件到达出料部(8)时，能够至少完成次对该工件的夹紧运动，使该工件位于运输通道(6)中心轴线的正上方。本发明能够实现料筒的自动送料以及送料之后的精确定位，解决了现有技术中遇到的问题。提高了生产效率，实现了自动化生产。
