Automatic feeder for label laser marking
2014
The invention discloses an automatic feeder for label laser marking. The mode that synchronous belts, shafts and friction wheels are matched is adopted. A first motor output shaft drives a first synchronous belt by a first synchronous belt pulley to rotate, drives a second synchronous belt pulley, a third synchronous belt pulley and a fourth synchronous belt pulley to rotate, and drives a first shaft, a second shaft and a third shaft to rotate; the other ends of the first shaft, the second shaft and the third shaft are provided with a first friction wheel, a second friction wheel and a third friction wheel respectively; the first friction wheel, the second friction wheel, the third friction wheel, the first shaft, the second shaft and the third shaft rotate synchronously; the upper horizontal tangent planes of the first friction wheel and the second friction wheel and the lower horizontal tangent plane of the third friction wheel are located on the same plane, and the first friction wheel, the second friction wheel and the third friction wheel rotate in the same direction; labels inside a feed hopper are directly pressed on the first friction wheel and the second friction wheel, the label at the bottommost face moves leftwards under the action of rotation of the first friction wheel and the second friction wheel and is conveyed to the third friction wheel; only one label passes under the action of reverse rotation of the third friction wheel. The automatic feeder for label laser marking can accurately control the transmission of the labels and know the errors of the system in the operation process in real time.
