The invention discloses a straight line feeder for a SMD inductance packing machine. The straight line feeder comprises a vibration plate; opening T-shaped grooves are formed in the two sides of the upper surface of the vibration plate; upper projections are arranged on the upper surfaces in the opening T-shaped grooves; a groove is formed in the center of the upper surface of the vibration plate;a spring groove is formed in the bottom surface in the groove; a tension spring is fixedly mounted in the spring groove; the upper surface of the tension spring is fixedly connected with a tension rod; the upper surface of the tension rod is fixedly connected with a tension plate; conveying bases are slidingly connected into the opening T-shaped grooves through T-shaped blocks; the upper surfacesof the T-shaped blocks are slidingly connected to the outer surfaces of the upper projections through lower projections; and the tension plate is slidingly connected to the lower surfaces of the conveying bases. The straight line feeder for the SMD inductance packing machine can greatly improve the inductance packing efficiency through connection between the structure tensioned by the tension spring and the T-shaped slide blocks, and prevents material wastes.
