Screening vibration tray for skeleton-type rubber cores

The invention discloses a screening vibration tray for skeleton-type rubber cores, wherein the screening vibration tray is applied to a feeding screening machine. The screening vibration tray comprises a tray body (5) and a spiral track (4), the spiral track (4) is provided with a screening notch (3), and a toothed screening bar (2) is arranged at the position, above the screening notch (3), of the tray body (5). The lower side of the toothed screening bar (2) is provided with a plurality of screening pins (7) connected with the toothed screening bar (2). The screening vibration tray can be used for rapidly, simply and uniformly discharging and feeding the skeleton-type rubber cores in time in the consistent direction in the sliding process, feeding is natural, smooth and timely, and the original problems of nonuniform distribution, frequent blockage and the like are solved. Thus, feeding efficiency is improved, the requirements of the next procedure are completely met, and the requirements of high-end custom
