The screening device in the technical solution of this patent dries the tin powder while screening it.

[0003] When the device in the above patent screens tin powder, centrifugal force is used to separate tin powders of different sizes. However, during screening, part of the tin powder may be stuck inside the sieve holes, which greatly reduces the screening efficiency and effect, and causes waste of tin powder, thereby reducing the practicality of the device.

[0004] For this reason, the present application proposes a tin powder screening device for tin powder production. Utility Model Content

[0005] The tin powder screening equipment for tin powder production proposed in the present application solves the problems raised in the above-mentioned background technology; the tin powder screening equipment for tin powder production can prevent the sieve holes from being blocked by arranging a vibration mechanism, a support plate, a No. 2 motor, a No. 2 rotating rod, an elliptical wheel, a fixed block, a sliding triangular block, a lifting block, an L-shaped rod and a limiting rod. The No. 2 rotating rod and the elliptical wheel are driven to rotate by the No. 2 motor. The rotation of the elliptical wheel causes the sliding triangular block to slide outside the fixed block. The sliding of the sliding triangular block drives the lifting block to move up and down, and finally drives the L-shaped rod to move up and down. The limiting rod is used to limit the L-shaped rod and the lifting block to prevent them from shifting.

[0034] Working principle: When the device is working, the tin powder is poured into the conveying cylinder 21 through the feed port 22, the No. 1 motor 23 is started to drive the No. 1 rotating rod 24 to rotate, and then the No. 1 rotating rod 24 drives the rotating blade 25 to rotate.
