Material spreading device and additive manufacturing equipment using same

A material spreading device comprises a material spreading bin, the material spreading bin is provided with a raw material inlet and a raw material outlet, a vibrating screen is further arranged at the raw material outlet, and the vibrating screen is connected to the raw material outlet in a bridging mode so that raw materials can fall down after passing through the vibrating screen. Therefore, the raw materials have good fluidity and evacuation performance. The vibrating screen is arranged at the raw material outlet of the spreading bin, so that falling raw materials can have better fluidity and dispersion under the action of the vibrating screen, and the surface quality of a spreading surface is guaranteed. 一种铺料装置，所述铺料装置包括铺料仓，所述铺料仓设有原材料入口和原材料出口，在所述原材料出口处还设有振动筛，所述振动筛跨接在所述原材料出口处，可以使原材料通过所述振动筛后下落，使得所述原材料具有良好的流动性和疏散性。通过在铺料仓的原材料出口处设置所述振动筛，使得下落的原材料在振动筛的作用下能够具有更好的流动性和疏散性，从而保证了铺料面的表面质量。
