Automatic sand pressing device for glass fiber asphalt shingle

The utility model discloses an automatic sand pressing device for glass fiber asphalt shingles, which comprises support frames, the support frames are symmetrically arranged, and a multi-compression-roller mechanism is arranged between every two adjacent support frames; glass fiber asphalt shingles enter through the conveying compression roller unit, slabstone particles are poured and scattered from the top of the slabstone particle pouring plate, after the slabstone particles on the top of the glass fiber asphalt shingles are evenly brushed flat through the sand brushing roller, the glass fiber asphalt shingles and the slabstone particles are compacted through the compacting unit, and finally the glass fiber asphalt shingles and the slabstone particles are conveyed through the conveying unit. Local accumulation of stone plate particles on the surface of the glass fiber asphalt shingle is avoided, unevenness of the glass fiber asphalt shingle is reduced, and the quality of the glass fiber asphalt shingle is i
