The utility model relates to a ration formula eiderdown opens tiling device, mainly by plucker roller, open the case and the tiling case is formed, plucker roller places perpendicularly and is openingthe incasement, opens case neighbour side for the case that tiles, the two passes through the pipe connection, plucker roller mainly comprises at the epaxial multilayer flabellum of initiative driving shaft and ann, has flabellum, adjacent two -layer flabellum staggered arrangement with ann on the one deck on the driving shaft, the tiling case mainly comprises last box and lower box, goes up under the box bottom surface and be with the one side with box upper base face down, go up box and cabinet bottom surface shape homogeneous phase down with, bottom surface central point is on same straight line, the bottom surface all is regular polygon, goes up bottom surface under the bottom surface is greater than on the box, connect the conveyer pipe on going up box two relative faces, open the bottom of the case and open and have a plurality of through -holes, through -hole and duct connections. The utility model discloses optimize plucker roller, has improved and opened efficiency, optimizethe tiling case, improved procumbent homogeneity, realized opening with procumbent integration, improved production efficiency greatly.
