The material storage structure 310 comprises a material storage barrel 311, a material storage rack 312, a material storage baffle 313 and a material blocking driving device 314, wherein the material storage barrel 311 is fixedly connected with the material storage rack 312, the material blocking driving device 314 is fixedly connected with the material storage rack 312 and drives the material storage baffle 313 to do linear reciprocating motion, and the material storage baffle 313 is positioned at an outlet of the material storage barrel 311. The storage barrel 311 is fixed on the storage frame 312 and is positioned on the motion track of the intermediate separation barrel 110. When the weight of the material reaches a predetermined weight, the material slides into the storage cylinder 311 through the intermediate air separation cylinder 110. And since the outlet of the storage barrel 311 is blocked by the material-storing shutter 313, the material is first stored in the storage barrel 311. And then the intermediate separation charging barrel 110 swings to continuously distribute the materials to other storage charging barrels 311, and after all the storage charging barrels 311 store the materials, the material blocking driving device 314 drives the material storage baffle 313 to move, so that the materials fall into the material distribution structure 320 under the action of gravity.

The feeding cavity 410 is used for conveying divided materials, and can be matched with the multi-stage time-sharing blanking structure 3 to avoid the occurrence of the condition of non-connection during material division, so that the production efficiency is improved.

The working principle of the invention is as follows: first, the weight of the material is preset to 500g, and the material will slide into the hollow material-separating cylinder 110 after weighing to reach the set range. Meanwhile, the swing driving device 120 is activated to drive the intermediate air separation barrel 110 to swing, and the material is output to the storage barrel 311. Since the material trap 313 blocks the outlet of the storage cylinder 311, the material is temporarily stored in the storage cylinder 311. Subsequently, 500g of material is reweighed and output to additional storage cylinders 311 until all storage cylinders 311 have stored material. Secondly, after all the material storage monitoring devices 315 monitor the intermediate air separation charging barrel 110, the material blocking driving device 314 is started to drive the material storage baffle 313 to do linear reciprocating motion, all the materials are put into the material separation charging barrel 321 together, and the material storage baffle 313 is enabled to recover the original position. Then, since the output port of the material storage barrel 311 is located above the input port of the material separating barrel 321, the material separating baffle 323 blocks the output port of the material separating barrel 321, so that the material is temporarily stored in the material separating barrel 321. Finally, since the output port of the material distribution barrel 321 is located above the material feeding cavity 410, when the material distribution monitoring device 325 monitors that the material feeding device 4 reaches the position below the material distribution barrel 321, the material distribution driving device 324 is started to drive the material distribution baffle 323 to do linear reciprocating motion, all the materials are put into the material feeding cavity 410 together, and the material distribution baffle 323 is restored to the original position, so that the primary material distribution is completed.
