In the use of the present invention, the medicinal solid object of mixed metal powder is poured into feeding device 25, feeding device 25 Feed hopper 2501 is imported medicinal solid object in buffer bin 2503 by the first feeding-passage 2502, in buffer bin 2503 In, blade 2505 sweeps into medicinal solid object in the second feeding-passage 2504 under the driving of intermittent drive mechanism 27, and passes through Second feeding-passage 2504 is fallen on conveyer belt 2601, and due to the operating with conveyer belt 2601, medicinal solid object is falling into biography The heaped-up of strip can be presented when sending on band 2601, it therefore, can be equal when medicinal solid object is sent at uniformity plate 29 Even plate 29 is spread out, so that the thickness for being spread out in medicinal fixture on conveyer belt 2601 is thinning, then by conveyer belt 2601 and Gap between even plate 29.Due to the inside of driven voller 2603 be equipped with the first magnet 2604, when medicinal solid object run to from When at dynamic roller 2603, the metal powder quilt having been made thinner due to medicinal solid object, thus be mixed in medicinal solid object by uniformity plate It is adsorbed on the surface of conveyer belt 2601, as conveyer belt 2601 continues to run, and medicinal solid object then eventually falls in the first medicine On allusion quotation sieve 12.For metal powder in the operation of conveyer belt 2601, the first magnet of distance 2604 is increasingly remoter, thus by first The gravitation of magnet 2604 is smaller and smaller, finally loses the gravitation of the first magnet 2604, falls into metal from the surface of conveyer belt 2601 In powder collecting box 30, since the inside of metal powder collecting box 30 is equipped with the second magnet 31, metal powder is in the second magnet 31 Under gravitation, can accurately it fall into metal powder collecting box 30.When needing to outwell the metal powder in metal powder collecting box 30, only It needs to remove metal powder collecting box 30 from device noumenon 1, and powers off, at this point, the second magnet 31 loses magnetism, it is convenient Remove metal powder.The present invention is driven blade 2505 by intermittent drive mechanism 27, so that medicinal fixture is falling into biography The amount on band 2601 is sent to reduce, it, can be by medicinal solid object bulk deposition on conveyer belt 2601 when preventing continuously feeding The phenomenon that.
After the completion of Weeding, start the second servo motor 18, the second servo motor 18 drives driving wheel 11 to turn clockwise Dynamic, when driving wheel 11 rotates clockwise 180 degree, drive rod 10 is moved down, so that three-level screening mechanism is whole It moves down, under the action of rolling cylinder 16, so that three-level screening mechanism is moved up and down with good stability, and three-level Skew will not occur for the position of screening mechanism, and when driving wheel 11 rotates clockwise 360 deg, three-level screening mechanism is completed One process moved up and down, it is this to move up and down the manual material shaking movement for having imitated professional pharmacist, so that three-level screening mechanism Interior material is sieved well.
After sieving, thicker material is located on the first pharmacopeia sieve 12, and medium material is fallen in the second pharmacopeia sieve On 121, and most thin material is fallen in splicing pallet 7, the first pharmacopeia sieve 12 of setting, the second pharmacopeia sieve 121 and is connect Material torr disk 7 forms three-level sub-material, and primary screening obtains three kinds of different degrees of materials, at this point, door-plate is opened, after screening Material carries out transfer or operates in next step.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
