The arrangement of a plurality of first screen plates 41 and a plurality of second screen plates 42 for the plastic particles is in the slip in-process, along with the switching of plastic particle bottom screen plate, the screen is mutually impacted with subsequent screen plate, thereby make the plastic particles take place great vibrations, shake the dust that plastic particles surface is attached off, the arrangement of a plurality of fans 45 and filter 46, the top that makes first screen plate 41 and second screen plate 42 has the air current that blows to the screen plate direction perpendicularly, thereby can release the plastic particles that blocks up in the hole of first screen plate 41 and the plastic particles that blocks up in the hole of second screen plate 42 after the plastic particles cooling shrink, the setting of baffle 48 can restrict the falling position of the plastic particles of shell 2 bin outlet department discharge, and the setting of discharge pipe 47 can be with suitable size plastic particles and other plastic particles separation direction.

The implementation principle of the embodiment is as follows: when screening plastic particles, firstly, the fan 45 is started, and the rotating fan 45 continuously pushes part of the gas in the gas inlet pipe 43 into the shell 2, and as the gas in the gas inlet pipe 43 passes, the top of the gas inlet pipe 43 forms a negative pressure state, so that the external gas flows into the gas inlet pipe 43 through the holes of the filter screen 44 to supplement the gas in the gas inlet pipe 43;

It should be noted that, when the external air passes through the holes of the filter screen 44, dust in the external air can be blocked outside the air inlet pipe 43;

A small part of the gas entering the shell 2 flows out of the shell 2 through the holes of the first sieve plate 41, the holes of the second sieve plate 42 and the holes of the filter plate 46, and a large part of the gas is discharged into the baffle 48 and the discharge pipe 47 along the first sieve plate 41, the second sieve plate 42 and the filter plate 46 from the discharge hole of the shell 2 and finally discharged to the outside;

After the gas flow line in the shell 2 is formed, plastic particles are led into the storage vat 31, the plastic particles entering the storage vat 31 slide along the inner wall of the storage vat 31 and are gathered into the rectangular pipe 32, then fall into the shell 2 at a certain speed, the plastic particles falling into the shell 2 impact on the first screen plate 41, and move towards the discharge opening of the shell 2 along the first screen plate 41 due to the elastic bouncing of the plastic particles, at the moment, the plastic particles with proper size fall onto the second screen plate 42 through holes of the first screen plate 41 and move towards the discharge opening of the shell 2 along the second screen plate 42, and meanwhile, the plastic particles with too small volume fall onto the filter plate 46 through the second screen plate 42 and move towards the discharge opening of the shell 2 along the filter plate 46;

according to the above, during the process of moving the plastic particles along the first screen plate 41, the second screen plate 42 and the filter plate 46, the air flow flowing in the housing 2 towards the discharge opening of the housing 2 will assist to push the plastic particles to move towards the discharge opening of the housing 2;

Meanwhile, the air flow flowing towards the direction of the filter plate 46 enables plastic particles to roll on the first screen plate 41, the second screen plate 42 and the filter plate 46 in a manner that the plastic particles move on the top side of the first screen plate 41, the top side of the second screen plate 42 and the top side of the filter plate 46 are clung to each other, when the plastic particles pass through holes, the plastic particles generate small-amplitude vibration, dust attached to the surfaces of the plastic particles is vibrated off, and when the plastic particles move from the right first screen plate 41 or the second piston plate to the next screen plate, the plastic particles vibrate to a large extent due to the impact of the plastic particles with the first screen plate 41 or the second screen plate 42, the dust attached to the surfaces of the plastic particles is vibrated off again, and finally the vibrated dust is rapidly discharged out of the shell 2 along with the air flow;

According to the above, when the plastic particle screening operation is performed, the small-caliber storage box is sleeved at the bottom end of the discharge pipe 47, the large-caliber storage box is placed below the baffle 48, the plastic particles with proper size sliding out of the shell 2 between the first sieve plate 41 and the second piston plate are guided into the small-caliber storage box for storage through the discharge pipe 47, and the plastic particles with improper size sliding out of the shell 2 fall into the large-caliber storage box for storage through the blocking of the baffle 48 above the first piston plate and below the second sieve plate 42, so that the plastic particles are continuously guided into the storage barrel 31 for sustainable plastic particle screening;

When the holes of the first screen plate 41 or the holes of the second screen plate 42 are blocked, the blocking of the plastic particles in the holes of the first screen plate 41 or the holes of the second screen plate 42 is gradually pushed out of the holes due to the pushing of the air flow flowing toward the direction of the filter plate 46.

The embodiments of the present utility model are all preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
