The wind of blower fan 91 circulates upwards from the bottom of the first screen cloth 5 through sieve aperture, prevented also from the first screen cloth 5 sieve aperture by plastic pellet
Block.
For influence of the jump to blower fan 91 of being quivered when preventing the drive hopper 3 of vibrating motor 4, in the air outlet of blower fan 91 and enter tuyere
A muslin tubing 94 is also communicated between 92；The both ends of muslin tubing 94 are socketed in the air outlet of blower fan 91 and entered on tuyere 92 respectively, together
When be fixed by the inlay card of snap ring 95 at the both ends of muslin tubing 94 and by bolt and nut group；Blower fan is made by muslin tubing 94
91 air outlets are flexibly connected into tuyere 92, it is therefore prevented that hopper 3, which quivers, jumps damage to motor.
When vibratory sieve works, by manually rotating crank 12, scraper plate 112 is set to be overlapped on monosymmetric shell fragment 532
On, so as to which the plastic pellet not influenceed on the first screen cloth 5 falls into the second screen cloth 6, and after the completion of the work of vibratory sieve gradation, then revolve
Turn crank 12, because shell fragment 532 has certain deformability, the support of shell fragment 532 is departed from so as to scraper plate 112 to be made to scrape portion
The 1121 first upper surfaces with the second screen cloth 6, with the rotation of crank 12, connecting rod 111 can slide elasticity simultaneously upwards
The compression of part 113 is allowed to produce elastic force, and elastic force reacts on scraper plate 112, make to scrape portion 1121 further with the second screen cloth 6
Upper surface is bonded, and scrapes more efficient, while is scraped portion 1121 and is slid and promote agglomerate material from second in the upper surface of the second screen cloth 6
Material mouth is discharged；Because the length of scraper plate 112 is equal to the width of the second screen cloth 6 so that scraper plate 112 is whole to the upper surface of the second screen cloth 6
Body all plays cleaning, plays and preferably scrapes effect；
For the ease of collecting the pellet in small, broken bits that the first screen cloth 5 filters out, the first discharging opening 33 is offered in the side of hopper 3,
First discharging opening 33 communicates with storing passage 93, the pellet in small, broken bits discharge material that the first discharging opening 33 is used under the first screen cloth 5 is filtered
Groove 3；An open and close door is hinged with by hinge at the first discharging opening 33, open and close door is provided with leader；Operating personnel pass through handle
Hand can easily open and close the first discharging opening 33, prevent blower fan 91 at work, and the pellet in small, broken bits in storing passage 93 is blown
One discharging opening 33；Second discharging opening 34 is used to will be unable to the agglomerate material discharge hopper 3 for filtering the second screen cloth 6；Positioned at the on hopper 3
The bottom of two screen clothes 6 is further opened with the 3rd discharging opening 35, and the 3rd discharging opening 35 is used for the qualified plastic pellet for filtering out the second screen cloth 6
Son discharge hopper 3.
Operation principle and process：The plastic pellet that high speed grain-cutter is cut out is delivered to the first screen cloth 5 by feed hopper 8, is shaken simultaneously
The blower fan 91 of dynamic motor 4 and cooling device works, and vibrated motor 4 drives, and plastic pellet is under the drive of vibration device the
Upper and lower jump of quivering on one screen cloth 5, while the first screen cloth 5 filters out the pellet in small, broken bits in plastic pellet, because vibrating motor 4 is fixed on
Close to one end of feed hopper 8 so that plastic pellet of first screen cloth 5 close to the one end of feed hopper 8 quivers jump floating greatly, and then drives modeling
Material particle quivers jumps toward one end away from vibrating motor 4, and then so that plastic pellet falls into the second screen cloth 6, qualified plastic pellet
Filtered out through the second screen cloth 6, discharge and collect from the 3rd discharging opening 35, entered back into down and mix process thoroughly together and mix thoroughly；And shake crank 12
Then the agglomerate material being deposited on the second screen cloth 6 can be discharged hopper 3 from the second discharging opening 34.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
