It is distributed the first sieve pore 2 before baffle 3, baffle 3 is to being distributed the second sieve pore 5 between 4 low side of hopper.The aperture of first sieve pore 2 is less than
The aperture of second sieve pore 5, the first sieve pore 2 are miscellaneous for the lesser plastic grain of Sieving and casing and the powder being mixed in plastic grain
Matter, the second sieve pore 5 is for sieving plastic particle finished products.Offer the reclaiming chamber for collecting above two plastic grain in screen box 6, two
A reclaiming chamber is located at the lower section of the first sieve pore 2 and the second sieve pore 5.And weldering is equipped with and two times respectively on 6 side wall of screen box
Receive the feeder pipe of chamber connection.
The low side of hopper 4 is horizontally installed with blanking sieve plate 8, and several second sieve pores 5 are also offered on blanking sieve plate 8.Blanking
8 both ends of sieve plate are welded with shaft 9, and two shafts 9 are rotatably connected on respectively on the side wall of hopper 4.The connection of 8 bottom of blanking sieve plate
There is the force piece for driving it to rotate, force piece uses cylinder in the present embodiment, in 16 bar of piston and blanking sieve plate 8 of cylinder
The bottom of side offsets.4 bottom of hopper of the lower section of blanking sieve plate 8 offers opening and is connected to screen box 6, blanking sieve plate 8 and hopper 4 it
Between be provided with for preventing plastic grain from falling to the protection mechanism in screen box 6.In conjunction with Fig. 2 it is found that protection mechanism includes protection
Cloth 7, protective cloth 7 use existing plastic cloth or common cloth.4 low side of hopper laterally offers connecting hole 11, protective cloth 7 one
End is bolted in 8 inside side walls of blanking sieve plate, the other end passes through connecting hole 11 and is located at 4 lower section of hopper, and protective cloth 7
One end positioned at 4 lower section of hopper is connected with weight linear meter 12, and protective cloth 7 can be used the connectors such as bolt and be fixed on weight linear meter 12.
Specific implementation process is as follows:
When start-up operation, feeding cylinder 1 is opened, plastic grain enters in hopper 4 from feeding cylinder 1.Start driven by vibrating motors
Screen box 6 vibrates, and screen box 6 drives hopper 4 to vibrate, and the plastic grain in hopper 4 vibrates.Start under cylinder interval jack-up simultaneously
The inside of material screen plate 8, so that blanking sieve plate 8 flips outward.Plastic grain from the high-end gradually slide downward of hopper 4, sliding
In the process, dust and the plastic grain of small particle pass through the first sieve pore 2 and fall in screen box 6 reclaiming chamber.It can not wear
The plastic grain for crossing the first sieve pore 2 continues slide downward, and plastic particle finished products fall to another in screen box 6 across the second sieve pore 5
In one reclaiming chamber.
The plastic grain of agglomeration can not pass through the second sieve pore 5, therefore slide at blanking sieve plate 8 during vibration.
Instantly when material screen plate 8 turns to concordant with the bottom of hopper 4, the plastic grain of agglomeration can be slid on blanking sieve plate 8；Work as gas
When cylinder driving blanking sieve plate 8 turns to state as shown in Figure 1, the plastic grain to agglomerate on blanking sieve plate 8 can be along blanking
Inclined plate 10 is discharged.
Due to being connected with protective cloth 7 between blanking sieve plate 8 and hopper 4, blanking sieve plate 8 can pull out protective cloth 7 when overturning,
Protective cloth 7 blocks between blanking sieve plate 8 and hopper 4, can prevent the plastic grain of agglomeration from falling in screen box 6.Protective cloth 7
Across connecting hole 11 and it is connected with weight linear meter 12, when blanking sieve plate 8 is overturn, weight linear meter 12 can tense protective cloth 7, blanking sieve plate
8 when resetting, and weight linear meter 12 can also withdraw protective cloth 7 so that protective cloth 7 be tightened in always blanking sieve plate 8 and hopper 4 it
Between, it can prevent plastic grain pocket in protective cloth 7.In addition, when practice be adjusted blanking sieve plate 8 overturn angle or
It is the length of protective cloth 7, weight linear meter 12 is pulled to by blanking sieve plate 8 when overturning and is offseted with 4 bottom of hopper, it is thus sharp
Hopper 4 is hit with weight linear meter 12, thus the case where mitigating sieve pore blockade.
Embodiment two
As shown in Figure 3 and Figure 4, the present embodiment and embodiment one the difference is that, be equipped in hopper 4 for modeling
Expect the cooling mechanism of particle cooling.Cooling mechanism includes the inflatable chamber 17 being provided in 4 side wall of hopper, is connected on the inside of inflatable chamber 17
There is escape pipe 13, escape pipe 13 is arranged towards feeding cylinder 1.Piston 16, piston 16 and inflatable chamber are slidably connected in inflatable chamber 17
Reset spring 15 is connected between 17 tops.Piston 16 is connected with the driving mechanism for driving it to slide, and driving mechanism includes
The gear set being mounted in 4 side wall of hopper, gear wheel 21 and shaft 9 in gear set are keyed, the pinion gear 20 in gear set
It is coaxially connected with winding roller 19, bracing wire 18 is connected between winding roller 19 and piston 16.It is also equipped in hopper 4 for stirring modeling
Expect that the driving lever 14 of particle, driving lever 14 are extended in 4 side wall of hopper and connect with bracing wire 18.Specifically, can be opened up on driving lever 14 logical
Hole is passed through for bracing wire 18, is achieved in the connection of bracing wire 18 Yu driving lever 14.
During practice, shaft 9 is driven to rotate when blanking sieve plate 8 rotates, shaft 9 drives gear wheel 21 to rotate,
Gear wheel 21 drives 20 quick rotation of pinion gear engaged.Pinion gear 20 drives the winding roller 19 coaxially connected quick
Take-up, piston 16 is pulled downward on by bracing wire 18, reset spring 15 is stretched.When blanking sieve plate 8 resets, winding roller 19 is anti-
Line is relayed, piston 16 is released, and reset spring 15 drives the quick upward sliding of piston 16, thus by the gas in inflatable chamber 17
It is squeezed out from escape pipe 13, the gas of extrusion cools down to plastic grain, can reduce the case where plastic grain is bonded.
Under original state, the state of driving lever 14 is as shown in figure 3, therefore driving lever 14 will not influence plastic grain slide downward.
Driving lever 14 can be located at one end in 4 side wall of hopper by bracing wire 18 when 19 take-up of winding roller to pull downward on；Winding roller 19 is put
Driving lever 14 resets when line, so that driving lever 14 is swung in hopper 4.The plastic grain in hopper 4, energy are stirred using driving lever 14
Enough improve the effect of plastic grain screening.
The present invention realizes the discharge of agglomeration plastic grain by the driving overturning of blanking sieve plate 8, without manually stirring agglomeration
Plastic grain alleviates labor intensity.In addition, the present invention can also cool down and stir to plastic grain, improve
The effect of plastic grain screening.
Embodiment three
As shown in figure 5, the present embodiment and embodiment one the difference is that, haltere 22 is installed on hopper 4, is balanced
Stick 22 is arranged across hopper 4, and 22 left end of haltere is arranged wire, and welded wire is on screen box 6.22 right end of haltere passes through
Lock is fixed on hopper 4.By lock fastening haltere 22 when use, it is pressed on it on hopper 4, hopper 4 can be reduced
Oscillation Amplitude, avoid the excessive plastic grain caused in it of 4 Oscillation Amplitude of hopper from splashing.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as specific embodiment can be used for explaining the content of claim.
