It is cooled and bonding will not occur thus blocking the problem of conveying passage, so do not need to reduce pelletize yield.
Preferably, as another kind of embodiment, referring to Fig. 4, being additionally provided with gear at the opening of described wind conveying pipe 120
Plate 140, one end 141 of described baffle plate 140 is fixed on the inwall of described cover body 110, and the other end 142 of described baffle plate 140 hangs
There is gap between sky, and the other end 142 of described baffle plate 140 and the inwall of described cover body 110.Setting baffle plate 140 can change
Become air intake direction, air intake changes after deep bead gap (lip) between baffle plate and the inwall of grain cutting cover for the path and obtains
Release, now air intake along grain cutting cover inwall formed vane, the fervent plastic pellet of flour milling can incorporate moment vane obtain cold
But, enter feed system through the tangentially discharging opening from grain cutting cover lower end.Baffle plate can also change air quantity and the blast of air intake simultaneously.
Described gap is preferably 2～5cm.So ensure that the vane that air intake is formed is completely covered the fervent of the fervent formation of flour milling
Grain.
More preferably, referring to Fig. 4, described baffle plate 140 is curved baffle.Curved baffle can make air intake along in grain cutting cover
Wall rotation forms rotary wind ring, and hot cut pellet can more rapidly dissolve in rotary wind ring, and the pelletizing after simultaneously cooling down is in rotation
The discharging opening 101 of grain cutting cover can be fallen to along grain cutting cover in the presence of vane.
Further, referring to Fig. 4, described curved baffle 140 protrudes to the side away from described wind conveying pipe 120.Namely
Say that the end of the centre distance wind conveying pipe of curved baffle is farthest.Such curved baffle is most beneficial for formation vane.
Wind conveying pipe in this utility model can be arranged on any position on cover body, and the shape of cover body can be existing
The cover body of water-drop-shaped.Preferably, referring to Fig. 4, described cover body 110 includes first straight line section 111, arc 112 and second straight line
Section 113, one end of first straight line section 111 is connected with arc 112, and the other end of arc 112 is with second straight line section 113 even
Connect, described wind conveying pipe 120 is arranged in described first straight line section 111 or described second straight line section 112.In grain cutting cover first is straight
Circular hole welding wind conveying pipe is opened on line segment or second straight line section.Grain cutting cover in the present embodiment and the pelletizing of the current water-drop-shaped using
Cover is identical, because cover body is upside down, wind conveying pipe is arranged in first straight line section or second straight line section that is to say, that defeated
Airduct is located at the lower section of cutting knife unit, and such air intake moves from bottom to top, and hot cut pellet falls from the top down, air intake and hot cut pellet
Reverse movement is such that it is able to reach more preferable cooling effect.First straight line section in Fig. 4 and second straight line section are symmetrical arranged.
Preferably, as another kind of embodiment, the cover body in the present embodiment be shaped as asymmetrical water-drop-shaped.Ginseng
See Fig. 5, described first straight line section 121 and the asymmetric setting of described second straight line section 123.First straight line section and second straight line Duan Fei
It is symmetrical arranged the volume of the hollow bulb that can increase grain cutting cover on the basis of not increasing materials, thus increased cooling space.
A diameter of 800mm of the grain cutting cover in the present embodiment, thickness is 230mm.
Further, referring to Fig. 5, the cover body 110 in Fig. 5 includes first straight line section 121, arc 122 and second straight line
Section 123, first straight line section 121 and second straight line section 123 are located at the two ends of arc 122, but described the in the present embodiment
The gradient of one straightway 121 is more than the gradient of described second straight line section 123；That is first straight line section 121 with vertically
Angle between line is less than the angle between second straight line section and vertical curve.Described in now described wind conveying pipe 120 is preferably disposed on
In first straight line section 121, so the angle between the air intake of setting wind conveying pipe and the inwall of grain cutting cover is more suitable for.Simultaneously described
Wind conveying pipe 120 be preferably obliquely installed so that air intake closer to and cutting knife unit is completely covered.
More excellent, referring to Fig. 5, angle a between the centrage of described wind conveying pipe 120 and described first straight line section 121 is big
In 90 degree.So setting ensure that the vane of formation advantageously in the cooling of hot cut pellet.
Further, referring to Fig. 5, described grain cutting cover 100 also includes discharging section 150, the centrage of described discharging section 150 with
Angle b between described first straight line section 121 (111) is 80 degree to 140 degree.Discharging section 150 basic horizontal in the present embodiment
Arrange or slope slightly downward setting.Discharging section is seamlessly transitted with first straight line section and second straight line section.Setting discharging section can
Pelletizing is made to slip into discharging section along the inwall of cover body, thus avoiding clashing between pelletizing and grain cutting cover.
Based on same design, this utility model also provides a kind of plastic extrusion granulation system, and it includes plastic extrusion facility
With the plastic granulating equipment described in above-mentioned any embodiment, the grain cutting cover of described plastic granulating equipment is arranged on described plastic extrusion
On the die orifice of equipment；Described rotating spindle is coaxially disposed with the extrusion die of described plastic extrusion facility.Its overall structure and Fig. 1
Compare, mainly the improvement is that grain cutting cover.The work process of plastic extrusion granulation system of the present utility model is that plastics pass through
Extrusion screw rod effect is extruded from extrusion die, and pelletizing main shaft and extrusion die keep concentric, and motor drives rotating spindle to turn
Dynamic, the cutting knife of cutting knife unit is close to flour milling knife through overtension and is cut, and the molten part of plastics is i.e. fervent by flour milling through the nib of extrusion die.
Colding pressing in air quantity input grain cutting cover of air-supply arrangement, changes path through arc wind board and is released from gap, airflow pressure
Make tangential rotary along grain cutting cover inwall and become vane, flour milling fervent plastic pellet moment incorporates vane and cooled down, through tangential
Discharging opening from grain cutting cover lower end enters feed system.
This utility model is flour milling fervent vane cooling granulation, and the type of cooling using vane and in grain cutting cover is by pelletize
Complete in grain cutting cover with pelletizing cooling simultaneously, on the one hand avoid hot cut pellet bonding, on the other hand do not need to arrange civilian mound again
In the device such as pipe, thus saving equipment investment, and almost completely avoid transfer passage blocking.
Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that it is common for this area
For technical staff, without departing from the concept of the premise utility, some deformation can also be made and improve, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
