The output shaft of reduction box；The internal face in the barrel stage casing provided with several along the barrel axial direction arrangement, for shearing
The shearing flange of material, the side of the helicla flute of the screw rod be provided with it is uniformly being arranged along the helicla flute, for shearing material
Shear groove.
Specifically, towards the screw rod head end direction, it is each it is described shearing flange radial thickness taper into.
Specifically, the distance of the two neighboring shearing flange is less than the pitch of the screw rod.
Specifically, the cross section of the shearing flange is trapezoidal.
Specifically, the rotating shaft of the shear groove from outer genesis towards the screw rod of the screw rod extends, and the shearing is recessed
The ratio between thickness of the length of groove and the helicla flute is a, 0.5≤a≤0.75.
Specifically, the shear groove is deep-slotted chip breaker.
The beneficial effects of the utility model are：
When material enters feeding cylinder stage casing（I.e. aforementioned melt section）When, because the internal face in barrel stage casing is provided with several edge material
Shearing flange axial direction arrangement, for shearing material of cylinder, during material is by transmission, shearing flange is to the outer of material
Play intensive shear effect in portion so that material produces more heats.In addition, the side of the helicla flute of screw rod is provided with along helicla flute
Shear groove uniformly arrange, for shearing material.Thus, during screw rod is rotated, shear groove also rises to material
To shear action, so as to further make material produce heat, so that material is in the stage casing of barrel（That is melt zone）Melting
Degree is greatly improved.

5. screw rod, 51. shear grooves, 6. reduction boxes, 7. motors.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with the accompanying drawings.
Fig. 1 and Fig. 2, a kind of single screw extrusion machine that the present embodiment is provided, including pedestal 1 are seen, located at the heating chamber of pedestal 1
2, barrel 3 is fixedly provided with heating chamber 2.Charging bucket 4 is connected with the upside of the afterbody of barrel 3.Barrel 3 is rotationally equipped with
Screw rod 5.Pedestal 1 is additionally provided with motor 7 and reduction box 6, and motor 7 is connected to the input shaft of reduction box 6, and the tail end of screw rod 5 is connected to
The output shaft of reduction box 6.With reference to Fig. 3, the internal face in the stage casing of barrel 3 provided with several along barrel 3 it is axial direction arrangement, for cutting
The shearing flange 31 of material is cut, with reference to Fig. 4 and Fig. 5, the side of the helicla flute of screw rod 5 is provided with uniformly arranged along helicla flute, use
In the shear groove 51 of shearing material.When material enters the stage casing of feeding cylinder 3（That is melt zone）When, due to the internal face in the stage casing of barrel 3
Shearing flange 31 axial direction arrangement, for shearing material provided with several along barrel 3, during material is by transmission,
Shearing flange 31 plays intensive shear effect to the outside of material so that material produces bigger heat.In addition, the spiral shell of screw rod 5
The side of spin slot is provided with shear groove 51 uniformly arranged along helicla flute, for shearing material.The mistake thus rotated in screw rod 5
Cheng Zhong, shear groove 51 also plays shear action to material, so as to further make material produce heat, so that material is in material
The stage casing of cylinder 3（That is melt zone）Melting degree greatly improve.
Specifically, towards screw rod 5 head end direction, the radial thickness of each shearing flange 31 is tapered into, due to screw rod 5
The space edge of helicla flute is tapered into towards the direction of the head end of screw rod 5, also, about close to the head end of screw rod 5, the melting degree of material
It is higher, thus, the radial thickness of each shearing flange 31 is tapered into and can changed in response to the change of material state, while can
Avoid hindering the movement of semi-molten material.
Specifically, the distance of two neighboring shearing flange 31 is less than the pitch of screw rod 5 so that each rotation of screw rod 5, screw rod
Material in 5 helicla flutes will undergo the shear action of two shearing flanges 31 so that material heat is able to comparatively fast be lifted.
Specifically, the cross section of shearing flange 31 is trapezoidal（See Fig. 3）So that shearing flange 31 can to material produce compared with
Big shearing force.
Specifically, rotating shaft of the shear groove 51 from the outer genesis of screw rod 5 towards screw rod 5 extends, the length of shear groove 51 with
The ratio between depth of helicla flute is a, and a=0.6 so that the length of shear groove 51 is moderate is playing a part of strengthening shearing material
Simultaneously, it is to avoid spiral trench bottom damaged.
Specifically, shear groove 51 is deep-slotted chip breaker so that during screw rod 5 drives material movement, material being capable of phase
To easily sliding into shear groove 51 or being skidded off from shear groove 51, without causing in material lagging shear groove 51, from
And shear groove 51 can be made to maintain enough working spaces to shear material.
Above disclosed is only preferred embodiment of the present utility model, can not limit this practicality with this certainly new
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered
Scope.
