Abstract
The utility model relates to the technical field of screws, in particular to an improved extrusion screw. The improved extrusion screw comprises a feeding section, a fusing and plasticizing section and an extrusion section, wherein a plurality of guiding holes are axially formed in the threads of all the feeding section, the fusing and plasticizing section and the extrusion section, and guiding extending edges are arranged on the outer edges of the threads of all the feeding section, the fusing and plasticizing section and the extrusion section in an extending way. Through the axial forming of the guiding holes in the threads of all the feeding section, the fusing and plasticizing section and the extrusion section and the extending arrangement of the guiding extending edges on the outer edges of the threads, a material can flow along the set motion track, the constant-speed flowing of the material can be ensured, the flowing track is regular and smooth, and the extrusion quality of the material cannot be influenced.
Description
Technical field
The utility model relates to screw technique field, relates in particular to a kind of improved extrusion screw rod.
Background technology
At present; in prior art, in extruder screw, generally only there is the effect of feeding; in carrying out the process of extruded material; because becoming irregular track, material flows in machine barrel; so often, there will be, there is sometimes fast and sometimes slow phenomenon in the flow velocity of material, therefore material easily produces stagnation or material flow is too fast; fail the thoroughly situation of plasticizing, can have a strong impact on like this quality of extruding of material.
Utility model content
The purpose of this utility model is to provide a kind of improved extrusion screw rod, and it has can guarantee that material is at the uniform velocity mobile, and flow trace is regular and smooth and easy, can not affect the feature that material is extruded quality.
For achieving the above object, the utility model adopts following technical proposals:
A kind of improved extrusion screw rod, comprise feed zone, fusion plastification section and extruding zone, the screw thread of described feed zone, fusion plastification section and extruding zone all axially offers some pod apertures, and all extension being provided with water conservancy diversion prolongs limit in the screw thread outside of feed zone, fusion plastification section and extruding zone.
Wherein, described pod apertures is for to prolong the corresponding angling hole of offering in limit with water conservancy diversion, and between angling hole and the axis of extrusion screw rod, angle is 45 °.
Adopt after said structure, the beneficial effects of the utility model: the utility model comprises feed zone, fusion plastification section and extruding zone, described feed zone, the screw thread of fusion plastification section and extruding zone all axially offers some pod apertures, feed zone, all extension being provided with water conservancy diversion prolongs limit in the screw thread outside of fusion plastification section and extruding zone, the utility model passes through at described feed zone, the screw thread of fusion plastification section and extruding zone all axially offers some pod apertures, and in screw thread outside, all extend and be provided with water conservancy diversion and prolong limit, can make material movement locus according to the rules flow, can guarantee that like this material is at the uniform velocity mobile, flow trace is regular and smooth and easy, can not affect material and extrude quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, Reference numeral comprises:
1, feed zone; 2, fusion plastification section;
3, extruding zone; 4, pod apertures;
5, water conservancy diversion prolongs limit.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of improved extrusion screw rod, comprise feed zone 1, fusion plastification section 2 and extruding zone 3, the screw thread of described feed zone 1, fusion plastification section 2 and extruding zone 3 all axially offers some pod apertures 4, all extension being provided with water conservancy diversion prolongs limit 5 in the screw thread outside of feed zone 1, fusion plastification section 2 and extruding zone 3, described pod apertures 4 is for to prolong the corresponding angling hole of offering in limit 5 with water conservancy diversion, and between angling hole and the axis of extrusion screw rod, angle is 45 °.By the screw thread at described feed zone 1, fusion plastification section 2 and extruding zone 3, all axially offer some pod apertures 4, and in screw thread outside, all extend and be provided with water conservancy diversion and prolong limit 5, water conservancy diversion prolongs limit 5 and can be extended out screw thread outside, to expand the flowing space of material, the utility model can make material movement locus according to the rules flow, and can guarantee that like this material is at the uniform velocity mobile, and flow trace is regular and smooth and easy, can avoid material to flow backwards, can not affect material and extrude quality.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
Claims (2)
1. an improved extrusion screw rod, comprise feed zone, fusion plastification section and extruding zone, it is characterized in that: the screw thread of described feed zone, fusion plastification section and extruding zone all axially offers some pod apertures, all extension being provided with water conservancy diversion prolongs limit in the screw thread outside of feed zone, fusion plastification section and extruding zone.
2. a kind of improved extrusion screw rod according to claim 1, is characterized in that: described pod apertures is for to prolong the corresponding angling hole of offering in limit with water conservancy diversion, and between angling hole and the axis of extrusion screw rod, angle is 45 °.
