Description
Technical Field
The utility model belongs to the technical field of the extruder manufacturing technique and specifically relates to a shell and sleeve machine screw rod is related to.
Background
Screw rod: a cylinder with a spiral groove or a cone with a conical spiral groove on the outer surface; the screw is mainly used in plastic molding equipment, such as a plastic profile extruder, an injection molding machine and engineering plastic injection molding, and is a core component of the plastic molding equipment, a part for heating, extruding and plasticizing, and a core component of a plastic machine in the whole engineering plastic injection molding.
But because the screw rod that has now all adopts the body of rod and sets up the screw thread on the body of rod to constitute, and the interval between the screw thread is unanimous for in the middle of the process of the ejection of compact, the melting material in the feed cylinder can't obtain abundant even stirring and mix, makes the effect of moulding plastics not good, makes technology plastics product produce a large amount of bubbles in the middle of injection moulding's process easily, thereby has reduced the quality of shaping engineering plastics by a wide margin, and the practicality is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned prior art current situation and provide a shell cover machine screw rod that the material is sheared fast, is heated evenly and the plastify is efficient.
The utility model provides a technical scheme that above-mentioned technical problem adopted does:
the screw rod of the shell machine comprises a rod body, wherein the rod body is sequentially composed of a feeding section, a melting section, a homogenizing section and an extruding section, the melting section comprises a melting section body and a first spiral edge, the first spiral edge is fixed on the periphery of the melting section body, and the melting section body is provided with cutting blocks which are arranged in an S shape.
The sectional view of the dividing block is a diamond shape, and the height of the dividing block is consistent with that of the first screw edge.
The first screw ridge is integrally formed with the melting section.
The homogenizing section is provided with disconnected and uniformly distributed screw-breaking edges, and the screw-breaking edges are matched with screws in a screw machine barrel.
The extrusion section comprises an extrusion section body and a second spiral edge, the second spiral edge is axially arranged, the second spiral edge is low in the middle and high in two ends, or is high in the middle and low in two ends, or simultaneously comprises a structure with the middle and high in the two ends and the middle and low in the two ends.
The second spiral pitch is 50-55 mm.
Has the advantages that: because be equipped with on the melting section body and cut apart the piece and be the S type and arrange for a plurality of segmentation pieces can be effectual stir the melting material, make the melting material mix more evenly, can not produce the bubble for the transmission of melting material has improved the quality of shaping engineering plastics, and the practicality is strong.

The rod body 1, the material feeding section 2, the melting section 3, the homogenizing section 4, the extruding section 5, the first screw ridge 6, the dividing block 7, the broken screw ridge 8 and the second screw ridge 9.
Detailed Description
The invention will be further described with reference to the following examples.
The embodiment of the utility model provides a shell machine screw rod, including the body of rod 1, this body of rod 1 is in proper order by reinforced section 2, melting section 3, homogenization section 4, extrude the section 5 and constitute, melting section 3 includes melting section body and first spiral arris 6, first spiral arris 6 is fixed in the periphery of melting section body, it cuts apart piece 7 to be equipped with on the melting section body, it is arranged that it is the S type to cut apart piece 7, owing to be equipped with on the melting section body and cut apart piece 7 and be the S type and arrange for a plurality of cutting apart piece 7 can be effectually stir the melting material, makes the melting material mix more evenly, can not produce the bubble for the transmission of melting material has improved the quality of shaping engineering plastics, and the practicality is strong.
The cutting block is positioned at the rear half section of the melting section body, the melting is ensured at the front half section, and the uniformity is ensured at the rear half section.
The section of the dividing block 7 is in a rhombic shape, the material can be separated and folded due to the arrangement of the rhombic shape, the molten material can be mixed more uniformly, and the height of the dividing block 7 is consistent with that of the first screw ridge 6.
The first screw rib 6 is integrally formed with the melting section 3.
The homogenizing section 4 is provided with disconnected uniformly-distributed broken screw ribs 8, the broken screw ribs 8 are matched with screws in the screw machine barrel, the homogenizing section 4 is provided with disconnected uniformly-distributed broken screw ribs 8, the broken screw ribs 8 of the screw are matched with the screws in the screw machine barrel, the structure is favorable for shearing of molten materials, and the material stagnation time is shortened, so that the decomposition of the materials is reduced, the production efficiency and the plasticizing efficiency are improved, the structure can enable the materials to be heated uniformly during melting, the materials are not easy to burn, and the working effect is better.
The distance between the second spiral edges 9 is 50-55 mm.
Extrude section 5 including extruding section 5 body and second spiral shell arris 9, second spiral shell arris 9 axial sets up, second spiral shell arris 9 is low for the high both ends in middle part, or for the low both ends in middle part height, perhaps including the high both ends in middle part height structure low with the low both ends in middle part height simultaneously, this structure makes the screw rod have sufficient space and time to avoid putty and burnt material.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
