Description
Technical field
The utility model belongs to screw technique field, and in particular to a kind of screw rod of extruder.
Background technology
Extruder is used to that a variety of particulate materials be sufficiently mixed after extruding and export, and is used primarily in plastics or rubber system
Make field.Domestic extruder output is very big now, but technology content is not high, and value-added content of product is not high, the pass of extruder
Key technology is screw rod, and feed end one end of screw rod is communicated with feed inlet, when material is from feed inlet into fashionable, screw feed section
Screw thread piece depth is too shallow to cause material charging rate slow, and is easily blocked in cylinder, be unfavorable for material and march forward, existing
Screw flight design it is unreasonable.
Utility model content
The purpose of this utility model is to provide a kind of raising charging rate, is not easy the screw rod of extruder to get stuck.
The technical solution of the utility model is：A kind of screw rod of extruder is provided, the screw rod includes feeding section, compression
Section, homogenizing zone, the homogenizing g. slice header are connected with mixing refining head, and the charging section surface is equipped with feeding section screw thread piece, the compression section
Surface is equipped with compression section screw thread piece, and the homogenizing section surface is equipped with homogenizing zone screw thread piece, the depth of the feeding section screw thread piece from
Close to feed inlet to shoaling successively away from feed inlet direction, the depth of the feeding section screw thread piece is deeper than the compression section screw thread
The depth of piece and the homogenizing zone screw thread piece, the feeding section screw thread piece, compression section screw thread piece, homogenizing zone screw thread piece and screw thread sheet
The inclined direction of body and angle of inclination are identical.
Preferably, the screw surface is coated with anticorrosion material.
Preferably, the inside screw is closed equipped with one end, the other end cooling duct identical with cooling device.
Preferably, the mixing refining head is equipped with multigroup mixing formation, and it is recessed that every group of mixing formation includes axially distributed first
Slot, the second groove and the 3rd groove.
Preferably, one end of first groove extends to feeding section, and one end of second groove extends to homogenizing zone,
3rd groove is located between the first groove and the second groove and is communicated with the two.
Preferably, the bottom of first groove, the second groove and the 3rd groove is equipped with raised line, and the raised line length is equal
Less than the slot length of the first groove, the second groove and the 3rd groove.
The beneficial effects of the utility model are：The utility model feeding section screw thread piece depth from depth to shallow, work as material
When falling into the groove between screw thread piece, more materials can be accommodated and entered, blanking speed is accelerated, and then improve extrusion
Efficiency, and the depth of gradual change is conducive to material and screw advancement direction is followed to advance, and will not block charge door.
Description of the drawings
Fig. 1 is the screw-rod structure schematic diagram of the utility model extruder.
