Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-3, an energy-saving screw extruder comprises an extrusion head 10, wherein two extrusion screws 12 opposite to each other are rotatably connected in an extrusion cavity 11, an extrusion spiral groove 13 is wound on each extrusion screw 12, the depth of each extrusion spiral groove 13 is gradually reduced along the direction close to the outlet of the extrusion head 10, the two extrusion spiral grooves 13 on the two extrusion screws 12 are symmetrically arranged, and a steering component 14 capable of enabling the two extrusion screws 12 to rotate in opposite directions is further arranged in the extrusion head 10.
In the utility model, pour the material into extrude the intracavity 11 and carry out high temperature heating to the material and make the material become the melting material, two extrusion screw 12 rotate and the direction of rotation is different, because two extrusion helical groove 13 mutual symmetry settings on two extrusion screw 12, push the melting material towards same direction, again because the degree of depth that extrudes helical groove 13 reduces gradually along the direction that is close to the export of extrusion head 10, the degree of depth of the partial extrusion helical groove 13 of keeping away from the export of extrusion head 10 is the biggest, consequently in extrusion screw 12 rotates the in-process, the melting material of the crowded push of this part is the most, and the melting material of the crowded push of the extrusion helical groove 13 that is closer to the export of extrusion head 10 reduces gradually, thereby carry out the compaction operation to the melting material, prevent that the melting material of extruding has bubble or cavity, in current technique, often have two rolling cylinders at the tip of extrusion screw 12, the melting material that extrusion screw 12 was extruded carries out the compaction through two cylinders, need provide cylinder and driving roll pivoted motor alone, and the utility model discloses do not need the cylinder just can carry out the compaction to the melting material, have energy-conserving effect.
The density of the extrusion spiral groove 13 is gradually increased along the direction close to the outlet of the extrusion head 10.
In the present invention, although the depth of the extrusion spiral groove 13 is gradually reduced along the direction close to the outlet of the extrusion head 10 to compact the melt, the speed of the extruded material of the extrusion screw 12 is the same as the feeding speed of the material, because the depth of the extrusion spiral groove 13 close to the outlet of the extrusion head 10 is smaller, so that the melt which is pushed out is less, in order to maintain a certain discharging speed, and in order to prevent the extrusion screw 12 from generating a large reaction damage part in the process of compacting the melt, the density of the extrusion spiral groove 13 close to the outlet of the extrusion head 10 is larger, and the moving speed of the melt of the part is increased indirectly.
The extrusion spiral groove 13 is internally provided with a plurality of extrusion plates 15 which are sequentially arranged along the extrusion spiral groove 13.
The extrusion plate 15 can push the melt further during the rotation of the extrusion screw 12, so that more melt is extruded and moves toward the outlet of the extrusion head 10 as the extrusion screw 12 rotates.
The extrusion plates 15 are obliquely arranged on the inner wall of the extrusion spiral groove 13, and the inclination directions of the extrusion plates 15 on the two extrusion screws 12 are opposite.
The utility model discloses in, the incline direction of stripper plate 15 is corresponding with extrusion screw 12's rotation direction, rotates the in-process at extrusion screw 12, and stripper plate 15 rotates along with extrusion screw 12, and the melting material can be piled up in stripper plate 15 and extrusion helicla flute 13's contained angle, and under this state, stripper plate 15 can promote the melting material to make between the melting material extrude each other and carry out the compaction.
The length of the extrusion plate 15 is greater than or equal to the depth of the extrusion spiral groove 13.
In the present invention, the extrusion plate 15 enables more molten materials to be extruded into the extrusion spiral groove 13 and to move forward and be compacted along with the rotation of the extrusion spiral groove 13.
The side of the extrusion cavity 11 is provided with a turning cavity 16 arranged in the extrusion head 10, the turning part 14 comprises a rotating motor 17 arranged in the inner wall of the turning cavity 16, an output shaft of the rotating motor 17 is movably connected with two first helical gears 18 which are mutually symmetrical, the end part of each extrusion screw rod 12 far away from the outlet of the extrusion head 10 is provided with a second helical gear 19, and the two second helical gears 19 are respectively meshed with the two first helical gears 18.
The utility model discloses in, the work of rotating electrical machines 17 makes the output shaft of rotating electrical machines 17 rotate, makes two first helical gears 18 rotate, because two first helical gears 18 symmetry each other, and two second helical gears 19 are connected with one side with two first helical gears 18 to make two second helical gears 19's rotation opposite direction, finally make two extrusion screw 12's rotation opposite direction.
Each extrusion screw 12 is also wound with a flow guide spiral groove 20, and the flow guide spiral groove 20 is arranged in parallel with the extrusion spiral groove 13 on the extrusion screw 12.
The utility model discloses in, water conservancy diversion helicla flute 20 also has the effect of certain crowded melting material that pushes away, improves the ejection of compact speed of melting material, because water conservancy diversion helicla flute 20 and the extrusion helicla flute 13 parallel arrangement that corresponds, water conservancy diversion helicla flute 20 can not intersect with this extrusion helicla flute 13.
The width of the diversion spiral groove 20 gradually decreases along the direction close to the outlet of the extrusion head 10.
Because the density of the part of the extrusion spiral groove 13 close to the outlet of the extrusion head 10 is increased, in order to prevent the excessive discharge speed of the molten material at the part from causing unsatisfactory compaction effect, the width of the part of the flow guide spiral groove 20 close to the outlet of the extrusion head 10 is gradually reduced, and the discharge speed of the molten material is controlled.
The side wall of the extrusion cavity 11 is provided with a heating wire 21 spirally wound in the extrusion head 10, and the density of the heating wire 21 is gradually reduced along the direction close to the outlet of the extrusion head 10.
