一种用于纺粘非织造布、化纤的新型挤压机螺杆
摘要：
本实用新型属于纺织机械技术领域，涉及一种用于生产纺粘非织造布、化纤的新型挤压机的螺杆。包括进料段、压缩段和计量段，在压缩段上的主螺纹之间设有起始段是封闭的副螺纹，进料段的长度L1＝8～12D1，压缩段的长度L2＝8～10D1，计量段的长度L3＝8～10D1，螺杆的长径比L4/D1＝25～30D2，螺杆的总压缩比h1/h3＝2.9～3.4，副螺纹总长度L′＝(8～10)D2，副螺纹的总螺距S2＝95～220mm。在计量段的头部可增设混炼头。优点是：在压缩段可保证高聚物的固、液相完全分离而提高熔融速率、提高螺杆挤压机的挤出量。在混炼头作用下，将全部熔融的高聚物熔体充分均化；熔体的运动粘度趋近于均匀一致，与目前现有相同规格的螺杆相比，生产率提高18－38％；能耗降低10－15％。
摘要（英）：

The utility model belongs to the technical field of textile machine and relates to a novel extruder screw used for producing non woven fabric and chemical fiber, which comprises a feeding section, a compression section and a metering section. A sub-screw thread whose initial section is sealed is arranged between the main screw threads on the compression section. The length of the feeding section is L1 =8-12D1, and the length of the compression section is L2 =8-10D1, and the length of the metering section is L3 =8-10D1. The ratio of length to diameter of the screw is L4 /D1 =25-30D2, and the total compression ratio of the screw is h1 /h3 =2.9-3.4. The total length of the sub-screw thread is L'=(8-10) D2, and the total screw pitch of the sub-screw thread is S2 =95-220 mm. A mixing head can be added on the head end of the metering section. The utility model has the advantages that the complete separation of the solid and liquid high polymer is guaranteed, which improves the fusion speed and the extruding output of a screw extrusion press. Under the action of the mixing head, all the fused high polymer fuse elements are equalized, and the kinematical viscosity of the fuse element approaches to uniformity. Compared with the existing screw in same size, productivity is increased by 18-38%, and energy consumption is decreased by 10-15%.
