摘要:为了延长精练机网带使用寿命、确保稳定运行,介绍粘胶短纤维后处理的必要性、精练机及网带的结构与作用;详细分析网带损坏的原因,提出具体解决措施。指出:网带所受拉力、网带圈丝直径、圈距及穿条直径、辊体直径与网带节距、网带材料、结构件变形、摩擦条材质、调偏以及网带运行速度均会影响网带的使用效果和寿命;设计时应合理确定网带圈丝直径、圈距及换向辊直径,保证结构件刚度;安装应保证辊体间的平行度及网托架、摩擦条的水平度;生产应根据产量合理匹配网速及丝层厚度以及传动辊、压辊、托辊的线速度,使网带受力均匀、运行平稳。

Abstract:In order to prolong the service life and ensure stable operation of the mesh belt of scouring machine,the necessity of post-treatment of viscose staple fiber and the structure and function of the scouring machine and the mesh belt are introduced.Detailed analysis is done to the damage causes of mesh belt,and the solutions are put forward.It is pointed out that the tension of mesh belt,the wire diameter of mesh belt,the wire distance and the threading diameter,the diameter of the roller and the pitch of mesh belt,the material of mesh belt,the deformation of the structural parts,the material of the friction strip,the deviation adjustment and the operation speed of mesh belt will affect the service effect and service life of the mesh belt.During the designing process,the wire diameter of mesh belt,the wire distance and the diameter of the reversing roller should be reasonably determined to ensure the rigidity of the structural parts.During the installation process,the parallelism between rollers and the levelness of mesh bracket and friction strip should be ensured.During the production process,the mesh speed,the thickness of the silk layer and the linear speed of the driving roller,the pressing roller and the supporting roller should be reasonably matched according to the output to make the mesh belt bear uniform stress and operating steadily.
Key Words:viscose staple fiber;scouring machine;mesh belt;threading;driving roller;reversing roller;friction strip;deformation;rigidity
