                          摘要:為了提高直梳梳理機的梳綿質量,借鑒長麻紡工藝設計出適用于絹紡自動化系統的“平面針簾—副夾板—平面針簾”的新型絹紡直梳梳理工藝;設計直梳梳理機構,設定直梳梳理區4個針簾所用針布與梳針類型、針/齒密度、針簾與副夾板工作區長度以及梳針作用數、針簾梳理速度等主要參數;利用流體仿真軟件建立直梳梳理區“梳簾—梳針—空氣”模型,分析梳理速度對梳理區氣流的影響,確定針簾和梳針參數。指出:新型絹紡直梳工藝,A,B針簾選用彈性針布、低中速梳理,C,D針簾選用金屬針布、較高速梳理,結合合適的梳針密度以及梳針作用數,能減小梳綿損失、避免氣流紊亂,且不影響梳理效率,滿足直梳自動化和連續化的生產要求。

                          Abstract:In order to improve the draft combing quality of a straight carding machine,learning from the long linen spinning process,a new type of straight carding process of “plane needle curtain-auxiliary splint-plane needle curtain”,which is suitable for the automatic system of silk spinning is designed.In the process,a straight carding mechanism is designed,and the main parameters such as the card clothing and pin type for four plane needle curtain of straight combing area,the density of needle/tooth,the work area length of plane needle curtain and auxiliary splint,the action number of pin,and the carding speed of plane needle curtain.The “carding curtain-pin-air” model is established by using the fluid simulation software to analyze the influence of the carding speed on the air flow in the combing area and determine the parameters of the plane needle curtain and pin.It is pointed out that the new straight carding process for silk spinning,elastic card clothing and low and medium carding speed are used for A and B plane needle curtain,metal card clothing and high carding speed are used for C and D plane needle curtain,which can combine appropriate density and action number of pin to reduce the carding loss,avoid airflow disturbance,not affect the carding efficiency,and meet the requirements of automatic and continuous production of straight carding.
