摘要
文章通过运用谢宁方法的变量搜索试验,对影响卷接机空头率的关键因子进行分析验证及确定,量化其影响程度及主效应和交互效应的关系,并在此基础上对关键因子进行优化试验和生产跟踪验证,降低卷接机的空头率。变量搜索试验结果表明,卷接机针辊转速、风室负压的主效应大于交换效应,且主效应大于其他因子,是影响卷接机空头率的关键因子。因子优化试验结果表明,针辊转速对卷接机空头率的影响为二次函数关系,当针辊转速在1680 mv时,空头率为0.278%;风室负压对卷接机空头率的影响为一次函数关系,当风室负压为-112×10^(2)Pa时,空头率为0.188%。经生产跟踪验证结果表明,在针辊转速为1650 mv~1700 mv,风室负压为-108×10^(2)Pa~-110×10^(2)Pa的条件下,卷接机空头率降为0.20%、降幅50%。
By using the variable search test of Shainin method, this paper analyzes, verifies and determines the key factors affecting the short position rate of the coiler, quantifies its influence degree and the relationship between the main effect and the interaction effect,and on this basis, carries out the optimization test and production tracking verification on the key factors to reduce the cigarette machine loose-end rate. The results of variable search test show that the main effect of needle roller speed and negative pressure in air chamber of coiler is greater than exchange effect, and the main effect is greater than other factors, which is the key factor affecting the cigarette machine loose-end rate. The results of factor optimization test show that the influence of needle roller speed on the cigarette machine loose-end rate is a quadratic function relationship. When the needle roller speed is 1680 mv, the cigarette machine loose-end rate is 0.278%;the effect of negative pressure in the air chamber on the cigarette machine loose-end rate is linear function relationship, when the negative pressure in the air chamber is -112×10^(2) Pa, the cigarette machine loose-end rate is 0.188%. The production tracking verification results show that when the speed of needle roller is 1650 mv ~ 1700 mv, the negative pressure of air chamber is -108×10^(2) Pa~-110×10^(2) Pa, the cigarette machine loose-end rate is reduced to 0.20%, and the decrease range is 50%.
