| 目的 为了改善软包装复合膜在生产过程中出现的复合皱折问题。方法 在现有薄膜收卷张力模型的基础上，对薄膜收卷的内张力进行分析，建立以卷径Ri=1.5R0为分界点的分段张力收卷模型。结果 按照该模型设置收卷张力可以很好地避免现有收卷张力模型存在的具有张力薄弱点和内部张力过大等问题，可以有效减小设备、材料等不稳定因素产生的影响，从而有效减少复合皱折问题。结论 利用这一优化的张力收卷模型，通过长期、大量的生产实践，统计出复合皱折损耗率从平均5%下降到低于1%，复合皱折问题得到明显的改善，给公司带来超过200万元/年的经济效益。 |
| 英文摘要: |
| The paper aims to relieve the wrinkle issue in production of flexible packaging laminating films. Based on the existing film winding tension model, the internal tension of composite film was analyzed; and a piecewise tension winding model with winding diameter Ri=1.5R0 as the cut-off point was established. Setting the winding tension according to the model can avoid the problems of the existing winding tension model, such as weak point of tension and excessive internal tension, and can effectively reduce the influence of unstable factors such as equipment and materials, to effectively reduce the wrinkling issue. By using the optimized tension winding model and through long-term and massive production practice, the loss rate of wrinkle is statistically reduced from 5% to <1%, which significantly relieves the wrinkle issue and brings the company more than 2 million yuan of annual economic benefits. |
