1、青岛大学毕业论文 - i - 摘要 包装是商品进入流通的前提，包装机械是实现包装的重要手段。包装机械大大降低了劳动强度，改善劳动条件，提高了加工效率。 瓦楞纸板生产线是纸箱包装 机械 中最重要的生产线设备 。 纵切压痕机是瓦楞纸板生产线的重要组成部分，它的性能直接关系到瓦楞纸板生产线的生产效率和质量。 切纸部分 是纵切压痕机的 重要部分 ，它们的结构对整机的设计和工作时的稳定性有很大的影响。 在借鉴以有设计的基础上，对 切纸部分 进行改进设计 ，从而提高纵切压痕机的工作效率和使用寿命 。 关键词：包装机械 瓦楞纸板生产线 纵切压痕机 切纸部分 青岛大学毕业论文 - ii - Abstract
2、The packing machinery is an important method to realize packing, which is the premise for the commodity to enter the circulation. The packing machinery reduces the labor intensity greatly, improves work condition, and enhances the processing efficiency. The corrugated cardboard production line is eq
3、uipment in the paper box packing machinery, and the longitudinal cutting and creasing machine, performance of which affects the production efficiency and the quality of the corrugated cardboard production line, is an important part of the corrugated cardboard production line. The cutting module is a
4、 important part of the longitudinal indentation machine, its structure makes very tremendous influence to the design of the entire machine, and the work stability. By referring to designs existed, some improvement should be done to the cutting module, thus enhances efficiency and the service life of the longitudinal cutting and creasing machine Keywords: The packing machinery The corrugated cardboard production line The longitudinal cutting and creasing machine The cutting module
