| 目的 探寻纸盒模切压痕时，盒片模切压痕形态与模切力以及折叠纸盒成型质量之间的相互关联关系，从而对纸盒模切力进行有效标准控制，并最终提高纸盒成型质量及其稳定性。方法 采用三维激光扫描仪对纸盒进行非接触式扫描获得高精度的压痕线扫描点云，在此基础上利用特定算法把压痕线从无序点云中提取出来，随后对测量数据进行分析和计算，分别计算出压痕线的深度和宽度。结果 结果表明采用三维激光扫描技术有效地测量了纸盒压痕深度和压痕宽度等一系列数据。所获得的测试数据与理论计算数据的误差值极小，平均误差在0.01 mm左右，证明了该测量方法的有效性、可靠性及精准性。此外，为了研究硬盒盒片压痕形态与压痕挺度之间的相互关系，并建立较为准确的函数关系模型，也利用该仪器进行了大量测试工作并对测试数据进行了统计分析及曲线拟合，所获得的结果与理论分析高度一致。结论 压痕形态的有效测量以及压痕形态与压痕挺度之间关系模型的建立为纸盒模切质量的有效控制提供了理论基础和数据依据。 |

| The work aims to explore the interrelation among indentation shape, cutting force and forming quality of folding carton when carton die is cut and pressed, in order to effectively control the cutting force of carton and ultimately improve the forming quality and stability of carton. Three-dimensional laser scanner was used to conduct non-contact scanning on the carton to obtain a high-precision indentation line scanning point cloud. On this basis, a specific algorithm was used to extract the indentation line from the unordered point cloud, and then the measured data were analyzed and calculated to get the depth and width of the indentation line, respectively. A series of data such as indentation depth and width of carton were effectively measured by three-dimensional laser scanning technology. The error between the obtained test data and the theoretical calculation data was very small, and the average error was about 0.01 mm, which proved the effectiveness, reliability and accuracy of the measurement method. In addition, in order to study the interrelation between the indentation shape and the indentation stiffness of the hard carton and establish a more accurate functional interrelationship model, a lot of test work was carried out with this instrument, and statistical analysis and curve fitting were conducted on the test data. The results obtained were highly consistent with the theoretical analysis. The effective measurement of indentation shape and the establishment of the interrelationship model between indentation shape and indentation stiffness provide theoretical basis and data basis for the effective control of carton die cutting quality. |
