| 目的 研究高填充木塑复合材料在线挤出模压成型包装盒过程中，采用全自动计量装置计量的可行性，以及影响精度的因素。方法 采用自制的全自动木塑复合包装材料在线挤出计量装置，对不同材料配方复合材料在不同挤出机转速及熔体温度条件下进行评估，并计算计量误差。结果 随着木塑料复合包装材料中植物纤维含量的增加，计量稳定性变差，精度降低；相同配方条件下，挤出机的最佳挤出转速为200 r/min；熔体温度为190 ℃时，计量效果最佳。结论 采用自制的在线挤出计量装置对高填充木塑复合包装材料进行计量是可行的，复合材料的配方、挤出机转速和加工温度都会直接、间接地影响计量精度，对特定配方通过改变工艺参数可以得到最佳的计量精度。 |

| The work aims to study the measurement feasibility of automatic measurement setup in the process of online extrusion compression molding of packaging boxes with highly filled wood plastic composite as well as the factors influencing the accuracy. The composites made of different materials were evaluated at different extruder speeds and melt temperatures by the self-made online extrusion measurement setup for the automatic wood plastic packaging composites, and the measurement error was calculated. With the increase of plant fiber content in the wood plastic packaging composites, the measurement stability became poor and the measurement accuracy decreased. Under the same formula, the best extrusion speed of the extruder was 200 r/min. When the melt temperature was 190 ℃, the measurement effect was the best. It is feasible to measure the highly filled wood plastic packaging composites with the self-made online extrusion measurement setup. The formula, extruder speed and processing temperature of the composites will directly and indirectly affect the measurement accuracy. By changing the technological parameters of specific formula, the best measurement accuracy can be obtained. |
