| 摘要: |
| 目的 为了研究毛巾在给定包装尺寸参数条件下，如何保证毛巾包装严实、无褶皱的优良效果，对包装机的推杆推力等参数进行计算。方法 通过对毛巾压缩量和压缩受力进行试验分析，得出毛巾变形量与压缩受力之间的关系；对毛巾推入过程中负压吸附薄膜进行模拟仿真，得出吸附压强。将薄膜裹膜运动过程进行受力分解，分析牵引力对毛巾的影响，并计算出最优推力。结果 对负压入口压强进行了优化分析，确定负压为0.05 MPa。同时因毛巾柔软特性，对毛巾推动推力进行了优化分析，试验表明，毛巾垛要求高度在10～12 cm之间时，选择推力70.76 N；高度在12～20 cm之间时，选择推力为58.36 N。结论 根据计算所得，在以上推力下可保证薄膜的张紧，确保毛巾包装无褶皱情况，保证了包装效果，提高了包装效率。 |

| Abstract: |
| The work aims to study how to ensure the fine effect of towel packing without wrinkle under the given size parameter of towel so as to calculatethe thrust of push rod of packing machine. The relationship between the deformation of towel and the compression force wasobtained by analyzing the compression capacity and compression force of towels, and the adsorption pressure wasobtained by simulating the negative pressure adsorption film when the towel was pushed in. The effect of traction force on towels wasanalyzed and the optimal thrust wascalculated by decomposing the motion process of the wrapped film.The negative pressure inlet pressure was optimized and the negative pressure was determined to be 0.05 MPa. At the same time, due to the soft characteristics of the towel, the thrust of the towel wasoptimized. When the height of the towelswasbetween 10 cm and 12 cm, thrust of 70.76 N was selected. When the height wasbetween 12 cm and 20 cm, thrust of 70.76 N was chosen. According to the calculation, under the above thrust, the tension of the film can be ensured and the towel package is free from wrinkles, thus ensuring the packaging effect and improving the packaging efficiency. |
