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.
