| Abstract: |
| Adhesive tape is commonly used in packaging industry. For a new tape packaging mechanism, the winding and packaging process of flexible plastic bag using adhesive tape was analyzed. A mechanical model of tape peeling was established based on fracture energy release mechanism and by introduction of fracture mechanics concept. The relationship between tape peeling speed and peeling force was studied and the minimum driving force of winding packaging was obtained. In order to realize packaging of plastic bag under the minimum driving force, the position of spring pedestal was optimized. |
| Key words: adhesive tape spring pedestal minimum driving force peeling force optimize |
