[0002] According to statistics, tobacco processing needs to go through multiple processes, one of which is to weave fresh tobacco leaves to facilitate air drying and avoid rotting due to moisture when stacked together. The traditional method of weaving tobacco leaves is to manually use a rope to tie the leaf stalks of the tobacco leaves with the leaf tips facing down. This method is suitable for small-scale tobacco weaving and drying, and traditional manual tobacco weaving is time-consuming and labor-intensive. Moreover, it is inconvenient to remove the tobacco leaves. For farmers or bases with large areas of cultivation, if the tobacco leaves cannot be woven and dried within a short period of time, the unweaved and dried tobacco leaves will rot and deteriorate, affecting the quality of tobacco production. Therefore, how to improve the efficiency and quality of tobacco weaving is a problem that large-scale tobacco cultivation bases have been studying. SUMMARY
