The present invention provides an automatic sensing bundle elastic mechanism of a lotus buncher, which mainly comprises a lotus seat, an automatic wrapping and winding mechanism, a control unit, an automatic elastic control unit and a pressure by including a base. The touch sensing elements are oppositely configured； thereby, when each of the cymbals covers the cloth package, the outer diameter of the appropriate elastic coating of the actual circumferential surface of the cloth package can be automatically sensed, and the appropriate elastic covering outer diameter data is transmitted. Up to the automatic elastic control unit, when the cloth bag is tightened, the defect of the outer portion of the outer surface of the slab is not covered, so as to provide proper tightening pressure on the tea in the wrapped state. Can be more sturdy, in order to facilitate the subsequent ballast operations to make the tea a better ball state.本創作是提供一種蓮花束包機之自動感測束包鬆緊機構，主要是藉由包括一基座設置一蓮花座、一自動裹布成捲機構、一控制單元、一自動鬆緊控制單元及一壓觸感測元件所相對構成；藉此當各該揉捻片包覆布包時可自動感測該布包之實際環周面的適當鬆緊包覆外徑，並將適當鬆緊包覆外徑數據傳輸至該自動鬆緊控制單元，當束緊該布包時，不會令揉捻片未包覆布包位置產生部份凸出於外周的弊端，以提供適當的束緊壓力於該裹布狀態的茶葉能被揉捻地更夯實，以利於後續的團揉作業令茶葉呈現較佳的圓球狀態者。
