Novel once split cutting wheel device for rolling and connecting unit

The utility model discloses a new type one-time cutting wheel device for tobacco machine which comprises two floating threads on the two sides and a wheel body of cutting wheel comprising an internal drum wheel and an external drum wheel. The utility model is characterized in that an internal eccentric sleeve, an external eccentric sleeve, internal sleeves of the two floating threads and two rolling bearings are comprised. The internal eccentric sleeve is sleeved on the transmission shaft on the inside of the internal drum wheel and is fixed with an internal positioning flange frame by bolts. The external eccentric sleeve is sleeved on the external drum wheel and is fixed with an external positioning flange frame by screws. The two rolling bearings are sleeved on the internal eccentric sleeve and the external eccentric sleeve respectively and the internal sleeves of the floating threads are provided between the rolling bearings and the floating threads. The internal sleeves of the floating threads are connected with the floating threads by thread. Using the design, the floating threads are uniformly forced, operated stably, convenient for maintennance and the life service is improved. The shortages of the existing technology of floating threads deformation, unstable operation, influence on cigarette quality, etc are overcomed.
