the invention firstly utilizes the end cam to realize the separation of the left separation block and the right separation block, so that the cigarette on the separation block is firstly separated by a short distance; then utilize the air current to make cigarette for the motion of separation piece under the state that utilizes the cage to keep apart separating wheel and periphery, make cigarette separate a longer distance again to can realize the long distance separation of cigarette. The separating wheel is separated from the periphery by the isolating cover, so that the cigarette can be driven by airflow, peripheral dust and scattered cigarettes and filter tips can be prevented from being sucked, and the pollution of equipment in the separating process of the cigarettes is avoided.
The cigarette long-distance separation can be realized (for example, 40-60mm) only by moving the separation block for a short distance (for example, 6mm, so as to effectively prevent the cigarettes and the filters from entering), and the cigarette long-distance separation can be realized by short-distance mechanical movement, so that the suction phenomenon of the cigarettes, the filters and dust during the long-distance and quick separation of the separation block can be avoided.
The long-distance separation of the cigarettes does not need to depend on the long-distance movement of the separation block, so that the structure of the moving mechanism of the separation block can be simplified, and a complex moving mechanism is not needed.
The invention can adapt to the length of cigarettes in a larger range, and if the length of the cigarettes changes, the invention can adapt to the cigarettes with different lengths only by adjusting the positions of the left and/or right cigarette positioning stop blocks along the axial direction.
