Firstly, the right installation positioning hole is moved rightwards to extend the distance of the separation zone. Meanwhile, the vibration mechanism is redesigned so that it is enabled to move toward the lower right of the material groove body. Therefore, there is enough space to install the separation screen in the separation zone. Finally, the separation screen is installed. The tobacco scraps are separated out when they pass through the separation screen, thus reducing cone dropping when the cigarette burns, stabilizing the amount of dropping tobacco at the end, and improving the smoking experience and recognition of customers with regard to cigarette products.
