Device for forming a multi-flavor composite structure filter rod in one step and a method thereof using the device

A device for forming a multi-flavor composite structure filter rod in one step, comprising:

• a tow transmission belt, a tow guiding horn-shaped mouth, a tow assembly paper collection groove, a cigarette lap adhesive applying device, multi-flavor adding devices adding flavors to the filter rod, a locating and identifying device and a locating and cutting device downstream of the tow assembly paper collection groove, a locating and identifying probe on the locating and identifying device, and a control device electrically connected to the tow transmission belt, the multi-flavor adding devices, the tow guiding horn-shaped mouth, the tow assembly paper collection groove, the cigarette lap adhesive applying device, the locating and identifying device, and the locating and cutting device;
• wherein the multi-flavor adding devices are arranged in different sections to obtain one-step formation of the multi-flavor composite structure filter rods;
• the flavors comprise granular flavors, gel flavors and bead flavors;
• the tow guiding horn-shaped mouth is upstream of the tow assembly paper collection groove;
• the tow transmission belt enters from a larger opening of the tow guiding horn-shaped mouth into the tow guiding horn-shaped mouth and comes out from a smaller opening of the tow guiding horn-shaped mouth, which is close to an inlet opening of the tow assembly paper collection groove;
• forming paper enters from an inlet opening of the tow assembly paper collection groove;
• a granular flavor adding device is configured upstream of the tow guiding horn-shaped mouth, and the larger opening of the tow guiding horn-shaped mouth faces the granular flavor adding device;
• a gel flavor adding device is at the smaller opening of the tow guiding horn-shaped mouth;
• a bead flavor adding device is close to the inlet opening of the tow assembly paper collection groove;
• and the cigarette lap adhesive applying device is close to an outlet opening of the tow assembly paper collection groove.
