Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to an online tobacco remixing device and an online tobacco remixing method. Background Art

[0002] In the production process of filter cigarettes, due to factors such as raw materials, equipment and operator quality, there will be problems such as insufficient fullness and tightness of tobacco, blurred work number printing, missing printing, color difference of tipping paper, air leakage at the interface, inconsistent suction resistance and packaging quality defects, thus forming a certain number of defective cigarettes. These defective cigarettes are not caused by tobacco quality problems, so the tobacco can be completely recycled. In the prior art, there are two main methods for recycling tobacco in cigarettes. One is to separate the tobacco from the cigarette by breaking the cigarette paper on the surface of the cigarette with water vapor. Since the tobacco is in contact with water and air, it is easy to change color, become broken and moldy, resulting in the degradation of tobacco and low efficiency of tobacco recycling. The other method is the air blowing recovery method. This method separates the tobacco from the outer packaging paper tube of the cigarette by blowing air into the outer packaging paper tube of the cigarette. For filter cigarettes, the airflow can only be separated in one direction, which affects the application range of the equipment.
