Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packing, in particular to a box opening blocking structure of a tobacco packing device. Background Art

[0002] In tobacco production, with the development of the times, in order to improve production efficiency, tobacco leaves are mostly packed on production lines. Generally, large quantities of tobacco leaves are transported through production lines. The tobacco leaves are fed from the upper port through a guide barrel and fall into the carton from the lower port to realize tobacco packing. However, when the tobacco leaves fall from the upper end of the guide barrel into the carton at the lower end, airflow will be generated, causing the tobacco leaves to spray out from the box opening of the carton. In the prior art, a sealing strip is generally used to seal the box opening, but this will cause the air pressure between the outer wall of the guide barrel and the inner wall of the carton to be too high, which will still cause the tobacco leaves to spray out from the box opening of the carton.
