Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco screening and cutting production, and in particular relates to tobacco screening and cutting equipment. Background Art

[0002] The heating and humidification process in the tobacco processing is to heat and humidify the cut tobacco leaves and make them fully moist. After the temperature and moisture content of the tobacco leaves reach certain requirements, they are dried in the drying tube of the continuous airflow drying process and the drum of the thin plate drying process to improve the filling capacity of the tobacco leaves. As one of the key links in tobacco processing, the heating and humidification equipment plays a very important role.

[0003] The existing tobacco cutting equipment has poor cutting effect. There are still many long tobacco shreds after cutting, which affects the subsequent processing and production. In addition, the screen plate in the existing tobacco cutting equipment is not easy to disassemble. When the screen plate is blocked, it cannot be cleaned conveniently, and the practicality is not high. Therefore, it is necessary to propose improvements. Utility Model Content
