The processing effect of the link directly influences the internal quality of the cut tobacco. At present, tobacco leaf charging equipment is generally roller equipment, and a nozzle of the tobacco leaf charging equipment is generally arranged at the feeding end of the roller equipment. The nozzle is used as an important component of the roller equipment, the atomization effect and the adjustment angle of the nozzle play a direct role in determining the processing effect, the spraying quality directly influences the uniformity and the precision of feeding, and the uniformity and the precision of feeding determine the homogenization level of a product and the inherent quality of tobacco leaves. It is therefore necessary to check the nozzle angle frequently and to adjust it as necessary to ensure that the application medium is sprayed uniformly onto the material.

The tobacco leaf feeding nozzle is a double-medium nozzle, the cleaning period of the double-medium nozzle is one to two times per month, and the position of the nozzle needs to be recovered after cleaning. Because it is in the three-dimensional space position, an experienced operator is required to enter the interior of the drum to make trial adjustments each time the position is restored.
