Background
In the prior art, the tobacco leaf feeding method generally feeds the tobacco leaf into a feeding roller, then utilizes a two-fluid nozzle to atomize feed liquid under the action of compressed air, the feed liquid is applied to the upper surface of the tobacco leaf according to a certain proportion through a metering pump, and the fed tobacco leaf is overturned in the roller to gradually enable the feed liquid to permeate and absorb.
The tobacco leaf charging in the prior art has the following problems: 1. a large amount of tobacco leaves are turned in the roller to cause tobacco leaves to be overlapped, feed liquid can only be sprayed on the surfaces of the tobacco leaves, part of the tobacco leaves are not fed, and part of the tobacco leaves are fed more, so that uneven feeding is caused; the quality of the cigarette product fluctuates, and the sensory quality of the cigarette is influenced. 2. Because two fluid nozzles are used, a large amount of compressed air is sprayed into the roller, moisture removal treatment is needed to be carried out in order to maintain the micro negative pressure state in the roller, and micro atomized feed liquid particles which are not absorbed by tobacco leaves in the roller are discharged out of the roller along with a moisture removal system, so that the actual feeding proportion is far lower than the theoretical feeding proportion, and feed liquid is wasted; and simultaneously pollutes the ambient air. 3.
