Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing, and in particular to a feeding device. Background Art

[0002] As a new tobacco product, heated cigarettes are gaining consumer acceptance due to their advantages, such as harm reduction and a variety of flavors, leading to a growing market. As low-temperature cigarettes, heated cigarettes primarily use heat to steam the smoking material, releasing a large amount of inhalable aerosol at low temperatures. This delivers a similar feeling of satisfaction to cigarettes while reducing the production of harmful substances.

[0003] The current method for stabilizing and controlling aerosol release primarily involves adding a smoking agent, primarily glycerin, to the smoking material while simultaneously reducing its moisture content. For heated cigarettes made primarily of tobacco flakes, glycerin can be added by coating, while non-flake tobacco materials are typically added by roller dosing. However, due to glycerin's viscous and poor fluidity, the roller dosing process can easily lead to tobacco material sticking, uneven glycerin addition, poor absorption, and significant glycerin loss, compromising cigarette quality and causing waste.

The telescopic support member 73 is driven to rotate the upper support 71 relative to the lower support 72 by a certain angle, thereby driving the pitch angle adjustment of the drum 4, which is positioned on the upper support 71 and has a certain clearance from the ground. The open end of the drum 4 faces away from the hinge axis, i.e., the pitch direction of the drum 4 is perpendicular to its rotation axis. Therefore, during feeding, the drum 4 can be raised by a certain angle (e.g., an angle of 3-5° from the horizontal plane) to facilitate the entry of tobacco raw materials into the depth of the drum 4. During discharging, the drum 4 can be lowered by a certain angle to allow the added tobacco raw materials to slide to the opening for easy discharge.

[0107] At the same time, the drum drive assembly 5 and the drum heating assembly 6 are both arranged on the upper bracket 71 and can rotate with the upper bracket 71 without affecting their connection with the drum 4.

[0108] The support telescopic member 73 can use a power element known in the art, such as a motor or a hydraulic cylinder. More preferably, the end of the support telescopic member 73 connected to the upper support 71 or the lower support 72 is slidable to prevent the roller 4 from being "stuck" during the pitch adjustment process. Sliding can be achieved using a slider rail.

[0115] A third filter 83 may also be provided on the recovery pipeline for filtering, thereby making the material recovered in the recovery tank 82 purer. More preferably, the liquid supply assembly 2 is provided with a first weight sensor 25, and the recovery tank 82 is provided with a second weight sensor 84. The control module receives signals from the first weight sensor 25 and the second weight sensor 84, and by comparing weight changes, can determine the actual amount of atomizer added and adjust the operation of the gas supply assembly 1 and the liquid supply assembly 2 as needed to reduce atomizer waste.

[0116] Specifically, let Q1 represent the total amount of atomizer added. Not all of the atomizer will be absorbed. Meanwhile, let Q2 represent the increase in the weight of the recovery tank 82, representing the unabsorbed atomizer. Set the required atomizer dosage Q based on the actual atomized weight. When Q1 - Q2 = Q, the required dosage has been achieved, and the spray assembly is turned off.
