Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf re-drying processing technology, and more specifically, to a tobacco leaf mixing bin. Background Technology

[0002] In the tobacco leaf processing stage, uniformity of mixing plays a crucial role in product quality. Current tobacco leaf mixing processes still have some shortcomings. The leaf layout and mixing methods are relatively crude, potentially resulting in uneven initial conditions of the tobacco leaves entering the mixing area. Furthermore, differences in leaf size can easily lead to stratification during mixing, and localized accumulation and mixing dead zones can easily occur, further exacerbating the problem of insufficient uniformity. This results in differences in chemical composition and physical properties within the same batch of tobacco leaves, affecting the consistency and stability of the taste in subsequent cigarette products.

[0003] Therefore, there is an urgent need for a tobacco mixing chamber. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco flake mixing chamber to solve the problems in the prior art. It can drive the tobacco flakes to achieve full contact and mixing through multi-layer mixing discs, thereby improving the homogenization level of tobacco raw materials.

When a specific component is described as connecting to other components, the specific component may be directly connected to the other components without having an intermediary component, or it may not be directly connected to the other components but may have an intermediary component.

[0024] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0026] like Figures 1-3As shown, the tobacco mixing chamber provided in this embodiment includes: a mixing chamber body 1, a feed inlet 2 at the top of the mixing chamber body 1, a discharge outlet 11 at the lower end of one side wall of the mixing chamber body 1, and a plurality of rotatable mixing discs arranged from top to bottom inside the mixing chamber body 1, wherein the lowermost mixing disc corresponds to the position of the discharge outlet 11.

[0027] Among them, the diameters of the multiple mixing disks increase sequentially from top to bottom.

[0028] Furthermore, each of the mixing discs is circular in shape, and the rotation speed and / or direction of each mixing disc can be adjusted independently. In specific implementation, the parameters of each mixing disc can be selected according to the characteristics of the tobacco material and the complexity of the mixing.

[0029] During operation, tobacco leaf material falls into the mixing chamber body 1 through the feed inlet 2. Under the rotation of multiple mixing discs, the tobacco leaf material undergoes complex convective diffusion motion and is mixed multiple times through multi-stage mixing discs to achieve full contact and mixing, thereby improving the homogenization level of tobacco leaf raw materials processed online.

[0030] In one embodiment of this utility model, there are two mixing discs, namely an upper mixing disc 3 and a lower mixing disc 6 arranged from top to bottom. Specifically, an upper drive shaft 4 is vertically arranged at the middle position below the top of the mixing chamber body 1, and the upper mixing disc 3 is sleeved on the upper drive shaft 4. The upper drive shaft 4 is connected to an upper drive mechanism 5, which drives the upper mixing disc 3 to rotate through the upper drive shaft 4. A lower drive shaft 7 is vertically arranged at the middle position of the bottom of the mixing chamber body 1, and the lower mixing disc 6 is sleeved on the lower drive shaft 7. The lower drive shaft 7 is connected to a lower drive mechanism 8, which drives the lower mixing disc 6 to rotate through the lower drive shaft 7. The movement trajectory of the tobacco leaves is as follows: the tobacco leaves first fall into the upper mixing disc 3 in the mixing chamber body 1 through the feed inlet 2, where they undergo initial mixing. Under the centrifugal force generated by the rotational motion, the tobacco leaves fall into the lower mixing disc 6 through the gap between the edge of the upper mixing disc 3 and the inner wall of the mixing chamber body 1, where they undergo secondary mixing. The mixing process for three or more layers is similar and will not be described in detail here.

[0031] Furthermore, the diameter ratio of the lower mixing disk 6 to the upper mixing disk 3 is 1.5-2:1, for example, 1.8:1. It should be noted that this invention does not specifically limit the number, distribution, driving method, or size of the mixing disks.

[0032] Furthermore, each of the mixing discs is provided with a plurality of S-shaped guide plates 12 and a plurality of raised structures 13. The S-shaped guide plates 12 can guide the material to continuously change its trajectory based on the circular motion generated by the rotation, increasing the complexity of the motion and maximizing the contact opportunities of the material at different positions on the mixing disc; the raised structures 13 can loosen the tobacco flakes under the action of rotation and vibration of the mixing disc.

[0033] Furthermore, an air-jet auxiliary device 9 is provided on the inner side wall of the mixing chamber body 1. The air-jet auxiliary device 9 is connected to a blower 10. Driven by the blower 10, the air-jet auxiliary device 9 sprays air onto the material on the opposite side, controlling the discharge through airflow and driving the material to move and exit the chamber. The air-jet auxiliary device 9 and the discharge port 11 are arranged opposite each other. Specifically, the air-jet auxiliary device 9 includes an air pipe arranged vertically on the inner wall of the mixing chamber body 1 and multiple air jet holes formed on the air pipe.

[0034] The tobacco flake mixing chamber provided in this embodiment of the invention improves the homogenization level of the processed tobacco raw materials by setting multiple rotating mixing discs inside the mixing chamber body and performing multiple mixing processes through multiple layers of mixing discs. The S-shaped guide plate guides the material to continuously change its trajectory based on the circular motion generated by the rotation, increasing the complexity of the motion and maximizing the contact opportunities of the material at different positions on the mixing disc. The raised structure can loosen the tobacco flakes under the action of rotation and vibration of the mixing disc. The air jet auxiliary device drives the material to move and exit the chamber.

[0035] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
