Description

Technical Field

[0001] This utility model belongs to the field of tobacco processing technology, specifically relating to a fresh tobacco leaf drying device. Background Technology

[0002] Curing is one of the key steps in tobacco processing, and curing barns are essential equipment for tobacco curing. With the promotion and application of modern tobacco agriculture, my country's tobacco curing equipment has undergone a development process from ordinary curing barns to standardized curing barns, and then to intensive curing barns. Currently, the main methods of loading tobacco into intensive curing barns in my country are loose leaf loading, tobacco clamping, and tobacco tying with tobacco stalks. The loading method significantly affects the economic characteristics of the cured tobacco leaves. Studies have shown that loose leaf intensive curing has the effects of reducing labor, lowering curing costs, improving tobacco quality, and increasing economic benefits.

[0003] Existing methods for loading loose tobacco leaves include loose leaf tack loading, loose leaf basket loading, loose leaf stacking, and box-type loose leaf loading. Loose leaf tack loading provides better ventilation, which is conducive to the uniform curing of tobacco leaves. However, during the loading process, because fresh tobacco leaves are relatively brittle, the tobacco stems are easily damaged when inserted into the bottom support. Other loading methods all have poor ventilation. During the curing process, the tobacco leaves may wilt due to water loss, which may cause the tobacco leaves to fall over and collapse, further affecting air permeability and moisture loss, thus leading to unsatisfactory curing results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a fresh tobacco leaf curing device, which improves ventilation during fresh tobacco leaf curing by changing the tobacco loading method, thereby increasing the tobacco leaf curing efficiency and optimizing the quality of the cured tobacco leaves.

[0005] This utility model discloses a fresh tobacco leaf drying device, comprising a movable base with casters at the bottom and slots evenly spaced inside the base. A fixing plate is inserted into each slot, and a first clamping cage is fixedly connected to the top of the fixing plate. A second clamping cage is connected to one end of the first clamping cage via a pivot. Both the first and second clamping cages are mesh-shaped, and their connection forms a tobacco-filling cage. A sliding groove is provided on one side of the fixing plate, with a spring-loaded block slidably connected inside. A limiting groove is provided on the other side of the fixing plate. A connecting plate is fixedly connected to one end of the second clamping cage, and a limiting block is fixedly connected to the bottom of the connecting plate. The limiting block is inserted into the limiting groove, and the spring-loaded block and the limiting block are positioned on the same central axis.

[0006] Multiple sets of limiting holes are opened on both sides of the inner wall of the movable base, and spring plates are provided on both sides of the outer wall of the movable base. A card plate is rotatably connected to the front end of the slot, and a fixed gear is fixedly connected to the center of one end of the card plate. The fixed gear and the fixed plate are meshed together. Spring buckles are fixed on both sides of one end of the fixed plate, and the spring buckles are engaged with the limiting holes.

[0007] The beneficial effects of this utility model are:

[0008] Compared with the prior art, the fresh tobacco leaf curing device of this utility model forms a tobacco loading cage through the connection structure of the first and second clamps. The tobacco leaves are laid flat in the tobacco loading cage and clamped and fixed. There is a distance between each tobacco loading cage, which can increase air permeability. The size of the clamps is fixed, which is conducive to standardized control of the amount and density of tobacco loaded. After the tobacco leaves lose water and wilt during the curing process, the wind direction in the curing barn can be changed so that the wind enters through the gaps in the tobacco leaves, thereby improving the problem of poor ventilation caused by the wilted, collapsed and folded tobacco leaves. After the tobacco leaves are fixed in the tobacco cage, the ventilation conditions are better, which can improve the internal quality of the cured tobacco leaves. The overall design is simple to operate and easy to handle and load. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Embodiment 1

[0019] To ensure the quality of dried tobacco leaves and prevent dampness and mold growth caused by stacking while quickly packing them, please refer to [reference needed]. Figures 1 to 6 As shown, the fresh tobacco curing device in this embodiment includes a movable base 1. The bottom of the movable base 1 is equipped with casters 16 to facilitate the transfer of the movable base to the curing barn. The movable base 1 has slots 2 evenly spaced inside, and a fixing plate 3 is inserted into the slots 2. A first clamping cage 4 is fixedly connected to the top of the fixing plate 3. A second clamping cage 5 is connected to one end of the first clamping cage 4 through a pivot. Both the first clamping cage 4 and the second clamping cage 5 are designed as mesh grids to reduce the material cost of the first clamping cage 4 and the second clamping cage 5 while improving air permeability. The connection of the first clamping cage and the second clamping cage forms a tobacco cage. A sliding groove 8 is provided on one side of the fixing plate 3, and a spring clip 9 is slidably connected inside the sliding groove 8. A limiting groove 6 is provided on the other side of the fixing plate 3. A connecting plate 7 is fixedly connected to one end of the second clamping cage 5, and a limiting block 10 is fixedly connected to the bottom end of the connecting plate 7. The limiting block 10 is inserted into the limiting groove 6. The spring clip 9 and the limiting block 10 are set on the same central axis.

[0020] Workers sequentially lay fresh tobacco leaves on top of the first clamping cage 4, while simultaneously rotating the second clamping cage 5 above the first clamping cage 4. This causes the connecting plate 7 installed at one end of the second clamping cage 5 to fit against the top of the fixing plate 3. By sliding the spring-loaded block 9 inside the sliding groove 8, the limiting block 10 is inserted into the limiting groove 6. Releasing the sliding of the spring-loaded block 9 allows it to reset and return one end to insert into the limiting block 10, thus limiting the movement of the second clamping cage 5 and the first clamping cage 4, thereby forming a complete assembly. The tobacco cages, with a distance between each cage, increase air permeability. The fixed size of the cages facilitates standardized control of the amount and density of tobacco loaded. During the curing process, after the tobacco leaves lose moisture and wilt, the wind direction in the curing barn can be changed, allowing air to enter through the gaps in the tobacco leaves. This improves the poor ventilation caused by the leaves collapsing and drooping. Using tobacco cages to fix the tobacco leaves before loading ensures better ventilation, improving the internal quality of the cured tobacco leaves. The overall design is simple to operate and easy to handle and load.

[0021] Specifically, the movable base 1 can be customized to different lengths according to the actual conditions of the baking room.

[0022] Multiple sets of limiting holes 11 are opened on both sides of the inner wall of the mobile base 1. Spring plates 13 are provided on both sides of the outer wall of the mobile base 1. A card plate 15 is rotatably connected to the front end of the slot 2. A fixed gear 14 is fixedly connected to the center of one end of the card plate 15. The fixed gear 14 and the fixed plate 3 are meshed and connected. Spring buckles 12 are fixed on both sides of one end of the fixed plate 3. The spring buckles 12 and the limiting holes 11 are engaged and connected.

[0023] Insert the fixing plate 3 into the slot 2, so that the spring clips 12 and the limiting holes 11 installed on both sides of one end of the fixing plate 3 are limited, and at the same time, the fixing plate 3 and the fixing gear 14 can be engaged and connected, and the clamping plate 15 at one end can be flipped horizontally and locked and limited. When unloading dry tobacco leaves, press the spring plates 13 on both sides of the moving base 1 to release the limiting installation formed between the connecting component and the limiting hole 11, and the fixing plate 3 can be removed.

[0024] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
