[0006] A plurality of ventilation holes are formed on the first clamping plate and the second clamping plate.

[0007] The side of the first clamping plate and the second clamping plate is also connected with the mounting table, and the mounting table is fixedly provided with the foot pad.

[0008] The utility model has the advantages of:

[0009] Compared with the prior art, the stem tobacco leaf baking clamping device can adapt to tobacco stems with different diameters through the lower-narrow and upper-wide circular table-shaped clamping hole structure, and can guarantee clamping stability through flexible clamping of the end elastic rubber clamping piece, so that the stem tobacco leaf is effectively prevented from falling off after water loss in the baking process. The cross arrangement of the leaf clamping needles can effectively fix the base of the tobacco leaf between the clamping plates, and the double fixing action of the clamping hole can keep the tobacco leaf and the stem in a natural connection state, so as to ensure the quality of the baked tobacco leaf. Meanwhile, the locking mechanism composed of the spring clamping block and the locking buckle can realize quick opening and closing operation, and has a self-locking function to prevent accidental loosening during the baking process.

[0017] The technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0018] Embodiment 1

[0019] In order to solve the problem that the existing tobacco leaf baking clamp mainly clamps tobacco leaves, lacks clamping and fixing of stems, and the stem tobacco leaf is easy to fall off after water loss in the baking process, thereby causing the decline of the baking quality of the tobacco leaf. Referring to Figures 1 to 4As shown, the stem tobacco leaf roasting clamping device in the embodiment mainly comprises a first clamping plate 1 and a second clamping plate 2, the first clamping plate 1 and the second clamping plate 2 are symmetrically designed rectangular plate bodies, and a plurality of clamping holes 3 are correspondingly arranged on the opposite inner sides of the two plate bodies. When the first clamping plate 1 and the second clamping plate 2 are combined, the corresponding clamping holes 3 form a circular table-shaped channel with a narrow lower part and a wide upper part, which is used for wrapping the tobacco stem. The end of the clamping hole 3 extends out of a flexible rubber clamping piece 301, which is annular in structure and can provide flexible contact when clamping the stem to avoid crushing the surface tissue of the stem while adaptively clamping. A plurality of rows of clamping leaf needles 4 are arranged on the inner sides of the clamping plates below the clamping holes 3, and the clamping leaf needles 4 of the first clamping plate 1 and the clamping leaf needles 4 of the second clamping plate 2 are staggered and distributed, and form a cross fixed structure when combined, which is used for penetrating and locking the base leaf of the tobacco leaf.

[0020] The two ends of the first clamping plate 1 and the second clamping plate 2 are connected through a locking mechanism 5. The locking mechanism 5 comprises a spring clamping block 501 fixed to the side edge of the first clamping plate 1 and a locking buckle 502 installed on the side surface of the second clamping plate 2. The spring clamping block 501 is internally provided with a compression spring, and the front end thereof is a retractable hook structure capable of being buckled with the clamping groove of the locking buckle 502. When in operation, the first clamping plate 1 and the second clamping plate 2 can be quickly opened and closed by pressing the spring clamping block 501, and after being released, the hook structure automatically rebounds to lock, thereby ensuring that the clamping device is stably closed during the roasting process.

[0021] A plurality of ventilation holes 101 are uniformly arranged on the plate bodies of the first clamping plate 1 and the second clamping plate 2, the ventilation holes 101 penetrate the thickness direction of the clamping plate, form an air flow channel during roasting, promote the air flow around the tobacco leaf, and avoid excessive local humidity. In addition, the side surfaces of the first clamping plate 1 and the second clamping plate 2 respectively extend out of a mounting table 6, the mounting table 6 is located outside the clamping plate, and a foot pad 601 is fixed to the bottom of the mounting table 6, which is used for supporting the clamping device during the roasting process to prevent the clamping plate from directly contacting the high-temperature roasting rack.

[0022] In use, the stem of the tobacco leaf with stem is placed in the clamping hole 3 of the first clamping plate 1, the first clamping plate 1 and the second clamping plate 2 are combined, the lower end of the stem passes through the circular table-shaped channel and is clamped by the flexible rubber clamping piece 301, and the base leaf of the tobacco leaf is fixed by the cross clamping leaf needles 4. The clamping device is supported on the roasting rack by the foot pad 601, and the tobacco leaf is uniformly heated under the action of the air flow of the ventilation holes 101. The device ensures the clamping stability through the double clamping structure, and significantly reduces the phenomenon of tobacco leaf with stem falling off during the roasting process.

[0023] The preferred embodiments disclosed above are only used to help describe the utility model. The preferred embodiments do not describe all the details and limit the utility model to the specific embodiments described. Obviously, according to the content of the specification, many modifications and changes can be made.
