Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of drying equipment, specifically a tobacco processing drying device. Background Technology
[0002] Tobacco (scientific name: *Nicotiana tabacum* L.) is an annual herbaceous plant belonging to the genus *Nicotiana* in the family Solanaceae. Its leaves are oblong-lanceolate, lanceolate, oblong, or ovate, with an acuminate apex and a gradually narrowed base forming an auricle-like semi-amplexicaul shape. The petioles are inconspicuous or winged. The inflorescence is paniculate; the calyx is tubular or tubular-campanulate with triangular-lanceolate lobes; the corolla is funnel-shaped, pale yellow, pale green, red, or pink, with a yellowish base. The capsule is ovoid or elliptical, nearly as long as the persistent calyx; the seeds are round or broadly oblong, brown. Flowering and fruiting occur in summer and autumn.
[0003] During its processing, drying is required. An existing tobacco leaf drying device, such as the one with patent publication number CN222764772U, heats the air in the heating chamber through a heating plate in the heating chamber. An inlet fan draws air from the main chamber into the heating chamber for heating, and then an outlet fan discharges the hot air from the heating chamber into the main chamber, so that the hot air in the main chamber forms a circulating airflow, which makes the moisture of the tobacco leaves evenly removed.
[0004] However, the device is prone to tobacco leaf accumulation during use, resulting in low drying efficiency and insufficient practicality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example
[0025] Please see Figure 1-4A tobacco processing and drying device includes a base 1, a vertical frame 2, a hinge block 3, a hinge shaft 4, a hinge frame 5, a drying cylinder 6, a rotary drive motor 7, a synchronous shaft 8, an inner mesh cylinder 9, electric heating tubes 10, hinges 11, a front cover 12, and a sealing head 13. The top side of the base 1 is connected to the bottom side of the vertical frame 2, and the top side of the vertical frame 2 is connected to the bottom side of the hinge block 3. The outer side of the hinge block 3 is movably connected to the inner side of the hinge frame 5 via the hinge shaft 4. The top of the hinge frame 5 is connected to the bottom side of the drying cylinder 6. Multiple sets of electric heating tubes 10 are installed inside the drying cylinder 6. The rear side of the drying cylinder 6 is connected to the front side of the rotary drive motor 7. The output end of the rotary drive motor 7 is connected to the rear side of the inner mesh cylinder 9 via the synchronous shaft 8. The front left side of the drying cylinder 6 is movably connected to the right side of the front cover 12 via the hinge 11. A sealing head 13 is connected to the inner side of the front cover 12. A locking mechanism is provided between the constraint roller 16 and the vertical frame 2, and a support structure is provided between the vertical frame 2 and the drying cylinder 6. Tobacco to be dried can be placed in the inner mesh cylinder 9, so that the front cover 12 is closed on the front side of the drying cylinder 6 and locked by the locking mechanism. The front opening of the inner mesh cylinder 9 is blocked by the sealing head 13. During drying, the support structure provides auxiliary support to the drying cylinder 6. The rotary drive motor 7 runs and drives the inner mesh cylinder 9 to rotate via the synchronous shaft 8, so that the tobacco inside is constantly turned over. Under the heating action of the electric heating tube 10 inside the drying cylinder 6, it is evenly heated and dried quickly. After completion, the locking mechanism is unlocked, and the front cover 12 is opened under the constraint of the hinge 11, so that the front opening of the inner mesh cylinder 9 can be opened. Then, the support is released, and the drying cylinder 6 can be turned over by the hinge frame 5 and the hinge shaft 4 constrained to the outside of the hinge block 3, so that the front side of the drying cylinder 6 and the inner mesh cylinder 9 are downward together, thereby pouring out the tobacco.
[0026] It also includes a shaft frame 14, a roller shaft 15, and a constraint roller 16. Multiple sets of shaft frames 14 are evenly connected in a circumferential direction inside the front side of the drying cylinder 6. The inner side of the shaft frame 14 is rotatably connected to the outer side of the constraint roller 16 via the roller shaft 15. The constraint roller 16 rotates and contacts the outer wall of the inner mesh cylinder 9. When the inner mesh cylinder 9 rotates, it can be contacted by the constraint roller 16 and constrained by the inner roller shaft 15 of the shaft frame 14, thereby providing movable support to the front outer wall of the inner mesh cylinder 9, avoiding displacement and improving stability.
[0027] The locking mechanism includes a movable sleeve 17, a handle 18, a handle bar 19, a movable pin 20, and a fixed pin bracket 21. The movable sleeve 17 is connected to the left side of the front cover 12. The inner wall of the movable sleeve 17 is rotatably connected to the outer wall of the handle 18. The outer side of the handle 18 is connected to one side of the handle bar 19, and the inner side of the handle 18 is connected to one side of the movable pin 20. The fixed pin bracket 21 is connected to the right middle side of the front end of the drying cylinder 6. When the front cover 12 is closed, the handle bar 19 can be held to rotate the handle 18 under the constraint of the movable sleeve 17, thereby rotating the movable pin 20 into the fixed pin bracket 21, closing and fixing the front cover 12, and improving stability.
[0028] The supporting structure includes a sliding sleeve 22, a connecting frame 23, a support block 24, a tightening screw sleeve 25, a tightening screw 26, and a tightening handle 27. The outer side of the vertical frame 2 is vertically slidably connected to the inner side of the sliding sleeve 22. The front and rear sides of the sliding sleeve 22 are respectively connected to the bottom middle of a set of support blocks 24 via a set of connecting frames 23. The right middle of the sliding sleeve 22 is connected to the inner side of the tightening screw sleeve 25. The inner wall of the tightening screw sleeve 25 is screwed to the outer wall of the tightening screw 26. The outer side of the tightening screw 26 is connected to the inner middle of the tightening handle 27. When the sliding sleeve 22 is slid upward on the outer side of the vertical frame 2, it can be connected to the support block 24 via the connecting frame 23 to move upward simultaneously. Tightening the tightening handle 27 causes the tightening screw 26 to rotate. The tightening screw 26, after being screwed into the tightening screw sleeve 25, acts inward to tighten at that position on the outer side of the vertical frame 2, thereby acting on the bottom side of the drying cylinder 6 for horizontal support via the support block 24.
[0029] It also includes a drying box 28, an external threaded port 29, and an internal threaded cover 30. The drying box 28 is provided on the inner side of the upper part of the drying cylinder 6. The top of the drying box 28 is connected to the bottom of the external threaded port 29. The outer side of the external threaded port 29 is detachably screwed to the inner side of the internal threaded cover 30. A drying pack can be placed in the drying box 28, and the internal threaded cover 30 can be closed by rotating the screw on the outer side of the external threaded port 29, so that the internal moisture can be absorbed by the external threaded port 29, and the drying pack is easy to replace.
[0030] It also includes a handle 31, with the upper rear part of the drying cylinder 6 connected to the inner side of the handle 31; by holding the handle 31, the drying cylinder 6 can be moved on that side, making it easy to tilt and improving convenience.
[0031] In summary, when using a tobacco processing and drying device, tobacco to be dried can be placed in the inner mesh cylinder 9, with the front cover 12 closed in front of the drying cylinder 6. A drying pack can be placed in the drying box 28, and the inner threaded cover 30 is screwed onto the outside of the external threaded opening 29 to close it, allowing moisture absorption through the external threaded opening 29. When the front cover 12 is closed, the handle 19 can be held, causing the handle shaft 18 to rotate under the constraint of the shaft movable sleeve 17, thereby rotating the moving pin 20 into the fixed pin frame 21, fixing the front cover 12 closed. The closing head 13 blocks the front opening of the inner mesh cylinder 9. During drying, the sliding sleeve 22 slides upwards on the outside of the vertical frame 2, and can be connected to the support block 24 via the connecting frame 23 to move upwards simultaneously. The tightening handle 27 is then turned, causing the tightening screw 26 to rotate. The tightening screw 26 is then screwed onto the tightening sleeve 25. The inner mesh cylinder 9 is rotated by the rotation drive motor 7, which in turn drives the inner mesh cylinder 9 to rotate via the synchronous shaft 8. When the inner mesh cylinder 9 rotates, it can be contacted by the constraint roller 16 and constrained by the inner roller shaft 15 of the shaft frame 14, thus providing movable support to the front outer wall of the inner mesh cylinder 9 to prevent displacement. This allows the tobacco inside to continuously tumble and be heated evenly and quickly dried by the electric heating tube 10 inside the drying cylinder 6. After completion, the locking mechanism is unlocked, and the front cover 12 is opened under the constraint of the hinge 11, which opens the front opening of the inner mesh cylinder 9. After the support is released, the handle 31 can be held and the drying cylinder 6 is connected by the hinge frame 5 and constrained by the hinge shaft 4 to flip over outside the hinge block 3, so that the front side of the drying cylinder 6 and the inner mesh cylinder 9 both face downwards, thus emptying the tobacco.
[0032] The rotary drive motor 7 and the heating element 10 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
