Description

Technical Field

[0001] This utility model relates to the field of cigarette drying, and more specifically, to a device for drying aromatic tobacco. Background Technology

[0002] The most common intensive curing method for aromatic tobacco is the non-woven curing method. This method generally includes steps such as building a shed, harvesting and placing the tobacco leaves in the shed, withering and yellowing, color fixing and sun-drying, drying, and storage. A flat, well-ventilated, and sunny location is selected to build the curing shed. The harvested aromatic tobacco leaves are sorted according to the part of the leaf picked and placed on drying trays in the curing shed. The temperature and humidity inside the curing shed are controlled for drying, requiring manual shading and rotation between trays. Especially for tobacco leaves with relatively small leaves, manual tray rotation and leaf turning are more labor-intensive and increase labor costs. Aromatic tobacco cured in a shed often suffers from a decline in smoking quality due to excessively high shed temperatures and insufficient time for turning. Utility Model Content

[0003] The purpose of this utility model is to provide a tobacco drying device that achieves cyclic drying of tobacco leaves through a drying conveyor belt, a collection basket, and a tobacco leaf collection basket. Subsequent drying only requires manual spreading with wooden sticks, which improves efficiency compared to traditional methods, can be completed quickly by a single person, and greatly reduces costs.

[0004] This utility model is achieved through the following technical solution: A tobacco drying device includes a mounting frame with a drying conveyor belt inclinedly mounted on it. A collection basket is inclinedly mounted on the mounting frame below the drying conveyor belt. The upward-inclined end of the collection basket is longer than the drying conveyor belt. A mounting seat is provided on the downward-inclined side of the drying conveyor belt and the collection basket. A tobacco leaf collection basket is mounted on the mounting seat via a lifting mechanism. The tobacco leaf collection basket is rotated via a rotating mechanism and is initially located below the collection basket.

[0005] Furthermore, the lifting mechanism includes hollow cylindrical columns symmetrically arranged at both ends of the mounting base. Each hollow cylindrical column has a lead screw mounted inside via a lead screw bearing seat. A mounting slider is slidably mounted inside the hollow cylindrical column. The lead screw and the mounting slider are threaded together. A worm gear is provided at the bottom of each lead screw. A transmission worm is mounted on one side of the worm gear via a bearing seat. The transmission worm is driven by a reduction motor. The transmission worm has helical teeth that mate with the worm gears at the two worm gear locations. A long opening is opened inside the hollow cylindrical column. Connecting shafts are installed on both sides of the tobacco leaf collection basket. The connecting shafts pass through the long opening and are mounted inside the mounting slider via bearings. The tobacco leaf collection basket rotates via a rotating mechanism located between the tobacco leaf collection basket and the hollow cylindrical column.

[0006] Furthermore, the mounting slider is provided with grooves on both sides, and the hollow cylindrical column is provided with guide rails on both sides, with the grooves slidingly mounted on the guide rails.

[0007] Furthermore, the rotating mechanism includes a toothed disc and a rack. The toothed disc is fixedly installed on one side of the tobacco leaf collection basket, and a connecting shaft passes through the toothed disc. A rack is installed on the hollow cylindrical column on the side where the toothed disc is installed via a fixing plate. The fixing plate is welded to the hollow cylindrical column, and the toothed disc and the rack mesh.

[0008] Furthermore, photoelectric switches are installed at the top and bottom of both sides of the hollow cylindrical column, and the photoelectric switches are used in conjunction with the tobacco leaf collection basket.

[0009] Furthermore, the tobacco leaf collection basket is a V-shaped collection basket, and the V-shaped structure facilitates the collection and dumping of tobacco leaves.

[0010] Furthermore, the upper opening of the tobacco leaf collection basket is equipped with several baffles, which to a certain extent prevent the tobacco leaves from being scattered onto the drying conveyor belt in a concentrated manner when the tobacco leaf collection basket is rotated and tilted.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The tobacco leaves are dried in a cyclical manner by using a drying conveyor belt, collection trays, and tobacco leaf collection baskets. Subsequent drying only requires manual spreading with wooden sticks, which improves efficiency compared to the traditional method. It can be completed quickly by a single person, greatly reducing costs.

[0012] 2. The tobacco leaf collection basket can be raised and lowered by a single geared motor, and at the same time, the tobacco leaf collection basket can be rotated by the meshing of a gear plate and a rack. The structure is simple, and it can be easily installed in existing greenhouses, making it highly versatile.

[0013] 3. In conjunction with a photoelectric switch, the tobacco collection basket rotates slowly to tilt the tobacco leaves, and the baffle prevents the tobacco leaves from scattering onto the drying conveyor belt in a concentrated manner when the tobacco collection basket rotates and tilts.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 – Figure 3 As shown in the embodiment, a tobacco drying device includes a mounting frame 3. A drying conveyor belt 1 (existing technology) is inclinedly mounted on the mounting frame 3. A collection basket 2 is inclinedly mounted on the mounting frame 3 below the drying conveyor belt 1. The upward inclined end of the collection basket 2 is longer than the drying conveyor belt 1. A mounting seat 10 is provided on the downward inclined side of the drying conveyor belt 1 and the collection basket 2. A tobacco leaf collection basket 8 is mounted on the mounting seat 10 through a lifting mechanism. The tobacco leaf collection basket 8 is rotated through a rotating mechanism. The tobacco leaf collection basket 8 is initially located below the collection basket 2.

[0018] The first drying process requires manually spreading the smaller tobacco leaves evenly on the drying conveyor belt 1 for initial drying. After the first drying, the drying conveyor belt 1 moves the initially dried tobacco leaves to the collection basket 2.

[0019] Specifically, baffles are provided on both sides and the back of the collecting basket 2. When smaller tobacco leaves fall from the drying conveyor belt 1 onto the collecting basket 2, the smaller tobacco leaves slide from the collecting basket 2 into the tobacco leaf collection basket 8 until all the tobacco leaves on the drying conveyor belt 1 are collected in the tobacco leaf collection basket 8.

[0020] In this embodiment, the lifting mechanism includes hollow cylindrical columns 4 symmetrically arranged at both ends of the mounting base 10. A lead screw 6 is installed inside each of the two hollow cylindrical columns 4 via a lead screw bearing seat. A mounting slider 18 is slidably arranged inside the hollow cylindrical column 4. The lead screw 6 and the mounting slider 18 are threaded together. A worm gear 12 is provided at the bottom of each of the two lead screws 6. A transmission worm 11 is installed on one side of the worm gear 12 via a bearing seat 13. The transmission worm 11 is driven by a reduction motor 14. The transmission worm 11 has helical teeth at the worm gears 12 on both sides. A long opening is opened inside the hollow cylindrical column 4. Connecting shafts 19 are installed on both sides of the tobacco leaf collection basket 8. The connecting shafts 19 pass through the long opening and are installed inside the mounting slider 18 via bearings. The tobacco leaf collection basket 8 rotates via a rotating mechanism located between the tobacco leaf collection basket 8 and the hollow cylindrical column 4.

[0021] Specifically, the rotation of the geared motor 14 drives the lead screws 6 on both sides to rotate through the transmission worm gear 11, thereby raising the tobacco leaf collection basket 8. This structure can complete the lifting action with just one motor, making it simple in structure.

[0022] In this embodiment, the mounting slider 18 is provided with grooves on both sides, and the hollow cylindrical column 4 is provided with guide rails 7 on both sides inside, with the grooves sliding on the guide rails 7.

[0023] Specifically, this structure ensures greater stability of the tobacco leaf collection basket 8 during lifting and lowering.

[0024] In this embodiment, the rotating mechanism includes a toothed disc 15 and a rack 17. The toothed disc 15 is fixedly installed on one side of the tobacco leaf collection basket 8, and the connecting shaft 19 passes through the toothed disc 15 (with a gap between them). The rack 17 is installed on the hollow cylindrical column 4 on the mounting side of the toothed disc 15 through a fixing plate 16. The fixing plate 16 is welded to the hollow cylindrical column 4, and the toothed disc 15 and the rack 17 mesh.

[0025] Specifically, the meshing of the toothed disc 15 and the toothed rack 17 allows the tobacco leaf collection basket 8 to rotate during the lifting and lowering process. After rotating, the tobacco leaf collection basket 8 can pour the tobacco leaves inside the tobacco leaf collection basket 8 back onto the drying conveyor belt 1.

[0026] In this embodiment, photoelectric switches 5 are installed at the top and bottom ends of both sides of the hollow cylindrical column 4, and the photoelectric switches 5 cooperate with the tobacco leaf collection basket 8.

[0027] Figure 1 The diagram also shows the partial rotation position of the tobacco leaf collection basket. Specifically, the tobacco leaf collection basket 8 will initially rotate at a relatively high speed during its upward rotation. During this upward rotation, one corner of the tobacco leaf collection basket 8 will be detected by the photoelectric switch 5. When the photoelectric switch 5 at the lower outer side detects the tobacco leaf collection basket 8, the reduction motor 14 will reduce its speed, causing the tobacco leaf collection basket 8 to rotate and tilt slowly during its upward movement, making it easier for the tobacco leaves to fall more evenly onto the drying conveyor belt 1. When the tobacco leaves are tilted, the drying conveyor belt 1 will move slowly to ensure that the smaller tobacco leaves are evenly scattered on the drying conveyor belt 1. When the photoelectric switch 5 at the higher inner side detects the tobacco leaf collection basket 8, the reduction motor 14 will stop rotating. After all the tobacco leaves have fallen from the tobacco leaf collection basket 8 onto the drying conveyor belt 1, the reduction motor 14 will reverse, and the toothed disc 15 and the rack 17 will disengage, causing the tobacco leaf collection basket 8 to return to its starting position.

[0028] In this embodiment, the tobacco leaf collection basket 8 is a V-shaped collection basket.

[0029] Specifically, the V-shaped structure facilitates the collection and dumping of tobacco leaves.

[0030] In this embodiment, the upper opening of the tobacco leaf collection basket 8 is provided with several baffles 9.

[0031] Specifically, the baffle 9, to a certain extent, prevents the tobacco leaves from being scattered onto the drying conveyor belt 1 in a concentrated manner when the tobacco leaf collection basket 8 is rotating and tilting.

[0032] In this embodiment, the surface of the drying conveyor belt 1 is polished to increase the friction of the belt surface and prevent the tobacco leaves from accumulating or sliding down due to the smoothness of the belt.

[0033] Several of these utility models are installed inside a tobacco drying shed, which is 300cm high and has a main gate on the south side. The device is placed oriented north-south, with the north end higher and the south end 50-100cm off the ground. The drying conveyor belt 1 forms a 20°-50° angle with the ground. A 60cm passage is left between each group of devices to facilitate manual spreading of the tobacco leaves with wooden sticks during subsequent drying (since the tobacco leaves are small and have already undergone initial drying, it is acceptable for them to overlap when the tobacco leaves are poured onto the drying conveyor belt 1 in the collection basket 8; they can simply be spread manually). This utility model controls the operation of the reduction motor 14 and the drying conveyor belt 1 via a manual switch (existing technology, not described in detail).
