Description

Technical Field

[0001] The present invention relates to a device for a centralized control intelligent manufacturing tower-type cut tobacco expansion process, belonging to the technical field of tobacco equipment. Background Art

[0002] Cut tobacco drying is one of the very important links in the entire tobacco production. The quality of cut tobacco drying is directly related to the quality of the final product. The tower-type pneumatic cut tobacco dryer is a commonly used cut tobacco drying device in cigarette making. It is a device that uses high-temperature process gas generated by a combustion furnace to dry the expanded cut tobacco in a drying tower, and has the advantages of short drying time, high thermal efficiency, good drying effect, etc. It has great advantages especially in processing a large quantity of cut tobacco.

[0003] Currently, the Chinese invention patent with the publication number CN113349402A discloses a loosening device for a pneumatic cut tobacco dryer, including a housing, a loosening roller, and a driving mechanism. A first end cover is provided at the left end of the housing, a second end cover is provided at the right end, a feed inlet is provided at the upper end, and a discharge outlet is provided at the lower end; the second end of the loosening roller is rotatably connected to the second end cover, the first end of the loosening roller passes through the first end cover and is connected to the driving mechanism, and the loosening roller is rotatably connected to the first end cover; the driving mechanism is used to drive the loosening roller to rotate. Four rake nail groups are evenly distributed in the circumferential direction of the loosening section of the loosening roller. Each rake nail in the rake nail group is evenly distributed in the axial direction of the loosening section, and the rake nail is vertically connected to the loosening section. In the direction from the first end to the second end, the lengths of the rake nails in each rake nail group first gradually become longer and then gradually become shorter, and the length of the rake nail at the middle position of the loosening section is the longest. This invention can better avoid the intermittent falling phenomenon of cut tobacco leaves, ensuring that the discharge at the discharge outlet is relatively uniform and continuous. However, during the long-term use of this device, its turning door will wear against the inner side wall of the feed air lock, resulting in an impact on its sealing effect, and further affecting the cut tobacco drying work of the device.

[0004] Therefore, the key to solving the above technical problems is to develop a device for a centralized control intelligent manufacturing tower-type cut tobacco expansion process that is convenient to adjust, practical and reliable. Summary of the Invention

[0046] Preferably, the adjusting assembly (6) includes:

[0047] An adjusting column (61), one end of the adjusting column (61) is sleeved and connected to the outside of a support column (423), and the other end of the adjusting column (61) is threadedly connected to an internal threaded section of a connection block (424);

[0048] Several adjusting sleeves (62), several adjusting sleeves (62) are sleeved and connected to the adjusting column (61).

[0049] Preferably, the adjusting column (61) is integrally in a cylindrical structure. One end of the adjusting column (61) is internally provided with an adjusting groove adapted to the support column (423); the other end of the adjusting column (61) is provided with an external thread section adapted to the internal thread section of the connecting block (424);

[0050] The adjusting sleeve (62) is mainly formed by fixedly connecting a frustum-shaped structure with a hollow interior and a cylindrical structure with a hollow interior;

[0051] Wherein, an adjusting knob (63) is further connected to the end of the external thread section of the adjusting column (61).

[0052] The working principle is as follows: When the present invention is in use, the cut tobacco (8) first passes through an external high-frequency vibrating trough to preliminarily loosen the cut tobacco (8). Then, the preliminarily loosened cut tobacco (8) enters the interior of the fixed box (3) through the feed port and falls between the two mounting brackets (422) of the flipping device (4); the driving motor (41) starts to work, and the output shaft of the driving motor (41) drives the driving pulley (43) to rotate. Further, the driving pulley (43) drives the fixed sleeve (421) to rotate, so that the fixed sleeve (421) drives a plurality of mounting brackets (422) fixedly connected thereto to rotate, and drives the flipping assembly (44) mounted on the mounting brackets (422) and the sealing assembly (45) connected to the flipping assembly (44) to rotate. Finally, the preliminarily loosened cut tobacco (8) is conveyed below the fixed box (3) through the flipping device (4);

[0053] During the rotation of the output shaft of the driving motor (41), it drives the driving pulley (43) to rotate. The driving pulley (43) drives the driven pulley (53) to rotate through the transmission member (7), and further drives the loosening assembly (5) to work. The driven pulley (53) drives the rotating shaft (51) to rotate, and further drives the flipping blades (52) connected to the rotating shaft (51) to rotate. The loosening assembly (5) thus loosens the cut tobacco (8) discharged from the flipping device (4) again. Then, the cut tobacco (8) and the high-temperature steam inside the high-temperature steam expansion unit (2) are simultaneously sprayed and sent into the drying tower (1). The high-temperature gas will fully contact and dry the expanded cut tobacco inside the drying tower (1), and then is transported to an external tangential feeder through an external pipeline to separate the low-temperature gas from the expanded cut tobacco. The separated dried and expanded cut tobacco enters an external downstream device for production and processing. Among them, part of the low-temperature gas is transported to an external combustion furnace after removing moisture by an external moisture exhaust device and is reheated to a set temperature to provide high-temperature gas for the high-temperature steam expansion unit (2) and the drying tower (1) to ensure the overall processing continuity of the equipment;

[0054] During use, when the air pressure monitoring device inside the fixed box (3) detects a large change, manually rotate the adjustment knob (63) to drive the adjustment column (61) to rotate, and then make the adjustment sleeve (62) contact the ball (4421) on the flipping assembly (44). When the ball (4421) contacts the adjustment sleeve (62), the outer diameter of the contact surface between the adjustment sleeve (62) and the ball (4421) gradually increases, thereby squeezing the connecting column (442) to move towards the inner wall of the fixed box (3), so that the flipping plate (441) drives the sealing scraper (454) to move towards the inner wall of the fixed box (3), thereby adjusting the use gap between the inner wall of the fixed box (3) and the sealing scraper (454).

[0055] During use, when the sealing scraper (454) needs to be replaced after long-term use, the operator separates the locking part (455) from the connecting strip (452) with tools. Then, the operator separates the clamping block (453) from the clamping block installation groove (4411). Immediately afterwards, the operator extracts the old sealing scraper (454) from the connecting strip (452), replaces it with a new sealing scraper (454). Finally, the operator clamps the clamping block (453) in the clamping block installation groove (4411), and passes the locking part (455) through the connecting hole of the clamping block (453) to tightly connect the sealing scraper (454) to the upper side of the flipping plate (441), that is, quickly complete the disassembly and replacement work of the sealing scraper (454).

[0056] The beneficial effects of the present invention compared with the prior art are as follows:

[0057] 1. The present invention can assist in reducing the gap between the inner wall of the fixed box and the sealing scraper to prevent leakage at the joint between the sealing scraper and the fixed box due to wear during long-term use of the equipment;

[0058] 2. The reasonable design of the sealing assembly (45) of the present invention can prevent some tobacco shreds from winding around the sealing scraper (454), thereby preventing the tobacco shred drying work of the equipment from being affected, and then improving the reliability and operation efficiency of the equipment;

[0059] 3. The present invention is provided with an adjustment assembly (6), which can assist in adjusting the distance between the sealing scraper (454) and the inner wall of the fixed box (3) through the cooperation of the adjustment assembly (6) and the flipping device (4);

[0060] 4. The present invention is provided with a loosening assembly (5) so that the tobacco shreds conveyed by the flipping device (4) can be fully contacted with the high-temperature steam inside the high-temperature steam expansion unit (2) after entering it, which helps to improve the overall drying efficiency of the equipment for tobacco shreds;

[0061] 5. The design of the present invention is ingenious. The flipping device (4) drives the loosening component (5) to operate through the transmission member (7), simplifying the design of the driving device, avoiding the design and debugging process of complex transmission devices, thereby reducing complexity and improving reliability. At the same time, it improves production efficiency and cost-effectiveness;

[0062] 6. The present invention is provided with a sealing component (45), which can better ensure the tightness and uniformity of the cut tobacco in each flipping bin of the flipping frame (42). At the same time, it reduces the mixed flow of cut tobacco in adjacent flipping bins, improves production efficiency, and ensures the consistency of the cut tobacco in each flipping bin;

[0063] 7. The sealing component (45) of the present invention can quickly replace and install the sealing scraper (454), which helps to reduce the maintenance time and ensure the integrity of the sealing component (45) when replacing or installing the sealing scraper (454), effectively ensuring the portability and applicability of the equipment;

[0064] 8. One end of the connecting column (442) of the present invention is internally rotatably connected with a ball (4421), which can reduce the friction and energy loss between the ball (4421) and the adjusting component (6), making the adjustment process more efficient and convenient, and reducing the power requirement of the operator;

[0065] 9. The present invention can conveniently adjust the distance between the sealing scraper and the inner side surface of the fixed box, preventing the high-temperature gas inside the high-temperature steam expansion unit from entering the external high-frequency vibration tank through the fixed box during the transportation of cut tobacco, resulting in the overflow of high-temperature gas. This not only prevents the impact on the cut tobacco transportation effect of the equipment but also prevents the impact on the drying efficiency of the equipment;

[0066] 10. Since the present invention is provided with an adjusting component (6), it can increase the service time of the sealing scraper (454), reduce the frequency of replacing the sealing scraper (454), and thus improve the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting assembly 6 can assist in adjusting the distance between the sealing scraper 454 and the inner side wall of the fixed box 3 through the cooperation of the adjusting assembly 6 and the flipping device 4; at the same time, due to the provision of the adjusting assembly 6, the service life of the sealing scraper 454 can be increased, the number of times of frequently replacing the sealing scraper 454 is reduced, and thus the work efficiency is improved.

[0136] Further, as Figure 13 shown, the adjusting column 61 is integrally in a cylindrical structure, and one end of the adjusting column 61 is provided with an adjusting groove adapted to the support column 423 inwardly; the other end of the adjusting column 61 is provided with an external thread section adapted to the internal thread section of the connecting block 424;

[0137] The adjusting sleeve 62 is mainly formed by fixedly connecting a frustum-shaped structure with a hollow interior and a cylindrical structure with a hollow interior;

[0138] Wherein, an adjusting knob 63 is further connected to the end of the external thread section of the adjusting column 61.

[0139] Further, as Figure 4 and Figure 5 shown, the fixed box 3 is a communicating box structure with a hollow interior, square ends, and a circular middle;

[0140] The transmission member 7 is a conveyor belt, and the transmission member 7 is surrounded and connected to the driving pulley 43 and the driven pulley 53.

[0141] In summary, a more specific implementation method is as follows:

[0142] Embodiment 1

[0143] During use, the cut tobacco 8 first passes through an external high-frequency vibrating trough to preliminarily loosen the cut tobacco 8. Then, the preliminarily loosened cut tobacco 8 enters the interior of the fixed box 3 through the feed port and falls between the two mounting brackets 422 of the turning device 4. The driving motor 41 starts to work, and the output shaft of the driving motor 41 drives the driving pulley 43 to rotate. Furthermore, the driving pulley 43 drives the fixed sleeve 421 to rotate, so that the fixed sleeve 421 drives a plurality of mounting brackets 422 fixedly connected thereto to rotate, and drives the turning assembly 44 mounted on the mounting brackets 422 and the sealing assembly 45 connected to the turning assembly 44 to rotate. Finally, the preliminarily loosened cut tobacco 8 is conveyed below the fixed box 3 through the turning device 4;

[0144] During the rotation of the output shaft of the driving motor 41, it drives the driving pulley 43 to rotate. The driving pulley 43 drives the driven pulley 53 to rotate through the transmission member 7, and then drives the loosening assembly 5 to work. The driven pulley 53 drives the rotating shaft 51 to rotate, and then drives the turning blades 52 connected to the rotating shaft 51 to rotate. The loosening assembly 5 thus loosens the cut tobacco 8 discharged from the turning device 4 again. Then, the cut tobacco 8 and the high-temperature steam inside the high-temperature steam expansion unit 2 are simultaneously sprayed and sent into the drying tower 1. The high-temperature gas will fully contact and dry the expanded cut tobacco inside the drying tower 1, and then is conveyed to an external tangential feeder through an external pipeline to separate the low-temperature gas from the expanded cut tobacco. The separated dried and expanded cut tobacco enters an external downstream device for production and processing. Among them, part of the low-temperature gas is sent to an external combustion furnace after moisture is removed by an external moisture exhaust device and reheated to a set temperature to provide high-temperature gas for the high-temperature steam expansion unit 2 and the drying tower 1 to ensure the overall processing continuity of the equipment.

[0145] Embodiment 2

[0146] When the air pressure monitoring device inside the fixed box 3 detects a large change, manually rotate the adjustment knob 63, so that the adjustment knob 63 drives the adjustment column 61 to rotate, and then the adjustment sleeve 62 contacts the ball 4421 on the flipping assembly 44. When the ball 4421 contacts the adjustment sleeve 62, the outer diameter of the contact surface between the adjustment sleeve 62 and the ball 4421 gradually increases, and then presses the connecting column 442 to move towards the inner wall of the fixed box 3, so that the flipping plate 441 drives the sealing scraper 454 to move towards the inner wall of the fixed box 3, thereby adjusting the use gap between the inner wall of the fixed box 3 and the sealing scraper 454; during use, under the elastic action of the buffer spring 444, it can better ensure the adjustment work of the connecting column 442 and the adjustment assembly 6.

[0147] Embodiment 3

[0148] When the sealing scraper 454 needs to be replaced after long-term use, the operator separates the locking part 455 from the connecting bar 452 with tools. Then, the operator separates the clamping block 453 from the clamping block installation groove 4411. Immediately afterwards, the operator extracts the old sealing scraper 454 from the connecting bar 452, replaces it with a new sealing scraper 454. Finally, the operator clamps the clamping block 453 in the clamping block installation groove 4411, and passes the locking part 455 through the connecting hole of the clamping block 453 to tightly connect the sealing scraper 454 to the upper side of the flipping plate 441, that is, quickly complete the disassembly and replacement work of the sealing scraper 454.
