Description

[0002] In the process of making tobacco, the collected tobacco raw materials need to be naturally fermented, which usually takes about three years. This step is called aging in the tobacco making process. During the aging process, the temperature and humidity need to be strictly controlled within the required range. Therefore, the aging room is generally equipped with relevant dehumidification equipment to adjust the humidity inside the room. The dehumidification equipment will have relevant cold air door control devices inside to control the dehumidification speed.

[0003] Most of the existing cold air door control devices are a plate-shaped air door, which is rotatably installed in the middle of the air duct. By controlling the rotation angle of the air door, the opening amount in the middle of the air duct is controlled, thereby adjusting the air volume and further adjusting the dehumidification speed.

[0004] However, the above-mentioned cold air door control device, when controlling the rotation of the air door, has only one air door. Therefore, when the air door rotates at a small angle, the air flow in the air duct will be very small, resulting in insufficient dehumidification. When it is opened and closed to a certain angle, the air flow will suddenly increase, resulting in excessive dehumidification. It is not convenient to finely control the air flow to adjust the dehumidification. Overall, it has certain defects in use. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0023] Figure 1-5 It is the best embodiment of the utility model, and the following Figure 1-5 The utility model is further described.

[0024] A cold air door control device capable of adjusting the dehumidification amount in stages comprises a mounting tube 1 and a control air door 2 which can be mounted in the middle of an exhaust duct. The control air door 2 is rotatably mounted in the mounting tube 1. The control air doors 2 cooperate with each other to close the mounting tube 1. The control air doors 2 are arranged linearly with their edges close to each other. A driving assembly is mounted on the surface of the mounting tube 1. The control air doors 2 are driven to rotate by the driving assembly. A clutch assembly is arranged between each control air door 2 and the driving assembly. The clutch assembly is used to adjust the rotation amount of the control air door 2 driven by the driving assembly.

[0025] When in use, just install the installation tube 1 in the middle of the exhaust duct, and then drive the control damper 2 to open through the driving component. If the exhaust volume needs to be finely controlled, the number of control dampers 2 opened by the driving component can be adjusted through the clutch component.

[0026] The driving assembly includes a gear 3, a rack 4, a protection box 5 and a first power assembly. The protection box 5 is fixedly mounted on the surface of the mounting tube 1. The gear 3 is rotatably mounted in the protection box 5. The rotating shafts of each control damper 2 can be rotatably extended into the protection box 5. The rotating shafts of each control damper 2 are fixed with a gear 3 through a clutch assembly. The rack 4 is slidably mounted in the protection box 5, and the rack 4 is meshed with the gear 3. The first power assembly is connected to the rack 4, and the rack 4 is driven to slide by the first power assembly. The rack 4 only needs to be driven to slide by the first power assembly, and the rack 4 will drive the gear 3 to rotate. The gear 3 will drive the rotating shaft of the control damper 2 to rotate through the clutch assembly, so that the control damper 2 is opened. In this way, rapid exhaust inside the mounting tube 1 can be achieved.

[0027] The first power assembly includes a driving screw 6, a threaded seat 7 and a handwheel 8. The driving screw 6 is rotatably installed in the protective box 5. The threaded seat 7 is fixedly installed on the surface of the rack 4, and the threaded seat 7 is threadedly connected to the driving screw 6. The handwheel 8 is arranged on the outside of the protective box 5, and the handwheel 8 is fixedly installed on the end of the driving screw 6. In this way, the driving screw 6 can be driven to rotate by simply turning the handwheel 8. The rotation of the driving screw 6 will drive the threaded seat 7 to move, and then drive the rack 4 to slide.

[0028] The clutch assembly includes a first transmission sleeve 9, a second transmission sleeve 10, a first friction disc 11, a second friction disc 12 and a second power assembly. The first transmission sleeve 9 is arranged on the rotating shaft of the control damper 2, and the first transmission sleeve 9 and the rotating shaft of the control damper 2 can rotate relative to each other. The gear 3 is sleeved outside the first transmission sleeve 9 and rotates synchronously with the first transmission sleeve 9. The second transmission sleeve 10 is slidably sleeved outside the first transmission sleeve 9, and the second transmission sleeve 10 can keep synchronous rotation with the first transmission sleeve 9. The first friction disc 11 is fixedly mounted on the rotating shaft of the control damper 2 The second friction disc 12 is fixedly mounted on the end of the second transmission sleeve 10, and the second friction disc 12 is arranged opposite to the first friction disc 11. The second power assembly is connected to the second transmission sleeve 10, and drives the second transmission sleeve 10 to move, so that the second friction disc 12 presses the first friction disc 11 or separates from the first friction disc 11. When the second friction disc 12 presses the first friction disc 11, the gear 3 drives the control damper 2 to rotate. When the second friction disc 12 is separated from the first friction disc 11, the rotation of the gear 3 will not drive the control damper 2 to rotate.

[0029] The second power assembly includes an adjusting screw 13, a first connecting piece 14 and a knob 15. The adjusting screw 13 is arranged in the protection box 5, and the upper end of the adjusting screw 13 passes through the protection box 5 and is fixedly connected with the knob 15. The adjusting screw 13 and the protection box 5 are threadedly connected. The first connecting piece 14 is rotatably mounted on the bottom of the adjusting screw 13, and one end of the first connecting piece 14 away from the adjusting screw 13 is rotatably sleeved outside the second transmission sleeve 10. The first connecting piece 14 can drive the second transmission sleeve 10 to rise and fall. The knob 15 is turned to drive the adjusting screw 13 to rotate, and then the second friction disc 12 is driven to move through the first connecting piece 14, and the second friction disc 12 is closely attached to or separated from the first friction disc 11.

[0030] The clutch assembly also includes a third friction disk 16, a fourth friction disk 17 and a second connecting plate 18. The upper part of the adjusting screw 13 is an optical axis. The second connecting plate 18 is rotatably sleeved on the outer side of the upper part of the adjusting screw 13 and rises and falls synchronously with the adjusting screw 13. The third friction disk 16 is fixedly mounted on the rotating shaft of the control damper 2. The fourth friction disk 17 is slidably sleeved on the rotating shaft of the control damper 2. The fourth friction disk 17 is fixedly connected to the end of the second connecting plate 18 away from the adjusting screw 13. The fourth friction disk 17 is located on the lower side of the third friction disk 16. When the adjusting screw 13 moves upward, the second friction disc 12 is separated from the friction disc 11, and the fourth friction disc 17 is pressed against the third friction disc 16. At this time, the third friction disc 16 is tightly attached to the fourth friction disc 17 to prevent the control damper 2 from rotating freely and opening. When the adjusting screw 13 moves downward, the third friction disc 16 is separated from the fourth friction disc 17, and the first friction disc 11 is pressed against the second friction disc 12, so that the gear 3 drives the control damper 2 to rotate, and the third friction disc 16 and the fourth friction disc 17 are prevented from hindering the rotation of the control damper 2.

[0031] When the first friction disc 11 is in close contact with the second friction disc 12, the third friction disc 16 is not in contact with the fourth friction disc 17. Meanwhile, when the third friction disc 16 is in close contact with the fourth friction disc 17, the first friction disc 11 is separated from the second friction disc 12 to avoid transmission interference.

[0032] The clutch assembly also includes a pointer 19, which is fixedly mounted on the rotating shaft of the control damper 2, and the length direction of the pointer 19 is consistent with the arrangement direction of the control damper 2. A window is provided on the surface of the protection box 5, and the window is facing the pointer 19. The pointer 19 can indicate the status of the control damper 2 in real time, thereby facilitating identification.

[0033] Therefore, the complete usage process is to first install the mounting tube 1 in the middle of the exhaust duct. Then, if the exhaust volume needs to be increased quickly, the knobs 15 can be turned to drive the adjusting screw 13 to rotate, and then the second friction disk 12 is driven to move through the first connecting piece 14, and the second friction disk 12 is made to be close to or separated from the first friction disk 11, and then the hand wheel 8 is turned to drive the driving screw 6 to rotate. The rotation of the driving screw 6 will drive the threaded seat 7 to move, and then drive the rack 4 to slide. The rack 4 will drive the gear 3 to rotate, and the gear 3 will drive the rotating shaft of the control damper 2 to rotate through the first transmission sleeve 9 and the second transmission sleeve 10, so that the control damper 2 is opened. In this way, rapid exhaust inside the mounting tube 1 can be achieved. In the above process, if it is necessary to fine-tune the exhaust volume, one or more knobs 15 can be selectively turned. In this way, only a small amount of ventilation aisle in the middle of the installation tube 1 will be opened, thereby meeting the need for fine exhaust volume adjustment. In addition, it should be noted that when other control dampers 2 that do not need to be opened are in a stationary state, the adjusting screw 13 drives the fourth friction disk 17 to rise and is pressed against the third friction disk 16, thereby fixing the control damper 2 to prevent it from being blown open by the wind.

[0034] In summary, during the entire use process, the exhaust volume is controlled by setting multiple groups of control dampers 2. In this way, according to the demand for exhaust volume, one or more control dampers 2 can be selectively opened to achieve fine control of the exhaust volume, thereby accurately controlling the dehumidification volume.

[0035] At the same time, during use, since multiple groups of control dampers 2 are set up, compared with a single control damper 2, the size of each control damper 2 is smaller, so that the distance between the edge of the control damper 2 and its rotating shaft can be shortened, which will reduce the torque borne by each control damper 2 and play a role in reducing the load, thereby reducing the material performance requirements of the control damper 2, facilitating manufacturing and saving costs.

[0036] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
