[0054] First, a plurality of cigar wrapper tobacco bunches are respectively hung on a plurality of hanging stations on the hanging section of the hanging rod 6. During the hanging process, the movable pressing plate 34 is first pulled forward, the spring 38 is stretched, and a plurality of pins 39 move forward together with the movable pressing plate 34, so that the gap between the plurality of pins 39 and the fixed back plate 35 increases. At this time, the cigar wrapper tobacco bunches can be inserted from bottom to top into the gap between the pins 39 and the fixed back plate 35, and then the movable pressing plate 34 is released. Under the elastic force of the spring 38, the movable pressing plate 34 and the plurality of pins 39 automatically move backward and reset, and the cigar wrapper tobacco bunches can be clamped by the plurality of pins 39 and the fixed back plate 35.

[0055] Then, the two ends of the hanging rod 6 with multiple cigar wrapper tobacco bunches are hung on the corresponding feeding support blocks 8 of the left and right feeding conveyor chains 3. Start the spraying mechanism and the transmission mechanism, and drive the operation of the chains in the feeding conveyor section, the flipping conveyor section, and the discharging conveyor section through the transmission mechanism. As the two feeding conveyor chains 3 operate, the left and right ends of the corresponding hanging rod 6 are pushed by the left and right feeding push plates 7, so that the hanging rod 6 and the feeding conveyor chain 3 are conveyed from front to back together. When the hanging rod 6 runs backward to the first inclined guiding section 9 close to the flipping conveyor chain 4, the flipping push plate 11 on the first inclined guiding section 9 lifts the hanging rod 6 conveyed by the feeding conveyor chain 3 out of the feeding conveyor chain 3 and conveys it obliquely backward and upward into the horizontal flipping section 10 of the flipping conveyor chain 4 for horizontal conveyance. During this process, through the cooperation of several gaps of the flipping bracket 14 and multiple teeth 13 at the end of the hanging rod 6, the hanging rod 6 is driven to rotate while being conveyed, so that multiple cigar wrapper tobacco bunches hung on the hanging rod 6 rotate while being conveyed. Cooperating with the spraying mechanism to atomize and humidify the cigar wrapper tobacco bunches, the atomized water can be sprayed into the interior of the cigar wrapper tobacco bunches, improving the moisture regain effect and efficiency. When the hanging rod 6 moves backward to the rear end of the horizontal flipping section 10 of the flipping conveyor chain 4, under the guiding action of the left and right inclined guide plates 19, the two ends of the hanging rod 6 respectively enter the discharging push plates 18 on the second inclined guiding sections 16 of the two groups of discharging conveyor chains 5, and the hanging rod 6 is conveyed backward by the discharging conveyor chain 5, and the worker takes out the hanging rod 6 with the humidification completed, completing the humidification operation.

[0056] During the humidification process, the air circulation mechanism 21 is started simultaneously. Under the power action of the fan 22, the hot and humid air in the moisture regain cavity 2 is sucked from multiple air suction holes through the air suction pipe 23 and blown upward into the moisture regain cavity 2 from multiple air blowing ports 27 at the bottom of the drainage tank body 26 through the air outlet pipe 24. Used in cooperation with the spraying mechanism, the atomized water with a certain temperature sprayed by the spraying mechanism forms a warm and humid air flow from bottom to top inside the moisture regain cavity 2 under the action of the air circulation mechanism 21, and tries to keep the interior of the moisture regain cavity 2 in a constant temperature and humidity state, so as to make the moisture regain of the cigar wrapper tobacco bunches more uniform and stable. The condensed water formed by the hot and humid air in the moisture regain cavity 2 of the moisture regain box 1 is discharged through the main drainage port 29 of the drainage tank body 26. The condensed water formed in the air circulation pipeline is discharged through the air circulation drainage pipe 30 connected to the bottom of the air outlet pipe 24.

[0057] In order to verify the moisture regain effect of the moisture regain device provided in this embodiment, the applicant's test operation of using this moisture regain device to carry out moisture regain on cigar wrapper tobacco bunches is as follows:

[0058] First, set the relevant parameters of the moisture regain device as:

[0059] The rotational speed of the motor 40 is 7.8 revolutions per minute, the running speed of the feeding conveyor chain 3 is 0.3 meters per minute, the running speed of the flipping conveyor chain 4 is 2.1 meters per minute, the running speed of the discharging conveyor chain 5 is 0.3 meters per minute, and the steam ejection pressure of the steam ejection atomizing nozzle 20 in the spraying mechanism is 0.1 Mpa and the water pressure is 0.13 Mpa.

[0060] Before using this conditioning device, first humidify and pre-treat the cigar wrapper tobacco bundles using a vacuum conditioning machine. The cigar wrapper tobacco bundles after the humidifying pre-treatment are used as the conditioning raw materials for this conditioning device. Hang each bundle of conditioning raw materials on the hanging rod 6, and then place each hanging rod 6 in this conditioning device for conditioning operations. After the conditioning operations, place them in a plastic box for 6 hours to balance, and the results of randomly sampling and testing the moisture content of the cigar wrapper tobacco bundles before and after conditioning are shown in Table 1:

[0061] Table 1 Test results of the moisture content of cigar wrapper tobacco bundles before and after conditioning

[0062]

[0063]

[0064] As can be seen from Table 1, after the cigar wrapper tobacco bundles are conditioned by the conditioning device provided in this embodiment, the difference in the moisture content inside and outside the cigar wrapper tobacco bundles is small, the moisture inside and outside the cigar wrapper tobacco bundles is uniform, and the moisture content uniformity and stability are good.

[0065] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
