[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or in the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, a tobacco hot air moistening ring air inlet and rehumidification device of the utility model comprises a rehumidification cylinder 1 and a processor. The feed end of the rehumidification cylinder 1 is fixedly connected with a feed box 2. The feed box 2 is provided with a hot air duct at one end of the rehumidification cylinder 1. The air outlet of the hot air duct faces the rehumidification cylinder 1. A thermal imaging component for photographing the temperature rise of tobacco in the rehumidification cylinder 1 is installed at one end of the rehumidification cylinder 1. The thermal imaging component photographs the inner wall of the rehumidification cylinder 1. The processor is respectively connected with the thermal imaging component and the hot air duct signal.

[0029] In this embodiment, the processor can be controlled by a single chip microcomputer or a PLC system, and the thermal imaging component uses a thermal imager 4. After obtaining the temperature image of the tobacco, the color and distribution of the pixel points are analyzed by a computer to determine the heating conditions of the tobacco in different areas, thereby adjusting the air output.

[0030] The hot air duct includes a heat supply main pipe and four L-shaped pipes 3. The heat supply main pipe is arranged on the outside of the rehumidification cylinder 1. Through grooves are provided around the feed box 2. The four L-shaped pipes 3 are installed in the corresponding through grooves and are connected to the heat supply main pipe. The air outlet of each L-shaped pipe 3 is installed with an adjusting air valve 31. When the rehumidification cylinder 1 is feeding, the tobacco in the upper part falls back to the lower part, and the tobacco in the rehumidification cylinder 1 is uneven. By arranging the L-shaped pipes 3 circumferentially around the rehumidification cylinder 1, the rehumidification cylinder 1 is divided into four areas for parallel air supply. The air supply volume of each area is adjusted according to the distribution of tobacco in the rehumidification cylinder 1 to ensure that the tobacco in the rehumidification cylinder 1 is evenly heated.

[0031] In this embodiment, when the rehumidification drum 1 is spirally fed, the tobacco in the lower part is first transmitted to the left side, then to the upper part, and finally returns to the lower part through the right side. When the tobacco is in an oblique upward position, some of the looser tobacco breaks away and falls to the lower part. It can be seen that there is more tobacco accumulated in the lower part and the left side. According to the distribution of the tobacco, the air outlet of each L-shaped tube 3 is adjusted to make the tobacco heated more evenly.

[0032] There are three thermal imagers 4, one of which is obliquely installed at the upper end of the feed box 2, and the other two thermal imagers 4 are respectively installed on the L-shaped tubes 3 on both sides. In fact, two, four, or other numbers of thermal imagers 4 can also be selected according to actual conditions. In this embodiment, the actual temperature of the tobacco at the lower part of the tempering cylinder 1 is obtained by the thermal imager 4 at the upper end, and the thermal imagers 4 at the left and right ends obtain the tobacco temperature at the upper part and both sides of the tempering cylinder 1. According to the actual temperature of the tobacco in multiple areas, the air outlet of the corresponding L-shaped tube 3 is adjusted to ensure that the tobacco is heated evenly.

[0033] The regulating air valve 31 includes a fixed plate 32 and a movable plate 33. The fixed plate 32 is fixedly installed at the air outlet of the L-shaped tube 3. A slide groove is provided on one side of the fixed plate 32 of the L-shaped tube 3. The movable plate 33 is vertically slidably installed in the slide groove and rests on the fixed plate 32. A plurality of air holes 34 are provided on the fixed plate 32 and the movable plate 33. A servo motor 35 is installed on the L-shaped tube 3. The output end of the servo motor 35 is connected to a gear 36. One end of the movable plate 33 is fixedly connected to a rack 37. The rack 37 is meshed with the gear 36. The servo motor 35 is connected to the processor signal. In fact, according to actual conditions, the air intake can also be adjusted by using a motor to adjust the flap. In this embodiment, the servo motor 35 drives the gear 36 to rotate, so that the rack 37 drives the movable plate 33 to move up and down, so that the air holes 34 are aligned or offset, thereby controlling the air outlet of the L-shaped tube 3.

[0034] The outside of the servo motor 35 is wrapped with a heat insulation cover 38. The heat insulation cover 38 reduces the temperature of the servo motor 35 and increases the service life.

[0035] The usage and principle of this embodiment are as follows:

[0036] The hot air duct is started, and the tobacco continuously enters the rehumidification cylinder 1 through the feed box 2. The rehumidification cylinder 1 spirally transports the tobacco and humidifies it. After the hot air heats the tobacco, the water absorption of the tobacco is improved;

[0037] The temperature rise of tobacco in the rehumidification cylinder 1 is photographed by a thermal imager 4, and the regulating air valve 31 corresponding to each L-shaped tube 3 is adjusted according to the actual temperature of tobacco in each area;

[0038] The processor transmits the adjustment signal to the corresponding servo motor 35, the servo motor 35 drives the gear 36 to rotate, the gear 36 drives the rack 37 to move, and then the movable plate 33 moves linearly, and the air volume of the L-shaped tube 3 is controlled by the overlap between the movable plate 33 and the air hole 34 on the fixed plate 32;

[0039] The thermal imager 4 and the regulating air valve 31 cooperate with each other to adjust the air supply volume in the rehumidification cylinder 1 in real time, so that the tobacco is evenly heated and the temperature reaches the rehumidification requirement, thereby improving the quality of the tobacco.

[0040] The above is a detailed introduction to a tobacco hot air moistening leaf ring air inlet and rehumidification device provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
