[0002] At present, in the process of making tobacco leaves into silk, the first step is basically to loosen and rehydrate the tobacco leaves to a certain temperature and moisture content. As the tobacco leaves have been aged for several years, they are sticky to each other. After loosening and rehydrating, not only can the leaves be fully loosened, but also the rehydration of the raw materials with steam will help improve the sensory quality of the tobacco leaves and the absorption of the subsequent liquid. At the same time, after the tobacco leaves are rehydrated to a certain moisture content, the raw materials can be prevented from breaking in the subsequent silk making.

[0003] In the existing tobacco production process, it usually involves complicated process flows such as adding flavoring, adding materials, adding water, adding steam, etc., and the tobacco leaf loosening and rehumidification system usually includes a mixing cylinder, whose function is to add steam again to the tobacco leaves that have been stored for a certain period of time to make them softer, so as to prepare for the subsequent shredding process. In the mixing cylinder, an electronic scale is often set to judge the state of the material in the mixing cylinder, so as to control the mixing cylinder to start the steam switch to steam rehumidify the tobacco leaves in the mixing cylinder. However, compared with the flavoring and adding process, using an electronic scale alone to judge the material state in the mixing cylinder of the loosening and rehumidification process will result in excessively high costs for the tobacco machine equipment, which is not conducive to the development of the enterprise.

[0039] Reference Figure 1 to Figure 2In one embodiment, baffles 130 are extended on both sides of the conveyor belt 120 along the transmission direction, and the baffles 130 on both sides and the conveyor belt 120 enclose a groove-shaped conveying channel 140. The mounting bracket 151 is connected between the baffles 130 on both sides and is located above the conveying channel 140. The material detection sensor 152 is arranged in the middle of the mounting bracket 151, and part of the material detection sensor 152 is located in the conveying channel 140. It can be understood that in order to prevent tobacco leaves from falling from the conveyor belt 120 and to achieve directional flow of tobacco leaves on the conveyor belt 120, this embodiment sets baffles 130 on both sides of the transmission belt to directionally flow the tobacco leaves. The mounting bracket 151 can be erected between the two baffles 130 and located above the transmission channel 140, so that the support setting of the mounting bracket 151 can be reduced. The material detection sensor 152 is set above the transmission channel 140 through the mounting bracket 151. In this way, the material detection sensor 152 can detect the material situation in the transmission channel 140, that is, on the conveyor belt 120, so as to control the opening of the steam mechanism according to the detection result, or at a preset threshold value set in advance by the material detection sensor 152. When the detection result is consistent with the preset threshold value, the opening time of the steam mechanism is determined according to the delay time before, during and after the material detection sensor 152 to the mixing drum 110.

[0040] Reference Figure 2 and Figure 3 In one embodiment, the material detection sensor 152 is vertically arranged above the conveyor belt 120, and the material detection sensor 152 has a detection reference surface 152a, and the detection reference surface 152a is arranged opposite to the conveyor belt 120.

[0041] Reference Figure 3 Furthermore, the material detection sensor 152 includes a signal transmitting port 152b and a signal receiving port 152c, and the signal transmitting port 152b and the signal receiving port 152c are coplanarly arranged on the detection reference surface 152a. In this way, the signal transmitting port 152b and the signal receiving port 152c are arranged closer to the detection target, thereby improving the detection accuracy and reducing external interference.

[0042] Reference Figure 4 In one embodiment, the material detection sensor 152 further includes a display panel 152d, and the display panel 152d and the detection reference surface 152a are arranged opposite to each other on both sides of the material detection sensor 152. In this way, by arranging the display panel 152d and the detection reference surface 152a opposite to each other, it is convenient for the operator to determine the material state in the current mixing drum 110 according to the detection data fed back by the display panel 152d, so as to accurately control the state of the mixing drum 110.

[0044] In one embodiment, the tobacco leaf loosening and rehumidification system 100 further includes a rotary stirring mechanism, which is disposed in the mixing chamber 111 and is used to stir the tobacco leaves in the mixing chamber 111. It is understandable that the rotary stirring mechanism is used to break up the tobacco leaves in the mixing chamber 111 and facilitate the contact between steam and steam, thereby improving the uniformity of tobacco leaf rehumidification and improving the reliability of the tobacco leaf loosening and rehumidification system 100.

[0045] In one embodiment, the tobacco loosening and moisture reconditioning system 100 further includes a controller, which is in communication connection with the material detection sensor 152 and the steam mechanism, and is used to control the switch of the steam mechanism according to the detection data of the material detection sensor 152.
